Observations from a Long-time Practitioner in Heating Industry

As a practitioner working in the heating industry for over four decades, I have experienced various ways of heating in winter of North China, witnessed and participated in the development of the heating industry from the use of traditional coal-fired boilers to the exploration and application of non-combustion clean heating with geothermal heat pumps. It has been my daily work to deal with all matters related to heating, including ensuring production security, guaranteeing energy supply sufficiency, addressing issues of air pollution, solid waste disposal, and groundwater quality maintenance.

Years of practical experience on the front line of heating industry in China engraved in my mind the minimum heating temperature required by the Government in winter of North China. To ensure efficiency and effectiveness of the entire operation of installed heating systems, it is critical to acquire the safest and most reliable energy supply and constantly improv and pursue technology optimization and innovations of heating systems, under the premise of being environmental friendly, and convenient in operation. Today, winter heating in northern regions of China has evolved into an emerging industry primarily focused on clean heating systems using geothermal heat pumps, as an integrated system that provides heating in winter and cooling in summer.

Both theory and practice have proven that under the goals of environmental protection and "dual carbon," the development of the integrated heating and cooling industry driven by new productive forces requires significantly lower input in system construction and operations, compared to traditional way of providing heating, cooling, and domestic hot water via separate systems. Now, combustion-free and zero-emission heating can easily be achieved in designated heating areas.

"As warm as spring" is people's continuous pursuit and beautiful aspiration for "warmth" in winter. There has been unremitting efforts made in exploring ways to achieve this. From searching for and utilizing natural caves to artificially digging and building cave dwellings, all reflect the people's understanding and wisdom of nature. Looking back at the original and simple cave constructions, all manifest people's wisdom in utilizing the abundant source of natural low-temperature thermal energy (shallow geothermal energy), utilizing natural insulation layers to maintain space temperature, and using solar radiation through windows for heat supplementation. Today, with the development of technology and system application integration, the integrated heating and cooling system utilizes mature heat pump technology to exchange and accumulate heat by transporting vast amounts of low-temperature thermal energy, which successfully replaces traditional fossil energy heating at the same cost. It stably ensures that people enjoy warmth in winter, coolness in summer, and domestic hot water in an environmentally friendly manner, therefore improving people's quality of life!

The over forty years experience in heating industry makes me feel proud, despite of numerous setbacks. All efforts pay off when I see development of new technology and equipment bringing warmth, comfort and happiness to thousands of households. I will remain committed to contribute more to promoting clean heating and ensuring a warm winter for the general public.
