When it comes to district heating and excess heat there is a lot of knowledge, regulations and experiences that needs to be considered.


This ToolBox is a product of concrete experiences from the HEATflex project. The results from each workpackage and deliverable will serve as input for the online ToolBox. Moreover, the ToolBox contains research papers, examples, and other documents and information identified as being relevant for our target groups.

The roadmap will bring DH grid operators, planner and CHPs the innovative possibility to check the technical and economic feasibility by using simple input data. The output will be to assess feasibility, show possible technical solutions for implementation and planning, economic evaluation, as well as bus.

Guideline 1: Integration of waste heat and renewables

Guideline 2: Lowering grid temperatures

Guideline 3: Increase of grid efficiency and flexibility
