It looks like there is plenty of opportunity for good heat circulation there. How high is the ceiling in the living room and is there a ceiling fan? With a little fan assist it looks like there would be a good shot at heating most of the 1st floor. Based on what I see here I would not go under 2 cu ft or you may be buying a larger stove next year. (Don't ask how I know this.) I'm glad you got a chance to look at the Shelburne. Did you also look at the Manchester?
