Hi
I have a 4 yr old Britony Combi Chaffoteaux & Maury wall mounted boiler.
This morning at 5.30 a.m. when heating cuts on it started howling/moaning at high pitch. So I turned it off.
This evening I have turned it on and the problem is still there !!
HOT Water Only - it howls and pressure 0.7 bar.
HOT Water and hot tap over half on no Howl and pressure stable at 0.7 bar
Central Heating on (need it cos flipping cold !!) and it Howls and pressure drops to 0.1 and still goes - howls a bit more high pitched I think ....
So Turned CH off -
Any thoughts - and if so any ideas which knobs do what ??
Thanks
