I moved house just over a week ago and until last night I hadnt used the central heating. I've been using the hot water system which works fine, although I noticed that the radiators were getting warm when the hot water comes on so i turned each of them off via the valve on each radiator. Anyway last nite I turned them all back on, turned the thermostat up to max and put the heating to "on" on the control panel. However the boiler did not fire-up and obviously the radiators did not heat up, the light was on on the control panel indicating that the heating should be on. However, switch the hot water on & the radiators started getting hot again. Can anybody help me to get the heating working on the heating control! The boiler is a Potterton Suprima and the control panel is an ACL Lifestyle Model LP241, both about 6/7 years old. HELP ME PLEASE!!
