Many people don't know the importance of removing scale from solar water heaters. In fact, scale from solar water heaters needs to be cleaned regularly, just like scale from electric water heater tanks. The editor will tell you about solar water heaters. Complete steps for cleaning.
Cleaning steps
1. First drain the water from the water heater.
2. Remove all vacuum tubes, use a long wooden stick, and tie a cotton fabric ball with cotton rope to one end. The size of the cotton ball should be slightly larger than the inner diameter. of the vacuum tube, but not too big, just feel a little resistance, slowly pass it through the vacuum tube, rotate it, then rotate it. The vacuum tube should be filled with water. Finally, simply rinse it with clean water. Note that if there is not much scale, there is no need to clean it frequently, because during the demoWhen installing the pipe, the sealing ring is easily damaged, so check it carefully before installation. If damaged, replace the sealing ring with a new one. one to make sure there is no water leak.
3. Open the water inlet of the solar water heater.
4. Add the solar water heater descaling agent to the water storage tank.
5. Automatic heating cycle for 20-30 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.
Warm tips
1. Different solar water heaters have different structures. It's best to clean them according to the instructions, or you can find professionals to clean them.
2. Heating the water to around 40 degrees will make the descaling agent more effective.
3. Clean the solar water heater every three months to ensure that the solar energy is in good working order.
4. The process of descaling the solar water heater is very complicated and will also cause damage to the solar water heater. Therefore, if there is not too much scale, the water heater will not work. no longer works properly, it is best not to damage the solar water heater. When descaling your solar water heater, you should also be careful not to use chemicals for descaling, this may corrode the coating of your water heater tank and worsen the oxidation of the water tank coating .
The solar water tank liner is leaking. Can the coating be removed? Can the side cover be opened?
For branded solar water heatersreliable in quality and trusted by everyone, especially those like our brand Taibiao, used for 20 years, we often encounter problems when renovating a house or moving. new house. Tangled in the problem, do you want to dismantle it? Or not move and buy a new one?
1. First of all, it is better to choose a cloudy day, morning or evening for disassembly, because all the hot water from the solar water heater should be discharged before disassembly (to avoid the hot water 'infiltrate). when the pipe is dismantled) burn). If the withdrawal time is noon, the water in the vacuum tube will be emitted, which will cause the vacuum tube to be damaged by strong sunlight and shorten the life of the vacuum tube.
2. It is best to use dishwashing liquid or use soapy water to lubricate the vacuum tube. At the same time, pay attention to the angle of the vacuum tubeand avoid pulling it on the angle to avoid the vacuum tube bursting and hurting people. After the vacuum tube is disassembled, it must be packed in special polyester foam compartments and placed in a special carton to avoid shock during transportation
3. Unscrew the screws installed on the bracket to disassemble the solar water tank. , be sure to handle it carefully when disassembling to avoid denting or damaging the case due to collision, then you can completely disassemble the bracket.
4. If disassembly is completed and must be transported by vehicle, be sure to use cushioning materials such as foam or cotton cloth to wrap and secure each component, especially the vacuum tube. Pay attention to the overall protection of the packaging to avoid impact during transportation, squeeze each other, causing the glass to break.
Depending on the type of reservationsee water it is, if it is insulated with a polystyrene insulation board it can be removed, but if it is polystyrene or polyurethane foam it cannot be removed. The side cover can be opened.
Today, almost all water heater tanks used to store water have several forms of insulation: polystyrene insulation board, overall polystyrene or polyurethane foam insulation . If it is a polystyrene heat insulation sleeve type, the inner tank can be removed. If it is made of an overall foam, it will be difficult to return it to its original shape once removed.
Most of the time, when an electric storage water heater or solar water heater determines that the water tank liner is corroded and leaking, it is directly replaced with a new heater water, because the liner of the water tank itself is made of a stainless steel plateseveral millimeters thick, it is of little importance to repair after a leak. Even if it can be repaired, it cannot continue to be used for too long and the cost will be high. very high.
When it is determined that the repair is of minor importance, it is recommended that the water heater be scrapped and replaced with a new one. In addition, during normal use of the water heater, try not to leave the water tank empty to reduce the risk of the water tank coming into contact with oxygen in the air and slow down corrosion .
