How to replace the vacuum tube of solar water heater:
1. Mix the dishwashing liquid with water one by one;
2. brush the silicone near the bottom end of the water heater tank. Apply a circle around the circle (that is, put the rubber ring of the vacuum tube
3. of the tube with your hands, rotate it and push it up .After the vacuum tube is out, lift the bottom bracket, then pull it down while rotating and it will come out;
4.Remove the silicone ring and check it. is fine, first install the silicone ring, then apply dishwashing liquid to the new vacuum tube, gently rotate it and press it to its original position?
Usage. solar energy
Solar energy generally refers to radiant energy from sunlight. Solar energy is a renewable energy source. there are many sources of energyrgie on different brands of solar water heaters, such as wind energy, biomass energy, tidal energy, water potential energy, etc. The basic methods of using solar energy can be divided into four categories: thermal light use, electric light use, chemical light use, and biological light use . Among the four types of solar energy utilization methods, light-to-heat conversion technology is the most mature, has the most products, and is relatively inexpensive. Such as: solar water heaters, water boilers, dryers, solar cookers, solar greenhouses, solar rooms, solar desalination devices and solar heating and cooling devices, etc. Solar thermal power generation has a higher solar energy conversion efficiency than photovoltaic power generation, butits application is not yet common. In photothermal conversion, the application of solar water heaters has the widest application range, the most advanced technology and the best economy.
Photothermal use: It collects energy from solar radiation and converts it into thermal energy by interaction with matter for use. Currently, the most commonly used solar energy harvesting devices include flat plate collectors, evacuated tube collectors and focused collectors. Solar Power Generation: Large-scale use of solar power in the future will be used to generate electricity. There are two main ways to use solar energy to generate electricity:
1. Light-heat-electricity conversion. In other words, the thermal energy generated by solar radiation is used to produce electricity. GeneraBasically, a solar collector is used to convert the absorbed thermal energy into steam as the working fluid, and then the steam drives a turbine to drive a generator to produce electricity. The first process is light-to-heat conversion, and the second process is heat-to-electricity conversion.
2. Conversion of light into electricity. Its basic principle is to use the photovoltaic effect to directly convert solar radiation energy into electrical energy. Its basic device is a solar cell.
Photochemical use: This is a photochemical conversion method that uses energy from solar radiation to directly split water to produce hydrogen.
Photobioutilization: The process of converting solar energy into biomass through plant photosynthesis. Mainly include fast-growing plants (such as firewood forests), coilseed crops and giant algae.

When removing the solar hot water pipe, pay attention to choosing the appropriate time to avoid burns during disassembly . At the same time, you can also use dish soap to lubricate the heating tube to avoid accidents caused by violent pulling. Here are the disassembly steps detailed explanation.
/
Tips: Before removing the heating pipe, you can open the water supply of the solar water heater, add white vinegar or descaler to the tank of water, then fill it with water and start the automatic heating cycle 20 minutes, then drain the water to remove scale and extend the life of the pipe.
1. First, choose a suitable time. It is best to be on cloudy days, and the best time is when the sun is not strong (morning or evening), because beforet disassembly, all water from the solar water heater must be drained to avoid water leakage in the pipe. and cause burns.
2. Before disassembling the heating tube, it is best to lubricate the heating tube with lye-soaked water. The heating tube should also be pulled gently. If pulled hard, the vacuum tube may burst and injure someone.
3. There is an apron at the connection between the heating pipe and the water tank. If the apron is very tight, you can scald it with hot water first, and then slowly remove the apron, or you can do it. You can wash it with water. Use dish soap to lubricate the gap between the heating tube and the rubber ring for easy removal.
4. After removing the heating tube, it is recommended to put it in a special carton to avoid impact damage during transportation.
