Tracking progress 2020
Nearly 20 million households purchased heat pumps in 2019. Even if some are reversible units that only partially cover space and water heating needs, growth is evident across all primary heating markets – North America, Europe and Northern Asia. Although heat pumps have even become the most common technology in newly built houses in many countries, they meet only 5% of global building heating demand. As their share is required to triple by 2030 under the SDS, further policy support and innovation are needed to reduce upfront purchase and installation costs, remove market barriers for renovations, and improve energy performance and refrigerant alternatives.
