1. What is a Heat Pump vs Gas Cost Calculator?

Definition: This calculator compares the annual operating costs of a heat pump versus a traditional gas heating system.

Purpose: Helps homeowners and businesses evaluate the potential cost savings of switching to a heat pump system.

2. How Does the Calculator Work?

The calculator uses these formulas:

\[ \text{Heat Pump Cost} = \frac{\text{Energy Needed}}{\text{COP}} \times \text{Electricity Rate} \] \[ \text{Gas Cost} = \text{Energy Needed} \times \text{Gas Rate} \]

Where:

Energy Needed — Annual heating requirement in kWh
COP — Coefficient of Performance of heat pump (typically 2.5-4.0)
Electricity Rate — Cost per kWh of electricity
Gas Rate — Cost per kWh equivalent of natural gas

3. Importance of Cost Comparison

Details: Understanding the cost difference helps in making informed decisions about heating system upgrades and evaluating payback periods.

4. Using the Calculator

Tips: Enter your annual heating needs, heat pump efficiency (COP), and local utility rates for accurate comparisons.

5. Frequently Asked Questions (FAQ)

Q1: What is COP in heat pumps?
A: Coefficient of Performance measures efficiency - higher COP means more heat output per unit of electricity.

Q2: How do I find my annual energy needs?
A: Check your utility bills or use our Energy Needs Calculator tool.

Q3: Does this include installation costs?
A: No, this only compares operating costs. Consider installation costs separately.

Q4: Why compare per kWh?
A: Comparing per energy unit (kWh) provides an equal basis for different fuel types.

Q5: How accurate are these estimates?
A: They're approximations. Actual costs vary with system efficiency, climate, and usage patterns.
