I've been using one in the basement so far this year. I'm the one that was linked to a prior discussion. Here is what I've learned. It works for my case. I have a walk out basement, but I'm not too sure how it works in a fully encased basement. I need to open a window to get going, it will smoke back until I get the draw going, but once I prime it right and have fresh air, removing the negative pressure, it fires right up. I have a rather tall chimney so that at times doesn't help(it's outside block chimney). It can heat my basement up to 80 degrees and it does work is way upstairs through the stairway and floor vents I installed. The mass isn't complete yet so I don't have full efficiency. Winter came early in Michigan. Let me know if you have questions. Also I spent allot of time in my basement, but I wouldn't recommend if you won't be around it for a couple hours. It needs tending to throughout the burn.
