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.
