The gas water heater is a common household appliance, and when the ambient temperature is very low, a water tank of the gas water heater can be frozen and cracked without anti-freezing measures, so that water leakage of the water tank is caused. The following two types of freeze protection measures are often adopted in the industry for such problems: firstly, increase electric heating freeze-proof device on the water tank, secondly machinery is frostproofing, increases the drain valve in water tank water inlet department, directly emptys the inside water of water tank, prevents the water tank frost crack. At present, gas water heaters in the market are generally provided with drain valves for mechanical freeze prevention, and electric heating freeze prevention devices are added to partial products.
The mechanical anti-freezing of the drain valve is only suitable for the anti-freezing of the water heater under the condition that the water heater is not frequently used, if the water heater is frequently used, the drain valve is required to be detached during anti-freezing, and the drain valve is required to be installed during use, so that the water heater is quite inconvenient.
For the gas water heater added with the electric heating anti-freezing device, the heating power is limited, only local heating can be realized, water close to a heat source is heated firstly and then is gradually conducted to other positions, when the outside is very cold and outside cold air enters the water heater, the anti-freezing device possibly does not heat one part of water, and the water tank of the water heater is frozen and cracked.
