  The service life of air-energy water heaters can generally reach more than 8 years. Because air-energy water heaters are equipment with a high degree of automation, the unit status should be checked regularly during use. Long-term effective maintenance and maintenance of the unit will improve the reliability and service life of the unit unexpectedly.

    First of all, you should always check whether the power supply of the unit and the wiring of the electrical system are firm, whether the electrical components are acting abnormally, and if any, they should be repaired and replaced in time.

    Secondly, always check whether the water system's water supplement, water tank safety valve, liquid level controller and exhaust device are working properly, so as to avoid air entering the system and reducing the water circulation, thereby affecting the unit's heating capacity and unit operation reliability. At the same time, check whether the water pump and water valve are working properly, and whether the water pipes and water pipe joints are leaking.

    In addition, it is necessary to frequently check the working conditions of the various components of the unit, and check whether there is oil contamination in the pipe joints and the inflation valve in the unit to ensure that the unit refrigerant does not leak. When the actual outlet temperature of the air source heat pump water heater is inconsistent with the value displayed on the unit control panel, it can detect whether the temperature sensing device is in good contact. In this way, regular inspection of the product can not only ensure its efficient and normal operation, but also greatly extend the service life of the product.

 

Air energy water heater maintenance knowledge:

    First of all, the water filter installed outside the hot water machine should be cleaned regularly to ensure that the water quality in the system is clean to avoid damage to the host due to the dirty filter of the unit. At the same time, do not pile up debris around the unit to avoid blocking the air inlet and outlet. The surrounding area of the unit should also be kept clean and dry to ensure good ventilation.

    In addition, when cleaning the condenser of the host, it is recommended to clean the condenser with a hot phosphoric acid solution of 50°C-60°C and a concentration of 15% every two years, start the host's own circulating water pump for 3 hours, and finally clean it with tap water 3 times . It is forbidden to clean the condenser with corrosive cleaning fluid. If the shutdown time is long, the water in the pipeline of the unit should be discharged, the power supply should be cut off, and the protective cover should be put on. When running again, check the system thoroughly before starting up. Moreover, the water tank needs to be cleaned of scale after a period of use (usually 3 months, depending on the local water quality). It should also be noted that silicon-phosphorus crystals can also be used in areas with higher water hardness, and water softeners can be used for water softening treatment.
