When the weather is cold, how should the gas water heater operate the water in the emptying machine?

1. Close the water inlet valve of the tap water pipe, screw one end of the drain pipe to the pressure relief hole of the safety valve, and open the safety handle.

2. Open the hot water valve to the maximum, and water will be discharged from the pressure relief hole and nozzle hose of the safety valve.

3. Before reuse, turn on the hot water valve, and then turn on the power switch of the water heater.

4. In this way, the gas that may exist in the pipeline can be discharged from the pipeline.

Extended data:

Maintenance of gas water heater when the weather turns cold;

First, prevent air leakage.

1. When the weather turns from hot to cold, the joint between the gas valve and the hose is prone to crack when it expands with heat and contracts with cold, and there is a risk of gas leakage.

In order to ensure the safety of use, users can evenly smear soapy water on the hose connector and its pipeline after foaming, observe whether there are bubbles and judge whether there is air leakage. If there is air leakage, they should immediately close the gas valve, open the window for ventilation, and contact professional maintenance personnel for home maintenance.

2. After using the gas water heater every time, it is recommended to close the gas valve to avoid carbon monoxide leakage. Also regularly check whether the gas supply pipeline is intact, aging and cracked.

Second, the correct antifreeze

Under the influence of low temperature weather, the water tank, fittings and water pipes of gas water heaters are easy to freeze and crack, resulting in water leakage, thus damaging furniture, floors and walls at home.

Therefore, in order to prevent the gas water heater from freezing, we should do proper anti-freezing treatment in winter. For the non-freezing gas water heater, when the outdoor temperature is close to or lower than 0℃, the water heater should be drained after each use, and the accumulated water in the machine and pipeline should be discharged to avoid freezing and cracking the pipeline and damaging the water heater.

For water heaters with anti-freezing function, check whether the machine is powered on and ensure that the anti-freezing mode is in working condition.

For areas where the temperature is often below 0℃, it is recommended that you buy antifreeze gas water heaters.

Third, regular cleaning.

The gas water heater installed in the kitchen will accumulate oil stains on the surface of the machine due to long-term contact with lampblack. If it is not cleaned in time, the buttons of the water heater may fail.

Therefore, it is very necessary to clean and maintain the outside of the water heater regularly. When cleaning the outside, wipe it with a wet towel, but be careful not to use acidic and alkaline cleaning agents; Pipeline cleaning needs to close the main natural gas valve first, and then wipe it with cold water and wet towel.

Compared with external cleaning, internal cleaning of gas water heater needs to disassemble the water heater, and users are not recommended to disassemble and clean it themselves. You can contact professional after-sales service personnel to handle it at home.

Fourth, check the discharge frequency.

For the inspection of discharge frequency, it can generally be determined according to the low-voltage indicator light on the water heater. When the water heater is running, the red light is on, indicating that the battery needs to be replaced.

If there is no low-voltage indicator light on the water heater, it can also be checked according to the sound frequency generated by discharge during use. If the sound frequency is slow, it means that the discharge frequency is low, and then the battery needs to be replaced.
