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.

Examples of EnergyPRO calculations

This Support DHC energyPRO Excel calculation tool provides an economic feasibility assessment of electric heat pumps in existing district heating networks, where such pumps are needed to utilise low-temperature sources in DH systems. Its purpose is to evaluate the cost-effectiveness and feasibility of heat pumps compared with other decarbonisation technologies.

Report

Integration of Renewable Energy Sources into Existing District Heating and Cooling Systems

DHC offers an efficient and flexible, organisational and technical solution for the energy transition in the heating and cooling sector. It provides a broad platform and a major lever for the integration of all kinds of renewable energy sources. The research of Annex TS5 has investigated and evaluated the state-of-the-art and best practices at the international level for introducing RES into existing large urban DHC systems and thus transforming and decarbonising their heat supply.

Paper

Decarbonizing a Polish district heating network using ambient and waste heat: a techno-economic analysis considering uncertainties in future energy prices and availability

This paper presents a techno-economic analysis for a decarbonized DH network for a city in Poland, using a simulation model that evaluates levelized cost of heat (LCOH) across a wide range of heat supply portfolios including AH and WH sources. It considers uncertainties related to energy price and WH cessation scenarios as well as sensitivities related to WH prices, heat demand, and biomass availability.
