Solar water heaters generally need to be cleaned, inspected and disinfected every one and a half to two years. You can ask professionals to clean them, or you can carry out disinfection work yourself.
Cleaning the solar water heater:
Remove the solar vacuum tube, fill it with appropriate amount of white vinegar and soak it for 10 minutes, then use a brush it out and forward to remove the remaining scale, and simply pass clean water on both sides. But be sure to handle it with care, as vacuum tubes are very fragile.
If it is inconvenient to remove the vacuum tube, you can open the water inlet of the solar water heater and pour white vinegar into the water storage tank. Allow the water heater to circulate automatically for 20 to 30 minutes to allow the white vinegar to come into full contact with all partss, then open the drain and drain the white vinegar that cleaned the scale. Finally, fill the water tank with water and circulate it again for 2 minutes, then drain the circulating water.
Buy a special solar descaler, mix it with water in a ratio of 1:10 and add the cleaning solution to the water tank. If the water heater in the house has not been cleaned for a long time, you can also pour the original solution directly into it and let it soak for 5 to 15 minutes to disintegrate the scale. Let it cycle automatically for 20 to 30 minutes, then drain the cleaning fluid directly from the drain. .Turn on the water supply, fill it with water then circulate it for two minutes, then drain it and that's it.

Working principle of solar water heater:
The heat absorption process of solar water heater relies on the vacuum tube to radiate sunlight to absorb heat. The heat collected coating transfers heat into the water along the tube wall. This helps absorb heat. Once the water temperature rises, hot water rises and cold water falls, forming an upward force. After continuous circulation, a thermal alternation effect is obtained.
Home solar water heaters operate according to natural circulation, without any other force interference. This is work done by the gravity of the hot water and there is no need to take into account the loss of thermal energy. Generally, pipeline circulation is not used.
The usage process involves the top water operation method of the solar water heaterre, using an envelope or coil to operate. When installing, the height requirements of the installation should be taken into account so that it is more convenient to use and maintain the water supply capacity.

Tools/raw materials: descaler, water heater.
Methods/steps:
1. Avoid cleaning in summer. Solar water heaters should be avoided in summer. Sunny weather is not conducive to drying. is easy to live with, and the most important thing is that it is easy to burn. Remember to drain the hot water before cleaning. After draining the hot water, put cold water in it to avoid burns.
2. Operate carefully, use a plastic deck plate to remove the dust seal ring of the vacuum heating tube, remove it from the disassembly space and lift it up, and the vacuum tube can be removed . of the support after separation. Be careful with this step.
3. Stir the PVC pipe. After removing the suction pipe, we can clean the suction pipe. If there is little scale, simply rinse it with water. If the ditch is difficult to clean, use it. a PVC pipe to stir it.
4. Spray water heater cleaning agent into the tank of the solar water heater, then rinse with clean water to remove scale, and finally clean the inner and outer sealing rings and the exterior of the solar water heater .
5. Install the inner seal ring. Install the inner seal ring according to the instructionsdetailed pes. Align the vacuum tube and insert it when the distance between the bottom and the bottom is enough, lower the bracket. and put on the outer sealing ring. Check for leaks. The installation is complete.
Solar Water Heater Cleaning Tutorial
The solar cleaning methods are as follows:
< p>Tools: screwdriver, gloves, dish soap.1. Remove the sealing ring and slowly pry it out with a screwdriver.
2. It takes a lot of effort to dismantle the solar tubes, which corrode over time. Be careful and remove them slowly if possible to avoid scratches.
3. Remove the sewage and dirt in the pipe, use a blunt tool to clean the scale, pay attention to protecting the inner tank, and use plenty of clean water to clean the scale.
4. Dip some detergent thinner on top of the solar tube and rCarefully install the solar tube.
Principles of solar energy technology
Solar energy is generated by the fusion of hydrogen and helium atoms at the interior of the sun to release enormous nuclear energy. is the radiant energy of the sun. Most of the energy needed by humans comes directly or indirectly from the sun. Plants release oxygen, absorb carbon dioxide through photosynthesis, convert solar energy into chemical energy and store it in the plant body.
Fossil fuels such as coal, oil and natural gas are also primary energy sources formed by the evolution of ancient animals and plants buried underground over a long geological period. Energy is usually contained in the earth itself. refers to the energy related to thermal energy inside the earth and the atom.Associated energyto nuclear reactions.
How to clean solar water heaters? Here are the detailed cleaning procedures
1 Use professional solar descaler for cleaning.
Buy a special solar descaling agent, open the water inlet of the solar water heater, add the descaling agent into the water tank, and let the solar energy cycle automatically for 30 minutes. At this time, descaling. The liquid will penetrate evenly into all parts of the water heater. Then open the drain outlet and drain the water. Finally, add water and cycle for two minutes. Once the water is drained, the scale can be completely removed.
2. Use white vinegar to clean
First drain all the water from the solar water heater, then remove all the vacuum tubes and pour in a suitable one. Pour this amount into the white vinegar vacuum tubes, soak it fort about 10 minutes, then scrub it back and forth with a brush and rinse it twice with clean water. But be sure to handle it with care, as vacuum tubes are very fragile.
Notes:
1. Cleaning the solar water heater should be carried out when the temperature and water level are low.
First drain the remaining water, then scrub the glass tube, then loosen the glass tube, remove the water tank and add detergent to clean it.
2. The water tank of the solar water heater is full of scale. You can buy a special descaler to clean it.
Generally, add an appropriate amount, wait for a while, then open the drain outlet to drain all the remaining water, and the scale will be removed.
1. Take out the solar vacuum tube, fill it with appropriate amount of white vinegar and soak it for 10 minutes, then use a brushto pull it back and forth to remove any remaining tartar. , then run clean water through both sides. But be sure to handle it with care, as vacuum tubes are very fragile.
2. If it is inconvenient to remove the vacuum tube, you can open the water inlet of the solar water heater and pour in white vinegar into the water storage tank. Allow the water heater to circulate automatically for 20 to 30 minutes to allow the white vinegar to fully contact all parts, then open the drain and drain the white vinegar that cleaned the scale. Finally, fill the water tank with water and circulate it again for 2 minutes, then drain the circulating water.
3. Buy a special solar descaler, mix it with water in a ratio of 1:10, prepare a cleaning solution and add it to the water tank. 'water. If the water heater in the house has not been cleanedoyed for a long time, you can also pour the original solution directly into it and let it soak for 5-15 minutes to disintegrate the scale. Let it cycle automatically for 20 to 30 minutes, then drain the cleaning fluid directly from the drain. .Turn on the water supply, fill it with water then circulate it for two minutes, then drain it and that's it.
