The temperature is low, and the solar energy is frozen. Should we fill it with water or empty it at this time?

The temperature is low in winter. If you don't use the solar water heater, you need to empty the water. If you use solar energy normally, you can add water appropriately according to the weather conditions, and it is best to use the water in the water heater several times a day.

1. On sunny days, the solar water heater can be used normally. When the temperature is below -6℃, it is best to use the water in the water heater several times a day. Especially before going to bed and after getting up, put a small amount of water to make the water in the pipeline move, and rely on the water temperature to raise the temperature of the pipeline. The lower the temperature, the more water will be drained to prevent the upper and lower water pipes from freezing.

2. If the temperature is lower than -6℃ the next day, fill the water tank with water after running out of hot water the night before. Loosen the hot water valve slightly and let it drip slowly to keep the water flowing in the pipeline. Generally, the flow rate of a basin of water in one night can prevent the pipeline from being blocked by freezing.

3. Try to use up the water in the solar water heater on cloudy or snowy days, and keep the water mixing valve open all the time to avoid freezing the pipeline.

If you don't use it for a long time, you must empty the water in the water tank to avoid freezing the solar water heater.

Extended data:

Maintenance method of solar water heater in winter;

1. When the temperature is continuously lower than 0℃ in winter, it is necessary to turn on anti-freezing devices such as electric tracing belts for preheating protection. Especially in the cold areas in the north, when the temperature is always below zero, always turn on the heating and anti-freezing devices.

2. When using solar water heater in winter, the water adding time should be determined according to the cold weather.

3. When the weather is cold, the solar water heater without a tropical belt can open the hot water nozzle or faucet, put a basin under it, and loosen the hot water valve slightly to make it drip slowly to keep the water flowing in the pipeline and prevent the pipeline from freezing and cracking.
