Abstract: FIELD: power industry. 
     SUBSTANCE: an installation has been proposed for determination the subsoil rocks temperatures change rates, which contains first sample 1, including first model of subsoil rocks 2, made in the form of a cylinder of radius R 1 and covered with thermal insulation 3. On the outer surface of first subsurface rock model 2, first electric heater 4 is disposed, and a first tube 5 of radius r 1  is installed coaxially inside. In the middle section of first model of subsoil rocks 2, first thermocouple 6 located on its outer surface is radially installed, second thermocouple 7 located on the surface of first tube 5, and also third 8, fourth 9 and fifth 10 thermocouples located between first 6 and second 7 thermocouples. The sixth thermocouple 11 is located on the surface of first tube 5 symmetrically with second thermocouple 7. The inlet of first tube 5 is connected by a supply line 12 with a reservoir 13 for a heat transfer fluid 14 covered with a thermal insulation 15 and connected by a filling pipe 16 on which first tap 17 is installed with a cold water supply system. An electric heater 18, a lower level sensor 19, an upper level sensor 20 and a temperature sensor 21 are disposed in container 13. On supply line 12, a pump 22, a first tee 23, a second tap 24 and an inlet temperature sensor 25 are installed in series along the direction of movement of heat transfer fluid 14. Free branch of first tee 23 is connected by a bypass conduit 26 on which third tap 27 is mounted, with a capacity of 13. The unit for determination the subsoil rocks temperatures change rates contains at least one additional sample 28, identical to first sample 1 and containing a second subsoil model 29 in the form of a cylinder of radius R 2  and covered with thermal insulation 30. On the outer surface of second subsurface rock model 29, a second electric heater 31 is disposed, and a second tube 32 of radius r 2 , input of second tube 32 being connected by an intermediate conduit 33 on which an intermediate temperature sensor 34 is mounted, with the output of first tube 5. A seventh thermocouple 35 located on its outer surface, an eighth thermocouple 36 disposed on the surface of second tube 32, and also a ninth 37, a tenth 38 and an eleventh 39 thermocouple located between seventh 35 and eighth 36 thermocouples are installed in the middle section of second subsoil model 29. Twelfth thermocouple 40 is positioned on the surface of second tube 32 symmetrically with eighth thermocouple 36. The output of second conduit 32 is connected to reservoir 13 by a return conduit 41 with a temperature sensor 42, a second tee 43 and a fourth tap 44 installed in succession in the direction of movement of heat transfer fluid 14, a drainage line 45 connected to the free branch of second tee 43, on which a fifth crane 46 is installed. In this case, a third tee 47, a sixth tap 48 and a fourth tee 49 are arranged in series on return line 41 between the output of second tube 32 and output temperature sensor 42 sequentially in the direction of movement of heat transfer fluid 14. A connecting-supply conduit 50 is connected to the free branch of third tee 47, on which seventh valve 51 is installed, a connecting-return conduit 52 is connected to the free branch of fourth tee 49, on which eighth valve 53 is mounted. 
     EFFECT: expansion of the field of application of the known installation due to the increase in the range of measurements of the subsoil rocks temperature and an increase in the accuracy of determination the subsoil rocks temperatures change rates.
