WaterFurnace’s 7 Series geothermal heat pump surpasses both 41 EER and 5.3 Coefficient of Performance efficiencies. The unit utilizes a soft-start variable-capacity compressor, in concert with a variable-speed ECM blower and variable-speed loop pump. The 7 Series can ramp down to 20% of normal operation for ultra-efficient conditioning or up to 130% output using SuperBoost for periods when extra cooling is needed. The 7 Series uses Aurora controls to continuously monitor and optimize operation. The 7 Series 700A11 geothermal heat pump (pictured) was honored with a 2014 AHR Expo Innovation Award in the “heating” category.
