Volume of complaints is also rising, so that water heaters have been accused of the technology was not mature yet to test its security. However, experts recently interviewed by Shique pointed out that the water heater technology is mature, in Singapore, China and Hong Kong to a very high penetration rate. In the Mainland, but also less mature industry, enterprise quality control also need to improve.
Market goes hand in hand the rapid development of complaints
2004, the national water heater that is less than 10 million units sold, by 2005, this figure will rise to 30 million units, more than 600,000 units in 2006, 2008, 70 million units. Especially in the last two years, that water heater water heater market has become an important force in the industry beginning to take shape. At the same time, industry experts predict: the next 3 to 5 years will usher in the water heater exploding.
However, rapid market development, related complaints are increasing. Ms. Wang said consumer complaints such as Beijing, she June 28, 2008 bought a water heater that, in July after the end of the boot there is not heating failure, looking for someone

Similarly, Hunan consumers have complained that Mr Lo said that he purchased in October 2008 that produced a water heater in Guangzhou, by the end of March this year, began to fail, including

Reporters found that the consumer reflects the thermal heating element water heater problems include scaling, bladder leakage,

Burned components, display a black screen, machine burn, the temperature control switch failure and so on. Complaint, consumers have questioned the water heater less mature technology, there are security risks.
Not yet formed a complete supply chain quality control to be strengthened
For consumers of these questions, the national quality inspection center of electric household appliances container laboratory director Linghong Hao told reporters that the water heater product itself is no problem, technology is mature, there are good prospects. As a compact fashion, heating speed, safe,

Environmental protection and other unique advantages, in Singapore and Hong Kong and other places in China have a high penetration rate. Linghong Hao pointed out that the technical process for instantaneous water heaters more complex environmental requirements on the installation and use of electricity than higher, according to national standards, technical requirements in accordance with product installation and use, it should be said is a high security products. However, the development of this industry in China relatively short time, small scale enterprises to improve product quality control to be some "miscellaneous troops" in the technology and processing technology has been lacking, resulting in mixed quality of products on the market, affecting consumer awareness that water heater.

Quality and raw material selection, but related, that affect the quality of a great cause. For example, some products soon happen with the water leakage, a large part is due to copper material selection or processing flawed result. Copper tube water heater as the channel, are subject to thermal expansion and contraction during each use of physical force, if the copper can not reach the corresponding physical targets, it is easy because of repeated force and fatigue, leading to cracks and cause leakage.
Oulai Ke Zhou Hua, Chief Engineer, Electrical Technology Department that the above problems, the deep-seated roots in the water heater is an emerging industry that has not yet established a complete professional, social supporting system of industry, even not to mention supporting the supply chain.
