What is the depth range for installing a horizontal loop geothermal system?

The appropriate depth range for installing a horizontal loop geothermal system is typically between 6 to 9 feet. This depth is critical because it allows the system to effectively absorb heat from the ground, which maintains a more stable temperature year-round. At this depth, the soil is less affected by seasonal temperature fluctuations, enabling the system to operate efficiently.

The correct depth ensures that the loops are sufficiently buried to access the geothermal energy while also being shallow enough to minimize excavation costs and installation complexity. The selected range takes into account factors such as soil type, moisture content, and local climate conditions, which can influence the system's overall efficiency and performance.
