Any advise gratefully accepted
I have a Myson Apollo boiler, a Wilo Gold 50 pump, Honeywell mid position valve and Danfoss timer, recently i had to change the Honeywell valve and ever since when the heating turns off when up to temp on the room stat there is an almighty water rushing sound through the pipes and they bang and rattle. The radiators upstairs get warm but a couple downstairs are only aired and not as hot as upstairs.
I have bled the radiators, adjusted the settings on the pump but still get this problem every time just on the central heating.
Any ideas ??????
