Our cities are still predominantly reliant on coal and oil for energy consumption, which not only leads to energy waste but also severe environmental pollution, including air pollution. The concentration of suspended particles in the air, sulfur dioxide, carbon monoxide, and carbon dioxide exceeds safe levels, posing threats to both human health and plant growth. In response, major and medium-sized cities have successively implemented policies to address coal pollution by gradually banning the use of coal-fired boilers and household coal stoves. In contrast, electricity, as a clean energy source, holds a significant advantage.

The method of collective heating for buildings using electrical power originally developed in industrialized countries with abundant electricity. Due to insufficient electricity resources in the past, it was challenging for China to adopt and promote electrical heating. In recent years, with the continuous economic development of our country, electricity production has improved, and electricity supply has gradually shifted from scarcity to surplus. As people's living standards have been rising, the demand for electricity has also been increasing, especially with the clear winter-low and summer-high trend in electricity consumption. Therefore, the electricity sector has introduced policies to encourage electricity use during winter. Alongside the country's enhanced efforts in environmental pollution control, the superiority of electricity, this clean energy source, has been recognized and widely utilized.
