Solar energy freezes in winter. The solutions are: wait for natural thaw and heat the pipes.
1. Wait for natural thaw
If the solar is frozen in winter but has not been physically damaged, you can wait for natural thaw. Typically, solar power is designed to withstand cold and freezing temperatures and will thaw naturally if the weather warms. But this method may not be effective enough if the weather is chronically cold or if the solar energy has been physically damaged.
2. Heating Pipes
Generally, solar will have an electric heating tape on the hot water pipe. If the water pipe is frozen, use the electric heat tape to energize it. a few minutes and the frozen ice cream will melt by itself. If there is no electric heating tape installed, you can turn off the outlet faucet, dip a towel inhot water and apply it to the water line, then drain the water once the ice melts. If the water inlet pipe is not blocked, you can also heat the water to melt the ice.
Precautions for using solar energy in winter
1 If it rains and snows continuously in winter, try not to add any water to the solar system. If the water inside is relatively full, you can try emptying some of it to prevent the water tank from freezing and damaging it.
2. If you encounter snowy weather, the snow on the solar vacuum tube should be removed in time. Snow cover will affect the exposure of sunlight to the vacuum tube and affect heat absorption. It must be removed in time, let alone wait for the snow to thicken, freeze and freeze the vacuum tube.
3. In winter, a full inspection should be carried out to check if the pipes are disconnected, leakingnt, cracked, etc., and at the same time, good quality insulation materials or anti-freeze devices should be carried out. used to protect themselves. Open the electric heating tape in advance for antifreeze to avoid severe freezing of the pipes. Do not turn the electric heating tape on and off frequently to save energy, which will cause the current in the electric heating tape to increase and cause damage. the electric heating tape.
Solar energy is frozen, how to thaw it?
The ways to quickly thaw a frozen solar water heater are to pay attention to the timing of water filling, ventilation antifreeze method, dripping antifreeze method , etc.
1. Pay attention to the time when the water supply is selected.
When using solar water heaters in winter, the water filling time should be determined based onwe weather conditions. . If the temperature outside is above freezing, you may consider adding water that night. If the outside temperature is below freezing, it is best to add water the next morning to prevent the water outlet from freezing.
2. Ventilation and antifreeze method
If the temperature is too low in winter or the solar water heater is not used for a long time, it is necessary to turn off the water. water heater supply valve and drain the water in the upper and lower pipes of the water heater, to prevent freezing and cracking of water pipes caused by low temperatures and lack of water circulation .
3. Drip antifreeze method
For solar water heaters without antifreeze heating tapes, you can only choose to use the traditional drip antifreeze method if the weather is cold, you can turn. on the water sprinkler chot or waterPlace a basin under the tap, loosen the hot water tap a little, turn it to minimum and let the water flow drop by drop, in order to avoid freezing and cracking of the water pipes . If it is an electric water heater, it is best to drain the water inside.
Daily maintenance of solar water heaters
1. When installing the solar water heater, there may be dust or oil smell in the water pipe. open the tap when using it for the first time. Remove debris first.
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keep the sClean water heater surface can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It should be removed and cleaned regularly to increase water flow. smooth the water.
1. Solar water heaters will have electrical tapes on the hot water lines. If the water lines are frozen, use electrical tape to power them for a few minutes and the ice will relieve itself.
2. Wrap the water pipe thickly. This can play a certain antifreeze role.
3. Thaw slowly with hot water. This method takes time. After melting the ice, you need to drain the water when not in use. This way it won't freeze easily.
4. Wait for the temperature to rise and the solar energy to thaw on its own.

Preventive measures to avoid freezing of solar energy:
1. Flowing water is not easy to freeze. This principle can be used to prevent solar pipes from freezing and blocking. On sunny days with low temperatures, fill the water heater with water and use it several times a day. Allow the hot water from the water heater to flush the cooling water from the pipes to prevent freezing.
2. To prevent pipes from freezing, drain the water from the water heater during cold winters and on sunny days when the temperaturetemperature is less than minus 5 degrees. This is the most effective and comprehensive antifreeze measure. .
3. When the temperature drops below freezing, turn on the heat tape to insulate the pipes to prevent freezing.
