Just removed a radaiator fro a system with an header tank,cwc and cylinder(indirect). I capped off the pipes and refilled the system. when the system was full the cylinder and cw tank made quite a loud vibration noise. when we run a bit of hot water off from the taps the noise slowly stopped. can anyone tell me the cause of this noise. Also the rad doesnt tee off to another so assuming last radiator will there be any circulation probs with these pipe deadm legs.
