Abstract

So as to provide a latent heat recovery-type water heater capable of certainly preventing drain generated by heat exchange from being discharged out of an exhaust portion through an outlet with entrained by a flow of combustion gas, an exhaust portionis formed by an exhaust portion constituting-bodyattached above a secondary heat exchanger. The exhaust portionincludes therewithin a deflectorand a distribution boardopposed to the deflector. The deflectorhas a deflection boardextending substantially vertically downward from a top faceof the exhaust portion, so as to form a gapbetween a lower end of the boardand a bottom faceof the exhaust portion. A flowing direction of combustion gas introduced into the exhaust portionthrough an openingof the bottom faceis deflected by passing through the gap, and the combustion gas flows toward the distribution board. The combustion gas hits on the distribution boardto be distributed within the exhaust portion, thereafter being discharged through an exhaust opening
