I am new to the stove market and am looking for advice. The room I want to put my stove in is 576 sq ft. It has 12 foot ceilings and is attached to the main house which is 1800 sq. ft. The opening to the house is about 4 ft wide. I am looking at either the Jotul Castine or the Oslo. Question, do you think the Oslo will be to big? I don't want the family room to be a sauna. At this point, I am not looking for this as a primary heat source, but with oil prices, it maybe some day. Thoughts or other recommendations for stoves?
