Why don't more oil burners use outside air?
I was just wondering why more oil burners do not use outside air?
I know in wood stoves and some fireplace designs, an outside air tube is used near the combustion to minimize drawing cold air through the home.
I know there are kits available, but from my limited experience with oil heat, I haven't seen many.
Why don't more oil boilers use this?
