when i bled my radiators at the weekend it seemed to empty the boiler. So i used the filling loop, but didn't turn it off soon enough. The system pressure gauge is between 2.5 and 3 bar when it's off, and 4 (maximum pressure reading possible) when it's on! I've bled a pint or so of water out of the radiators but it hasn't made a lot of difference. Should I just drain some more? I don't seem to have access to the pressure release valve, and can't see where it would discharge. Is the central heating return meant to be closed?
It's a gas boiler, Worcester Bosch 240 Combi RSF. Previously i was having problems with the thermostat cutting the pilot light after the (very) hot water was running for a while, I would use the overheat thermostat reset button to turn it back on.
