Eight precautions for the use of solar water heaters - solar water heaters, eight precautions for use

1. When the weather is extremely hot and the water temperature is extremely high, the water supply valve must be used to limit the pressure to add water. Do not add water after running out of water. It is better to use the water before sunrise in the morning or two hours after the sun sets in the evening, so as to ensure the service life of the water heater. 2. Each water heater has a vent hole. It is normal for water to flow out after the water is full. It will stop when the water supply valve is closed. The vent holes cannot be blocked artificially. 3. The power of electric heating is 1500 watts. If it is used in cloudy days or when the water temperature is not enough in winter, do not plug in for a long time. The power must be switched off when taking a shower. Fourth, when the temperature is not too low, after the water is used up at night, there is still some hot water in the water heater (water in the vacuum tube), which should be filled with water immediately to reduce the internal water temperature of the water heater, reduce the heat loss that night, and make full use of thermal energy. 5. If the temperature is particularly low, the water level in the water heater must be kept above 80%. In case of continuous cloudy days, please try to use the water in the water heater and replenish the water immediately. 6. When taking a bath, if the water in the solar water heater is used up and the person has not rinsed it out, then you can use cold water for a few minutes. Using the principle of cold water sinking and hot water floating, the water in the vacuum tube can be pushed out, and then you can take a bath. . Seven, according to the weather forecast to decide the amount of water, you can get a more satisfactory water temperature, if the next day is sunny, you can fill the water, cloudy or cloudy, the upper half of the tank of water; if it rains, keep the original water and not cold water . 8. After use at night, if there is still half of the hot water at nearly 70°C in the water heater tank, in order to prevent excessive heat loss (the less water, the faster the heat loss), the amount of water should be determined according to the weather forecast; the next day On sunny days, it is full of water; on rainy days, it is 2/3 of the water.
