The Hong Kong Emperor Ming, Hong Kong Haier ... the name of the emperor has made many consumers mistakenly believe that this is Huang Ming or Haier's company in Hong Kong. In fact, this is just the so-called "edge ball" that some manufacturers have made, in order to mislead consumers. Yesterday (February 13), CCTV's "Weekly Quality Report" revealed that the poor quality solar water heaters were carefully packaged by the manufacturers and sold from Haining to the whole country. These "branded" water heaters have poor insulation performance and short service life. Consumers must keep their eyes open when purchasing.

Hong Kong "brand" price is half lower

The heat preservation effect of the solar water heater is an important criterion for evaluating its quality. The water heater of the Liu Shifu family in Jixian County of Tianjin will strike at night and in the winter, and the faucet will flow out of the cold water. Therefore, CCTV reporters went to the seller, the investigation and interview of the solar water heater wholesale market in Linyi City, Shandong Province. According to the local sales boss, there are two types of "Huangming" solar water heaters: one is produced by Dezhou Huangming Solar Energy Co., Ltd. in Shandong Province; and the other is produced by Hong Kong's Huangming Solar Energy Co., Ltd., called "Hong Kong Emperor Ming". This kind of “Hong Kong Emperor Ming” is sold in the market, which is the brand of Master Liu’s home. In addition to the "Hong Kong Emperor Ming", it also sells branded water heaters such as Haier, Hong Kong and Hong Kong.

Originally, dealers referred to the solar water heaters produced by these manufacturers as “positive cards” and the water heaters marked “Hong Kong” as “branded”. After investigation, the reporter found that the market price of a "positive brand" solar water heater with 20 heat collecting tubes is generally more than 1,500 yuan, and the price of this "branding" is only about 800 yuan. The boss also revealed that the "branded" solar water heaters are not actually produced in Hong Kong.

Hand foaming difficult to keep warm

Haining City, Zhejiang Province is a well-known “hometown of solar water heaters”. CCTV reporters did not find “Hong Kong Huangming Solar” company in the local area, but were informed that “Hong Kong Huang Ming”, “Hong Kong Haier” and “Hang” are sold in the market. Hong Kong's "a variety of "branded" solar water heaters are produced by the local Haining Chenyang Solar Water Heater Factory.

When the reporter found this water heater factory, he found the "Hong Kong Emperor Ming" water heater. These water heaters only bear the name of the Hong Kong company and the address of the Hong Kong Registry. They do not indicate the name of the manufacturer - Haining Chenyang Solar Water Heater Factory. And address - Zhakou Village, Huangwan Town, Haining City. In a workshop-style factory with only five or six workers, CCTV reporters discovered the secret of the water heater not being insulated. Originally, the workers used the manual operation of the water tank insulation layer. Due to the low pressure of the manual polyurethane foaming, it is difficult to close the two foaming centers, resulting in a lot of voids in the insulation layer. The reporter also found that every time a foaming is completed, the worker has to add some waste to the water tank to reduce costs.
