It stands to reason, energy saving is a good thing and should be welcomed by urban and rural residents. However, Beijing Information Science and Technology University \"The Sun Heart\" environmental group\\ s recent student survey showed that China\\ s current family of use the South is stronger than the north, strong in rural areas in the city, further restricting the promotion of solar water heaters, there are many factors.
The first is the government seriously enough. At present, encourage and promote solar water heaters, including various types of energy facilities, including a number of policies and regulations, but more by the ministries or local governments, systematic, mandatory poor. Incentives to implement policy, not many. Such as the Beijing Municipal Development and Reform Commission issued the subsidy policy, new and existing buildings to add various types of solar water heater subsidy per square meter of collector 200, the intensity is indeed very high. However, the survey shows that consumers do not use solar energy to understand this policy and only 6.92%, knowing that accounted for 19.23%, do not know and do not know accounted for 73.84%. Interested because they do not understand is not an important reason for interest is not directly see the benefits. In fact, 92.43% of people want the money direct state subsidies to the buyers, 83.91% of people said that if given the appropriate state subsidies, are willing to change their own water heater solar water heater. Without subsidies, it is willing to replace the solar water heater and only 25.77%. It seems, that subsidy is not enough light, but also the people by way of subsidies approved.
Survey shows that urban consumers lack a basic understanding of solar energy, some people have doubts about the use of solar water heaters, the first reaction is \"do not fly.\" Main concern is the fear of the solar water heater is not to force, in fact, one of the photovoltaic solar water heaters and electric water heater as easy to use. The other is the fear of installed solar water heaters will destroy the existing toilet facilities, in fact, the solar water heater tank on the roof, but a more efficient place. Consumers already use solar water heaters, most expressed satisfaction. This emergence of a puzzling phenomenon: the use of said well, no not with the firm. Visible, increase the popularization of solar energy equipment, is very important.
Meanwhile, some consumers have this subconscious: we do not lack that city money. They thought that the use of solar water heater is poor. No solar energy users, 56.78% of people think that you can not use the water heater economic accounts, as long as the Haojiu Hang. They do not spend money on energy dismissive.
In addition, because the developer did not take into account the construction of solar water heater installation, use, making the top floor residents use solar water heaters are extremely limited. Cities involved in the investigation of solar water heater users, only 7.4% of high-rise residents. Most of the remaining 10 floors below the lower floor or cottage residents. There are some residential property to develop \"local policies\", determined not to allow residents to install solar water heaters.
As the sales difficulties, so that some companies simply do not consider the city to do the solar market, the major building materials in recent years, Beijing is difficult to find even on the market stalls selling solar energy. Urban consumers do not accept, solar water heaters have become a major pain.
