2010-7-6 9:44:42
Market, large and small, hundreds of brands of solar water heater products, dazzling, impossible to distinguish between good and bad. In order to enable consumers to choose the best quality, good after-sales service of solar water heater products, solar water heater's special interview with industry experts and ask him to support Return Weapon for consumers.
According to experts, China has now been put in place a number for the solar industry standards and regulatory measures. In the last year, AQSIQ also particularly solar water heater products, a large-scale sampling, and sampling results were released to the outside world, so that consumers have a choice of standard. Among them, the Emperor, and nine were 100 million to become the brand for its superior quality, "good quality products."
By understanding the process of the country and sampling the contents of the summary by the industry and research, advises consumers to select the following steps must be able to buy the product bed of roses.
A look: product quality and technical indicators
1. In general, the vital interests of consumers associated with the thermal performance index is the average thermal efficiency of solar water heaters and heat loss. These two indicators are decided with the heat capacity of solar water heater collector key index. In general, the higher the average thermal efficiency, higher capacity product collector; and lower heat loss, the stronger the ability of thermal insulation products.
2. Careful observation of the coating on the glass vacuum tube, which is called solar selective absorbing coating layer coating, color coating of good quality uniform coatings without scratches, no peeling or shedding phenomenon, the glass did not stone or nodules on the phenomenon, supporting the supporting pieces of glass placed in correct, not loose. If consumers are not relevant expertise, may choose the "three high" tube and other famous brands.
3. Note the control spacing between tubes in general center distance of two or so in 70mm is appropriate.
4. Attention to whether the design of reflector product can take full advantage of the vacuum tube of the absorber, the maximum degree of vacuum can be light.
5. Generally speaking, no sun in the winter and the weather and in line with electric heating devices to use, so also should choose products with the design of electrical safety.
6. Check water tank insulation thickness. Flat 45mm thick insulation layer thickness as a standard to polyurethane foam insulation the best overall. Polyurethane foam is light yellow, a bit like a sponge, foams have a more uniform pore, squeezing his hand a certain degree of flexibility, but the insulation layer is too soft on its lower density, is not conducive to heat.
7. Stent design for domestic solar water heaters should be reasonable and should have sufficient strength and rigidity to ensure an adequate load-bearing capacity. This is especially important in the coastal city last summer, typhoon "Rananim" attack, Wenzhou, many solar water heaters due to wind design and product quality, there are some problems caused Blew, fallen aircraft, vacuum tube broken and other more serious losses. The national sampling number one Wong were 100 million to design brands such as wind capacity to 12 level, worthy of consumer trust.
Second look: Brand protection and service quality
1. The choice of brand to homes, "small" get "big." Brand, is a manufacturer of consumer credit guarantees, Big brand means more and more reliable protection. Some SMEs are left holding the mentality of a quick kill, product quality, after-sales service are difficult to guarantee.
2. Domestic solar water heaters after-sales service is very important. Because domestic solar water heaters are durable consumer goods, and usually installed in the roof, once a fault, the user is difficult to themselves, so after-sales service must be protected. Currently, the market machine free warranty period is generally 3 to 5 years.
Consumers do not understand the product, the best choice for well-known brands and good dealer service and see the national quality inspection reports related products. The national sampling results, the recommended brands, such as the Emperor were 100 million to other companies, has the world's most advanced production equipment and quality testing facilities and after-sales service system through all over the country to provide consumers with comprehensive pre-sales, sales, service, users do not have the product to use for the service during the trouble.
Three to see: the actual needs of their families
1. In the purchase of solar water heater, consumers should also consider the home of the resident population, to determine the purchase of solar water heaters for domestic water capacity size. 40 liters of water per person a general standard is appropriate. In addition, the purchase should be clear to vendors, their nominal water capacity refers to the capacity of all the water is actually available water capacity, the difference between the two.
2. Consumers should also note that we measure a water heater is easy to use, has never been the standard summer winter, summer is also cold, rainy, winter is also hot, as long as the sun, the solar water heater can operate normally. The really good solar water heater is sunshine to rainy days so when a very low intensity can also provide consumers with adequate water. Therefore, consumers in the choice of solar water heater, do not let dealers led by the nose, eyes must be polished, high-quality products selected to fit their own.
The above three points, more and listen more to ask many more, I believe you'll be able to select the solar water heater to the bed of roses.
"Solar water heaters for Purchase"
July 1, China Consumer Association and China Household Electrical Appliances Association officially released "Guide to purchase solar water heaters."
According to statistics, domestic hot water supply and winter heating energy consumption of Chinese urban household energy consumption more than 30%. Use of clean renewable solar energy water heating, both reduce the cost of family life, the pragmatic move, it is an efficient way to alleviate the energy shortage. As we increase awareness of energy saving, coupled with the maturity of solar energy technology, consumers have begun purchasing the use of solar water heater scale. Does your area for the use of solar water heater? How to separate solar water heater? How to determine the size of solar water heater? How to install? To address these consumer concerns, the China Consumer Association with the China Household Electrical Appliances Association has compiled a "Guide to purchase solar water heaters."
China Consumer Association, the co-operation with the China Household Electrical Appliances Association, editor of the "solar water heater selection guide", focusing on issues of concern for consumers. Including the situation in various regions of China in the sunshine, solar water heater basic knowledge of how science and purchase solar water heaters, solar water heaters and appliances to the countryside policies to regulate the installation, proper use and get some peace of mind of the after-sales service, and strive to easy to understand , simple, and allows consumers to learn more about solar water heaters, as consumers purchase and use of solar water heaters the right help.
