according to nfpa i can't install a woodstove in my shop. so i was thinking about building a doghouse for my woodstove outside and using an air to air heat exchanger to blow the hot air into the garage.
I've seen one in person, it was outside out behind an attached garage in a stockaded area with a wood pile, trash cans and whatnot, looked like it was working out pretty well.
Of course there are others that may seem a little hinky.

I have seen two installations like this. Both were wood furnaces designed for central warm air systems.
One was specifically made for outdoor installations, and had insulated ducting installed above ground.
The other was a little closer to the green van pictured above, in that it was installed in an uninsulated metal shed, sat on the dirt, was immediately adjacent to an old trailer, and just had some crummy ductwork cobbled up to blow the heated air into the side of the trailer - not professional at all.
