The ground temperature stays constant at ~10 °C, so efficiency does not drop in cold weather.
All-indoor installation in the technical room — no permits, no neighbour-noise discussion, ideal for listed buildings.
Highest ErP rating thanks to the constant temperature of the ground source.
The borehole loop typically outlives several heat pumps. The investment lasts a generation.
Suits detached homes with a garden of at least 200 m² (horizontal loop) or with permission for a vertical borehole (75–150 m). Ideal for new-build and deep renovations where you can plan the source up front.
Not suitable for terraced homes without garden space, or for situations where the upfront investment cannot be amortised over the long service life. An air-source Altherma 4 H is then the better fit.

Typically 75–150 m for a vertical loop. The exact depth depends on the soil composition and the heat demand of the home. A site survey delivers the definitive sizing.
Yes, provided the garden has space for the drilling rig (~3 × 3 m around the borehole). Retrofit costs are higher than for new-build because the heat-distribution system usually has to be checked too.
Ground-source heat pumps qualify for a higher ISDE bracket — typically €4,000 to €5,500 depending on capacity and SCOP. We coordinate the application with your installer.
