The Future of Heat Pumps in China
Heating is a very important service to society that needs to be decarbonised further. Thus, heating technologies chosen in China to reach carbon neutrality by 2060 have a major influence on global heating trends. Electrification through heat pumps can provide a key lever for decarbonising heating, particularly since sales have increased in recent years in China. The report released by the IEA provides an overview of the status of heat pumps in buildings, industry, and district heating in China, and examines potential to further accelerate their deployment.
Comprehensive Insights into Heat Pumps
Heat pumps are essential for transitioning to a low-carbon economy. They work by transferring heat from one place to another, using electricity to move heat rather than generating it. This technology is crucial for reducing greenhouse gas emissions and improving energy efficiency in heating systems.
