In winter the burst pipe
Home installation of solar water heaters, energy-saving plans is easy, the more cold the more hope to a hot bath at home, but home water heater Shuozhou public Zhang happens to strike one winter, water pipes burst every few days on .
Mr. Zhang in July 2009 to buy a certain brand of solar energy, found in December that year a solar water due to leakage caused by broken 10 cm. After minor repairs, the recovery use. In the winter of 2010 when the pipe burst recurrence of solar phenomena.
One winter burst pipes, the quality of the product itself is not a problem?
Mr. Zhang pulls out a purchase of this business to him when the warranty card, clearly written above: Solar host of quality problems within three years free maintenance. Subsequently, Mr. Zhang repeated contact with the dealer, the dealer to find a variety of reasons do not want to hear live, and said, want to change parts have charged $ 50, otherwise on the matter.
Mr. Zhang reflects the Consumers Association, the coordination of several CASE staff, and ultimately agreed to in accordance with the warranty card business description, be maintenance free.

Through the statistics, the province consumer complaints about solar water heaters are mainly concentrated in the winter can not use the product.
Sigh
The siege of a small brand name products
And State Road in a well-known brands of solar water heater stores, sales personnel \"tube used in ultra-cold tube, firing more than 50%, still take hot water in the Antarctic, as well as installation of pipe insulation against off module, completely solve the heat in winter blocking off pipes frozen pipe problem, use solar energy in winter break the bottleneck. \"Reporters learned that the use of capacity for three or four around the 200L solar water heater, the price at least 3,000 yuan, or even 6,000 yuan. Consumers have to pay an additional parts cost.
Solar market in the provincial capital, the reporter found that nearly half of the brand is well-known products that are not in the containment of many small brands, the brand seems a little lonely in here. Some product names or marks are near the famous, and well known brands to take a similar name, the concept of fuzzy large walking a fine line. Shop in a small brand, the reporter saw the shop stocked with only one product, ask and found, where the price was very cheap, 200L capacity is only 1980 yuan price of the product, including accessories and installation costs.
Because the price gap, market, small shops branded products within the flow of people is significantly larger than the more well-known brand.
A well-known brand\\ s sales staff have also very helpless: \"No way, some consumers are price sensitive.\" According to the said store sales last year, about 300 units, while other nearby small brand products have to much higher sales volume.
Shock
Assembled products in a thousand dollars profit
Province CASE staff, told reporters, resulting in solar water heater one winter lay-off or difficult to use the main reasons: First, some small manufacturers of vacuum tubes, poor quality, small size, resulting in low collection efficiency thermal aquatic systems; second machine antifreeze poor; Third businesses or consumers to assemble their own solar water heater problems are still outstanding.
In this regard, a well-known brand name in Taiyuan Wei, head of the Office of bluntly: \"solar water heater industry, the threshold is too low, as long as the production of can produce! Those little brand no technical content, all assembled products.\"
According to reports, a relatively simple solar water heater works, the use of vacuum tube for solar thermal conversion, and then through the heat insulating layer of water can be, \"as long as the tube is black, can be drying out the water.\"
Industry\\ s low barriers to many workshops have begun sales of solar water heater listed, this is usually the stent, the house of the tank, another of the vacuum tube, assembled together on the sale. But the insulation layer is not thick enough, there is no pipe freezing measures, measures the lack of heating temperature … … this product may also use the summer, but winter weather is cold in our province, frequent water heater pipe cracking, leaking, or even burn out the circuit and other issues , the strike will feel a novelty.
According to insiders reveal, the cost of a solar water heater assembly of only seven or eight hundred dollars, while the OEM sale price is about 1,800 yuan, the profits of a water heater thousand dollars. In this profit-driven, more and more enterprises to squeeze into the solar market. In order to maintain profits this market, manufacturers can only be achieved by reducing costs, and thus vacuum coating thinner, more narrow frame, insulation and even a plastic foam impression.

The introduction of industry standards in the second half
Interview, the reporter learned that the first mandatory national standard – \"home efficiency of limited value and energy efficiency rating\" has entered a substantive stage of operation, expected to launch later this year, to regulate the industry chaos. In this standard, the solar water heater energy efficiency will be divided into three, one of the most energy efficient products. \"Is energy efficiency standards through the winter to see what effect the product?\" Mr. Sun asked consumers. \"We do not know what the specific content, but it is certain that with energy efficiency standards, the advantages of our brand products will be obvious, we are looking forward to the introduction of this standard.\" Surnamed Wei person in charge of the future, consumers energy efficiency can the selection of solar water heaters. High level of energy efficiency of the natural winter effect, this should be a guide, but also allows consumers to regain the trust of the solar water heater industry.

3, the temperature is below 0 ?, the thermal solar water heater can open the tap, so that the slow drip, solar water heater to keep water flow to prevent freezing block.
4, the use of solar water heaters, bath, also pay attention to electrical safety.
