Hi,
I have a problem with my Combi boiler whereby the pressure rises to about 3 bar when the central heating has warmed up but if I switch off, the pressure drops to Zero!!! If I leave the heating on it works perfectly although the pressure is high obviously. When the pressure drops I have to refill using the filling loop. I top up to just over 1 bar but again, when the heating kicks in and warms up it rises to 3 bar. Any help would be greatly appreciated.
Cheers
