Plan on building a rural cabin out of recycled materials & wondered: Has anyone ran a smoker pipe thru a living structure for heat in winter? Granted, you'd need a good shut-out/off vent for when the system is not in use in winter or it is summer, when one would not want the heat, but... say, for a single room - maybe with loft bedroom - has anyone had experience with this? I'd assume, as long as the pipe is tight & insulated against any flammable elements, it might work to heat a dog house or barn, as well. I am quite serious. Thank you, gentlemen, for being kind.
