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.

Abstract: A heating system for heating a confined area with an open-hearth wood-burning fireplace. A fireplace jacket is provided which comprises a multi-chambered double-walled arrangement or a grate member. Log supporting portions of the jacket slant upward slightly in order to prevent a pinging sound by creating convectional force when water is circulating therethrough. The grate member includes first and second headers formed from prisms with triangular bases, and water conducting pipe portions extending on three sides of a fire burning in the open-hearth fireplace. The fireplace jacket is readily utilizable with a conventional forced-air furnace in association with a heat exchanger disposed in the furnace cold air return. Combustion air for the fire is provided from an area external of the confined area to be heated by the heating system.

Abstract: A simplified method for the fabrication of a fireplace water jacket, and the water jacket produced by the fabrication method. Each of several walls of a water jacket is formed from first and second metal plates. The first metal plate of each wall is disposed in a generally horizontal position on an orificed support, and a punch is brought into operative engagement therewith to punch a hole in the plate and simultaneously deform the area surrounding the hole so that the plane of the hole is spaced a given distance as from the plane of the plate. The first plate is then placed on the second plate so that the plates are generally parallel and so that the area surrounding the hole in the first plate abuts the second plate, and then the plates are secured together by welding around the area defining the hole in the first plate to the portion of the second plate visible through the hole in the first plate. The plates when joined together are spaced apart a distance S and water may circulate between the plates.

Abstract: A fireplace jacket assembly and heating system associated therewith. A fireplace jacket assembly including water chambers on five sides of an open wood-burning fireplace having means for providing water communication and circulation therebetween is placed in a conventional heating or hot water system. A pump circulates the water between the component parts of the system including a water storage tank and a radiator, and means are provided responsive to the temperature of water within the storage tank for preventing heating thereof by conventional (i.e., fossil fuel or electricity) means, or by a solar heating system. An opening formed in the bottom of the fireplace jacket provides for greater efficiency.
