Abstract: A stove bench comprised of a metal liner forming an interior duct which is covered with tiles or masonry to form the outer face of the stove bench, an inlet to the duct for receiving hot exhaust gases from a stove or furnace, and an outlet from the duct for the exhaust of the gases to a chimney or the like. The bench has a top that is also covered with tiles, masonry, or soapstone, permitting heat conduction thereto, and permitting the top to serve as a seating or sleeping surface. The stove bench is preferably supported on two legs and has a clean-out door, preferably disposed at one end of the stove bench. A damper is disposed at the outlet from the structure for controlling the gases passed through the stove bench.In an alternate embodiment of the stove bench there is further included an insulated bypass duct disposed beneath the first, heat-conducting duct.
