How to prevent freezing of gas water heaters in winter?

This winter seems to be particularly cold, hot baths are essential every day, and then lying in the warm blanket, don't mention how happy. Going out is really a matter of getting angry. Winter is a rogue, frozen hands and frozen feet. In fact, antifreeze is not just for people to be more careful, but also pay attention to the use of water heaters that contribute to us. Here are a few simple things to note for everyone.

If the user purchases a normal gas water heater, when the outdoor temperature is close to or below 0 °C and encounters windy weather, the water heater must be drained after each use, and the water in the water heater should be drained to prevent damage to the water tank. Water heater. Therefore, the majority of users need to carefully read the product's instruction manual, and strictly follow the relevant requirements of the specification to use gas water heaters.

Especially when the outdoor temperature is below 0 °C, please follow the steps below to prevent the tank from freezing and cracking after each use:

1. Close the inlet valve;

2. Open the hot water valve;

3. Turn the water temperature adjustment knob to the “low temperature” or “big water” position;

4. Remove the safety valve (the safety valve is combined with the thread and the water valve body, and can be removed by left-hand rotation) to confirm that the water is completely drained. When used again, a safety valve must be installed.

While doing antifreeze, do not neglect safety inspection and protection. When no one in the house or long-term non-residence, the inlet valve should be closed and the residual water in the water heater should be vented to prevent the cold air from entering the water heater and causing water leakage, thus damaging the furniture, floor and wall in the home. An anti-downwind device can be installed in advance to prevent cold air from entering the machine to freeze the water tank. When smoke, blockage or backflow occurs in the exhaust pipe, stop using the gas water heater immediately to avoid accidents.
