A vertical geothermal heat pump system typically costs between $20,000 and $38,000. This range covers the full installation of the ground loop system and the indoor heat pump unit.
Geothermal Heat Pump Installation Costs by System Type
The total cost of a geothermal heat pump system varies significantly depending on the type of ground loop installation chosen. Vertical systems require less land area but involve deeper drilling, which contributes to their higher cost compared to some other options.
Here's a breakdown of average costs for different geothermal heat pump system types:
| System Type | Average Cost |
|---|---|
| Horizontal | $15,000 – $34,000 |
| Vertical | $20,000 – $38,000 |
| Pond / Lake | $10,000 – $32,000 |
| Open loop | $10,000 – $28,000 |
Costs are averages and can vary based on factors like home size, soil conditions, drilling depth, system efficiency, and local labor rates.
Understanding Vertical Geothermal Systems
Vertical geothermal systems are ideal for properties with limited land space or challenging soil conditions. The installation involves drilling several vertical boreholes, typically 150 to 400 feet deep, where U-shaped loops of pipe are inserted. These loops circulate a fluid that exchanges heat with the stable underground temperature. While the initial investment can be higher due to the drilling process, vertical systems offer excellent efficiency and a compact footprint.
