Thermostat off, burner runs anyway
saxpoet Member Posts: 1
I'm new to steam heat. This is a 5 year old Burnham, single pipe system. Hot water is an independent electric heater. Ever since putting the programmable Honeywell thermostat to 'off, the burner still fires up and runs a few minutes at a time, more than once a day. Is this normal?
@SuperJ has a point. Was the boiler ever used to produce DHW?
If not then follow @STEVEusaPA advise0
Look on the right side of the boiler. Is there a grey rectangle control? Pull the cover and turn the temp to 140.
If its oil fired, it's not a bad idea to have the system cycle to keep the flue passages dry.0
