Tsinghua Tongfang Solar Energy Common knowledge on water heater maintenance
. The water temperature of vacuum tube water heaters can reach ℃ ~ ℃, and the maximum temperature of flat water heaters can reach ℃ ~ ℃. When bathing, you need to adjust the hot and cold water. Put in cold water first and then hot water to avoid burns.
. Clean the inner tank regularly. During long-term use, trace impurities and minerals contained in the water will precipitate over a long period of time. If not cleaned regularly, the water quality and service life will be affected.
3. Conduct regular inspections at least once a year to carefully detect and eliminate safety performance and other potential hazards.
. When not in use for a long time, turn off the power and drain the water stored in the inner tank.
. When filling the water, the water outlet must be opened. Only after the air in the inner tank is completely discharged can you check whether the water is filled.
. For an all-weather hot water system equipped with an auxiliary heat source, the auxiliary heat source device and heat exchanger should be checked regularly to see if they are working properly. For auxiliary heat sources that are heated by electric heating pipes, you must ensure that the leakage protection device works reliably before use, otherwise it cannot be used.
. When the temperature is lower than ℃ in winter, the flat-plate system should drain the water in the collector and install a forced circulation system with anti-freeze control system function. You only need to start the anti-freeze system without draining the system. of water.
. For your health, it is best not to eat the water in the solar water heater, because the water in the collector cannot be completely released and can easily breed bacteria.
Cause of failure: Tap water pressure fluctuates.
Troubleshooting method: Open another tap water valve less often or use a bathtub when bathing. The outlet water temperature of the solar water heater is too high and the temperature cannot be adjusted. Cause of the problem: The tap water pressure is too low
Solution to the problem: Wait for the water pressure to be normal before taking a bath. Put hot water into the bathtub. Add cold water to adjust the temperature. Then put the hot water into the bathtub. After the water temperature in the bathtub has dropped, a solar water heater is used or the water heater or pipeline leaks.
