I had this Fawcette hot air wood furnace given to me last summer, I don't realy have room in my garage for it so I decided to make due, and put it outside.
The silver stuff is called Reflectex, it has a class 1-A fire rating so I figured it would be a good barrier to prevent thermal transfer from the siding to the furnace.
First thing I did was to build and insulated base, 2" high R sheathing sandwich'ed betweeen 2 layers of 5/8 plywood, covered by a piece of dura-rok. Keep in mind that most of the stuff I used I had lying around except the steel studs and the reflectex and stove pipe.
my brother had just taken down a tripple wall chimney, 10" inside and 15" outsied, I made some pieces to cover the ends and filled in between with vermiculite for insulation, these are my hot/cold air lines to the garage.
my brother also had this piece of ductwork,
I've had this blower for years, not knowing what I needed it for..lol
