Abstract (en)
A high efficiency heater for air or water is disclosed in which the combustion products from a flame are forced through water in a contacting device (10) in a manner to transfer almost all of the useable heat of the combustion products to the water, and to heat the water to a temperature of about 50 to 85 DEG C. The cooled waste gases are vented to the atmosphere, and the heated water is passed through a heat exchanger (14) to heat air or water such as for a home heating system. As the heated water passed from the contacting device (10) to the heat exchanger (14) is at a temperature below the normal boiling point of water, a plastic heat exchanger can be used, which is low enough in cost to permit using a large unit for maximum heat utilization.
