Field measurement results
No estimates — documented measurement data from multiple reference projects.
35 % higher heat extraction enables shorter boreholes at the same extraction capacity — decisive where regulatory depth limits apply.
10 concentric outer pipes create a 30–35 % larger contact area with the ground — within identical borehole geometry.
Advantage per 100 m borehole compared to a double-U-tube probe at equivalent thermal performance — a relevant margin in series production.

Simulation results of a 25×4 probe fieldBLZ Geotechnik GmbH / TU Freiberg / Transflow GmbH.
673.3 MWh/a vs. 507.1 MWh/a for double-U — +33 % more annual energy over the entire simulation period.
Combined seasonal coefficient of performance with regeneration. Pure heating SCOP is comparable (4.14 vs. 4.16) — the advantage lies in capacity.
Cooling capacity 287.7 kW vs. 220.9 kW — the enlarged surface works bidirectionally: more extraction in winter, better regeneration in summer.
