Hi

Pls help

I'm going to be installing UFH in an extension for the 1st time.

In the area I will also need to run hot, cold & gas pipes.

Question I have is can the pipes overlap, I can't see away of doing it without the pipes overlapping?

These would be run under the insulation. Insulated hot and cold, with gas being either plastic coated or trac pipe in one piece.
Or run them over the top.

Try to keep the hot and cold pipes as far apart as you can and lag them both to eliminate heat transfer from the hot pipe to the cold pipe. Make sure the the pipes especially the gas pipe is factory sleeved or run in a ducting and does not come into contact with the screed.

What material do you plan to use?
Do you have the tools to test the pipes before covering?

If I run these under the insulation, would you suggest chasing the insulation, otherwise the insulation will not be flat.

I was gonna wrap the gas pipe in denso tape, apart from Tracpipe what other pipe is factory sleeved?

I was gonna use plastic pipe for water and obviously copper for gas.
What would you recommend

I would tightness test on the gas, then live'n up water pipes to check for leaks. Again what would you recommend?

Depends how thick the kingspan is,

Could chase 2" out and lay services in there and test and then expanding foam over the top of it

Have you got someone lined up to connect the gas?
Are they happy to connect to pipes you have installed and possibly covered over?
