WaterFurnace’s new 7 Series variable-capacity geothermal system surpasses both 41 EER and 5.3 COP. The 700A11 (pictured) uses WaterFurnace’s InfiniSpeed technology, a soft-start variable-capacity compressor, in concert with a variable-speed ECM blower and variable-speed loop pump. This allows the unit to scale output to exactly the level needed - it 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.www.waterfurnace.com
