Water and room heater

An improved water heater and room heater for more efficiently utilizing the combustion heat of cumbustible materials and the like comprising a firebox having a top and a bottom, said firebox including a first metal water chamber, a second metal water chamber, and a third metal water chamber arranged to form U-shaped, vertical walls, said first water chamber, said second water chamber and said third water chamber each having a plurality of solid, metal, elongated, vertically spaced ribs projecting therefrom and into the firebox for thereby transmitting the heat from the combustion of materials in the firebox to the water located in said first water chamber, said second water chamber and said third water chamber;

• a plurality of metal grates for supporting the combustible material, said plurality of metal grates connecting said first water chamber to said second water chamber, said plurality of grates providing a first network for passage of water from said first water chamber to said second water chamber, and for extracting heat from the combustion of materials in said firebox;
• a plurality of heat extracting members located at the top of the firebox, said heat extracting members including a plurality of metal heat extracting pipes having a plurality of radial projecting fins located thereon, said radial fins alternately spaced on said metal heat extracting pipes, said plurality of heat extracting pipes thereby providing a second network for passage of water between said first water chamber and said second water chamber, said plurality of radial projecting fins coacting with said heat extracting pipes to more efficiently extract heat from the combustion of materials in said firebox;
• said first water chamber, said second water chamber, said third water chamber, said network of grates and said network of heat extracting pipes thereby coacting to provide a firebox that is operable for receiving the heat of combustion from the combustible material from at least five different sides, a cold water inlet located at the bottom of said water chamber and a hot water outlet located at the top of said water chamber, said firebox further including means for receiving the combustion ash, means for allowing the entrance of combustion air, means for controlling the amount of combustion air to the firebox chamber, and means for discharging the combusted gases.
