The AIT Austrian Institute of Technology is organising the IEA Heat Pump Conference 2026 in collaboration with international partners, driving innovation in heat pump technologies.
- The 15th IEA Heat Pump Conference 2026, with over 800 participants
- 367 scientific papers highlighting the latest developments, from research to industrial application
- Austria as a hub for innovation, with around 537,000 installed systems and significant CO₂ savings
- Heat pumps as a key technology for the decarbonisation of industry, energy systems and residential buildings
With today’s opening of the 15th IEA Heat Pump Conference 2026 at the Hofburg, Vienna will become an international hub for innovation in heat pump technologies for four days. Over 800 participants from all over the world are coming together to discuss the latest developments in research, industry and energy policy.
The conference is regarded as the leading international platform for discussion on heat pump technologies and their role in the decarbonisation of energy systems.
Austria as a hub for innovation
“The energy transition will also be decided in the heating sector. Heat pump technologies play a key role in this. Austria has developed into a major hub for innovation in this field”, emphasises Peter Hanke, Federal Minister for Innovation, Mobility and Infrastructure, in his opening speech. “Around 537,000 installed systems are already saving approximately 1.26 million tonnes of CO₂ annually, whilst simultaneously creating added value and jobs. Heat pumps demonstrate that climate protection and economic success are not mutually exclusive – on the contrary: those who invest in green technologies today are securing the jobs and markets of tomorrow.”

15th IEA Heat Pump Conference 2026: Focus on innovations in heat pump technology
With over 380 submissions from research and industry, high-ranking international speakers, workshops and technical excursions, Vienna will become the international center for heat pump innovations from 26 May to 29 May 2026.
Ticket sales are underway, and the early bird deadline has been extended to 16 March 2026.
The AIT Austrian Institute of Technology, in cooperation with the IEA Technology Collaboration Programme on Heat Pumping Technologies (HPT TCP), is organising the 15th IEA Heat Pump Conference 2026 in Vienna. Under the motto "Decarbonisation through Innovation", the international conference offers experts from research, industry, finance and politics a central platform for exchanging information on the latest developments and applications in the field of heat pump technologies. After 42 years, the international heat pump conference is returning to Austria, making Vienna the global meeting place for innovations in heat pump technology in 2026.
Internationally oriented scientific programme
The scientific programme for the four-day conference is currently being finalised. A total of around 380 contributions from all over the world have been submitted, addressing current developments in research and application of heat pump technologies.
The programme covers a wide range of formats, including:
- six plenary keynote lectures by leading international experts,
- 380 scientific presentations,
- ten interactive workshops on current technological and market-relevant topics,
- six excursions to innovative demonstration projects, and
- three policy forums on key issues of energy policy, technological competitiveness and the role of heat pump technologies in achieving climate targets.
