Geothermal heat pump from WaterFurnace
WaterFurnace’s 3 Series 300A11 geothermal heat pump offers efficiencies up to 22.3 EER and 4.1 COP. The series features Copeland UltraTech two-stage scroll compressors and five-speed ECM blowers. It comes standard with durable, all-aluminum air coils. It can be used in conjunction with the IntelliZone2 24-volt zoning system to precisely control the temperature in up to four zones. An optional soft starter — IntelliStart — reduces startup amperage by up to 60% of normal draw and reduces noise, eliminates light flicker and increases compressor life. All models are Energy Star rated and utilize ozone-safe R410A refrigerant that meets stringent EPA requirements.
