I am currently considering installing a 70k BTU wood burning insert in my upstairs fireplace, and a 56k BTU wood stove in the basement. The upstairs area is about 1300 sq feet, and the basement is just over 600 sq feet. I was wondering if anyone had an opinion on whether installing both units is worth the extra cost? Would I be better off installing a lager wood stove downstairs and nothing up upstairs for half the cost? Any advice would be greatly appreciated.
