Temple of not meeting board box

[REVIEW] \"just buy a new installed, Guo Dabo will be found outside the box and the heater body is not supporting. Is the second mobile phone or install the wrong box?\" Guo Dabo doubt endless. Solar water heater models and packaging are not matching.

      Just buy a new solar water heater installed, Guo Dabo will be found, the water heater outside the box and the body is not supporting. Is the second mobile phone or install the wrong box? Guo Dabo doubt endless.

Solar water heater models and the box is not complete

May this year, Guo Dabo located in Zhejiang Province, home appliances market Qiutao North electrical firm in the second floor of Xinyu, spent 2600 yuan to buy the S & P 737 one-day series of solar water heaters.

Bought this heater after repeated urging store Guo Dabo sent to install, but no other arrangement has been said time. Until the morning of June 27, water heater installers to install the door only.

Installation, installers told Guo Dabo, some parts need to buy their own, do not buy it can not properly installed. So, Guo Dabo attend to check the water heater, on a hurried out to buy accessories. When he came back bought accessories, water heater has been installed in place almost.

\"As the installation when the off-site, I have not carefully checked water heater the next day, I order water heater in the box, I found the base stand still, there\\ s no installation. So I went to the roof to check the about water heaters, but to see a lot of problems. \"

Guo Dabo said that he found the surface of the water heater tank and frame box with multiple stains and surface scratches, water heater installation was not in place, easy to shake. Most difficult to accept that he is not packing water heater Temple 737 series, but another model.

\"In other words, water heaters and water heaters are actually on the box is not on, I suspect, this is a secondary water heater, is likely to be the prototype and they gave me a box to send out just broke, do not Bluff ? \"

Business for the apology extended warranty and gift

June 29, Guo Dabo related electrical firm to reflect their own doubts.

\"I bought the shop\\ s proprietress Ms. Sun also, but not 29, the day Ms. Sun, the store\\ s staff said he did not understand the situation, could not handle the matter, after which I will call Ms. Sun, She said that installation can be problematic, but the product is certainly qualified. The problem is that I was buying a new water heater, and now I get hold of even the boxes are not on, and that reasonable? \"Guo Dabo requirements Xinyu electrical firm to give him for a new water heater, and install in place.

Requirements for Guo Dabo, the electrical firm boss Ms. Sun explained that she just Temple, a distributor of water heaters, water heaters were installed to Guo Dabo workers she sent on a distributor. Cargo is sent directly from the dealer over the past, so she did not know the situation. In the end is not used, but also need to go through verification.

Why is it difficult to enter the residential area?

[REVIEW] \"Now the community are promoting low-carbon life, why install a solar water heater is it so hard?\" Recently, high-tech zones Riverfront Village area reflects the very fact that her district where the property owners to install prohibited, some owners can only \"hope Yang disappointed.\"

     \"Now the community are promoting low-carbon life, why install a solar water heater is it so hard?\" Recently, high-tech zones Riverfront Village area reflects the very fact that her district where the property owners to install solar water heaters prohibited, some property owners only. \" Wang Yang disappointed. \"

     The survey found that a number of property services in the district in the city, and the very fact that a few owners have the same experience. And for all the worry, the property of the \"ban\" a \"solar\" into some of the area is difficult to be crossed a threshold.

     Embarrassment: \"solar energy\" have been shut out

     The very fact that, since the delivery of Riverfront Village district has banned property owners in the roof to install solar water heaters, ground floor, the body that affect the appearance. The very fact that the use of environmentally friendly solar energy, promoted by the state, property owners should not be reasons not to install.

     See that the district is basically 7-storey residential building, not a solar water heater. \"Want to install check, can not let the property.\" Owners of them are said his family has been using the power of 2000 watts of electric water heater, a month to produce a lot of electricity. \"Solar energy is convenient not to waste resources, which point bad?\" Cao owners master the practice of the property also said they did not understand.

     Then interviewed a number of residential property services, found that the \"solar water heater\" shut out of a few. Oil off a building in the Town district, New Petroleum home district, hospital district have on the owners of Imperial reflects the property to \"aesthetic impact\" as an excuse, either roof or wall-mounted type of solar water heaters, are prohibiting the installation. Moreover, the already installed \"solar\" and also forced removal.

     Property: \"solar\" impact on safety and aesthetic

     As to the refusal \"solar\" reasons related to residential property have the same concerns: After installation, the top floor of the owners caused by leaking home country?

     Riverside Village, a residential property company official said, the district completed earlier, developers do not design the building body reserve base for the solar water heater and pipes. If the number of owners to install solar on the roof, the roof waterproofing can not afford the weight due to the destruction of home owners could lead to leaking roof, giving rise to disputes. Wall-wall installation in the \"solar\", will affect the layout of the building body beautiful, is prohibited, and these regulations in the residential property services in all relevant requirements.

     High-tech Park District property, Tsinghua person in charge of the installation of solar really inexpensive and accessible, but on the whole be considered the property from residential property owners. He said the property owners of the decoration in check, had told the other prohibiting the installation of solar energy. A few kilos of solar equipment, the owners usually go to the roof maintenance, roof load would pose a threat. The wall-mounted solar energy will affect the load-bearing walls, there are security risks, and that \"even if the property allows the installation, the owners live on the top floor will agree?\"

     Many owners are living in the attic of the roof installation \"solar\" opposed.

     Relevant departments: installation requires consent of all owners

     Installation of residential solar water heater can? Owners and property companies and uncompromising. This issue, the reporter interviewed the relevant departments.

     City Housing Authority official said the office property, property interests from all owners to prohibit the owners to install solar water heaters. External walls and roofs of residential buildings owned by the owners, such as the unauthorized installation of \"solar\" violation of the rights of other owners, will make the property into a dilemma.

     Henan ZHANG Zhen-Song YE Feng law firm\\ s lawyers that the residential building roofs and external walls are the owners, in the above installation of solar and other ancillary facilities and equipment, may affect the quality of the roof or wall. Owners subject to all of the owners or owners consent of Congress, installation behavior considered legal. Thus, if quality problems arise later, by the persons responsible maintenance responsibility; if not responsible, then the use of housing maintenance fund to solve the problem

     Look forward to: New real estate can solve the problem

     It is understood that China\\ s \"Renewable Energy Law\" clearly defined, to encourage units and individuals to install and use s, solar heating heating and cooling systems. Developers should design and construction of buildings for the utilization of solar energy to provide the necessary conditions. Buildings have been built, residents can not affect the quality and safety of the premise installation and product standards meet the technical specifications of the solar system.

     City housing and urban development committee (hereinafter referred to as the Municipal Construction Commission) Science and Technology Management Division is responsible surnamed Zhang said, although the installation of energy saving and environmentally friendly solar energy is both a good thing, but it should also consider the practical issues. He said, \"Renewable Energy Law\" in guiding the relevant provisions of the regulations, does not require enforcement, and real estate developers in order to reduce costs, design, development, installation of solar energy can be real estate, not positive.

     The official said, it is worth looking forward to that, shortly before the Municipal Construction Commission has issued relevant documents, required in the new real estate in the city 12 floors below (contains 12 layers) to implement the construction and building integrated solar systems, that is building a unified use of solar energy systems, applied to each household. It is understood that the document will be enforced in October this year.

[REVIEW] now in summer, all kinds of brand \"solar\" heat up sales. Many people regard the sights on , one can save electricity save energy, and second, to use a safe, environmentally friendly.

      Right now in summer, all kinds of brand \"solar\" heat up sales. Many people regard the sights on home , one can save electricity save energy, and second, to use a safe, environmentally friendly. Ms. Zou is such a plan the city, she ran several stores after the discovery of Yantai, the original price of solar water heater is not generally high, compared to electric water heater to the price of 1,000 yuan, the price of solar energy from 2500 ranging from seven or eight thousand dollars, the model also varied, the most surprising is that some of her brand even have to pay their own installation. Suanlaisuanqu buy than electric water heater solar water heater is not much money do province.

The price gap getting bigger very expensive not more than 5,000 cost-effective

In a circle down, Yantai city to the \"Emperor Ming\" the most expensive, ordinary 140 l of the final product prices are more than 3700 yuan, 160 liters is as high as 5,000 yuan, four seasons Mu-song, in Section sky, 100 million energy, such as Le Sang slightly cheaper.

Assuming and electric water heaters are the life of 10 years, the use of cost, electric water heater to 600 yuan a year in electricity, solar water heaters are generally electric heating in winter, electricity counted 100 yuan, 10 Province 5000 yuan. Purchase costs, electric water heater 1,000 yuan pretty good, and buy electric water heater solar water heaters more expensive than a lot of good products 150 liters complete down to 4,000 yuan, more than 3,000 yuan more expensive electricity. Considering the purchase cost and running cost, the use of solar water heaters 10 years 2,000 yuan province, so most people think that if more than 5,000 yuan solar water heater on in the economy there is no advantage.

Installation price in advance to say hello when you do not taken advantage

If you think that after buying the water heater after paying off once and for all the case, it would be wrong. Since there is no current national industry standards in the field, and therefore a lot of hidden price tricky, some manufacturers will assist heating and other configuration listed in the offer, the contract or re-installation charge, twice pricing. Devices such as automatic Sheung Shui, water level indicator, solenoid valve. Such as industry, the famous \"Emperor Ming\" installation to another pay about 700 yuan, the device automatically Sheung Shui Division Blue Sky brand to add $ 400, while the outer layer of insulation when installed devices must be paid separately.

Add some additional features seem advanced, but too many component parts, reliability is not high, over time it is easy to go wrong. This can not help but question: Since the need for so many additional devices, why not save the production process be added when installing add? Doing some of the brands seemingly cheap price, added to the final cost of 3,000 yuan in need.

Domestic solar water heaters are durable consumer goods, and is usually installed in the roof, once a fault, the user is difficult to solve, so the service must be protected. Currently, the market machine free warranty period is generally 3 to 5 years

     \"Inexhaustible solar energy, the state encourages the use of clean energy.\" With the hot weather, should usher in the usual peak sales of solar water heaters, solar water heater recently I visited some of the dealership, but found that buyers and sellers are sigh: in the urban area of ??some new solar water heater how safe is it so hard!

      City: tenants want to buy equipment to prevent

      Mr Li in Xingqing Garden District B District Jiangnan district bought a new house, decorated house plan to install a solar water heater, but now face a dilemma, let residential property security. He believes that now the whole society in the promotion of green energy, the behavior is probably connected with property contrary to the idea.

      Subsequently, I visited Yinchuan more cells, found in recent years, some of the new district will not allow the installation of solar water heaters. Owner Yang complained: \"Using electric water heaters, each warm bath before going for a long time, and power consumption is very large, people want to spend a month doing tens of dollars, he wanted a solar water heater safety, but property companies to prevent installation on the grounds that \"residential interior decoration Management Services Agreement\" shall not install solar water heaters on the roof. \"

      Property: damage to the roof waterproofing

      Why not let the new installation of residential solar water heater? Yinchuan I interviewed several property management companies. Property explains the company\\ s staff does not agree to install solar water heaters, the reason, first of all floors of the structure will cause problems, there is likely to cause water leakage and other issues. As the district is not considered in the development of the design installation of solar water heaters, if residents are now installed solar water heater, then the roof of the load-bearing capacity will be affected, there may be damage to the waterproof layer. And because real estate does not allow the water pipes through the roof, the owner if the installation of solar water heaters, water and ventilation pipes from the pipeline will generally go, this is bound to affect ventilation. And some residential building plot is the steeple of the rain the whole structure, if the households to install solar on the roof, simply can not be fixed. \"If there are problems, we can not take responsibility, which is to consider the interests of tenants.\"

      Secondly, as the owners to buy water heater brands, different specifications, will destroy the appearance of the building face.

      Rural areas: solar water heater popular

      Since some cities allow installation of new residential solar water heater, so give households install solar water heaters are not designed to repel the roof with a small number of new homes. Lake Street a solar store owner said that in recent years decreased sales of solar water heaters, and now sell 20 a month or so, mostly rural households and households in some of the old district.

      \"Before taking a bath at home are in the bathroom hanging buckets, electricity to hot water, particularly electricity and now my house is also fitted with a solar day, came back from the ground can take a shower, really convenient … … \"Lingwu City Huaqiao Zhen, a villager surnamed Zhang said.

      I visited in the know, only Helan County Department of warm spring farm there are three solar water heater stores, of which more than 20 households have installed solar water heaters. Helan County, Warm Springs Farm store a solar water heater Ms. Lee said: \"can not pass gas in rural areas, but most of the cottage, we also live in scattered, due to the solar water heater safety, energy conservation, environmental, economic, so many people choose to install solar water heater, so shop in the rural areas, but also future sales trends in the market … \"

      Should be encouraged and building integrated solar technology

Why market has stagnated in Xinjiang

[REVIEW] as the most promising new energy sources, solar energy industry is seen as energy saving targets to complete the \"vanguard.\" Solar resource is a clean environment and save unlimited resources, solar energy products and the traditional coal, oil, electricity, gas and other energy sources, the higher one-time investment, but its long term use of time, it is very cost-effective of.

     As the most promising new energy sources, solar energy industry is seen as a complete energy saving targets the \"vanguard.\" Solar resource is a clean environment and save unlimited resources, solar energy products and the traditional coal, oil, electricity, gas and other energy sources, the higher one-time investment, but its long term use of time, it is very cost-effective of. The popularity of , saving money, in line with the requirements of building a conservation-oriented society. Some people in Urumqi calculations, since the installation of solar water heaters at home, one year can save electricity more than 600 yuan. A solar water heater by now priced at 1,000 yuan terms, equivalent to only 3 years of electricity, and solar water heaters are generally in the life of more than 15 years.

      But with gas water heaters and electric water heater, if you want to towns in Xinjiang to promote solar water heaters have a long way to go. Not only is the capital of Xinjiang – Urumqi, there are difficult issues to promote solar water heaters. The main reason is the often encountered when installing and using the \"threshold\", as the development of Xinjiang, the biggest bottleneck of solar water heaters.

      Although the innate good condition, however, the manufacturers of solar water heaters in Xinjiang marketing, they encountered many obstacles. Some owners of residential solar water heater, you encounter a block of residential property. Official said residential property owners to install solar water heater, easy to damage the waterproof layer, causing housing leakage; if the top floor of the load-bearing design deficiencies, safety problems will be planted. In fact, the formal installation of solar water heaters, there are strict in the process, they will not damage the roof.

      Installation of solar water heaters suffered a bottleneck, there is one important reason is mainly the property and some developers might affect the district\\ s overall image and the emergence of other problems, many developers and even the \"limit the installation of solar water heaters,\" Check written into the contract directly, and when explicitly told the owners to collect the keys.

      It is understood that 60% of developers and property companies almost not to install the remaining 40% still charge a \"setup fee.\" In some area businesses if it is to install, you need every month to pay residential property ranging from 200-500 yuan a \"setup fee.\" \"Paid the money into the area can still be good, and some communities did not get in, because there are other businesses buy solar water heater in advance \\ installed power\\ in general, buy a dozen buildings with two to three of residential solar water heaters \\ installation right\\ , you need to pay two or three million of property. \"It is understood that before the installation of solar water heaters need to\" public relations \"a large number of district. These so-called \"installation fee\" or buy \"installed power\" costs, businesses will be shared equally in the price of solar water heaters in each, or pay the ultimate owners.

      In addition, more and more high-rise building to the development of high floor facing the aqueduct would be too long, placed solar panels smaller space and other issues. Reflect many of the solar water heater distributor, into the difficult area of ??solar water heaters have become dealers in sales and marketing process, the most troublesome problem, which not only seriously hindered the number of users of solar water heaters, and solar energy industry for the development of Xinjiang, has an absolute the impact.

      Break bottlenecks in Xinjiang solar water heater marketing strategy

      Xinjiang is not the face of solar water heater business and property, the installation and various obstacles standing still, but have to act, through a variety of ways to calculate looking forward to a way out.

Solar water heater: Vacuum and flat road game

[REVIEW] flat-plate solar collector system is most suitable for pressure and secondary circulatory system of the solar collector, while the integration with the building, with easy integration with the building facade, easy installation and operation and maintenance, long life other advantages, to promote practical flat panel solar water heater is to narrow the gap with the international advanced level is an important way.

     Flat-plate solar collectors are suited for pressure systems and secondary circulatory system of the solar collector, while the integration with the building, with easy integration with the building facade, easy installation and operation and maintenance, long life and other advantages, to promote practical flat-plate solar water heater is to narrow the gap with the international advanced level is an important way.

\"Vacuum\" mainstream

According to reports, China\\ s are mainly two: s and flat-type water heater, water heater vacuum tube which occupy more than 90% market share, which the international counterparts dubbed the \"water heater China phenomenon.\" Because, on a global scale to vacuum tube solar water heaters based only our country.

With the process of urban development have sprung up multi-layer and high-rise buildings, the vacuum tube solar water heater installation and use of a challenge. As the multi-storey buildings and high-rise building roof area is not enough, should adopt the balcony-type or wall-type solar water heater. Vacuum tube is fragile, easily aging sealing gasket leaking, the balcony or wall installation security risk.

Flow using copper pipe, plate glass produced using flat plate solar collectors can load 1500 kg, the whole system safe and reliable components, combined with a higher degree of construction, especially suitable for installation on the balcony and the building\\ s exterior walls body, so that breaches of the solar water heater into a safe and reliable times. System is designed for flat panel solar water heater pressure, constant pressure, large flow, bringing more people bathing pleasure, and the resistance to corrosion, scale-free, clean water to meet urban living style, will promote the solar industry, urbanization the process.

China Rural Energy Industry Association Professional Committee Luo Zhentao utilization of solar energy in the analysis of foreign applications in flat panel solar water heater, said the main reason: flat panel solar water heater under pressure, long life, easy to form the secondary loop system; easily combined with the construction, easy installation, easy to design; Third, the system safe and reliable.

\"Flat\" obvious advantages

Since the flat-plate solar water heater better, then why only our vacuum products become absolutely mainstream?

\"Relatively speaking, the vacuum tube type now there is no threshold.\" Deeply understands one of the industry, \"in some places, some people buy vacuum tube solar water heater parts, an assembly to sell them, but how the quality of follow-up technical support, equipment maintenance how, you have to look at the purchaser\\ s luck. \"

The formal large vacuum tube solar water heater manufacturers to products based products, it is by historical reasons. 80 to 90 years of last century, when China\\ s first use of natural circulation type solar water heater plate temperature requirements above 0 ?, can be compared to vacuum-type work at about minus 10 ?. Although the performance, the flat type has many advantages, but this can not be fatal to enter the country.

\"But the feeling from the actual use, the vacuum tube type is always in the \\ can\\ scope, but also reach the \\ easy\\ .\" One of the industry, due to the vacuum tube type because of cost considerations, the general use of non-bearing water tank, so when hot and cold water flow instability phenomenon, and water quality are generally two types of water.

[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.
