My boiler packed up 11am yesterday after 21 years problem free heating.
What happens when I switch it on is:
The fan starts, the boiler then fires up and works for about 2 minutes and then the flames go out but the fan is still running.
If I turn it all off for half and hour it can then be restarted and runs same again for 2 mins then nothing.
Just enough to warm the tails of the nearest radiator (hall), which makes me think my pump is OK.
I'm thinking this may be thermostat related.
Potentiometer or Overheat thermostat but that said the overheat reset button hasn't popped out at all.
Two months ago, I had two radiators replaced, all radiators balanced using a thermometer to check difference in the flow and return temperatures
and the system was flushed through and Fernox inhibitor added.
Any advice or confirmation welcome please.
