Wet underfloor heating

Warm water runs through pipes in the floor, with a manifold and a control for each room. It works with a heat pump.

Wet underfloor heating is warm water in pipes under the floor. A manifold splits the loops, and each room has its own control. It works with a heat pump, and with radiators in the rooms that stay on radiators.

The pipes go on overlay or low-profile panels, or in the screed. On a new extension they are clipped to the insulation before the floor goes down.

What the job involves

  • Setting out the pipe and clipping it down
  • The manifold, with flow meters
  • A control for each room
  • Filling and testing the loops

What I check

  • Floor build-up, and whether it is panels or screed
  • Where the manifold can go
  • The heat source, including a heat pump
  • Each room, so the loops are balanced

Underfloor heating was part of a whole-house job in Alderley Edge. See the project.

I don't do boiler or gas work.

Questions

Is this electric underfloor heating?

No. This is wet underfloor heating: warm water in pipes, with a manifold and a control for each room.

Will it work with a heat pump?

Yes. Wet underfloor heating works well with a heat pump. I check the floor build-up and the heat source first.

Do you do the boiler as well?

No. I don't do boiler or gas work. If the heat source is a gas boiler, you need a Gas Safe engineer for that part.
