Plastering central heating pipes into wall

[siward]

Hello All,
I am hoping to hide some unsightly 10mm microbore CH pipes in a chase in the wall, and cover in plaster.
Does this ring any alarm bells with anyone?
Should I provide any expansion room?
Many thanks for any help.

Should I provide any expansion room?

Yes. You can buy flexible conduit designed for the purpose.

Or you can use some old hose pipe split down the sides, which is what I do! Or maybe bury it in expanding foam, trim of excess and skim over?

I don't think a proprietary conduit will be suitable for fitting without being able to slide over an open pipe end.
