In heating mode, the system circulates fluid in the loop system,
extracting heat from the ground. Heat is transferred to the
geothermal unit where it is compressed to a high temperature
then delivered through the home by a system of ductwork (forced
air) or a radiant heat system (hydronic).
For cooling, the process is simply reversed. Utilizing the cooler
temperature of the earth as opposed to the warm air above
ground, the TETCO geothermal system takes the heat from the
home and transfers it into the ground via the loop system.
