WaterFurnace has launched the 7 Series, which the company said represents breakthroughs in energy efficiency, integrated technologies, communication capabilities, and comfort. WaterFurnace said the 7 Series 700A11 is the first variable capacity geothermal unit available for homeowners and the only unit to surpass both 41 energy efficiency ratio (EER) and 5.3 coefficient of performance (COP). This represents efficiencies twice that of traditional air conditioners or heat pumps and 30 percent greater than current geothermal units.
