Heat pumps cheaper to operate than gas boilers in almost all EU countries, IEA claims

The International Energy Agency (IEA) has confirmed that, based on 2025 prices, heat pumps are cheaper to operate than gas boilers in almost all EU countries, with potential annual savings of up to €800 ($924). This finding underscores the growing economic viability of heat pumps for residential and industrial heating, with implications for energy policy and climate goals.

The IEA’s analysis indicates that heat pumps have lower lifetime costs than gas boilers in 17 EU countries, covering around 40% of low-temperature industrial heat demand. In the residential sector, heat pumps are cost-competitive with gas boilers in 16 countries, representing about one-third of EU space heating demand. Despite these advantages, deployment remains limited outside leading markets such as the Nordics, France, Germany, and Portugal, largely due to higher upfront costs and installation challenges.

The agency highlights that, in most cases, the annual operational savings from heat pumps can reach €800, making them a financially attractive option. However, initial purchase and installation costs still favor gas boilers, which are more familiar and cheaper initially. Policy measures like low-interest financing and targeted subsidies are recommended to boost adoption, especially in countries where cost differences are minimal.

Additionally, the IEA notes that some markets, including Denmark, Germany, and the Netherlands, are already implementing policies such as reduced grid fees for flexible demand to improve electrification economics. The analysis also emphasizes that the energy price ratio between electricity and gas significantly influences the cost competitiveness of heat pumps, with regional variations affecting adoption rates.

Implications for EU Energy Transition and Climate Goals

This confirmation that heat pumps are more cost-effective than gas boilers in most EU countries supports the EU’s efforts to reduce dependence on fossil fuels and cut greenhouse gas emissions. Widespread adoption could lead to substantial energy savings, lower consumer costs, and improved air quality. It also highlights the need for targeted policy support to overcome deployment barriers and accelerate the transition to electrified heating systems, which are essential for meeting climate commitments.

EU Heating Market and Policy Landscape

Despite the proven cost benefits, heat pump deployment remains uneven across the EU. The IEA’s analysis shows that market structures, policy design, and upfront costs are key barriers. Countries like Denmark, Germany, and Portugal have made significant progress through supportive policies, while others lag due to high initial costs and infrastructure constraints. The EU’s broader energy strategy emphasizes electrification and renewable integration, with mechanisms like the EU Grids Package aimed at reducing barriers and facilitating infrastructure upgrades for heat pump deployment.

Historically, gas boilers have dominated the heating market due to lower initial costs and familiarity. However, recent price trends and technological improvements are shifting the economic balance, especially as the EU seeks to meet its climate targets under the European Green Deal.

Remaining Questions on Deployment and Policy Impact

It is still unclear how quickly and widely heat pumps will be adopted across all EU countries, given persistent barriers such as upfront costs, installation complexity, and policy variations. The actual impact of proposed policy measures remains to be seen as countries implement and evaluate these strategies.

Policy Measures and Market Developments to Watch

Next steps include monitoring the rollout of supportive policies like subsidies, financing schemes, and grid infrastructure upgrades. Further analysis is expected on how regional differences in energy prices and consumer behavior influence adoption rates. The EU’s ongoing policy initiatives, including the EU Grids Package, will play a critical role in shaping the future landscape of heat pump deployment.

Key Questions

Why are heat pumps more cost-effective than gas boilers in most EU countries?

Heat pumps typically have lower operational costs due to higher efficiency and potential energy savings, making them cheaper to run than gas boilers over their lifetime in most regions.

What are the main barriers to wider heat pump adoption in the EU?

High upfront costs, installation complexity, infrastructure constraints, and policy variations are key barriers that limit deployment despite cost advantages.

How can policy support accelerate heat pump adoption?

Measures such as subsidies, low-interest financing, reduced grid fees, and streamlined permitting can lower barriers and encourage consumers and industries to switch to heat pumps.

Will heat pumps replace gas boilers everywhere in the EU?

While many countries will see increased adoption, regional differences in costs, climate, and policy will influence the speed and extent of replacement, making a universal shift unlikely in the near term.

What does this mean for consumers and the environment?

Consumers can expect lower energy bills and improved indoor comfort, while widespread heat pump use will reduce reliance on fossil fuels and lower emissions, supporting climate goals.
