Build on the progress of
Safety, energy conservation, environmental, economic, itself several advantages. Especially with the auxiliary heating function of solar water heaters, solar-based it, supplemented by electric energy use, make use of solar water heaters can be 24x7x365.
Solar water heater, the solar energy into heat energy, heating the water from low temperature to high temperature, to meet people in life, the production of hot water use. By collector solar water heater, storage tanks and associated annexes, to convert solar energy into heat energy mainly depend on tube. Affected by sunlight collector surface temperature is high, the back sun tube surface temperature is low, and pipe the water temperature response arises, using the principle of water floating in cold water sink, so that water will reach the required micro-circulation of hot water.
Safety, energy conservation, environmental, economic, solar water heater itself several advantages. Especially with the auxiliary heating function of solar water heaters, solar-based it, supplemented by electric energy use, make use of solar water heaters can be 24x7x365.
Results of application of solar water heater is solar energy a major industry in its environmental protection, safety, energy, health, etc., quickly won the favor of consumers, China, is an energy-consuming countries, accounted for about a year to the national energy consumption total consumption of 1 / 3, while the country\\ s total energy consumption, 1 / 3 from the building energy consumption. \"To the roof to energy\", solar water heater is to absorb the sun\\ s radiant heat, heat cold water available to people in their lives, energy-saving equipment used in production.
Solar water heater in accordance with the annual average temperature 15.7 ?, the annual sunshine time 2014 hours, the total annual global solar radiation is 111.59 kcal / square meter, if the collector area of ??2 square meters, the annual absorption of solar radiation energy of 9.37 × 106 kJ, according to the calculation of water temperature 35 ? (base temperature 10 ?), throughout the year to provide domestic hot water (45 ?) 53.5 tons per person per bath with hot water about 50 kg, then the full year wash 1070 times, 2.93 times the average daily wash.
China\\ s annual production capacity of solar water heaters in Europe two times, four times in North America, has become the world\\ s largest producer and largest solar water heater solar water heater market, and is still at an annual rate of 20% -30% increase. But the Chinese manufacturer of solar water heaters more than 5,000, in addition to Sang Le, Huang Ming, Qinghua Sun, Hua Yang, Sun Yu, Li Norit in 10 national brands for quality, excellent service, high-profile outside the market, industry, there are a lot of brand-name companies are numerous and unorganized, this situation is not conducive to long-term development of the industry, which requires government departments to regulate and strengthen regulatory guidance. Although the market situation is not satisfactory, but the market outlook remains bullish. With the national economy and people\\ s living standard continues to improve, residents of the home indoor growing demand for hot water, solar water heater market, China has great potential,
But now, in our family the use of solar water heaters in the South is stronger than the northern, rural and strong in the city, further restricting the promotion of solar water heaters, there are many factors.
First, since the requirements for the installation of solar water heater is relatively high, city high-rise buildings are capable of supporting the installation of a solar energy business \"into the city,\" the key factor. As the developers did not take into account the construction of solar water heater installation, use, making the top floor residents use solar water heaters are extremely limited. Cities involved in the investigation of solar water heater users, only 7.4% of high-rise residents. Most of the remaining 10 floors below the lower floor or cottage residents. There are some residential property to develop \"local policies\", determined not to allow residents to install solar water heaters.
In addition, the government paid insufficient attention. At present, encourage and promote solar water heaters, including various types of energy facilities, including a number of policies and regulations, but more by the ministries or local governments, systematic, mandatory poor. Incentives to implement policy, not many. Such as the Beijing Municipal Development and Reform Commission issued the subsidy policy, new and existing buildings to add various types of solar water heater subsidy per square meter of collector 200, the intensity is indeed very high. However, the survey shows that consumers do not use solar energy to understand this policy and only 6.92%, knowing that accounted for 19.23%, do not know and do not know accounted for 73.84%.
Interested because they do not understand is not an important reason for interest is not directly see the benefits. In fact, 92.43% of people want the money direct state subsidies to the buyers, 83.91% of people said that if given the appropriate state subsidies, are willing to change their own water heater solar water heater. Without subsidies, it is willing to replace the solar water heater and only 25.77%. It seems, that subsidy is not enough light, but also the people by way of subsidies approved.
How to break into the city\\ s solar energy business dilemma? Cheng has become nowadays the problem to be solved.
Right now, the giants have announced a number of solar water heater to enter the urban market, and have to pay close attention to technological innovation and industrial upgrading.
Solar water heater industry is currently in a dilemma situation, the brand of solar energy companies in order to take the path of urban development, can take a step back, and building integrated solar products to combine the business of solar energy products and technology, real estate for construction and installation , the two sides to jointly as the city\\ s low-carbon, green contribution to the development, the parties also will not spend too much and a big headache. It is understood that, with local governments to force installation of the promulgation and implementation of policies, some cities have started from the user-installed, go to \"implant\" estate planning period.
If the solar water heater can break through the storm into the city to proceed smoothly, then the solar energy business through the industry is likely to be re-shuffle, a new and stable pattern of industry change. To enter the urban market, even if it is solar water heater products and building a simple integration, without a support of solar energy technology and power companies are difficult to develop. Because the technical requirements of city building products is high, small businesses can not obtain the advantages of the product; In addition, large capital investment, market development is difficult, the market has not scale, which may be preventing small and medium enterprises into the city-name element.
An industry veteran analysts believe that competition for development and development needs of survival of the fittest, solar water heater industry status quo is an inevitable stage in the development process, companies have to keep the scientific and technological innovation, the core technology in order to survive the winter, to survive. With the development of building integrated solar energy and the formation of the competitive situation of rural markets, the pattern of solar water heater industry increasingly clear. In the solar water heater, solar companies will divide into two categories: one is to survive the fierce competition by small and medium enterprises in the rural market; the other is expanding the field of building integrated solar energy, go the city route brands.

At the recent \"Seventh International Green Building and Energy Conference,\" Housing and Urban vice minister said so.
\"Second five\" government promised to build 36 million units of affordable housing, even if only half of the installation of solar hot water system, calculated according to each 3000 yuan, 54 billion yuan can also be leveraging the market. This annual sales sixty-seven ten billion scale solar thermal industry in China is concerned, once added a little half-equivalent to China\\ s market.
Start a new market to be 50 billion
Prior to this, the Ministry of Housing and Urban have been repeatedly raised, must take the protection of low-cost housing built in energy, water, land, and green building materials, large-scale promotion of solar and other renewable energy applications in buildings , boosting the development of green building.
Ministry of housing construction in accordance with the requirements of the country this year to build 10 million units of affordable housing, will invest more than 1.3 trillion yuan, the national real estate investment reached 20%. Qiu said, \"five\" during the new 36 million affordable housing units, will be the first to become \"energy-saving house.\"
Local governments are to act quickly, there are statistics that currently there were 20 provinces (cities, districts) and 80 cities issued a mandatory installation of solar energy policies and incentives, requiring new buildings to install qualified s.
Beijing issued the \"Beijing low-rent housing, affordable housing and limited to two rooms Construction Technology Guide\" is also mentioned affordable housing and low-rent housing should be using solar hot water systems, and priority use of concentrated solar hot water system. Limited to two rooms to promote the use of solar hot water system.
Jiangsu provincial government introduced the \"speed up the construction of affordable housing project view\" to provide from 2011, around the new low-cost housing, public rental housing shall be by country and Jiangsu provinces design and construction of residential building energy efficiency standards, to guide and encourage the protection of housing to create green building.
Housing and Construction Office, Jiangsu Province, such as the three, said Wang, deputy inspector, building energy efficiency compared to standard housing, in line with one-star green building rating standard housing, the cost per square meter higher than the cost of only $ 50, relatively easy to achieve.
As the earliest mandatory green building standards for the protection of housing the city of Shenzhen in 2010 to launch the first national green building standards by the construction of 10,000 units of affordable housing communities.
In October, as the Shenzhen Guangming New District, the local Department of Housing and build a national green building demonstration area is to start construction. Shenzhen request, from December 1, 2010, the new affordable housing must be fully installed solar water heating systems. The next five years, Shenzhen will arrange 240,000 units of affordable housing construction, all construction by the green building standards.

Third Age era of intelligent
absorption rate is no longer a problem, the difficulty is how low the temperature in the outdoor environment to save lives from the heat of to improve energy efficiency.
If more than ten years ago, solar water heaters just to enter the consumer\\ s perspective, when you buy a water heater, consider perhaps this is called \"solar energy\" thing is really hot in the sun arising under it? How hot the water? With us it is really hot water bath? At this time, solar water heaters \"endothermic\" is the first factor we consider.
Time to transition to after 2006, when the number of solar manufacturers learned from the market, solar heat absorption rate is no longer a problem, how difficult is the low temperature preservation of outdoor living environment of heat from solar water heaters to improve energy use rate. Since then, the sun, rain, \"Paul Wall\" as the representative of the name of \"thermal protection\" technology of the concept of product emerged. \"Heat protection\" instead of \"endothermic\" as the consumer purchase criteria.
Today, the face of solar water heaters on the market a myriad of concepts and products, you will what to choose?
Soymilk, food machine, rice cooker and other small kitchen appliances and the emergence of replacement, so you do not have to experience the traditional manual, you can enjoy a variety of gourmet cooking, whisk, peel garlic and other small objects appear more is saved from the details of your energy;
Men wear shirts appeared in PDS expert knowledge of intelligence, from design to production, to help you analyze your body type best suited to a variety of lines and cut ratio, and different designs for different occasions, quantitative production, last seen in clothing is naturally fit and desirable;
Intelligent home has become a mature modern society, philosophy, and into the homes of ordinary people, such as in your home to achieve high-definition video sharing, intelligent lighting control, electrical automation, home security monitoring, etc., the use of modern Internet and things networking technology, provides a great convenience for life;
Now look at the travel tools, information technology, control of the subway, motor car, time accurate, clear routes, subway, bus, you just gently swipe the card, eliminating the need to prepare coins for private car is equipped with intelligent navigation, GPS positioning, but is highly intelligent application of information technology.
Above, that we are now in daily life clothing, housing some of the scenes footage, home entertainment, whether you, or go work, go shopping or using the Internet platform for shopping, you either exposure to shopping malls, hotels, parks or , playgrounds, a variety of intelligent control system has been everywhere around you, you have intelligent wave flooded. If you do not operate a variety of intelligent control system terminal, do not understand the simple identification sign, no doubt, you have \"OUT\", keep up the pace of the times, and in life do not facilitate the emergence of various.
Solar thermal industry, although most contemporary green energy trend of the fashion industry, but also the birth time is not long, technical originator threshold is not high, grass-roots industry, initially with a few pieces of pipe, a water tank combination, they produced a solar water heater so kinds of classes for people bathing appliances. It is like home appliances, because it does not run the operation and use of electricity, but it along with other home appliances for us to create a more beautiful, comfortable living environment, a necessity of modern family life.
With modern appliances operate more convenient, more perfect functions, we can not ask for a solar water heater with \"intelligent\" reform, has brought us more comfortable and convenient family bath life? This has become the desire of many consumers – intelligent bath.
Ideal for intelligent bath, each consumer has his own ideas: Some people want solar water heater to the tank water level and water temperature according to the number of Sheung Shui to automatically, eliminating the trouble and inaccurate manual

Jiaxing industry pushed to the cusp
From the development of solar water heater industry frenzy to overcapacity warning, 40% of products in winter regardless of use, coupled with the quality of the door Haining, industry face the credit crisis, has stimulated successive \"late spring\", the market took a downward channel, so the market cleanse swept China, Jiaxing Solar pushed to the cusp.
But this wave of market cleansing also at shallow, only a small workshop unscrupulous counterfeiting, to give small businesses a preliminary fight and curb, but also hit the production of solar Haining reputation.
However, the next off-season market access, small and medium private enterprises in Zhejiang have faced \"money shortage\", \"power shortage\", \"out\", \"labor shortage\", \"shortage cost\" multiple extrusion, solar energy is also affected SMEs will be more tough days.
Especially the second half of the new national standard, mandatory thermal efficiency standards for the introduction of limited value, will wash away into the depth of the market, the real shuffle storm to come. So, how solar energy is not small and medium enterprises out of business? Recently, Jiaxing Solar Energy Society General Xu Zhu Ling told reporters to the small solar companies out of a medicine: the transformation and upgrading in order to rise from the ashes.
First, turn the concept of change of mind. Can no longer profit-oriented, impetuous frenzy, blindly follow the trend. Business to be profitable natural, but arise in the future sale, which is the bottom line, is conscience. Corporate positioning is critical, SMEs must be good products, you can do for the big brands supporting large enterprises, they can not act or niche Plough, to create regional brand as a market supplement, the cost of management and channels to play with a flat to the price advantage, rather than go to follow the trend of poor quality cheap black sheep.
Second, the quality can not stand without a license. Completely abandon the mark, please buy the Chi endorsement impetuous self-styled brand, devote themselves to do a good job quality. Jerry is not only a moral bottom line, how to make products to meet consumer demand to rely on technology, \"thermal efficiency limit value\" has become a mandatory standard, the day heat gain and heat loss be useful is an important indicator, one or three differ significantly from in terms of sales volume, price, how do four methods:
1, matching high-quality vacuum tube. Good solar absorption rate of 0.92-.094, hemispherical reflectance of only 0.04-0.06, and used a rough upper tube, the poor do? Less than the current national standard 0.86 and 0.08, but not less than the cost of purchasing \"black pipe.\"
2, the temperature may rise, there is water right capacity and collector area ratio, which in theory there is a formula to follow, can guide the design and production. We are not selling output hot water pipes, and if you do not have this ability, there is no self-test equipment, advise you to change the behavior is good.
3, polyurethane insulation commonly used high-pressure perfusion, at least 35 density, thermal conductivity less than 0.02, closed-cell rate of at least 92 different regions in the visual thickness of 4-6 between the head but also to maintain the same thickness at both ends, can not have gaps because here the fastest heat.
4, optional high-quality seals. Can also be used under the exhaust points. Of course, pipe insulation measures are equally important. After the introduction of mandatory standards, certainly there will be supervision the case, can not have chances, censorship is a good, high-volume sale is bad, since it is self-deceived, will still be eliminated.
Third, there is no condition to do the transformation and upgrading of the upgrade. In order to shift profit model. Look beyond current market decline is a stage, the domestic rural areas, small towns solar penetration is less than 10%, still far from saturation, is now a good time to upgrade the product. Intelligent, all-weather, healthy water is to upgrade the general direction. Control instruments is the confusion caused by electrode sensors, digital pressure type can be used as its test signal frequency current is less than 120 less than 50, will not scale, less failure rate and longevity, electric auxiliary heating to adopt energy-efficient, water tank can be less able to inhibit bacterial fouling liner, of course, not equipped with high-quality pipe insulation measures to avoid the lightning systems and equipment, convenient, safe, easy to use in winter, consumer satisfaction, and business in order to have the right to life.
Fourth, the conditions to transition. Market is a multi-layered, diverse, urban and rural water heating project market, the city\\ s building-integrated markets, industrial and agricultural markets in temperature, high temperature power generation market, are 1000000000000000 huge market, you can research, according to conditions to choose your resources or reserves to this technical transformation, such as tablet coating, flat-plate collector, all kinds of water tanks, air heaters, air collectors, solar boilers, combined heat and power facilities, etc., these markets just started, much to offer.

market is still vast
Over the past few years, solar water heater industry experienced a long period and then experienced a severe outbreak of the reshuffle, the industry\\ s situation has become more severe. However, its overall position, the shuffling of solar water heater market, or played a certain role, but also for medium-sized enterprises market handed in a satisfactory answer. It is said that a number of enterprises over the past year is a year off, but also a number of companies struggling to year, or some companies come to an end of the year, summed up as \"ten thousand happy Wanjia Chou!\"
The current state of development of solar water heater industry competition are: the brand through the high concentration, product homogeneity, price wars continue to unfold, a large hematemesis promotional activities. But everything has double-sided nature of these crises are accompanied by so many opportunities to solve the immediate difficulties as long as, future profits will follow.
Intensified price war in the industry even when heated, then the industry\\ s most pressing is the possibility of an innovative ability to lead the industry toward blue ocean business, then the general business how to achieve this it? Then differentiation strategy will play a leading role in the so-called difference is from the brand to the products, features, and so completely innovative product differentiation that is out of business innovation, R & D product features, characteristics, quality and other unique characteristics to guide the industry from R & D price war to healthy competition on the road, so that more technology-oriented, functional, technical and multi-purpose high-end features such as practical, the price is secondary to the main product so that consumers can really have no experience to value enjoyment, a sense of high technology products more quality of life is important, in the mind of the consumer are different from the image. Increase product sales and market share, competitors completely different direction to the customers to enjoy science and technology, sales, or against competitors. The implementation of differentiation strategy is to find differences in key focus of differentiation may exist in the products, services, brands and creating value in the whole process.
Through product and process innovation, product value to reposition to avoid along the way with the competitors compete with the same situation, as no doubt for the enterprise\\ s own self-destruction. New ideas, performance, technology, marketing, and other points of interest and demand and selling price is totally out of competitive strategy.
Consumers of our products, we at the same value in addition to the products and functions, we should be unlimited service, we need to buy our products so that consumers feel is the right choice of self-honor and sense of accomplishment, if consumers buy our products are mundane, or general, etc., which shows that our service is a failure because we do not only products and services, but also for the consumers of our products and services to meet the spirit. Service Cup is the soul of our brand. Price competition, it forces companies to reduce costs. The long run the economy more efficient. But excessive price competition will lead to business benefits decline. So. Companies should adopt strategies to avoid the vicious place.
Companies must have their own core competencies and core technologies. In order to enable enterprises to gain a lasting advantage. Price competition is only the initial stage of market competition, quality, service, innovation is the enterprise more effective to victory, half a beat fast a company\\ s core technology is to avoid price points and enhance the brand is a company with sales of the final choice, the difference between marketing oriented, so that the core of technical marketing.
Price war is a short-term sales volume tool, can be the purpose of sale is the business to profitability, because some companies quick success of the marketing practices led to lower product value and cost-effective complete a sale is the product into money in the process often referred to as sales, However, the sale must take advantage of 21st century marketing techniques to sell rather than a price war, then what is marketing? There is every step of marketing strategy, a strategy and a strategy, there are ideas and vision to put products into money in the process is called marketing. In the solar industry manufacturers such extremely busy today, certainly there are many companies involved in price wars in order to gain greater market share will reduce production costs in the selection of timber down enough effort, the greatest harm to consumers and our the solar energy industry in a whole new brand. So we need to implement very fast and a half shot of technical marketing, energy marketing, away from the price war, technology and practical function in the upper and lower foot, allow consumers to enjoy more high-quality high-tech clean energy solar energy.
Solar water heater industry promotional activities abound. For promotional items from various manufacturers to pull out all the stops to Yuba kitchen pots and pans, towels, denim, Winston was, space cup to the small home appliances, rice cooker with a corporate logo of a wide variety of everything a small umbrella . So what kind of solar water heaters use gifts as promotional items do? First, that the role of promotional products under: 1, to stimulate the desire to buy cheap used to stimulate people to buy petty desire to promote the transaction into; 2, to promote business products and enhance corporate reputation, corporate image, to guide repeat purchase or recommendation.
So the solar industry to choose promotional items that can really achieve the objective which? The following promotional materials say that the next solar purchase a few principles.
First: novelty; solar promotional items must be novel, can not choose the supermarket or street stall can buy the product, it will give the customer feel new. Enhance the sense of the value of solar promotional items.
Second: practicality; solar promotional materials selection must consider the practicality of the product, gave $ 2.5 specific housewife bottle of Coke, it is better to give her $ 2 a bottle of soy sauce, young men who gave five dollars a bottle seasoning is better to send a bottle of Coke $ 2.5.
Third: industry relevance; solar water heater itself is a promotion of a low-carbon energy products, if the choice of promotional products is energy-consuming products and product ideas contrary to it, so I chose a low-carbon industry-related environmental or solar gift gift solar water heater industry is a good choice.
At present, many companies feel the situation is less clear, questioning, tangled and confused, weird smells, the dealer and the team have vowed to show some appearance, business owners tired, or even give up a lot of re-thinking operators green in this environmentally friendly development of the industry.
Market competition in today\\ s industry is inevitable, and only in the fierce competition in the enterprise in order to fully demonstrate their overall strength and their own values. From this we can see, the solar industry is to keep the pace of development forward.

Horses eagerly look forward to the new
After years of painstaking research, Suizhou a college physics teacher Lin Xuejun received a total of four national invention patent, but suffer from lack of funds, poor information, resulting in several patents shelved, can not be transferred, so that he distressed endless.
This year is the 53-year-old Lin Xuejun Suizhou Vocational and Technical College physics teacher. His four patents, all on . Among them, the direct thermal solar water heater project, the most technologically mature, he has produced a prototype, in their own use more than a year, the results were good.
After the Cultural Revolution as the first batch of top students admitted to the University Department of Physics, Lin Xuejun been particularly fond of machinery and the like, usually likes to use their expertise, engage in some electrical improvements and other aspects of testing.
One day in May 2007, he was walking on the balcony, suddenly found their own on the water heater in the construction is unreasonable: condenser panels absorb light energy is not sufficient, there is light leakage. So he decided to design a maximum absorption of light energy, and affordable new water heater to the benefit of the public.
Went ahead, Lin Xuejun got materials, the family as a factory, buried his trial began. Even lying in bed at night, with new ideas, he would immediately stand up out of bed, began a trial.
In May 2008, his \"solar concentrator device\" technical success, and won the State Intellectual Property Office patents. This invention, the biggest advantage is that the heat pipe solar water heater to maximize the absorption into the heat, so that the heater faster water heating, the temperature higher. However, this invention also has shortcomings: the sun reflector laser tube heater receiving area by the thickness of the restrictions. So he decided to technical improvements.
After nearly a year of trial, he will gradually stretch the transformation into a parabolic reflector surface of the reflective tube type, to solve the drawbacks. In February 2009, his second invention \"to follow the solar laser device\" to obtain a national patent. But soon he found that the use of this technology to produce solar water heater costs may be higher, so once again improved.
May 2009, his \"axis bearing solar water heater\" technology to obtain a national patent. Relative to the existing water heater, the use of this technology to produce more absorption of solar water heaters, heat and fast, good thermal insulation, and low cost.
However, solar water heaters in the shaft bearing should take place in many places, Lin Xuejun decided to invent a small area, convenient to place the water heater. In May 2010, his \"direct thermal solar water heater\" technology to obtain a national patent.
Lin Xuejun said the direct thermal solar water heater simple structure, the water tanks, insulation, light board composed of three parts, with the existing water heater, install more water, low-cost, small footprint, both flat, but also can be hung on the wall.
Yesterday, the reporter Lin Xuejun lived to see him on the roof of the production of 4 water heaters have their own characteristics. Currently, Lin Xuejun family are using a direct heat to produce their own solar water heater, \"very good, I am most optimistic about the technology.\"
But good technology is not easy to translate into productivity. Lin Xuejun told reporters over the years, to these inventions, he has spent 3 million yuan. To promote the technology, he four links, multi-promotion, can be thwarted at every turn, no one wants to transform his skills. Holding advanced technology, but not into, so he took a sense of loss and embarrassment.
\"I just hope that these technologies can benefit the people, as to how much money is not important to me personally.\" Lin Xuejun want to have \"horses\" phase of his technique, as soon as possible achievements.

Implementation of energy efficiency rating of solar water heaters save controversy
And home appliances products, the industry\\ s energy efficiency rating of solar water heater has been the existence of different views. There was a call as soon as possible, was not impressed, and even said that energy efficiency rating \"useless.\"
In the \"domestic efficiency of limited value and energy efficiency rating\" has come to declare stage, this debate is still very intense.
Industry experts point out that there are different views on the standards is a good thing, to a certain extent, in terms of the industry will play a role in promoting healthy development. The relevant authorities should listen to the sounds, and co-ordination. This is the standard implementation of the greatest significance.
Pros: help upgrading the energy efficiency rating
For the most important areas of s – one of the enterprises in Shandong Province, the energy efficiency rating standard is to promote industrial upgrading of necessity. New Energy Co., Ltd. Shandong Power Norit Reaffirming that the civilizational, general manager, said the implementation of energy-efficiency labeling for the solar industry has undoubtedly established a rule, can further regulate the market, and promote orderly competition in the solar industry; For consumers, the choice of products with a clear frame of reference, which will help promote the solar industry to further enhance the overall level. In Europe, energy efficiency label has become a substantial technical barriers, China is a solar water heater manufacturing and exporting countries, to enable energy-efficiency labeling of products to enhance the development of solar technology level, the overall quality, and expansion of exports and so has a positive role in promoting.
Solar Energy Technology Co., Ltd. Shandong Ford Division product manager Wang Dehua, also holds the same view, he believes that once the energy-efficiency labeling of approved national standard policy really down, will enhance the brand awareness of consumers play an active role. Because consumers do not understand the case of solar energy products, only preferred brands, guaranteed not to buy the wrong things. Then the energy efficiency label will serve as the national standard identified the most intuitive, value-added products and brands to enhance the degree of product play a positive role in promoting sales.
In addition, some companies argued that the implementation of energy efficiency level will be the development of enterprises play a crucial role. American and Solar Energy Industry Co., Zhejiang official said, energy efficiency labeling does not necessarily lead the industry to enforce the final shuffle, but to get some energy-efficiency labeling certification of enterprises, promotion of energy-efficiency labeling can quickly dominate the market, get some market share. To be sure, solar water heaters, energy-efficiency labeling will eliminate part of the implementation of energy efficiency products with low levels. Temple officials said solar energy, energy efficiency labeling serve two purposes, both to promote the industry technology standards, but also for companies to secure some of the policies or subsidies, paving the way.
Cons: meaningful and will increase the cost
Although the implementation of energy efficiency rating standards will have a major impact on the industry status quo, but some business representatives believe that the product characteristics and the solar water heater industry status does not apply to this standard.
Anhui Wang, CEO of Eagle call say so, energy efficiency label is in imitation of the appliance industry, meaning not great. Solar energy itself is the product, the original intention to establish energy-efficiency labeling may accelerate the development of the industry, but does not exclude some special consideration. First, the ratio of solar energy efficiency does not have a unified conclusion, how to identify a problem, so the logo can contribute to energy efficiency is unlikely. Second, China has a distinct regional differences, and a solar on the Northeast, Tibet, and Anhui three places, the temperature difference determines the performance of solar energy, so the energy efficiency label should consider how the uniform is a problem. Finally, another point of view, energy efficiency labeling in air conditioners, refrigerators and other household appliances industry, the role is not large, the current consumer awareness of energy efficiency is still very low, it still dominates the consumer price.
Beijing Golden Sun Sang Po, general manager of New Energy Technology Co., Ltd. Li Zhang believes that management should give more consideration to how to improve the technology content of , not to turn the focus on energy efficiency, thermal efficiency and other concepts. He said the national research institutes and other institutions should be joint ventures, to the flourishing of solar engineering solutions introduce some criteria. For example, building integrated product specifications, pressure system, the system overheating and other issues to be introduced norms. The establishment of urban architecture evaluation criteria is the answer.
Solar Energy Co., Ltd. Shandong Lok Sang responsible person that the final draft for approval long after the experts argued, however, the smooth implementation of the final, this is hard to say, after all, its mixed industry, especially the \"corporate self- location \"in this way likely to cause data distortion.
Other practitioners said that standards are too general, and not linked to actual production, giving a feeling of not practical. Many solar water heaters in the current technology, components, standards-based water projects did not develop and improve the situation, the rush to promote solar energy efficiency standards, a bit too hasty.
In addition, some business representatives believe that the implementation of solar water heater energy efficiency label is bound to increase the product cost, for those who have reached the standard of products, as long as the subsidy can be identified, but for those who do not meet the standards of the companies need to replace the parts, This cost is bound to surge, a heavy burden to the enterprise, resulting in a number of small and medium enterprises products prices.

Pump hot water with the installation of
Living in the attic of the user, because users of solar water tank with tap water level difference is very small, not enough water pressure, water quality, and can not meet user requirements, in this case, it is necessary to use hot water pump to provide hot water. The method is suitable for small water pressure, need to boost the situation.
Living in the attic of the user, because users of solar water tank with tap water level difference is very small, not enough water pressure, water quality, and can not meet user requirements, in this case, it is necessary to use hot water pump to provide hot water. The method is suitable for small water pressure, need to boost the situation.
When the lower solar installation position or the top floor of the user, if the water level in the tank water taps than 5 meters above the outlet, the water pressure is not to 0.5 kg, the user will feel very slow water flow, which is heating the water poor quality. Change the way is to add a booster pump, so that water pressure can be up to 2 kg, significantly improved the quality of water.
Many different types of booster pump, but at higher temperatures, performance, high quality requirements. Relatively good results Ville Germany, Denmark, Grundfos, South Korea, Hanjin, etc., such as Shanghai China Xishan, Guangzhou and other lower quality format too, but can also be used. Hot water supply pump is automatic, once the user opens hot water tap, water pump is automatically turned on, pressurized water supply. These two types of pumps, water flow and pressure on open, its principles will be described in later chapters. Shown in Figure 4-3-6.
Figure 4-3-6 with hot water pump schematic (flow switch)
Principles of explanation: When the user opens the hot water tap, the down the pipe in the shed, start the water flow switch 5, the flow switch connected to the pump power, pump water to the front of the user Department. The most commonly used pumps in two forms: swing-type water flow switch and pressure switch, the specific principles in detail in later chapters. Using pressure-type solar water pump can be placed in the program lower than the position of the tap water, such as the grass in the upper villa.
