Air energy products have been used abroad for decades, and the technology has already matured. Domestic manufacturers just copy, the technology is similar, and the basic homogenization. Strictly speaking, as long as you have done air conditioning, have the minimum research and development ability and enthalpy difference room and other experimental equipment, it is easy to improve and match the test on this basis, not as high-tech as some manufacturers boast. Most brands under the banner of German technology and American companies are deceptive. Don't trust them. It is best not to be too superstitious about foreign brands for air energy water heaters. The so-called American company's largest heat pump production base in Jiangmen, which was exposed by China Quality Miles some time ago, turned out to be just a screwdriver factory without even the most basic testing equipment, which is the best proof.
It is suggested to purchase air energy water heaters from the following aspects.
First, the authority of technology: see whether the technology of the enterprise where the air energy products are located has been recognized by the industry, whether it has an engineering technology research and development center recognized by the government, and whether it has undertaken or participated in the national air energy water heater scientific research project.
Second, the reliability of quality: an important indicator to judge the product quality of air energy water heater is to look at the compressor, which can be said to be the heart of air energy water heater. In the application of compressors, Panasonic, Mitsubishi, Emerson and other brands are well-known, and some enterprises adopt domestic air-conditioning compressors, so the performance and service life of the units cannot be guaranteed.
Third, the professionalism of the brand: For the air energy industry, some brands only make air energy products, some are transformed from other fields, and some are half-way monks. Therefore, when consumers choose air energy brands and products, they should combine the above two points to judge the professionalism of the brand and the maturity of technology.
4. Superiority of performance: When purchasing air energy water heater products, in addition to comparing the advantages and data of energy saving, environmental protection, safety and other related industries (this is the common function and selling point of all air energy water heaters), the key is to comprehensively consider other additional performance of the products, such as daily cleaning, maintenance, intelligent thermal insulation performance and so on.
5. After-sales supportability: However, consumers can't simply trust the warranty period when purchasing, such as whether there is a special person to check and repair irregularly, how many hours to respond to maintenance, and how many hours to provide on-site service. At present, the industry's brand service commitment period is: 3 years for home machine host and 5 years for water tank.
