Hi All
I tried to help a friend out today with his heating system. but failed. Basically the hot water on the system is working perfectly but the central heating is not. If you switch the whole power off to the heating system and then back on again, then switch the central heating on, the system powers up, pump goes and boiler fires up. After about 1 minute it goes off. The pump switches off and the boiler stops. The room thermostat is on to max temperature. The radiators are standard rads with no thermostats. If you switch the hot water on, it all fires up ok but does not heat the radiators. The boiler, is a Vulcan boiler. The switch unit is by Thorn Emi. I'm not sure of the model details.
Any help on the matter would be very much appreciated.
