TL;DR
The International Energy Agency (IEA) states that heat pumps are cheaper to operate than gas boilers in nearly all EU countries, promising up to €800 in annual savings. Deployment remains uneven, but policy support could accelerate adoption.
The International Energy Agency (IEA) reports that heat pumps are now cheaper to operate than gas boilers in 17 European Union countries, with potential annual savings of up to €800 ($924) per household. This development underscores the growing cost competitiveness of heat pumps, which could significantly influence energy consumption and climate policy across the EU.
The IEA’s analysis shows that, based on 2025 prices, heat pumps have lower lifetime costs than gas boilers in 17 EU countries, representing around 40% of low-temperature industrial heat demand. In residential settings, heat pumps are cost-competitive with gas boilers in 16 countries, covering approximately one-third of EU space heating demand. Despite these advantages, deployment remains limited outside leading markets like the Nordics, France, and Germany, due to factors such as high upfront costs and installation challenges.
The agency highlights that, with proper policies such as low-interest financing and targeted subsidies, adoption could accelerate. In markets like Denmark, Germany, and the Netherlands, measures such as reduced grid fees for flexible demand are already improving economics. The IEA emphasizes that, overall, heat pumps offer energy savings, longer lifespan, and benefits like improved indoor air quality, making them a promising solution for decarbonizing heating across the EU.
Implications of Widespread Heat Pump Cost-Effectiveness
This shift has major implications for the EU’s energy transition, potentially reducing dependence on imported fossil fuels, lowering household energy bills, and decreasing greenhouse gas emissions. The report suggests that policy measures are crucial to overcoming barriers like high initial costs and infrastructure constraints, especially in non-leading markets. Accelerating heat pump deployment could also support broader climate goals and energy security, making this a key development for EU energy policy.

EU Energy Market Trends and Heat Pump Adoption Patterns
The EU currently imports around 80% of its fossil fuels, with heating representing a significant portion of energy consumption. While heat pumps are recognized as the most cost-effective technology for low-temperature industrial heat, their deployment remains uneven across member states. Leading markets like the Nordics, France, and Austria have higher adoption rates, driven by favorable policies and electricity prices. In residential sectors, sales increased by 17% in early 2026, but barriers such as upfront costs and installation complexities persist in many countries, including Germany, Poland, and France.
The IEA’s analysis indicates that regional differences in electricity-to-gas price ratios and policy support significantly influence the cost competitiveness of heat pumps. The EU’s Grids Package and other policy tools are seen as potential enablers to expand adoption further, especially in industrial applications where infrastructure and capital costs are major hurdles.

Key Questions
How much money can households save with heat pumps compared to gas boilers?
Households can save up to €800 ($924) annually through lower operating costs with heat pumps, according to the IEA.
Why is deployment uneven across the EU?
Factors include high upfront costs, installation challenges, policy differences, and regional variations in electricity and gas prices.
What policies could encourage faster adoption of heat pumps?
Low-interest financing, subsidies, grid fee reductions, and infrastructure support are key policy tools recommended by the IEA.
Are heat pumps suitable for industrial heating as well?
Yes, the IEA states that heat pumps are the most cost-effective technology for low-temperature industrial heat below 150°C in the EU.
What are the main barriers to wider deployment?
High upfront costs, installation complexity, infrastructure constraints, and policy gaps are the primary barriers.
