Adapting to the development direction of social electrification, electric heating is a major development trend. Hu Bijun said that at present, various home appliances are increasingly popular in our country, and all aspects of households are electrified, of which electric heating is of course an important part. Our country's trains and cars are all developing in the direction of electrification, and developed countries mainly use electric heating. We have no reason to reject electric heating.
Electric heating technology is highly popular in Europe and the United States, but the bottleneck of electric heating in my country is the price issue
Electric heating technology is highly popular in developed countries such as Europe and North America, with Norway accounting for the share, Japan and South Korea accounting for the share, France and Sweden accounts for more, the United States and other European countries account for more. In China, electric heating has just started. For example, Changchun City only has an electric heating area of 10,000 square meters, accounting for 50% of the city's centralized heating area.
In the past, there were often repetitions in the development process of electric heating in China. According to an official from the Yanbian Prefecture Housing and Urban-Rural Development Bureau, the guest rooms of the Yanji Postal Building Hotel once used electric heating installed on the ceiling. After three heating periods, due to the high heating electricity bills, they were forced to switch back to hot water boilers for heating.
The bottleneck of electric heating is the price issue. Wen Chengjun, director of the Jilin Provincial Urban Heating Guarantee Guidance Center, said that during the electric heating pilot process, some electricity bills were high and the price was higher than that of central heating, while some cost savings and were lower than that of central heating. The reason mainly depends on whether the building itself is energy-saving. For example, the insulation level of old buildings is not high, and the electricity bill for electric heating alone is already higher than the price of urban central heating. The use of electric heating in new energy-saving buildings will save costs.
There are two bottlenecks in the large-scale promotion of electric heating in residential buildings. One is that residents think that electric heating costs electricity, and the other is that if the entire community uses electric heating, the capacity of the external power network will be relatively high. said Wang Zhong, chairman of Shanghai Fangnan Energy Storage Heating Engineering Co., Ltd. But he believes that if energy conservation is considered in residential areas from the beginning of project construction, the cost of electric heating will be more economical than central heating.
The future of China's heating market should be electric heating, and it should be this distributed heating and centralized management model. my country is the world's second largest electricity consumer and ranks first in installed capacity. The electricity generated by various energy sources is surplus in winter. Using excess electricity for heating is also beneficial to replacing coal-fired heating and reducing smog. Wang Zhong is very optimistic about the prospects of electric heating.
Looking forward to policy support, starting from the entire industry chain, making electric heating greener and more cost-effective.
