Geothermal Pump System
Liquid is circulated through a "close-loop" of tubes buried outside the building and then is exchanged in 7 "ground-source" heat pumps in the building that raise the pressure and temperature of the refrigerant liquid. This heat is exchanged with a separate internal water loop and circulated in the floor to heat the interior. The process is reversed for summer cooling.
