Hi im looking to fit a radiator in a bungalow kitchen as there is nothing there at the moment all the walls are solid so im going to put a channel in the wall from the loft to run the pipework to where the rad is gonna go the pipes are going to be plastered over then. Just wanting some advice on the best way to go about it im thinking of using 15 mm plastic pipe in the wall and then put 10mm microbore in the plastic to stop the copper corroding because i dont want any mechanical or pushfit joints in the wall and microbore will be more flexible just wondering if this is the best way to go about it or any other ideas?
