Solar Water Heater Maintenance And Cleaning

1. Regularly clean the system to prevent pipeline blockages and ensure clean water is delivered to the water tank. Under normal circumstances, contaminant discharge is guaranteed for a long period of time. Turn on the pollution discharge valve and flush the water valve to ensure clean water is delivered.

2. Regularly remove dust and dirt from the transparent wrap on the solar collection container to ensure high transmittance and keep it clean. Avoid strong sunlight in the early morning or evening to prevent the transparent wrap from being overheated by cold water. Keep the wrap low and prevent it from being overheated.

3. Carefully inspect the transparent wrap for damage and promptly replace it.

4, for vacuum-tube solar water heaters, if the vacuum level drops, the staves are blank, and the barium or titanium getter pellets are black. This indicates the collection heat pipe needs to be replaced, or the vacuum level of the vacuum tube and glass tube needs to be inspected frequently. 

5. For vacuum-tube solar water heaters, cleaning the vacuum tubes as well as the baffle plates is essential.

6. Inspect the various pipelines, valves, ball floats, and solenoid valves to ensure that any leaks, such as rubber pipe connections, are not present. Repairs must be made immediately.

7. If the collector's heat-absorbing coating is damaged or broken, it must be repaired promptly. Pipes should be coated with a protective coating every year to prevent corrosion.

8. Avoid excessive sun exposure. Exposure to excessive sun exposure will cause the circulatory system to stop functioning. This will raise the temperature inside the collector, damage the coating, and distort the insulation layer of the box body, leading to glass breakage. In a natural circulation system, excessive sun exposure may cause clogging of the circulation pipes. If the water level in the hot water tank is lower than the circulation pipe level due to insufficient cold water supply, the circulation pump may stop working.

9. In all-weather hot water systems with auxiliary heat sources, regular inspections of the auxiliary heat source and heat interconnection are required. For auxiliary heat sources, the leakage protection device must be installed before use to ensure reliability. Otherwise, the system will not function properly. For heat pumps, solar energy heating systems, as well as the heat pump compressor and blower, must be inspected to ensure proper operation. 10. When temperatures are below 0°C in winter, the plate system should evacuate the collector water. Then, the frostproof control system should be activated, and the heat pump circulation system should only be evacuated. The frostproof system does not need to be vented.
