Abstract
The utility model provides a two-level freeze-proof gas water heater. The two-level freeze-proof gas water heater comprises an outer shell, a heat exchanger tank body, a water pipe, a heating body, a temperature controller, a temperature sensor, an alarm module, and a central controlling module, wherein the heat exchanger tank body is arranged inside the outer shell, the water pipe is connected with the tank body, and the heating body is used for heating water inside the tank body and/or the water pipe. Besides, the temperature controller is in electric connection with the heating body and is used for controlling heating of the heating body when a detected temperature is lower than a first freeze-proof temperature. The central controlling module is in electric connection with the temperature sensor and the alarm module.
