i have a Ferrolli 102 combo boiler and recently the boiler is squealing when the hot water is run on full, quiet when the taps aren't on full or when central heating is on. If I switch off the boiler and run the taps it still makes the same noise so I am thinking it's not gas related? Any...

I too suffered from this in it was our next door neighbours boiler. They'd had it upgraded or something and the plumber never installed the pipes with any clearance from the walls so when the boiler pump ran the pipes vibrated against the walls. I ended up going next door and managed to fit...

Hi, The external render is fine now as the cause to the penetrating damp was where a previous boiler exhaust had been patched (badly) by the previous owner so all sources of damp entry should resolved by this as I've had the entire house done rather than it being patched. Maybe I should...
