Welcome to the Support DHC Replication Hub!

This hub gathers a wide range of materials, including tools, guidelines, webinar recordings, presentations, deliverables, lessons learned, frontrunner case factsheets, and one-pagers. These valuable resources, developed and collected throughout the project, are designed to help you transform your DHC networks. Our goal is to share key insights from the project and inspire replication in other areas.

Below you can find 7 tools focusing on utilization of low temperature heat resources in high temperature DH networks.

The Toolbox offer tools and advices for a full heat planning process. It includes methodologies of mapping of low temperature heat resources (how to find them, how to estimate temperatures flow and variations over time), technology descriptions of high temperature heat pumps, a spreadsheet how to make pre-feasibility calculations and best and worst practise experiences from the Support DHC frontrunner cases and others. The Toolbox works as a manual for integration of low energy heat resources in high temperature district heating systems.

DHC transformation planning

The document summarises helpful tips, tried and tested ideas and procedures that address the creation of transformation plans (based on German funding guidelines). It essentially addresses the topics of actual state analysis, determination of potentials, targets, path to greenhouse gas neutrality and cost framework.
