Radiator pipes into a wall

Kellez

Hello everyone,

I am renovating a house and i would like to hide one set of radiator pipes inside the wall. The radiator is at ground floor therefore pipes are coming down from the ceilling.

I want to use speedfit layflat 10mm pipes so as to keep the depth of wall chiseling to a minimum.

Can anyone guide me through this process? I know how to do this if the pipes are not inside the wall but i am unsure what to do when they have to be burried.

Its a brick wall with cement on top and a very thin layer of plaster.

I have already chased the wall behind the centre of radiator but still needs some depth to it. However in order to decide how much more depth i need i have to know exactly what is going into the wall.

Thank you everyone

Do you think i have to use a pipe conduit so as to protect the pipe (provide room) when expanding?

Try to avoid any joints within the buried pipework for obvious reasons

I'd use some sort of conduit.
What i've done here in the lounge is brought the pipes down in the corner of the room and hid them behind ceiling coving going vertically Then decorated over that.

I will try to, but i think it would be really difficult since the pipes are not going straight down (vertical) from the ceiling. The chasing is an L shape, do you think i could be able to bend the pipe at a 90 degree angle without any joints....i am using the speedfit layflat polybutylene???????

What do you think is the best option to connect speedfit pipes to radiator valves?

1) use stem elbows (i dont really know how this are used)
2) or just insert a copper olive on the speedfit pipe with a compression fitting and connect it directly to the radiator valve?

Sorry but this whole idea sounds like a definite no, no, and you won't be able to put a 90 degree bend in poly pipe, it'll just kink.

When I built my present house I ran all the heating pipes down the wall from above. I sunk some rectangular trunking into the wall and arranged the depth such that the trunking lid was just covered by the plaster skim coat. So if access was ever require it would be easy to get to.
However, in over 35 years no access has ever been required. The pipes were 10mm copper microbore. I might have required a larger trunking if I had used 15mm pipe. But it was so long ago that I cannot say for sure.
I was cutting through soft blocks. Brick would have been a different kettle of fish. Though nowadays the are plenty of electrical tools which would make the job easier.

You dont really specify why this is a no no idea.....and i think you are wrong about the 90 degree angle. I already bought the pipe and it can bend at 90 angle with no problem......there are even special fittings for this purpose called cold forming bend.....see the link below

i am going with pipe conduit and i hope i manage to get a good 90 degree angle with an outlet box behind the radiator
