Well I finally pulled the trigger on my first BK, a 2 year old Princess with a new factory cat that I found online for $1700. I'm coming from a small pleasant hearth home depot non-EPA stove that was rated to 1500sqft with a top and bottom damper. My house is 1900 sq ft and was built as a heat pump house in 1987 so it's pretty well insulated (still use the heat pump above freezing). Its setup with 3 floors like a split level and the stove is on the bottom floor in a corner with 3, 8"x12" through vents going to the top floor bedroom, spare room and hallway. The little stove was able to keep the house between 68-72 but even an 8 hour burn was a STRETCH with both dampers closed. Really looking forward to the longer burn times, being able to load wood N/S and the steady heat from the T-stat. Cant wait to get it fired up.
