Geothermal heating and air conditioning systems tap into the Earth’s surface to use thermal energy found underground. When your goal is to find the most efficient heating and cooling systems available geothermal is your answer. Geothermal heat pumps are able to maintain very high efficiencies on even the coldest winter nights or the hottest summer days, all while saving energy and money. We offer both Bryant and WaterFurnace geothermal products to fit your needs.
When it comes to heating and cooling solutions, geothermal systems are extremely efficient. These packaged systems work quietly to deliver comfort in variable speed Preferred™ models or the multi-speed Legacy™ line. With the evaporator coil, condenser and compressor all in one cabinet, you can evenly heat or cool large homes easily.
Model | Heating Efficiency | Cooling Efficiency |
GB | 3.7 to 4.3 COP (closed loop); 4.3 to 5.2 COP (open loop) | 18.5 to 21.7 EER (closed loop); 21.4 to 28.1 EER (open loop) |
GP | 3.5 to 4.0 COP (closed loop); 4.0 to 4.6 COP (open loop) | 15.5 to 24.5 EER (closed loop); 19.6 to 30.0 EER (open loop) |
GC (Evolution) | 3.8 to 4.7 COP (closed loop); 4.5 to 5.2 COP (open loop) | 18.5 to 32.0 EER (closed loop); 23.1 to 37.0 EER (open loop) |
The Preferred™ Split System Geothermal Heat Pumps work best with a gas/propane furnace or fan coil. The quiet, efficient operation allows you to toggle between geothermal heating and gas heating for year-round comfort.
