Ravenheat RSF820 Knackered Expansion Vessel

[mikedelderfield1]

Hi

Erm

I have a problem with the above combi-boiler, which ocurred yesterday.

The pressure on the central heating system exceed 3 bar, which tiggered the pressure relief system. I had a similar problem about 12 months before, which a plumber fixed for me and was caused by insufficient pressure in the expansion vessel.

I have just checked the pressure in the expansion vessel and a fair amount of water leaked out of the valve. My understanding is the expansion vessel should contain air only

Do I have a leak into my expansion vessel? Is it terminal? Should I send this boiler into boiler heaven/hell?

Any help would be most appreciated.

you can replace the vessel
or fit another on the system

Ah yes forgot about that as a possibility.

Many thanks for the suggestion.
