COMPACT CLOSED-LOOP DESIGN
Vertical Bore Geothermal Loops
Deep, narrow boreholes exchange heat with the earth while preserving most of the usable yard. The small surface footprint makes vertical loops a frequent retrofit choice.
GOOD STARTING FIT
Where this loop can make sense
Smaller lots, established landscaping, limited trench area, and projects where drilling access can be safely established.
Lease-program note
Vertical bore is one of the closed-loop types currently included in this site’s preliminary WaterFurnace PremiumPath screen. Final program eligibility still depends on equipment, engineering, property, credit, documentation and current PremiumPath/Palmetto rules.

INSTALLATION SEQUENCE
How the field comes together
- 01
A loop designer establishes required bore depth, bore count, spacing, fluid flow and circuiting from the building load, equipment and ground assumptions.
- 02
A licensed or qualified drilling contractor advances each bore, installs a factory U-bend pipe assembly, and completes the specified grout from bottom to top.
- 03
Headers connect the bores to the building. The field is flushed, purged and pressure-tested before final connection and commissioning.
PROS
- Small surface footprint
- Works on many retrofit lots
- Less broad excavation and restoration
- Stable long-term ground contact
TRADEOFFS
- Specialized drilling access and mobilization
- Subsurface uncertainty
- Higher drilling cost in difficult formations
- Bore logs, grout and pressure-test documentation are critical
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.
U-bend, grout and header work
Document materials and installation details before they are concealed.
Pressure test and restored site
Pair test evidence with a finished-yard view and final as-built notes.
Future project-photo standard: real installation photos will be added only after customer authorization is recorded and each image is checked for faces, plates, addresses and sensitive documents.
SITE VERIFICATION
Questions the field review must answer
- ✓ Rig access, overhead clearance and underground utilities
- ✓ Bedrock, unconsolidated material and groundwater conditions
- ✓ Required bore depth, spacing and setbacks
- ✓ Permits, drilling credentials, grout specification and spoils plan
