How to use solar water heater in the process of using solar water heater, some people will find that if you cleverly arrange the water supply time and quantity, it will play a multiplier effect with half the effort. Users who have just started to use it may not be very clear. After a long time, they will gradually find out the experience and rules. Here are some tips for using solar water heaters:

A. When bathing, if the water in the solar water heater has been used up, and people have not washed it, then you can use cold water for a few minutes, and use the principle of cold water sinking and hot water floating upward to discharge the hot water in the vacuum pipe, you can take a bath.

B. Using the principle of a, if there is a little hot water in the solar water heater after taking a bath, then use cold water for a few minutes, and you can wash one more person with the hot water. (each vacuum tube produces 6.5 or 8 liters of hot water)

C. According to the weather forecast, the water quantity can be determined to obtain a relatively satisfactory water temperature: if the water is full in sunny days, cloudy days or cloudy days, most of the water tanks will be filled; if there is rain, the original water will not be cold water.

D. After taking a bath in the evening, if half of the hot water in the water tank of the water heater is close to 70 ℃, in order to prevent excessive heat loss (the less the water, the faster the heat loss), it is also necessary to determine the water quantity according to the weather forecast. If it is sunny, full and rainy, then 2 / 3 of the water will be added.

E. Function of the auxiliary water tank: the auxiliary water tank is mainly used in the areas with regular water supply and unstable water pressure. The water storage capacity is between 1 / 2-3 times of that of the solar water heater, which is installed on the roof of the building and used together with the solar water heater. The main function is to adjust the water temperature with cold water when bathing. In addition, it can be used as a water storage tank when the water is stopped, and it can also precipitate impurities in the water in areas without running water.

F. Cold and hot water regulation: the water temperature regulation steps of solar water heater are: first open the cold water valve, adjust the flow of cold water appropriately, and then open the hot water valve for regulation until the required bath temperature is obtained. In addition, the amount of cold water can be determined by experience according to weather conditions. Pay attention that the nozzle should not face the human body to avoid scalding.

G. Anti wind measures: due to the reliable connection of parts of solar water heater, the anti wind performance mainly depends on its installation and fixation method. At present, Huangming adopts 8 × galvanized iron wire and extended expansion bolt to fix it, forming a figure of eight at the front and back, with good anti wind performance. In addition, in coastal areas with strong wind, change the support structure, or remove the back plate, and use the steel rope for fixing the pole Fixed, better effect.

H. How to extend the service life: in order to extend the service life of the solar water heater, users should pay attention to the following points in the use process:

1. After the water heater is installed and fixed, non professionals shall not move or unload it easily to avoid damaging key components.

2. No sundries shall be placed around the water heater to eliminate the potential risk of hitting the vacuum pipe.

3. Check the vent hole regularly to ensure that it is unblocked, so as to avoid damaging or shrinking the water tank.

4. When cleaning the vacuum tube regularly, pay attention not to touch the tip of the vacuum tube.

5. In winter, the pipeline shall be prevented from frost crack and the exhaust pipe shall be kept smooth.

6. The solar water heater with auxiliary electric heating device shall pay special attention to water supply to prevent dry burning without water.
