Wastewater heating potential Web-Application

The heating sector has been receiving more attention in the last years, as Europe's decarbonisation plans cannot succeed without focusing on the sector that represents almost half of its energy demand. Read more.

The tool estimates the heat potential of sewage water as heat source for large-scale heat pumps in a given city. It shows the district heating annual sales of the selected city as well as the environment benefits that the recovery of this heat source could provide. The tool was designed in such a way so that the user only needs to give a few input data for the calculation the calculation. The results are shown in a interactive map and with a graphs that allow a faster comprehension of the results.


Select the city you are interested for and introduce the requested input parameters. Note: If you are not familiarized with the requested data, please look at the suggested values in the help section (?) at the top right corner of the input and output panels

Input data

Choose the type of DH sytem


Low intensive CO2 DH network
Medium intensive CO2 DH network
High intensive CO2 DH network

Results

The results provided by this tool should raise awareness of how large-scale heat pump can recover heat from sewage systems and thus benefit district heating networks. It is expected, that the knowledge provided by this tool will facilitate cities and other stakeholders to take decisions about the development of heating technologies for district heating systems.

The tool should also provide the user with numbers and figures which could be useful when applying for grants for these technologies.
