Klina is a hospital located in Antwerps, during it's expansion they opted for a Terra energy geothermal plant. This heating and cooling plant uses an aquifer thermal energy system to withdraw the energy from the subsoil.

During the winter months ground water is pumped from the aquifer to a heat pump, this heat pump will extract the heat from this ground water through a heat exchanger. So the actual ground water is not used in the heating lines. The ground water from the "warm" well is cooled by this process and is reinjected into the aquifer using the second "cold" well (see also technology for further information).

During the summer months the process is inverted. Providing the system with cool ground water from the cold well.

By investing in this technology Klina saves 69% on its heating bill and saves 76% on its cooling energy.

Apart from the obvious economical savings realised, the Klina hospital now also reduced it's carbon footprint with 207 tons of CO_² every year!
