Still having a problem with the heating. So far I have checked the pump, the 3 port valve, the thermostat on the boiler, the gas vale and room stat. All of these are working fine but the radiators wont get hot and there is no hot water. Everytime I drain water from the boiler it cuts back in (the water drained off is always hot) If anyone has any ideas I would greatly appreciate it. As Im in the construction trade I dont like to not bring a heating engineer in, I would rather try an save some money
