Description of the project
The thermonet in Vridsloesemagle is planned to supply 75% of the 110 potential consumers. They will be continuously connected to the thermonet as their heating sources needs replacement. The thermonet is a part of the danish and swedish energyproject Smart Cities Accelerator+ (SCA+), which is supported by the EU regional fond Interreg Öresund-Kattegat-Skagerrak. The plan is for the district heating company of Høje Taastrup to supply the households through individual heat pumps, connected to the thermonet via branch pipes. The district heating company owns, establishes, operates and services the entire thermonet, and additionally disassembles and removes the previous heating source of the consumers. The expectation is fro the termonet to be able to supply 585 kW, while the heating demand is estimated to 475 kW, which leaves 20 percent of the capacity as a buffer.
Highlights of the project
Calculations demonstrated that it was possible to establish a district heating solution based on a fairly low number of initial customers compared to the traditional solution.
The biggest challenges / obstacles
Finding heatpumps that could be modified to include an energymeter that was approved for billing. General legislative issues.
