How to solve the problem of solar energy freezing in winter

1, scientific use of heating anti-freezing device.

Usually, solar water heaters are equipped with heating and anti-freezing devices, and users often use them to thaw after the pipes freeze, which not only delays the use, but also harms the life of solar water heaters.

The scientific method is to pay attention to the weather forecast, and when the temperature is kept below 0℃, turn on the anti-freezing device for preheating protection. Don't worry about power consumption, because the power of electric heating belt decreases with the increase of temperature in use, and the power consumption is very small. However, attention should be paid to unplugging the plug and cutting off the power supply when taking a bath to prevent accidents caused by out-of-control heat balance.

2. According to the weather.

Listen to the weather forecast in time. When the temperature is not low (5-7℃), after using water that night, if there is hot water in the water tank, immediately fill the solar water heater with water to reduce the water temperature in the water tank and the heat loss that night. If the temperature is low, water should be supplied the next morning to help prevent the pipeline at the outlet of the water heater from freezing.

If it is rainy and snowy the next day, half a box of water or half a box of water can be used according to actual needs; If the water consumption is large, you can consider turning on the electric heating device in the solar water heater.

3. Turn on the hot water tap and drip water to prevent freezing.

If the solar water heater is not used for a long time in winter, the water supply valve should be closed, and the water in the water heater and the upper and lower pipes should be drained to prevent the pipes from freezing. On sunny days, solar water heaters can be used normally; When the temperature is below -5℃, it is best to use the water in the water heater several times a day. Before going to bed, you can connect a basin under the shower head or faucet, so that the hot water valve can drip slowly, keeping the water flow in the solar water heater smooth and effectively avoiding the pipeline from freezing.

Matters needing attention in using and maintaining solar energy in winter:

1, when using solar electric heating, special attention should be paid to the amount of water, so that the amount of water in the water tank is not less than 50% to prevent dry burning without water. Be sure to cut off the electric heating power supply when taking a bath.

2. The use environment and user habits have great influence on the service life of solar energy. Even in severe winter, the water tank must not be replenished immediately after drying in anhydrous air to prevent explosion. The best water supply time is 2 hours before sunrise or after sunset in the morning, especially when there is no light.

3. In windy weather, please fill the water with solar energy to increase the wind resistance and load-bearing capacity of the water heater, and disconnect the power supplies such as electric heating and meters; It is forbidden to use solar energy in thunderstorm weather to ensure personal safety.
