The innovation object is combined condensing heat exchanger that simultaneously serves for pre-heating entering air with combustion plants as also for transferring the temperature of flue-gases to heating medium that enables lowering the temperature of flue-gases at the exit of combustion plant into the chimney. Combined condensing heat exchanger after the invention solves the set technical problem with installation of condensing tube exchanger (3) in the shape of more tubes, installed in parallel, which have in cross-section round or ellipse shape into the flue tube, where in the assembly of condensing heat exchanger after the invention, high-pressure cleaning is enabled with installation of high-pressure cleaning nozzles (7), the exterior housing (4) and fins (4c) on covers (2, 9) enable successful pre-heating of entering air on its way to the fireplace. |
