The result is a new performance level:

Efficiency on Every Square Metre

Our technology optimises the area potential of available space and enables economic solutions even where limited space or depth restrictions previously posed obstacles. This makes thermal development particularly attractive in challenging site conditions or complex probe fields.

With up to 35 % increased heat extraction, the Multi-U-Tube Probe consistently exploits the geological reservoir and minimises untapped energy potential. This gives our technology the decisive lever to implement geothermal projects both economically viable and technically future-proof.

Target Segments with Highest Relevance

Space-constrained Projects

Inner-city developments, narrow plots, dense construction. Fewer boreholes at the same performance — direct cost impact.

Fewer boreholes, same performance

Depth Permit Restrictions

Depending on the location, borehole depth restrictions may apply (e.g. groundwater protection). Where conventional probes reach their limits, the MU probe can deliver sufficient performance to make geothermal energy a viable alternative.

Large Installations & Districts

Multi-family buildings, commercial properties, district solutions. Scale effects and series production pay off directly in large orders.

Scale effects immediately effective

Retrofit & Modernisation

Existing geothermal systems with suboptimal performance can be upgraded through MU probe retrofitting.

Tender Relevance

The EU Energy Efficiency Directive and national funding programmes increasingly tie into efficiency classes. The Multi-U-Tube Probe with documented performance advantages meets higher efficiency classes — a measurable advantage in public tenders.

Efficiency Advantage

The market for borehole heat exchangers is today largely standardised around double-U-tube probes. The MU probe offers a documented innovation with measurable advantages — in a market segment that actively seeks efficiency improvements.

Example Scenarios

Residential quarter, 10,000 m² NFA, ~600 MWh/a heat demand

Conventional

DU-100 (25×4 with regen.): 507 MWh/a — demand not covered, additional boreholes required

MU probe

MU-100 (25×4 with regen.): 673 MWh/a — demand covered + reserve. Source: 100y simulation.

Multi-family building, 6 boreholes at 100 m planned

Conventional

6 × 100 m double-U = standard design

MU probe

5 × 100 m MU probe = same total performance — 1 borehole saved

Commercial property with cooling demand

Conventional

DU-100: 220.9 kW cooling capacity (sim.)

MU probe

MU-100: 287.7 kW cooling capacity — +30 % for increasing cooling loads (sim.)
