A.O. Smith is one of the largest manufacturers of hot water equipment in North America and has a 40-year history in heat pump technology. In 2009, A.O. Smith launched air energy heat pump products in China, similar to electric water heaters, and A.O. Smith occupies a large share in the mid-to-high-end market. A.O. Smith has been featured in almost all heat pump water heater reviews on the Internet, such as ShowerReports.
 
The A.O. Smith Air Energy Water Heater liner uses its patented Jingui coating, which has excellent anti-corrosion and anti-scale ability, which is more durable, and is also equipped with a patented micro-channel heat pump system for a larger heat exchange area and higher efficiency. In addition, there is an innovative intelligent defrost system that can accurately analyze the system status and prevent the heat pump from being affected by frost and reliable operation.
 
Strictly speaking, air energy water heater is not the accurate name of this type of water heater, heat pump water heater is the correct translation of English Heat pump water heater, and the name of heat pump water heater is also used in national standards. Because there is no such thing as air energy, it is just that the heat in the air is carried by a heat pump, and the heat pump water heater points out the key principle. The early air source heat pump water heater was a very accurate name, but later the air energy water heater was used as the mainstream name by false rumors. A.O. Smith's heat pump water heater series is not much, and most of the products are mainly integral.
 
AE-50H5 is the representative product of A.O. Smith split water heater, the product is equipped with Mitsubishi Electric heat pump compressor, the operating environment temperature is between -7 ~ 45 °C, up to the national level 1 energy efficiency, pure heat pump heating water temperature can reach 65 degrees, when the environment is lower than -7 °C, or in the case of using the instant rapid heating mode, the electric auxiliary heat intervenes to work, the machine uses pure electric mode heating, the water tank capacity is 200 liters, the price is about 14,000 yuan, and it is 50% higher than other domestic brand products under the same specifications , cost-effective.
 
The integral products include wall-mounted AEH, silent AEI, HPI that is more suitable for low temperatures, HPW that can be combined with solar water heaters, and CAHP that integrates everything. Among them, the HPI and CAHP series are both level 1 energy efficiency, which is the most recommended product. The HPI series is equipped with the AES adaptive energy saving system, which can not only choose the high-efficiency heating during the peak ambient temperature during the day, but also memorize the user's dynamic water consumption habits and pre-heat before the user's usual bathing time. In addition, the noise level of the product is as low as 40 decibels, which is similar to the quietness in a library, and effectively avoids the noise pollution caused by the installation of conventional integrated water heaters indoors. The product has two capacity options: 150 liters and 180 liters, and the price is around 16,000 yuan.
 
After-sales service has always been the weakness of foreign water heater brands, A.O. Smith not only has a warranty time of only 3 years, but also many faults are not covered by the warranty, which is much inferior to Haier and Midea's all-free service. It is not recommended to buy Smith split products in areas with low temperatures in winter, such as the Northeast, in case they cannot be used normally in winter, and more silent integral equipment such as HPI can be considered indoors with heating.
