I had a microbore based central heating fitted a few years ago, severa
of the pipes are on the surface
I now want to bury the pipes in the wall but know that there ar problems putting copper and cement / plaster together.
How should these pipes be coated or wrapped to stop problems
Thanks in advance

Cu will corrode in cement, but I don't think there's any such problem with plaster.
However the expansion and contraction might make the plaster crack so I'd wrap them in something - maybe the sort of foamy silvery stuff sold to put behind radiators.
If there is such, get the split foam tube usied to insulate water pipes.
Or just wrap them in foam tape?
Anything that allows expansion and keeps wet plaster off.
You cxan get plastic coated 10mm copper as well.
