Founded in 2006, Zhongguang Electric Co., Ltd. focuses on the field of heat pumps, and has the world's leading ZG air energy automatic foaming line and Singapore LKA professional production line, which is currently the largest air energy water heater production base in Asia. As a "strategic partner of China's aerospace industry" in the air energy industry, Zhongguang has applied a number of aerospace technologies to the field of air energy water heaters, introduced aerospace testing standards, and participated in the drafting of 7 national standards and 2 industry standards.
 
Zhongguang Oates has a solid foundation in technology, but there is little innovation. For example, many products still use inner coil heat transfer technology. The outer coil is often located outside the inner tank, not in direct contact with water, the heating effect is poor but the life is longer, the inner coil is inside the water tank, the water is directly heated, and the heat conduction is faster, but the disadvantage is that it is easy to scale and corrode, damage the compressor, and shorten the service life. At present, only some products of Zhongguang Oates are still using inner coil technology.
 
The product series of Zhongguang Oates is relatively small, and the function is relatively simple. For example, the platinum jue series KF80-1/H220L is equipped with a Meizhi heat pump compressor, which reaches the national level 1 energy efficiency, and the inner tank uses a nano thermal insulation coating, which has good thermal insulation performance, and the heating uses a more traditional inner coil heating, and the maximum water outlet temperature can reach 60 °C. Equipped with a 220-liter water tank capacity, the price is about 8,500 yuan, which is high as an old product.
 
However, the new Xiaoai series follows the pace of the industry, level 2 energy efficiency, the price is not high, 160L capacity KD40/160GCET(S) price is about 9000 yuan, using a simple overall design. The product accessories are provided by world-class suppliers, such as high-quality Panasonic compressors, micro-channel heat exchangers with sufficient heat exchange, enamel liners, imported high-precision electronic expansion valves, etc. R134a refrigerant works in tandem with electrically assisted heating to increase the water temperature to 75°C. With comprehensive features and price, the Xiaoai series is an extremely good purchase choice.
 
In view of the inevitable noise generated when the air energy water heater is working, it is recommended to install the split main unit away from the bedroom, living room and other living areas, and it is recommended to place it on an open and firm flat ground. The noise of the integral product is often much smaller, and the living room, kitchen, bathroom, balcony and other spacious enough areas can be placed, and it can play a certain degree of dehumidification and refrigeration effect. Zhongguang Oates has a 6-year warranty, but there is a lack of online and offline purchase channels in many cities. Before purchasing, it is recommended to check whether there is a physical store in the local area.
