​The burning of a large amount of coal during winter heating in northern China has aggravated air pollution. So, is there a clean renewable energy source for winter heating? For example, what is the feasibility of solar heating? Can it be widely promoted?

On July 7, 2016, the “Implementation Opinions of the National Development and Reform Commission and the National Energy Administration on Promoting the Construction of Multi-energy Complementary Integrated Optimization Demonstration Projects” was officially issued, and the declaration of multi-energ

This paper explores some of the shortcomings of Sunpower solar water heaters and their improved methods and steps to fundamentally address the problem of wasted water. After a series of improvements, the improved Sunpower solar water heater has the outstanding advantage that in the cold north, there is no need to worry about the hot water flowing out of the water pipe.

In recent years, with the continuous high-rise construction, flat-panel solar collector systems are characterized by their high pressure resistance, long life, easy to form a secondary loop system, easy to combine with buildings, and large effective lighting area, not only in large areas abroad.

As the source of the earth, solar energy is a clean and renewable resource. The use of solar energy to achieve building heating is in line with the trend of transforming the fossil energy system into a low-carbon energy system, in line with the objective requirements of the new rural construction, and is conducive to protecting the green water and blue sky of the motherland.

Current status of solar thermal assisted energy applicationsSunpower solar thermal applications are currently concentrated in hot water projects, and heating is relatively low. For household solar water heaters, most enterprises choose to use electric auxiliary heating.
