Claims

[Scope of utility model registration request]

A water flow sensor is installed in the flow path leading to the heat exchanger, and when the flow sensor detects the flow of water, the gas valve that supplies the burner is opened and the gas in the burner is ignited to heat the heat exchanger. In the container, a first flow path leading from the water supply flow path to the hot water outlet via the water flow sensor and the heat exchanger, and a first flow path leading from the water supply flow path to the hot water outlet without passing through the flow water sensor and the heat exchanger. A branch part where the water supply flow path branches into the first flow path and the second flow path is provided with a stop of water supplied from the water supply flow path and a second flow path leading from the water supply flow path. A stop-off type water heater is provided with a switching valve that selectively switches water between a first flow path and a second flow path.
