Gas Pipe in screeded floor

[jon26]

What are the current Gas Safe regulations for installing copper gas pipework beneath the screed? Is there just a requirement to wrap in protective Denso tape.

Are joints or connections an issue under the screeded floor?

Are there different regulations if the screed also contains underfloor heating?

I am obviously not an installer but curious to make enquiries before I appoint an accredited gas installer.

Any comments would be appreciated.

Regards.

Denso is best.

Joints should be avoided.

If you thinking electric underfloor then the gas pipe has to go elsewhere.

Thanks, I was meaning wet underfloor heating.

Regarding the joints, the 3m length copper pipes would need to be jointed, so there is no way round this I assume?

Or I may be wrong here

The engineer can buy 6m lengths or better still 20m coils of soft copper

Good stuff. This is all well and good, but what happens if joints are unavoidable or not practical?

Cappillary joints are not barred in a screed. If you wish to be jointless, you an buy rolls of semi flexible 15mm tube, pre warapped - but itl is more expensive:

Gas advice is not to be given on this site, so that is about as much help as we could give you. Are you using a Gas Safe RGI?

Thankyou for the info

The ACS answer is now "Petroleum Jelly impregnated Tape" but that probably changed since you took your last assessment!

As far as I can see the gas pipe could still go in a floor with an electric heating element as long as it was at least 25 mm away from the wire. ( Unless there is a specific regulation I have overlooked. )

But your installing RGI should know all about this and advise you.

When we see DIYers asking this kind of question we naturally wonder if its intended to be a DIY job which, with gas, would be potentially very dangerous!
