I recently purchased a small, round Godin 3720 stove. I haven't installed it yet but I will soon. Can any size of these Godin's heat well or are they just pretty? We're going to use ours in an old cabin for ambiance and to take the chill off in the fall. If we were to use the cabin in the winter can these heat an uninsulated room or two. We'll be heating with wood not coal. Anyone know if these Godin's are any harder to operate than any other old, small wood stove? Thanks. - Arnold Z.
