Yes, there is no water in the solar water tank, and when the solar vacuum tube is left in the air, the temperature inside the tube can reach about 2500°C, and it is easy to explode the tube.
The main reason why damage occurs is to understand the working principle of solar water heaters: Solar water heaters convert solar energy into thermal energy and heat low temperature water at high temperature to meet the needs of people in life and production. .hot water consumption.
Detailed information:
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When using it for the first time, you can open the tap. to 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 is cleaned regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can allow for 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 regularlyto increase the water flow. smooth the flow.
6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically 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.
Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
7. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. Users can also carry out some disinfection work themselves. ByFor example, they can buy disinfectants containing chlorine. and add them to the water. Pour it into your mouth, soak it for a while, and then release it, which can achieve a certain disinfectant effect.

First of all, as long as the solar energy is still escaping, you can confirm that it will not explode not.
The commonly used glass tube solar water heater tank itself installed on the roof is a non-pressure container, so there must be a vent on the water tank. As the question says, it's impossible to explode in this situation. Because there is no water in solar energy, only part of the water is stored in the vacuum tube. When the sun is strong, the water boils quickly and steam comes out from the exhaust hole of the water tank. will not have any adverse effect on solar energy.
When there is no water in solar energy, especially when there is no water for a long time, the vacuum tube will air dry. In theory, air drying will damage the. vacuum hose. There is no impact on solar water tanks, but there is currently no conclusive data on the impact on vacuum tubes. I work in this field and the solar power installed at my house has not been used for four or five years. When I returned home two months ago, it was still working fine.
When water pressure is unstable, consider turning on the water as soon as possible when the sun is out. As long as you have hot water at night, you don't need to consider the lifespan of the sun. . The main thing is not to go in the water when the sun is very strong, as this could easily cause the hose to burst, but otherwise there is no problem.
