"underfloor heating systems"

A Uflex underfloor heating system consisting of fifteen zones has been installed as part of a barn conversion project in Thirsk, North Yorkshire. Here, we talk to Oliver Carter Plumbing and Heating, the G1 installer who completed the installation, to discover how they found working with the new Uflex underfloor heating range from Grant.

Heat Mat's electric underfloor heating mat system has been installed at the Kench, Hayling Island, recently shortlisted for the 2014 RIBA Manser Medal architecture award. The property won a RIBA South regional architecture award in 2013. The holiday home has been designed in the spirit of the original chalets once located in this area, with an open-plan living space and floor to ceiling glazing. Space is limited in the property, therefore underfloor heating was proposed as the ideal solution. Heat Mat's 160W underfloor heating mats and NGT thermostat were installed.

A Grant Uflex MINI low profile underfloor heating system has been installed throughout the entire downstairs of a four-year-old property, providing the homeowners with complete comfort in the rooms they occupy the most frequently.

The revolutionary, award-winning underfloor heating system Schlüter-BEKOTEC-THERM was the natural choice for one of the UK’s greenest self-build projects.

An Essex-based project centring on the provision of a much-needed National Autistic Society (NAS) school has seen the installation of electric underfloor heating system Schlüter-DITRA-HEAT-E-DUO into the 60 houses built to off-set its costs.

Guests to a new luxury spa at one of London’s most famous hotels are relaxing in comfort after the installation of the environmentally friendly underfloor heating system, Schlüter®-BEKOTEC-THERM, by Schlüter-Systems.

This new-build house was in a remote location and off-grid for mains gas, the house was to be heated by a heat pump and so efficiency was a major consideration for the project. The Lewis Deck system was chosen for the 1st floor of the building to provide the same efficiencies for the underfloor heating as the concrete ground floor as well as providing a high level of acoustic separation for this quality timber frame project. The build-up included the Lewis flanking and resilient strips, Lewis Deck, Anhydrite liquid screed and underfloor heating pipes.

Hastings Pier was devastated by fire in 2010. As part of the £14.2m restoration, the condemned Pavilion Restaurant was renovated and heated by Heat Mat. The restaurant was housed within one of the only original Victorian structures left behind. An electric system was chosen over hydronic to minimise the load. Situated on the original cast iron structure, the large floor is subject to high-traffic. The system was installed in three zones using a combination of 3mm cables and 160W mats. The final system provides a flexible solution for the restaurant on this iconic RIBA Stirling prize-winning pier.

Tom Smith Plumbing and Heating Services, G1 Installers who specialise in renewable, eco-friendly technologies, completed the installation of a hattrick of Grant products in a new build property in Perranporth, Cornwall. An Aerona³ heat pump, Wave cylinder and Uflex underfloor heating system are working together to fulfil the heating requirements of this new family home.

To provide high quality instantaneous hot water, the developers were persuaded to move away from a conventional recirculation system to the higher efficiency single-pipe solution, using nVent RAYCHEM HWAT-M self regulating cable and the unique nVent RAYCHEM RayClic connection system. In addition, nVent RAYCHEM T2Red and T2Reflecta underfloor heating was used in the main living areas. The self-regulating cable could provide very responsive heating without overheating, thus avoiding damage to the high quality wooden flooring. Underfloor heating was also used in the bathrooms, using nVent RAYCHEM T2Quicknet. All fully integrated with the BMS to avoid individual controllers.

The building was constructed using ICF blocks that are to have a rendered finish. Internally the ground floor is a concrete slab and the upper floor has timber posi-joists with the Lewis Deck and resilient strips laid above. 16mm underfloor heating pipes are then clipped into our new clip rail system with a free flowing screed then poured on top, 50mm thick. This then gives 20mm cover to the heating pipes, maximising the efficiency of the whole system.

The facility will convert 300,000 tonnes of household waste to electricity and hot-water. The structure incorporates a ramp for vehicles to access the incinerator entrance. Contractor Sir Robert McAlpine approached Heat Mat to supply and oversee installation of a ramp heating system for the entrance, allowing year-round access. Specialist constant-Wattage cables with 10m cold tail connections were installed beneath a 210mm concrete and rebar slab. Dual-zone thermostats will control them, and external sensors will monitor conditions for maximum efficiency. Heat Mat will return to the site, due for completion in late 2015, for final commissioning.

Heat Mat’s technical expertise helped to deliver a luxurious and low-energy heating system for a Passivhaus development in Tankerton, Kent. Oyster Reach is a group of contemporary apartments with views over Whitstable Bay. The small energy-efficient development is designed and constructed with a ‘fabric first’ approach to meet ‘Passivhaus’ standards. Masonry Frame Systems, builders of the mixed development, approached Heat Mat to provide a flexible and energy-efficient heating solution for the five apartments.

In Manhattan Loft gardens, they have a dry install system and are going to use the recommended system from Sika, then fit the floor fully bonded with our SW890 adhesive. Installation and site visits are part of our service. With large residential tower developments, there will normally be slabs for each floor. These will take at least two years to dry out completely. This means that unless the slabs have a DPM applied there will always be a chance of moisture affecting whatever is laid on the floor be it a cradle system or dry install underfloor heating system.

Neo-classical building with a stunning Portland stone façade and colonnade. The underfloor system features on seven floors of the eight-storey building. The system is a CAM-C Direct Expansion system with supply and return air distributed via the floor plenum. The Fantiles are standard TU4 fan terminals with EC motors. Instead of a rooftop chiller providing chilled water, the building uses heat pump units to maximise use of space and energy efficiency. The project was delivered as a ‘Shell and Floor’ development to allow the incoming tenant to complete the fit out works to their own requirements.

With outdated electric storage heating in all 72 flats, Places for People knew that heating system upgrades would reduce bills and improve comfort for residents. TMS Electrical Contractors Ltd, based in Rudgwick, Horsham, was instructed to specify the most suitable replacement – and Dimplex Quantum was the obvious choice.

The development is one of the most modern office centres in Riga, refurbished in 2009 to A-class standards. The building of 16,000 sq m comprises six floors of offices and a multi-level underground car park. Latvia is well known for its fluctuating weather conditions and the underfloor air conditioning system was specified to provide heating and cooling for the building due to its ability to cope with these fluctuating demands, whilst maintaining optimum low energy performance. Awarded most Energy Efficient and Most Sustainable Building in Latvia 2011

Completed in June 2020, the high-end refurbishment and extension of this 1930s warehouse and former clothing factory has transformed its interior space into six floors of premium, light, airy, and flexible workspace. Harella House has received a BREEAM ‘Excellent’ rating, and it is estimated that the refurbished building achieves a 47% reduction in carbon emissions. The ceiling heights and original windows were key features to be preserved during the refurbishment, and one of the key advantages of AET Flexible Space’s underfloor air conditioning system is that all equipment can be installed beneath the existing raised access floor, and there is no need for a lowered ceiling. Reducing the building’s energy consumption and carbon emissions were key considerations for this project, and AET Flexible Space’s underfloor air conditioning system was selected for its low environmental impact and high efficiency. All heating and cooling in the building is provided by a high-powered heat pump system. Working with the architects, Piercy&Company, and consultant, Elementa Consulting, AET specified its CAM-C underfloor air conditioning system. AET’s CAM-V system and TU350 slimline Fantile™ units were later specified for the fourth-floor mezzanine. The slimline Fantiles™ were specified on the mezzanine level to accommodate the very low floor void, and allow for maximum floor to ceiling heights. Across all floors, chilled or warmed air is provided by the conditioned air module (CAM). The underfloor void is divided into supply and return air channels, and supply air is drawn up into the space by Fantile™ units. Air travels back to the CAM via return grilles, which are located at floor level with the CAM-C system, and at high-level for the CAM-V system, where it is reconditioned and is mixed with fresh air to achieve high standards of indoor air quality. The internal layout for Harella House needed to be as flexible as possible, which was another reason why AET’s underfloor air conditioning system was specified. AET’s Fantiles™ are recessed into the 240mm floor plenum, and can easily be moved and repositioned, depending on changing office layout. This gives the end-users of Harella House increased flexibility and control over their workspaces, without the costs associated with repositioning fixed, ceiling-based systems.

M&E contractor ‘The All Group’ designed 2.5km RAYCHEM of HWAT-M self-regulating cables in a single pipe hot water system throughout the hotel. Controlled by RAYCHEM HWAT-ECO smart controllers, the system provided the benefits of energy efficiency plus savings in material costs, labour and space. Pipe freeze protection was delivered using 5.5 km of RAYCHEM WinterGard, controlled with RAYCHEM RAYSTAT-ECO-10. Underfloor heating was installed in the bedrooms, using RAYCHEM T2Red with T2Reflecta. In addition, RAYCHEM T2Quicknet 160 was installed in the en-suite bathrooms and the hotel’s luxurious spa.

Built on a self-build development site at Graven Hill in Bicester, where every property is different, this house utilises a number of different design styles and is constructed from an ICF system called Durisol Blocks. The first floor is constructed using the Lewis Deck and includes sound separation, underfloor heating and wet-rooms. It is common for the 1st floor to see a liquid screed installed over the deck, however for this project the client just ordered a little additional of the concrete being poured down the walls to complete the floors.

Rolling stock yard is a new landmark development offering 57,500 sq ft of contemporary office space designed by world-renowned architects square & partners. Colorminium appointed Volka Fitzpatrick as the main contractor. Aztec Screeding Ltd based in Gerrards Cross where awarded the screeding and resin package for the project. Aztec Screeding approached Longfloor liquid cement screed and their distributor to discuss the requirements for the ground floor reception area, which required a robust early drying liquid screed to be installed over water fed underfloor heating system at an average depth of 50mm.

An energy efficient approach to construction, using low maintenance building materials together with Dimplex ground source heat pumps, is proving the key to cost-effective heating at a collection of ten new homes built by Shetland Islands Council in Brae.
