3. Distribution System
The Ground Loop Heat Exchanger
The ground loop is the interface with the earth that transfers energy via a freeze-resistant solution pumped through the exchanger at a high velocity. Several ground loop types and designs are available to match the unique properties of each project. Learn more here.
The Ground Source Heat Pump
The ground source heat pump utilizes a refrigeration circuit to extract thermal energy from the ground loop and transfer it to the distribution system during the winter months to warm the home. During the summer, this process is reversed to cool the home.
The Distribution System
The distribution system quietly delivers heat throughout the home, creating a very even and controlled temperature. Air-based systems use duct work, while radiant flooring or fan coils distribute heat with a water-based hydronic system.
How do you know which system is right for you? That depends on your situation. Read our article on the four basic geothermal system loop types to help you decide.
