What We Do

Open loop installation that helps Home Owners use groundwater wells for heating and cooling

Covering well pump integration, filtration and water treatment, discharge routing, and heat exchanger connections.

  • Well Pump Integration & Filtration

    Integrate well pump, install filtration, and configure flow controls to protect exchangers and ensure steady flow.

  • Discharge & Heat Exchanger Connection

    Route discharge, connect to the heat exchanger, and run performance checks and compliance verification.

Why Denver Geothermal

Site-specific open-loop planning with itemized cost breakdowns

Open loop installs hinge on well water quality, pump integration, and discharge options; wrong choices raise ongoing costs and permit risks.

Common Challenges

  • Poor well water quality needing treatment

    High mineral or sediment loads can foul heat exchangers, increase filter replacements, and raise ongoing maintenance costs if untreated.

  • Discharge permitting and regulatory hurdles

    Arapahoe County discharge rules and routing limits can delay installs; unresolved permits may cause fines and project rework.

  • Well pump integration and reliability concerns

    Incorrect pump sizing or missing controls causes low flow, reduced efficiency, frequent trips, and premature component wear.

How We Help

  • Lower energy use with open-loop systems

    Open loop installs using adequate well flow commonly cut heating and cooling energy use by up to 30% versus older systems.

  • Filtration and water-treatment planning

    We specify filtration media, cartridge types, and replacement intervals tailored to your groundwater chemistry to protect exchangers.

  • Permitting and discharge planning included

    We prepare discharge routing and permit packages aligned with local rules to reduce approval delays and avoid fines.

  • Proper pump sizing and controls

    Pump integration includes sizing, variable-speed controls, and flow monitoring to maintain rated flow and steady heat exchange.

Who We Help

Property owners with wells seeking lower HVAC costs

  • Homeowners with existing wells and yard space

    Centennial two-stories and suburban estates with private wells that want a lower-running-cost alternative without extensive closed-loop excavation.

  • Suburban estates and planned community owners

    Owners in planned unit developments near Highlands Ranch edge or Dry Creek Basin who prefer less yard disruption and clear loop options.

  • Developers and builders planning loop options

    Local developers who need itemized loop costs, loop-type comparisons, and soil-fit guidance for Centennial home builds.

How We Work

How Open Loop Installation Works

From site assessment to commissioning checks, we plan, document, and arrange installation with clear specifications.

  1. Site assessment

    We test well flow and water quality, review yard and soil constraints, and report on open-loop feasibility and recommended sizing.

  2. Design & permit

    We specify pump, filtration, heat-exchanger tie-ins, draft discharge routing, and prepare permit documentation for Arapahoe County as needed.

  3. Install & commission

    We arrange installation, tie pumps and exchangers, perform commissioning checks, and verify performance and compliant discharge routing.

About This Service

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.

Frequently Asked Questions

Common questions about open loop systems in Centennial

Answers on water quality, permitting, timelines, and maintenance to help you decide with local facts.

Untreated water can foul heat exchangers, clog filters, and cause repeated service. Early water treatment prevents frequent replacements and higher operating costs.
Delaying permits can halt work, require re-routing discharge, and lead to fines. Preparing permit packages upfront avoids costly schedule slips and rework.
Many open loop discharges require county approval. We prepare routing plans and paperwork to meet Arapahoe County standards and streamline approvals.
From site assessment to commissioning typically 4–8 weeks depending on permits and well work. On-site hookup and commissioning often take 2–4 days.
Filter intervals depend on water quality; expect cartridge or media service every 3–12 months. We specify intervals after initial water testing.
If designed to your well's sustained yield with proper flow controls, an open loop avoids depletion. We assess capacity and size systems to protect groundwater.
