The Drolet Escape 1500 is a good stove for people who like efficient wood stoves that burn a small, or perhaps medium amount of firewood. I don't think that you could heat more than 500 square feet with this heat source alone, but it has been great heating that much even in temps close to or under zero. Enough to have to open windows to maintain a comfortable temperature when it's 32F out. I prefer N/S loading it with around 10" split logs and topping that with full width split logs (16" perhaps). If I had to buy another stove to heat an entire house I would buy something from Drolet with a 16x16 firebox instead. The stove is very high quality and functions as advertized if you account for all the variables burning wood has.
