i've read on other websites about owb being so uneffiecent ,waste of wood ,more work,have to go out in the cold,by yahoos with there woodstoves. they think they get the same output as a owf . if being uneffiecent is 72 deg in house when its 8 deg outside ,burning junk wood like pine ,nasty hardwood crotchs that cant be split. then yes. i burned woodstoves in both of my homes and i dont remember it being that warm , maybe in one room and the other rooms 10 deg cooler, and to say you have to go out in cold , i dont remember stocking a seasons worth of wood in my house so i didnt have to go out in the cold either. i dont miss lugging wood in the house .cleaning ashes and wood bark up . with 2 woodstoves going it would take hours to get house up to temp after it dropped over night. knowing what i know now i would have done this years ago.
