This paper presents a summary of the results of various thermal response tests performed on nine adjacent 80-m-deep boreholes. Over forty tests with durations between 48 and 320 hours have been performed during the last 3 years. All nine boreholes were tested under similar conditions to check random uncertainties between tests. Several tests with diverse conditions were then performed to study sensitivity of test results to test variables and to quantify uncertainty in test results. Some of the tests were also repeated to ascertain reproducibility of the results. The paper also presents experimental measurements of borehole annulus temperatures during a test and recovery times of boreholes after a test.
