There is such a multiple-choice: a family of three homes, electricity water heaters, the use of the cost is more than 800 yuan a year, the electricity consumption of 1600 kwh, equivalent to 0.64 tons of standard coal, sulfur dioxide emissions 48 kg; use of solar water heaters, consumption of non-renewable Energy 0, 0 caused by carbon emissions. I would like to ask the family will choose what kind of water heater?

In the face of the title, 100% of the theory of solar water heaters will be elected, but only theoretical, since in real life, to make such a choice were less than 1%.

From theory to reality for 99 percent of what is lost?

Install solar water heaters is not easy

In recent days, Wanke, who lives in Nanchang Sijihuacheng Miss Zhang's company received a property improvement notice sent by the deadline, she said home solar water heater when admitted to a violation of the signed agreement, which must be dismantled.

Miss Zhang said that the property company said the agreement means that when submitted to the property and the owners entered into a terms, including the owners are not allowed to install solar water heaters, are not allowed to closure, such as Nanyang Taiwan. "As we all abide by the beginning of a good, but over the past two years, with the gas and other energy prices, in particular, have been on the top floor of the owner of this breakthrough in terms of installed solar water heaters." Vanke Sijihuacheng another owner Liu President said: "At first, the property company will be to intervene in order to allow owners to tear down an agreement on the ground, but they turn a blind eye, just under a deadline to give up the rectification notice."

Although Miss Zhang received a correction notice, but on a hot water bath to wash. Nanchang, who lives in a district Mr. Wang will not be so lucky. Mr. Wang lives in the fourth floor, he spent half a month's time and the top floor of the owners of consultations, "a smiling face is lost, is invited to dine," finally agreed to let other people put on their roof in solar water heaters. But after a clearance, where the property is resistance, he said that the installation of cross-layer hot and cold water pipes, damage to the exterior structure, "spent more than 4000 yuan to buy the water heater released insisted that the two have no access to."

According to a brand of a solar water heater sales manager, store them on average every month more than 10 Taiwan as a result of the installation of the product and can not return. There are two types of obstruction about the reasons, one of the property to interfere in the company, and the other is on the top floor of the downstairs from the owners of the equipment owners.

Solar water heaters in possession of hidden dangers

Residents and vendors have to play in the board's possession of the property, but property companies have Huayao Jiang.

October 26, a real estate property to Zhang Jingli company to a reporter's high-rise residential rooftops. 7 placed side by side here, solar water heaters, a surprised look. Lou Dixia appears to be dressed from the solar water heater "filth": rusting base; below the water tank and vacuum tubes, the plot and a layer of guano soil. Zhang Jingli said that the owners have installed solar water heaters will not say after, despite the wind and rain, rust gradually rotten base, a long time, the wind will be able to lift it to the solar water heater, causing accidents, at present, Nanchang Area have occurred in this case. In addition, the row of solar water heaters to the place, it will become the sun and the birds are sheltered by the benefits, so that the rooftops of the dead has become a health risk hotbed of Health.

Zhang Jingli, pointing to another floor of a residential hanging wall of the pipe 56, said: "These pipes are solar water heaters hot and cold water pipes, the owners are directly from the external walls of these holes and out of the water main, This undermines the performance of the external walls of water, the owners are in trouble is to find a property company, which is that we do not install solar water heaters is a major reason. "

In addition to housing, have an impact on the city, some of the solar water heater of the quality of their existence is also worrying. It is understood that the only market in Nanchang, there are more than 300 solar water heater the size of the brand. These product quality resource that pays top academics, uneven. By lightning, for example, remain high for the roof of the solar water heater, it is a basic requirement. However, in Nanchang City of the rainy season, from time to time there will be solar water heaters have been struck by lightning the case. According to the provincial meteorological bureau Center for Lightning to incomplete statistics, only in June 2007 of the week, Nanchang has more than 30 solar water heaters have been destroyed. In the early 2006's, including the province's 14 provinces and cities, the consumer association also issued a rare joint consumer alert to remind consumers to buy solar water heaters should pay attention to quality.

The promotion of new energy, when the Government has to

It is understood that at present, construction of China's total social energy consumption accounts for about 30 percent of energy consumption, energy consumption and construction, energy and domestic hot water accounts for about 45% of the share. This shows that the promotion of solar water heaters for energy saving and environmental protection is very important.

During the interview, property companies, solar water heaters that are vendors, it is necessary to solve the solar water heater current bottleneck in the promotion, the key is to break with its energy-saving building between the "Liang Zhangpi" pattern, so that when the construction of housing in the pre-solar water heater Leave room for the formation of the overall integration. Jan 1, 2006 from the implementation of the "Renewable Energy Law" explicitly states: "The state encourages units and individuals to install and use solar water heating systems, solar energy heating system, heating and cooling. Real estate development companies in building shall be The design and construction for the use of solar energy to provide the necessary conditions. Have been completed on the buildings, tenants may not affect the quality and safety in line with the premise of the installation of product standards and technical specifications of the use of solar energy systems, "" obstruction of the installation of solar energy use System, be punished by related departments. "

Unfortunately, although there are legal support, "Liang Zhangpi" pattern is still widespread, as it will "increase the cost of construction", many new properties for sale has not set aside for solar water heaters under the space. Provincial Department of Construction Survey and Design and Standards Department have also fixed frankly, the state and province have not yet issued specific implementation details of the current promotion of energy-saving buildings only stay in the new materials, new designs, new energy is also exploring the use of these .

People believe that the use of new energy into the relationship between energy saving and environmental protection, related to sustainable development, the Government should have a forward-looking, and actively guide and promote the benefits the country.
