How can a anxiety lightning protection

[REVIEW] Recently, the municipal meteorological bureau director Yang Hongming lightning led scientists to the countryside publicity lightning weather knowledge, we found that some residents in rural areas housing the city\\ s roof installed , water heaters due to the lack of these mine facilities, a move Ray\\ s problems.

      At present, solar water heaters strokes occurred in 4 cases mine incident

Recently, the Municipal Bureau of Meteorology weather mine director Yang Hongming led scientists to the countryside publicity lightning knowledge, we found that some residents in rural areas housing the city\\ s roof installed solar water heaters, water heaters due to the lack of these mine facilities, a move the hidden mine .

\"The city estimates more than 5,000 solar water heaters, and some are also installed in the school dormitory roof. Water heater installed in the roof, with a security risk, appealed to residents to promote mine awareness, mine water heater initiative to do the work without the required placement of anti- mine facilities, in accordance with relevant provisions of the law enforcement agencies can weather more than 500 yuan imposed a fine of 30,000 yuan. \"

5,000 solar water heaters move the status quo Ray

Recently, Yang Hongming housing area to a small village Lotus Township inspection mine work, we found the village several solar water heaters.

Summer is high season for thunderstorms, but the city is more than mine. This is mainly due to erosion of the hilly landscape is Suining, hilly, Gully aspect, to spread all over the canal, the middle of the low-lying four-week high, coupled with the outer edge of the subtropical high in summer climate, abundant water vapor, so prone to lightning phenomenon. The solar water heaters are generally placed in the roof, if the anxiety of mine facilities, are more vulnerable to lightning.

\"Solar water heaters, metal structures are more common with electric heating, and roof installation location is generally higher than the height of lightning rod and lightning protection zone, in the absence of effective lightning protection measures, it is easy to become a lightning target. Ranging from water heater explosion destroyed, while in direct electrical injury were the survey shows that since April this year, within the city there were 963 times the number of lightning, thunder and lightning intensity of 57.6KA. \"Yang said. \"According to preliminary estimates, the city\\ s rural areas are currently about 5,000 various types of roof water heaters, water heaters being struck by lightning cases have occurred as of now, the city, there were four events from the water heater lead mine.\"

Dealers that sell water heaters do not need lightning protection

Not long ago, as a consumer reporter came to City a solar water heater sales store and see the huge store on display at forty-five kinds of brands of solar water heaters. Boss said: \"Last year we sold more than 500, are not safe lightning protection, we use the water heater you though, no problem, because there is no sharp part of the water heater.\" Vendor of mine work on solar water heaters so indifferent, Reporters are very worried.

Product safety requirements by country, solar water heaters to be installed lightning protection facilities, and its products also have the instructions to install lightning protection facilities, notes, general dealer has failed to install, is the disregard for life and property safety of consumers.

According to reports, if mine own solar water heater deal, first distance away from the installation of water heater 3 m 1.5 m above the water heater at the top of the lightning rod, and do protect against lightning; Secondly, from the roof the introduction of solar water heater indoor power lines, signal lines, water pipes should be metal shielding; Finally, you should install leakage protection switch back-end SPD (surge protector), and do protect against lightning and the lightning induced wave intrusion.

According to statistics, Suining average number of lightning strikes up to 30 days to record up to 60 days, is more than mine. Farmers mine awareness weak, so the solar water heater installed lightning protection for these facilities is a priority. It is understood that the wall below the floor construction of solar water heater, do not worry about summer lightning problems.

Focus is to prevent an extension of flammable and explosive places

At 14:40 on August 30, 2007 about the British soaked village of Carp River County Chi Yang Hui 10 group home struck by lightning, 12-year-old student died on the spot. According to the survey, the day of the accident, lightning is the summer period, Yang Hui was at home watching TV, suddenly found TV outlet in the sparkle, immediately went to pull the plug, and instantly a strong line of lightning current through the light spot to Yang Hui fatal. According to the survey, Yang Hui\\ s family was then struck by lightning off in the area, building on top of the CCTV line lightning protection measures are not taken; Second, the overhead wires from the house side of the house too close (less than 3 meters), hundreds of thousands of volts of lightning voltage the formation of lightning counter-attack; Furthermore, the whole house is not installed lightning protection devices, power line installation is extremely irregular.

At 3:35 on August 16, 2009, Berlin Township, the village housing area Lotus group 3 a lightning accident occurred, the lightning causing Wang Chenghai residential building and the surrounding villagers were Jihuai appliances, resulting in total direct economic losses of 3.8 million. The same reason lightning lightning lightning protection devices are not installed, the roof water heater is not connected to potential measures, overhead power supply, signal line lightning protection measures are not taken.

\"Mine detection involves various sectors and systems, with emphasis on flammable and explosive places, schools, hospitals, financial institutions, construction projects and enterprises, institutions, but some units did not take the initiative to submit applications for mine safety inspection, or only a partial test. Overall, the city\\ s annual inspection of lightning protection device surface is still relatively narrow, some units can not attract enough attention, as part of the communications sector and individual enterprises, institutions, and every year its been due to lightning The loss is not small. Furthermore, is part of the construction project will be construction of lightning protection devices are not reviewed construction, after completion of the project did not pass acceptance testing will be completed and put into use in rural areas, urban building rooftop solar water heaters and other electrical devices generally do not take lightning protection measures which are very security risks. \"Yang said.

Occurrence of lightning in the atmosphere of intense discharge phenomenon, usually in a thundercloud (cumulonimbus) has happened. Lightning can be divided according to their location of occurrence of lightning within the cloud, inter-cloud lightning, cloud-air lightning and cloud-ground lightning. Cloud to ground lightning discharge is formed when the intense thermal effects, electrical effects, mechanical effects and electromagnetic effects, can be very destructive, the production of people\\ s lives and safety of a larger threat.

Most vulnerable to lightning strikes in life objects are the building angle, roof, eaves, gables, parapet; building on the exhaust, the exhaust pipe; a subsidiary of metal buildings, such as solar water heaters, etc.; tall tree; Square, playgrounds and other places of the flag; transmission and distribution lines and towers, radio tower, communication base stations, billboards and other large metal objects tall.

Who \\ s life?

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

can battle one roof to share?

[REVIEW] According to Harbin, housing security and Housing Authority property at Chen introduced, according to the \"Property Management Regulations\" and \"property law\" the relevant provisions, the roof is a common site, the owners do not allow unauthorized possession. Based on the actual situation, residents to install s must obtain residential property owners\\ committee and the top-level owner\\ s consent to install.

      Battle of illegal installation of roof

According to Harbin, housing security and Chen introduced at the Housing Authority property, according to \"Property Management Regulations\" and \"property law\" the relevant provisions, the roof is a common site, the owners do not allow unauthorized possession. Based on the actual situation, residents to install solar water heaters must obtain residential property owners\\ committee and the top-level owner\\ s consent to install.

According to introduction, part of the district and the old Harbin residents on the top floor installation of solar water heaters, and many property owners without the consent of the installation of solar water heaters produced by violations of contradictions. Top-level residents are worried that, once the equipment leaks, home suffer. Comments on behalf of the property North Pine Eagle property residential green water, said deputy general manager Liu branch, without the consent of the property agreed to the installation of solar water heater problems borne by the factory owners, but also three dozen property line. Zhang Xuan West residential property company, said the roof more than one water heater, increasing the body\\ s load-bearing floor, really unsafe.

      Three of the more obvious advantages

      Electric water heater, a solar water heater with a focus on the whole building to use solar water heaters more, what more advantage?

      According to the City relevant staff at the EPA Science and Technology Lee introduced, electric water heater more than 2,000 yuan each, according to electricity, each household to be hundreds of dollars on electricity. Install a solar water heater family spend an average of 3,000 yuan, although no power to spend money but take public space. Families do not have solar water heaters, the need to let go of the pipe in the water, drain again, Sheung Shui, it also brings water to waste. Winter ice is also prone to wandering child phenomenon, caused by safety problems. Concentration of a building using solar energy, simply install the collector unified, up and down the tank, circulating tubes and other devices, solar water heaters save energy through intelligent control system, the Four Seasons is building hundreds of households to provide hot water, saving space do not spend tariff, just take water. A number of manufacturers currently on the market are doing the project, a residential building, installation costs in the million or so, share the home as long as a few hundred dollars, and affordable.

      Step by step solution on demand

      Whole building energy-saving environmental protection, install a solar water heater can promote in Harbin? According to the City Housing Authority housing security and Publicity Minister of the Ministry, at present, Harbin is not the introduction of relevant laws and regulations to guide people in residential buildings to install solar water heaters. Currently more than 4,000 communities in Harbin City, the original, mostly flat roof, there is no stop light problem, if a residential building space for the installation of a solar water heater is not a problem, but the need for owners and property agreement.

      Some older residential buildings, the top leaking through the cold more serious, now in progress and some energy-saving residential buildings, the flat roof into a pitched roof, the owner may request the construction side, self-financing the installation of a water heater, and the design the trend line for the whole building to provide hot water. New residential developers to plan ahead, set aside real estate construction pipeline, the houses when home buyers to seek consent, unified installation of solar water heaters, the installation costs into the housing fund in the count, step by step to solve the problem. According to Minister on, the residents of Harbin City, the feasibility of building a larger concentration of solar energy, but has yet to have a building to install a solar water heater precedent.

      Heilongjiang Provincial People\\ s Congress Hou tree was proposed, housing, environmental protection, energy conservation department may be feasible to come up with specific implementation plan, according to public needs, providing technical guidance.

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.

Recently, Ms. Sun feedback, send the goods are sent to dealers Yujing Li, in addition to other outside the box is not complete, there is no other problems, water heater is new. In order to apologize to the Guotai Bo, a few days ago, Ms. Sun presented a value of 100 yuan to Guo Dabo fans, promised to give this water heater to extend the warranty period of one year, and return the parts cost him 100 yuan.

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
