Hi all,
I have a problem with my Hot Water Boiler, it makes a high pitch screaming/ buzzing sound. I believe everything is fine as we get our hot water for shower/ bath and for heating, but it just makes a high pitch screaming/ buzzing sound occassionally.
I found that switching it off and then on again (after a few minutes' wait) sometimes stops the sceaming/ buzzing noise. (But not this evening).
Does anyone know the reason for the noise, and how to fix it?
The model of the hot water heater is Range Powermax 155 from RSA Waterheating Limited.
Thanks
Gerard
