GROUNDWATER-BASED DESIGN
Open-Loop Geothermal Systems
An open-loop system moves groundwater through the heat pump and discharges it through an approved method. Water quantity, quality and legal discharge are core design inputs—not afterthoughts.
GOOD STARTING FIT
Where this loop can make sense
Properties with verified sustainable groundwater yield, acceptable water chemistry, a legal discharge approach and an owner prepared for water-side maintenance.
Open-loop systems are not currently included in PremiumPath. West Jefferson Plumbing and Heating can still design and install a qualifying open-loop project using cash purchase or traditional financing, subject to well, water-quality, discharge, engineering and lender review.

A simplified, not-to-scale supply-and-return-well concept. It is not a well design, proof of water availability, discharge approval or a West Jefferson jobsite photo.
INSTALLATION SEQUENCE
How the field comes together
- 01
A qualified well professional verifies the source, pumping level, sustainable yield and water chemistry under realistic operating conditions.
- 02
Groundwater passes through the geothermal heat exchanger at the manufacturer’s required flow and pressure.
- 03
Used water is discharged to an approved return well, surface location or other permitted destination without erosion, icing or resource conflicts.
PROS
- Can deliver strong heat-transfer performance
- No buried closed-loop field
- Existing well information may support early screening
- Potentially smaller installation footprint
TRADEOFFS
- Depends on sustained water yield and pump energy
- Minerals, sediment, corrosion or fouling can require maintenance
- Discharge and permitting can be decisive
- Nearby records do not prove conditions on the property
FIELD DOCUMENTATION
What our team documents during installation
A useful project record shows the parts of the loop installation that affect access, performance, restoration and future service. These are the field views we document for this loop type.
Document pumps, filtration, isolation, flow control and service access.
Show the legal destination, erosion protection and winter-condition planning.
SITE VERIFICATION
Questions the field review must answer
- ✓ Pump test, static and pumping water levels
- ✓ Water chemistry, filtration and heat-exchanger compatibility
- ✓ Well ownership, setbacks, permits and discharge legality
- ✓ Freeze, erosion, icing, return-well and long-term maintenance plan
