How does the heat physically get into the duct system? Or does the stove just radiate heat up from the basement through the flooring? My sub-flooring is actually insulated. I would have to put a woodstove in the basement where the propane burning furnace is along with the ductwork. I have only 2 small basement windows about maybe 18 inches wide by maybe 10 inches high. Can the piping get out through that? Would I have to add a chimney also? It would have to go up 2 stories.
You could get a wood furnace for the basement, or you could get a woodstove to put on the living floor and let it radiate.
