Hi i had a new system boiler and tank fitted a couple of years ago with an eye to an extension i was planning. I had the supply and return pipes to the future extension radiators terminated with gate valves(22mm pipe) under the floor. I plan to run in the two radiators for the extension myself so heres my question.
How do i find out which is radiator supply and which is return?
Also should i run in a single copper supply(10MM) pipe from the supply gate valve to close to the radiators and T off to both thermostats from there or run in two seperate pipes from the gate valve to each radiator(same question for the return pipe).
At the moment i can only see me putting the heating on and see which gate valve is hotter to decide which is supply and which is return.
Thanks for any help.
