Water should be added at all times.
Usually, the temperature in the water tank exceeds 100 degrees in summer, which is prone to rust. First of all, you need to prolong the habit of using hot water, including washing clothes, dishes, etc. and add water at any time to keep the water in the tank warm. The water is always full, which can lower the water temperature in the water tank and prevent scale.
If the hot water in the water tank still cannot be used and the water temperature is too high, depending on the water temperature, it is better to cover the vacuum tube of the solar water heater with a sunshade. net and secure it tightly with ropes at the four corners. Size can be determined based on water temperature.

Those equipped with auxiliary heat sources should regularly check whether the auxiliary heat source device and heat exchanger are working properly. For auxiliary heat sources heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, otherwise it cannot be used. When using the electric auxiliary heater, special attention must be paid to filling the water. The volume of water in the water tank should not be less than 50% to avoid dry burning without water. Pay special attention to unplugging the power plug when taking a bath, and it is strictly prohibited to use it when the power is on.
When installing the heating tape, be sure to choose products of acceptable quality to ensure anormal use and reduce hidden dangers. When using the heating tape, be sure to turn it off promptly after defrosting, and try not to use it when the voltage is unstable.

1. If it's to the north, it should be empty. If it's filled with water, it will be. freeze, which can easily cause the heat absorbing pipe to freeze. If it cracks, cover the solar panel with a cardboard box or other covering to avoid air drying.
2. The thermal performance of all sensors decreased after air drying. The thermal efficiency of the solar collector before air drying meets the requirements of national standards, but the thermal efficiency of the solar collector after air drying does not meet the requirements of national standards.
3. This type of air drying problem will not occur with ceramic solar. It is an energye solar integrated into the building, it has the same lifespan as the building and resists air drying. This won't happen with conventional solar power. I'm afraid of air drying.

Advantages of solar energy
1 Universal: The sun shines on the earth without geographical restrictions, whatever the situation. land or ocean is everywhere, no matter mountains or islands, it can be directly developed and used, easy to collect, and does not require mining or transportation.
2. Harmless: The development and use of solar energy will not pollute the environment. It is one of the cleanest sources of energy today, while environmental pollution is becoming more and more serious.
3. Huge: The energy from solar radiation that reaches the Earth's surface each year is equivalent to about 130 trillion tons of coal. Hertotal quantity is the largest energy that can be developed in the world today.
