Equipment of the Month for November 2012: WaterFurnace 7 Series Geothermal System

WaterFurnace 7Series Geothermal Heat PumpToday we are introducing the WaterFurnace 7 Series Geothermal System. According to the WaterFurnace website this system is “the best of the best. Variable capacity system delivers comfort and savings you have to experience to believe.”

And two more quotes from the WaterFurnace website:

“The WaterFurnace 7 Series™ 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. The 700A11 signifies groundbreaking innovations on multiple fronts – most notably as the geothermal industry’s first fully launched variable capacity residential unit and the only unit to surpass both the 41.0 EER and 5.3 COP efficiency barriers. These ratings are vastly greater than ordinary conditioning systems and 30% higher than current two-stage geothermal heat pumps.”

“Our Aurora communicating controls work in unison with the InfiniSpeed technology. A variable capacity compressor, variable speed loop pump, and variable speed blower motor combine to offer a level of comfort you have to experience to believe. Best of all, 7 Series units use the stored energy in your yard to provide savings up to 70% on heating, cooling, and hot water.”

Looking at the efficiency values, 41 EER (energy efficincy ratio) and 5.3 COP (Coefficient of Performance), this system provides double the efficiency than the simpler Versatec Ultra and Legend systems. We need to understand however that these efficiencies vallue are depending on factors such as geothermal loop layout, equipment size and actual load, and will not be achieved under all conditions.

What features make the Series 7 so much more effective than other geothermal systems?
Let’s take a look at some of the key features:

Variable Capacity Compressor, realized through speed control.
This also allows for soft start capability what prevents wear and tear and allows for much lower lower peak currents.

Variable Speed Blower Motor realized utilizing ECM motors. The blower motor runs at only the speed needed for maximum efficiency and savings.
With Active Dehumidification enabled Aurora Controls optimizes the blower to maximize moisture removal.

– Aurora Controls, the advanced control unit, offers full two way communication between components, advanced operating logic and robust troubleshooting capabilities.
It supports true energy monitoring, extended hot water generation control and integration with WaterFurnace’s IntelliZone2 zoning system.

Coated Air Coil, FormiShield™ Plus, resists corrosion and increases lifespan. Its patented “11 element” fin technology and large size improves efficiency and
dehumidification during cooling.

– Optional Hot Water Generation – With an optional hot water assist, the 7 Series preheats water and delivers it to the water heater.
A sophisticated microcontroller monitors heat pump conditions and determines when there is excess heat available to route to the hot water heater.

Carolina Heating Service is a Water Furnace GEOPRO Master DeaklerTo summarize, it’s the sum of latest technology components controlled by WaterFurnace’s Aurora Controls what make the
7 Series an outstanding and state of the art heating and air conditioning system.
