I have 1800 sq ft colonial house. There is a spot in the unfinished part of the basement where they previous owners had a coal stove. They "said" it heated the whole house, 80 in the basement, 70s main floor and 60s second floor, where the bedrooms are. Each floor is about 900 sq ft. There are three grates installed going up to the main floor. It isn't an open floor plan, but the kitchen, dining room, living room are all in a circle so there are open doorways all round. And the second floor has an open stairway, no door. There are four bedrooms upstairs, but they are small. Is it crazy tot hink the right sized stove will heat this all from the basement? I just want to know what I really should expect from a stove before I decide to buy one. Thanks!
