Ground source heat pumps (GSHPs) mean attractive heating and cooling systems. The injection/extraction of thermal energy is obtained by borehole heat exchangers (BHE). Since the GSHP operates at a relatively stable temperature, the coefficient of performance of such systems is higher than that of air source heat pumps. BHEs are drilled to a depth <300 m with a diameter of 0.10-0.15 m. The proper BHE design requires knowledge of ground thermal properties. Thermal response testing (TRT) is used primarily for in situ determination of design data for BHEs. In current study, which was the first TRT in Syria, the purpose was to determine the effective ground thermal conductivity. Measured data were evaluated by the line source model. Used method and performed evaluation are presented for a borehole drilled in clay, silt and sand. The resulting effective ground thermal conductivity was 2.011 W/m.K and the borehole thermal resistance was 0.111 K /(W/m).
