Can microbore copper pipes be installed into a concrete floor?

microbore isnt really designed to be used as underfloor heating, as there can be a lot of bends to get around the room, your best to used the correct set up with blending valve, manifold and barrier pipe or the heat will crack the floor very quickly, cement eats copper within months if unprotected, hope this helps

yes, they must be wrapped,fully tested to temp,and i wouldn't advise plastic pipe with fittings within the slab if you are burying them! they must be away from cement,concrete etc I firmly advise you to get a good gas safe plumber in and get it done properly! are you putting inhibitor in your system? can you re-fill system? balance your rads? if you don't know about putting pipes in floors i suggest you leave it to a professional, and he mite be able to do it for you on your budget. aint really a DIY Job! post it on here kieran
