HI all can anyone plese help i have a servo warm elite boiler i have had to change the water cylinder and have had to alter the pipe work around the pump and the 3 way valve .
I have filled the system and the central heating side is working fine, however when i put just hot water when it starts up there is a banging noise and rattle from the pipes also whilst this was happening i nipped up into the loft and found air was being pushed up into the header tank also felt some hot water the noise stops but the cylinder does not get hot?
