GREEN LOCAL HEATING WITH GEOTHERMAL HEATING
BASIC PRINCIPLE OF NEAR-SURFACE GEOTHERMAL ENERGY
The basic principle part 1
Development of heat sources in the ground with average temperatures of up to 12°C
Absorption of the heat by a suitable liquid (e.g. brine, blue dots), which is conducted into the earth via geothermal probes (pipe system).
Heated liquid (red dots) returns from the probes to the heat pump in the evaporator
The boreholes usually only go to a maximum depth of about 100 meters
The basic principle part 2
How does 12 degrees of geothermal energy in the heat pump become over 60 degrees of thermal heat?
