    It's a brand new boiler - 3 months old. The code says S.04 heating mode burner on but the burner indicator is very low power. It runs like this for hours. Thank you

    We seem to have a problem - when the boiler reaches flow temperature it shuts down and then restarts and hangs around 40 degrees flow temp. Any suggestions please?
