With the temperature turning cold, many areas in the north have gradually snowfall, this time

The gas water heater used in the application is easy to lock and can not be used normally, and even cause the electric water heater storage tank to be frozen.

Therefore, by this time, we must carry out cold maintenance on gas water heaters to prevent the normal application of boiling water. So, how can gas water heaters prevent cold?

In winter, the room temperature is above 0 degrees, why should the drainage pipe be cold?

Although the gas water heater is installed in the room, the exhaust pipe of the organic exhaust gas is direct to the outdoor gas. When the equipment is terminated, the strong cold air outdoors will enter the inside of the equipment according to the exhaust pipe. The residual water in the gas water heater freezes and causes the copper tube of the air conditioner inside the electric water heater to expand and crack.

First, look at your own installation of the natural environment, see if the temperature will be less than 0 ° C, especially installed on the balcony, and long-term no one to settle the house, be sure to pay attention to the cold process of the electric water heater.

Cold protection process of gas water heater in room

1, pull out the power plug, power off;

2, turn off the electric water heater gas valve;

3, turn off the electric water heater water valve;

4, open the water mixing valve boiling water end;

5. Twist the pressure relief screw of the inlet valve to develop the drainage pipe;

6. After the drainage pipe is over, tighten the pressure relief screws again and turn off all the inlet and outlet valves, and test the pressure again

Naturally, in order to better prevent the inconvenience, you can also buy a gas water heater containing the cold effect, when the operating temperature is less than 5 ° C, the electric heater equipment in the gas water heater containing the cold effect will run heating, to ensure that the temperature in the gas water heater is not easy to be less than 0 ° C. When the temperature is higher than 10℃, the electric heater equipment will be automatically turned off. However, it should be remembered that automatic cold protection equipment can only be fully utilized when the gas water heater is maintained plugged in, so do not turn off the power when the electric water heater containing cold protection is cold in winter.
