    Asian city of more than 8,000 suites offer 24-hour hot water all from the solar

Unscrew the faucet there is hot water, residents can be as long as the credit card consumer hot water, overhead collector set, still lush rooftop garden … … November will be "opened its doors," the Guangzhou Asian Games City, 89 buildings, more than 8,000 suites , provides 24-hour hot water, all from solar energy.

Although experts predict, the mainstream of the future family with hot water will come from solar energy. However, solar hot water into the homes of ordinary people still face price, installation and policy three major "bottleneck." Park as a future living "model", the Asian Games City is how to solve these challenges?

Difficult one: the risk of illegally built

At present, solar energy use problems encountered on several fronts: the installation of solar water heaters sad "plan off." According to the relevant provisions of urban planning and construction, building roofs are common residents of the whole building site, are not permitted to increase the common parts of the self-use equipment, no planning, "Zhunsheng Zheng," On the roof without permission is illegal construction of solar installations. Second, the size of the collector, installation, lack of uniform standards, if you wait until after the completion of the building, in addition to the installation, to bring more security risks building and landscape damage; private owners installed on the roof of the "pot cover ", if not installed lightning protection devices, may become the largest" lead mine accomplice. "

The solution: integrated design to be built

I boarded the Asian Games Town Technical Officials Village, Building 10, the roof, I saw 6-meter-high steel frame erected on the roof, vacuum tube solar water heater collector panels on a steel frame above the shop, like the natural sun visor, and roof design seamless. The use of aerial design, solar water heater collector panels do not take up the roof area, roof of the "Hanging Gardens" is still lush. Floor surface of the hot water pipes with a special material "package" will not burn people at the rooftop leisure and play.

Residential toilet, a bath without water heater like the hotel as long as they have twisted the faucet of hot water. Some devices are equipped in each household a total of six rooms in the water, impurities in the water supply, respectively, high-quality water and domestic hot water, watering, bathing, cooking can take what. Including hot water pipes with a special smart meter, residents can be as long as the credit card consumer hot water.

"We are in the construction bidding program on the use of integrated design of solar systems, together with the construction program to be built, and designed with a roof of heavy computing loads, water requirements, plus a lightning protection device to avoid a one as each installation, the housing function may cause varying degrees of damage and the risk of illegal construction. "Guangzhou Asian Games City solar project leader Luo Huiying said.

Problem 2: the high price

High prices of solar water heaters, it has become into family s threshold. I visited the city several large appliance stores, find rare solar water heater "shadow." Suning Appliance, a sales official said, in the city s water heater market, energy water heater accounts for 2 / 3, the remaining 1 / 3 is basically a gas water heater, solar water heaters in the city basically no market share. It is understood that an ordinary gas or electric water heaters up and down the retail price is generally in the thousands, or even three or four hundred dollars of promotional items, while the price of the basic brands of solar water heaters are more than 3,000 yuan. "Although solar and energy efficient and environmentally friendly, installed after no electricity, but its first investment is a bit high." Aunt West side neighborhood off some frustration.

Solar water heater is hard for a wide variety of reasons for the rejection of residential property

[REVIEW] "Now the whole society to promote green energy, why do I want to install a solar water heater is it so hard?" Has lived mayong of Ms. Yen told reporters reflect, she lived residential property management company to prohibit owners from installing solar water heaters, determined to support environmental protection, she was powerless.

   "Now the whole society to promote green energy, why do I want to install a solar water heater is it so hard?" Of Ms. Yen has lived mayong reflected her live residential property management company to prohibit owners from installing solar water heaters, she is determined to support environmental protection do nothing.

      Visits found that Ms. Yen s troubles is not the case, the vast majority of commercial district in Dongguan have similar problems. Although the Bureau of Dongguan City in June 2007 enacted the "Dongguan City Building Energy Regulations", which includes encourage the promotion of energy-efficient building structures, materials, products, and promoting renewable energy development and utilization, the development of green buildings and so on. But the city s many residential community developers and property owners to install solar water heater company prohibit the phenomenon is still relatively common.

       Policies and local regulations have been supported, residential solar water heaters into why or difficult?

       Investigation into the area of ??solar water heaters difficult

       Ms. Yen is claimed to be impatient, she thought of the recent buy a solar water heater, one can save gas, and secondly to support environmental protection can be considered out of the force.

      "It was very simple idea, did not expect to run into such trouble." Ms. Yen said she always thought that solar water heater is installed is a very simple thing, did not consult in advance the residential property management companies, directly to the mall provides the goods, but also deposit to pay hundreds of pieces. But when the workers into the area after the installation, but it was a security block.

      A residential property management staff told Ms. Yen, never allow the installation of residential solar water heater, wall area is mainly worried about the impact the landscape, would have been against the other owners.

      Ms. Yen repeated representations, but the property management company took a tough stance, adding that even if Ms. Yen privately installed, they will send someone to remove. Ms. Yen dilemma, the deposit has been paid, no refund is possible, and solar water heaters and pretend not to, she joked throw good money after bad.

      Reporter then visited Dongguan, more than one cell, many residential property owners to reflect a similar problem. Living in the district near the Fourth Ring Road, Mr. Lu said, Dongguan City, the average annual high temperature, solar radiation in summer heat, the year the average daily temperature of 25 degrees Celsius was more than 210 days, solar energy has great potential, there is development and promotion solar energy utilization technology of favorable preconditions. And the current, gas prices remain high, both environmentally friendly and able to install solar energy savings for themselves, "Why kill two birds are not allowed to do things?"

      Products, Dongguan City, an energy company s head of marketing, Ms. Lai introduced a few years ago, Dongguan City, monthly sales of over million solar water heaters. But since 2007, the sales have been declining. The main reason is the solar water heater villa in Dongguan, the factory dormitory higher prevalence, but the last few years this market has been basically completed development, and solar water heaters has been difficult to break into ordinary commercial housing market in Dongguan. The main reason is to prevent developers and residential property management, installation of solar water heaters.
