Hi,
My boiler has stopped firing when the temperature has dropped below the point when the thermostat should kick in. The boiler does however fire when the water cylinder drops below a certain temperature and the thermostat on the tank kicks in. When this happens the radiators heat up during the period that the boiler is on heating the water, but not to the temperature you would expect.
I have a Danfoss thermostat ret230p. When I adjust the dial it clicks but the boiler does not fire. I am unsure whether this is a failure of the thermostat, a motorised valve, the boiler itself or something else. My thoughts were that because the boiler doesn't even attempt to fire, that it is not recognising the signal from the heating thermostat, but then again, why do the radiators go warm when the boiler heats the water cylinder. Any help would be appreciated. Thanks.
