Solar water heater, how to prevent pipes from freezing in winter?

1. For solar water heaters which are not equipped with heating tapes etc., if the weather is cold, you can open the hot water nozzle or faucet, place a basin underneath, loosen the hot water faucet and little, and let it drip slowly to keep water flowing through the pipes and prevent them from freezing and cracking. Generally, the flow of one pool of water per night can prevent pipes from freezing and clogging.

2. If the temperature is too low or the solar water heater is not used for a long time, it is necessary to close the water supply valve of the water heater and drain the water from the water heater. and the upper and lower pipes to avoid a lack of water due to too low a temperature. Traffic can cause water pipes to freeze and crack.

3. Before winter arrives, carry out a complete inspection of the solar water heater at home, byfocusing on whether the screws at the pipe interface are loose and whether the pipes are disconnected, leaking, cracked, etc. It turns out that the antifreeze device and pipe insulation material of the solar water heater are damaged and need to be repaired in time.

Detailed information:

< p>Other maintenance of solar water heaters:

1. In winter, it is very common for pipes to be frozen. If it turns out that the pipe has frozen but is not yet cracked, this can usually be the case. automatically cleared after the temperature rises. You can also use a hair dryer to blow on the water line, or wrap a towel around the water line and then slowly pour warm water over it. Do not cook it on fire, hit the water pipe, or scald it with boiling water, because. this will cause the pipe to burst.

2. The waterstored 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.

Antifreeze methods for solar water pipes in winter: drip antifreeze method, pipe insulation and antifreeze, using heating antifreeze device and choosing the correct time to add some water.

1. Antifreeze dripping method: Open the faucet at home, place a basin directly underneath, loosen the hot water faucet and let it drip slowly, and the water in the water pipe will continue to flow. . , to prevent the pipes from freezing.

2. Pipe insulation and antifreeze: To insulate exposed pipes, insulating materials such as cotton or lPlastic foam can be used to wrap exterior pipes.

3. 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 pipes from freezing and cracking when the temperature persists. be below 0°C, the anti-freeze device is activated beforehand to allow preheating protection to take place.

4. Correctly choose the water addition time: Determine the water addition time and quantity 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 accordinglysequence.

SunEnergy

Solar energy (solar energy) is produced by the fusion of hydrogen and helium inside the sun to release enormous nuclear energy. The sun's radiant energy is mainly expressed in the form of solar rays. Solar energy is commonly used today to generate electricity or to provide energy for water heaters. Its usage methods include photothermal conversion and photoelectric conversion. Solar power generation is a renewable, energy-rich and universal source of energy.
