The 7 Series
With Variable Capacity Technology
The WaterFurnace 7 Series™ is quite possibly the most advanced heating and cooling system on the planet. It provides homeowners the ultimate in comfort and performance and represents our finest products. This line is for those who accept only the best and is built using the latest technologies and highest standards. Plus, with our OptiDry™ integrated reheat coil dehumidification technology, your system can provide whole-house humidity control without a separate, space-eating unit or subsequent additional wiring, electrical work, ductwork, or thermostats.
The 700A11 signifies groundbreaking innovations on multiple fronts—most notably as the geothermal industry’s first launched variable capacity residential unit and the only unit to surpass both the 43.5 EER and 5.1 COP efficiency barriers. These ratings are vastly greater than ordinary conditioning systems and 30% higher than current twostage geothermal heat pumps. The 700A11 is ENERGY STAR rated and was engineered in the HVAC industry’s only in-house EPA/ENERGY STAR Recognized Laboratory.
Using the earth to heat & cool
A geothermal heat pump (GHP) taps into the renewable solar energy stored in the ground to provide savings up to 70% on bills. Using a series of underground pipes, it exchanges heat with the earth instead of outdoor air. While air temperatures can vary greatly from day to night or winter to summer, the temperature just a few feet below the earth’s surface stays an average 55°-70°F year-round.
Summer cooling
As outdoor temperatures rise, a GHP collects the unwanted heat in your home and moves it to the cooler 55° earth. Meanwhile, ordinary heat pumps and air conditioners are forced to dump that heat outside. Unfortunately, hot summer air is already saturated with heat and is less willing to accept more. That makes ordinary cooling systems least efficient when you need them to be the most efficient.
Winter heating
As outdoor temperatures fall, a GHP draws from an underground reservoir of heat, concentrates it, and moves it to your home. Meanwhile, an ordinary heat pump is forced to collect heat from frigid winter air, making it least efficient when you need it to be the most efficient. And unlike a furnace, our units don’t create heat through combustion. They simply collect and move it.
Traditional Air Conditioner
Summer air is already saturated with heat and is less willing to accept more. Thanks to the constant temperature of the earth, geothermal is more than twice as efficient at cooling than any ordinary heat pump or air conditioner.
