How to use solar water heaters
1. When taking a bath, if the water in the solar water heater has been used up and the person has not rinsed it, then you can put cold water for a few minutes, and use the principle of cold water sinking and hot water floating to push out the hot water in the vacuum tube. You can then take a shower.
2. After taking a shower 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 water temperature forecast. Tomorrow is sunny, full of water; rainy day, 2/3 of the water.
3. In order to prolong the service life of the solar water heater, users should pay attention during use: after the water heater is installed and fixed, non-professionals should not easily move or disassemble it to avoid damage to key components; no debris should be placed around the water heater to eliminate impact The hidden dangers of vacuum tubes; regularly check the exhaust holes to ensure smoothness, so as not to swell or deflate the water tank; when cleaning the vacuum tubes regularly, be careful not to damage the tip of the lower end of the vacuum tube; solar water heaters with auxiliary electric heating devices should pay special attention to the water supply, Prevent dry burning without water.
4. It is best to choose the solar water heater when it is not exposed to high temperature. The best time is two hours before sunrise or after sunset. This is because the collector plate of the solar water heater can quickly collect heat and keep warm. Therefore, if the water is supplied to the solar energy under the condition of extremely high temperature, the temperature of the water supply is relatively low and the temperature of the solar energy is high, which will cause the temperature difference to be too large. And cause problems such as explosion tube failure. In daily use, after the water heater is filled with water, try to ensure that it can be heated for a sunny day, so that the long-term sunshine can guarantee the water temperature to the maximum extent.
