V17 — specialized system
Ground-source geothermal systems
Plan the heat pump, ground heat exchanger, drilling, site, groundwater and indoor distribution as one system.
Checked: 2026-08-22
Vertical/horizontal loops, wells or ponds have different site, drilling, environmental and permit constraints.
Drilling, underground loop, refrigerant or open-loop systems require specialized design/installation and local compliance.
Useful tools / data
- Load calculation
- Site/utility plan
- Loop temperature/flow history
What the professional checks
- Size field and heat pump to applicable CSA requirements
- Check geology/drilling and groundwater
- Commission flows, temperatures and controls
Sources and limits
Rules vary by jurisdiction and scope. Regulated, structural and gas work remains with the required professional.
V18
Specialized diagnostics to verify
V18 connects systems that become costly or regulated when a primary project triggers them.
