A ground-source heat pump is not a form of geothermal energy at all.
Geothermal:
- energy source is underground natural nuclear reactions;
- source temperature is over 50°C;
- Energy is extracted with passive heat exchangers.
Ground-source heat pumps:
- energy source is solar radiation;
- source temperature is about the same as annual average air temperature;
- 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 Commented Nov 18, 2015 at 7:50
