I live in Wisconsin and want to heat the main floor of my home with a free standing wood stove. It is just under 800 sq. ft. I have been looking at Us S tove APS1100B and the US Stove 2000. I'm afraid the 2000 is to big as it is rated up to 2,000 sq. ft. but the APS 1100B might be to small and not keep a fire all night. The 2,000 has more features like the ash box and air intake damper. I'm confused how the air intake works on the 1100B as it is above the fire. Any help would be appreciated.
