Abstract: A heat exchanger management system and a method of operating the heat exchanger management system. In one embodiment, the heat exchanger management system includes a memory and an electronic processor electrically connected to the memory and configured to operate one or more burners to transmit heat to a heat exchanger for a first period of time that deposits corrosive condensates on a passivation layer of the heat exchanger, deactivate the one or more burners for a second period of time, operate one or more blowers to move air across the heat exchanger at a temperature that evaporates the corrosive condensates on the passivation layer of the heat exchanger and increases an oxide thickness of the passivation layer on the heat exchanger, and reactivate the one or more burners after the second period of time.

Abstract: A heat exchanger for a heating device, especially a fuel value heating device, made up of at least two vertically aligned members, and, in each case, one cover at the end face, which form a combustion chamber, and laterally border at least one heating gas flue, that leads from the combustion chamber in the upper region downwards to an exhaust collector in the lower region, having heat exchanger surfaces which, on the heating gas side, are provided with elements that increase the size of surfaces, especially in the form of ribs, optionally having at least one middle member between the two bordering outer members, and having a plurality of channels guiding the heating medium flowing through in parallel and/or in series in the members and/or the covers. The present system provides a compact heat exchanger for a heating device, and which is light and is especially suitable for the fuel value operation.
