Just bought the 2200 sq ft stove from lowes. It is a really nice stove. I have it in my basement living room which is about 300 sq. ft.. I let the stove run on high all night long. The highest the temp got in the room (opposite side coffee table) was around 67 degrees f. I would think that a 50,000 btu stove would run me out of the room. Fire has a good burn to it so i'm not sure if its the stove itself (using high grade pellets). Stove gets plenty hot but the air temp coming out of the stove feels around 75-80 degrees. I have a 30,000 btu natural gas ventless wall heater that will heat the room no problem. Any thoughts?
