Overview

• Co2online forecasts the annual bill for a gas-heated 70 m² apartment to reach about €1,180 in 2025, with district heating at roughly €1,245, heating oil near €1,055, pellets around €740, and heat pumps about €715.
• The report says nine in ten households could cut costs by roughly €400 a year through simple steps such as lowering room temperatures, optimizing heating settings, and improving maintenance.
• Long-term projections indicate the cost of heating with gas and oil could roughly triple over 20 years due to higher CO2 prices and rising gas network fees, while district heating and pellets may roughly double and heat pumps show the most favorable outlook.
• The Heizspiegel sets consumption benchmarks, including average annual use of 7,980 kWh of gas and 8,610 kWh of heating oil for a 70 m² apartment, with about 15,730 kWh (gas) and 21,450 kWh (oil) for a 130 m² single-family house.
• Affordability pressures remain significant, with about 4.2 million people living in households behind on energy payments in 2024, even as heating-oil quotes have eased slightly and buyers are advised to order off-season, compare prices, and consider group purchases.
