| Member state | ROMANIA |
| Case study | DISTRICT HEATING SYSTEMS IN ORADEA: Iosia nord |
| Description | The geothermal heatplant was designed to supply the secondary fluid (treated water) with a temperature of 102°C , which can provide 80% of the heat demand for space heating at the design value of -15°C outer temperature , and 100% for house hot water. The peak load for space heating is supplied by two natural gas fired boilers, which increasethe supply temperature of the secondary fluid from 102°C to 110°C. |
| Region>City>location | Oradea, Romania |
| Installed capacity ( MWth) |
24,2 |
| Installed geothermal capacity | 19 |
| Inhabitants connected | 3000 flats, 8000 people |
| Operating Temperature of the DH | 90°C |
| Temperature of the geothermal ressource (production – injection) |
104°c |
| Production of heating and/or cooling | 24 GWh/y |
| Others uses (drinking water, cascade uses…) |
In 2012, a 50 kW demonstration ORC power plant was installed to complete the heating plant, being the first operational geothermal electric generation plant in Romania. Space and greenhouse heating, domestic hot water supply, process heat, balneology and swimming pool. During summer, when the heat depleted geothermal water has a constant low temperature , it is partly used for the Iosia Swimming Pool , the rest being reinjected |
| Comparison with fossil energies | Since 2005 a geothermal heating plant has been operating in the city’s Iosia district, replacing 115.000 GJ/year of lignite and natural gas which is used at the existing CHP. |
