In addition to the solar park, a district heating network was built to supply the municipal buildings and residents with heat.
- Conducts heat to the buildings as required (including public buildings such as the community centre and kindergarten)
- Large hot water storage tank (buffer tank) ensures sufficient heat during the winter months and low solar radiation
- 200-kilowatt wood chip boiler for additional security in winter months
District heating network - Key figures
- 1.5 MWp (PV heat share) from the park
- Flow temperatures:
Summer 70°C / Winter 80°C - Return temperatures:
Summer 40°C / Winter 45°C - Approx. 1,000 megawatt hours:
of which approx. 70% from the park - 2 air heat pumps (121 kW each)
(base load only with PV yield) - Electric boiler (400 kW)
(power2heat for PV surplus/redundancy) - Wood chip boiler (200 kW)
(peak load and alternative operation) - Buffer storage tank (75,000 l)
(delivery capacity 24 hours at full load) - Direct power line (20kV)
