Hi,
We have a Vokera Syntesi 25 combi condensing gas boiler.
The boiler was fitted four years ago: it was moved 2.5 years ago when we built an extension.
The hot water works fine.
The heating generally work fine. However, if we have the heating on then as/after the system cools down the system loses a lot of pressure. Typically we have to top it up twice a day.
The obvious answer is that there is a leak in the central heating pipes. However, before we start rippng up floors (including an expensivenew Karndean floor) I would like to make sure: i) its not the boiler and/or ii) explore other options (Radweld for central heating?).
A couple of plumbers have just assumed its a leak - but they didn't inspire a lot of confidence.
Using Google I found two interesting posts.
One mentioned a bleader valve or similar on the pump.
The other mentioned a possible leak in the expansion tank.
Any suggestions to help diagnose or fix the problems would be gratefully received.
Yours
Douglas
