| A cogeneration system includes a gas engine generator acting as private power generating equipment for generating power to be supplied to private electricity consuming equipment, and a source-side heat exchanger connected to the gas engine generator through an exhaust heat recovery piping to act as a heat source. A heat medium is heated and evaporated through a heat exchange in the source-side heat exchanger. The resulting vapor is allowed to flow upward to be supplied to room heating heat exchangers. The vapor is liquefied through a heat exchange in the room heating heat exchangers. The resulting liquid is allowed to flow downward back to the source-side heat exchanger. This natural circulation of the heat medium is used for the heating purpose. Surplus exhaust heat is released through a generator to control the heat medium supplied to the room heating heat exchangers. Thus, the private power generating equipment supplies power to the private electricity consuming equipment, while exhaust heat of the generating equipment is used to heat rooms. The entire system is constructed at low cost. | ||||||

| Hydrogen Fired Heat Exchanger is an alternative furnace design that utilizes the conversion of hydrogen and oxygen to water to produce heat as opposed to combustion of a fuel like natural gas or oil. The preferred embodiment of the invention utilizes a fuel cell having an anode and a cathode and containing an electrolyte and a catalyst, a water tank, hoses, a gas valve, a spark plug and a heat exchanger. To use Hydrogen Fired Heat Exchanger, an individual connects the water tank to the office or home water line to allow it to fill with water. The fuel cell attached to the water tank provides the electricity necessary to transform the incoming water from the water tank into hydrogen and oxygen gas. A catalyst to expedite the reaction is also utilized in the water. The hydrogen and oxygen gas travel through separate hoses into the gas valve and then into the heat exchanger where the gases are mixed and ignited by the spark plug. The hydrogen and oxygen gas are transformed back into water and emit energy in the form of heat during this combustion process. The heat warms the heat exchanger. The warm heat exchanger functions in a similar fashion to gas heat exchangers. Air from an office or building is sucked through a filter and blowing system past the heat exchanger causing it to warm, and the warm air is then distributed throughout the office or home through a series of ducts and vents. The water created during the combustion of oxygen and hydrogen in the heat exchanger drops to the bottom of the heat exchanger and into the water hose to be returned to the water tank for further use. | ||||||
