Geothermal Savings Rechner — Formel
## How to Calculate Geothermal Savings
Geothermal heat pumps use stable underground temperatures to heat and cool your home much more efficiently than conventional systems.
### Formula
**Geothermal Cost = Current Cost * (Current Efficiency / Geothermal COP)**
**Savings = Current Cost - Geothermal Cost**
A geothermal system with a COP of 4 delivers 4 units of heating for every 1 unit of electricity, compared to a gas furnace at about 0.95 efficiency.

Lösungsbeispiel
A home spending $2,500/year heating and $800/year cooling, switching from a furnace (COP 1) to geothermal (COP 4).
- Current total: $2,500 + $800 = $3,300/year
- Geothermal cost: $3,300 * 1 / 4 = $825/year
- Annual savings: $3,300 - $825 = $2,475
- Savings percentage: $2,475 / $3,300 = 75%
