Over the years Nu-Heat has been asked to design systems incorporating every conceivable type of heat source. As a result, we are considered market experts in the integration of underfloor heating with new and emerging technologies as well as traditional boilers.

With fuel costs on the increase it is more important than ever to install an energy-efficient heating system. The low system water temperatures of underfloor heating will enhance the efficiency of condensing boilers and give fuel savings of typically 25–40% (source: BSRIA). Even greater savings are achievable when a heat pump is used as they operate most efficiently when used in conjunction with underfloor heating.

As the heating emitter is so much larger with underfloor heating than with radiators, water temperature within the system can be much lower. This ranges from typically 35–45˚C, compared to 55–65˚C for radiators. Low flow temperatures are ideal for heat pumps as they enable the maximum efficiency of the units to be achieved.

Nu-Heat also offers a flexible renewables package of integrated heat pump and solar collector(s) that will cover the heating and domestic hot water needs of a wide range of properties.

Heat sources suitable for use with underfloor heating include:

• Ground source, air source and exhaust air heat pumps


• Solar thermal collectors


• Gas, oil and electric boilers


• LPG boilers


• Biomass wood pellet boilers


• Micro Combined Heat & Power units (MCHP)


• Cooker boilers (AGA, Rayburn, etc)


• District heating


• Combinations of renewable sources and traditional boilers
