Heat Roadmap Europe 1 was developed to understand if the approach from Heat Plan Denmark could be extended to a European scale, and if it was possible to make a geographic and system analysis of the European heating sector, in addition to introducing the idea that district heating could play a significant role in decarbonising the EU energy system, as well as suppressing

The main outcomes were a validation of the potential district heating had in reducing costs, primary energy supply, integrating renewables, and creating a local economy for energy. Additionally, HRE1 allowed for the validation of the methodology, and the identification of improvements in the data and methodological processes.
