Solar antifreeze methods:
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 zero, remember to turn on the electric heating tapess. , which can effectively protect solar water heaters from freezing.

Precautions for using solar water heaters:
1. The water stored in the solar water heater should be drained regularly to avoid pollution caused by long-term water accumulation. The discharge cycle is determined by local water quality conditions. The rejection can be carried out in the morning because the sensor temperature is lower there.
2. If the weather is good for several consecutive days without using hot water, the water temperature will be relatively high. When using it, you should turn on the cold water first, then the hot water to avoid scalding.
3. Solar water heater pipes are often frozen in winter. If there are no cracks in the frozen pipes, there is no cause for concern. They will be able to function normallyalso when the temperature increases.
4. If you need to thaw a frozen pipe, do not hit it, grill it over a fire, or use boiling water, otherwise the pipe may burst. You can use a towel to wrap the pipe, then slowly pour warm water or blow with a hair dryer to treat the pipe.
5. To prevent scale from forming inside the vacuum tube of the solar water heater, it must be cleaned regularly, every 2 to 3 years.
6. For solar water heaters equipped with special instruments, pay attention to electricity and lightning protection, and be sure to unplug the plug of the electric heater when using it in a thunderstorm.
7. When using a solar water heater for the first time, you can turn on the faucet to drain the water so that any debris that may be stuck in the water line can be flushed outbefore use.

How to prevent solar water heaters from freezing in winter?
1. Use anti-freeze devices for heating
Some solar water heaters are equipped with anti-freeze devices, as long as they are used promptly and reasonably, they can effectively prevent pipelines. frost and crack When the temperature continues to be below 0 When the temperature reaches ℃, the antifreeze device should be turned on in advance to carry out preheating protection.
2. Pipe insulation and antifreeze
Solar water heaterIf there is no antifreeze device and the temperature is too low, the pipes will freeze and crack easily. In winter, it is best to insulate exposed pipes. You can use insulating materials such as cotton or softplastic to wrap the exterior. pipes.
3. Choose the correct time to add water
Determine the time and amount of adding water based on the temperature. If the outdoor temperature is above 0 degrees, you can choose to add water at night; if the outdoor temperature is below 0 degrees, it is best to add water the next morning to prevent the water outlet from freezing in rain and snow; weather, the amount of water added should be reduced accordingly. If there is still half of the hot water left in the water tank after overnight use, to prevent the heat from dissipating too quickly, you can add water to the water tank. If the weather is nice the next day, fill it. with water On rainy or snowy days, add only 1/3 of the water.
4. Turn on the water flowing from the hot water tap to prevent freezing.
When the temperature drops, youcan turn on the hot water tap a little and let the water sit in the water. The heater drips slowly, keeping hot water circulating through the pipes to prevent water pipes from freezing. However, containers such as basins and buckets should be placed under the tap so that the water can be reused to avoid waste.
5. If the temperature is too low or the solar water heater has not been used for a long time, it is necessary to close the water supply tap and drain the water into the pipe to prevent the pipe from to flow. freeze and crack. If the water heater pipe freezes, it will automatically leak when the temperature rises. You can also use a hair dryer to blow it, or wrap it in a towel and pour warm water slowly. Do not cook it with an open flame or directly scalded. with boiling water to preventthe pipe does not break.
Zhongguancun Online - Four tips to keep in mind to prevent solar water heaters from freezing and cracking in winter
Four tips to keep in mind mind to prevent solar water heaters from freezing and cracking in winter. freezing:
1. Use anti-freeze devices for heating
Some solar water heaters are equipped with anti-freeze devices, as long as they are used quickly and rationally, they can effectively prevent pipes from freezing. frost and cracks. This requires consumers to get into the habit of listening to weather forecasts and make sure to do so when the temperature remains below 0°C. First turn on the antifreeze device to provide preheating protection.
2. Pipe insulation and antifreeze
If the solar water heater is not equipped with an antifreeze device and the temperature is too low, the pipes will freeze et will crack easily. During winter, consumers are advised to carry out maintenance on exposed pipes. For thermal insulation, exterior pipes can be wrapped with insulating materials such as cotton or plastic foam.
3. Correctly choose the time for adding water
Determine the time and amount of adding water based on the temperature. If the outdoor temperature is above 0 degrees, you can choose to add water at night; if the outdoor temperature is below 0 degrees, it is best to add water the next morning to prevent the water outlet from freezing in rain and snow; weather, the amount of water added should be reduced accordingly. If there is still half of the hot water left in the water tank after overnight use, to prevent the heat from dissipating too quickly, you can add water to the water tank. If it's nicethe next day, fill it out. with water On rainy or snowy days, add only 1/3 of the water.
4. Turn on the water flowing from the hot water faucet to prevent freezing.
When the temperature drops, consumers can open the hot water faucet a little and leave the water in the water . The heater drips slowly, which can keep the pipes warm. Circulating water prevents water pipes from freezing, but consumers should place basins, buckets and other containers under the faucet so that water can be reused to avoid waste.
Experts say that if water heater pipes freeze, they will automatically leak once the temperature rises. You can also blow them out with a hairdryer, or wrap them in a towel and slowly pour warm water over them. open flame or scald them directly with boiling water to prevent the pipes from breakingt. If the temperature is too low or the solar water heater has not been used for a long time, it is necessary to close the water supply tap and drain the water into the pipe to prevent the pipe from freezing and does not crack.
