Hello! We are building a new home and want a woodburning fireplace as a heat source opposed to a standard fireplace. Our builder has presented the QuadraFire Pioneer III as a woodburning option. I am thinking this may be a bit big as upstairs will be 1830 sq. ft., and also was wondering if this is operable (and safe to operate) in the case of a power outage rendering the fan & t'stat unusable. Can anyone help? Thank you!
