central heating
CAN ANYONE ADVICE PLEASE
My central heating pilot light went out I called an engineer who said that the condensor had gone he replaced this but then found the pilot light still would not stay on so he changed the part that keeps the pilot light on , the gas flow unit I think it was called. This seemed to work but i then found the burners where not turning off hence the water and radiators where getting far to hot. Gas engineer could not find reason why this was happening because the thermostat seemed to be working ok. Another gas engineer came out and found that the thermostat did not fit flush into the tube in the boiler so this was recording cold instead of the proper heat. Problem was the original installers had fitted this in by a screw to make the thermostat touch the metal to give a reading to the thermosta. Problem I have now is although the burners are now turning on and off the radiators are still getting hot on the low setting. Does anyone know what the problem is.

From what you describe does this mean there is a problem with the pump. My system is 18 years old. Fitter tells me it is still in good working condition and is baffled to what is wrong with it. He has eplaces the thermostat.thermo coupling and something to do with the pilot. It is truning on and of now but the radiators are far to hot even though it has been set at a low reading. l
