Temperatures measured 70 m to 100 m below the surface before and during BHE operation. The dashed lines show the temperatures measured with the DTS method before BHE operation and with a temperature probe in a nearby well (without BHE). The black squares show the TSM temperatures before BHE operation. The solid lines show the temperatures measured by DTS during BHE operation
