Heat Pump vs Gas Furnace Calculation Guide
Follow this step-by-step method to calculate heating costs manually:
Step 1: Calculate heating demand
Example: 2,000 sq ft × 30 BTU = 60,000 BTU/hr
Step 2: Convert BTU to energy use
For heat pump:
Example: 60,000 ÷ (3 × 3,412) = 5.86 kWh
Step 3: Calculate electricity cost
Example: 5.86 × $0.12 = $0.70 per hour
Step 4: Calculate gas furnace consumption
Example: 60,000 ÷ (0.90 × 100,000) = 0.67 therms
Step 5: Calculate gas cost
Example: 0.67 × $1.20 = $0.80 per hour
Step 6: Compare results
- Heat pump cost: $0.70/hour
- Gas furnace cost: $0.80/hour
- Result: Heat pump is cheaper in this case.

| System Type | Efficiency | Energy Type | Cost per Unit | Hourly Cost |
|---|---|---|---|---|
| Heat Pump | COP 2.5 | Electricity | $0.10/kWh | $0.75 |
| Heat Pump | COP 3.5 | Electricity | $0.12/kWh | $0.68 |
| Gas Furnace | 80% AFUE | Natural Gas | $1.00/therm | $0.75 |
| Gas Furnace | 90% AFUE | Natural Gas | $1.20/therm | $0.80 |
| Gas Furnace | 95% AFUE | Natural Gas | $1.50/therm | $0.95 |
Note: Lower cost depends on energy prices and system efficiency. Heat pumps perform better in mild climates.
FAQs About Heat Pump vs Gas Furnace Calculator
It is a tool that compares heating costs between a heat pump and a gas furnace using energy rates and efficiency values.
It depends on electricity and gas prices. Heat pumps are cheaper in mild climates, while gas furnaces work better in very cold areas.
You need home size, energy costs, system efficiency, and climate data.
The calculator gives reliable estimates if you enter accurate data. Real costs may vary based on usage and insulation.
Yes. Heat pumps can deliver 2–4 times more heat energy than the electricity they use.
Yes. You can use it for small apartments or large houses by adjusting the input values.
Yes. Heat pumps lose efficiency in very cold weather, while gas furnaces maintain stable performance.
Consider energy costs, climate, and installation cost before switching.
COP (Coefficient of Performance) measures heat output per unit of electricity used.
AFUE (Annual Fuel Utilization Efficiency) shows how efficiently the furnace converts fuel into heat.
