I was wondering if you could give me the name of a company or dealer that sells the outside fireplace stoves that you connect to the ductwork of your house. These fireplaces are freestanding outside your house and you load them up with wood or coal to heat up the air in the sealed space around the stove, which is in turn forced out of the vents in your house through the ductwork. I know these types of stoves exist, as I've seen homemade versions of them, but I would like to know if anyone manufactures this kind of stove. I haven't been able to find a company that does make them, so I thought you might.
