Overview

• Techem’s new atlas reports private heating costs jumped an average of 82% from 2021 to 2024, with thermostats turned up last winter and a further consumption increase expected this year.
• co2online’s 2025 Heizspiegel shows year-on-year price gains of roughly 20% for pellets, 15% for gas, 5% for heat pumps, and 3% for oil, driven by a long cold spell, higher CO2 pass-throughs, and tighter pellet supply.
• For a typical 70 m² apartment this year, estimated running costs average about €1,180 for gas, €1,055 for oil, €740 for pellets, and €715 for a heat pump.
• Techem’s meter-based analysis finds district heating currently the most expensive option, with wood and electricity cheapest and gas and oil in between.
• From 2027, EU emissions trading will set CO2 costs that experts say will push fossil-fuel heating prices higher, posing particular risks in Bavaria where roughly 38% of buildings use oil and about 28% use gas.
