By saying geothermal, do you mean digging 50-70 m holes and using geothermal energy, or you mean laying down pipes at 1.5 meter in the ground and using sun energy stored in ground?

First one could cost more than 20K and is the most efficient.

Second one costs 2K more that air-to-water system and is very efficient (but fractionally less than geothermal).

Comparisement between air-to-water and ground-source pretty much depends on location. If winter temperatures do not get bellow 5 degrees Celsious, air-to-water is most economical. Bellow that, ground source is better.
