TL;DR
The International Energy Agency has confirmed that heat pumps are cheaper to operate than gas boilers in nearly all EU countries, offering significant energy savings. However, adoption is uneven due to policy and market barriers. The report calls for stronger policy support to accelerate uptake.
The International Energy Agency (IEA) has confirmed that heat pumps are cheaper to operate than gas boilers in 17 European Union countries, representing around 40% of low-temperature thermal energy demand. This development underscores the growing economic viability of electrification technologies in the EU, with potential annual savings of up to €800 ($924) per household or industrial user. The report highlights that despite this cost advantage, deployment remains limited due to market and policy barriers.
The IEA’s analysis shows that, based on 2025 prices, heat pumps have lower lifetime costs than gas boilers in 17 EU countries, including several major markets like Germany, France, and Poland. These countries account for roughly one-third of residential space heating demand and around 40% of low-temperature industrial heat use. The agency attributes the limited adoption to high upfront costs, installation challenges, and policy gaps, despite the clear economic benefits.
In the residential sector, heat pump sales increased by 17% in the first quarter of 2026 across 11 key European markets. In these countries, the total cost of ownership for heat pumps is estimated to be 15%–30% cheaper than gas boilers outside the Nordics, Portugal, and Austria. However, in many other EU nations, the initial purchase and installation costs still favor gas boilers, although the ownership cost difference is often less than 5%, suggesting targeted subsidies could shift the balance.
The IEA emphasizes that heat pumps not only reduce energy costs but also improve indoor comfort, property values, and air quality, while decreasing reliance on fossil fuels and exposure to volatile prices. Nonetheless, the report notes that upfront costs and installation complexity remain barriers, with consumers favoring familiar, cheaper initial options. Policy measures like low-interest financing and support for building renovations are recommended to promote wider adoption.
Implications for EU Energy Transition and Policy
This confirmation that heat pumps are more cost-effective than gas boilers in most EU countries has significant implications for the EU’s climate and energy policies. Widespread adoption could substantially reduce fossil fuel dependence, lower household and industrial energy costs, and help meet climate targets. The report underscores the need for stronger policy measures, including financial incentives and infrastructure support, to overcome current deployment barriers and accelerate electrification across residential and industrial sectors.

EU Market Dynamics and Adoption Barriers
Despite the economic advantages, heat pump deployment in the EU remains uneven. Countries like Denmark, Germany, and the Netherlands are leading due to favorable policies, lower electricity-to-gas price ratios, and existing infrastructure. Conversely, markets such as France, Poland, and Germany still see high upfront costs and installation challenges, which hinder broader uptake. The IEA notes that policy support, including grid fee reductions and mechanisms like the EU Grids Package, could help address these barriers and promote faster adoption.
Historically, gas boilers have dominated EU heating markets due to lower initial costs and established supply chains. Recent price shifts and technological improvements are beginning to tilt the economic balance, but consumer habits and market structures still slow transition efforts. The report highlights that targeted subsidies and tariff reforms could make heat pumps more attractive in these lagging markets.

Remaining Questions on Deployment and Policy Impact
It is still unclear how quickly the EU will implement the recommended policy measures and whether these will be sufficient to overcome current barriers. Additionally, the long-term impacts of widespread heat pump adoption on the energy grid, infrastructure, and market dynamics are still being assessed. The actual pace of deployment in lagging countries remains uncertain, as does the influence of future energy prices and technological developments.

Next Steps for Policy and Market Adoption
European policymakers are expected to consider and implement targeted incentives, tariff reforms, and infrastructure investments to accelerate heat pump deployment. Monitoring of market responses and further analysis of cost-benefit scenarios will inform future policy adjustments. Industry stakeholders are likely to push for streamlined installation processes and financing options to reduce upfront barriers. The EU’s climate targets make rapid adoption a strategic priority, with expected increases in market penetration over the coming years.
