Some geothermal pumps can actually be combined with solar heating to form a geosolar system and can enjoy even higher efficiency. Interestingly, this form of pump was first created in 1852 and physically realized in 1940. Manufacturers of geothermal heat pumps include companies like Addison, ClimateMaster, Econar, McQuay Enfinity and Rheem. The Rheem Prestige Series? RPRL- JEZ Two-Stage operates at 17 SEER and 9.50 HSPF. It also uses earth-friendly refrigerant. While these systems are naturally based heating pumps, some models like the Econar GeoSource 2000 Forced Air, still have electrical controls. If you can afford the high setup costs, this may prove to be an efficient system for you.
