How to ensure the quality of ?

[REVIEW] solar water heater is a family durable \"hybrid\" consumer goods, can also be labeled \"new energy appliances\", is a home appliance industry, one of four kinds of water heaters. Drop-style tank and collector are installed on the roof, wind and rain and sun, maintenance difficulties, it is more demanding in quality.

    Household durable solar water heater is \"hybrid\" consumer goods, can also be labeled \"new energy appliances\", is one of the appliance industry four kinds of water heaters. Drop-style tank and collector are installed on the roof, wind and rain and sun, maintenance difficulties, it is more demanding in quality.

    In each analysis of the industry\\ s own problems, how to ensure product quality is a question worth considering.

    Standard: National since 1991 has been released of solar thermal standards (including the industry standard) ten, but twenty years of industrial development, and practice the standard of proof too low, and a serious lack. Useful to have on the heat according to the average heat loss of eligibility requirements and vacuum tube solar absorptance, hemispherical reflectance of the eligibility requirements, as long as the reduced collector area to maintain the original water tank capacity, Nissan 1500 coating, the exhaust off the assembly line production can be reached. This is a large number of low-end manufacturers offer cutting corners.

    Detection: According to the survey, production and sales in 2000 yuan of small workshops, small businesses are almost no self-test equipment, even if only some of the majority of dress facade, national sampling Lunbu Shang, local sampling failed to fine money, and supervision and sampling the former tend to Leak, may surprise some to cope with a number or zero to do better to buy dozens of vacuum tubes coupled with the root can also be escaped.

    Management: Quality Management System ISO, electrical safety, CCC, CE, environmental certification and other companies are full, but most only for publicity, the real action is in the scale of the enterprise, for small workshops, small business was virtually nonexistent. Many companies also have post with no quality control, as well as the use of false, expired certificates.

    Quality: The quality of solar water heater is finished performance, life cycle, security, judged according to the standard. Useful to have the heat on the level of the same quality with a high degree of sunshine, the latitude and longitude, used to detect different errors with a large, difficult to judge, so I graded energy efficiency standards for labeling some questions. Check the water quality of the hot water is discharged two days later still meet the health standards of the water, not only rely on visual inspection, then how to use water during the guarantee?

    Parts: the upper reaches of the supply of parts suppliers, small businesses tend to look at the price small workshops to see the relationship, without testing, the standard itself is still missing, especially the difference between good and bad quality of the vacuum tube is too great, and control sensor on the instrument, has been broken through the dealer and consumer users of the heart, not with the factory, the market and very messy, good or bad water quality at least one year or even three months after to repair.

    Services: There is now a common problem, the factory just to sales, even if it is some of the brands they simply do everything possible to end Give a man a fish to sell, but can not delegate to fish, how to install how to maintain good service?

    As a brand product is finished, water pipes, fittings, control instruments and other parts of the supply should not be difficult in these kick to the distributor. Expansion tank suction deflated customer complaints and bad, may not be the product quality problem but caused by the installation, the results of the play to end it passed to the user much dissatisfaction. Installation how to regulate? Installation requires the user to specify the correct way to use the factory has responsibility for training.

    Finally a word, while the factory in the impulse, should pay attention to product quality and perfect after-sales service.

    Solar Energy Industry Association, Shandong Province, the standards for to make the upgrade and standardize. Jiaxing Solar Energy Industry Association of the relevant component parts of solar water heaters, the Quality Alliance standards are being developed on the basis of the standard will soon be promulgated. This shows that our industry associations have been really in their functions, let us work together now!

Poland and Spain market scan

[REVIEW] Poland, Spain, solar water heater market scan.

    Poland

    With energy prices and a number of manufacturers to enter the solar market in Poland in 2007 and 2008 has been rapid development. In 2009, despite economic slowdown in Poland, but did not go into recession, there are still 21% of the solar market growth.

Growth was mainly due to sales of flat plate collector driven, because the collectors are often installed in commercial buildings, and commercial construction market in 2009 have a larger growth. Flat plate collector is more suitable for use in the summer. In Poland, the flat plate collector mainly uses include seasonal provide domestic water (such as recreation centers or sports center), year-round hot water for indoor or outdoor swimming pool to provide water for agricultural purposes and to provide hot water heating and other way to provide a combination of seasonal heating for housing (eg, solid fuel boilers and heat pumps or combined). Copper is the main flat plate collector absorbing material, the use of aluminum less.

Vacuum tube collector in 2009, the growth rate of about 3.5%. Most of this product installed in the civil construction, and the new civil construction market in 2009 increased more slowly. Vacuum tube collectors are welcome in the civilian market, mainly because in the Polish market, the tube is considered to be very efficient products, especially when used in winter; same time, the vacuum tube products can support the entire heating system, and not just to provide hot water. The original vacuum tube products are imported from China, the price is very cheap but very good quality, often a problem. This makes the vacuum tube products to poor people\\ s first impression. However, this negative view of people in the past few years been a big change, because the product quality has been greatly improved, and better energy performance, save consumers a lot of energy costs.

Thus, the current trend is that more consumers will choose vacuum tube collectors, especially in small houses. In large projects, the flat-plate is still the preferred products, because when applying for subsidies, this product more in line with requirements, but also in large projects, the use of flat-plate collector is more efficient.

Solar energy market in Poland, vacuum products are mainly divided into the U-tube and heat pipe, which accounted for most of the heat pipe. The use of U-tube increase in 2008, but have declined in 2009. This is mainly because the main use of the U-tube to switch suppliers Nibe Biawar heat pipe. U-tube is more efficient but the prices are higher. Market products are basically forced circulation systems, heat siphon products in this market are very rare.

2008 and 2009, most of the solar energy products in Poland are installed in new buildings. This is more economical for the user, because from the outset as a ing system can be considered part of one. Therefore, many solar manufacturers to the Housing Institute, designers sell their products.

Replace or upgrade existing heating systems also provide opportunities for the solar market. A solar energy system usually with a combination of existing heating systems, to improve its efficiency and reduce energy costs. Many boiler manufacturers of solar products has been added to the scope of their products.

Non-civil construction market in the past few years have been greatly increased, mainly supported by the subsidy program EkoFundusz. Provide hot water for non-civil construction in the near future there will be a larger development. Hotels, schools and hospitals are the most commonly used large-scale solar systems where. There are many developers have installed solar energy systems in new homes, reducing the cost of household energy bills as a selling point. Although not many developers do, but this way is very optimistic about the prospects.

The future, wholesaler distribution channel is expected to shift from building contractors, because the latter from the office to receive more orders for investors, most of these investors are large public building or project investors. Sub-contractor to install the product to the installer, the installation of local chambers of commerce from wholesalers or dealers nationwide in local stores to buy solar energy products.

Not all consumers are aware of the potential purchase of the solar system will enjoy lower interest rates. Major manufacturers and installers should allow more consumers aware of this, and tell them how to obtain these loans. Public institutions can apply for subsidies for large projects, the manufacturers of these units should be in the process of application for assistance.

industry go?

Honor went to domestic products abroad, whether in products, technology, brand and other aspects need considerable upgrade and long-term promotion. To dominate this trend, and only increase R & D, and gradually narrow the gap with the international solar technology, product quality and technical content by the win, or a technology leader in the future will face tremendous pressure at home and abroad enterprises. Accelerated pace in the international situation, the industry is about to face global competition, firms reduce the number of only R & D and sales channels with those who have a chance to win advantage.

    China\\ s development of solar water heater is one of the earliest and large-scale renewable energy industry. Today, China has become the world\\ s production and sales of are the largest countries. According to the Solar Energy Society released the latest data show that the solar water heater production to the national rate of 30% annual growth, annual production of solar water heaters in 2009 exceeded 40 million square meters, accounting for 50% of the world, to maintain capacity of 145 million square meters, accounting for about 70% of the world\\ s total, is the world\\ s largest-scale application of solar water heaters country.

However, the recent CCTV news channel in the \"Weekly Quality Report\" column for the poor quality OEM solar water heater Haining conducted a special report, once again exposed our solar water heater industry in serious problems. This allows us to focus attention once again to the domestic solar water heater industry\\ s future development path Gairuhezou good on this issue.

Problematic domestic market, competition

The development of domestic solar water heater industry, there are many problems, which is particularly noteworthy that the survival of the current situation of solar water heater business is very worrying. Nearly 6,000 in the domestic solar water heater companies, with large-scale production and the real R & D capabilities of business less than 20, the rest are mostly small workshops and some local-name companies. Product testing, but related, quality management, confusion, backward production technology, dumping, cutting corners and so prevalent in these small businesses, resulting in solar water heater market order and chaos, there are many hidden dangers, some companies even facing a crisis of survival.

As we all know, every industry will have their own market segments, while in terms of China\\ s solar water heater market, able to reach consensus on three major markets: the rural market, urban and international markets. In recent years, China\\ s solar water heater in the home appliance industry, this \"fast track\" to achieve rapid growth, but has not been in the international market due status and recognition. Over the years, the development of solar water heater business in rural markets rely mainly on the rigidity of demand pull, but after 10 years of development, the promotion of solar water heaters developed areas of the country\\ s rural solar energy market has become saturated, especially in Jiangsu, Zhejiang, Shandong, Henan province solar energy consumption. In the urban market, because most residents lack of understanding of solar water heaters, installation of the property limit urban management department, the city paid insufficient attention to the construction sector, prices discourage consumers more difficult to solve, and many other reasons, market development difficult.

First half of 2010, solar water heater industry, ushered in the most severe market test, the number of manufacturers dropped from 5,000 last year to more than 2,800 today. Data also show that eighty percent of the solar water heater companies have varying degrees of declining sales, inventories and other issues, the solar water heater industry profits may be declining. From the sustained and healthy development of future industry perspective, solar water heaters must go abroad, to establish an international brand, to promote the Chinese solar energy from solar power to power.

International market is full of challenges, prospects

Currently, energy conservation has become a global consensus, governments around the world have introduced a new energy industry are related to support policies to encourage and support the development of new energy industry, which gave birth to a staggering market share, the huge world of solar energy development as the market. According to related statistics, the global solar thermal market is rapidly growing. In the United States in 2009, total U.S. demand for solar energy grew 36%, while demand for oil grew by only 2%. Solar water heater industry is very optimistic about the prospects for the international market, more and more companies escape local corporate image, towards the international development, increase exports, expansion of overseas operations territory. In order to develop low-carbon economy, energy conservation as the main trend, under, along with China\\ s solar thermal industry\\ s rapid growth and increased competition, the domestic market getting smaller and smaller share of the cake. However, there is a huge international market for solar consumer demand, many manufacturers are targeting this vast market. Meanwhile, the domestic manufacturers of technical R & D investment, the main stay for many years China solar water heater use in low level areas and in core technology is still a wide gap between the international advanced level, and this also means that behind the huge foreign high-level market, Chinese enterprises have not yet been opened.

In 2010 at the solar thermal industry forum, the National Energy Bureau of the experts made it clear that the world\\ s solar thermal industry is now in rapid development, Europe, Africa, South America has a very large market space, Chinese enterprises should look world, to go abroad to build global system. Perhaps on the road to internationalization will be many challenges and obstacles, but from the global solar thermal industry development trends, internationalization is inevitable direction.

International road Gairuhezou?

China\\ s solar thermal companies go international is still a long way to go, and there are more problems and difficulties, mainly in the following four aspects: 1, product quality, many companies in the export of products abroad, after being returned Customer satisfaction is low; 2, technical issues, resulting in low-technology is an important reason for poor product quality, one of China\\ s current production technology, or whether it is solar thermal technology with the international level there is a gap; 3, the price problems, domestic enterprises always want to win at low prices attracted foreign consumers, so that the enterprise in terms of quality and attention to reduce the brand; 4, no brand management issues, most enterprises are OEM OEM manufacturing enterprise , the lack of independent management of the brand, can not form in the international influence.

Therefore, the honor went to domestic products abroad, whether in products, technology, brand and other aspects need considerable upgrade and long-term promotion. To dominate this trend, and only increase R & D, and gradually narrow the gap with the international solar technology, product quality and technical content by the win, or a technology leader in the future will face tremendous pressure at home and abroad enterprises. Accelerated pace in the international situation, the solar water heater industry is about to face global competition, firms reduce the number of only R & D and sales channels with those who have a chance to win advantage.

Recently, the domestic solar industry, there is a new focus on the promotion and trade platform, which is located in Tongxiang, Zhejiang new international energy market, the market as a global trading center purchasing solar products, solar water heaters will be good at home and abroad to come together, greatly strengthened the domestic solar industry exchanges and cooperation, expand foreign sales of domestic business channels.

Solar water heaters into the stagnation period of suffering

Solar water heaters the main battlefield in the rural, urban and overseas markets has been supporting form, especially in the urban market development is not smooth, a few years ago in rural areas experiencing excessive competition has been saturated, overdraft. This year, domestic solar water heater in a tough retail market stagnation.

    Number of brands in order to speed dropped 20 per month

    Solar water heaters the main battlefield in the rural, urban and overseas markets has been supporting form, especially in the urban market development is not smooth, a few years ago in rural areas experiencing excessive competition has been saturated, overdraft. This year, domestic solar water heater in a tough retail market stagnation.

    Persist in the end is victory, the question is who can stick to the last? When shuffling the end of the market is 2011, or 2012, or has not yet bottomed out?

    Faced with more than 5,000 brand once the domestic solar water heater industry, after the climax of the blowout in 2009, 2010, high callback, stagnation in 2011 entered a wait, not only the number of brands in the monthly rate of more than 20 sharp reduction, marketing and sales suffered an unexpected deserted, and even solar energy franchise dealers closed their doors, there have been a lot of situations.

    In an interview on the market, the reporter surprised to discover that "the main battlefield of solar water heaters in rural, urban and overseas markets has been supporting form, especially in the urban market development is not smooth, a few years ago in rural areas experiencing excessive competition has saturation and overdrafts. This year, domestic solar water heaters in the tough retail market stagnation. "

    Situation is bad?

    "The situation is very optimistic about the other companies do not know the situation is not better than that." Early in February, Yangzhou Lida solar Luo Cong chief engineer of communication with the correspondent, it expressed concerns about the overall trend of the market this year .

    March 16, Chang-Qing Wang, general manager of marketing, Tongji sun solar energy, told reporters, "Since the Spring Festival, the basic small retail market, sales can only go to the market daily by businesses to drive sales. Not to engage in activities, the business basically can not sell."

     Chang-Qing Wang also revealed that the previous business activities are mainly done in the town, now only village to sweep the streets, a village gradually break. Previously, do buy gifts to send Qijian Tao cutlery, knives Five-piece is very good, now get the refrigerator to buy solar air-conditioning effect is not obvious to send.

    It is understood that, due to solar water heaters are "first hit after the delivery" mode, as early as November-December period last year, many solar companies are businesses through the annual General Assembly in the form of advance payment from the business office and return the funds. Reporters learned that the Four Seasons song Mu and other large companies off-season back section near 500 million in companies and other off-season glory reimbursement reached $ 100 million, some SMEs are 2000-5000 models of the off-season back ten thousand dollars.

    However, despite collecting money, but in the end product is no longer marketable. Zhenjiang Dantu district of solar energy from the dealer said, "The town is also more than 20 years ago to sell solar energy to the rest of this year 10 not to. Since the Spring Festival, the volume of retail sales in mid-March, only four too deserted. "

    An Zhenjiang solar heaters dealers offer a set of sales data: the year 2005, sales in the four to five hundred units a year in 2009, only 200 units sold in 2010 only 40 goods. The first quarter of this year there is no sign of recovery.

    "This year s solar exhibition in Wuhan, more than 200 exhibitors, compared to last year to reduce the more than 100, which essentially reflects the current state of the solar market." A solar energy company in Shandong official pointed out that this year Even some of the show for a living exhibition of solar energy companies, business is not good to do.

    Go?

    Rural markets are no longer marketable, urban progress is slow, limited export-led overseas. Right now, for many in the rural market as the main body of the solar water heater business, how to break through the current market difficulties, it is not easy.

    It is reported that the domestic solar market in rural business enterprises accounted for up to 90%. In recent years, many companies that "the layout of the three major market" strategy clearly to return to the city market, to achieve a new round of expansion. However, the reporter learned that the return of many cities in the solar business is not successful, due to construction planning, product technology, consumer habits, enterprise resource reserves, and many other factors, many solar companies mainly in the urban business enterprises of construction orders mainly, it is difficult to obtain from the residential area of ??volume of orders. Currently, the city consumer awareness of solar water heaters generally low, also had the water leak, installation of the property caused by deep contradictions and memory problems.

    This year, the CCTV weekly quality report for the first time disclosed Haining region of the solar companies Pong brand "," cut corners "and a series of acts, a reflection of this from the" grass roots "started the industry in the development of a number of drawbacks exist. Industry with low barriers to entry, product quality is unstable, service gaps, low-price competition after another, directly reduce the overall competitiveness of the industry, but also drag a group of industry leaders to upgrade the pace.

    As early as the end of 2009, domestic solar industry has set off a wave of industrial upgrading, mainly for the establishment of modern plant, modernization of production facilities, the implementation of cross-regional plant, and thus "out of hand workshops, shoddy" industry first image. However, industry analysts, the solar industry to upgrade is a long and difficult process to get rid of roots from the plant construction industry, into the equipment and other means, to the future strengthening innovation, the implementation of differentiated restructuring, to achieve brand, size expansion, but also need more accumulation and investment. The solar thermal industry has entered a competition of comprehensive strength and endurance channel.

    Short term, Li Jun, president of Four Seasons Solar Mu song that, on the one hand to speed up the pace of expansion of urban markets, in particular, to help countries to build 10 million units of affordable housing policy opportunities to build low-carbon building low-carbon products. On the other, through product upgrades and technical means to achieve quality and service intensive rural market.

Can high-rise buildings to install

June 16, Lee reflected, she did not live in a unified high-level residential installed, the property they want to be informed when the installation does not allow unauthorized installation of solar water heaters. Residential property that residential construction in order to maintain the unity of style, the relevant departments of the high-rise buildings do not allow owners to install solar water heaters. \"Now the country attached particular importance to energy saving, how can you not allowed to install energy efficient solar water heater it?\" Ms. Lee is very confused.

Ms. Lee told reporters, her living quarters for the construction of the road a senior community, not all of the real estate community to install solar equipment. Ms. Lee had just moved in six months, due to not allow the installation of solar water heaters, so some time ago bought a Taipower water heater, but a month down the extra hundreds of dollars to tariffs particularly distressed that Ms. Lee. \"I had been using the solar water heater, although summer water consumption, but also a month with a few dollars more than usual water only, since the installation of the electric water heater, the electricity spending was up.\"

Reporters learned from the city housing construction sector, March 2010, Municipal Construction Committee and the Municipal Council by letter six departments jointly issued the \"speed Liaocheng promote the use of solar thermal systems implementation of views\", said the use of three views time, the city\\ s urban solar penetration from 20% to 50%. Comments after the implementation of urban multi-storey high-rise buildings and solar installation rate has improved significantly. Ms. Lee are living in residential construction time earlier, so the installation of solar energy is not uniform policy provisions. At the same time, said the staff, residential property owners to install solar energy to prevent the practice, and there is no legal basis, should be mainly for security reasons, so the owners can install solar on the problems and property to continue consultations.

Non-

Said solar energy, wind energy is clean energy, low-carbon life can not live without them, but solar energy was what would happen to it, really popular. This was a household word to understand. In order to understand the use of s across the province, the provincial Environment Federation and the provincial Department of Environmental Protection Education Center to prepare the joint investigation, and specific investigations by the Environment Council, the province\\ s 10 college students use the summer to complete.

Mixed community of solar water heaters

Solar water heaters and electric water heaters make a choice between the two, how would you choose? Some people say that a good solar water heater, saving electricity saving resources, but some people opposed this, after all, winter solar water heater does not seem particularly useful.

Provincial Environment Federation, the official said, some places like the use of solar water heaters, for example, in Hefei, part of the district or even be able to see into a piece of solar water heaters, and some communities are biased for solar water heaters, solar water heaters and even refused to enter the cell the installation. This allows the use of clean energy solar facing some embarrassment, people in the end is welcome to it? Select the reason for that? The reasons for rejection lie? The use of solar water heaters and what the advantages and disadvantages of it? June 21, the provincial Environment Federation and the provincial Department of Environmental Protection Education Center jointly launched the province\\ s use of solar water heaters investigation, so that one thousand students of their own usage to a large survey to find out first-hand information.

Survey will be reported to government departments

Energy conservation, low-carbon life, this really doing? Investigate and understand the usage of solar energy, may be able to see reflected conceivable picture.

Provincial Environment Federation officials told reporters that the investigation, from the province\\ s urban and rural residents to start a low-carbon living conditions, a comprehensive understanding of the application of solar water heaters in the province of the real situation, to fully grasp first-hand information, and integrated the relevant circumstances, to write a special report submitted to the government and relevant departments.

Quality enamel interior upgrades

    In recent years, more and more consumers increasingly tend to use enamel interior material of solar products, and abandoned stainless steel liner. This means that more and more popular in the enamel interior, .

    From the technical point of view, the interior is the heart of solar water heaters, and its performance affects the overall product life. As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the vast majority of products on the market uses a stainless steel liner. However, the stainless steel liner susceptible to corrosion, easy to absorb deflated, pressure defects such as poor performance has been unable to solve. The enamel interior is durable and has a pressure, anti-corrosion, anti-smoking flat, clean water and other features, has been popular in the field of electric water heaters, solar water heaters will also upgrade the liner of choice.

    From the market, the enamel interior solar market share increasing rapidly, especially in split-pressure, balcony hanging solar energy project to demonstrate superior performance of the market, but also more and more manufacturers and real estate agency\\ s attention, and thus become pressure solar project of choice. The industry believes that the future development of solar water heater industry, market pressure will become the dominant application. Stainless steel liner era is gradually during the transition to the enamel interior.

    National Cheng Kung University to replace stainless steel liner enamel interior trends

    It is reported that split pressurized, hot water system in the balcony wall of the tank has now been largely achieved enamel interior to replace stainless steel liner. In this area, enamel interior has more than 70% market share, the other is stainless steel, rotational molding liner. In 2010, Xi\\ an balcony wall of a real estate tender scene, nine solar companies to bid, of which seven companies enamel is used in light water tank. The top 50 companies in the industry, more than 80% of the companies and light tanks supporting the cooperation with the business. This fully shows that enamel interior tank has become a must-pressure tank.

    And one for non-pressure solar water tank, it seems 90% of manufacturers are using stainless steel liner, enamel interior, although the share is very low, but substantial growth every year.

    Stainless steel liner products have limitations

    As the stainless steel liner technology easy to implement, production equipment, R & D costs are lower, the market for more than 90% of the product is used in stainless steel liner. Stainless steel solar energy in the \"open\" state without electric heating, the use of better, and longer product life, which is the rapid spread of solar products to advantage. However, once installed electric heating devices, especially the use of a pressure-type operation, stainless steel liner products have significant limitations.

    Insiders said that the early solar industry technology is imperfect, there is no installation of electric heating devices, but with the maturity of technological innovation and increasing consumer demands, and now most solar water heaters installed electric heating equipment, pressure solar water heater much greater users.

    This is equivalent to have a solar water heater electric water heater function. However, the \"heating\", \"pressure to run\" and other features of the application, the stainless steel liner has appeared in the field of electric water heaters, \"corrosive\", \"water quality perishable\" problem incidents in the solar water heater is also often, problem can not address the root causes. Once Addressing the root causes, the only way is to upgrade the tank.

    The future of solar energy market must be the main battlefield of the city, which means that high-level split with the City of small solar energy will become increasingly popular in the city, split solar energy requires a certain pressure, while the cost of stainless steel more expensive, many manufacturers In order to reduce costs, make use of thin stainless steel liner, usually only 0.6 ~ 1.0mm, voltage capability down, water heater leaks more easily, directly affect the life of water heaters.

    Stainless steel liner and a maximum risk – \"weld.\" Stainless steel liner biggest risks is the \"seam\", there are two on the inner ring and a straight seam weld, the weld between the cross-junction, the junction of the stainless steel of the original ingredients were seriously damaged, and easy by corrosion of chloride ions in tap water, bring to the water pollution.

    Have the advantage of enamel interior

    In contrast, enamel interior is the high-tech products, in the thick cylinder liner surface enamel, enamel metal material, together with seamless welding technology, can bear a greater range of temperature changes, usually in the range -60 ? ~ 450 ? temperature range, to be able to withstand sudden changes in temperature. Physical characteristics, compressive, tensile, elastic, electrical insulation, non-polluting; chemical properties, acid, alkali, high temperature resistance, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.

    Industry experts say the popularity of enamel interior is split solar inevitable.

The course of development of

    As the world\\ s largest manufacturer of and consumer, China\\ s solar energy industry with annual capacity of more than 35% annually. The most traditional solar water heater is a stainless steel liner, mainly due to the reasons for the industry\\ s technology level, stainless steel liner of the defects has not been solved. According to the relevant departments test showed that the corrosion of stainless steel liner in hot water after a large number of ions harmful to human health, long used to bathing, washing vegetables, washing dishes, etc. will adversely affect users, especially on the body resistance is weak, people prone to allergies skin more obvious. With the gradual increase consumer awareness of health, with \"clean water\" performance of the water heater in the field of solar energy promotion is increasing.

    Water heater History

    When we are walking into a store counter water heater, see the \"net blue liner\", \"Titanium Liner,\" \"Kim Kyu-liner\", and other items so that consumers get confused by the water heater, you could not tell. In fact, so far, water heater tank had experienced three generations of the development process, in which the electric water heater of the development process longer, have decades of history, the solar water heater started late, only 10 years of history.

    ? The first generation of liner: zinc, copper liner

    Features: thin protective layer, no rust treatment, easy to scale, short life.

    Universal situation: basically disappeared.

    ? second generation tank: stainless steel liner

    Features: good material, not rusty, but the biggest risk is \"weld.\" There are two on the inner ring and a straight seam weld, the weld between the cross-junction, the junction of the stainless steel of the original ingredients were seriously damaged and susceptible to corrosion of chloride ions in tap water, bring to the water pollution.

    Universal conditions: electric water heaters have been represented by Haier, had a certain market, but from 2006, Haier has also eliminated the stainless steel liner, full use of enamel interior. At present, whether domestic or international market stainless steel liner is almost extinct; solar water heaters in the Mitsubishi three workers, Emperor Ming, Qinghua Sun and other companies represented. As the control period by the popularity of stainless steel liner to enhance the period of excessive enamel interior, so the stainless steel liner of the market is still large.

    ? the third generation liner: enamel interior

    Features: high-tech products, cylinder liner surface in thick enamel, metal or ceramic materials, mostly silicon compounds, together with seamless welding technology, can bear a greater range of temperature, usually -60 ~ +450 ? of temperature range, to be able to withstand sudden changes in temperature. Physical characteristics, compressive, tensile, elastic, electrical insulation, non-polluting; chemical properties, acid, alkali, high temperature, water vapor, a variety of ions can not penetrate its surface are, can not effectively ensure the quality pollution.

    Universal conditions: electric water heaters, AO Smith, an international brand with Kim Kyu-liner, Ariston titanium liner, represented the brand in the domestic interior light blue magic, blue liner Mitsubishi three represented the net work, at home and abroad occupy most of the market share; solar water heaters, to light blue magic liner, net blue Mitsubishi three workers, represented by water-based liner, the rapid development of the market and strong consumer identification with the most growth potential.

    This shows that enamel interior, electric water heater in the birth of the field is a long process. From galvanized steel liner, to the stainless steel liner, which developed into enamel interior. At present, domestic and overseas markets, enamel interior, have switched to become a mainstream product. Electric water heater solar water heater started later than some, also went through this process, now popular term by the stainless steel inner liner to the enamel transition period, and net water blue enamel interior liner technology for the solar peak representative.

    Solar technology is imperfect early development of the industry, there is no installation of electric heating devices, but with the maturity of technological innovation and consumer demands increased, most solar water heaters are now installed electric heating equipment, solar water heaters that have a water heater on the function . However, with this complementary technology to the optical, electric water heater stainless steel liner in the field of \"corrosive\", \"water quality perishable\" problem incidents in the solar water heater is also often appear, to some extent caused by the consumer questioned the entire solar industry. So, with \"clean water, health and durable\" enamel interior features full extension in the solar industry is inevitable.

    Now the vast majority of solar water heaters electric water heater has not been the product development stage, not dedicated to the development of enamel interior, water-based enamel liner technology with very few companies. Relative to the normal enamel interior, net blue water-based enamel liner material used is high-grade enamel, enamel by two 900 ? high temperature baking, the bottom plate of mutual penetration of the glaze and the integration of steel and water is not guaranteed will contact, can effectively eliminate the ordinary enamel interior was often blistering, peeling, uneven enamel-plated case, the surface enamel can prevent oil, at the end of the glaze can prevent rust.

maintenance man eye disability caused by an explosion

    Solar water heaters are to check, the result was an explosion, Fuyang City, Mo was the peak of maintenance man\\ s eyes suddenly bled. To this end, Mo was the peak water heater will Nantong Co., Ltd. and Koyo distributor of the product to court. Recently, the Funan County\\ s Court of Nantong solar water heater Co., Ltd was the peak of compensation for the loss of Mo 20004 thousand.

    May 16, 2010 1:00 pm, maintenance man Mo peak was home to the Funan Zhu Zhaizhen Xiaomou maintenance of solar energy. User Xiaomou said his family purchased in the solar July 28, 2008, May 10, 2010 there have been leaks, put no water is. \"Maintenance man to repair the afternoon, go up soon, do not know why, this solar explosion.\" According to its introduction, the explosion sound was great.

    Mo was the peak, said he boarded the user Xiaomou home after the roof, began to examine solar energy. Check the water out of the water in the process, the water normally found in water, it then looks at the water hole and the host connector is a problem. To check, MO was the peak just to the host barrel water hole eyes leaned on an feeling the heat emitted, and then feeling a sharp pain in his right eye, then immediately heard a loud noise, sounds great. The original solar energy exploded from the host Mo were front lid flying overhead.

    Fuyang City Hospital initially diagnosed as right eye blunt trauma, hyphema, corneal injury, traumatic mydriasis, lens subluxation, vitreous hemorrhage. Subsequently, Fuyang City, MO was the peak at the hospital recommended EENT Hospital of Fudan University for further treatment. The Ins and Outs of Mo peak was 20,000 yuan spent on medical expenses.

    The inspection after that, the solar water tank explosion, a damaged, pop out the other end of the cover. Koyo Solar\\ s commitment to the product brochure liner thickness of 0.5 mm or more, but after the actual measurement, the incident solar liner thickness of only 0.24 mm, significantly lower than the thickness of the product promised. At the same time, Mo peaks were also found, the incident solar energy is no safety valve, and solar energy are the same brand around the valve.

    At the same time, last August, Fuyang City, Mo fair judicial identification of significant peaks on the degree of disability were identified, concluded that the Mo peak was caused by blunt trauma right eye blind four or more, are eight disabled.

    In the case of multi-party rights unsuccessful, Mo was the peak will Nantong Co., Ltd. and Koyo water heater distributor of the product to court.

    Funan court, after hearing that the incident solar liner thickness of only 0.24MM, significantly lower than the thickness of the product promised. And compared with the same type of product, lack of safety valve above the tank with defects. Earlier this year\\ s Court of Nantong solar water heater Co., Ltd was the peak of compensation for the loss of Mo 20004 thousand.

    Mo was the peak that, since the thickness of inner commitment to the product, why not even the actual thickness of the product are not promised half? Mo was the peak that will continue to appeal.
