Contact

Description

In principle, groundwater-operated heat pumps are possible throughout the city. One exception is the Waldtrudering water conservation area.

It should be noted that in the south of Munich the groundwater is relatively deep (15 to 25 metres) and in districts such as Solln or Großhadern there is very little groundwater in some areas.

We therefore recommend that you ask us about the groundwater levels at your location for reliable planning:
