Industry insiders burst the industry's unspoken rules The originally calm solar water heater market has recently been bombarded with blockbusters. On August 10, Huang Ming, the chairman of Huangming Solar, unveiled the industry's shady scene, and set up a “solar industry strong potential netâ€, vowing to “except the potential to reveal the black†to the end. "Now the national standards and industry standards are recommended, lack of mandatory security provisions, lack of supervision, leaving a lot of room for cheating for solar water heater manufacturers." Huang Ming said that the solar industry will be disclosed in the future. Unspoken rules, including engineering bidding, sales, accessories, manufacturing, material selection, installation and maintenance, all of which are of shady quality, while pushing for national mandatory safety standards. Three sins: fire, explosion, fall On the afternoon of August 8, this year's No. 11 typhoon "Anemone" approached Wuxi and the wind raged. Some netizens reported that a solar water heater on the roof of a residential building in the Donghe Garden Community in the center of Wuxi could not withstand the typhoon and fell from the 7th floor. Fortunately, the downstairs of the water heater is a green belt, otherwise the consequences will be unimaginable. In addition to falling from a high altitude, fires caused by solar water heaters are not uncommon. In June of this year, five or six water heaters were installed on the roof of a dormitory building of Taiyuan University of Technology. One of the "Samp" brand water heaters and electric heating pipes suddenly spontaneously ignited, and a thick black smoke emerged. The lack of solar water heater standards leaves "cheating space" If the fall and the fire make people sweat, then the explosion is even more daunting. On the morning of July 28 this year, the solar water heater of a resident in Shijiazhuang City suddenly exploded and fell from the roof of the sixth floor. A bicycle downstairs was smashed, the tank liner was cracked, the vacuum collector tube was broken, and the iron bracket was deformed. Fortunately, it did not cause injury to passers-by. After the incident, the user of the water heater came to the dealership where he purchased the "Shenguang" brand solar water heater, but it has been changed to sell the door of other brands of solar energy. Subsequently, she kept calling the phone of a manufacturer in Beijing on the solar casing, but the other party was always busy. Huang Ming disclosed to reporters the safety hazards of two solar water heaters: the first is “cause from the sky†– because the brackets are not strong, the last few typhoons, thousands of solar water heaters fall; the second is “fire Camp" - More than 200 fires occurred before 2009 due to the installation of the electric heating belt. In fact, Huangming solar water heaters also exploded in June this year. Some experts in the industry believe that the solar water heaters that exploded in Huangming were caused by mistakes in installation technology. Analysis: Standard missing leaves "cheating space" Why are the safety problems of solar water heaters so frequent? It is understood that the solar water heaters currently marketed in China do not need to be tested separately. As long as the enterprises produce according to national standards, they can promise to guarantee the quality of products and can go on sale. The solar water heater industry lacks consumption. The mandatory standard of safety is the fundamental cause of the current quality chaos.
