There has been a large increase in greenhouse heating use in rural areas due to financial support for a special rural subsidy program. Recently, some private universities installed large heating systems without government subsidy in order to reduce operating costs of heating and cooling on campus. Geothermal or ground-source heat pump installation is rapidly increasing over the past four years, with a large increase in 2009, due again to an active rural subsidy program. Most installations in the country are mainly for office and public buildings and relatively large buildings such as dormitory, university campus and hospitals. Geothermal heat pumps are found in over 700 locations throughout the country and are typically in the 300 to 100 kW size for a total of over 3,000 units.

The various applications are:

8.66 MWt and 53.43 TJ/yr for individual space heating;
2.21 MWt and 31.28 TJ/yr for district heating;
0.17 MWt and 1.33 TJ/yr for greenhouse heating;
32.56 MWt and 507.61 TJ/yr for bathing and swimming;
185.7 MWt and 1,361 TJ/yr for geothermal heat pumps.

The total for the country is 229.3 MWt and 1,954.65 TJ/yr.
