Styles of Geothermal Units
Closed Loop
In a closed loop system, ground source heat pumps work by circulating water or antifreeze solution through a closed loop of polyethylene pipe that is buried in the ground.
Open Loop
An open loop system involves taking water from the ground, using it as a heat source, and disposing of it on the earth’s surface. We are not proponents of this method, even though a number of people use it.
Standing Column
The standing column system is a great way to heat your home and conserve energy. Using a standard water well as a heat source, the geothermal unit extracts the heat from the water, which is recycled back to the well.
