How to clean limescale inside a solar water heater

1. Use white vinegar to clean: first drain all the water in the solar water heater, then remove all the vacuum tubes, pour an appropriate amount of white vinegar into the vacuum tube and soak for about 10 minutes, and then brush back and forth with a brush. Just cross the clear water on both sides.

However, it must be handled with care, the vacuum tube is very fragile; 2. Use professional solar descaler for cleaning: buy a special solar descaler, open the water inlet of the solar water heater, add the descaler to the water tank, and let the solar energy automatically heat cycle for 30 minutes, then the descaling liquid will evenly penetrate into all parts of the water heater. Then open the drain and drain the water, and finally fill up the water and circulate for two minutes, and when the water is drained, the scale can be completely removed.

The steps to clean the drain inside the solar water heater are as follows:

1. Unscrew the nut of the hot water outlet and block the hot water outlet with your hands to prevent the water from flowing out of the water heater. At the same time, unscrew the nut of the cold water inlet and connect the hose to drain the water until no water flows out of the cold water inlet.

2. Remove the hose connected to the cold water inlet, connect one end of the hose to the hot water inlet, and the other end to the faucet, open the faucet and fill the water for 1 minute, and plug the cold water inlet.

3. Put the cold water in the inner tank for a few more minutes, then open the cold water outlet to drain the water, and repeat several times until the discharged water is clean. Screw on the nuts of the cold water inlet and hot water inlet, open the triangle valve, and turn on the hot water from the faucet of the water heater, and close it after the water flows out.

To clean up scale, it is necessary to pay attention to the use of food-grade descalers for household appliances to remove scale, and industrial-grade descalers contain impurities, which are harmful to the body after drinking. Do not use strong acid to corrode clean ditches, use strong acid to descale, corrosive, harmful to household appliances and the human body.

No need to spend money to clean! With just a small method, the limescale can be removed quickly and effortlessly.

1. Open the solar water inlet and pour in the descaling liquid, and the dosage is determined according to the capacity of the solar water heater.

2. After pouring in the descaling liquid, the water heater will circulate naturally for about half an hour, so that the descaling liquid will evenly contact all parts of the water heater.

3. Open the drain outlet, discharge the descaling liquid, and recycle the water tank to discharge the water once after filling it with water again. Pull out the vacuum tube.

4. Clean the vacuum tube many times and descale.

5. After descaling, the installation of the vacuum tube and the system debugging are carried out, and the cleaning is completed.

1. Drain the hot water from the solar water heater.

2. Carefully remove the dustproof sealing ring on the top of the collector tube. If it's dirty, you can flush the top with warm water.

3. Remove the black collector tube. Wear rubber gloves to prevent non-slip and bruises. Grab it with both hands, turn it left and right with a little force, be patient, and when you can turn it, force it upwards to let the collector tube enter part of the tank, then raise the bottom and gently pull it out.

Pay attention to the sealing glass nozzle at the bottom to prevent it from being damaged and losing the vacuum insulation effect.

4. Pour out the water in the collector tube, and pour out the scale at the same time. Remove one, shake it a little harder, and pour it out while it's hot. Then pour water into the spoon and rinse several times with shaking until clean.

5. Take out the rubber sealing ring in the mouth of the water tank. After all the removal is done, rinse with water, especially the inner side, so as to ensure a good seal with the collector tube.

6. Clean the scale of the water tank. With a curved tool, pull out a large piece of limescale and rinse it with a large amount of water.

7. Install the rubber sealing ring. Assist with installation with both hands from inside the two holes, which are placed on the stainless steel edges inside the tank. After that, install the collector tube, prepare a little dish soap dilution, rinse the top of the collector tube with water, dip it in a little dish soap solution, and slowly push the top into the water tank.

Be careful not to hurt the bottom vacuum glass nozzle.

8. Whether there is water leakage in the water addition test. Fill up with water, check for leaks, and it is recommended to drain the first tank of water so that any residual dish soap can be disposed of. If there is no water leakage, just push the dust ring.

The water heater at home has been used for a long time, and there may be limescale residue inside it and needs to be cleaned. So how do solar water heaters clean the scale inside? PChouse will take you to find out.

1. First put all the water in the water tank, then hold the vacuum tube with your hand and rotate it back and forth, and when the sealing ring on the vacuum tube and the water tank is loose, push it into the water tank.

2. When the vacuum tube is completely loose, it can be pulled out of the tank.

3. Pour out the water in the vacuum tube, and then the scale comes out together with the water, the scale in the vacuum tube is mixed with the water, which is different from the thermos cup, the scale of the vacuum cup is sticky around the vacuum tube, and then pour some clean water into the vacuum tube, and rinse it clean, so that the vacuum tube is cleaned after repeating several times, and each vacuum tube is cleaned in turn, and then check whether the sealing ring on each vacuum tube in the water tank is intact, if there is damage, A new seal should be replaced to prevent water from leaking from the vacuum tube seal.

4. Next, fill the water tank with water, when the water flows out of the vacuum tube, then install the vacuum tube to the water tank one by one, and the work of cleaning the scale is completed.

5. To clean the scale in the solar water heater regularly, it is usually decided according to the local water quality situation, and there is no need to clean it too often.

6. In daily life, we should pay attention to the water temperature in the tank when exercising the solar water heater, when the water temperature in the tank is lower than 75 degrees, it is not easy to produce scale, so in summer or spring and autumn, the water temperature depends on the weather conditions, if the sun is sufficient, the water in the tank should be added with use, so that the water temperature will drop with the addition of tap water to avoid the generation of scale.

1. Before descaling, we should first open the water inlet of the solar water heater, and then pour in the descaling liquid, and the amount of descaling liquid is determined according to the capacity of our own solar energy.

2. After pouring in the descaling liquid, turn on the water heater and automatically circulate for 30 minutes, then the descaling liquid will evenly penetrate into all parts of the water heater.

3. Open the drain port of the water heater, discharge the descaling liquid, pour in the clean water again, and discharge the dirty water after the water heater automatically circulates once.

4. Pull out the vacuum tube of the solar water heater, pour out the scale in the vacuum tube, pour the descaling liquid into the vacuum tube, and cycle the vacuum tube many times until the scale is completely cleaned. Be careful when cleaning the vacuum tube, never touch the bulge at the bottom of the tube, if you touch the tube, it will be scrapped.

5. Reinstall the vacuum tube, turn on the water heater and clean it again, knowing that the water flowing out has become clear. Finally, remind everyone that it is best to clean the water heater every 2-3 years, too often will cause damage to the inner tank.
