The 2026 German Large Heat Pump Congress will bring together key players in the heat transition in Berlin on the 9th and 10th of June 2026. The focus will be on practical solutions for the successful deployment of large heat pumps in industry, neighbourhoods, district heating networks and non-residential buildings.
The congress will examine the key success factors for large heat pump projects: innovative financing models for the heat transition, mobile and modularised supply solutions for greater flexibility and faster implementation, and the economic viability of large heat pumps based on robust key performance indicators and real-world operational experience. Specialist presentations, project reports and moderated discussions will provide guidance for investment and transformation decisions.
The German Large Heat Pump Congress is aimed at operators, investors, local authorities, planners and technology providers who wish to actively shape decarbonisation on a large scale.
4-Dena-Credits:
The training course counts towards the renewal of registration on the Energy Efficiency Experts List with 4 teaching units (residential buildings), 4 teaching units (non-residential buildings) and 4 teaching units (energy audit DIN 16247/Contracting (BAFA)).
