Some friends have one. They call it a Russian Stove. They live at 10,000 ft altitude in Colo on the North side of the slope. I kinda like it, but as others have noted, these stoves need to be built during initial construction to avoid some real remodeling headaches. Sometimes the back door to the house is left open during the day, and they don't have to stoke the thing frequently, like I did with a steel stove.
