Underfloor Heating

Underfloor heating - how it works


Underfloor heating works by pumping a controlled flow of warm water from any heat source through plastic tubing embedded in the floor. Because the emitting area is large, sufficient warmth is provided even on a cold winter day with no need for supplementary heating.


We can supply a complete package of high quality components including award-winning installation manuals and a full system design with bespoke CAD drawings showing all mechanical pipework and valves as well as electrical connections. Tailored manuals are provided to suit the heat source whether conventional boiler or heat pump.

Renewables Integration


Underfloor heating can be used with any heat source including standard gas and oil boilers, range cookers and renewable technologies such as ground and air source heat pumps.


Hot water delivered to the underfloor heating manifold from the heat source is blended until the correct temperature is reached. In most boiler-fed systems this will be between 40˚C and 55˚C but in a heat pump system can be as low as 30˚C, which can dramatically increase the efficiency of the heat pump. Nu-Heat will always take into account the heat source when designing a system and specify the exact flow temperature needed for each room to maintain comfort levels.
