We have a Glow worm Betacom 30 boiler, over the past few weeks it has been getting noisy (intermittently) when the heating is on, it's OK when just hot water is used. The noise is vibration that gets transmitted through the pipework so you can hear it throughout the house. It seems to be coming from the pump, has anyone else had this as a problem?
Is it worth stripping the pump to try to cure the vibration?
Cheers in advance.
