I have a Ferolli F24 boiler.
After about 30 secs of starting up the central heating a loud banging noise occurs (sounds like its coming from pipes into boiler).
The banging noise lasts about 10 secs and then the boiler makes a buzzing noise. The central heating still works okay.
The banging noise occurs everytime the heating is turned on however the buzzing noise sometimes doesn't occur.
I recently let air out the rads and re-pressurised the system.
I also recently had to turn the stop cock off to fix a tap. I think the banging noise may have started after turning off the stop cock.
Any suggestions on what the problem might be?
