Premier2 Owner’s Manual

Is there more than one way

to install GeoExchange?

There are several different methods used to install a GeoExchange system. Your indepen-

dent WaterFurnace dealer will assist you in choosing the right one for your space. Our dealers

have been thoroughly trained on GeoExchange applications and are supported by the industry’s

best computer software to ensure that you receive the

right system.

Open loop systems

A GeoExchange open loop system uses ground water

as a direct energy source when good quality well water is

available at a reasonable pumping depth. A good water

discharge system is also required, such as a ditch, field

tile, pond or stream. An open loop system may require

periodic inspection/cleaning to prevent buildup of

mineral deposits.

Closed loop systems

The GeoExchange closed loop system is an underground network of sealed, high-strength

plastic pipe filled with a water/antifreeze solution. During cooling, heat is removed from the

building and dissipated into the cooler earth.  For heating, low-intensity heat energy is absorbed

from the earth, intensified, and delivered into the structure. A closed loop system uses a small,

low-wattage pump to circulate the liquid. Closed loops can be installed in the ground horizontally

in a trench, vertically in drilled holes or submerged in a pond or lake. All three are sealed airtight

and, when designed properly, produce similar efficiencies.
