We're very happy with our Buck Stove Model 91 catalytic insert.
Model 91 Catalytic Wood Stove . It heats our 1800 sqft/full basement home. This will be the 4th winter in use. Features a thermostatic controlled variable speed blower, air wash to help keep the door glass clean, and an ash drawer. Wood loads with the ends facing out, never a danger of rolling out. A bypass door is open until the catalyst chamber reaches about 600 degrees. Once the catalyst "fires", you can damper the fire down to get looong overnight burns. The catalyst helps to maintain a high temperature in the stove, even with a low burn rate in the firebox. Result is little to no deposits in the liner, and longer burn times per load. The manual states that best efficient use of wood doesn't require a visible flame. About the only time I've ever seen smoke from the chimney is when starting a new fire, or reloading. Winters here in Missouri aren't as hard as other places, but we see our share of cold weather. We've yet to be disappointed with our choice of stoves. Mark
