I will be purchasing one of these stoves to heat my 1200 sq ft home in mid-coast Maine. The house is old and loose. I previously had a Waterford Leprechaun. The main room where the stove will sit is a addition built to the side of the house and is about 200 sq ft. I have forced hot air but want to heat mostly with wood. Do you think the smaller 13 would work or should I go with the 30. I just don't want to be blasted out of the living room. Thanks for any help!
