1. A water heater of a latent heat recovery type capable of heating water by recovering latent heat of combustion gas, said water heater comprising:
a combustion apparatus including a burner that has a plurality of burner port portions and generating combustion gas from openings at ends of said plurality of burner port portions; a heat exchanger heating water flowing through inside by heat exchange with combustion gas generated in said combustion apparatus; and a fan suctioning combustion gas having passed through said heat exchanger and emitting combustion gas to outside of said water heater, said fan including a fan case, an impeller housed within said fan case so as to be rotatable, and a drive source provided outside said fan case and having a rotation shaft connected to said impeller, at least a part of an upper surface of a bottom wall of said fan case being inclined with respect to a reference plane including said openings of said plurality of burner port portions, said fan includes an inlet port through which combustion gas is suctioned, said inlet port is provided at a position in the bottom wall of said fan case that is closest to said heat exchanger in a direction perpendicular to the reference plane including said openings of said plurality of burner port portions, and at least a part of the upper surface of said bottom wall has an inclined portion that is inclined with respect to said reference plane so as to be closer to said heat exchanger as coming closer to said inlet port. |
