I have recently removed a radiator so that the room can be decorated. Throughout having this radiator off the heating system has still been functioning but the pipes seemed to have started banging. I have now put the radiator back on but the banging is still there and wakes my kids up in the morning. This banging occurs all the time when the heating is on and not just when it is firing up. I have no leaks and the pressure in the system seems ok? Is it worth bleeding and repressuring the whole system as I have removed a radiator?
