Abstract
A water heater includes a burner generating combustion gas, a heat exchanger heating water which flows through the inside, through heat exchange with combustion gas generated in the burner, a fan supplying air to the burner, and a housing storing these components. The water heater has a water entry portion in a top plate of the housing. A water supply pipe for supplying water to the inside of the heat exchanger is connected to the water entry portion. The water entry portion is arranged to be included, in a plane view, in at least one component constituting the heat exchanger and an exhaust path for combustion gas which has passed through the heat exchanger. The component is made of a material having corrosion resistance against drainage water resulting from condensation of combustion gas.

A water heater, comprising:
- a burner generating combustion gas;
- a heat exchanger heating water which flows through inside, through heat exchange with combustion gas generated in the burner;
- a fan supplying air to the burner;
- and
- a housing storing the burner, the heat exchanger, and the fan,
- the water heater having a water entry portion in a top plate of the housing, a water supply pipe for supplying water to inside of the heat exchanger being connected to the water entry portion,
- the water entry portion being arranged to be included, in a plane view, in at least one component constituting the heat exchanger and an exhaust path for combustion gas which has passed through the heat exchanger, and
- the component being made of a material having corrosion resistance against drainage water resulting from condensation of combustion gas, wherein
- a temperature of a part of the component, on which condensate generated in the water entry portion drops, is a temperature at which noise generation at the time of evaporation of the condensate is suppressed.
