Million and high-profile response to water heaters "aluminum substitute copper"

For the gas water heater manufacturers to replace the copper material with aluminum material for the core components of the heat exchanger, recently attracted media attention, questioned its reliability and safety. Yesterday, the protagonist of this incident Wanhe water heater made a public response for the first time. Wanhe Group stated in a statement yesterday that the aluminum alloy heat exchanger adopted by some of the company's products is a technological innovation project undertaken by the company. At present, this technology has obtained the scientific and technological achievements appraisal commissioned by the Science and Technology Bureau of Foshan City, Guangdong Province Science and Technology Agency. Consumers can use it with confidence. Wanhe also revealed that at present, they are domestic manufacturers with aluminum alloy heat exchangers used in gas water heaters, and the company will gradually increase the proportion of products using aluminum alloy heat exchangers. It is expected that about 50% of products will be produced in the future. Use this new technology. According to Zhong Jialu, technical director of Wanhe Group, their technological innovation is to realize the use of aluminum as the main raw material of aluminum alloy instead of copper as the main material of the gas water heater heat exchanger, not only to achieve technological innovation, but also has a considerable cost advantage. Can enhance market competitiveness. It is understood that the current copper price in the international market is almost twice as high as the aluminum price, and the serious shortage of copper resources in China restricts the development of a large number of copper-consuming industries including gas water heaters. Wan Hui Group's Brand Management Department Minister Li Huizhen told reporters that in fact, some time ago the media reported that the water heater “aluminum substitute copper” is not accurate, and that this technology is to replace aluminum with aluminum alloy. She said that in order to confirm the stability and reliability of the technical performance of aluminum alloy heat exchangers, more recently Wanhe has sent the second trial of aluminum alloy heat exchanger water heaters to the relevant state agencies for inspection. Event playback In mid-August this year, the Beijing Gas Association stated at an internal meeting that there were phenomena that gas-fired water heater manufacturers began to use aluminum instead of copper to manufacture the core components of their products. The association believes that since the physical properties of aluminum, such as heat resistance and corrosion resistance, are quite different from those of copper, the core components of water heaters may cause problems. Its various indicators have yet to be subject to professional identification and market inspection, and therefore do not support manufacturers. Selling immature technology to consumers for experimentation also reminds consumers to buy water heaters to recognize materials. This view of the Beijing Gas Association immediately sparked attention from the outside world. As Wanhe is a well-known brand that adopts this technology, it immediately became the focus of public opinion. Since then, on the water heater industry, "aluminum substitute copper" right and wrong has also led to the debate between the two camps, which the industry has called the air-conditioning industry after another year after the "copper-aluminum dispute."
