Discover the differenceLower Your Footprint
~6 metric tons
Estimated CO₂ savings each year*
Geothermal draws warmth from the ground to heat your home without burning oil or propane.
Compared with oil heating and central A/C, that’s the CO₂ equivalent of about 15,000 miles of gasoline driving avoided every year.
Slash Your Energy Bill
Nearly 90%
Estimated energy-bill savings*
Geothermal, solar and battery storage work together to lower your home’s energy costs.
Generate your own electricity, store it for the evening and buy less from the grid.
Get Cozy
All year
Warm winters. Cool summers.
Geothermal delivers quieter operation than conventional air-source systems, drawing on stable ground temperatures through winter.
In summer, it cools your home and removes humidity, so rooms feel comfortable even when it’s hot and sticky outside.
About the estimates
Energy-bill savings. The nearly 90% figure is Silvermine Preserve’s estimate for the planned home-energy systems, not measured utility bills. Actual savings depend on home design, system sizing, solar production, energy use, weather and utility rates. Ask the Silvermine team for the assumptions applicable to your home.
Estimated geothermal carbon savings for Lot 13 compared with oil heating and central A/C, before solar. This separate carbon comparison uses the same house and heating/cooling demand for both systems.
| Annual estimate | Oil + A/C | Geothermal |
|---|---|---|
| Operational CO₂ | 7.18 metric tons | 0.88 metric tons |
Carbon model. Assumes a 4,900-square-foot home; annual useful heating/cooling demand of 80/25 million BTU; seasonal geothermal heating/cooling COP of 4/5; oil heating at 85% efficiency; and central A/C at SEER 15.
Carbon savings. Assumes 0.12 kg CO₂/kWh for grid electricity and 10.19 kg CO₂/gallon oil. The estimated reduction is 6.3 metric tons annually, rounded to about 6. EPA’s approximate gasoline-driving factor of 400 g CO₂/mile makes 6 metric tons equivalent to about 15,000 miles.
The carbon figures are modeled space-heating and cooling estimates, not measured performance or an installer forecast. They exclude solar and battery effects, hot water, pools, appliances, EVs, refrigerant leakage, upstream fuel emissions and manufacturing. Actual carbon savings depend on weather, use and the installed system. The carbon model does not establish the energy-bill savings percentage. Artwork illustrates the energy concept; equipment placement and underground layouts are conceptual.
Carbon sources: EIA fuel emissions, EPA grid data and EPA driving equivalence.
How geothermal works
Copper tubing beneath your property circulates refrigerant to exchange heat with the earth. In winter, the system brings that heat into your home. In summer, it reverses the process, moving heat out of your home and into the ground.
Direct exchange eliminates the separate water-and-antifreeze circuit used in conventional closed-loop geothermal. Geothermal moves existing heat rather than generating it through electric resistance, so it can deliver several units of heat for every unit of electricity it consumes.

How solar and storage work
Solar panels turn sunlight into electricity for your home. Battery storage saves energy for later use, including after sunset. Together, they reduce your reliance on electricity purchased from the grid.
For backup during an outage, the installed equipment, supported circuits and available battery charge determine what stays powered and for how long. The Silvermine team will walk you through your home’s configuration.
