Endorsements don’t get better than this! We installed a variable-capacity unit from WaterFurnace’s new 7 Series in Sean’s grandmother house. Later, we asked what she thought.
She said she was quite comfortable but … she could no longer hear whether the furnace was running! This very quiet and efficient system was doing its job!
The unit, 700A11, presents ground-breaking innovations on several fronts:
- It is the geothermal industry’s first fully launched variable-capacity residential unit.
- It is the only unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers. These ratings are vastly superior to ordinary conditioning systems and 20% higher than current two-stage geothermal heat pumps.
The unit is at 20% capacity when it engages and has multiple levels as it ramps up. The traditional two-stage units are at 70% capacity when they start up. The new unit has Aurora communicating controls working in unison with InfiniSpeed technology. A variable-capacity compressor, variable-speed loop pump, and variable-speed blower motor combine to offer the high level of comfort experienced. Best of all, 7 Series units use the stored energy in a person’s yard to provide savings up to 70% on heating, cooling and hot water.
