This seems like a great little insert but I can't find any reviews or information on it. My local stove outlet doesn't keep one in stock and it would have to be special ordered. Anyone have one that can share some insight? Is it big enough to heat a 600 sq ft room? House is 2000 sq ft rancher. I have supplemental gas heat and really just want to heat my living room at night after work and on weekends. With such a small firebox (1.2 cu ft) I figure I can get away with much less wood. An alternative seems to be the 33 Elite (2.2 cu ft) but don't want a big box if I don't need it. Thanks for any insight and help.
