Geothermal response test on an already installed borehole heat exchanger (BHE):
> connecting the measuring device to the prepared BHE and removing the air from the system
> starting the test
> test duration: approximately 48 hours
> disconnecting the measuring device from the BHE
>taking 4 recordings of the temperature profile for the whole depth:
one before the test, followed by 1, 2 and 3 hours after the test has finished

Evaluation of the test results with the GeRT-CAL-2-0-10 software]
> determining the thermal conductivity [] of the soil
> determining the borehole thermal resistance
> evaluating and interpreting the temperature profile with depth
