About this Service
Open loop geothermal ties an on-site well to a heat exchanger, using groundwater as the heat-transfer medium. In Centennial this approach can suit suburban estates and planned-unit developments that already have private wells or access to usable groundwater and that prefer to limit yard excavation.
Centennial’s Denver-basin clays and intermittent sand lenses affect bore and pump decisions. Sand lenses can carry abrasive material, so water testing must check sand content and silica levels. Filtration, sand traps, and corrosion control are common specifications. Balanced seasonal loads in Centennial mean designers size the system for both cooling peaks and winter heating, with attention to sustained GPM through seasonal drawdown. Discharge routing must be evaluated for erosion control and compliance with local authorities.
Operational expectations include scheduled filter changes, pump service, and occasional lab water checks. If well yield or discharge approvals are not attainable, a closed-loop alternative is recommended. The project deliverables include a site assessment, a water-treatment and discharge recommendation, an itemized equipment list, and a commissioning checklist covering expected flow and maintenance cadence.
