At present, the domestic market in China shows that a 200L air-to-water heater (heat pump water heater) for household use typically costs more than 6,000 yuan. Meanwhile, a 150L model usually ranges between 5,000 to 55,000 yuan. As a result, these units are considered quite expensive, and for many working-class families, they can be seen as a significant investment. This has led to many consumers questioning the cost-effectiveness of such products. However, one common question that arises is: "How long can an air-to-water heater last?" To get a clearer picture, I reached out to Huatian Cheng Electric Co., Ltd., a well-known brand in the industry.
According to an official from China Tiancheng, air-to-water heat pump water heaters generally have a service life of up to eight years. These are highly automated devices, and their longevity depends largely on proper maintenance. Regular checks and timely repairs can significantly enhance both the reliability and lifespan of the unit.
The after-sales service representative from Huatian Cheng explained that maintenance starts with routine inspections. First, it's essential to check the power supply and electrical wiring to ensure everything is secure and there are no abnormal conditions with the electrical components. Any issues should be addressed immediately through repair or replacement.
Next, the water system needs regular attention. This includes checking the safety valve, liquid level controller, and exhaust device to ensure they are functioning properly. This helps prevent air from entering the system, which could otherwise reduce the efficiency of the water cycle and affect the unit’s performance.
Additionally, the pump and water valves should be checked to ensure they are operating correctly, and all water pipes and joints should be inspected for leaks. It's also important to examine the unit’s internal components, including pipe joints and inflation valves, to ensure there are no refrigerant leaks.
If the actual water temperature doesn’t match the reading on the control panel, the temperature sensor should be checked for proper contact. Overall, regular maintenance not only ensures the unit runs efficiently but also extends its service life considerably, offering better value for money in the long run.
