Patent ID: 8210132

Claim:
A latent heat recovery-type water heater comprising: a burner that generates a combustion gas; a combustion gas passage in which the combustion gas flows; a first heat exchanger disposed in the combustion gas passage and recovering mainly sensible heat contained in the combustion gas; a second heat exchanger disposed downstream of the first heat exchanger in a flowing direction of the combustion gas and recovering mainly latent heat contained in the combustion gas; and an exhaust portion disposed downstream of the second heat exchanger, the exhaust portion being defined by an upstream face having an inlet of the combustion gas having been flowed through the second heat exchanger and a downstream face opposed to the upstream face and having an outlet of the combustion gas, and the exhaust portion having a deflector disposed in a space formed between the upstream face and the downstream face so as to deflect a flow of the combustion gas having been flowed through the inlet in a direction along the upstream and downstream faces.
