Seeing a geothermal system at work. Includes the anatomy of a geothermal heat pump, basic concepts and descriptions of closed and open-loop systems.
Geothermal heat pump systems is fairly simple - all you need to know are a few basic concepts.
Anatomy of a Heat Pump
Instead of just producing heated or cooled air, a geothermal system moves heat from one place to another.
Open Loop Systems
An open loop system uses water direct from a surface or underground source - such as a pond, lake or well - instead of an antifreeze solution.
Closed Loop Systems
In a closed-loop system, the heat exchanger is a continuous loop of piping that is buried underground.
