Sdr. Felding, Denmark
The district heating company in Sdr. Felding has expanded their existing biomass-based production facilities with a large air to water CO2 heat pump at 3,3 MW, a huge buffer tank 3370 m2 (4,5 m3/consumer) and a 10MW electrical boiler. This visionary installation really shows the future of district heating, which will be smokefree and serve as an important player in balancing the electrical grid. It will absorb large amounts of green electricity when it is available and utilize the stored energy from the tank when the electricity supply is lower than the demand.
