What brand of solar water heater is cost-effective?

Don't buy first-line brands, push several models with higher cost performance. You can buy Tsinghua Yang Dan, Beijing Pu Tian, Jiangsu Huayang, Jiangsu Sangxia and Jiangsu Sheng Yuan. Solar energy is a one-time investment, which can wash vegetables and dishes in winter. Large and small maintenance costs are the same, and the big ones are around 3000. I don't know where you are, but you may not have some brands there. Find it yourself in winter. In the process of use, it is very important to arrange and use the water supply time and quantity skillfully for the service life of the water heater. Here are some tips for solar water heaters.

1. When taking a shower, if the water in the solar water heater has been used up and people haven't finished taking a shower, then they can take cold water for a few minutes, and use the principle that cold water sinks and hot water floats to push the hot water out of the vacuum tube, and then they can take a shower.

2. Using the principle that cold water sinks and hot water floats, if there is still a little hot water in the solar water heater after bathing, the cold water can be used for a few minutes, and the hot water can wash one more person.

According to the weather forecast, we can get a satisfactory water temperature. If it is sunny the next day, you can irrigate it; If it is cloudy or cloudy, the upper part of the water tank is filled with water; If it rains, keep the raw water without cold water.

4. After taking a bath at night, if there is still half of hot water with a temperature of nearly 70 degrees in the water tank of the water heater, 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 and weather forecast.

5. Cold and hot water adjustment: water heater water temperature adjustment steps: first open the cold water valve, properly adjust the cold water flow, and then open the hot water valve to adjust until the required bath temperature is reached. In addition, the amount of cold water can be determined by experience according to the weather conditions, and the nozzle should not be pointed at the human body to avoid burns.

6. Wind-resistant measures: the components of the solar water heater are connected reliably, and the wind-resistant performance mainly depends on its installation and fixing method. 7. How to prolong the service life: In order to prolong the service life of the solar water heater, users should pay attention to: after the water heater is installed and fixed, non-professionals should not move or disassemble it easily to avoid damaging key components; There should be no sundries around the water heater to eliminate the hidden danger of hitting the vacuum tube; Regularly check the vent to ensure smooth flow, so as to avoid bursting or deflation of the water tank; When cleaning the vacuum tube 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 water supply to prevent dry burning without water.
