Hello all,
Does anyone have previous experience of noisy Potterton boilers (Promax Ultra Combi 28 ErP)?
Intermittently this will let out a deafening long howl after it reaches temperature (immediately prior to the howl it sounds like an aeroplane descending). This can come and go during times of constant heating or hot water use. Turning off the thermostat or hot water stops the howl immediately.
Attached a minute long video:

Suggestions of a likely part that needs replacing?
