Underfloor heating advice

Question

Hi. I’m hoping to have underfloor heating installed at some point. I just wanted to learn a bit more about them first. For instance, is it possible for a UFH pipe to leak beneath my floor and what precautions could I take to a) reduce this risk and b) be able to detect/know that this is the case, should there be an underfloor leakage? Thanks for your time.

You shouldn’t get any leaks as there should be no joints under the floor. If the underfloor heating is pressure tested and left whilst screeded then you can monitor the pressure gauge if needed.

Dominic · Answer

It will only leak if there are joins, you use a whole piece of pipe the only join should be to a manifold which is not under screed

Shaun · Answer

possible I suppose, but it's not common for the underfloor pipe to leak unless it is damaged in some way.

Matthew Martin · Answer

UFH pipe should be done in 1 continuous length of pipe

Mal · Answer

There should be no joints in an underfloor heating circuit. This eliminates leaks unless someone puts a screw or nail through the floor into the pipe

Chas · Answer

Always use 15mm and above pipes no joints under floors only at the manifold and make sure Always laid on specific material for floors make sure Always laid by competent traders

Kris · Answer

Underfloor heating is piped in zones with no joints under the floor so the only way it will leak is if the pipework gets damaged ie someone puts a screw through it, I hope this helps
