Solar Water Heater Maintenance Knowledge

To ensure clean water, clean the water tank and prevent pipe clogging, as in a typical sewage system. To ensure clean water, open the sewage valve and drain the drain valve in the line.

2. To ensure a high transmission rate, install a clear, transparent cover on the solar water heater container. Cleaning should be done early in the morning or when temperatures are low, to prevent the transparent cover from being broken by cold impacts. The transparent cover should not be exposed to strong evening sunlight.

3. If damaged, pay close attention to the transparent cover to determine whether it needs to be replaced.

4. For evacuated tube solar water heaters, always check the vacuum condition within the glass tube. If the tube is broken or the barium tube—i.e., titanium getter black—is damaged, the vacuum tube needs to be replaced.

5. Vacuum tube solar water heaters: In addition to cleaning the water heater, the reflector should also be cleaned. 6. Check for leaks in hose connections, valves, floating ball valves, solenoid valves, and other leaks. Repair them immediately.

7. Protect all brackets, pipes, and paint brushes once a year to prevent corrosion, as they absorb heat from the collector.

8. Protect from sunburn. Excessive sun exposure can cause a known loop circulation system to stop, leading to a drop in the temperature inside the collector, damage to the finish, cracks in the insulation, and deformation of the glass. Sunburn can be caused by clogged pipes. Natural circulation systems can cause the water level in the hot water tank to drop below the circulation pipe, resulting in colder water. Forced circulation systems can also cause the circulation pump to stop working.

9. Installing an auxiliary heat source for all-weather hot water systems requires regular inspection of the auxiliary heating device to ensure it is not malfunctioning or malfunctioning. To ensure reliable operation, the auxiliary heat source must be an electric heating tube, otherwise it cannot be used. For heat pumps, regardless of the problem, timely troubleshooting is required. For solar heating systems, the heat pump compressor should be inspected and the fan should be functioning properly.

10. In winter, when the temperature is below 0°C, the plate system drains the water in the collector. The installation of a cold air control system function only allows the system to start the circulation system without draining the water inside the system.
