Can anybody shed any light on this for me? I have a 17 year old baxi Bermuda back boiker, never given a bit of trouble in all that time, although at the moment, after the pilot has clicked off, the boiler seems to rumble like its boiling, it can be heared through the radiators around the house when it does it, BG have looked and said there was no fault, but it only does it when the boiler has been in use for some time. Alsi does this boiler cone with a control panel for the burner etc? Can't see one but it may be tucked behind in the chimney breast. Thanks
