MHS BOILERS IS TOP OF THE CLASS IN ULTRA-EFFICIENT HEATING

Mon, 09 Jan 2012 10:01:01 GMT

Pupils and staff at Dr Thomlinson’s Church of England Middle School in Rothbury, Northumberland, are benefitting from ultra-efficient, heating and hot water thanks to two 251kW fully condensing, gas-fired Ultramax R603 boilers, supplied by MHS Boilers, part of Elco Heating Solutions. Replacing an ageing gas-fired system, the installation is designed to increase energy efficiency and reduce the carbon footprint for the school.

The M&E Contractors were Cleveland based Geoffrey Robinson Ltd. Commenting on MHS Boilers, Duncan Greenock, Project Engineer, Geoffrey Robinson Ltd, said: “When efficiency is a priority the Ultramax R600 fully-condensing, gas-fired boilers are the ideal choice. Their compact size is also suited to the restricted plant space within this particular school, plus they are conveniently designed to pass through standard doors which made life much easier during installation.” The consultants were Co Durham-based Ian Carswell Associates.

The Ultramax R600 range of boilers has a NOx emission of less than 35mg/kWh (which easily exceeds the requirements for the best BREEAM score) and can return efficiencies of up to 109%. Designed to pass through standard doors, Ultramax R600 boilers have widths from 670mm and floor space is kept to a minimum with a footprint from as small as 0.74m2.

Each model is equipped with two return connections as standard, allowing high efficiency to be achieved when serving a mix of higher and lower system load circuit temperatures. Another standard feature is the option to utilise room sealed or open flue systems.

Ultramax R600 boilers are suitable for use in single boiler or multiple/cascade installations. If used singly MHS Boilers can supply plug and play optional extra low loss headers, and if being used as retrofit appliances onto aged systems, a matched boiler protection plate heat exchanger unit is available for total boiler isolation. The modulating burner system allows turndown ranging from 5:1 to 7:1 to return optimum efficiency at low system loads. And for complete peace of mind, an optional annual service agreement from MHS Boilers extends theirguarantee to 10 years – which means you can rest assured that all parts and labour for breakdown or servicing will be covered.

The school was founded in 1720 with funds left by the Reverend Doctor Thomlinson. His vision was to create a non-fee paying grammar school.

RUCKING WITH THE BEST

Wed, 14 Dec 2011 11:12:01 GMT

MHS Boilers has supplied three 120kW Thision L boilers and 10m² of its Solatron S2.5 flat panel solar collectors to the recently opened Parc Eirias Events Centre in Colwyn Bay, North Wales. The Thision L boilers were installed in a wall-mounted cascade frame with a low loss header.

The Parc Eirias Events Centre is a cornerstone of regeneration plans for Colwyn Bay and provides a venue for community, cultural and sporting events. The Pound6.5m project has taken eight months to complete and now comprises a large multi-purpose indoor centre for recreational use, as well as a conference centre for business and commercial events.

The Thision L boilers were specified by Denbigh-based M&E consultants, Carpenter Davies Partnership Ltd. Commenting on MHS Boilers, Director, Ian Carpenter, said: “We have always had a strong relationship with MHS and have worked with them on a variety projects over the years. With Parc Eirias, we needed to specify boilers that provided excellent efficiencies in a compact design, which made the Thision L a great choice.”

M&E contractors for the project were Wrexham-based JRS Mechanical Services Ltd. Matt Foster of JRS said: “Installation and commissioning of the boiler plant went really well and we were especially pleased with the cascade kit for the Thision L. It really helped to make it a quick and simple process.”

Thision L is a brand new range of light commercial gas fired, high efficiency, wall-hung condensing boilers with outputs from 45kW to 145kW. Featuring a double helix stainless steel heat exchanger, the boilers have a high turndown rate of 6:1, allowing the potential for accurate output-to-load matching.

Up to eight boilers can be installed in a purpose-built cascade rig delivering an industry leading combined output of up to 1,140kW. The on-board controls of the Thision L include the management of two heating zones plus the charging of a domestic hot water cylinder. The system is also easily adapted to provide multi-boiler cascade management.

The double helix stainless steel heat exchanger at the heart of the Thision L combines high quality materials and ingenious engineering to produce a highly efficient appliance. Thanks to its stainless steel construction the heat exchanger will maintain efficiency over its lifetime, and is more resistant to corrosion and material degradation compared to traditional aluminium counterparts.

Solatron S2.5 is an easy to install, low cost and highly efficient flat panel solar collector, which can be mounted in-roof, on-roof or in-frame. The state-of-the-art collector has been designed to be versatile, economic and incredibly easy to fit – needing only a cordless screwdriver, a hammer and a tape measure.

The panels are available in both horizontal and vertical hydraulically-optimised versions with each orientation supplied with matching mounting systems and roof flashings. Collector fields can be created from multiple panels, and the connections are simple requiring the minimum of tools.

MHS Boilers at Historic Norfolk Building

Thu, 08 Dec 2011 12:12:01 GMT

MHS Boilers has supplied two high output Ultramax PB 120 kW condensing boilers to Bishops Lynn House in Kings Lynn, Norfolk. Installed in the vaulted cellar of the Grade II listed building, the boilers have been integrated with the existing heating system using a plate heat exchanger kit – also supplied by MHS Boilers.

Dating from the 17th Century with a major four-storey office extension constructed in the 1970’s, Bishops Lynn House is situated on the corner of the Tuesday Market Place, which is one of the largest medieval town squares in Northern Europe. Such an historic building presented major challenges to the installers, particularly with access to the plant room. Steve Stone of Stone Engineering Consultants commented: “The age and design of the building meant that access to the plant room was restricted, making the compact Ultramax PB boilers the perfect choice. Throughout the project, MHS supplied some excellent advice and were great to work with.”

The Ultramax PB from MHS Boilers solves the problem of fitting a brand new, energy efficient, high performance condensing boiler to an old system, thanks to its use of simple separator technology. A plate type heat exchanger option kit can easily be incorporated into the Ultramax PB boiler case to act as a barrier, protecting the boiler from the effects of dirt accumulation in older systems. In addition the Ultramax PB premix burner is able to overcome difficult flue arrangements. For example at this installation new liners were fed down the existing chimneys to act as flues for the boilers. The space between the liner and the chimney was used to bring fresh air for combustion direct to the boilers. The remaining, redundant third chimney is now used as high level ventilation for the plant room.

Available in four models (65kW, 85kW, 100kW and 120kw) the Ultramax PB has a small footprint, taking up less than 0.51m², making it ideal where boiler room space is at a premium. However, its compact size belies its power and efficiency. Its pre-mix modulating burner gives a return efficiency of up to 109.8% and a modulation range up to 6:8:1. What’s more its NOx emission does not exceed 33 mg/kWh – easily meeting the stringent requirements for the highest BREEAM points score for low NOx pollution. The Ultramax PB is also very quiet with noise levels not exceeding 48 dBA.

A comprehensive programmable boiler/system controller is included as standard, which allows connection to intelligent room controls if required, and the Ultramax PB’s flue connection is suitable for either room sealed or open type systems with the capability for extensive lengths of flue to be accommodated.

The Ultramax PB also has an on-board direct weather compensator which provides both comfort and energy efficiency for the end user. For peace of mind, the primary heat exchanger carries a five-year guarantee.

EFFICIENT AND EFFECTIVE HEATING IS ON THE CURRICULUM AT PENTLAND PRIMARY

Tue, 15 Nov 2011 15:11:01 GMT

MHS Boilers, part of Elco Heating Solutions, has supplied two Ultramax Thision L boilers and a freestanding in-line cascade system, with plate heat exchanger, to Pentland Primary School, Stockton–on–Tees.

Pentland Primary School has more than 330 pupils, aged between four and 11 years old and at least 35 members of staff. This large primary school serves the majority of families in the Billingham area, and so it was essential to find a boiler system fit for purpose as quickly as possible, when the existing aging one needed replacing.

The school has a small plant room with restricted height and floor space, so it was important that any new appliances had a low carbon footprint and were able to fit in the existing plant room space. The installers for Pentland Primary School were Twin Services Ltd, based in Stockton-on-Tees. Peter Kemp, Project Manager, Twin Services Ltd, said: “The compact and energy efficient design of the Thision L in cascade was a key factor for this particular school. Maintaining effective heat outputs, while keeping the carbon footprint to a minimum was the main priority, which we delivered successfully with MHS.” Stockton Borough Council specified the Ultramax Thision L boilers in cascade and recommended that MHS Boilers were chosen to fulfil the requirements of the school heating system.

The ultra-efficient Ultramax Thision L

The UltramaxThision L boilers are a range of light industrial gas fired, high efficiency, wall-hung condensing boilers with outputs from 65kW to 145kW. Featuring a double helix stainless steel heat exchanger, the boilers have a high turndown rate of 6:1 – enabling heating and hot water demand to be matched with incredible accuracy. They are also equipped with a modulating control system which not only adjusts the firing rate of the burner but with the addition of a control module may also drive a variable speed pump if desired. The boiler’s default setting is for a constant flow temperature, but with the addition of an optional outside air temperature sensor, weather variable temperature can also be provided.

The cool flame, low emission premix burner system provides an extremely low NOx, whilst the stainless steel heat exchanger returns a long and reliable service life of non-fading top level efficiency. The heat exchanger’s water ways consist of a pair of stainless steel finned tubes arranged in a vertical double helix with low hydraulic resistance. The 1:6 modulation ratio of the burner control system in the Thision L allows optimum seasonal efficiency through its ability to closely follow changes in load, whilst environmental impact is kept to a minimum through NOx emission of less than 38mg/kWh @ 0% O² (which adequately exceeds the requirements for the highest BREEAM credits). Another standard feature is the option to utilise room-sealed or open flue systems. Thision L is the latest addition to the popular and extremely well regarded Ultramax family of boilers from MHS, setting new benchmarks in reliability, performance and design features.

A focus on the cascade system

Up to eight boilers can be combined in a purpose-built cascade rig system from MHS Boilers comprising two sets of components: a boiler cascade set, which consists of a mounting frame complete with interconnecting gas and water pipes and a flue cascade set which provides an off-the-peg arrangement for connecting all of the individual module’s flues together into a common duct. Both sets of components have been designed and engineered to complement each other.

The cascade frame sets are available with either a standard low loss header or an optional header which incorporates dirt and air separation. Both types of header are available with either DN65 or DN100 system connection sizes. For complete hydraulic separation, cascade sets incorporating a plate heat exchanger (as an alternative to a low loss header) are available for systems with outputs up to 462kW. The inclusion of a communication module into each boiler enables the cascading capability of the controls, and all that is further required to complete the cascade function, is the installation of a temperature sensor onto the low loss header or the main flow pipe of the system.

A WORLD OF ARTS APART

Mon, 26 Sep 2011 13:09:01 BST

Staff and visitors to The Hub, Edinburgh’s Festival Centre on the Royal Mile, are benefitting from efficient heating thanks to three ADI-NOx LT 150kW boilers and a Pisces pressurisation unit – all supplied by MHS Boilers. The installation was part of the complete refurbishment of the heating system in the 19th century Grade A listed building.

The installers were Paisley-based Taylor and Fraser Ltd which has a long established and unrivalled reputation for working in historic buildings. M&E consultant engineers for the project were Arup.

The ADI-NOx ADI range of high efficiency boilers solve the problems caused by replacing old atmospheric boilers in compact plant rooms. With outputs from 68 to 905kW, it is designed to resolve difficulties with limited installation space. The boilers have incredibly compact dimensions that belie their powerful outputs. For example, models of up to 110kW output are only 350mm wide – making access and retrofitting much easier. And space saving is not just confined to the smaller outputs, as the boilers at 905kW only occupy 1.2m² of floor area.

Compact dimensions and the ability to operate with 11°C Δt system design conditions are key features of the new ADI-NOx ADI boilers. Three different versions are included in the range which covers a standard type fabricated from carbon steel and intended for the replacement market, plus two versions with stainless steel heat exchangers; a low temperature version which is tolerant to condensation and returns higher efficiencies, and for those applications that demand highest efficiency performance there is the condensing version.

Featuring a radiant premix burner fed with precisely pre-mixed gas and air, ADI-NOx ADI boilers have extremely low harmful emissions with NOx as low as 4.0mg/kWh at 0% O2. This low NOx concentration in the flue gases reduces the potential for damage to the environment caused by acid rain. In addition, extremely high seasonal efficiency can be achieved thanks to the modulating burner output with a high degree of turndown and the ability to create cascade/modular installations of up to 12 boilers.

Pisces Pressurisation Managers from MHS Boilers include Masterfill and Minifill units which are ideal for automatically topping up and maintaining the cold fill pressure in wet central heating and chilled water systems.

The Masterfill Managers are electronically controlled floor standing units available in single and twin pump versions with options of standard (up to 3.0 bar) or high pressure (up to 5.0 bar) fill pumps. The Minifill Managers are suitable for floor standing or wall mounting and are available in single or twin pump electronic versions. A single pump electro-mechanical version is also available, suitable for cold fill requirements up to 3.0 bar.

FOOD FOR THOUGHT AT NEW WAITROSE STORE

Wed, 14 Sep 2011 04:09:01 BST

Staff and customers at the new Waitrose store, Tottenham Court Road, London are benefitting from energy efficient and cool air in the summer, with effective heating in the winter, thanks to two Aquatop® T28 reversible water-to-water heat pumps and a 2,000 litre buffer vessel – all supplied by MHS Boilers, part of Elco Heating Solutions.

John Lewis Property Services specified the Aquatop® heat pumps to work from reclaimed heat generated via the store’s low carbon refrigeration system – the first installation of this type. Commenting on the project, Jim Burnett, Engineering Projects Manager, said: “We contacted MHS Boilers for advice because we needed to maximise efficiency, while being able to install a reliable and compatible system. The Aquatop® T28 water source heat pumps are ideally suited to the existing chiller system, ensuring appropriate year-round temperatures can be maintained.”

The two 28kW reversible heat pumps are well-equipped to power a combination of heating and active cooling through a cascade control system. They work compatibly with the existing chiller, through the buffer tank in the plant room. The heat pumps are able to reverse into cooling mode in the warmer months, rejecting heat via the store’s chiller system. While the same system uses the heat collected from the food cabinets on the chiller system throughout the winter months to provide a comfortable heated environment for shoppers and staff.

The Aquatop®(brine-water/water-waters) heat pumps from MHS Boilers are a new generation of heat pumps, using the ground and/or water traditionally as a free energy source to extract useable thermal heat. Aquatop® heat pumps can achieve particularly high supply temperatures, perfect for under-floor heating as well as for use in new (and in certain conditions even existing) wet system heating.

Aquatop® heat pumps can use energy from either water or geothermal sources. For low energy buildings you can choose from designs with 5.4kW of heat output. The extremely small power input of only 1.2kW is equivalent to the consumption of a small portable heater. For larger properties, MHS Boilers offers models with outputs up to 58.6kW in water-water application. Cascades of up to six units are possible (up to 351kW)

A range of seven compact models provide a system approach solution to heat pump installation. All components such as expansion vessels, circulation pumps, safety devices and electric elements are already built in, reducing installation time and space requirements. Pre-fitted and wired components also simplify installation plus the electric element can be used as an additional heat generator. Aquatop® heat pumps are designed to be easy to maintain as all components are designed to enable accessibility.

Aquatop® heat pumps work extremely quietly with sound emissions below 35dB(A). Measured from right beside the equipment, this value corresponds to around the noise level of a modern refrigerator. This quiet running is achieved by the compressor being two-way mounted and allowing it to oscillate freely. The housing of the heat pump is also well sound-proofed which minimises the transmission of sound through the air.

A NEW CHAPTER IN SUSTAINABLE HEATING

Fri, 03 Jun 2011 23:06:01 BST

MHS Boilers has supplied five Ultramax WM 120kW boilers, 18m² of Elco Auron® DF evacuated tube solar collectors and a twin coil 1,125 litre Inox-Maxi cylinder to the historic Montpellier Chapter Hotel in Cheltenham. The installation was part of the refurbishment of the Grade II listed building and the addition of a crescent-shaped wing extension.

Owned and operated by Chapter Hotels, the Montpellier Chapter Hotel is filled with British art, textiles and furniture. During the extension of the building, the hotel worked closely with the local heritage offices to ensure the design and building methods were sympathetic to the original Victorian house.

Ultramax WM

The Ultramax WMrange of wall mounted gas fired condensing boilers from MHS Boilers sets new benchmarks in power for appliances of their type. There are five models available with outputs of 45, 65, 85, 100 or 120KW. And the high outputs from these wall mounted boilers means that valuable floor space can be utilized for other purposes.

Arranged in a compact frame, the boiler uses a helical, stainless steel, tube-type heat exchanger with a matched modulating premix burner which can return efficiencies in excess of 109.5% net, with a turndown range of 5:1. All models can be room sealed if required and flued over considerable distances using either 2 x DN100 tubes or 100/150 concentric flue components. Environmental impact is kept to a minimum through very high efficiency and very low emissions from the clean burning premix combustion system.

In addition, frame mounted pre-assembled cascade configurations of the Ultramax WM are available in modules of two or three boilers – delivering outputs from 130kW up to a maximum 600kW.

Perfect for applications where walls are inaccessible or plant room is restricted, the frame mounted Ultramax WM cascade systems are designed to make installation and commissioning simple. Mounted on a steel frame, and with castors to make positioning easy, the frame mounted boilers are slim enough to fit through a standard width door and light enough to be manoeuvred by two people.

Auron® DF

Auron® DF direct flow vacuum tube solar collectors from Elco have been developed for both domestic hot water and heating support and have an extremely flexible and stable mounting system to make installation and alignment towards the sun simple. Together with the innovative hydraulic construction of the collector, every possible variation of roof, wall and floor positioning is available to the installer. By rotating the tubes
(between +/- 30°) the absorber plate can be aligned so that an optimal angle to solar radiation can be achieved.

The absorber plate is made of aluminium and has a highly selective coating. This surface is metallically bonded to a coaxial copper-tube system allowing the absorbed heat to be carried directly, and almost without loss, to the heat-carrying fluid of the solar energy system. The connection of the vacuum tubes to the manifold is via a conventional compression fitting with tube neck cover collars made of weather-proof synthetic material. The tube neck insulation is protected against environmental impact or bird pecking and the collar takes the strain off the glass-metal bonding to ensure a long lifespan for the vacuum tubes.

WOODEN IT BE NICE!

Mon, 18 Apr 2011 09:04:01 BST

Staff and pupils at Highcliffe Primary School in Guisborough, North Yorkshire, are benefitting from green and sustainable heating and hot water thanks to a 174kW Combustor C biomass boiler, supplied by MHS Boilers. Replacing three ageing gas-fired appliances, the installation is part of Redcar and Cleveland Council’s carbon management plan, which aims to reduce emissions by 40% by 2014.

Powered by wood pellets, the biomass boiler is automatically fuelled by a four-tonne hopper that is located in an adjacent storeroom. To act as a backup during downtime and periods of peak heating loads, a gas boiler system is connected via a plate heat exchanger to the installation with an ingenious extended shunt header system through underground pipework. And to further highlight the school’s commitment to sustainability, additional energy metering has been installed and excess ash from the pellets will be used as a fertilizer in the ground’s cultivation area.

The M&E consultants were Darlington based low carbon consultants Parsec Consulting Engineers. Commenting on MHS Boilers, Shaun Ackerley, Managing Director at Parsec Consulting Engineers, said: “Having worked with the team at MHS Boilers before, I knew the Combustor C would fit the project requirements including load/space allocation, and overall the project has proved to be a great success.” The contractor for the project was Geoffrey Robinson Ltd.

The Combustor series of biomass boilers is available with outputs from 30kW to 5.8MW. Smaller models in the range (C30 to the C100) are completely self-contained with an automated fuel delivery, de-ashing system, primary and secondary air fans, flue extraction fan, control panel and integral fuel hopper. Larger models have an externally mounted fuel delivery system.

As standard, all Combustor boilers are fitted with a durable underfeed burner which is composed of interchangeable elements making servicing simple. And for additional performance the elements are surrounded by high density Alumina Refractotherm® thermal insulation. All models are suitable for burning wood pellets or wood chips, while larger models are also capable of burning logs, corn and miscanthus – with options to generate either hot water or steam.

Sun shines for Flintshire School with MHS Boilers

Thu, 03 Feb 2011 10:02:01 GMT

A Flintshire primary school is achieving a 50% reduction in annual water heating costs thanks to the installation of its AURON® DF solar heating system from MHS Boilers.

The direct flow vacuum tube solar collectors have been installed on a pitched roof at Sandycroft School in Deeside, in conjunction with three floor-standing high performance MHS Ultramax PB 120kW boilers and an MHS Gemini 500 litre cylinder.

John Haime, Mechanical Services Design Engineer, Flintshire County Council said: “Flintshire County Council has an energy policy commitment to reduce carbon emissions through the installation of renewable technology. MHS Boilers and solar equipment were chosen on the basis of quality, best value and service back-up. We hope to achieve about 50% reduction on annual water heating costs.” In addition to the solar collectors, three MHS Ultramax PB 120kW boilers were installed to provide heating at Sandycroft School in six heating zones. Installer Mel Roberts of Buckley based Margden Heating said: “MHS products are cutting edge and user friendly - saving time and costs on installation.”

AURON® DF direct flow vacuum tube solar collectors haven been developed for both domestic hot water and heating support and have an extremely flexible and stable mounting system to make installation and alignment towards the sun simple. Together with the innovative hydraulic construction of the collector, every possible variation of roof, wall and floor positioning is available to the installer. By rotating the tubes (between +/- 30°) the absorber plate can be aligned so that an optimal angle to solar radiation can be achieved.

The connection of the vacuum tubes to the manifold is via a conventional compression fitting with tube neck cover collars made of weather-proof synthetic material. The tube neck insulation is protected against environmental impact or bird pecking and the collar takes the strain on the glass-metal bonding to ensure a long lifespan for the vacuum tubes.

The Ultramax PB range of floor standing boilers includes four models with outputs at 65, 85, 100 and 120kW. Fully condensing and fabricated from durable stainless steel, these appliances return efficiency up to 109.8% with a modulation range up to 6.8:1. Low Noise and low NOx emissions are also prime features of the Ultramax PB Boiler.

A comprehensive programmable boiler/system controller is included as standard which may be connected to intelligent room controls if desired. As an option, a low loss header can be incorporated into the boiler case as can a plate type heat exchanger to act as a separator to protect the boiler from the possible effects of dirt accumulation in older systems.

The flue connection allows for either room sealed or open type application with the capability for extensive lengths of flue to be accommodated. With the footprint area of the largest model at less than 0.51m², the Ultramax PB Boilers are frugal on their space requirement making them a perfect choice where space constraints are a key factor in product selection.

MHS Gemini HSC calorifiers are the ideal means to provide volume hot water in domestic, commercial and industrial applications. The Gemini 500ltr cylinder heats water for storage in a stainless steel vessel immersed within a primary tank.

The recently opened Highland Archive Centre in Inverness is enjoying sustainable heating and hot water thanks to four square metres of Auron® 20 DF solar panels, two Ultramax R606 504kW floor standing condensing boilers and a 300 litre Aquaprimo stainless steel water cylinder – all supplied by MHS Boilers. The installation was part of a Pound10.5 million investment by the Heritage Lottery Fund and The Highland Council.

The new centre includes an archive conservation unit, ceremony suite and modern office accommodation. There is also a dedicated family history centre to allow visitors to trace their family tree and cross reference it with the on site registration service. Specialist controls have been installed to safeguard all the stored records which had previously been held in Edinburgh.

Auron® DF is a direct flow-through vacuum tube collector which has been developed for both domestic hot water and back-up heating. It has an extremely flexible and stable mounting system to make alignment towards the sun simple. Together with the innovative hydraulic construction of the collector, every possible variation of roof, wall and floor positioning is available to the installer. By rotating the tubes the absorber plate can be aligned so that an optimal angle to the solar radiation can be achieved. The conversion of the sun’s rays into heat energy occurs via an absorber plate in an evacuated glass tube to ensure heat loss into the ambient air is negligible.

The absorber plate is made of aluminium and has a highly selective coating. This surface is metallically bonded to a coaxial copper-tube system allowing the absorbed heat to be carried directly to the heat-carrying fluid of the solar energy system. The connection of the vacuum tubes to the receiver is via a conventional compression fitting with their tube neck collars made of a weather-proof synthetic material. The tube neck insulation is protected against environmental impact or bird pecking with the collar taking the strain on the glass-metal bonding to ensure a long lifespan for the vacuum tubes.

The Ultramax R600 range of ultra-efficient high output, fully condensing, gas-fired, floor-standing boilers from MHS has best-in-class NOx emissions and efficiencies of up to 109%. The range comprises seven models with outputs from 150kW to 571kW and utilises a proven water-cooled, down-firing, premix burner system with an all stainless steel heat exchanger assembly. Ultramax R600 boilers have a NOx emission of less than 35mg/kWh (which easily exceeds the requirements for the best BREEAM score) and can return efficiencies of up to 109%. And for complete peace of mind, an optional annual service agreement from MHS Boilers extends their guarantee to 10 years – which means you can rest assured that all parts and labour for breakdown or servicing will be covered.

Ultramax R600 boilers are designed to pass through standard doors, with widths from 670mm and floor space is kept to a minimum with a footprint from as small as 0.74m². Each model is equipped with two return connections as standard, allowing high efficiency to be achieved when serving a mix of higher and lower system load circuit temperatures. Another standard feature is the option to utilise room sealed or open flue systems.

The Ultramax R600 is suitable for use in single boiler or multiple/cascade installations. If used singly MHS Boilers can supply plug and play optional extra low loss headers, and if being used as retrofit appliances onto aged systems, a matched boiler protection plate heat exchanger unit is available for total boiler isolation. The modulating burner system allows turndown ranging from 5:1 to 7:1 to return optimum efficiency at low system loads.

All Ultramax R600 boilers enjoy built-in reliability with all solid state controls and moving parts confined to the gas valve and fan, so there is little to wear through usage, plus all components are sensibly laid out within the uncluttered frame making maintenance a simple task. At just 59dbA, the Ultramax R600 range is extremely quiet - making them perfect for noise sensitive applications such as residential blocks, schools and libraries. The heat exchanger carries a 5 year guarantee.

Solar heating and condensing boilers at Holiday Inn, Birmingham

Tue, 12 Oct 2010 20:10:01 BST

The newly extended Holiday Inn at Birmingham Airport is enjoying green and sustainable heating and hot water thanks to the installation of 28 SOLARTRON® R 2.5 flat panel solar collectors as well as four Ultramax R607 floor standing condensing boilers from MHS Boilers. The installation also includes four 900 litre twin coil and three 3,000 litre single coil hot water cylinders from MHS.

The Holiday Inn, Birmingham Airport has recently undergone significant redevelopment adding an additional 103 bedrooms, as well as a conference area, meeting rooms, residents’ leisure facility, bar and restaurant and seating areas. To add to the complication of the redevelopment, all the work had to be carried out while maintaining services to the hotel at all times. The M&E consultant for the redevelopment was Faarup Associates, and Hydro Mechanical Services Ltd was the mechanical installation contractor. Brett Stokes and Peter Gammon from MHS Boilers worked closely with Sutton Coldfield-based Hydro Mechanical Services Ltd to ensure the system was fully integrated, as well as successful installation and commissioning. MHS also supplied the A-frames which house the SOLATRON® R 2.5 collectors.

SOLARTRON® R 2.5 flat panel solar collectors from Elco, are supplied exclusively in the UK by MHS Boilers. It is a low cost system which serves as back-up for domestic hot water generation and gets good energy returns the whole year round. At the heart of the SOLARTRON® R 2.5 collector is a full sheet copper absorber with a highly selective coating.

The size of the panels and the flexible mounting system make installation easy. The collectors can easily be mounted on tiled roofs and in several rows one above the other. A flat roof or ground mounting frame system is also available. The aluminium frame is supplied with temperature-constant mineral wool insulation to keep heat loss to a minimum. The solar safety glass used in SOLATRON® R 2.5 has a weatherproof EPDM sealing strip to ensure robust protection of the collector and an energy transmittance of >91%. This safety glass can also withstand the heaviest hailstorm.

The Ultramax R600 range of ultra-efficient high output, fully condensing, gas-fired, floor-standing boilers from MHS has best-in-class NOx emissions and efficiencies of up to 109%. The range comprises seven models with outputs from 150kW to 571kW and utilises a proven water-cooled, down-firing, premix burner system with an all stainless steel heat exchanger assembly.

Heat pumps bring sustainable heating to leading architects

Sat, 29 May 2010 19:05:01 BST

One of the UK’s leading architectural practices is enjoying renewable energy thanks to an innovative installation of two AQUATOP® T26 ground source heat pumps from MHS Boilers.

The two 26kW ground source heat pumps are used for trench heating at the Associated Architects practice at the iconic Mailbox building in the heart of Birmingham. Associated Architects have won over 20 RIBA awards for their projects.

The collectors for the heat pumps are located in the Grand Union Canal, which is adjacent to the building. The heat pumps use the waste heat in the canal which is generated from the surrounding buildings, and convert it into useable heating for the architectural practice.

The heating system was specified by Arup, Birmingham and installed by CA Sothers, a leading provider of mechanical and electrical installation and maintenance services. Martin Atkins, Contracts director, for C A Sothers commented: “The Aquatop T26 heat pumps were an ideal choice for our trench heating requirements, utilising the local canal water as primary heat source, their compact size suited the restricted plant space available and were easy to install within the spatial constraints made available to us.”

In addition to the two AQUATOP® T26 heat pumps, MHS Boilers also supplied a 400 litre buffer vessel.

AQUATOP® T are a new generation of heat pumps from ELCO, using the ground and/or water as a free energy source for comfortable thermal heat. AQUATOP® T heat pumps can achieve particularly high supply temperatures, perfect for underfloor heating as well as the use of new (and in certain conditions even existing) radiator heating.

AQUATOP® T heat pumps can use energy from either water or geothermal sources. For low energy buildings you can choose from designs with 5.4 kW of heat output. The extremely small power input of only 1.2 kW corresponds to the consumption of a small portable heater. For larger properties, ELCO offers models with up to 87.7 kW (113.6 kW = with water as the heat source).

A range of 7 compact models provide a system approach solution to heat pump installation. Compact models are available up to 18.5 kW. All components such as expansion vessels, circulation pumps, safety devices and electric elements are already built in reducing installation time and space requirements. Pre-fitted and wired components also simplify installation plus the electric element can be used as an additional heat generator. AQUATOP® T heat pumps are designed to be easy to maintain as all components are easily accessible.

AQUATOP® T heat pumps work extremely quietly. The sound emissions are below 35 dBA. Measured right beside the equipment, this value corresponds to around the noise level of a modern refrigerator. This whisper-quiet running is achieved because the compressor is two-way mounted and oscillates freely. The housing of the heat pump is also well sound-proofed. This minimizes the transmission of sound through the air.

Nexus district heating units from MHS Boilers at green student housing

Sat, 29 May 2010 18:05:01 BST

MHS Boilers has supplied 155 of its district heating Nexus units to a new student accommodation development at Tottenham Hale, London. Designed to achieve an excellent BREEAM rating and housing 687 students, the Pound53 million development was built by the UNITE Group, the UK’s leading developer and manager of student accommodation, and forms part of the wider Hale Village regeneration scheme.

The Nexus units are bespoke variants of the standard IS and Monotherm from MHS Boilers and are connected to the development’s onsite combined heat and power (CHP) plant. There are four different types of Nexus at the building - a mixture of heating and hot water units as well as hot water only units for the laundry areas. The heating and hot water units are surface-mounted direct IS models but have higher than standard outputs of up to 75kW. In the laundry areas there are two versions of the Monotherm unit with outputs of up to 58kW. The units were commissioned by engineers from MHS Boilers and the building contractor.

The building, which was completed in September 2009, comprises of four accommodation blocks, built with upper and lower landscaped courtyards with a colonnade providing the link between them. The students have a choice of well-built, contemporary apartments comprising large flats for shared living, as well as studio units and one bedroom apartments.   There are also communal areas for socialising, laundry facilities, bike storage and vending machines.

In order to achieve its excellent rating from BREEAM, the building used extensive off-site manufacturing techniques and has incorporated rainwater harvesting for WC flushing, a high degree of thermal insulation and levels of green roofs to increase bio-diversity. As the first development to complete on site at Hale Village, the accommodation is the first building to tap into the onsite CHP plant for both hot water and electricity - significantly reducing CO2 emissions.

With the growing popularity of district, network or community heating systems, MHS Boilers has developed a range of innovative heat interface units which provide the link between a community heating system and a dwelling or small business unit. Whether the requirement is for a direct type unit or an indirect unit, for build-into-the-wall or for wall-hanging, with or without heat or water metering or with connections top/bottom or all on one plane – MHS Boilers has a comprehensive solution with Nexus. Chilled water metering is also possible for developments where cooling from a central source is also provided. MHS Boilers can also provide the central boiler plant with gas condensing boilers available up to 1.9MW each. And much larger outputs are available as multiple boiler installations.

Overview of model types

The Nexus range is split into build-into-the wall and wall hanging types and then subdivided further. Brief explanations are listed:

•   Nexus Diatech Units are build-into-the wall versions and are useful where the dwellings do not have a dedicated cupboard or enclosure for the siting of the heat interface unit.
•   Nexus Futura Units are fully cased wall mounted types with lockable doors/access panels.
•   LF versions are available in both Diatech and Futura types and these variants are specifically designed to operate with lower central system flow and return temperatures which are ideal for realizing better efficiency from the use of condensing boilers as the community heat source.
•   Bitherm types indicate that the unit is an indirect heating version and includes a heat exchanger for complete hydraulic separation of the dwelling’s central heating circuit from the community system.
•   Conter Zone Distribution Units are build-into-the-wall type units which can distribute and meter the supply of any or all of the following services: central generated heating, centrally generated hot water, cold water or chilled water.

Special Units
Although the Nexus range is very comprehensive and most requirements can be satisfied from the extensive range of standard models, MHS Boilers can produce special units to meet specific requirements such as larger capacities or the inclusion of underfloor heating coil manifolds etc.

Meters
•   Heat Meter: CE marked Turbine type 1.5m3/h flow, class C, with liquid crystal display and long life battery. Upon request, equipped with data transmission cable for centralised consumption data reading (M-Bus).
•   Water meters: CE marked turbine volume flow meter 1.5m3/h flow.

ULTRAMAX PB FROM MHS BOILERS AT HISTORIC NAVAL CHURCH

Sat, 29 May 2010 13:05:01 BST

Two highly-efficient 120kW Ultramax PB condensing boilers have been installed at a historic naval dockyard church in Chatham as part of a new central heating system that is expected to reduce gas usage by more than 20%.

The former Pembroke Barracks naval church is a listed building completed in 1906 and is now known as the St. George's Centre. Owned by Medway Council, it houses 94 stained glass windows as well as memorial plaques to the fallen of both world wars.

Medway Council needed to replace the centre’s ageing cast iron atmospheric boilers with an efficient condensing model while maintaining the existing pipework. Therefore the crucial factor in the selection of MHS Ultramax PB condensing boilers for the centre was the option of a built-in plate heat exchanger to separate the boiler from the primary heating circuit.

John Richardson of Medway Council’s Design and Surveying Team, who specified the MHS Ultramax PB 120 boilers, commented: “Ultramax PB boilers suited our requirements at the centre - having a very old heating system and large pipework with the possibility of accumulated debris. It made sense to divorce the system water from the boiler by means of the heat exchanger.”

Dave Callcott of MHS Boilers designed the new heating system for the centre and overcame the issues of special flueing requirements in a listed building with boilers located in the basement. He said: “As the former chapel is a listed building the existing chimney had to be used. To ensure that the products of condensation did not cause damage, it was lined with PPS plastic flexible liners connected to each boiler. Installing this type of material was possible due to the low flue gas temperatures of the extremely efficient Ultramax PB condensing boiler.”

A wide variety of flue connections are available for Ultramax PB boilers allowing for either room sealed or open applications and extensive lengths of flue. Dave Arnott of installers J & P Arnott of Gravesend commented: “As an old church there was restricted access, but the units fitted well into the basement room and the flue liners enabled us to use the existing chimney.”

Control of the Centre’s Ultramax PB boilers is via a matched MHS RVA 47 cascade unit that also provides direct on boiler weather compensation and time control.

The Ultramax PB range of floor standing boilers includes four models with outputs at 65, 85, 100 and 120kW. Fully condensing and fabricated from durable stainless steel, these appliances return efficiency up to 109.8% with a modulation range up to 6.8:1. Low Noise and low NOx emissions are also prime features of the Ultramax PB Boiler.

A comprehensive programmable boiler/system controller is included as standard which may be connected to intelligent room controls if desired. As an option, a low loss header can be incorporated into the boiler case as can a plate type heat exchanger to act as a separator to protect the boiler from the possible effects of dirt accumulation in older systems.

The flue connection allows for either room sealed or open type application with the capability for extensive lengths of flue to be accommodated. With the footprint area of the largest model at less than 0.51m2, the Ultramax PB Boilers are frugal on their space requirement making them a perfect choice where space constraints are a key factor in product selection.

Sun shines on MHS Boilers at ÂPound4.5 million fire station

Fri, 25 Sep 2009 14:09:01 BST

MHS Boilers has recently supplied 24m²of AURON® DF evacuated tube solar collectors and a 1380 litre solar buffer vessel, along with an Ultramax 85kW wall-mounted condensing boiler and pressurisation manager to the new Rayleigh Weir fire station in Essex.

With sustainability and energy efficiency at the heart of the fire station’s design, the solar thermal system complements a ground source heat pump and innovative design to create a very green building.

The Pound4.5 million building is being built by Mullaley and Company, designed and project managed by Hunters and incorporates a single-storey four-bay garage, a training tower, and a two-storey administration and accommodation block. Basildon and Castle Point Community Command will also be based there, providing fire safety and administrative functions. The station will also provide a home for youth schemes to help with the behaviour of youngsters who have had difficulties at school or have been involved in crime.

The solar thermal installation was completed by MHS Boilers’ preferred installation company TCS Group. TCS Group’s Technical Sales Director, Simon Simmons said: “The evacuated tubes from MHS Boilers were very easy to install, and thanks to their clever design, can be oriented to provide the optimum angle to the sun. The free energy generated by the sun will add to the already strong green credentials of this innovative building.”

AURON® DF direct flow vacuum tube solar collectors haven been developed for both domestic hot water and heating support and have an extremely flexible and stable mounting system to make installation and alignment towards the sun simple.

Together with the innovative hydraulic construction of the collector, every possible variation of roof, wall and floor positioning is available to the installer. By rotating the tubes (between +/- 30°) the absorber plate can be aligned so that an optimal angle to solar radiation can be achieved.

The absorber plate is made of aluminium and has a highly selective coating. This surface is metallically bonded to a coaxial copper-tube system allowing the absorbed heat to be carried directly and almost without loss to the heat-carrying fluid of the solar energy system.

The connection of the vacuum tubes to the manifold is via a conventional compression fitting with tube neck cover collars made of weather-proof synthetic material. The tube neck insulation is protected against environmental impact or bird pecking and the collar takes the strain on the glass-metal bonding to ensure a long lifespan for the vacuum tubes.

The Ultramax WM range of wall mounted gas fired condensing boilers set new bench marks in power for appliances of their type; with five models available at 45, 65, 85, 100 and 120KW. With such output available for wall mounting, valuable floor space can be utilized for other purposes keeping plant room space requirement within a building to a maximum. Arranged in a compact and uncluttered frame, the boiler utilizes the well proven helical stainless steel tube type heat exchanger and this with its matched modulating premix burner can return efficiency in excess of 109.5% net with a turndown range of 5:1. All models may be room sealed if required and can be flued over considerable distances using either 2 x DN100 tubes or 100/150 concentric flue components. Environmental impact is kept to a minimum through very high efficiency and very low emission from the clean burning premix combustion system.

Solar success for MHS at award winning Welsh college

Fri, 25 Sep 2009 11:09:01 BST

MHS Boilers has supplied six square metres of its AURON® DF evacuated solar tubes and two Ultramax 45 wall-mounted condensing boilers to the new Centre for Art and Design Technology at Coleg Morgannwg, Nantgarw, South Wales.

Opened by the Deputy Minister for Skills, John Griffiths AM, the Centre was recently awarded a prestigious BREEAM 2009 Award as one of the most sustainable and energy efficient buildings in Wales. It is BREEAM Excellent-rated with a score of 74.39%, uses renewable energy technology, Green Guide A-rated materials and has a five year biodiversity management plan to enhance the ecological value of the site.

The multi-million pound centre has been designed over three floors and is fully equipped for the teaching of art and design. It includes design and fashion/costume studios, a specialist 3D workshop, screen printing facilities and ICT areas equipped with the latest technology as well as a photographic studio and graphic art studio, all equipped with industry standard equipment.

The solar collector was sited on the facade of the building to maximise absorption of the sun’s rays when it is lower in the sky. The solar installation was specified by Corporate Consult (M&E) Services, Neath and installed by CMB Engineering Services and Natural Power Wales. Kelvin Lewis of Corporate Consult Services said “I was very pleased with the advice, service and technical backup received from MHS Boilers”.

The project was completed in Autumn 2008.

AURON® DF direct flow-through vacuum tube collectors from MHS Boilers have been developed for both domestic hot water and back-up heating. They have an extremely flexible and stable mounting system to make alignment towards the sun simple.

Together with the innovative hydraulic construction of the collectors, every possible variation of roof, wall and floor positioning is available to the installer. By rotating the tubes the absorber plate can be so aligned that an optimal angle to the solar radiation can be achieved. The conversion of the sun’s rays into heat energy occurs via an absorber plate in an evacuated glass tube to ensure heat loss into the ambient air is almost completely prevented.

The absorber plate is made of aluminium and has a highly selective coating. This surface is metallically bonded to a coaxial copper-tube system. In this system, the absorbed heat is carried directly and almost without loss to the heat-carrying fluid of the solar energy system.

The Ultramax WM range of wall mounted gas fired condensing boilers set new bench marks in power for appliances of their type; with five models available at 45, 65, 85, 100 and 120KW. With such output available for wall mounting, valuable floor space can be utilized for other purposes keeping plant room space requirement within a building to a minimum.

Arranged in a compact and uncluttered frame, the boiler utilizes the well proven helical stainless steel tube type heat exchanger and this with its matched modulating premix burner can return efficiency in excess of 109.5% net with a turndown range of 5:1. All models may be room sealed if required and can be flued over considerable distances using either using either parallel tubes or concentric flue tubes components.

IN AT THE DEEP END: SWIMMING POOL BOILERS AND WATER HEATERS FROM MHS

Wed, 08 Jul 2009 14:07:01 BST

MHS Boilers has launched a new range of direct gas-fired swimming pool condensing boilers and water heaters. The Ultramax 600 range are sister products to the company’s hugely successful and popular R600 condensing gas-fired central heating boilers.

There are three types of water heater in the range – swimming pool boilers, water heaters and bypass water heaters. With seven models in each of the types, and outputs up to 571kW, there is a model for most light industrial or commercial hot water or swimming pool applications. As you would expect from the Ultramax stable of boilers, these appliances are class-leading in both power and efficiency, with low emissions and power to weight/size ratios.

Utilising a heat exchanger and water ways that are fabricated totally from high grade stainless steel, these state-of-the-art heaters are designed to operate with direct water or swimming pool water without the need for intermediate heat exchangers or hydraulic separation.

High combustion efficiency is achieved thanks to the water-cooled, down-firing, premix burner system arrangement and the Ultramax 600 range also has extremely low environmental impact with NOx emissions at just 35mg/kWh @ 0% O2.

THE RANGE:

Swimming Pool Boiler (Ultramax 600SP)

With seven models with outputs from 142kW up to 539kW and the possibility to be used in cascade arrangements of up to eight boilers; most pool sizes or complexes can be accommodated from this extensive range.

Water Heaters (Ultramax 600WH)

The Ultramax 600WH range offers outputs at 142, 190, 237, 285, 380, 475 and 539kW which may be partnered with buffer vessel capacity consistent with the needs of the specific application, to provide a tailored hot water generation system.

Bypass Water Heaters (Ultramax 600WHB)

Available in the same range as the 600WH models, the Bypass versions allow high temperature rises to be achieved for applications such as process hot water generation or for use without buffer storage capacity.

Euron from MHS: Compact, Efficient, Easy to Install & Maintain

Fri, 08 May 2009 12:05:01 BST

MHS Boilers has launched a new range of wall-mounted gas-fired condensing boilers.

Including both system and combination boilers, the Euron® utilises a proven helical stainless steel tube heat exchanger with a fully modulating radiant premix burner for high efficiency, low emissions and controllability.

There are two system boilers in the Euron® range – with 24kW and 30kW outputs, and a 30kW combination boiler. The combination boiler model will deliver instantaneous hot water up to 11.91l/m raised through 35°C. All appliances in the range can be room-sealed using small diameter flue components and can be used singly or in multiple groups under the control of a cascade manager.

Each boiler is supplied with a wall mounting bracket that is complete with heating circuit flow and return isolation valves, gas valve, water supply isolation valve (combi only) and preformed copper tube connection tails.

Euron® boilers incorporate a metal fibre sheathed radiant premix burner which modulates through a nominal turndown range of 4:1. The combustion system is extremely efficient and thanks to the premix principle have very low emissions. NOx emissions are reduced further by the radiant effect of the burner surface, which avoids the nitrogen content of the air entrained for combustion being excessively heated and oxidized – giving the Euron® a NOx Class 5 rating.

Included with each boiler is an outside air temperature sensor to allow weather variable flow temperatures to be delivered to the heating system. This feature, if utilised, can enhance the comfort of the heating system and contribute significantly to the operational efficiency of the Euron®.

Euron® boilers have an over-pressure of up to 110 Pa at the flue connection allowing the appliances to be exhausted over considerable distances with or without a room sealed air supply. Low diameter polypropylene (PP plastic) material may be used and an extensive range of flue components, wall and roof terminals are available.

Additional options include a programmable modulating room unit (QAA73) to match the boiler output to room demand as well as providing optimum comfort control over the room temperature. Hot water supply programming is also possible from the room unit, plus the ability to retrieve system status information.

For multiple boiler installations of up to 12 modules, a cascade manager (RVA47) is available which may interfaced with a room unit if required. In addition various control expansion clip-in modules may be added to a single boiler to allow enhanced zone control and or accept analogue control inputs.

Advanced MHS Ultramax boiler technology for luxury hotel

Thu, 16 Apr 2009 12:04:01 BST

With the warmth and comfort of guests a top priority, three high performance MHS Ultramax PB condensing boilers have been installed at the luxury 60 bed Cooden Beach Hotel in Bexhill.

Utilising advanced MHS separator technology the boilers have been fitted with plate heat exchangers to enable the new system to achieve maximum efficiency. Following installation, energy savings of between 15 and 20% are anticipated for the hotel along with a significant reduction in carbon emissions.

The Ultramax boilers replaced long serving MHS Regency GBS atmospheric units which were more than 15 years old. Installation of plate heat exchangers in the new boilers successfully overcame the problem of switching from an open vented to a pressurised system. Systemdesigner Dave Callcott of MHS Boilers said: “By installing the plate heat exchangers in the new boilers the problem of the two types of systems was overcome. The new boilers were fitted in an adjacent store room while the original boilers were still running. A concentric (room sealed) flue system facilitated this type of operation. The MHS control package ensured that the boiler output matched the system requirements and enhanced the boiler seasonal efficiency of 95%.”

Contractor for installation of the boilers was Mechanical and Plumbing Services of St Leonards on Sea.

Mark Dengate of Mechanical and Plumbing Services said: “I like the product, it looks good, is easy to install and does exactly what it says on the paperwork. I will definitely be recommending MHS boilers for future contracts. The back-up from MHS was also good – when we had a question they came down and sorted it out for us immediately.”

With MHS Ultramax PB boilers a plate type heat exchanger option kit can easily be incorporated into the boiler case to act as a barrier, protecting it from the effects of dirt accumulation in older systems. As an alternative for new installations, a low loss header kit option can be accommodated within the boiler’s smart casing.

MHS Ultramax PB boilers are available in four models (65kW, 85 kW, 100kW and 120kW). A small footprint of less than 0.51 m2, makes these units an ideal choice where boiler space is at a premium. However, its compact size belies its power and efficiency with a pre-mix modulating burner that gives a return efficiency of 109.8% and a modulation range up to 6:8:1. All models can be flued over considerable distances either 2 x DN80 tubes or 2 x DN100 tubes dependant upon model. Concentric flue components may also be used with sizes at 80/125 or 100/150 dependant upon model. Environmental impact is kept to a minimum through very high efficiency and very low emissions from the clean burning premix combustion system. A comprehensive programmable boiler/system controller is included as standard, which allows connection to intelligent room controls if required.

James Kimber, owner of the Cooden Beach Hotel, commented: “The new MHS Ultramax boilers have performed excellently since installation. With fuel costs on the increase the energy savings they bring will be most welcome, as will the opportunity to enhance our environmental credentials.”

Xpressflo from MHS Boilers: Seriously powerful condensing hot water generat

Wed, 15 Oct 2008 14:10:01 BST

MHS Boilers has launched a new range of hot water generators which deliver high volumes of hot water and consistently high efficiency thanks to their inventive design. A gas-fired, low-emission, condensing unit is used in conjunction with stainless steel storage vessels of 300 or 500 litres.

Both units have a powerful heat input of 60kW to deliver up to 650 litres of water raised through 50ºC to be drawn in just 10 minutes. Even though the primary function of Xpressflo is to deliver lots of efficiently generated hot water, they can also deliver a central heating service of up to 43kW whenever there is no hot water load.

The Xpressflo uses an innovative cold feed connection into its storage vessel to maximize its potential to operate in condensing mode. The cold feed is positioned to inject the cold refilling water towards the intake of the tubing system which delivers the water into the condensing heating unit.

This ensures that the lowest possible water temperature at any given time is passed over the condensing heat exchanger - cooling the exhaust gases to below dewpoint under almost all operating conditions. Additionally, the Xpressflo is quick to respond by using a reverse of the cold feed principle. Hot water is injected toward the outflow connection on the storage vessel, allowing the unit to deliver hot water in almost instantaneous way.

Standard features include stainless steel storage vessel and condensing heating unit, room sealed flue options using 80/12mm concentric flue components (with either horizontal or vertical terminal sets) or a parallel 2 x 80mm flue/air supply tubes and a fully modulating premix burner with 5:4:1turndown for optimum load matching and fuel economy.

Naturally low emissions are a priority and they are inherent with the burner system and the operational conditions. The Xpressflo hot water generator emits less than 15mg/kWh NOx @ 0% O2 Class 5) further adding to the appliance's green credentials and meeting the criteria for the best possible BREEAM rating.

MHS Ultramax boilers make their mark in the City

Tue, 16 Sep 2008 15:09:01 BST

Four MHS Ultramax R3604 boilers have been installed at Watermark Place, a fourteen floor, 42,350m2 commercial office development. The development also creates one of the large public realms north of the Thames in the City of London.

Construction of the landmark city building is still underway. When completed it is expected to notch up an ‘excellent’ BREEAM environmental rating aided by the latest environmentally and energy efficient MHS Ultramax R3600 series condensing boilers.

The energy efficient Ultramax boilers will serve the building’s main fan coil units, underfloor heating, radiators, perimeter heating and air handling units.

Specifier Mark Terndrup of Waterman Building Services commented: “Their low NOx emissions were vital in the choice of Ultramax R3604 units for Watermark Place. Low NOx emissions will be an important contributory factor in the building achieving an excellent BREEAM environmental rating.”

Mr Tendrup added: “We have a long standing relationship with MHS Boilers based on the ability of their products to meet both the technical requirements and economic conditions specified in our high value contracts.”

Ultramax R3600 SB appliances offer important space saving and low weight loading. With output to floor space of around 380kW/m² and power to weight nominally at 0.98kW/kg; compared with a similar output conventional shell and tube boiler which is more than twice the weight and approximately 14 kW lower output per square metre of footprint (not including the space needed for the burner).

Commenting on space saving achieved Gary Edgar, Projects Director N G Bailey said: “The compact arrangement of the boilers was the best solution due to co-ordination restrictions within the basement boiler house.”

The down-firing water cooled pre-mix burner arrangement of the boilers not only ensures maximum combustion efficiency; the NOx emissions of both the 3600 and 3400 SB boiler series are also Class five with the R3600SB models emitting just 11.5mg/kWh, easily exceeding the requirements for the best BREEAM NOx emission rating

Manufactured using all stainless steel heat exchanger components; robustness and longevity is inherent in the R3400/R3600SB series of boilers. Modulating down firing premix burners with unique water cooling to the combustion system returns controllability with efficiency and clean burning. With a power range from nominally 660kW to 1.9MW and the possibility to use up to eight boilers in a cascade arrangement; the Ultramax R3400/R3600SB Boilers are ideally suitable for larger commercial heating applications such as office developments, secondary schools, retail centres, hotels, residential blocks or community heating projects.

London mansion blocks fitted with MHS Nexus units

Mon, 15 Sep 2008 15:09:01 BST

Five Victorian mansion blocks of flats in central London dating back to the 1880s are being fitted with 84 MHS Nexus units as part of a multi-million pound refurbishment and modernization project by St Pancras Housing (SPH Housing).

Nexus units are contributing to the overall enhanced energy efficiency of the Holborn mansion buildings to the extent that the SAP rating (the government measure for energy efficiency) per flat is almost doubling from 26 to 49 - above average for existing homes in England. The refurbishment project will also take the Holborn mansions way beyond the government’s Decent Homes standard to a Decent Homes ‘Plus’.

The MHS Nexus is a heat/hot water Interface unit that allows metered service to be provided to multi - dwelling developments such as blocks of flats and district heating schemes. At Holborn Mansions Nexus substation units will supply heating and hot water to social housing tenants, replacing an inefficient, mixed arrangement of heating and hot water systems which are being consolidated into a central boiler plant with Nexus substations in each flat.

Specifying consultant Graham Jarman Associate director of Hannaford Upright selected the Nexus units as a solution to providing the equivalent of individual combination boiler services eliminating the requirement for mains gas risers and perimeter flues within the mansion buildings. He commented: “The neat appearance of the units, with no gas pipes and no flue to be installed makes Nexus units especially attractive within the confines of a flat where space saving is at a premium. The ability to remotely monitor individual energy usage in each dwelling is another significant advantage of the Nexus system.”

With a Nexus substation system heat is provided from a central source; a central boiler plant or CHP system and is distributed via a simple LTHW loop circuit around the entire building or development. A Nexus unit is installed in each dwelling and a flow and return connection is made into the centralised circulation system to provide the primary heat to the Nexus. The heating circuit of the individual dwelling is also connected, plus a boosted cold water supply and a hot water outlet.

The unit is supplied complete with a programmable room thermostat to allow for time and room temperature control over the heating system. As an integral part of the internal temperature control system of the Nexus; a motorised blending valve is utilised and this may, if required, provide weather compensated water temperature to the heating system – an outside air temperature sensor is supplied as standard. Domestic hot water is developed instantaneously via a compact brazed plate heat exchanger. The energy consumption of the dwelling is monitored and recorded by an inbuilt heat meter from Siemens Building Technologies. The output of the Nexus is up to 20.8kW for central heating and 40.7kW for domestic hot water.

Installing Nexus units is a relatively simple job with no gas present. The built-in heat meter records energy use for each unit and enables the building owner to charge accordingly. The meter can be accessed remotely and with appropriate control solutions can send energy usage data direct to the energy supplier. Its flexibility means Nexus units can be used in conjunction with a variety of central boiler plant types – oil, gas, CHP or biomass.

Five Holborn mansions – Braunton, Bideford, Barnstaple, Dulverton and Dawlish are to be transformed over the next two years into highly sustainable eco-buildings with MHS Nexus units at the heart of the project.

City offices achieve excellent BREEAM rating with MHS

Fri, 27 Jun 2008 16:06:01 BST

The latest specification MHS Ultramax R3600SB boilers have been installed at a major central London office development in high and low temperature circuits which meet the 260,000sq ft building’s heating and energy management system needs.

Constructed by Skanska, the ultra modern office development at One Kingdom Street is the latest addition to the Paddington Central scheme, a new mixed use area that has become established as one of London's premier business, residential, healthcare and leisure destinations.

Five Ultramax R3600SB stainless steel premix gas fired condensing boilers, with a total output of nearly 4.5MW, have been installed at One Kingdom Street which has achieved outstanding green credentials with an ‘Excellent’ BREEAM environmental rating.

The down-firing water cooled pre-mix burner arrangement of the boilers not only ensures maximum combustion efficiency; the NOx emissions of both the 3400 and 3600SB boiler series are Class five with the R3600SB models emitting just 11.5mg/kWh, easily exceeding the requirements for the best BREEAM NOx emission rating.

Installation space saving has been achieved in a bespoke prefabricated boiler room thanks to the small footprint of the boilers which combine low weight, compact dimensions and low emissions. Up to 1895kW is obtainable from a single unit.

Three R3605 SB units have been installed to serve the building’s low water temperature circuit that includes air handling plant, main fan coil units and warm air heating for the floor space. Two smaller Ultramax R3600SB units serve a circuit operating at a flow temperature of 80°C serving hot water calorifiers and radiators.

Ultramax R3600 SB series boilers deliver an output to floor space of around 380kW/m² and power to weight nominally at 0.98kW/kg; compared with a similar output conventional shell and tube boiler which is more than twice the weight and approximately 14 kW lower output per square metre of footprint (not including the space needed for the burner).

Specifying consultant, Martin McLaughlin of Faber Maunsell said: “The low NOx emissions of Ultramax boilers were essential in achieving the building’s excellent BREEAM rating. Space saving efficiencies in the plant room were also achieved through the compact size of the units.”

Manufactured using all stainless steel heat exchanger components; robustness and longevity is inherent in the R3400/R3600SB series of boilers. Modulating down firing premix burners with unique water cooling to the combustion system returns controllability with efficiency and clean burning. Ultramax R3400/R3600SB Boilers are ideally suited to larger commercial heating applications thanks to outputs of between 660kW and 1.9MW and the possibility to use up to eight boilers in a cascade arrangement.

MHS Boilers turns up the heat for the Land Registry

Wed, 23 Apr 2008 09:04:01 BST

Two MHS Ultramax 278 floor standing, gas-fired condensing boilers and Tudor NHREV high performance water heaters will be at the heart of a major refurbishment of the imposing Land Registry building in Lincoln Inn Fields.

The 1913 building is the headquarters of the Government organisation which records ownership rights of freehold and leasehold properties in the UK, and contains the largest property database in Europe. Refurbishment will include replacement of the existing inefficient heating and water services system.

MHS Ultramax 278 kW boilers were selected for their compact footprint which allows for maximum site flexibility and low NOx emissions, a crucial factor for a Government run organisation needing to demonstrate the very highest environmental credentials.

MHS is also providing the new hot water system in the Land Registry canteen with two room sealed flue, direct gas-fired, high performance Tudor NHREV18 water heaters offering a compact footprint size for ease of installation.

In keeping with the style of the historic building, traditional MHS cast iron radiators are being installed. The comprehensive range of MHS traditional style radiators make it possible to purchase all heating products for the Land Registry project from one supplier.

Ultramax is a range of gas–fired condensing, high efficiency, low NOx boilers, specially designed for today’s commercial needs of high output with clean emissions, all from a compact unit. Engineered for quick agasnd easy maintenance without the need for specialist tools and a small foot print for greater siting flexibility, Ultramax boilers incorporate a wealth of standard operating features to provide optimum efficiency and low running costs.

Ultramax boilers utilise a downward firing, water cooled, pre-mix burner that is fully variable from 25% to 100% which, combined with precise gas to air mixing, results in ultra clean emissions in the range of < 43 mg/kWh NOx (30ppm DAF), < 19 mg/kWh CO (15 ppm DAF). This coupled with direct-on-boiler weather compensation allows efficiencies in excess of 107% net to be achieved.

The Tudor NHREV range of high efficiency hot water heaters, utilises high quality steel bodies with high quality enamel lining and a powered active anode system for cathodic internal corrosion protection. This combination assures longevity and reliability regardless of the nature of the water supply.

Each Tudor NHREV appliance is equipped with a low NOX emission metal fibre clad, premix burner with fully automatic spark ignition and flame ionisation safety protection. User adjustable temperature control, manual reset high limit protection and combustion fan safety interlock are also included as standard features.

The consulting specifier for the project is Troup Bywaters & Anders and the installing contractor is Cofathec Heatsave.

District Heating Made Easy at Catherine Mill

Thu, 06 Sep 2007 12:09:01 BST

Catherine Mill in Whitehaven, Cumbria is enjoying district heating thanks to 36 Nexus units from MHS Boilers. The system supplies heating and hot water to 31 flats, offices and communal areas at the West Cumbria Area Office of the Two Castles Housing Association.

It is also the first installation of its kind in the UK to communicate the occupant’s energy use direct from the Nexus metering system via a modem to British Gas in Manchester for billing.

The Nexus provides both heating and instantaneous hot water (up to 19 litres per minute). Provided with each unit, is a simple to use programmable room thermostat which allows comfort, economy and frost protection temperatures to be set to the users time scheduling requirements. Each Nexus unit draws heat from the central boiler plant via a simple low temperature hot water loop and from that point on provides all the functions of a combi boiler.

The Nexus features a state of the art Siemens Building Technologies heat meter, which is connected via an M-Bus system to the energy supplier's offices for remote energy consumption monitoring and billing purposes.

The Nexus units replaced old thermal stores at Catherine Mill, which were insufficiently insulated and caused problems with their thermostatic control. By replacing them, the central boiler plant could be retained and the end-users could still benefit from instantaneous hot water at all times and controllable central heating when needed.

The Nexus units are smaller than the original thermal stores and therefore much needed cupboard space has been freed up for the occupiers.

The system was designed and specified by Ken Wilkinson and Peter James of Wilkinson James Partnership Ltd in Workington, Cumbria. Ken Wilkinson said: “The units were simple to install and we were able to keep the existing plant room and equipment, which meant there was minimum disruption to residents.”

The link up of the Siemens metering systems via the modem to the British Gas computer system was completed by Blaydon-on-Tyne-based Bell Control Solutions Ltd and managed by Project Manager Phil Bell. The architect for the project was Day Cummins Ltd of Cockermouth.

Catherine Mill, which used to be known as Barrack Mill is a Grade II listed building. It was built in 1890 to manufacture linen and was occupied by the Royal Cumberland Militia in 1857. It was later used as a flour mill, carpet and clothing factory and warehouse. Catherine Mill was restored and refurbished in 1992 for the Two Castles Housing Association with assistance from English Heritage, Copland Borough Council and the Housing Corporation.

MHS Boilers launches biomass commercial boilers

Wed, 01 Aug 2007 12:08:01 BST

Leading boiler supplier MHS Boilers has augmented its range of renewable energy products with a full range of large scale commercial biomass boilers. Perfect for district heating, commercial and local authority applications, the boilers are available from 25kW – 1MW..

Working in partnership with wood heating specialist Econergy Ltd, MHS Boilers is able to provide a full advice, installation and after care package. The wood chip or pellet boilers are fully modulating to 30% at up to 95% efficiency and are tolerant of wet low grade fuel.

The biomass boilers are fully automatic from the feeder, ignition and boiler cleaner to the disposal of ash. The boilers are managed with electronic and power saving control systems which ensure top fuel efficiency and maximum output. The range is suitable for a wide range of fuels – pellet, wood chips or logs, some without major conversion, and is compatible with traditional heating systems as well as heat pumps and solar hot water.

MHS Boilers can offer full scoping of projects with outline proposals, payback and emission reduction figures, as well as full design including specification, schematic diagrams and controls. Full service backup, extended guarantees and servicing contracts are also available.

MHS Boilers goes into Battle for visitor centre

Thu, 31 May 2007 01:05:01 BST

Two Ultramax WM100 wall mounted high-performance condensing boilers from MHS have been installed at a new visitor centre at Battle Abbey, East Sussex.

The visitor centre provides orientation and interpretation facilities, new visitor toilets and a café, together with new landscaping within the Abbey grounds. The building follows the slope of the site and is built from Sussex Sandstone, brick and stainless steel and has a fully glazed façade in the café.

The visitor centre, which is run by English Heritage, has a building management system to ensure the most efficient use of energy. The boilers were specified for their high performance – 95% gross seasonal efficiencies – as well as for their ability to modulate their output according to the system load. Additionally, each Ultramax WM100 boiler delivers a high output of 100kW, and thanks to their ease of installation and range of flue options, were able to fit in a confined boiler plant room.

Battle Abbey was founded in 1070 when William the Conqueror vowed to build a monastery at Battle as an act of penance for the violence of the Conquest. The high altar was placed on the spot where it was said that King Harold died.

The installation was specified by Dominic Shortland of GDA Associates, Brenchley, Kent and completed by BSW Heating of Haywards Heath, Sussex.

The Ultramax WM range of wall mounted gas fired condensing boilers set a new benchmark in power for appliances of their type. There are five models available at 45kW, 65kW, 85kW, 100kW and 120kW. Thanks to their high outputs and wall mounting, plant room space can be maximised and valuable floor space used for other purposes. The three boilers with the smaller outputs are supplied with integral modulating speed primary pumps.

Engineered in a compact and uncluttered frame, the boiler utilises the well proven helical stainless steel tube type heat exchanger and coupled with its matched modulating premix burner can return efficiency in excess of 109.5% net with a turndown range of up to 7:1 dependant upon model.. All models can be room sealed if required and flued over considerable distances either 2 x DN80 tubes or 2 x DN100 tubes dependant upon model. Concentric flue components may also be used with sizes at 80/125 or 100/150 dependant upon model. Environmental impact is kept to a minimum through very high efficiency and very low emissions from the clean burning premix combustion system.

MHS at the heart of the Brittas Empire

Tue, 13 Mar 2007 20:03:01 GMT

Two Ultramax 225 floor standing high-efficiency, high-performance boilers from MHS have been installed at Ringwood Leisure Centre, Hampshire – the original location for the BBC’s toe-curling 1990s comedy The Brittas Empire.

The two boilers have been installed in conjunction with a CHP unit and provide heating and hot water for the leisure centre which includes two swimming pools, a gym and fitness studio, and a sports hall for badminton, trampolining and basketball.

The leisure centre, which is owned and managed by New Forest District Council, has a building management system to ensure the CHP unit is the primary source for heating and hot water, but uses the two Ultramax boilers to provide additional heat and hot water as necessary.

The Ultramax boilers replaced two old cast iron appliances and were installed on a mezzanine floor within the plant room, with much of the pipe work being completed offsite. This allowed the installation to take place without any downtime or closure of the leisure centre.

Barry Rickman, portfolio holder for leisure at New Forest District Council said: “The Council is delighted with the new boilers, recently installed at our Ringwood health and leisure centre. The new kit is effective, extremely efficient and, above all, economic to run. The combination of these three elements is good news for the council taxpayer.”

David Finch of Capita Symonds specified the boilers. He said: “We chose the Ultramax 225 boilers from MHS because they fitted perfectly with the boiler plant specification, work in a cascade format and are easily controlled by the building management system.”

Terry Wall from MHS Boilers provided on site technical support. He said: “It’s always good to provide a solution which not only exceeds the end users expectations, but delivers great fuel savings.”

The installation was completed by Dewco Ltd, Ringwood, Hampshire.

Heating system refurbishment: living separate lives

Tue, 19 Dec 2006 02:12:01 GMT

When it comes to refurbishing schools and colleges, municipal facilities or arts centres local authorities are faced with many choices.

With limited funds, tough decisions have to be made. The cost of replacing entire older heating systems can be prohibitive. Peter Gammon, Technical Product Manager for leading boiler supplier, MHS Boilers, believes there is a simple solution that is good for local authorities, good for installers and good for energy efficiency.

It’s an all too familiar scenario – the boiler plant is nearing the end of it’s life but the distribution system and heat emitters on the face of it will still appear to have some life span, but there are worries about dirt carryover from the (less than clean) existing system into new boiler plant and pumps etc.

So what do you do?

Well, there are a couple of choices – you can replace the whole system and boilers or you retrofit a new boiler onto an old system. Replacing the whole system is very often cost prohibitive and, if the rest of the building isn’t being refurbished, you can create all sorts of problems with closures due to structural work or removal and replacement of pipe work and heat emitters. The expense of replacing the whole system is not only due to the capital outlay of the new equipment and its installation, but the associated closure of the facilities – not always a problem if you have the school summer break to carry out the work, but not easy for a busy theatre or leisure centre.

Adding a new boiler onto an old system isn’t without risks as already mentioned. It’s not that the old system will breakdown and cause problems because you’ve added on a new high performance boiler – rather the opposite. You’re much more likely to cause damage to the new boiler because of the detritus and deposits from the old system.

There is a strong possibility that an older system will not have benefited from water treatment and therefore would have seen progressive corrosion. There is very often copious amounts of debris in an old system – most of which is likely to be ferric in nature. Without getting too technical, there is going to be a lot of magnetite (FE2O3) in low velocity parts of the system (the bottom of radiators for example), which will have accumulated very slowly over a number of years. As it has been accumulated slowly, it may not have caused any real problems. However, as soon as you drain down the system, you allow the silt and magnetite to dry out – which turns it into a fine dust that has the consistency of talcum powder. This isn’t too much of a problem in older boilers, which tend to have large, low velocity waterways, so the silt is spread thinly. However, with modern boilers you can have major problems.

The fine powder gets distributed when you refill or flush the system and is then free to flow into the new equipment such as pumps and valves, causing no end of headaches. The silt can also combine with the salts in the refill water and bake hard in the waterways of the new boiler plant. Also, being magnetic, the silt can clog around the armatures of canned rotor pumps and cause them to seize. So having invested in new high performance, high efficiency boiler plant, you might be causing all sorts of damage – blocked waterways, overheating of metal parts, nuisance operation of high limit thermostats and kettling noise to name but a few. Not only that, but coupling the old system to the new plant could cause damage to or failure of the boiler’s heat exchanger – the deposits act as an insulator, meaning the metal of the heat exchanger will retain the heat instead of passing it through to the water.

Is it really that bad? Does it really affect the efficiency of the boiler? Yes. It does and the reason is simple. The lining of debris that would be left on the heat exchanger of the new boiler can cause thermal drift in flue gas temperatures and reduce the efficiency of the boiler. It doesn’t need to be a thick layer either – a 1mm thick deposit can cause a thermal drift of 80-90oC that will in turn reduce the efficiency of the appliance’s output by more than 4%.

But that’s enough doom and gloom. How do you solve these issues? Thankfully there is a relatively simple way of fitting new high efficiency boiler plant to an old system – and it’s not rocket science either.

What you need to do is separate the old system from the new boiler plant and the best way of doing this is to use a plate type heat exchanger. This acts as a barrier between the old and the new and allows you to create a brand new mini-environment on the primary side of the heat exchanger onto which the new boiler is installed. By separating the new boiler plant from the old system you enable the water to be treated on boiler side, which will extend the life of the boiler, as well as enabling you to use a modern high efficiency sealed and pressurised boiler. The old system then can remain open vented and as dirty (and leaky maybe) as it was!

The separation allows the boiler to be easily pre-commission cleansed, without the associated problems of cleaning an old system. Power flush type cleaning can work well in a small, domestic context, but is much less successful in a commercial setting, where the volumes of chemicals required and the necessary flushing velocities to get them through the system make the desired results practically unachievable.

For specifiers, using a plate heat exchanger is not only best practice, but is now easy to achieve. For example, at MHS Boilers our new high performance Ultramax PB boiler has an option for an inbuilt plate type heat exchanger within the case – so not only are you able to install a new boiler onto an old system, you don’t even have to find additional space in the boiler room. It’s really that simple. As long as you have a temperature difference between the primary and secondary sides across the heat exchanger, it’ll work. If the temperature difference isn’t there, all you need to do is run the new boiler at a slightly higher temperature than the system or marginally reduce the operating temperature of the existing load circuits – or perhaps a bit of both!

This type of technology and system set up is already becoming popular across the industry and MHS has already provided many new boilers for use on old systems, separated by plate type heat exchangers.

The separation of the old system combined with a new high performance, high efficiency boiler, such as the Ultramax PB from MHS, is a real win-win situation. Not only is it sensible engineering, it also acts as a life insurance policy for your boiler plant – allowing it to operate with the peace of mind that it should last for the life span it was designed for. And with around 78% of the market being in replacement boilers, we think it makes great business sense too.

Huddling together to keep warm: district heating in rural areas

Mon, 18 Dec 2006 18:12:01 GMT

With wind blowing from the icy north and rain coming in at right angles, rural Britain isn’t most people’s idea of inspiration. However, Peter Gammon, MHS Boiler’s Technical Product Manager, thinks rural communities might just be able to lead the way in heating – and cut down on emissions too.

An isolated group of farm cottages, or a hamlet in “the middle of nowhere” is a lot of people’s idea of a rural idyll. Indeed, in a recent survey for the Countryside Agency, 61% of people living in the city and suburbs said they wanted to live in the country. But not everything in the garden is rosy. As Simon Hart from the Countryside Alliance says: “Our countryside is under threat as never before - not just from the decline of farming and of related employment but from the accelerating disappearance of village services and amenities, the lack of adequate public transport, the increasing scarcity of affordable housing for rural people themselves and the steep rise in social exclusion threatening the cohesion of many local communities.”

But what’s that got to do with boilers, domestic heating and manufacturers? According to a recent report by the government’s Commission for Rural Communities ten affordable new homes need to be built in every English village to solve the rural housing crisis. And one of the Campaign for Rural England’s central tenets for new housing in the countryside states houses should be: “built to high environmental and design standards, so that new rural homes – be they private sector or affordable – enhance rural communities and contribute to protecting the environment as well as keeping down running costs.”

It follows then that, if you look at the bigger picture you’ll find that the countryside is not only facing many major challenges, it is also the testing ground for new types of technology – both heating and energy. Whether it’s proposed wind farms on the edge of Dartmoor, wave power off the coast of Scotland, or biomass boilers in Carmarthenshire, rural areas can be a hot bed of innovation and technological change. Here at MHS Boilers, we are continuing to embrace this love of innovation and have developed a networked or district heating system that is perfect for country life. What’s more it can be used with many different types of boilers – gas or oil fired, biomass or CHP. That way everyone can even benefit from greener technology and be protected from fuel shortage.

So what is it and how does it work? It’s basically taking a concept, which was used as far back as the Roman Empire, and bringing it bang up to date. A central heat source – boiler or CHP unit – is networked to a group of buildings, homes or whole district. The Nexus substation from MHS Boilers, for example, draws heat from a central boiler plant or CHP system via a simple LTHW loop. It then delivers all the functions of a combi boiler –providing heating controlled by the occupants via a programmable room thermostat and instantaneous hot water (up to 19 litres per minute). This degree of control is in stark contrast to old style systems. Additionally the Nexus also features a Siemens Building Technologies heat meter, which not only ensures accuracy when calculating bills but can also be monitored remotely via an M-Bus System.

Unlike installing separate boilers in every dwelling within a small rural community, district heating eliminates the need to supply gas to every home – especially in particularly remote areas where there is no mains gas. Networked heating also does away with the problem of fluing (especially the unsightly pluming effect of high efficiency condensing boilers) and eradicates the increasing problem associated with condensate waste from individual condensing appliances.

But it’s not just for rural housing trusts or isolated communities. The Rural Housing Commission recommended that disused farm buildings might be reclassified as brownfield site and therefore relaxing the guidelines on what can be built. Networked heating could also work very well in this instance where agriculture has declined as a main source of income and farm buildings are used for purposes other than storing tractors, combine harvesters or cattle. Many of these farms are diversifying, turning unused and sometimes dilapidated buildings into light industrial units, holiday lets or affordable housing.

Networked heating is a perfect solution, giving the landowner the opportunity to develop the land and use this heating technology to their advantage – offering control over metering – even down to monitoring energy usage of each holiday cottage and charging the guests accordingly!

An almost hidden benefit of networked heating, and in particular the Nexus system, is its long, trouble free life, thanks to the extensive use of tried and trusted combi components. Also, the absence of gas in the units means that people without Gas Competency certification can carry out maintenance and inspections periodically. The units are also very easy to site – they’re small and the absence of gas means no flue so they can be installed virtually anywhere within a building. Naturally, they can be used with either radiators or underfloor heating and can be weather compensated if required – the outside air temperature sensor is included as standard with the Nexus unit.

So what of the future? As energy efficiency in the domestic environment becomes even more important, pressure to provide affordable housing in rural areas grows, and renewable heat sources such as biomass become standard, networked heating will inevitably become a popular choice in the countryside. We at MHS Boilers are looking forward to being at the forefront of change – for the better.

New Ultramax PB: smaller, cleaner, greener, quieter

Wed, 04 Oct 2006 14:10:24 BST

Leading boiler supplier MHS Boilers has launched a new power-packed range of stainless steel, fully condensing floor-standing boilers. The new Ultramax PB from MHS Boilers also solves the problem of fitting a brand new, energy efficient, high performance condensing boiler to an old system, thanks to its use of simple separator technology. A plate type heat exchanger option kit can easily be incorporated into the Ultramax PB boiler case to act as a barrier, protecting the boiler from the effects of dirt accumulation in older systems. Alternatively, for new installations a low loss header option kit can be accommodated within the boiler’s smart casing.

Available in four models (65kW, 85kW, 100kW and 120kw) the Ultramax PB has a small footprint, taking up less than 0.51m2, making it a perfect choice where boiler room space is at a premium. However, its compact size belies its power and efficiency. Its pre-mix modulating burner gives a return efficiency of up to 109.8% and a modulation range up to 6:8:1. What’s more its NOx emission does not exceed 33 mg/kWh – easily meeting the stringent requirements for the highest BREEAM points score for low NOx pollution. The Ultramax PB is also very quiet with noise levels not exceeding 48 dBA.

A comprehensive programmable boiler/system controller is included as standard, which allows connection to intelligent room controls if required, and the Ultramax PB’s flue connection is suitable for either room sealed or open type systems with the capability for extensive lengths of flue to be accommodated.

The Ultramax PB also has an on-board direct weather compensator which provides both comfort and energy efficiency for the end user. For peace of mind, the primary heat exchanger carries a five-year guarantee.

Peter Gammon, Technical Product Manager, MHS Boilers, says: “The problem of retrofitting a new high performance boiler to an old system can be fraught with difficulty, but the new Ultramax PB has made it simple for installers. With its optional plate type heat exchanger, you can now attach it to an older system without problem. The great news for customers and end-users is that they can enjoy the performance and environmental benefits of condensing boiler technology, without having the aggravation and expense of an entirely new heating system.”

MODULAR BOILER INSTALLATION IN A BOX

Fri, 26 May 2006 16:05:24 BST

MODULAR BOILER INSTALLATION IN A BOX:
POWER, SIMPLICITY AND INNOVATION FROM MHS STREAMLINE

MHS Boilers Limited, innovators in modular boiler technology, has further advanced the modular concept with the launch of the Streamline FS 150 and 225 – a simple to install system with the capacity to link units to provide up to a staggering 900kW of highly controllable output, making it ideal for new and retrofit applications in such sectors as health and education.

Whilst many manufacturers are now offering a pre-fabricated rig system for multiple boiler installations (a system pioneered by MHS in the 90’s) the Basildon based company has moved this technology on with the introduction of the Streamline. The FS 150 utilises two vertically mounted fully modulating condensing burner/heat exchanger units, while its bigger brother operates with three units to give it a maximum output of 225kW with 15 to 1 turndown and efficiency up to 109.5% net.

Additionally the Streamline’s feature a single flue system, system connection via an integrated low loss header and are operated by a common control system within a compact, single casing. The smaller of the two models can be easily upgraded to 225 kW by retrofitting a further 75kW module. The Streamline FS may also be room sealed if required.

With many of the necessary installation tasks already completed and fully tested off site, installing the Streamline is a speedy and simple process. The units come with heavy duty castors and a unique, wheeled, lifting handle which allows a single engineer to site the Streamline with a minimum of physical exertion and in line with health and safety guidelines on manual handling.

Ian Bradley, Managing Director, MHS Boilers said: “ Innovation is at the heart of everything we do at MHS and the Streamline is yet another product which delivers benefits for our customers – power, flexibility, ease of installation and simplicity. The Streamline gives installers the ability to install a modular boiler system with no extra hassle – it’s really just as easy as installing a single boiler.”

Details of these products and the full range of boilers and hot water generation equipment are available from www.mhsboilers.com
