Its that time of year again when things make strange noises with the heating!
Our boiler has been fine all summer so I have now determined that it makes a strange buzzing noise when the heating has been on (as apposed to just the hot water). The noise happens only when the boiler has been on then goes off (when room is to temp). Any thoughts on the cause? I'm thinking pcb.....?
Many thanks in advance
