It can be damaged by frost. When the temperature is below minus 8 degrees in winter, it will freeze and crack. Solar tubes damaged by frost will permanently break and need to be replaced with new ones.
Particular attention should be paid to the antifreeze of solar water heater pipes, especially the connection between the water tank and the water pipe. This place is easy to shake when the wind is strong. If the connection is not good, the water pipe will be easily exposed. If there is no drainage of the solar water heater, it is easy to freeze and block, preventing hot water from coming out and cold water from coming out.
Therefore, water pipe insulation work must be carried out well. Generally, the length of an insulation pipe is two meters. The joints of each insulation pipe should be tightened with tape to prevent them from becoming disconnected. qhen the wind is strong or the water is flowing.
Generally, solar water heaters are equipped with anti-freeze heating devices. Many users often use it to defrost the pipes after they are frozen, which damages the lifespan of the solar water heater. The correct usage method is that when the temperature remains below 0°C, the antifreeze device should be turned on to carry out preheating protection. If the temperature is relatively low only at night in winter, the antifreeze device can be activated at night and turned off during the day.
Detailed information
Methods to prevent pipes from freezing
1. If the temperature is not very low, after using hot water, Night, refill the water immediately to reduce heat loss that night and make full use of thermal energy.
2. If the temperature is relatively low, get into the water after you haveeve the next day. And put a small amount of water before bed or the next morning to prevent pipes from freezing and clogging.
3. If the sunlight is not strong that day and it is raining or snowing, you can fill half a tank of water or more than half of a tank of water as needed real.
4. If the water consumption is large, you can consider starting the electric heating of the solar water heater or putting the water from the solar water heater into the electric water heater to heat it slightly.
5. When the temperature is below 0℃, be sure to turn on the antifreeze device. After mastering these tips, you will be able to use your solar water heater well in winter.

What should I do if the solar water heater freezing?
1. Electric Heat Tape: Typically, water heatersSolar panels have electric heating tapes on the hot water pipes. 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: If there is no other method, you can try wrapping the water pipe yourself. This can play a certain antifreeze role.
3. Defrost with hot water: You can use hot water to thaw slowly. This method takes a lot of time. After the ice melts, the water in the solar panel should be drained when not in use, so that it will not freeze easily.
What to do if the solar water heater freezes and no longer produces water
Once the solar water heater freezes, the problem can be solved with the solar defrost function.
This means keeping the water heater warm, melting ice and defrosting. This is usedin winter. Click this button to.To activate the antifreeze belt to prevent the upper and lower water pipes from freezing and clogging. This means installing heating tape on the solar water supply and drainage pipelines, and using the heating tape to heat the pipeline to keep the pipeline at about 10 degrees, which not only prevents the pipeline from freezing and block, but also thaws the frozen pipeline. .
Detailed information:
1. Antifreeze by running water
As long as the water continues to flow, the risk of freezing is very low. Before going to bed at night, you can turn on the hot water faucet slightly and drip it slowly to ensure that the water flows through the water pipes. Remember to put a bucket to collect the water so you can use it the next day.Don't waste water.
2. Drain and prevent freezing
When the temperature is extremely low or when solar energy is not used for a long time, the original water from the solar water heater should be recovered. in a bucket and drained. This way there is no water in the water pipe and it will naturally not freeze.
3. Anti-freeze heating tape
Solar water heaters installed in the north all have electric heating tapes When the temperature is below freezing, remember to turn on the electric heating tapes. , which can effectively protect solar water heaters from freezing.

1. If the weather continues to be low, try not to fill the water heater at night, aslow temperature at night can easily lead to freezing if there is water. can turn on the water heater at night. Open it to the minimum, but make sure the water drips out overnight to prevent freezing water pipes.
2. For solar water heaters that have been frozen, we should not forcibly flush the solar vacuum tubes with hot water. It is best to wait until the next afternoon when the sun rises. is the strongest. Let it melt naturally after being exposed to the sun. Try not to rinse the solar vacuum tube with hot water, otherwise it may damage the vacuum tube.
3. Antifreeze equipment can be installed Nowadays, solar thermal conductive medium is also called solar antifreeze, which is mainly used for flat solar water heaters, mainly domestics. vacuum tubes. Since the thermal efficiency of heatersFlat panel solar water heaters can reach more than 76% in terms of energy utilization, which is much better than that of vacuum tube water heaters, flat panel solar water heaters also began to be widely used in China, which can effectively prevent solar energy from freezing.
