Abstract

A wood or coal burning stove having walls defining a fire chamber with a flue disposed in one of the walls. A door provides access to the fire chamber, and a vent for controlling the combustion air is provided in the door. A manifold connected to inlet and outlet pipes passing through the walls provides for circulation of water through the fire chamber to heat the water with a fire burning in the fire chamber. Fuel supporting members extend downwardly from the manifold to support the fuel below the manifold, a number of generally U-shaped pipes with both ends of each pipe in fluid communication with the manifold providing the fuel supporting members. A baffle or like structure is provided in the manifold for preventing short-circuiting between the inlet and outlet pipes, and the manifold is supported in a generally horizontal plane. A damper is movable between a start-up position wherein gases may flow directly from the fire through the flue, to a normal position wherein gases are forced to flow both past the bottom and top of the manifold before exiting the flue.
