<p>Geothermal energy probes, in particular at least a first group of two to five geothermal energy probes, are installed in the ground from a starting point in the radial direction such that the corresponding spreading angle between adjacent geothermal energy probes is at least 72° and the corresponding differential inclination angle is at least 10°, wherein the differential inclination angle continuously increases or decreases from one geothermal probe of the first group to the next.</p> |
