Design considerations for wet underfloor heating

Wet underfloor heating circulates heated water through pipes beneath the floor. Its suitability depends on the room’s heat requirements, insulation and floor build-up, so a floor area alone is not enough to select a system. Share drawings, room dimensions and information about the existing heat source where available. Let us know whether the work concerns a new extension or an occupied room with a finished floor.

Floor levels and finishes need early attention. The pipe system, insulation and any screed or overlay must fit the construction, while the chosen floor covering must be suitable for the intended operating conditions. Door thresholds, kitchen units and other fixed features can also influence the layout. Avoid finalising floor heights or ordering finishes until the relevant requirements have been checked with the people responsible for the design and installation.

Controls and zoning determine how individual spaces are managed. Underfloor heating can respond differently from radiators, so handover should explain how to operate the agreed controls. Where radiators remain elsewhere, our central heating service can help consider the combined system. For impartial background on heating choices and controls, visit the Energy Saving Trust. Running costs depend on the property, heat source, tariffs and how the system is used; savings cannot be assumed for every installation.
