Hi people
I have had a compact HE boiler for some 12 years now and all in all its been OK just a couple of issues that have been quickly sorted via engineers.
Today when i tested the central heating for the first time since last winter it sparked up fine and heated the rads OK but the pressure gauge upon checking had shot so high that the blue indicator wasn't even visible.
Upon seeing this I turned the heating off again via the room stat and bled my bathroom radiator of enough water to get back out of the red zone again. The boiler has since cooled and lost so much pressure that it red lighted and needed resetting.
Now I have had the expansion vessel changed already on this boiler a couple of years back for this very problem so can it really have gone again??
I have had a good read up here about "recharging" the vessel via a handpump and am willing to give this a try if you guys think that is what this could be and I have even had a look already to find the valve at the top and check there is no water coming out when you press the centre of the valve (there isn't - just air).
So could this be my problem and is it worth a try should I ring a gas safe guy again?
Any advice appreciated.
