Six years of high-resolution monitoring data of 40 borehole heat exchangers

Description

Elisa Heim, Phillip Stoffel, Dirk Müller, and Norbert Klitzsch publish six years of close readings from a field of 40 borehole heat exchangers. These buried loops feed ground-source heat pumps that heat and cool buildings with high efficiency. In practice the systems often underperform, because design guesses drift from real conditions, and long records from working fields are rare.

Each of the 40 exchangers in this field carries its own sensors for flow and for inlet and outlet temperature, logged every 30 seconds across six years. Most past studies watched only the whole field's entry and exit points, hiding how single loops behave. The data set, published in 2024, should help researchers check models of loop behavior and design better systems. The authors present it as a public resource, the first of its kind at this detail.
