| Member state | HUNGARY-1 |
| Case study | Hódmező-vásárhely |
| Description | Geothermal energy utilization in Hodmezovasarhely has decades of tradition. The first thermal well was drilled for balneology purpose in 1954. Another well was drilled for agriculture using in 1964. In 1967 a third well was drilled for a hospital : for therapeutic use and heating purposes. In 1993 the local government decided to develop an integrated geothermal district heating system. Around 2.800 flats ans 130 institutional consumers are provided with heating and hot water supply. |
