The country is rich in geothermal water within the temperature range of 20 to 100oC with the main geothermal activity concentrated in the southern part of the country due to the higher water temperature and low water salinity. The information in the paper is based mainly on state-owned and only partially municipality-owned geothermal fields and is based on existing permits and concessions. The main geothermal direct-use in the country is for balneology (prevention, treatment and rehabilitation, bathing and swimming pools), space heating and air-conditioning, greenhouse heating, geothermal heat pumps, direct thermal water supply, bottling of potable water and soft drinks and for unspecified industrial use. The cultivation of microalgae and production of iodine paste and methane extraction have been terminated. The installed capacity for direct use, excluding geothermal heat pumps, is about 30% less as compared to five years ago.

The geothermal direct use is:

9.28 MWt and 128.56 TJ/yr for individual space heating,
6.7 MWt and 65.5 TJ/yr for air conditioning,
5.99 MWt and 88.68 TJ/yr for greenhouse heating,
48.78 MWt and 768.32 TJ/yr for bathing and swimming,
6.92 MWt and 32.83 TJ/yr for other uses (preparing steam for heat stations and public laundry),
20.63 MWt and 286.23 TJ/yr for geothermal heat pumps,

for a total of 98.30 MWt and 1,370.12 TJ/yr.
