The use of R744 expands the opportunity for geothermal heat pumps according to the presentation by Marc Portnoff, Thar Geothermal, LLC at ATMOsphere America 2014. R744 allows for a direct exchange design. By and large the R744 direct exchange geothermal heat pump is 30% more efficient than a standard ground source geothermal system, which tends to be 40-60% more efficient than an air side heat pump.
