Boiler has begun restarting when central heating is on. I put central heating on and after 15mins boiler goes off and restarts again. This is continual. Pressure is ok.
Any help please
1) do you have a room thermostat
2) if not what is your heating stat on the boiler set to
3) is it the condensing version or the older model
4) is the house warm
5) do you have thermostatic rad valves
6) are they turned on
if your room thermostat is working correctly and say set to 25degrees then the boiler will fire up to temp when the stat hits desired temp it turns the boiler off and then as the room temp drops it all starts again.
The c heating stat on the boiler overrides the stat. If you are trying to achieve 25 deg and that stat is turned down it won't get to 25 degrees.the boiler will not go above the temp setting at the boiler. better to turn your boiler stat up as it will only goto the desired roomstat temp.
