I have a new Potterton gas boiler - installed only 6 months ago. It has started making a very loud noise when it turns itself on (its programmed to come on automatically with the timer), but makes no noise when it turns itself off.
The noise also starts when the hot tap in the kitchen is turned on, but does not affect the heating or hot water temperature.
A noise also comes from most of the raditators when the heating turns on, but not all of them.
What is causing the noise and how can it be fixed?
