Heat Supply from Estonia's Deepest Geothermal Borehole
The Geological Survey of Estonia has initiated heat supply from a 712.5-meter deep borehole in Arbavere, Estonia, marking the country's deepest thermal borehole.
Located in Lääne-Viru County's village of Arbevere, this borehole provides heating and cooling to the Geological Survey's research center buildings.
The Arbavere pilot project features a coaxial pipe, a first in Estonia, where water flows through the pipe's center, passes through a heat exchanger, and is then reinjected through the annular space.
- The borehole's thermal capacity is 40 kW.
- Three geothermal heat pumps are installed to increase the temperature.
- A cooling system is installed in one building.
