Why is the water collection pipe of the solar water heater broken?

Introduction Why is the water collection pipe of the solar water heater broken? Because he was frozen. 1. Use antifreeze device for heating. Some solar water heaters are equipped with anti-freeze devices, provided they are used promptly and sensibly.

Why is the water collection pipe of the solar water heater broken?

Because he was frozen.

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 and freezing. cracking. They must be used when the temperature remains below 0°C. The antifreeze device must be activated beforehand 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 and crack easily. In winter, it is best to insulate exposed pipes. Use insulating materials such as cotton or plastic foam to wrap exterior pipes.

3. Choose the correct time to add water

Determine the time and amount of adding water based on 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.

Detailed information:

Solar water heater working principle:

< p>Heat absorption process:

When the vacuum tube water heater absorbs heat, solar radiation passes through the outer tube of the vacuum tube, est absorbed by the heat collecting coating, then transferred to the water in the vacuum tube. tube along the inner tube wall. After the water in the tube absorbs heat, its temperature increases and its density decreases and increases, forming an upward force and forming a thermosyphon system.

As the hot water continues to rise and be stored in the upper part of the water storage tank, at the same time the lower temperature water is continuously replenished on the other side of the pipe. repeats, and eventually the entire water tank reaches a certain level.

Flat plate water heaters are generally split type water heaters. The fluid naturally circulates in the heat collecting plate due to the thermal siphon, and the heat radiated by solar radiation on the heat collecting plate is quickly transferred. to the water tank. The water tank uses heat exchangeeur (jacket or coil) which transfers heat to cold water.
