📢 HEAT35 Project Partners Meet in Historic Augustinerkloster in Erfurt!

project partners gathered yesterday in the historic Augustinerkloster, located in the heart of Erfurt. The meeting took place in the former monastery closely connected to the life of the famous reformer Martin Luther, who lived there as a monk during the early 16th century.

The consortium meeting brought together project partners to review the progress of the pilot activities and to discuss the next steps as the project enters its final phase. 📊

The meeting provided an important opportunity for exchanging experiences and ensuring a coordinated approach toward the successful completion of the project. 🤝

Heating and cooling account for around half of Europe’s total energy consumption - yet many systems still rely heavily on fossil fuels.
That’s where the project comes in.

By supporting cities and regions across Central Europe, is driving the transition towards sustainable district heating systems - aiming for at least 50% renewable energy and waste heat by #2035.

Through collaboration with energy providers, public authorities, and experts, the project is developing practical tools, strategies, and a comprehensive Kit to help modernise heating systems, improve energy efficiency, and reduce emissions.

This Earth Day, we highlight the importance of:

🟢 decarbonising heating and cooling systems
🟢 integrating renewable energy and waste heat
🟢 strengthening energy resilience and security
🟢 enabling a just and sustainable energy transition

Because transforming how we heat our homes and cities is essential for protecting our planet.

🌍 Happy Earth Day!

📢 HEAT35 Kit

Discover the newly available Kit - a comprehensive toolkit designed to support district heating (DH) operators and stakeholders in planning and implementing transformation processes toward sustainable energy systems.

Developed within the project, the Kit brings together a range of existing tools, methodologies, and practical solutions into one integrated framework. It supports the transition of district heating systems towards increased use of renewable energy sources and waste heat.

The toolkit provides guidance across key transformation steps, including:
✅ development of transformation plans
✅mapping of renewable energy and waste heat sources
✅techno-economic assessment and business model support
✅stakeholder identification and engagement
✅access to supporting tools, best practices, and external resources

By consolidating knowledge and tools in one place, the Kit simplifies complex transformation processes and helps DH operators make informed, strategic decisions.

The Kit will continue to evolve, with ongoing updates and improvements provided by project partners to reflect new insights, tools, and best practices.

On 26 March 2026, an online webinar titled “District Heating Company as an Investor in Small-scale RES” was held as part of the project.
Hosted by the Cracow District Heating Company and delivered by Prof. Przemyslaw Markiewicz-Zahorski from the Cracow University of Technology, the session explored the evolving role of district heating companies in the energy transition.

🔎 Key topics included:

• Small-scale renewable energy technologies for end users
• Innovative investment and business models
• Benefits for district heating companies and customers
• Risks and implementation challenges

👉 A key takeaway:

Buildings are no longer passive consumers, they are becoming active energy hubs that generate, store, and optimize energy.

Driven by the revised Energy Performance of Buildings Directive (EPBD 2024) and the Zero-Emission Building (ZEB) standard, district heating companies must shift from heat suppliers to integrated energy service providers and investors.

Pilot projects and collaboration will be key to accelerating this transition.

HEAT 35 Project Workshop and District Heating Section Meeting in Dobrovo 🔥♻️

The District Heating Section of the Energy Chamber of Slovenia hosted a dedicated HEAT 35 project workshop during their regular meeting on 5–6 December 2025 in Dobrovo, Slovenia.

The event brought together district heating operators, energy experts, and project partners to discuss current developments and future pathways for the green transformation of district heating systems 🌱⚡.

Key presentations included:

🔹Matjaž Gerl (E-zavod) provided an overview of the key activities and achievements of the HEAT 35 project

🔹Matteo Mazzolini (APE FVG) shared insights from a pilot district heating project in Maniago, Italy 🇮🇹, utilizing surplus heat from a regional bio-waste treatment centre

🔹Christian Ramerstorfer (AEE INTEC) presented support tools and services developed within the HEAT 35 project to assist in planning the transition to renewable heat sources

The two-day event provided a valuable platform to exchange experiences, explore innovative solutions, and strengthen cooperation 🤝 among stakeholders working toward more resilient and low-carbon district heating systems.

➡️On 17 November 2025, the webinar “Waste Utilisation in Heating: Innovative Technologies from Central Europe” showcased practical solutions for decarbonising heating systems across the region.

The event was organised by Reheateast, GreetGeo Project, GREET CE Project and .

Moderated by Krisztina Dely , the session featured Pal Kiss (THERMOWATT), Balázs M. Hepp (e-Chemicals) and Szilveszter Sztruhala (HeatVentors), who presented technologies that recover unused energy, convert industrial emissions and improve heat storage efficiency.

👏 Participants learned how wastewater can be used as a renewable heat source for district heating, supported by AI tools that help cities map their energy potential. Other innovations included electrochemical conversion of captured CO₂ into valuable industrial feedstock, as well as advanced thermal batteries using phase-change materials to reduce peak loads and integrate more renewable heat.

👆 The webinar highlighted how these solutions are already shaping a cleaner, more resilient heating future in Central Europe.
