Invention increases boiler efficiency - The EnergyCatcher recycles the heat in a domestic gas boiler’s exhaust fumes and uses it to preheat and store hot water for use in the home. Said to reduce fuel usage by at least 5%. (Green Building Mar. 10, 2008)

Heat exchangers of multiple cylinder internal combustion engine There was an error working with the wiki: Code[1] April 6, 2006 {666}
Summary : The present invention relates to a heat exchanger for carrying out heat exchange between a heat medium and an exhaust gas from a multicylinder internal combustion engine.
Abstract : First heat exchangers (H4, H3, H2) are disposed within an exhaust port (18), within a pre-catalytic device (34), and on the downstream of a main catalytic device (35) the exhaust port (18), the pre-catalytic device (34), and the main catalytic device (35) being provided in each exhaust passage (33) of a multicylinder internal combustion engine. These first heat exchangers (H4, H3, H2) are independently provided for each of the exhaust passages (33), and a second heat exchanger (H1) is disposed in a section where these exhaust passages (33) are combined. Since the first heat exchangers (H4, H3, H2) are disposed on the upstream side of the exhaust passage (33), high heat exchange efficiency can be obtained by high temperature exhaust gas, and, moreover, the occurrence of exhaust interference can be avoided, thereby preventing any decrease in the output of the internal combustion engine.
