Hi looking for an opinion, I got a large radiator in a room that has already got one and that is surplus to requirements. I like to remove this and installed it in another room which has only got a small radiator.
My system is a non-pressurized one with a standard oil boiler, can I just remove the radiator cap the ends and extend the upstairs pipes to fit the new size, or do I have to connect the in and out pipes and drain and refill the system?
