How Do Water Underfloor Heating Systems Work?

Water floor heating systems feature pipework installed below the floor’s surface – either within a layer of screed or on top of floor heating insulation boards or panels laid on top of the subfloor – through which heated water is gently pumped, radiantly heating the space above.

Manifolds are a crucial part of all hydronic underfloor heating systems. They connect the floor heating pipes to the heat source, such as a gas boiler, or ground-source / air-source heat pump, helping to circulate heated water through the system and warm the room above.
