I heat a small house approx. 1000 Sq. Ft. I also heat a full block basement that is 1000 Sq. Ft. that is not insulated. And a 24' x 36' garage as necessary. I love it I only feed it once a day even in the coldest weather. They all say bigger is better but I have to disagree. If your unit is to big it will smolder a lot and build a lot of creosote. Mine is over kill for my small place I may start keeping the garage heated all the time next year with a larger heat exchanger. I only have a small single pass radiator in there now.
