ye think that might be the case cause i took the pump off and it is indeed broken the fan part has seperated from the pump. ordered a new 1 for 40 quid so not too bad. cheers for the help, keep up the good work
just put a new radiator in the bathroom and bled the system of water to put it in.
Problem is that when i refilled and turned it on the pump was making a heck of a racket and only the downstairs radiators were hot. I bled the system of air via the radiators so radiators hav no air in them only...
