radiator pipes

[bricktop2]

Hi
i want to put a new radiator in my kitchen and would like to put the pipes in the wall, its a red brick internal wall. Can i just plaster over them or do i need to wrap them in something?

Thanks in advance
Wayne

I know it's a lot of work but if you're using microbore (8mm or 10mm),
the best way is to channel out the wall for plastic wire trunking (the white plastic stuff used to hide electrical cables) and run the pipes in that. It protects the copper pipes from corrosive elements in the plaster and it just makes a better job of it.

If not then yes you must wrap the pipes, again to prevent corrosion from the plaster.

Plaster doesn't attack copper, unlike cement. But if plaster gets hot it will crack, and if pipes are held tightly they will move and crack whatever's holding them, or any joints.
