Hi, My central heating is not fully responding to the controls - if I set them to 'on', so there is no timer involved, then it causes the burners to startup up but they turn off within 10 seconds. Is this due to faulty controls auto turning off the burners or something else such as an air lock...

Along time ago {10/11 years ago?} the government announced 5 % vat on energy saving improvements to central heating systems. I used to get pestered by the Corgi Vat saver company but never took it further, earlier this year I heard they were involved in a test case with HMRC. Does anybody...

Ravenheat CSI 85 CH water suddenly running greatly hotter. Does ignite on/off on CH thermostat/potentiometer manual control knob - but CH water temp. does not reduce by this control knob (as it did). With high temp, water pressure can increase from 1.5bar to near 3bar - pressure relief valve...

I have just moved in to a propery with an oil fired boiler. The name on the boiler is Boulter Buderus and the name on the controls is Camray 5. There is no handbook. When comparing it to a neighbours (slightly different) system it would appear to be using at least 3 times as much oil as it...
