My girlfriend has a problem with her central heating boiler banging. It's a Baxi boiler, I'm not sure of the exact model but its about 20 years old.
Anyway shes got the system on hot water only at the moment and it starts to bang when it's been on for a while and the banging appears to be coming from the boiler but it ressonates around the house via the hot water pipes. We are guessing the problem is with the water heating rather than the CH as it does it with the CH off.
I'm guessing this is likely to be caused by an air lock somewhere in the hot water system but any opinions and suggestions would be welcome.
