There are good reasons to wish for a future with more heat pumps: less fossil gas in the heating sector and therefore less methane leakage and less CO2 and NOx emissions; lower costs for households; and more energy independence for nations. Most of this works best with powering the heat pumps with a bigger share of renewables. In Europe, heat pumps boomed until 2023 and then dipped to 2020 or 2021 levels in 2024. Starting points and paces of change in the heat pump market differ wildly. Let’s have a virtual trip to Sweden, France and Germany and find out why those timelines are so different.
