Ten points for cleaning solar water heaters

1. Periodically discharge pollution to the system to avoid pipeline blockage. Clean the water tank to ensure that the water is clean. When discharging sewage, only ensure that the water is normal, open the drain valve and pour clean water into the flush valve.

2. Regularly remove dust and pollutants from the transparent cotton cloth on the solar collector, keep the cotton cloth clean, and ensure high light transmittance. The cleaning work should be carried out in the morning and evening when the sun is not strong and the temperature is low to avoid the transparent ring being stirred by cold water.

3. Pay attention to check whether the transparent ring is damaged, if it is damaged, it should be replaced as soon as possible.

4. When operating the vacuum tube solar water heater, it is necessary to check the vacuum degree of the vacuum tube from time to time or whether there are walls in the glass tube, and the barium and titanium getter particles are black, which means that the vacuum degree is obviously reduced and the heat collection tube needs to be removed.

5. In addition to cleaning the vacuum tube of the vacuum tube solar water heater, the baffle should also be cleaned together.

6. Check whether there are leaks in various pipelines, valves, floats, solenoid valves, connecting rubber pipes, etc. If so, it should be repaired as soon as possible.

7. Once the heat-absorbing coating of the collector is damaged or dropped, it should be repaired as soon as possible. This is supported every year, and the pipeline is painted with protective paint to prevent corrosion.

8. Avoid boring sun. Stopping the circulatory system is called boring exposure to the sun, boring exposure to the sun will cause the internal temperature of the collector to rise, damage the coating, and cause the insulation of the cabinet to deform and break the glass. The cause of the blockage may be the blockage of the circulation pipe; the natural circulation system may also be insufficient cold water supply, and the water level in the hot water tank is lower than the water level on the circulation pipe; the pump circulation system may be the reason for the circulation pump to stop working.

9. The all-weather hot water operating system with auxiliary heat source should be maintained regularly to check whether the auxiliary heat source device and heat exchanger can work normally. Electric heating tubes are used to heat the auxiliary heat source. It is necessary to ensure its safe and reliable operation before operation, otherwise it cannot be operated. For the heat pump-solar heating operating system, it is also necessary to check whether the heat pump and the fan can work normally. No matter which part is faulty, it needs to be resolved as soon as possible.

10. When the temperature in winter is lower than 0 degrees, the plate operating system should be discharged into the manifold; install and use the pump circulation system with antifreeze control system function, just turn on the antifreeze operating system;
