Heat Supply from Estonia's Deepest Geothermal Borehole
The Geological Survey of Estonia has commenced heat supply from a 712.5-meter borehole in Arbavere, Estonia, marking the country's deepest thermal borehole.
The borehole, located in Lääne-Viru County's Arbevere village, utilizes a coaxial pipe architecture - a first in Estonia. This design features water flowing through the pipe's center, then passing through a heat exchanger before being reinjected via the annular space.
- Borehole depth: 712.5 meters
- Thermal capacity: 40 kW
- Three geothermal heat pumps installed
- Cooling system installed in one building
