I sold my pellet stove and I am going back to wood. I have a 2200 sq. ft. ranch to heat. I have decided on 3 stoves to choose from. The Lopi Liberty, Harman TL300, of the Jotul F600 Firelight. I am not concerned so much about looks, but want a good burn time and enough heat. I also have a second home in northern Maine that this stove might end up at. That home is appr. 3000 sq. ft. It now has a Hearthstone 2 in it. The home I live in as I said is a ranch style and the chimney is 8" metal, interior, but is only about 12' high, will that be a problem or should I extend it ? Thx
