The cold water pipe is connected to the cold water outlet.
Solar water heaters have two pipes. Generally, the hot water outlet is on the left and the cold water inlet is on the right. When installing, connect the cold water pipe to the cold water. the inlet and the hot water pipe to the hot water pipe. The mouth is closed and the two water pipe interfaces will also be marked.
In addition to the upper and lower pipes, the solar water heater also has an overflow pipe, which is mainly used for drainage. When the water heater is full, the excess water will be discharged through the overflow pipe and then simply turn off the water tap.
Working principle of solar water heater
Solar water heaters are divided into vacuum tube solar water heaters and flat plate solar water heaters according to their structural forms. main, representing 95% of the sharet of the internal market.
Home 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 tubes which use the principle that hot water is used. floats and cold water sinks, causing microcirculation of water to obtain the required hot water.
Solar energy generally refers to the radiant energy of sunlight. Solar energy is a renewable energy source in a broad sense, solar energy is the source of many energies on earth, such as wind energy and biomass energy. , tidal energy and potential energy of water, etc.
The basic methods of using solar energy can be divided into four categories: use of light and heat, use ofn of light and electricity, use of light and chemicals and use of light and biology. 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.

The Solar water heater uses sunlight to heat stored water. The water during use is already heated, so the same pipeline can be used for incoming and outgoing water.
Daily maintenance:
1. When installing a solar water heater, there may be a smell of dust or oil in the water pipe. When you use it for the first time, you can open the. faucet to remove debris first.
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.
5. There is usually a filter device at the outlet end of the faucet. Scale and debris in the water line accumulate on this screen. It must be removed and cleaned regmainly to increase water flow. smooth exit.
6. In winter, it is very common for pipes to freeze. If it turns out that the pipe has frozen but is not yet cracked, it can usually be cleaned automatically after the temperature rises. You can also use a hair dryer or wrap a towel around the water pipe, then use warm water to pour slowly and do not cook, tap or scald the pipe with boiling water, as this will cause burst the pipe. Multiple freeze blockages can easily cause pipes to freeze and crack. Pipe insulation measures must therefore be reinforced.
7. Solar water heaters should be cleaned, inspected and disinfected on average every two to three years. Users can also do some disinfection work themselves, such as purchasing chlorine-containing disinfectants and adding them. HASthe water. Pour it into your mouth, soak it for a while, and then release it, which can achieve a certain disinfectant effect.
8. Solar water heaters need to be cleaned inside the vacuum tube every two to three years on average to prevent scale from forming inside the vacuum tube and affecting the heat absorption effect.
9. If the solar water heater is equipped with a special instrument, please pay attention to lightning and electricity protection. Do not take a shower and unplug the electric heater during thunder.
The media output is above the solar side output and the media input is below. The upper outlet is generally the media outlet near the border
What is called here The fluid is hot water, and the middle outlet refers to the outlet hot water (medium).
This is the interface that connects thewater inlet and outlet.
This is the interface for water inlet and outlet.
The fluid is what is heated by solar energy, i.e. tap water
The hot water system is made of the fins inside the flat collector Convert the absorbed solar radiation into thermal energy, causing the temperature of the working fluid in the heat exchange tube of the collector to continuously increase, taking advantage of the characteristics of low density of hot liquid and high density of cold liquid. , through the circulation pipe, between the collector and the water tank. A natural circulation of cold water from top to bottom and hot water from bottom to top is formed. Thanks to this cycle, the water in the water tank gradually heats up. Since the working fluid in the flat collector is a low temperature resistant liquid, it can be kept at minus 40 degrees withoutfreeze. Therefore, even in alpine and cold areas, it can work normally all year round.
