A boiler fan is a crucial safety and efficiency component that supplies fresh air for combustion and expels harmful exhaust gases (flue gases) out of the home through the flue.
This ensures proper fuel burning and preventing dangerous carbon monoxide buildup.
It starts before ignition to clear the combustion chamber and runs during operation, acting like the boiler’s lungs for oxygen intake and exhaust removal, allowing for efficient, safe heating.
