Some people don't need, nor do they want a wood fired furnace. I personally would rather have the nice glow of a fire in my living room, than have to find, cut, haul, split, stack, then carry into my home to not be able to enjoy the fruits of my labor (and free time) by not being able to enjoy the fire and the radiant heat warming my entire house, not just the air.
Wood furnaces, as well as OWB's just don't fit everyone's application or needs, for some (me included) a wood stove was the only way to go. I bought a Vogelzang stove, and am completely satisfied with it's looks, form, fit, finish and most of all it's performance.
