Abstract
The utility model discloses an automatic switching device for a solar water heater and a gas water heater, and belongs to the field of solar energy application. The automatic switching device is automatically controlled according to a temperature of hot water in the solar water heater. When the temperature of hot water is higher than a set value, the solar water heater can directly supply hot water; when the temperature of hot water is smaller than a set value, low-temperature hot water in the solar water heater is taken as inflowing water of the gas water heater and supplied after heated; and when the temperature of hot water just reaches the set temperature, the solar water heater and the gas water heater can simultaneously supply hot water. After the switching device is mounted on the solar water heater and the gas water heater, the consumption of fuel gas can be reduced. According to the device, force acted on a heated expansion member by a compression spring inside a transfer switch is changed by adjusting a switching temperature setting nut in the hot water temperature control electrical transfer switch, so that temperature setting is realized.
