Hey everyone. My father in law is looking for a new wood stove to replace a small inefficient one he has had for about 20 yrs. He has an insert at one end of the house and uses this one for at the opposite end for supplemental heat when it gets really cold. He asked me to look around for him so I thought I would ask here for suggestions. He wants something with no glass doors and more efficient than his old model. It doesn't need to be a big model probably small to medium size. Any thoughts?
