Bryant GW Geothermal Heat Pump.

Exceptional Comfort and Fuel Economy with Your Water-Based System

The versatile Bryant GW model can be applied in a variety of heated- and chilled-water applications. A two-stage scroll compressor enables high energy efficiency with quiet operation, plus optional potable hot water generation can also help you save on water heating for other needs.

  • EER Efficiency Range: 14.6 to 22.1 EER (closed loop); 18.8 to 25.7 EER (open loop)
  • COP Efficiency Range: 3.0 to 3.2 COP (closed loop); 3.4 to 3.8 COP (open loop)
  • Compressor Type: Two-Stage


  • Manage your utility costs with high-efficiency comfort (efficiency is unit size dependent): Closed loop cooling EER – Up to 22.1; Closed loop heating COP – Up to 3.2
