How to clean the collector tubes of a solar water heater? The cleaning process is very simple.

1. Take a used towel and lightly wipe the vacuum tube of the solar water heater to make the next disassembly step easier.

2. Wearing gloves, take a slice of bamboo or wood and slide the dust seal ring about 30 centimeters from the upper end of the vacuum tube where it contacts with the solar thermal insulation barrel.

3. When disassembling, start from the outermost part of the solar power, hold the upper middle part of the vacuum tube with both hands, apply slight force, rotate and shake the collector tube left and right, and gradually try to apply more force until the vacuum tube can shake.

4. After you can shake it, hold the tube wall firmly with both hands and push it upwards while shaking it, so that the vacuum tube rotates and rolls upwards , about 10 cm into the insulation barrel. .

5. After the bottom of the vacuum tube is completely separated from the solar bracket, slightly lift the bottom of the vacuum tube, rotate it downward, and slowly remove the vacuum tube. The most difficult is the first. You will feel it after removing one. The following ones will no longer be difficult. Use the same method to remove the remaining vacuum tubes from the water heater.

6. Insert your index and middle fingers into the hole in the insulation barrel and remove the sealing rings from all pipe openings. This completes all dismantling work.

How to clean a solar water heater?

How to clean solar water heaters? Many users have not cleaned their solar water heaters for several years. A water heater that has not been cleaned for a long time will produce a large amount of scale.

First: scale will reducethermal efficiency

PaBecause the thermal conductivity of scale is very low, hundreds of times smaller than that of metal, so the thick scale acts as thermal resistance, causing the heat transfer efficiency of the water heater to decrease. In addition, scale will cause local overheating of the wall of the metal pipe. When the wall temperature exceeds the limit, it will cause local deformation, bulging or even rupture.

Second: The scale will reduce the circulation volume of the water heater

Once the scale is formed in the vacuum tube of the solar water heater, the scale directly blocks the circulation of water inside the water heater, resulting in a slow increase in temperature. The heat in the vacuum tube cannot be transferred inside the water tank.

Third: Scale will shorten the life of the water heater

Scale is attached to the vacuum tubee and is difficult to remove. Frequent cleaning is necessary for descaling, which increases the frequency of maintenance, which is time-consuming, material-intensive and expensive.

Fourth: Scale will cause sensor failure.

The thermal conductivity of scale is low. Once scale forms, the temperature sensing element inside the sensor cannot do so. detect the outside in time. Changes in water temperature cause the displayed temperature to be lower than the actual water temperature.

Use a descaler to clean the insulated water tank

Drain all the water from the water heater tank and add the descaler solution diluted according to the user manual . Pour into the water tank through the vent hole, then fill the water tank to about a quarter of the water level, turn on the water heater and leave it. Circulate alone for 30 minutes to permallow the liquid containing the descaler to penetrate completely into all parts of the water heater.

Open the water heater drain outlet and start filling a large amount of water. When the water level exceeds 50%, at the bottom of the solar water tank, open the electric heater outlet or sewage outlet to start. drain the water, drain the descaling liquid and also refill the water at the same time, until most of the cleaned scale is drained from the water tank and clean water can be released, stop to fill the water.

1. First, let's drain the water from solar power, and then wear anti-collision gloves to remove the vacuum tube. Method: Simply rotate it left and right and push it up slightly. Some may be rusty, which will be a bit annoying.

After removing it, pour an appropriate amount of white vinegar into it, leavez-soak it for a while, then use a fine brush to brush it back and forth a few times, then rinse it with clean product. water.

2. What should I do if it is inconvenient to disassemble the vacuum tube? We can pour white vinegar through the water inlet, then let it circulate and heat automatically for about 30 minutes, then release the water into solar energy. (However, this method is more suitable for new solar energy. If it is more than 5 years old, this method will not work)

Solar water heater cleaning tutorial

Solar water heaters can be cleaned with white vinegar or professional cleaning products When cleaning, you must master its normal operating methods.

Solar water heaters are energy-saving and environmentally friendly, and can meet the hot water needs in daily life. VSHowever, if you want to keep the solar water heater in good working condition, you need to carry out professional maintenance and maintenance. Solar water heaters should be cleaned regularly, and professional cleaning and inspections should be carried out every one or two years. Most of its cleaning will be done by professionals. Individuals can also clean it, but they need to pay attention to the cleaning method and safety.

1. Dip the vacuum tube in white vinegar

Everyone who uses solar water heaters knows that the solar vacuum tube is extremely important. It will collect solar energy. Energy and heat water. When cleaning solar power, you need to remove the solar vacuum tube, add an appropriate amount of white vinegar, shake it well and soak it for ten minutes, then use a brush to pull it back and forth.back to remove it. the scale inside, then clean the vacuum tube with clean water and reinstall it.

2. Clean the water tank with white vinegar

When some homeowners clean the solar water heater at home, they find it particularly difficult to disassemble the vacuum cleaner. In this case, they can use another one. To clean, you can open the water inlet of the solar water heater, put an appropriate amount of white vinegar directly into the water tank, and then let the water heater work automatically for half an hour. . This will allow the white vinegar inside to fully contact different parts of the water heater and then open its drain outlet. At that time, the decomposed scale inside will be flushed out along with the white vinegar. . After draining, add clean water to let the water heater drain. Do this twice and it will be clean to iinterior.

3. Cleaning with professional cleaning products

Solar water heaters can also be cleaned with professional cleaning products. Buy this type of solar descaler and follow the instructions. instructions above in the future. According to the instructions, mix it with clean water to make cleaning fluid, then put it into the water tank of the solar water heater through the water inlet, then let the cycle cycle. solar energy under its action, and wait for it to heat up for 20 minutes. Empty the dirty water from the drain outlet, then open the water inlet, put in clean water, continue to circulate it and finally drain the dirty water. After several repetitions, the solar. The water heater can be cleaned.

The tutorial for cleaning the solar water heater is as follows:

1 When all the water in the tank d The water is drained. , clean each tubeempty separately. Hold it with both hands and turn it back and forth to loosen the sealing ring on the vacuum tube and the water tank, then push it into the water tank.

2. When the bottom of the vacuum tube can be removed from the fixed base, remove the vacuum tube from the water tank.

3. Pour the water into the vacuum tube. The scale is mixed with water in the vacuum tube and rinsed repeatedly.

4. When the water flows out of the hole where the vacuum tube is installed into the water tank, install the vacuum tubes on the water tank one by one and the scale cleaning work is completed.

Cleaning Precautions

Solar water heaters have been vigorously promoted because of their energy-saving and environmental-friendly benefits. the environment, and every household with conditions has installed a solar system. water heater. Solar water heaters, like electric kettlesicals and commonly used electric water heaters, will produce scale and will need to be cleaned regularly, generally once every three years, to ensure the solar water heater's operating efficiency.

The main components of scale are calcium carbonate and magnesium hydroxide, which can be neutralized with vinegar. Therefore, vinegar can be used to clean solar water heaters. There are special solar descalers on the market that do not require it. disassembly. Can be cleaned.

Choose a cloudy day or a day without sun to give yourself plenty of time, as this series is estimated to last around 3 hours. Prepare a pair of rubber gloves to protect your hands and prevent slipping during the entire disassembly and assembly process.
