Vrt FGB-1

FGB-1 is a thermal production well in the Pannonian Basin geothermal field of Hungary or the border region, where a borehole tapping the deep bicarbonate-rich geothermal aquifer supplies thermal water at elevated temperature for a spa facility or thermal bathing complex. Hungary's modern thermal industry relies extensively on deep geothermal wells like this one, which can tap water at 50-100°C from depths of hundreds to thousands of metres beneath the Pannonian plain. The extraordinary productivity of the Pannonian geothermal system — which powers over 1,300 thermal facilities across Hungary and neighbouring countries — makes deep thermal wells like FGB-1 the foundation of Central Europe's most developed geothermal bathing culture.
