Abstract: A total energy heating unit which provides not only heat but also hot water and electricity is set forth. A single source of fuel is used such as coal, wood, or even compact dry leaves. The fuel is burned in an airtight firebox surrounded on three sides by a hot air containment unit, in which is located a means for generating steam. On top of the firebox is located an enclosure for water circulating tubes. As the fuel burns, it not only furnishes heat for heating air forced through the containment unit and then into a ducting system, but also provides hot air for heating water circulating to a hot water storage tank, and heat for heating a metal block which, when impinged with water droplets, results in generating steam for operation of a steam turbine for the generation of electricity.
