"heat recovery systems"

Our AEROMAT window ventilator range and AEROTUBE single-room heat recovery systems qualify for the UK government’s new Green Homes Grant.

Salthaven Apartments, Tower Road, Poole, DorsetThe Salthaven apartments in Dorset aimed to deliver luxury living for occupants. Bayview Developments not only constructed beautiful homes for them, but also opted for highly energy efficient heating within the new development.Each of the 12 two or three bed apartments have been fitted with their own individual exhaust air heat pump (EAHP). This technology has been installed in buildings across continental Europe for many years but is now being used more commonly within the UK. Bayview Developments were looking to exceed their planning requirements by reducing carbon emissions and providing cost savings for occupants. NIBE’s innovative EAHPs were therefore the ideal solution.The solution to the projectA NIBE F730 EAHP system removed the need for gas boilers, something Bayview were keen to do given the UK’s net zero targets and commitment to phase out the technology. As heat pump technology is powered by electricity, no gas has been installed at the site.The NIBE F730 unit can be found in the utility room cupboard of each apartment and is comprised of a ventilation system, a hot water cylinder and a heat pump – a complete ‘all-in-one’ product. It works by drawing warm air from the kitchen and bathroom to feed the heat pump, which extracts the heat energy. The recovered energy from the ventilation system is used to drive the heat pump process, which heats the underfloor heating and provides water for the integrated 180litre hot water cylinder. The stale air from the ventilation system is then released outside, whilst fresh air from outdoors is introduced via wall inlets with cleanable filters. The efficient system minimises energy consumption by combing ventilation heat recovery with heat pump technology, that is perfect for well insulated new build properties such as these.The ResultsThe EAHP systems meet the average annual heat demand of 6019 kWh for each individual flat whilst also providing instant hot water. Occupants are able to schedule their heating to suit their timetable and energy tariffs, and therefore benefit from lower energy bills. The system performance factor (SPF) measures 3.33 – this means the system is very efficient as every kW of electricity used to run the unit produces approximately 3 kW of heat energy.NIBE utilised connected electricity meters in 3 apartments to remotely monitor the systems performance across a 12-month period. NIBE was thus able to see how the systems met energy demand consistently for residents, keeping them comfortable and warm throughout the year.Energy consumption data shown in Figure 1 visualises electricity consumption data from the monitored apartments throughout the year. This data also covers the provision of all heat pump controls and continuous mechanical ventilation.Figure 1: 2022 Energy Consumption data for monitored apartments.The all-in-one system has shown a noticeable reduction in energy bills for each apartment too, with all 3 monitored apartments experiencing both monthly and cumulative cost reductions in their energy bills as shown in Figures 2 and 3. This comes with the additional peace of mind that consumers will be kept cool in the summer months with ventilation with no increase in costs.Figure 2 and 3: Monthly and Cumulative Heating Bills for Apartment 11 with the NIBE F730 heat pump compared to a natural gas boiler.The occupants of Apartment 11 are saving on average £130 on their annual heating bills with the heat pump system in comparison to a natural gas boiler, even with the additional provision of mechanical ventilation. We expect that these savings will continue to increase as the Government seeks to rebalance green levies to decrease electricity prices.Sunstone Energy Ltd, the installer for this project, told us how easy the control system is to use for this heat pump, allowing for heating and hot water to be available at any time during the day. The building also benefits from insulation, underfloor heating, smart controls, double glazing, hot water cylinders and mechanical ventilation with heat recovery (MVHR).TestimonialVictoria and John are both residents of the Tower Road apartment complex and have been comfortably living with the exhaust air source heat pump system for a year. They added “We are delighted so far with the new heating system, and love that it has been providing us with heating and hot water throughout the year, keeping us warm in the cold winter months. The heat pump works just as well as our older systems and it is great to know that we’re also doing our bit for the environment in the process.”About the installerSunstone Energy Ltd takes responsibility for delivering complete renewable solutions appropriate to their client’s properties.

An architect designed, self-build house with annexe for a multi-generational family built to zero-carbon standards.The scheme’s design is influenced by the architectural vernacular of the area. The surrounding houses are a legacy of the Land Settlement Association scheme, with distinctive mansard roofs, steeply sloping gables and dormer windows, constructed in a simple red brick with terracotta plain tiles.The mansard is reflected in the new house with the roof extending down to form the walls. Instead of terracotta tiles, large format slate has been used to form a modern equivalent. The house is mainly slate tile; however, it was felt important to also reflect local brickwork. As such, brickwork was used for two huge brick-faced chimney stacks that rise through the gable.PROJECT INFOTo form a contrast with the very smooth grey of the slate, a textured red brick with slight colour variation was sought. White mortar lightens the brickwork while recessed mortar joints are used inside to provide shadow to each brick. Perforated brickwork surrounds the stone coping on both chimney stacks, adding visual interest to the building through both the materials and the shadows created by the brickwork perforations.The brick selected was stock thrown Hampton Rural Blend from Forterra’s Ecostock range. It has a rustic finish resembling handmade brick. Ecostock bricks are manufactured using the latest technology in sustainability and production efficiency, producing bricks with low embodied energy as well as advanced colour consistency, dimensional accuracy and quality.The structure incorporated huge amounts of insulation, a mechanical ventilation with heat recovery system, and a solar photovoltaic array at the bottom of the garden, along with a ground-source heat pump. These installations will ensure that the house generates more electricity than it could ever use.

Royal Winchester HouseComer Homes is renowned for the high quality of its residential and commercial developments, which span London, Hertfordshire, Dorset and throughout the South East. Its latest project is Royal Winchester House, a landmark building of one and two bedroom apartments at the heart of Bracknell's new town centre. As a planning requirement of Bracknell Forest Council, Comer Homes was required to provide a sustainable, low energy form of heating that would offer a reduced carbon footprint, as well as being affordable to run.The SolutionComer Homes specified F730 Exhaust Air Heat Pump systems from NIBE for all 337 apartments on the development to ensure they could meet their renewable targets. The new homes builder employed MKP Consultants Limited to undertake the building services design as they had previous experience of NIBE systems on other apartment developments in the area.The NIBE F730 Exhaust Air Heat Pump system was an ideal solution, as it offers mechanical extract ventilation, alongside heating and hot water in a compact design. The heat pump units were installed in a service cupboard in each apartment, as they have a small footprint of only 0.6m2.NIBE F730 operates by recovering energy from the ventilation air and, if desired, extracted from outdoor air, the heat energy is absorbed by the heat pump using a vapour compression process and subsequently transferred to the water-borne heating system, in this case an underfloor heating system. The integrated 180L domestic hot water cylinder also ensures a plentiful supply for the one- and two-bedroom properties.A sustainable solution, NIBE F730 keeps energy consumption to a minimum. The efficient control system automatically adjusts the indoor climate for maximum comfort for the occupant, using a combination of weather compensated control and the low energy inverter driven compressor.Each apartment is also fitted with a NIBE RMU 40 room controller, to allow greater flexibility of control for users and if required can be easily connected to NIBE’s internet remotely monitoring and control platform UPLINK™.Thanks to this innovative heat pump system, residents at Royal Winchester House are set to benefit from lower energy bills and a reduced carbon footprint.The ResultsThe NIBE F730 system complies with Parts L, F and G of the building regulations, and helps to meet planning requirements designed to reduce energy consumption and carbon footprints within residential housing developments. External noise is kept to a minimum and building aesthetics are unaffected by the need for external plant.TestimonialHead of Projects at Comer Homes, Jack O’Brien explains: “We were looking for a heating and ventilation system that would be both sustainable and affordable to run. We have been impressed with the performance of NIBE’s heat pumps, with their high efficiency, low noise and low running costs further enhancing the sustainability of the whole development.”About Royal Winchester HouseRoyal Winchester House is a landmark building of high specification 1 and 2 bedroom apartments available to rent. The unique design and architecture of Royal Winchester House creates a striking and impressive presence from the ground floor retail spaces up to the luxury penthouse levels.Royal Winchester House has been built for the private rental market and the development is being managed by Chancellors estate agency. The apartments benefit from high standards of insulation and air tightness. In addition to the NIBE heat pumps, the whole development has been fitted with a biodigester for the repurposing of food waste, as part of reducing waste sent to landfill and to add to its sustainability.

South Lanarkshire College (SLC) in Scotland has opened a new, ‘zero-energy’ teaching block on its East Kilbride campus. Specifically designed with first-rate environmental credentials in mind, it boasts a whole host of efficiency-enhancing measures – including highly insulated floors, walls and roofs, triple-glazed windows, low-energy lighting and electrics, rainwater harvesting and solar PV panels on the roof. The college approached NIBE Pro Installer Anderson Floor Warming and Renewables in search of a system that would meet the heating requirements of the eight-classroom block in the most sustainable, cost-effective and reliable way possible.The SolutionSLC already has a range of NIBE products in its on-site renewables training centre, which students use for practical sessions, so a heat pump from NIBE was the natural choice to heat the new block. Mike Anderson, director at Anderson Floor Warming and Renewables, specified, designed and fitted a NIBE F1345 40kW ground source heat pump (GSHP) system to complement the building’s water-based underfloor heating, which operates at similarly low flow temperatures.ResultsNow up and running, the NIBE system is so efficient that it has been awarded a rating of A+++ in line with energy labelling criteria under the ErP Directive. SLC’s new teaching block has become the first building in the UK to achieve a BREEAM sustainability rating of ‘Outstanding’, with the facility excelling in all 10 assessment categories – from energy, waste and water to health and wellbeing.Customer Testimonials“We pride ourselves on our forward-thinking approach to sustainability at SLC, and we couldn’t be happier that our new teaching block has been deemed ‘Outstanding’ by BREEAM assessors. The NIBE heat pump system and the solar PV panels combined generate enough renewable energy to meet the block’s entire heating and power needs, making it a ‘zero-energy’ building. It really is a huge asset to the whole college – not only from a resource point of view, but also as a real-life example of sustainability in action. As well as being a valuable learning space for our construction and energy students, it’s a place for us to bring local businesses and community groups, and showcase the benefits of low-carbon, low-resource buildings first-hand.”Stewart McKillop, principal at South Lanarkshire College

Hexham and Northern Mart is an auction house in Hexham (25 miles west of Newcastle), specialising in the sale of livestock and cattle to farmers across the North East of England. The business decided it was time to replace its old gas-fired heating system with a more sustainable alternative – one that would not only reduce energy consumption and running costs, but also earn additional income through the Renewable Heat Incentive (RHI). Minimising impact on day-to-day operations during the transition was another key consideration. Managing director Robert Addison tasked renewable energy specialist and NIBE Pro Installer Calibrate Energy Engineering with finding the right solution to meet the heating and hot water demands of the 112,050sq ft building.The SolutionThe team at Calibrate specified, designed and installed a 300 kW renewable heating system made up of five 60 kW NIBE F1345 ground source heat pump (GSHP) units. They paired this with a 50 kW solar PV array, fitted to the roof of the main pen area, which partially powers the NIBE GSHP system. The in-ground heat collectors required for the GSHP were laid in the fields around the buildings, with the controls units sited in a prefabricated plant room to the rear of the premises. The installation took just three months from start to finish, and during this time it was business as usual for Hexham and Northern Marts.ResultsDocked together in a cascade for greater output capacity, the five NIBE F1345 GSHP units now meet 95% of Hexham and Northern Marts’ 394,000 kW/h annual heating and hot water demand. Meanwhile, the 50 kW solar PV array generates enough free electricity to offset a significant 50% of the power needed to run the GSHP system. Hexham & Northern Marts is set to make a 236% return on investment – reaping an estimated £862,000 in energy savings and commercial RHI payments over the next two decades.Customer Testimonial“We couldn’t be happier with our new renewable heat and power sources. As well as delivering instant reductions in energy usage and subsequent savings on heating bills, the NIBE GSHP solution is providing us with a steady stream of income for the next two decades, thanks to the RHI. The power produced by the solar PV panels is an added bonus, and makes running the heat pump system even more cost-effective.“As a result, we’re expecting to see returns of more than double our original investment over the next 20 years – which is absolutely invaluable from a business point of view. Not only this, but we’ve got an efficient, reliable renewables setup that’s fit for the future, and will continue to deliver ongoing savings for years to come.”Robert Addison, managing director, Hexham & Northern Marts

Teesside-based logistics firm AV Dawson has built a new 130,000m3 warehouse specifically to store £15m-worth steel coils for a nearby international car manufacturer. With the steel at risk of ‘sweating’ and rusting in high humidity levels exceeding 65%, the company was tasked with ensuring a very specific climate for the warehouse (without which the steel would be rendered unusable), while also maintaining low energy costs.The SolutionHoward Tribick, director at local renewable energy specialist and NIBE Pro Installer HT Energy, specified, designed and fitted ten NIBE F1345 ground source heat pumps (GSHPs). Given the site is built on top of an active water table (the River Tees), Howard and the team were able to make the most of the surroundings as a natural energy source. The heat pumps collect heat from 70 bore holes, each 150m deep – a total of 10,500m of active bore hole depth. Each 60kW GSHP is paired with its own ventilating unit and 500L NIBE UKV buffer tank – producing a total output of 600kW. Solar panels on the roof provide an additional 220kW to help meet the warehouse’s electricity needs.ResultsWith the ten GSHPs now fully operational, the results have been even better than expected – with a seasonal performance factor (SPF) of 3.65 and average humidity levels of just 47%. Interconnected with 3km of header pipes, the GSHPs are spaced equidistantly along one side of the 264m-long building. The units are set up as separate systems, so they can work independently of each other or together as required. This provides an added level of security for the customer, ensuring the system can cope at all times and the steel is kept at optimum conditions.Customer Testimonial“This system made perfect commercial sense for us. While the initial outlay was greater than some of the other alternatives, GSHPs provided the most cost-effective solution by far in the long term. In fact, compared to natural gas, we will be making an impressive energy saving of 1.58 million kW/h each year. Our projected payback period is just ten years and we’re also benefiting from Renewable Heat Incentive (RHI) payments for each unit of renewable energy we’re generating.”Gary Dawson, managing director, AV Dawson

Background to the projectSouthway Housing Trust is a South Manchester based housing association managing 6,000 local homes.Southway has pledged to be zero-carbon by 2038 and has identified switching its homes from gas to electric heating as crucial to achieving this target.In 2022, a survey of Southway’s residents found that 88% were keen to reduce their impact on climate change, and Southway’s commitment to reducing carbon is in line with Manchester City Council’s net-zero ambitions.The Arrowfield Low Carbon Living Project represents an early and ambitious retrofit of a south Manchester neighbourhood that will reduce the estate’s carbon footprint by as much as 50%.Southway is replacing 396 of Arrowfield’s inefficient gas boilers in-line with long term government plans to electrify heat and will also improve the fabric of homes to make them more energy efficient.The scale of the project, part funded by the European Regional Development Fund (ERDF), has made it one of the UK’s biggest home retrofit schemes.NIBE products used:NIBE F2040 Air Source Heat PumpKey stats:112 NIBE F2040 Air Source Heat Pumps installedContributes to project to remove 370 tonnes per annum of CO2 in ArrowfieldInstalled by Rothwell Plumbing GroupPart of a project to retrofit 199 homes with air source heat pumpsThe solution to the projectArrowfield Low Carbon Living is a flagship scheme in Manchester, retrofitting 199 homes and 197 apartments with air source heat pumps. NIBE was chosen as one of two heat pump providers to bring low carbon, sustainable heating to residents living in the Arrowfield estate. NIBE’s high quality, reliable heat pump systems provide optimum savings and automatically adapt to each home’s output requirements.Rothwell Plumbing Group (RPS) was chosen as the installation partner for the project, with a proven track record for delivering high quality heat pump systems, in both the public and private sectors. RPS are also MCS & Trustmark accredited, with the experience and technical ability to install NIBE systems to the highest of standards.Southway’s aim is for the project to act as a learning process and blueprint for how it can scale up the retrofitting of its entire housing stock over the next 15 years.Ahead of this ambitious project, a community engagement programme enabled greater awareness of heat pumps as a low carbon heating solution, whilst providing the opportunity to listen and respond to resident feedback.The Arrowfield Hub, located in in a repurposed empty house on the estate, became a venue for regular engagement between the residents and the project team, creating an open forum for questions and comments on the proposed scheme.The Hub was also heated by an air source heat pump, allowing residents to witness a live heat pump in operation and experience the warmth of the building.Residents were also able to express their concerns surrounding the project, and these could be addressed accordingly. This regular and open engagement was key to keeping residents informed and more familiar with their soon-to-be new heating systems.The Hub also allowed for the project team to dispel common myths and misconceptions about air source heat pumps and reassure residents that their homes would remain warm throughout the yearThe Results112 NIBE’s F2040 Air Source Heat Pumps have been providing heat and hot water to residents across the estate, adapting to the requirements of each and every home in the estate, whilst providing powerful output even down to outdoor temperatures as low as -20°C.The systems will provide homes across the estate with optimised energy and cost savings, whilst supplying a supply line temperature of up to 58°C regardless of outdoor temperatures.TestimonialMatt Roberts, Strategic Director of Property and Development at Southway Housing, said:"Community engagement for the Arrowfield Low Carbon Living Project was central to the project's aims. Foregrounding the needs of Arrowfield's residents as central to the project’s implementation, helped us to better convey the benefits of low carbon heating and address concerns and suggestions brought forward by homes set to benefit from the retrofit scheme.Air source heat pumps are essential to Southway Housing Trust decarbonising our housing stock and achieving our net-zero goals. Working in partnership with NIBE is part of that process and has contributed to achieving carbon savings of 370 tonnes CO2 per annum on Arrowfield.”About the installerRothwell Plumbing Services Group Ltd, formed in 1997, are a family run business specialising in delivering renewable solutions across the North of England.

OverviewA successful installation of 40 x Powrmatic SRP U Tubes at a hangar facility in Boscombe. With the system design by Powrmatic, ABS, a leading HVAC and installation company, was entrusted with this significant installation project. The installation aimed to provide efficient heating performance, reduce energy costs, and improve the overall comfort and functionality of the hangar.Project BackgroundThe Weighbridge Hangar Building 499 at MOD Boscombe Down operated by QinetiQ required a new heating system due to the life-expired existing system. The hangar required a powerful heating system that would operate efficiently during the cold winter months while reducing energy costs. A new Powrmatic SRP U-tube herringbone radiant heating system was produced in line with the design intent of WYG on their tender documents. J & B Hopkins secured the M & E contract and employed the services of ABS Ltd to undertake the installation of the radiant heating system. ABS Ltd, formed in 1978, offers a full range of professional services including the installation and maintenance of both radiant and warm air heating systems to both commercial and industrial properties throughout the UK.SolutionThe MOD hangar facility, situated on an exposed location, at Boscombe Down required a robust heating solution to withstand the cold winter months. 40 Powrmatic SRP radiant U Tube PVU50 Hi/Low heaters each rated at 50kW on a herringbone system layout with ducted fresh air onto each burner to comply with fire safety standards were installed by ABS Ltd. To maximize efficiency, the heaters mounted at an impressive height of 23 meters in line with Powrmatic’s design drawings were arranged in 8 lines of 5, with 3 heaters connected to one fan and 2 heaters connected to another fan. The heating system incorporated Powrmatic MC200 controllers and black bulb sensors for precise temperature control across the hangar.ResultThe final stage of the installation was completed by J & B Hopkins, arranging for the necessary gas and electrical distribution services to the radiant heaters and discharge fans. The 40 Powrmatic SRP radiant U Tubes installed by ABS Ltd effectively heated the facility, providing a comfortable and conducive environment for the workforce during the winter season. Additionally, the new heating system reduced energy costs and eliminated the need for multiple exhausts on the rooftop hence retaining the aesthetic design principles of the hangar. The commissioning was successfully carried out when all services were completed, providing a satisfied client with a capable heating installation within the hangar, for the exposed site location.

Overview A collaborative project with our long-lasting customers Jet Environmental Systems resulted in the successful installation of three HEM-SLx 525kW heat exchange modules, aimed at providing warehouse heating for a prominent automotive component warehouse in Ellesmere Port. The project involved a bespoke-designed air handling unit (AHU) expertly manufactured by Linton Services Ltd and delivered as a comprehensive turnkey heating solutionBackgroundThe warehouse had a substantial floor area of 39,000m2 and a volume of 760,000m3. The main requirement was to maintain an internal temperature of 16C degrees, even during outdoor temperatures as low as -4C degrees. To ensure efficient heating and uniform distribution throughout the space, a HEM-SL heating solution with a capacity of 525kW and an airflow of 37.5m3/s was needed. The client preferred natural gas as the heating fuel, which Jet Environmental incorporated into their custom-designed air handling unit (AHU) manufactured by Linton Services Ltd in Presteigne.SolutionThe warehouse layout and heating load necessitated the use of three air-handling units. To ensure a reliable and robust heating system, Jet Environmental selected Powrmatic as the heating supplier. Jet Environmental, Linton Services, and Powrmatic have a longstanding relationship and extensive knowledge of each other’s businesses. This familiarity ensures seamless integration of their products and expertise.Each custom-designed HEM unit was manufactured in the UK at Powrmatic’s manufacturing in Ilminster, Somerset.

The customized AHUs, designed by Jet Environmental and manufactured by Linton Services, effectively delivered the required heating capacity to maintain a consistent internal temperature of 16C degrees. Powrmatic’s reliable heating equipment ensured optimal performance and met the client’s expectations.The client was impressed with the comprehensive turnkey solution provided by Jet Environmental Systems. They were particularly satisfied with the partnership between Jet Environmental, Linton Services, and Powrmatic, which demonstrated a deep understanding of their businesses and the ability to deliver a reliable and efficient heating system.Overall, the successful completion of this project showcases the expertise that Powrmatic has in providing effective warehouse heating solutions for industrial applications.

Zoo Animal Enclosure Heating SolutionIn partnership with HEVAC Services Ltd of Kings Langley, Powrmatic was approached to develop a heating solution for the White Rhino’s House at Whipsnade Zoo, which saw the installation of an overhead gas-fired (LPG) continuous radiant heating system, as the previous electric heating system inside their indoor habitat was not efficient enough and heat was escaping through the timber structureProject BackgroundThe White Rhino house at Whipsnade Zoo is the home to a herd (also known as a “crash”) of seven southern white rhinos, Sizzle being the only male – the six females are; Mikumi, Bertha, Tuli, Jaseera, Fahari, and Nandi. Sizzle and Tuli are the parents of the latest baby rhino Nandi born in August 2021.The heating inside their indoor habitat at Whipsnade was not efficient enough. Localised electric heaters were spread around the large space to create coverage, but the heat was escaping through the timber structure. It was decided to upgrade the structure by foam insulation to the internals of the asbestos roof and to provide a new continuous gas-fired overhead radiant heating system providing blanket heat coverage to the complete floor area of the house.  Project SolutionHEVAC Services Ltd of Kings Langley, Hertfordshire, who undertake servicing of HVAC equipment at Whipsnade Zoo on behalf of Pareto FM for the end client ZSL (Zoological Society of London), approached Powrmatic to develop a heating solution for the rhino’s house. The brief was to provide an overhead gas-fired (LPG) radiant heating system to blanket cover the complete floor area of the rhino house, but also design it so that it could be zone controlled, should one of the herd have a need to be in an area of a higher or lower temperature.The LPG propane tanks for the heating system needed to be sunk into the earth at the edge of the rhino house to avoid having to remove any trees, thus maintaining the conservation ethos of ZSL. For a structure such as the rhino house, being the size of a large sports hall, a Powrmatic SRP-PCV+ continuous gas-fired radiant tube system comprising; 4 x 73kW burners was the proposed solution, arranged in 4 temperature zones, with the new MC400/C controller and just the one flue discharge to atmosphere.Project ResultThe installation of the new PCV+ continuous overhead radiant heating system was skilfully undertaken by HEVAC Services Ltd, with the contract programme being driven by the daily habits of the rhino herd! Whether they wanted to be in their house or out on the field. Thus, the logistics of undertaking the heating installation were unique compared to working in a standard commercial/industrial environment.The White Rhinos now have a refurbished home and a heating system that delivers radiant heat in exactly the same way that we (and the rhinos) receive energy in the form of heat from the sun. Radiant heating systems efficiently radiate infrared radiation, which is the transfer of energy in waveform from a hot surface to a relatively cooler surface without heating the medium between. Thus, the rhinos can bask under the radiant heat, whether indoors or outside under the sun.The ZSL Whipsnade Zoo White Rhino Enclosure now benefits from a highly energy-efficient Powrmatic SRP-PCV+ system, listed on the Carbon Trust Energy Technology List (ETL), endorsing the Seasonal Space Heating Energy Efficiency of; 92.1%, and thus delivering low; energy usage, fuel bills and carbon emissions minimising their impact on the environment.

Hatfield Place, a luxury country house wedding venue, chose Junckers solid wood flooring fitted with Leveldek underfloor heating system for its newly developed building. The new foyer, ceremony hall and wedding breakfast room overlook the original walled garden, with views of the beautiful parkland to the rear. The redeveloped building is bright and airy with large feature windows and high ceilings. In the foyer, a spacious room with seating for up to 300 guests, Junckers 22mm Oak Variation flooring provides a warm and lively backdrop, adding character with its subtle colour variations and natural grain patterns. In contrast, the ceremony hall and wedding breakfast room were fitted with Junckers’ Oak Harmony plank flooring, a wide board floorboard which gives a more uniform impression required for the formal spaces. Both floor types were pre-finished in Junckers’ popular Ultramatt lacquer, a strong and durable finish with no surface sheen. Delivered pre-finished, the floors are ready to walk on as soon as they have been installed and will withstand years of dancing and dining with the correct maintenance. The floors in all three rooms were installed over Leveldek, Junckers’ fully integrated underfloor heating and levelling system. Working in partnership with Jupiter Heating Systems, the Leveldek system was developed to simplify the specification process to offer a versatile levelling system, underfloor heating and solid hardwood floor from a single point of supply. Underfloor heating is the most efficient way of heating a large, open area. Specifying Leveldek offered Hatfield Place an all-in-one solution whereas traditionally, installation of the heating system, levelling system and the floor itself would have to be separately sourced. The system is efficient and cost effective to run, ideal for use in a large space. For energy efficiency and fast acting warm-up time, the heating pipes are installed directly beneath the floorboards and the panels are insulated and reinforced for outstanding heat output. The system can be used on an uneven substrate as varying heights can be achieved with the stacking cradles. For more than 30 years, Junckers’ wooden floors have been recognised as the only type of solid hardwood flooring on the market stable enough to be guaranteed for use over underfloor heating. Junckers offers a full guarantee for the system, which is recommended for residential and commercial buildings as well as sports and dance. The flooring contractor was PICA Floorings. 

Project BackgroundThe Harrow Club in London W10 has been creating positive futures for marginalised young people in West London since it was formed in 1883 as The Harrow Mission Church. Through general youth clubs and specialist interventions, they aim to empower young people to complete their education, avoid anti-social behaviour and become positive contributors to society. They work with up to 500 young people each week across 6 clubs, helping them to recognise their full potential.The Harrow Club with high ceilings, period windows, and exposed beams has a large sports hall which is a preserved reminder of the Club’s heritage, plus a smaller dance studio, both of which were heated by an old continuous gas-fired radiant tube system that had ‘life-expired’.Project SolutionBuilding Services Engineering Consultants, SS and A of Great Portland Street were commissioned by the Harrow Club to explore options for the replacement of the old radiant heating system. They called on the expertise of Powrmatic to review possibilities and offer a solution.The installation of the new systems was expertly undertaken by Industrial Commercial Environments Ltd of East Sussex. Radiant heating is the most suitable form of heat for both sports halls and dance studios as the lower air temperature for the same comfort level is approx. 5ºC lower than with a warm air system, thus producing a beneficial environment for the activities. A new Powrmatic SRP-PCV+ continuous gas-fired radiant tube system was the proposed solution. This enabled the installation to follow the route of the existing thus minimising costs and disruption during the works.Project ResultThe new Powrmatic SRP-PCV+ continuous radiant heating systems in the two halls have provided the Harrow Club with energy-efficient heating for the next two to three decades. These systems deliver the comfortable environment crucial for the well-being of the young people that the club nurtures in their quest to improve their futures.The Harrow Club now benefits from the energy-efficient Powrmatic SRP-PCV+ systems, listed on the Carbon Trust Energy Technology List (ETL), reducing their fuel bills, carbon emissions and thus their impact on the environment.
