The pressure on my worcester 24i junior combi is running way too high when using the central heating and is rising to over 3 bar!
Did a bit of research on the forum and tried pumping the the expansion vessel with air.
I did this by draining the system so that the pressure was down to zero, then pumping the expansion vessel to 10psi, then pressurising the boiler to 1 bar. Then i switched the boiler on but pressure still rising above 3 bar within the space of a few mins.
Any ideas what the problem could be?
