On the freezing measures
[REVIEW] northern s often such a failure occurs: in winter the temperature is low, the water heater back to the water frozen into ice, can not flow, causing water heater can not be used, the inconvenience to people\\ s lives. This paper on the causes and prevention of such failure to make a brief rule of measure.
Northern Solar Water Heater often such a failure occurs: in winter the temperature is low, the water heater back to the water frozen into ice, can not flow, causing water heater can not be used, the inconvenience to people\\ s lives. This paper on the causes and prevention of such failure to make a brief rule of measure.
First, the reasons for failure to form
Failure to the environmental conditions: the northern region in winter, especially in cold areas, resettlement, water heater return pipe (the pipe) from the flue or through tube wells.
Figure 1 shows a diagram of the formation of water heater failure, this failure is due to the formation of bends in installation pipe, some pipe against the wall, resulting in ice.
Figure two reasons for failure analysis of the formation is as follows: In winter, the outdoor temperature is low, combined with adverse external wall insulation, wall, wall temperature is below 0 ?, water pipes near the wall, but also speed up the transfer of heat, so that the pipe temperature gradually decreased. Tube in the flow of water though the water temperature has dropped, but not frozen. Most water heater is not used at night, a long tube of water at rest, the water temperature gradually decreased, until the ice. When the full pipe cross-section of Icy and has a certain length, then the water blocked, water heaters will not be used.
Second, the failure of several solutions
1 Remove the water at one end, if we determine the approximate location of the ice, then remove from the ice closer to one end of the wire through the pipes, and gradually forced to make ice activities or broken, as long as there is very little flow through, which will be gradually melting ice, troubleshooting.
Using this approach should be noted that the question is: not sharp wire ends, so as not to puncture the pipe; if the interior end of the pipe removed, once the troubleshooting, water heater in the water will quickly drain, causing water damage, to be prepared in advance; If you remove the outside end of the pipe, the water heater tank will quickly spilled outside, should also be wary.
2 by the two ends of pipes stuck, hard shake and stretch, water in the ice due to broken or bent by the vibration of the pipe deformation by stretch straight ice broken, troubleshooting.
If the pipe is longer, the success rate of this approach is not too high.
3 to the tube-wells (flue) heating the air within the injection, usually from the lower part of the injection, the ice melted, troubleshooting.
This approach requires a heating and air-injection device.
4 block area to find water in the pipes to direct external heat to melt ice.
This means that the equipment for water, if water through tube wells (flue) is difficult to implement, difficult to find the first positioning block area, the second is affected by tube-wells (flue) limit, unless the destruction of tube wells (flue .)
Third, the preventive measures
1 For new buildings, to consider increasing the wall insulation measures, in particular parts of the tube wells insulation measures, so that the temperature inside the tube-wells will not be too low.
2 for the old building, installation of water heaters if the water in the distance is not long, you can use with the tropical over the whole line. Distance may not be suitable for use with tropical insulation of pipes, water pipes can be installed close inward, away from the wall, as far as possible through tube-wells, the water channel near the inward, away from outside walls, as far as possible through leaning against the wall of tube-well wall, this approach can often achieve the desired results.
3 other ways: (1) heating pipe through tube-wells, tube wells to improve the temperature; (2) Open the water heater at night to put out a small amount of water taps, water pipes inside to avoid freezing. However, this approach is only temporary measures, not long-term use.

Troubleshooting
How to put no hot water?
1 of reasons out of hot water, vacuum tube damage, need to replace the vacuum tube; 2, water pipes, valves or fittings leak, need to repair the water pipe; 3, high water pressure, hot water, Liu Buchu, need to transfer small water flow ; 4, multiple water heaters to have the string of water phenomenon, you need to install separate valve and shut the valve; 5, if the automatic installation of the Vice-tank, the tank may also be Vice-lax or is closed failure, leading to continuous supply of cold water, reducing the water temperature, it would need to replace the float valve and related components.
How solar energy leaks?
Solar water leakage reasons: 1, vacuum tube damaged, need to replace the vacuum tube; 2, the silicone ring Mifengbuyan or damaged, replace the silicone ring can be; 3, the overflow tube blockage, causing the tank deflated, need to replace the main water tank; 4. string of indoor water mixing valve, mixing valve needs to be adjusted to hot or cold water side. 5, the water pressure, automatic valve shut lax, need to install the valve.
Why is there an ordinary burst or deflated phenomenon?
Ability of ordinary low pressure solar water heater, and generally left a vent, or vents for blockage when installing the exhaust port diameter is too small, or drainage in Sheung Shui can not effectively relief (positive or negative ), or local water pressure is too large, the water flow exceeds the flow capacity of the exhaust port, so a bucket under pressure, will cause the water heater broke up or deflated, such as poor insulation in winter by ice blocking the vents, overflow / discharge long-term use of the material gas inlet steam heat to soften clogged vent Zhengkao; installed with exhaust, overflow pipe diameter size.
Heating power is too small, too slow warming how to do?
Now the total power consumption of urban households generally have limited capacity, and household appliances is greater, the distribution of solar water heaters heat with the majority of families with electricity capacity for the allowable range, and can be heated in advance to solve the temperature by slow problem, due to electric heater has been integrated thermostat, do not worry no one caused by the water temperature is too high or dangerous, if the water temperature control device is installed, you can set timed automatic constant temperature or heating mode.
Why solar water heater pipe easily broken?
Pipes are plastic products, in the sunlight easily weathered, particularly brittle Moreover, alternating hot and cold water pipes are often more likely to lead to reduced service life of the pipeline. Dealers in the sales of solar, the retail price basically includes the installation and material costs, customers also want cheap, in place, some of the dealers in order to take into account customers to install solar installation material costs, often using the general quality products, but the above measures are not taken in the sun, resulting in damages to the pipeline, it is recommended that customers do not consider the moment when purchasing solar energy cheaper, which leads to trouble after the sale. They can be considered normal PVC water pipe connected to the solar energy on the step, and then make the necessary insulation and sun protection materials, this will greatly improve the life of the pipeline, will reduce after-sale problems, of course, costs will also increase, which depends on the wishes of consumers.

Strong into the cost of Solar White Paper published
[REVIEW] August 9, 2010, as a successful home appliances brand, Beijing Beijing Great Hall of the strong into the solar energy released in a \"White Paper on China\\ s costs,\" the press conference, called the solar water heater business to locate high-quality low-priced, so that each farmer can afford to buy a guaranteed quality and reliable after-sales service of solar water heaters and solar water heater industry really bigger and stronger.
August 9, 2010, as a successful home appliances brand, Beijing Beijing Great Hall of the strong into the solar energy released in a \"White Paper on China\\ s solar water heater costs,\" the press conference, called the solar water heater business to locate high-quality low-priced, so that each farmers can afford to buy a guaranteed quality and reliable after-sales service of solar water heaters and solar water heater industry really bigger and stronger.
In the day\\ s news conference in the face of more than 100 media from around the country and correspondents, strong Li Jin, general manager of solar energy into solar water heater industry Dabao insider cost to the retail price of 1280 yuan Φ58-1.6m-16 branch solar water heater, for example, the price structure is as follows: vacuum 16 200 yuan, 408 yuan holding tanks, Stand 132 yuan, the sales cost: 120 yuan, profits of the manufacturers: 80, logistics costs $ 60, the channel profit: 280 million, and market model, similar to a well-known brand of performance of solar water heater, a thousand dollars cheaper, this caused a sensation in the industry.
Similarly, many industry experts, the author analyzes the current solar water heater industry has long been one of the biggest drawbacks is that the artificially high prices, a serious departure from the value and price, the farmers lack the most basic right to know; while some small workshops like plants use low prices to farmers psychology, specializing in the production of solar water heaters to low-quality low price to deceive the farmers, solar water heater product without the authority of national testing laboratories, there are serious quality problems, service is not guaranteed. Although solar water heater industry after nearly two decades of development, especially from home appliances to the countryside since 2009, solar water heaters in China\\ s rural market has long been a \"mass product\", but the farmers for solar water heaters, quality, price, service and so is \"layman\", so the face of a lot of the countryside successful brand-name products and inferior products do not know how to choose the time.
\"The full measure of the current background and expert recommendations, the Beijing Strong finally decided to publish into the solar cost solar water heater, a product to the farmers the right to know we are not opposed to brand building, but we are opposed to the name brand to reap the banner profits of the act; the same time we oppose the use of low-quality products to deceive hurt the farmers. \"Lee said at the meeting into the excitement. Li Jin said the announcement, \"White Paper on China\\ s solar water heater cost\", the purpose is to farmers with the product of solar water heater \"full right to know\" and then \"spend less money wasted, not to be kept in the dark to buy solar water heaters. \"

Low-carbon economy of the solar water heater market structure
[REVIEW] In the eyes of many people, solar water heater is just a little technical content of the industry, as long as anyone can get involved marketing channels, but in fact, it is a new energy industry, one of the few master the core technology and a leading position in the international industry. In recent years, China has developed into a solar water heater collector area of ??the world s countries, the forces that support the industry completely from the market.
Let Mu-song Seasons Solar Technology Co., Ltd. (hereinafter referred to as the Four Seasons Mu-song) Li Jun, president of a little depressed, where their solar thermal industry a bit like "concubines", although the same for the photovoltaic industry, "one mother." However, due to the state policy level, selective, so that the solar thermal industry support and long-term lack of competition in a disorderly state. In the eyes of many people, solar water heater is just a little technical content of the industry, as long as anyone can get involved marketing channels, but in fact, it is a new energy industry, one of the few to master the core technologies and international leading position on the industry. In recent years, China has developed into a solar water heater collector area of ??the world s countries, the forces that support the industry completely from the market.
Depressed more than one Li Jun, Huang Ming Solar Energy Group (hereinafter referred to as Emperor Ming) Huang Ming, chairman of the board is one of them, he was with the "seven best" to describe the solar thermal industry s position in the new energy: the greatest contribution, the greatest impact The most practical, penetration of the highest, most advanced, most input-output ratio, the Government and the lightest burden. Can be compared to the solar photovoltaic industry leader – Suntech Power billions of dollars in market value, the output of the solar thermal industry is only 500 billion yuan. This "scissors" to form a disproportionate market.
From "Platoon" to "national team"
In the past, solar thermal industry is the solar energy industry in the "wild child", but with the state to promote energy conservation, it suddenly from the "wild child" into a "who play the leading role." This dramatic scene due to a variety of good news came, the policy of home appliances to make it from the "Platoon" to become "national team", and then let it blow low-carbon economy in the past year rose by more than the sum of the previous three years, from 350 billion yuan to 600 yuan. Wong Ming domination was broken, including the Four Seasons Mu-song, sun, rain, Sang Le, Norit, including new army has become the undisputed leader in the rural market, a reputation. More than 6,000 enterprises have not come from the chaos in the pressure of cross God, believe, has been carrying Feishi supersonic aircraft to another new era.
In accordance with the revitalization of the country s new energy plan, each province, city demonstration projects 3, 4 County demonstration project to expand the solar energy to rural areas to accelerate the introduction of preferential policies. Shandong, Jiangsu, grab the front, Shandong Province, through the application of legislation to the city the amount of solar energy to 60%, rural applications increased from 5% to 20%; Jiangsu Province stipulates that from 1 January 2008, all new 12 layer below the mandatory installation of solar architecture. Let Li Jun pleased that the government restrictions from the original solar installation, documentation requirements to the introduction of mandatory installation of solar energy, "attitude of a 180-degree turn." Followed, Shenzhen, Dalian, Xiamen, Shenyang, Qingdao, Kunming, Zhengzhou, etc. have been introduced to force the installation of the relevant policy. If these cities are equipped with solar water heaters, it would be how large numbers, even if the rural market penetration of solar water heaters up to 20%, it will bring to the industry-wide sales of more than 120 billion yuan. Accomplish this goal in just a few years, more exciting is that, according to Jiang Feng, Secretary General of Chinese home appliances is expected in 2020, the amount of solar energy applications in rural China will reach 60%, sales of 3,600 billion yuan.
With some kind of magic new energy seems, allow participants to collectively excited. But suddenly bursts into an industry, its risks and costs will be behind the surface. Although to some extent it is a market-oriented industry, but will upgrade an industry with the technology, in particular in the new energy industry, if chaotic rush to invest in industrial development is clearly the law of indifference. Really stand out, with the continued competitiveness of domestic enterprises, those with technical and cost advantages of the enterprise.
In the solar thermal industry, local enterprises to master the rules of the game, technology and markets are in their hands, to the Ming emperor, the Four Seasons Mu-song, sun, rain, led by the manufacturers with the advantages of building an insurmountable double line of defense, the number of foreign players block in the country. Despite international and domestic economic situation is grim days, China solar water heater export trade grew 70 percent to 300 million U.S. dollars, but China has become the undisputed largest country in solar thermal, although a considerable portion of production in foreign digestion. In this new energy competition, Chinese companies have not lagged behind in technology, while the brand and the price of their weapons defeat the enemy. This competition forced the protagonist had to integrate a variety of resources to fight a traditional marketing war.
Eve blowout industry
Many years ago, back in the state in promoting energy conservation, but the market is really booming up, but it is nearly two years to do. If the solar water heater in 2009 before the industry is still stuck in consumer education phase, the solar water heaters after 2009 entered the popular era. This year, sales of solar water heaters, singing along, the contrarian in the next economic crisis 30% of the whole industry to achieve growth. The economic crisis sweeping the global PV industry in China into the gloom and doom, but "a female compatriots," the solar thermal industry, but because the benefit from home to the countryside and into the blowout.
New Energy is a major issue relates to the national economy, without government subsidies, a country s development of new energy industry is difficult to get up. The solar energy industry, EU governments to provide subsidies of up to 30% to 50% in 2008, South Africa will increase by 30% subsidy. Although only 13% of China s subsidies, but no one care about the past that no one asked the situation has been broken, long plagued the solar industry has untied the rope. A lot of good policy activated huge domestic market, the technology has matured and increasingly lower cost, solar water heaters make up more and more popular.
Was measured before, every square meter of solar water heaters can replace coal 150 kg per year, equivalent to saving 417 degrees, can reduce carbon dioxide, sulfur dioxide, dust and other emissions 170 kg. Therefore, if the size of enterprises reached 100 billion yuan, total promotion nearly 100 million square meters of solar water heaters can accumulate alternative to conventional energy sources of coal 20 million tons of carbon dioxide emissions 30 million tons. If the solar water heater in accordance with the life of 15-year period, equivalent to solar thermal power generation cost only 0.15 yuan / kWh, lower than the PV several times lower than conventional energy generation costs about double. There is no doubt that this is beneficial to both companies and conducive to a win-win move people s livelihood. For businesses, the key to expand the scale. In a way, the solar thermal industry is a capital-intensive, capital and the market has formed a relatively benign circle. Capital necessary to gather a small number of enterprises with good market performance, the rapid growth in this industry is about, who get first-mover advantage, whoever would be likely to embark on Hengqiang road.
"Copenhagen Climate Conference to the world s eyes are focused on energy conservation, solar energy as a new vanguard, will play a very key role." Often talked about solar energy, Li Jun will be excited, "Solar energy is not only the cleanest energy, solar thermal applications and power generation equivalent to the lowest cost, but also the most widely used. "He firmly believes that the solar thermal industry in the development of a critical point, the" solar water heater to replace the traditional electric water heater is a matter of time, water heaters, consumer choice will be the product of choice if we do not act now quickly run up, we are likely the starting point of the new backward. The market has been very intense, and if we do not do something, it may be a little late. "
In the eyes of many investors, solar thermal sound trendy, but with the color TV industry, is a quasi-sunset industry. They would rather chase excess capacity of the photovoltaic business, do not want to focus on those running fast in the market leader in solar thermal industry. But over the past two years, the solar thermal industry s extraordinary development, so they had to shift the focus to look over, they found that in the new energy industry, only the solar thermal industry will be technology, marketing and market the perfect blend.
Relative to the solar industry, solar thermal industry is more like the edge of industry technology using solar energy, but it is the home appliance industry marketing practices, and that looks like a solar water heater appliances. In fact, the solar water heater market capacity than conventional electric water heater market is much greater, at some point in the future, it will not replace the original part of the advantage eroded the market share of electric water heater. Government ready to generous subsidies spree, the market over warm welcome arms, a bright and sunny outside, who can open the door, embracing boundless Spring?

Strengthen the vitality of the marketing of
As the solar end sales competition, switch to switch distributors, closed closed, some dealers said helplessly, they know hot to use industry prospects are good, but the dealer a lot of pressure, do not know how the next step do? In the current context of the brutal competition in the industry, how solar energy dealers out of the woods, to meet the industry\\ s dawn it?
Other freelance writer, industry training expert Liu Xiaoming that the face of increasingly fierce competition in the market, dealers are closer and difficult road. In fact, the solar energy market capacity and the actual sales did not decline, in fact on the rise, decline in sales caused some dealers to die not because of the market, but some of their own sales distributors snatched by others, the face of this reality, the dealer should be adopted to strengthen the vitality of their own marketing to grab sales. Specifically the following aspects.
First, the channel extension, open a second front. As a professional solar energy products distributor, is currently doing the most to see additional retail distribution, but it is undeniable, there is still a lot of channels waiting for us to develop, but on the basis of the original opening of the second channel battlefield, the dealer\\ s sales growth can play a direct role.
1 depth distribution. The wholesale distributor to the township, and then help them engage in some promotions, this model has been used by most dealers, but why not in the village also established distribution network? Recently, Jiangsu Sunshine Solar Century, \"the depth distribution of the rural service station\" model to help Henan, Shanxi and other dealers sell a lot of goods.
(2) to enter the engineering field. In the solar industry, there are many agents specialize in engineering, basic of these agents do not do wholesale, good public relations through their own ability to get good results. Therefore, conditional dealer can go to the engineering development through recommendations, guidance, influence, etc., change the number of units of the collector project procurement category, which works with to replace other collector works. Dwyer, a dealer, such as solar energy is through the hot water engineering specializing in hotels and get the sound development of the transformation.
3 contract area, real estate together. Arising from real estate companies with sales of more common, but cooperation with the district\\ s property, contracting residential solar installation, maintenance and product supply situation, the less heard, recently there are many dealers contracting and sales through the cell greatly increased. Such as solar Sang Le Ningxia Yinchuan company\\ s largest developer and real estate companies in the room, made a lot of sales.
The second is an extension of the product with the target consumer group, the more levels of people to be sold. When the appliance industry vigorously to the new energy into the time, solar dealers, why not give yourself a new position, make a new environmentally friendly industry and energy sectors dealer? Solar water heater is just one of, if the solar water heaters based on the increase related to the new class, to bring more current sales of related products group, or add a new association of new products for urban consumers, for rural market for the rich and for the general public, can provide the corresponding products, respectively, then the dealer will be a powerful marketing course, a lot of vitality. Recently, the Austrian forces in Jiangsu Solar Star ing by adding this new class to the traditional solar water heaters to meet the needs of the rural market to urban and rural solar energy to warm to meet the needs of the rich, so rich and the poor take-dealers, marketing vitality also even more robust.
Third, cross-industry alliances, and home appliances, building materials and other industries combined. Business is poor, it must find ways to move up in the face of brand advertising, promotional activities and sales results costly and poor circumstances, many dealers want to move but it is not moving. Because moving is to spend money. Then how can we spend less but also effect? The best way is to implement a cross-industry alliance, with ceramic tile, sanitary ware, hardware, decoration, household appliances and other industries together to form the dealer brand alliances, the same cost-sharing by the few, we introduce the customer to buy mutual alliance product, while another an occasion to enhance the customer\\ s trust, operating well, will help dealers increase sales.
