The aim of the geothermal investment in Mosonmagyaróvár was to develop a system that can almost completely replace the boilers of the existing district heating system and cover ~85% of the total annual heat production from geothermal sources. The investment includes the construction of a production well and a recovery well, with a connecting piping system and a geothermal heat exchange. Through this the geothermal system can be connected to the municipal district heating network. Arctic Green Engineering Services Ltd. (formerly Mannvit Ltd.) carried out the execution design and full permitting procedures for the system and provided technical supervision services for the well drilling preparation works.
