The Thuringian Heat Network Forum 2025 took place on 22 October in Erfurt, organized by ThEGA, a partner of the HEAT35 project. The event gathered around 70 representatives from local authorities, utility companies, and energy cooperatives to discuss the future of heat supply and the transformation of existing infrastructure.

This year’s forum focused on innovative technologies, funding opportunities, and practical approaches to achieving a sustainable and efficient heat transition. Participants shared valuable experiences, including the establishment of bioenergy communities and the implementation of the first project for heat recovery from a sewage treatment plant in Thuringia.

The conference programme included presentations on the prospects and current developments for district heating in Germany and Thuringia, the role of large heat pumps, CO₂ networks as an alternative to water, wastewater heat utilization, and strategies to lower media temperatures in heat networks.

Speakers from Prognos AG, TWS GmbH, AGFW, Stadtwerke Energie Jena-Pößneck GmbH, Stadtwerke Schmölln, and Bioenergie Werratal eG contributed their expertise, offering insights into current challenges and opportunities in the regional and national heat transition.
