Planning distances

Space requirement

The compact size of the geothermal basket requires up to 60% less space for the entire geothermal basket field than a comparable surface collector. For each geothermal basket should be about 35-40 m² area.

Installation in water protection areas

If no groundwater worthy of protection is tapped, installation is usually possible even in water protection areas under certain conditions. Even in water protection areas 3, permits (some with conditions) are usually issued for the installation of geothermal baskets.

Horticultural use

Shrubs, hedges or vegetable beds can be planted above a basket. For existing trees, pay attention to the tree canopy; baskets should not be installed below the tree canopy. Any regional requirements (tree protection) must be observed.

Overbuilding, pools or drive-over capability

The geothermal baskets may not be overbuilt with structures such as garages, carports, pools, basements or roads. The area above the installed BetaTherm geothermal baskets must not be sealed.

In the area of installed geothermal baskets, after 1 m of covering with soil, axle loads of 10 t can be driven over without danger.

We plan individually for your property


The geothermal baskets can usually be installed ready for connection within one day for a single-family house.

For this purpose, the baskets are sunk into 3.9 m deep excavations and backfilled with the existing soil or replacement material and compacted in layers. By means of modern connection technology, the baskets are connected centrally to our distributor. The primary line is led through the on-site house entry, where the installer makes the connection to the heat pump or heating circuit.
