I am considering replacing my small insert with a larger insert and looking at potential stoves with a firebox as close to 3.0 cu ft. as possible. The Buck 74 firebox is 2.6 cu. ft. and is under consideration. I see no reviews of the Buck 74 in the ratings so I want to ask any users of the model 74 about your stove. 1) Has the stove met your expectations? 2) On average how many hours of sustainable heat (not burn time) can you obtain from one full load of hardwood before you must reload? 3) If you have a blower installed, have you had any problems with it? Any other comments positive or negative would be most appreciated. Thank you.
