The deepest geothermal heat well in Finland is 1600 m deep

At Lounavoima, climate values and sustainably produced energy guide all operations. QHeat’s heat well reduces energy waste and cuts the use of fossil fuels. In 2021, the deepest heat well in Finland was built for Lounavoima Oy. The depth of the heat well is 1600 meters and it will be connected to the heating plant as a seasonal storage facility.

The project continues in 2023 and the final target is to complete 6 deep geothermal heat wells to provide clean heating energy to the district heat network.
