Inventory of geothermal systems
There are currently around 35 geothermal systems installed in the Brussels-Capital region. Most of these are closed shallow systems (geothermal loop fields). There are also 4 known open systems (geothermal wells). However, an inventory of small geothermal systems for single-family homes is difficult to compile, as no environmental notification is currently required in Brussels for low-output systems.
