In addition to these large installations, there are numerous small- and medium-size geothermal heat pump units located throughout the country. Under the prevailing economic and political conditions, multiple or cascaded uses are employed to help improve the economic efficiency of the direct use. For this reason many installations combine district or space heating with greenhouses and thermal spas. No numbers are given for greenhouse heating. Geothermal heat pump installations are difficult to determine, however, estimates from sales statistics indicated that there are 148,000 units operating in 2008 and a 20% increase estimated for 2009 for a total of 178,000 units (13% water-source and 87% ground-coupled).

The capacity and energy use for the various applications are:

1.2 MWt and 2.9 TJ/yr for individual space heating,
209.3 MWt and 1054.4 TJ/yr for district heating;
44.9 MWt and 1,339.2 TJ/yr for bathing and swimming;
2,230 MWt and 10,368 TJ/yr for geothermal heat pumps,

for a country total of 2,485.4 MWt and 12,764.5 TJ/yr.
