Fizzing Boiler.

Hi Everyone,My Potterton Puma Combi Boiler is making funny noises. They are like little fizzing noises and sound like(this is just a guess)water hitting a hot pipe or something and quickly turning to steam.Could it be due to the hot weather we are having?
Any ideas received with thanks.

I am not a pumber or heating engineer so wait and see what others say, but it sounds like you have a leak and the hissing you hear is water being boiled as it hits something hot, but as i said DON'T worry wait and see what others say (but as its Sunday it may be a while)

I am a qualified plumber and Corgi registered heating engineer, have degrees and qualifications in all sorts of things and like helping people.. Bet you're glad I'm answering, heh?


I haven't a clue what your noises might be, apart from the obvious, which includes water in the electrics. So I have to advise you turn it off and call someone out.

You'll never learn if you don't ask
