It needs to be cleaned. Cleaning the solar water heater is not only a hygienic habit, but more importantly, it extends its lifespan. If it is not cleaned for a long time, the scale accumulated in the vacuum tube will affect the heating efficiency and hot water quality. If the scale is too thick, it will be difficult to dissipate heat in the vacuum tube, and this may occur. even a risk of bursting.
Cleaning steps:
1. Open the water inlet of the solar water heater and pour an appropriate amount of descaling liquid.
2. Allow the water heater to run automatically for approximately 30 minutes to allow the descaling liquid to fully contact all parts.
3. Open the drain port and drain the cleaning fluid.
4. Once the water tank is filled with water, it will automatically cycle for 2-3 minutes.
5. Drainthe water is circulating and the cleaning job is completed.
1. Solar water heater is a heating device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production . Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share.
2. Household evacuated tube solar water heaters are composed of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collector tubes, which use hot water. to float and cold water to sink. According toprinciple, the water will produce microcirculation to obtain the required hot water.
How to clean solar energy?
Generally speaking, solar energy will have scale after being used for a long time. The scale must be cleaned. about 2-3 years. This can extend the life of the water heater.
To clean the scale, first drain the water from the water heater, open the water inlet of the solar water heater, add the descaling agent of the solar water heater to the water tank. water storage and cycle automatically for 20-30 minutes. minutes to come into complete contact with the descaling solution. For each part, open the drain outlet, drain the cleaning fluid, drain the circulating water, then clean and descale.
Detailed information:
1. When installing a solar water heatere, there may be a smell of dust or oil in the water line. When using it for the first time, you can first open the faucet to remove debris. .
2. The water stored in the solar water heater should be discharged regularly depending on local water quality conditions. Drain time can be selected in the morning when the sensor temperature is lower.
3. The surface of the solar water heater should be wiped regularly depending on the amount of dust in the area. It can be cleaned when it rains. Keeping the water heater surface clean can get higher heat. collection efficiency.
4. When hot water is not used for several consecutive sunny days, the hot water temperature will be very high. When using the solar water heater, please turn on the cold water first, then turn on the cold water. hot water to avoid burns.
MostElectric heating tubes on the market are only equipped with simple thermostats and do not have real capabilities to prevent the system from drying out. Burning function. At the same time, most solar water heaters are installed on exterior roofs. This type of extensive management and technical differences between managers, coupled with the misleading error of some electric heating pipe manufacturers that their products "can prevent dry burning".
As a result, serious accident risks exist since the installation of electric heating pipes in solar water heaters. How to solve the problem of "dry burning" of electric heating tubes? Besides choosing a reliable supplier, you should also add water to the solar water heater tank in winter when solar energy is not used much.
According to the data, if there is no water in thewater tank and the solar vacuum tube is exposed to the sun, the temperature inside the tube can reach about 2500°C and it is easy for the tube to explode. . In winter, the pipes are exposed to the outside. When the weather is very cold, the inside of the pipes freezes and the water cannot be filled. To solve this problem, simply wrap a thick layer of sponge over the water tank pipe. or solar pipe, which can effectively prevent water from not flowing and draining the pipe and bursting the pipe.
Secondly, it is also important to check whether the leak protection device is working properly. Additionally, if possible, clean the water tank at regular intervals. Overall, whether it is an electric heating tube for solar water heater or an electric heating tube for other liquids, it cannot be separated from the liquid and burned dry, otherwise the temperature iThe internal temperature of the electric heating tube will be too high. and the electric heating tube will burn, causing safety hazards.

Solar energy is cleaned in this way: < /p>< p>1. First drain the water from the water heater.
2. Remove all vacuum tubes, use a long wooden stick, and tie a ball of cotton fabric with cotton rope to one end. The size of the cotton ball should be slightly larger than the inner diameter. of the vacuum tube, but not too big, just feel a little resistance, slowly pass it through the vacuum tube, rotate it, then rotate it. The vacuum tube should be filled with water. Finally, simply rinse it with clean water.
Note that if there is not a lot of scale, it is not necessary to clean it frequently, because when disassembling the pipe, the sealing ring will be easily damagedaged. You must check it carefully before installation. damaged, replace it with a new seal ring to ensure it will not leak.
3. Open the water inlet of the solar water heater.
4. Add the solar water heater descaling agent to the water storage tank.
5. Automatic heating cycle for 20-30 minutes, so that the descaling agent solution comes into full contact with all parts.
6. Open the drain port and drain the cleaning fluid.
7. Fill the water tank with water, then circulate it for two minutes.
8. Drain the circulating water, clean and descale.
