I have glowworm 55f boiler with potterton EP2000 controller switch .The radiators all have microbore pipework.
The central heating fires for about 1 minute and then cuts out.
System worked when we moved in 2 months ago,since then I have had to shut off the hot water from the main hot water tank and also the cold water mains supply.
Could I have induced air into the system?
There is a pump under hot water tank which appears to be working and I have bled radiators but they seem to have no air in them, any help gratefully accepted as I am only used to combi boilers which we had in previous properties.
