Looking for a small OWB, like the Pro-Fab (mfd.in Canada). Small house, don't need one of the larger behemoths like most folks buy. Any input appreciated.

    gasifier

    I'd consider a gasifier. They burn a lot cleaner and are much more efficient. You need dry wood for most of them. There are several new outdoor models--more all the time as the smoke monsters get banned around the country.

    Blue Forge is one. Adobe and Black Bear Boiler are others. New Horizon has a modified indoor rig that looks pretty cool:

    Greenwood is another gasification unit, http://www.greenwoodfurnace.com/. Depending on your BTU need the profab ECB-200 is a outdoor gasification unit, but may be too big for your application.

    An AquaTherm

    brand can be purchased unsheltered. This allows you to build your own enclosure. AquaTherms are pressurized OWF's.

    The Royall from www.wdheat.com is a small size that could fit in a small enclosure. They sell it as a pressurized or non pressurized vessel. I had one at my home for a bit. Fairly small firebox, however.

    One of the few that has an ASME listing (pressurized version) and UL if your insurance company needs that.

    I'll still sell a Royall

    I prefer the gasification units for efficiency, features and emissions.

    With the small fire box it is sometimes hard to get a full day burn with the small Royall.

    It is a nicely built unit. Heavy steel, nice door, great track record.

    Central boiler had a nice pellet/ corn burner boiler at the FarmFest last week. They build their own feeder and control module in the US. It actually uses a small Lp tank for the ignition system. Fire tube boiler design.

    Central claims they sold 12,500 OWF and boilers last year!
