I am moving a radiator 4m across a single story extension. I haven't got access to the roof and I have a concrete floor. I am happy to route the pipe around the wall which would mean a pipe run of 6m. Should I use 22mm pipe or 15 mm. If I went across the floor it would be 4m but ruin the floor covering. I have a combi boiler. I am thinking of using copper and solder ring fittings. Any advice appreciated
