    It is understood from all over the solar energy research experts and scholars more than 200 people attended the Professional Committee of flat plate solar water heater set up activities. China\\ s solar thermal industry association Professional Committee Luo Zhentao, Guangdong Province Solar Energy Association, Dong-Sheng Zhu, made a speech at the meeting.

small workshop drill GB loopholes

Haining family workshop produced a number of cutting corners is also near the famous solar water heater, should strike hard. But the fight is difficult, because there are some obvious loopholes in the system.

    In the solar water heater in the three largest manufacturing base, a seat Haining accounted for, but it is \"bad reputation.\" Recently, the production of some of the solar water heater Haining cut corners, near the famous CCTV and other issues are exposed, exposure of the local authorities immediately of three individual workshops for law enforcement inspection, seized inventory.

Despite the rapid response, but people are still worried: this can not be the real thing? Since 2008, the national media on the solar water heater Haining made counterfeiting critical reports, local authorities were also brainer – but the fact that it is just brainer, after the limelight, if not intensified, said, or at least business as usual. Can not but concern is: solar water heater Haining where the source of fake? IMPACT is the executive is not as weak, or do have some difficulties? After this time a gust of wind, chaos will remain? To this end, the reporter rushed today Haining investigation.

Workshop crude, brand \"big\" questionable quality

Reporters follow the local industry and commerce, quality supervision department staff, to the production of concentrated solar water heater took the town and Huangwan Zhen Yuan.

Yuan Hua Mei in a private house next to the Town, draped over a simple little shed, is rich Yang Solar Co., Ltd. is located. Reporters saw unskilled laborer to the shed only two perforated metal machine dark corner stood four large oil drums and a mixer, the bucket is said to produce solar water heaters were placed insulation additives \"more more methylene phenyl isocyanate \"and\" polyether polyols \", in addition to no what equipment. Shed on one side, stacking a large number of packaged solar water heater, was printed on the box \"Hong Kong United States.\"

Another similar case of two workshops.

These three \"loser\" in common: brand \"big\" small scale. Industry and commerce, quality supervision department on suspicion of false propaganda, there is no mandatory AQSIQ product 3C certification on the grounds, to be seized and the seizure of the product.

Haining City, Tang Jianping, deputy director of Quality and Technical Supervision, told this reporter; \"Today we have a total sample of 19 , the inspection found that there are individual enterprises registered trademark and production to match, false advertising and other issues. Fu Yang, solar limited company\\ s \\ Hong Kong United States\\ , although there are marked on the product and ISO900 certification national 3C certification, but the manufacturers not always get proof of certification, we immediately quarantined the product and we will work with local industry association standards as soon as possible to determine the local business alliances, All future production enterprises must follow this standard, if not standard, will be subject to heavy fines and even cleared out of business. \"

Haining City of Industry, check the brigade staff, said: Recently they and quality supervision departments will be the city\\ s to make a comprehensive survey and found that product quality problems, false hype and \"near the famous\" misleading consumers and other acts, will be severely against.

Knowledge to explain the purchase of articles

August 2010, AQSIQ for the products, sampling, and the results released to the outside world, by understanding the state of the sampling process and content, through a summary of the industry and research, advised consumers to follow the steps below selection, will be able to buy desirable products.

    For a long time, solar water heater industry with low barriers to entry, fake and shoddy products flooded. Emerged in the market in our province hundreds of large and small brands of solar water heaters, dazzling, impossible to distinguish good and bad. August 2010, AQSIQ for the solar water heater products, sampling, and the results released to the outside world, by understanding the state of the sampling process and content, through a summary of the industry and research, advised consumers to follow the steps below selection, will be able to buy desirable products.

First look at the product quality and technical specifications:

First, the thermal performance, the \"average daily efficiency,\" the higher the better, \"the average heat loss coefficient\" lower the better.

Second, detailed observation of the coating on the glass vacuum tube, which is called the solar selective absorbing coating layer coating, good quality coating color uniformity, film no scratches, no peeling or shedding phenomenon, there is no glass stones or nodules phenomenon, supporting the support of glass pieces placed upright, not loose.

Third, pay attention to vacuum spacing between the tubes, usually two in the center distance of 80mm or so.

Fourth, pay attention to whether the product is designed to take full advantage of the absorber tube, vacuum tube can maximize the sunlight.

Fifth, in general, and no sun in the winter weather, you need to use with the electric heating device, it also should be chosen with the design of electrical safety products.

Sixth, check the water tank insulation thickness. Flat insulation thickness should be ≥ 50mm, overall polyurethane foam insulation to the best. Polyurethane foam is yellow, a bit like a sponge, foams have a more uniform pore, squeezing his hand with a certain flexibility, but the insulation is too soft on its density is smaller, is not conducive to heat.

Seven, stent design should be reasonable and should have sufficient strength and rigidity to ensure an adequate load-bearing capacity. Many solar water heater due to wind resistance design and product quality, there are some problems, resulting in blown, fallen aircraft, vacuum crushing and other more serious losses.

Finally, look at their family\\ s needs:

A home should also be considered when choosing the number of resident population in order to ascertain the purchase of domestic solar water heater water capacity size. 40 liters of water per person is generally the standard is appropriate. In addition, the purchase should ask vendors, their nominal water capacity refers to the total water capacity or the actual volume of water can be used, the difference between the two.

Second, pay attention to the winter easy to use as the standard, see the winter can provide enough hot water in winter, water tank insulation effectiveness, rather than price. Therefore, consumers in the choice of solar water heater, do not let dealers led by the nose, must be easy to use as the standard in the winter, all year round, easy to use product selection.

Based on the above factors, see and hear more more more more to ask, you will be able to choose a good product for your home.
