Heat Pump Vs Gas Furnace Cost Calculator


Choosing the right heating system for your home is a significant decision that can impact your comfort and energy bills. Two common options are heat pumps and gas furnaces, each with its own advantages and costs. The Heat Pump Vs Gas Furnace Cost Calculator helps you compare the heating costs of these two systems based on the area you need to heat and energy prices.


To compare the heating costs, we use the following formulas:

  • Gas Heating Cost = (Area to Heat / 1000) * 100 * Gas Price per Therm
  • Electric Heating Cost = (Area to Heat / 1000) * 3.412 * Electricity Price per Kilowatt-hour

How to Use

Using the Heat Pump Vs Gas Furnace Cost Calculator is straightforward:

  1. Enter the total area you need to heat in square feet.
  2. Input the price of gas per therm in dollars.
  3. Specify the price of electricity per kilowatt-hour in dollars.
  4. Click the "Calculate" button.

The calculator will provide you with a cost-effective recommendation based on your input.


Let's say you need to heat an area of 2,000 square feet. The price of gas is $1.50 per therm, and electricity costs $0.12 per kilowatt-hour. The calculator would determine the heating costs as follows:

  • Gas Heating Cost = (2,000 sqft / 1000) * 100 * $1.50 = $300
  • Electric Heating Cost = (2,000 sqft / 1000) * 3.412 * $0.12 = $82.48

In this example, a gas furnace is more cost-effective.


1. What are the factors that affect the choice between a heat pump and a gas furnace?

  • Factors include energy prices, climate, installation costs, and personal preferences.

2. Does this calculator consider the heating system's efficiency?

  • No, it assumes both systems have the same efficiency. Actual efficiency may vary.

3. Is this calculator suitable for commercial heating cost comparisons?

  • Yes, it can be used for both residential and commercial applications.

4. Can I use this calculator for cooling cost comparisons in addition to heating?

  • The calculator is designed for heating cost comparisons only.

5. How often should I update the energy prices in the calculator?

  • It's a good idea to update prices periodically to reflect current rates.

6. Can I save my calculations for future reference?

  • This calculator does not have a save feature, so consider noting down your results.

7. Are taxes and maintenance costs included in the estimate?

  • No, taxes and maintenance costs are not included; you should account for them separately.

8. How can I factor in additional features like a programmable thermostat?

  • These features are not included in this calculator and should be budgeted separately.

9. Can I use this calculator for cost comparisons in different currencies?

  • Yes, you can use it with any currency, as long as all values are in the same currency.

10. Does the calculator provide a precise estimate for areas with extreme climate conditions? - The calculator provides a basic cost comparison; for extreme conditions, you may need a more detailed analysis.


The Heat Pump Vs Gas Furnace Cost Calculator is a valuable tool for homeowners and businesses looking to compare heating costs. By considering the area to heat and energy prices, you can make an informed decision about which heating system is more cost-effective for your needs. Whether you prioritize cost savings or environmental concerns, this calculator simplifies the process of comparing heat pump and gas furnace heating expenses.
