Annual Savings vs Current Annual Heating Cost
सूत्र
## 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.
हल किया गया उदाहरण
A home spending $2,500/year heating and $800/year cooling, switching from a furnace (COP 1) to geothermal (COP 4).
- 01Current total: $2,500 + $800 = $3,300/year
- 02Geothermal cost: $3,300 * 1 / 4 = $825/year
- 03Annual savings: $3,300 - $825 = $2,475
- 04Savings percentage: $2,475 / $3,300 = 75%
अक्सर पूछे जाने वाले प्रश्न
How much does a geothermal system cost?
Residential geothermal systems typically cost $15,000-30,000 installed. The federal tax credit covers 30%, bringing net cost to $10,500-21,000. They last 25-50 years.
What is COP in geothermal?
Coefficient of Performance (COP) measures heating efficiency. A COP of 4 means the system produces 4 units of heat per 1 unit of electricity consumed. Geothermal COPs range from 3-5.
Does geothermal work in cold climates?
Yes. Ground temperature below the frost line stays 45-75F year-round regardless of surface weather. Geothermal works well even in northern climates.
