Idk about stove brands, but when I lived in Massachusetts my best friend had a lake side cabin with a bunk house. This was very primative. The bunk house was about 12x20 and had a tiny metal box stove (12x12x24). And that thing could turn the bunk house into a sauna with 4-5 prices of wood. It slept 10-12 people, so not a tiny bunk house.
