I have a Glow-worm Fuelsaver 35F. When boiler lights up, and the temperature dial is above 2, there is a shrieking sound coming from what seems to be one of the two water pipes out of the top of the boiler. When dial is below 2, there is no shrieking. Does not matter if I have heating on or hot water, it does it just the same for both. The sound can also be heard through the bathroom radiator, but no where else.
All radiators are equally hot, no problem there, and hot water is hot.
But what is causing this noise.
I have had no problems with it for the past 12years.
