Who \\ s life?

[REVIEW] solar water heater short-lived problem, solar energy market is currently the most common and worrying phenomenon. Some small-scale , there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

Recently, there have been two gentlemen came to a solar energy Co., Ltd., said to re-purchase of , and asked their purchase reason, get four points is difficult to believe but have to answer the letter. First, install a solar energy was more than a year, in particular, sunny weather, the sun one day, not how hot the water; the second, as long as the encounter cloudy or rainy days, even if only one day, put out the equivalent of room temperature water the water; third, stand on the verge of collapse before long, they do not want the victim way reinforcement is not assured continued use; fourth, tank manufacturers do not like can be used as promised 15 years, it took two or three years on leakage phenomenon.

Short-lived solar water heater problems, it is the current solar market, the most common and worrying phenomenon. Some small-scale solar water heater manufacturers, there is no high-end industry equipment, superb technical expertise not only form a small assembly workshop, under the banner name of sorts, with \"regular\" playing the price war.

The most fundamental flaw of these products on the life issues, and some can be used two or three years, some only a few months, there will be a variety of conditions, solar water heater caused a \"short-lived ghost\" is the direct cause There are four key points:

First, the bracket process rough. Solar water heaters stent selection and structural design and installation requirements are very high, professional design and installation of solar energy and protect the life of hard infrastructure.

Some small businesses do not stand a professional production equipment and paint techniques, combined with four recruitment of migrant workers formed the \"Install guerrillas\", both of these installers do not understand the design of piping, water heaters, the main fixed and other professional knowledge, but do not know a post of maintenance, resulting in problems abound. For example, the mounting bracket for fixed water heater parts, big brands use more steel bar, strong, corrosion-resistant, but some manufacturers are using wire fixed, resulting in some areas when confronted with heavy rain, hail and other inclement weather, there are many Solar water heaters will naturally shaky, even crashing to the ground.

Second, poor insulation. Solar water heaters produce hot water during the day and stored in a storage box, if the insulating layer of thermal insulation performance is not good, overnight, rainy days can not be used, or difficult to use. Solar water heater insulation resulting in poor performance is largely due to water heaters, insulation, insulation of hot water temperature determines the quality level and the amount of hot water. Good insulation layer using imported raw materials, such as polyurethane, low thermal conductivity, high temperature; high temperature insulation technology using automatic quantitative foaming, and high temperature aging treatment, lasting and stable high performance insulation.

Some poor materials, high thermal conductivity, foam is not uniform, night temperatures can drop more than ten degrees, rainy days experienced no hot water. Some black-hearted enterprise, in order to reduce costs, even using homemade benzene board, insulation effect plummeted a few months later, in 2012, after almost no insulation.

Third, poor liner selection. Most solar water heater manufacturers have said that the water tank is stainless steel. Also stainless steel, but chromium and nickel in stainless steel are very different.

Good solar water heater using high chromium high nickel stainless steel food grade liner, liner ensures durability, corrosion resistance and strong; inferior to use more low-grade stainless steel liner, the basic nickel-free, corrosion-resistant performance is poor, life is short .

Fourth, vacuum workmanship. Vacuum tube solar water heater core components, solar water heater is the \"heart.\" It directly determines the quality of the entire water heater performance. Performance by the use of vacuum coating technology and cleaning, coating, vacuum, seal and other processes and so on.

According to the Sun Co. researcher, some small business or a small workshop, there is not enough money to put into the tube advanced production equipment, but in order to survive, had to use the most original, most affordable tube. Such a low degree of vacuum tubes, high-quality products only 1 / 100, while the tube a lot of residual impurities and water vapor, in the face becomes hot gas, vacuum reduction. In low vacuum coating stability is poor, the intimal layer on two or three years of aging, loss, leading to a sharp attenuation of collector performance, can not absorb enough heat.

How to solve a series of fundamental impact on the life of the solar water heater problem?

First, governments at all levels to increase policy support for solar energy industry. Although China has long adopted a \"Renewable Energy Law\" and the Implementing Rules and other legal documents, but compared to Spain, Germany and other Western countries, mandatory energy-saving measures, the government promote the use of solar energy and not enough supervision, some high-end products efforts to promote the application is lacking.

Second, the solar industry to strengthen self-discipline. Advanced production equipment and high-end technologies that not all companies can have the strength to go into research and development. Throughout the region around the solar energy distribution, brand-name product has a huge market, they will be low cost, low-quality products to market rough, seriously affected the industry\\ s healthy development. According to incomplete statistics, the market has nearly 300 million units around the solar water heater products are not quality and maintenance support. Low-quality solar water heater to the bad impression left by the consumer impact of the industry\\ s image, it also hinders the healthy development of the solar industry pace.

Third, the use of positive publicity to strengthen the awareness of consumer acceptance. Most consumers choose only by the appearance of solar water heaters, solar water heater which one is better production techniques and products there is no clear understanding. The most unscrupulous manufacturers is to increase the publicity of the conceptual tube, and \"three-cavity tube\", \"three super-pipe\", \"Sanxin pipe\", \"purple pipe\", \"space control\" and other terms fly, a serious disrupt the concept of consumer choice, resulting in consumer products can not be a dispassionate look at the nature.

To this end we call on all kinds of manufacturers to fundamentally solve the problem of weak products with the highest quality products hit the market, all levels of government, the solar industry management organizations should take positive measures as soon as possible to integrate solar energy throughout the production of resources, so that \" short-lived ghost \"solar water heater as soon as possible,\" retired \", so as soon as possible onto the solar energy industry standardization, so that the whole of China and the world\\ s people are fully trust and use of solar energy facilities.

market research

[REVIEW] Although home appliances to the enterprise is a big market, but not all companies straw, it does not fundamentally solve the problem. Home appliances is increasing polarization of the solar water heater industry. The threshold of big business into the home appliances, occupy more and more market share, while the SME market share is getting smaller.

One of the solar water heater market survey:

Low-cost solar water heater cut-off town near Qicheng SMEs

because of its energy saving and welcomed by the general public, but the reporter has learned, most small and medium enterprises in the country concentrated solar water heater Haining, Jiaxing, Zhejiang, this year nearly 70% of the enterprises are facing lay-off semi-shutdown state. This is why?

Jiaxing Haining domestic low-cost solar water heater is now the place where most SMEs. 2008 statistics show that the city\\ s nearly 1100 and the production of machine parts of small family workshops. But reporters learned recently is in Haining, nearly 70% of small and medium enterprises facing shutdown and a half year lay-off status.

Reporters were visited several local businesses, they generally difficult to do business this year. Some factory workers, said this time last year, they are working overtime, and this year, the general day to only a half day.

At present, most enterprises are facing Jiaxing Haining suspension semi-shutdown state, most fundamental reason is that production of water heater companies Haining serious flooding, leading to increased price competition in the market. Statistics show that in 2009 there are thousands of companies into the solar water heater industry. The solar water heater Haining local companies from the original 600 to more than 1,000 acute. These companies to compete for market, hard drive down prices. A large number of dealers began to choose more low-cost water heater, many SMEs have lost the original dealer, order less, there is no business done, the factory can only be halted. It is understood that not only the solar water heater Haining dismal market, this year\\ s overall market conditions are on the decline.

Statistics show that, this year\\ s solar water heater brand big business slowdown in growth, down from 36% last year to 15%, almost the majority of business sales across the board. 2010 January and February, China\\ s solar water heater industry gross margin reached 16.86%, over last year dropped by nearly 1%.

The second solar water heater market survey:

Brand complicated solar water heater you believe Who are you?

Reporters in Haining local survey also found that the local solar water heater brand very much. This gives the industry a cut-throat competition, but also serious damage to the interests of consumers.

Reporters learned that the solar industry, the threshold is very low, and profits 10% -50%, there is a huge space, so many local people have to start a solar water heater business. This also led to the brand clutter of the many. Statistics show that nationwide more than 5000 brands of solar energy, while Henin-Hardenne local brands accounted for one-fifth.

The brand is bringing increased competition, a direct result of low-cost low-order products flooding the market. Reporters were visited several enterprises and found that seemingly the same solar water heater, the lowest prices are very different. The lowest of the liner with stainless iron, cost only 1.5 yuan a ton; the prices of stainless steel with high-quality, cost up to 28,000 yuan a ton. A official said, some companies short-sighted, short time to seize the market in order to achieve the purpose, often overlooked product quality, the pursuit of low cost, low price to hit the market.

Solar water heater tank and the density polyurethane material thickness of the liner business is often used to cut corners, the local manufacturers secretly told reporters that the situation in the industry is very common. At present the large-scale solar water heater Haining are small brand, quality, service and there is no guarantee, and consumers are often difficult to identify which true and false.

Reporters also learned that the industry currently does not have a strict regulatory system, industry standards are not adequate, the market is not standardized, experts recommend that consumers choose solar water heater, or to choose the brand, quality, and service has guaranteed products.

The third solar water heater market survey:

Home appliances can allow enterprises out of the woods?

In 2009, the state of solar water heaters included in one of the products of home appliances. Solar water heaters make this more extensive rural open market. This can allow producers out of the woods? And to the industry to bring some impact?

Reporters learned that a solar water heater production of large enterprises since the successful home appliances business, the business year in their original $ 10 million production line and an additional 50% of the investment. Corporate sales in the year also showed a 100% increase. The national data show that last year policy of home appliances to large enterprises, brand sales growth of 36%. A solar water heater manufacturers official said that during the 2008 to 2009, sales of solar water heater factory they show up 100% of the growth momentum.

Home appliances to the enterprise seems to be unlimited prospects. But the reporter also learned that in the survey, there are a considerable number of SMEs are not entering the ranks of home appliances and business is bleak. A solar water heater production of small family size of less than 100 square meters workshop. As the production of smaller, there is no threshold into home appliances, sales fell by more than half of this year, like this now there are nearly a thousand small businesses nationwide.

Even small and medium enterprises successful home appliances, but because of their problems to the business itself does not guarantee profitable growth, many small and medium enterprises in rural areas of the market in the face of the absence of their after-sales service team, not the quality of the product assurance, corporate sales is not good.

Reporters learned in the investigation, although the home appliances to the enterprise is a big market, but not all companies straw, it does not fundamentally solve the problem. Home appliances is increasing polarization of the solar water heater industry. The threshold of big business into the home appliances, occupy more and more market share, while the SME market share is getting smaller. Some experts said that some degree of home appliances has become shuffle boosters. They also suggested that in future development, enterprises should pay more attention to the size and brand building.

Why in China to promote faltering?

[REVIEW] In the era of increasingly tense energy, s, which should be favored by the people, however, according to authoritative statistics, solar water heaters in China\\ s share is currently less than 10%, and the \"Building Energy\" 15 \"Plan and the 2010 Plan\" requirements of the 2015 National Household penetration of solar water heaters up to 20% -30% target, there is a considerable distance.

Growing tension in the era of energy, solar water heater which should be favored by the people, however, according to authoritative statistics, solar water heaters in China\\ s share is currently less than 10%, and the \"Building Energy\" 15 \"Plan and the 2010 plan\" required by 2015 National household solar water heater coverage reached 20% -30% target, there is a considerable distance.

Solar water heaters as a both energy saving and environmentally friendly products, why not promote it in China?

Not restricting industrial development policy support

Promote the production of solar water heaters in China began in the early 1980s, has gone through more than 20 spring and autumn.

Since 2000, the rapid development of solar energy industry, growth of over 20%. Solar energy industry new opportunities, new opportunities of the most important sign is all levels of government have introduced a policy of supporting the solar industry. Especially since 2006, with the country\\ s attention on energy conservation, to include performance evaluation indicators, more support around the solar energy industry. Shenzhen, Yantai, Guangzhou and other cities, as well as Jiangsu, Hainan Province, has announced the implementation of mandatory installation of solar water heater policy.

Put a policy has reflected a number of provincial and municipal governments commitment to energy conservation, but in the implementation process is not smooth. In May this year, Jiangsu Shuyang access to residential solar water heater tender, the price-point, selected four without extensive market impact, but low-cost solar water heater brands, completely changed the competitive environment in the local market, was purchased Housing and dealers who resisted strong opposition.

Jinan City, Shandong Province, on August 1 this year, began full implementation of solar energy, \"put a order\", the next new 12-storey residential and hotels, s must be integrated with building design and construction.

Professional Committee of China\\ s solar thermal Luo Zhentao that from loaded to put a limit on the solar energy industry is the gospel, but the implementation of mandatory installation of solar water heaters, must have the appropriate standards to follow up, otherwise hidden in the prevalence of quality, there is no corresponding protection the case of measures to implement this policy, it is likely ?????.

January 1, 2006, \"China Renewable Energy Law\" into effect. Introduction of this extraordinary law does not give a lot of renewable energy developers looking to bring in surprise, as the \"Regulations\" has yet to introduce the implementation of the law difficult.

\"Solar thermal industry is the most potential for renewable energy and practical significance of the industry, the future state the main force of conventional energy alternatives.\" As a renewable energy law who filed the motion, National People\\ s Congress Huang Ming calls for national science and sound as soon as possible The solar energy industry to support the development of policy.

Industry disorderly competition impact industrial reputation

Bin County, Henan fraternity house the village the first use of solar water heaters. His home water heater is not easy to use security less than two years, and look for factory maintenance, factory early yellow. Such as Bin solar water heater repair awkward encounter that many people. According to statistics, China\\ s solar water heater has reached more than 3,000 billion yuan of output value while only 10 manufacturers, the top 10 combined market share does not exceed 20%, the vast majority of market share lies in the hands of brand-name companies.

Jinghai County of Tianjin flow in the town alone there are 13 solar energy water heater point of sale, the reporter asked of the asking price, a cheap 1,000 yuan, 5,000 yuan a good brand, quality products from 1,000 yuan to the service are difficult to guarantee.

Weapon professional buying guide

With the development of solar thermal technology, have become essential to our \"family members\", but about water heater to buy, a lot of people but it is ambiguous, what kind of water heater can be used with comfortable, safe, professionals to help answer your questions.

Advantages: solar energy, more environmentally friendly, energy saving, safe and economical.

Disadvantages: complex installation and maintenance problems. In addition, hail, high winds, cold weather, water heater vacuum tube solar collector tubes prone to cracking phenomenon. If there is no electric power Accessibility Accessibility is not doing enough or professional, rainy weather or winter may not work properly.

A wide range of solar water heater product categories, according to different classification criteria can be divided into the following categories. By can be divided into categories: vacuum tube and tablet.

Performance can be divided by the tank pressure: pressure and non-pressure type.

According to the structure and installation can be divided into: one and split.

According to operating mode can be divided into: natural circulation and forced circulation type style.

According to installation location can be divided into: rooftop and balcony style.

Key components

Solar water heater has three main components: water tank, stand, collector.

Tank: the tank is the heart of solar water heater parts, mainly by the shell, insulation layer, interior components, galvanized steel casing or spray usually selected steel materials that not only high strength, corrosion resistance is also good. Select more than 40mm insulation layer of polyurethane insulation materials, fine texture and a good polyurethane foam, foam pore size uniformity. Good water tank generally with a thickness of not less than 0.5mmSUS304-2B food grade stainless steel or enamel steel liner is made of durable anti-corrosion, high temperature, can keep the water clean.

or into IC era

[REVIEW] Intelligent Control (intelligentcontrols) English abbreviated as \"IC\", which is defined as: in the absence of intervention can be driven independently to achieve the control objectives of the intelligent automatic machine control technology. IC era is the era of intelligent control.

Intelligent control (intelligentcontrols) English abbreviated as \"IC\", which is defined as: in the absence of intervention can be driven independently to achieve the control objectives of the intelligent automatic machine control technology. IC era is the era of intelligent control.

Since the 1980s, information technology, the rapid development of computing technology and other related disciplines and mutual penetration, promoting science and engineering research to control the deepening, especially in the 21st century, all kinds was the rapid development of science and technology situation, the human aspects have become more sophisticated, the demand and technology conditions have been met to support the case, the control system to the development of intelligent control systems will become a trend.

Turning to solar thermal industry, with the industry\\ s all-round development of are constantly theory, technology, production change. Compared with the early solar water heaters, solar water heater is more mature now, for consumers, more brands of solar water heaters, selective bigger, better read the form, the collector was increased, the quality is more stable; for distributor business, the better to sell solar water heaters, installation of more systems, and more emphasis on after-sales service of; of production enterprises, greater output, the standard is more standardized, itself a development and growth. When a developed to a stage, the product will gradually produce a higher level requirements. People like living in the material reaches a certain stage, based on the requirements will have on the spiritual life, and how to meet the higher demand for solar water heater solar energy into a production factory is a need to continue research and development, to improve an important topic.

The revolutionary control system

Control of human wisdom that higher organisms are the most talked about a desire, so human service products manufactured by the man himself is bound to be controlled. But with the growing awareness and the changing requirements of the control, intelligent control has become the highest current human understanding.

Combined with the continuous improvement of people\\ s demands, solar water heaters to today, has not only a single product, but a saving of energy and produce hot water system. Almost all aspects of this system have been developed, the capacity of water tank used to meet the different number of people, all kinds of vacuum tube collector efficiency has been increased to almost cap, stand to meet the various needs of various types of construction but the CD …… Alone in the control of solar water heater has been no revolutionary change.

Circles in the pan appliances, there is a control technology deeply influenced the later appliance manufacturing, it is wireless remote control technology, this is a technology developed by the military and later civilian-based, large-scale projects by industrial and agricultural use, Since the use of the appliance industry after entering into the homes of ordinary people, has now become an integral control system.

Early television, to conduct various parameter settings, select different channels, different volume must require users to manually adjust himself forward, not only cumbersome but also with the use of frequent, it will affect the entire television system damage. TV remote control system was implanted, when people look at the TV to change channels, volume, set the parameters up front do not have to be adjusted manually, even if it is lying in bed, need only fingers, use the remote control can be completed, and because it does not have to repeatedly touch the TV, but also to some extent, increased the life span of the TV. This revolutionary application allows simple manual TV from almost disappeared, and the current worldwide TV manufacturers have basically no longer produced manually television, and every TV will be equipped with a wireless remote control. The changes in human intelligence while also applied to other products, such as air conditioning, stereo, DVD and so on. This is a big change control system, but also the future direction of human control systems, intelligent inevitable.

Classification system will be built in China solar water heater

CCTV news channel these days continued attention to the poor sales of solar energy near the famous insider, the reporter learned that, for solar water heaters mixed quality, difficult to identify the status of the consumer, China s relevant departments are speeding up the revision of standards, developed a classification system of solar water heaters.

Reporters found in Haining, Zhejiang, these artisanal producers process backward, poorly equipped, produced shoddy heaters, water heaters and the manufacturers are the most important issue on the liner, the thickness is only about half the national standard.

Experts will greatly shorten the liner thickness of less inner life.

Reporter: If the water tank thickness is 0.3 mm or less what happens?

Professional Committee of China Energy Conservation Association, solar Luo Zhentao: (if) the water quality is not good, or even months to be finished.

Industry experts said that solar water heaters, highly specialized, product logos are not clear, the purchase of solar water heaters, low-quality product deceived most of the rural consumers.

Luo Zhentao: most of the flow of rural areas, is part of the consumer through the water heater products are not so understanding. He need only know that, but the true nature of the product he did not know anything. So he plans cheap, fake and inferior to the things that provide the market.

Experts believe that the current national standard does not require solar water heaters that rivers and lakes of the material and thickness, so some manufacturers advantage of the loophole. The revised standard will solve this problem.

Luo Zhentao: the future will require future modification of the water heater on the plate must be clearly identified, what am I material, what thickness. So consumers can see a very clear which is good, which is bad.

Reporter: This logo will appear in that position?

Luo Zhentao: on the plate, the plate in the tank

Reporter: at a glance.

In addition, the relevant state departments have also started the development of solar water heaters grading standards. Standards after the introduction, when consumers buy solar water heaters have a basis for identification.

Luo Zhentao: our future performance of the solar water heater in accordance with quality grade, one hundred twenty-three, this it, is called home solar water heater energy efficiency rating and evaluation, a two is definitely good. Three is the most basic. Not posted on the brand, that is substandard products. It can not let the market. This to ensure product quality and protect the interests of consumers.

export unity

\"The domestic market could not always foster an international brand.\" Solar water heater, general manager of a Shanghai dealer meeting recently in the solar industry for the domestic point of view, causing many of the industry\\ s resonance.

In recent years, China\\ s solar water heater industry in the \"home appliances\" to achieve rapid growth, but also accelerated the pace in the international market. As of the end of 2010, total exports of China\\ s solar water heater to 150 countries, including the United States, Africa, Latin America and other countries, a total of 230 enterprises involved, and there fifty-six enterprises in overseas factories. Nevertheless, China\\ s solar water heater has never in the international market to obtain the corresponding position and recognition.

Industry experts said that the solar water heater to establish international brands to upgrade the entire industry has become an important task of development.

Bottlenecks in the development of domestic enterprises face both inside and outside

China, as the first national production of , industry seize opportunities for development, but also there have been many problems to be solved.

As everyone knows, China\\ s solar water heater is a very heterogeneous industry, currently there are nearly 5,000 enterprises engaged in manufacturing solar water heaters. Small-scale enterprises and number of living environment led to severe. It is reported that the actual annual output value of more than billion, there are only 10 more than 10 million yuan less than one hundred. Some small-scale enterprises because of poor quality, weak service, relying on a price war to survive, leading to solar water heater price war between companies intensified.

With increasingly saturated domestic market, shrinking profit margins, many companies eyeing export attractive piece of cake, which many many workshops for small businesses. But related survey, there are many solar energy companies to reflect the recent export situation is not optimistic this year, the export price has never been lower than last year, exports fell.

\"Not guarantee the quality, service can not follow up\" has become a foreign consumer markets of China\\ s freeze-frame image of solar water heaters, solar water heaters in China is undoubtedly the international image of a serious injury. However, products in the market, the problems, China solar water heater can find the source of export worries. Needless to say, domestic solar water heater industry, scattered, chaotic, and poor health has become a bottleneck in the development of the industry.

International development to rely on brand strength

\"When companies enter a new market, the brand becomes more important.\" Well-known branding expert, Beijing stride strategy management consulting firm has been general manager Mr. Lu Jiang says in his speech. There are many famous international brands have carved up the mainstream market, consumers are generally not willing to buy unknown brands, especially when these products from a lack of \"national brand\" of the country or region.

Lu Qiang explained that the so-called national brand is the business in some countries or regions through long-term efforts to form in some areas of the country\\ s overall a very high reputation, for example, \"Made in Germany\", \"Italian shoes\", \"Swiss watches \"and, in the international market has a high appeal; consumers even if the manufacturers do not understand this situation, the quality will believe it, this is the national brand strength.

At present, China has a \"Made in China\" brand has meant only low-cost production of \"national brand.\" At this stage of internationalization of Chinese enterprises rely on their own efforts to build the brand, so the difficulty will be larger.

Lu Qiang also pointed out that relying on the product development to gain an advantage, and then driven by the product brand, when customers accept the product, naturally, to accept the brand, such as industry and business in the future will be the most international of the future.

This is exactly the Chinese solar water heater industry has the advantage of data that the Chinese solar water heater to maintain the total accounted for 76% of the world\\ s total, China is not only the production and application of solar water heater superpower, but also the foreign user to select The choice of solar power. And solar water heaters have mastered the core technology in the hands of China\\ s solar energy companies, which are conducive to China\\ s solar water heater industry to successfully enter the international market.

Hold together as a shortcut to enter the international road

Enterprises \"going out\" process, in the end how to go further is more stable? Zhejiang Tongxiang Wangcan Yang, general manager of international new energy markets, said in an interview: \"solar water heaters hold together, without losing the common internationalization is a shortcut. Currently, the majority of domestic solar companies for small and medium enterprises, forces are relatively weak, the lack of a centralized platform for integration of resources. domestic solar companies need to unite and join forces in order to better globalize. \"he said,\" solar energy market through a new international entity of B2B trading platform, the best solar companies to come together the formation of a common external display window, not only to facilitate the foreign buyers come to purchase, but also greatly enhance the solar energy industry between domestic and foreign exchanges and cooperation, expand foreign sales of domestic business channels. \"

This road is an international broad and promising, but still need to explore this road. Domestic solar companies to make themselves stronger first order in the foreign markets to establish our right to speak, in the international gone further down this road stability.

Solar product quality problems not only related to the interests of consumers, but also affect the implementation of the energy saving plan. Therefore, measures must be taken to guide the healthy development of the industry.

This year is a critical year for solar thermal, National Development and Reform Commission in the implementation of all parts of the introduction of the \"solar thermal work to promote the national implementation plan.\" However, in recent years, an endless stream of quality , causing accidents, and even personal injury incidents has also been exposed. In fact, solar energy product quality problems not only related to the interests of consumers, but also affect the implementation of the energy saving plan. Therefore, measures must be taken to guide the healthy development of the industry.

Spring and summer season to pay more than the solar water heater complaints

Recently, many users complained, reflecting the process of buying a solar water heater problems. The day before yesterday, Hankou Liu reflect the new pier, he purchased Thunis solar water heater, in addition to the year of purchase can still be used normally, but after the effect is getting worse, even if the sun is very large, almost no hot water. Liu looking unis marketing personnel of the problem, the other says this is normal at first, later said the plot may be a scale, needs cleaning, but the proposed fees, the amount of 200 yuan.

Similar problems in the solar industry as well.

It is understood as a green solar energy, with the \"environmental, safety, save money,\" and many other advantages, so the more the brand on the market, but the accompanying consumer issues are becoming increasingly apparent. According to \"China\\ s solar water heater consumer usage survey\" shows: up to 41.5% of consumers use very dissatisfied. Among them, block frozen pipes, water charged electric heating, tank corrosion leakage, stent collapse corrosion and other defects become the largest quality consumer complaints.

Wong Ming Group Chairman Huang Mingjiang transfer: a critical moment in the energy saving, if the product quality and safety of the repeated problems, are likely to impact the entire renewable energy.

From Wuhan City Consumers Association of complaints in recent years the situation, to 4,5 per month, the solar water heater complaints began to increase. The reason is mainly technical of some manufacturers, service is not in place, production and marketing of products do not meet the appropriate standards, causing consumers to purchase had a lot of problems.

Deceived consumers brand-name solar water heater

Recently, CCTV \"Weekly Quality Report\" exposure that some of the manufacturers play the \"edge ball\", the poor quality of the solar water heater, carefully wrapped, to mislead the consumer is well-known brands of solar water heaters.

The program shows some of the market as a \"Hong Kong\" the name of the solar water heater, it was revealed that an unknown company from Zhejiang, factory workers to do water tank insulation, the entirely manual, difficult to seal, resulting in a lot of empty insulation layer , but the workers also add to the tank waste, to reduce costs. These do not meet the quality requirements of the water heater, vacuum tube, poor quality, resulting in low collection efficiency hot water production systems; growing in thin insulating layer, can not guarantee that the normal use in the winter; In addition, without purification of the liner also easy to weld corrosion, leakage occurred during use, resulting in water heaters scrapped. However, because these brand-name products than the regular price is low, so it attracted a number of consumers.

The data provided by Wuhan Consumers Association, said that the majority of complaints focused on the quality of , the number reflects the vacuum, \"implosion\" or \"outside the explosion\" caused by loss of thermal efficiency. Professional analysis, due to the production of solar water heaters lower the threshold, so many companies in the fish market. The solar water heater storage tank stamping technology, vacuum technology, control systems, core technology, the average consumer it is difficult to distinguish from the surface.

The industry believes that, after the advertising campaign, trench warfare, the price war, war service and technology after the war, the solar water heater industry, there will be a reshuffle great integration of the situation, a group of small and medium brands will be eliminated in the whitewater market, eventually Competition in the market is that the strength, quality, excellent brand-name products. And consumers in the purchase of solar water heaters, we also must look at the brand name, as to some of the larger, formal shops to buy.

Solar water heater in the event of failure, consumers can not themselves repair, parts costs are high. Moreover, compared to electric water heaters and gas water heaters, solar water heaters on the consumer\\ s own \"is a sense of service\" is not yet mature, and also to some extent, \"connivance\" of the existence of counterfeit products. Meanwhile, the current solar water heater \"three guarantees\" no specific state regulations, the general terms of sale made unilaterally by the manufacturer, quality of service varies greatly.
