I am planning to move a radiator from one wall to another (swmbo's idea). All the pipe work under the floor is 10mm copper. It is a two pipe system and the pipe runs will be shorter when I am finnished as the feed under the floor will be closer to where it comes through into the underfloor space. I know I will have to drain the system before I start. Any thoughts on what problems I might encounter with the refilling etc. Is it ok to shut the rest of the rads off so I only have to drain the pipework?
