Underfloor heating can be installed in various types of floor construction, typically pipe in screed, however other methods are available e.g. pipe in plate. The floor construction and floor coverings will ultimately affect the efficiency of the system with the pipe in screed and a tile finish being one of the most efficient combinations. Bear in mind that thick carpets and divan beds etc. inhibit the transfer of heat from the floor into the room and are not a good combination with underfloor heating.
Control of the flow temperature and flow rate through the underfloor heating manifolds and pipes will dictate the room temperature. Control can be managed by the heat source like a heat pump, for example, or by room stats controlling the flow of heat to each room /zone from the manifold system.
Underfloor heating is now the system of choice in new homes and can also be retrofitted providing that the level of insulation in the building means that the desired room temperature will be achieved. Heat Solutions works this out as part of the system design.
