Geothermal Drilling Methods
-
Open Loop: Uses your water well and pump to supply and return water to the aquifer. It’s a cost-effective solution but depends on the well’s water quality.
-
Closed Loop: Involves vertical well shafts with polyethylene tubing circulating glycol. It’s more expensive but “risk-free,” as it’s not reliant on water quality.
Which System is Right for You?
Your geothermal system choice depends on factors like the need for a water well, water production rate, and quality. Our team will help you choose the best system for your property.
