How to use solar energy normally in winter

First, it is necessary to use heating and anti-freezing devices scientifically. Generally, solar water heaters are equipped with heating and anti-freezing devices. Consumers often use them to thaw pipes when they freeze, which not only delays the use, but also damages 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.

The second is to supply water according to the weather conditions. 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.

The third is to 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.

Especially before going to bed, you can connect a water basin under the nozzle or faucet, loosen the hot water valve slightly and let it drip slowly, so as to keep the water flow in the solar water heater smooth and effectively avoid the pipeline from freezing.
