Intensive solar energy does not supply water, and the water is not hot, there is no hot water, there is abnormal noise, water pipes are broken, vacuum pipes are broken, temperature or water level display is incorrect, water leaks, etc.
Solar manufacturers have summarized the following points for you after sale:
First, fault one: the water temperature is not high in sunny days.
Reason ① There is dust on the surface of the collector tube or a cover above the water heater.
Solution: Wipe the dust on the collector tube regularly, remove obstacles above the water heater or install alternately.
Cause ② The inlet ball valve is improperly closed or damaged.
Solution: Close the water ball valve or replace the ball valve.
Second, fault two: water heater leaks
Cause ① The connecting joint or water pipe is damaged
Solution: Replace the connector or water pipe.
Reasons ② There are sundries between the apron and the liner, and the apron falls off or tears.
Treatment method: in the first two cases, remove the sundries, remove the apron and reinstall it; The latter replaced the apron.
Fault 3: The water tank is not full of water.
Resulting in insufficient tap water pressure.
Treatment: Install the booster pump by yourself.
Cause ② Pipes and interfaces fall off or are damaged.
Treatment: Repair or replace the pipeline ball valve and connector.
Cause ③ The vacuum tube is damaged.
Solution: Replace the vacuum tube.
Cause ④ The upper and lower pipes may freeze in winter.
Solution: Artificial or natural thawing.
The above three points are provided by the solar water heater maintenance department, hoping to help you.
First, what problems should be paid attention to in the use of solar water heaters?
1, pay attention to the water supply time.
2. Determine the amount of water according to the weather conditions to ensure that the water temperature is appropriate when taking a bath.
3. Regularly check whether the pipes, exhaust holes and other parts of the water heater are working normally.
4, serious air pollution or windy dry areas regularly flush the vacuum tube.
5. After the water heater is installed, non-professionals should not easily move and load and unload the whole machine to avoid damaging key components.
Second, how to judge whether the solar water heater is full of water?
Generally, solar water heaters are equipped with overflow pipes, and whether the water is full can be judged according to whether the overflow pipes are draining water. In addition, it can be equipped with a water level controller to automatically give an alarm when the water is full.
3. What problems should be paid attention to in the water supply of solar water heaters?
Because the temperature in the vacuum tube can reach about 250℃ when drying in the air, it must be done before sunrise or half an hour after sunset, when the water tank is dry or water is supplied first.
4. Will the solar water heater burn out if it is not used for a long time?
Vacuum tube solar water heater has high efficiency. On sunny days in summer, the water temperature can reach the boiling point in less than two days. If water is not used for a long time, such as business trip and travel, the water tank will be in a state of high temperature and high pressure for a long time, which will promote the aging of the sealing ring and accelerate the aging and shrinkage of polyurethane. Sometimes, the exhaust is not smooth, and the water tank will be damaged due to excessive pressure, forming scale and shortening the life of the water tank. Therefore, if you are away from home for a long time, you should arrange for others to put cold water on the water surface often, or put a cover on the vacuum tube collector to keep out the sun, and then remove it when you get home.
5. Can the solar water heater take a bath with hot water that is not used for several days?
The water that solar water heaters don't use for a few days is usually hot water, reaching above 70℃, especially in sunny days in summer for more than 2 days, and it will cool down at night, keeping the water temperature at 60℃-70℃ for a long time, which is an excellent temperature for bacteria to breed in water. Therefore, if hot water is not used for a few days or a long time, the water quality is poor and there are many bacteria, it must be discharged.
6. Why are solar water heaters used frequently?
After the solar water heater is put into use, it should be used frequently. It is recommended to use it 4 ~ 5 times a day with an interval of no more than 4 hours. This is because:
① Use water for a long time. For users with lower floors, the water used is actually low-temperature water in the pipeline (the water in the solar water heater stays in the pipeline to cool down); Especially in northern winter, the outdoor temperature is low, sometimes reaching below -25℃, and the water in the upper and lower pipes cools quickly. If it is a six-story building, users on the first floor need to put off a basin of cold water every time, which is particularly wasteful. It would be better if they used it often.
② It can effectively prevent freezing, so that the upper and lower water pipes always have a heat source, and the insulation layer can effectively prevent freezing. In the northern winter, many people also use the method of slightly opening the valve of the water heater to prevent freezing indoors.
