Condensing heat exchanger and water heating/heating device

Abstract

The disclosure discloses a condensing heat exchanger and a water heating/heating device thereof. The condensing heat exchanger includes: a housing including a first end portion and a second end portion opposite to each other, and a side wall arranged between the first end portion and the second end portion, the second end portion being provided with a mounting portion for mounting a combustor; a smoke outlet arranged on the housing; a heat exchange component arranged inside the housing; and a first heat insulating member arranged close to the first end portion. A first gap is provided between the first heat insulating member and the first end portion, and at least part of smoke which has exchanged heat with the heat exchange component can flow through the first gap and be discharged from the smoke outlet. This application improves reliability of the condensing heat exchanger and the water heating/heating device thereof and reduces the cost by optimizing an internal structure of the condensing heat exchanger on the premise of ensuring the heat insulating and cooling effect.
