1 Answer 1


A ground-source heat pump is not a form of geothermal energy at all.


  1. energy source is underground natural nuclear reactions;
  2. source temperature is over 50°C;
  3. Energy is extracted with passive heat exchangers.

Ground-source heat pumps:

  1. energy source is solar radiation;
  2. source temperature is about the same as annual average air temperature;
  3. Energy is extracted using active technology, compressing and expanding fluids to lift the temperatures to something useful.
  • I see. Ground-source heat pump is not exactly a form of Geothermal energy Nov 18, 2015 at 7:50
