Overview
- co2online’s new Heizspiegel projects 2025 costs for a typical 70 m² flat at roughly €1,180 for gas (+15%), €740 for pellets (+20%), €715 for heat pumps (+5%), €1,245 for district heat (+2%) and €1,055 for heating oil (+3%).
- Market data show an early autumn uptick for pellets, with average prices up about €7 per tonne in a week and a general pattern of lower prices in southern Germany than in the north.
- Heating-oil commentary notes geopolitical tensions are supporting crude prices, with price snapshots from HeizOel24 used to guide purchase timing advice.
- Long-term projections indicate gas and oil costs could roughly triple over 20 years, while district heat and pellets could about double, with heat pumps expected to offer the most favorable trajectory.
- Despite higher charges, co2online says many households can still save about €400 a year through temperature control, ventilation habits and technical measures such as hydraulic balancing.
