Abstract (en)
[origin: DE10114705A1] Production of a heat exchanger for a condensing boiler comprises preparing a casting mold, equipping the casting mold with cores forming the water and combustion gas surfaces in the heat exchanger, casting the molding, and removing and processing the cast heat exchanger. A specified number of identical cores (1) forming the water surfaces are arranged alternately in a row with identical cores forming the combustion gas surfaces and are cast together in the molding as a monoblock. An Independent claim is also included for a core forming the water surface having a basic plate-shape design. Preferred Features: The number of cores depends on the desired power of the heat exchanger.
