To replace the 4-point sealing ring of the electric heating hole of the solar water heater, the necessary tools are as follows:
1. Adjustable wrench;
2. Replacement sealing ring for faucet.
The replacement method is: drain the water, remove the electric heater and remove the silicone ring. Then use your index finger to slowly insert the silicone ring into the groove at an angle, so that one side of the silicone ring enters the groove first, and then insert the whole thing into the groove little by little.
Note: The faucet sealing ring may be a waterproof sealing ring consisting of one or more O-rings, or it may be a string or string wrapped around of the valve core under the soft metal packing nut. wire stuff.
How to clean solar water heaters?
How to clean solar water heaters? Many usesMany people 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
Because the thermal conductivity of scale is very low, hundreds times smaller than that of metal, so the thick scale acts as thermal resistance, leading to a decrease in the heat transfer efficiency of the water heater. 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, scale directly blocks the circulation of water inside the heaterau, which results 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 tube 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
Empty all water from the water heater tankand add the descaling solution diluted according to the instructions. Inject water 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 let it circulate on its own for 30 minutes , so that the liquid containing the descaler. can completely penetrate 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. Firstly, we drain the water from the solar power and then bring it back.Use gloves anti-collision to remove the vacuum tube. Method: Simply rotate it left and right and gently push it up. Some may be corroded and be a bit annoying.
After removing it, pour an appropriate amount of white vinegar into it, let it soak for a while, then use a thin brush to brush it back and forth several 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 into it 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.)
How to clean scale from solar water heater , and how often should it be cleaned?
Generally speaking,If the solar water heater in the house has been used for a long time, dirt will remain on it. For this reason, it should be cleaned, inspected and disinfected about once or twice. years. So, how to clean the solar water heater specifically? PChouse will show you the following steps:
1. First drain the water from the water heater.
2. Remove all vacuum tubes and clean the interior wall. You can fill the vacuum tube with water to clean it faster.
Note that if there is not much scale, it is not necessary to clean it frequently. Since it is easy to damage the sealing ring when disassembling the pipe, you should check it carefully before installation. If damaged, replace the sealing ring with a new one to ensure there is no leak.
3. Open the water inlet of the solar water heater.
4. Add the solar water heater descaling agent to the tankwater storage. Drain the water
5. Select the automatic thermal cycle of the water heater for 20 to 30 minutes so that the descaling agent solution comes into full contact with all parts.
6. Open the drain port and drain the cleaning fluid.
7. Fill the water tank with water, then circulate it for two minutes.
8. Drain the circulating water, clean and descale.
Clean once a year.
1. Tools/Materials
Solar energy and water.
2. Methods/steps
1. Carefully remove the dust seal ring on top of the header tube.
2. Remove the black collection tube.
3. Pour the water into the collection tube and pour out the scale at the same time.
4. Remove the rubber sealing ring inside the water tank mouth.
5. Remove large pieces of tartar.
6. Then rinse the scale from the tankof water with plenty of water.
7. Install the rubber seal ring.
8. Install the collector tube.
9. Press the dust ring.
