Would anyone be able to advice what the likely source of a intermittent metallic sounding knocking or banging noise from my boiler could be please?
The boiler is 18 months old and had its first annual service when due. I did point out this issue during the service but there was no evidence of the issue at the time.
Any help or advice appreciated.
