A major focus of the meeting was the presentation and discussion of all eight pilot projects involved in HEAT 35 – four “beginner” pilots and four “advanced” pilots. These pilot sites represent a range of starting points and approaches to implementing renewable energy and waste heat solutions in DH systems. From cities just beginning their transformation journey to those already pioneering integrated renewable systems, the diversity of the pilots showcases the adaptability and scalability of the HEAT 35 concept across different contexts in Europe.
The meeting also included a field visit to the Tehnostan district heating system in Borovo Naselje, a suburb of Vukovar. This site combines solar thermal collectors with natural gas-based heating, illustrating a transitional approach to decarbonisation. The system serves as a real-world example of how renewable technologies can be integrated into existing infrastructure and highlights the potential for gradual yet impactful upgrades toward sustainable energy systems.
The meeting in Vukovar was a valuable occasion to strengthen partnerships, coordinate next steps, and reaffirm our joint commitment to reducing emissions in the heating sector.
Stay tuned as we continue working with local stakeholders and technical partners to implement and monitor the pilot projects, bringing us one step closer to low-temperature, high-efficiency, and climate-resilient district heating systems across Central Europe.
