Energy crisis: In the energy war, the Germans are arming themselves with heat pumps. Visit to a booming industry

Andrea and Dieter Bosbach from Wipperfürth have finished with Vladimir Putin. In the future you will heat without its fuels. Your house is in a valley in the Bergisches Land, embedded in meadows and fields. If you drive down the dirt road to them, the mobile network says goodbye. Instead, two futuristic devices the size of a freezer stand out. There are heat pumps in Bosbach’s front yard. Machines that – physically ingenious – can draw heat from the air. Even in frost. The solar system on the roof supplies part of the operating current. Dieter Bosbach, 59, master electrician, is happy: “When the Russians attacked the Ukraine, we immediately ordered the heat pumps.”

Take that, Putin!
