Combating disinformation about heat pumps
“Heating bills of horror” and “Heat pump hounds” – between 2023 and 2025, the narrative about heat pumps was dominated by alarmist materials suggesting that the technology was failing. This negative message led to a decline in interest in this key solution for the energy transition. However, the source of the problems was not the pumps themselves, but the dishonest practices of a small number of installers in the Clean Air program, who – seeking profit – installed poorly selected devices, generating high electricity bills. Stiebel Eltron was one of the first manufacturers to take steps to rebuild trust, providing reliable data, case studies, and debunking emerging myths.
