Thanks, everyone. Well, at the moment either a Caddy or Jack furnace is still in play. Or, if we do go with a stove, we are still considering the Summit or the Firelight or Oslo. The Summit is still in play as I like the big, unobstructed view of the fire. The Oslo joined the Firelight as I'm a bit put off by the obstruction caused by the double doors on the Firelight and the left hand door on the Oslo would work better for where it is going to go. Also, I'm thinking with the 70,000 BTU's and the 35,000 of the 3450 should be enough. After all, the Morso didn't do a bad job of heating the house by itself. I am concerned if the real burn times of the Oslo will be sufficient I (my Fireview has me really spoiled). I'm curious why Jotul doesn't post their firebox sizes. Does anybody know what they are?
