In the area (37.55 N, 126˚84 E) to get the data for the design and heating performances of heat pump for water to water system, the experiments were run. The vertical-closed loop ground source heat exchanger was installed under the 150m of ground from surface. The temperature, flow rate and electric power was measured. Released heat was 17,989.91kcal/h, used electric power 4,71kW/h and COP 4.44, and the average out side temperature was -8.64℃. Also the capacity of water was sufficient for supply ing the heating system.
