1. What is a Propane vs Electric Heat Cost Calculator?

Definition: This calculator compares the cost of generating heat using propane versus electricity based on energy requirements and local fuel prices.

Purpose: It helps homeowners and businesses determine the most cost-effective heating method for their needs.

2. How Does the Calculator Work?

The calculator uses two formulas:

Where:

• \( \text{Cost}_p \) — Propane heating cost ($)
• \( \text{Cost}_e \) — Electric heating cost ($)
• \( \text{BTU} \) — Heat energy required (BTU)
• \( \text{Efficiency}_p \) — Propane system efficiency (0-1)
• \( \text{Price}_p \) — Propane price ($/gallon)
• \( \text{Efficiency}_e \) — Electric system efficiency (0-1)
• \( \text{Price}_e \) — Electricity price ($/kWh)

Explanation: The formulas convert BTU requirements to fuel units needed, then multiply by fuel prices to get total cost.

3. Importance of Heat Cost Comparison

Details: Choosing the right heating method can significantly impact operational costs, especially for large heating requirements.

4. Using the Calculator

Tips: Enter your heat requirement in BTU, system efficiencies (default 0.90 for propane, 1.00 for electric), and local fuel prices.

5. Frequently Asked Questions (FAQ)

Q1: What's the 91,000 factor for propane?
A: 1 gallon of propane contains approximately 91,000 BTU of energy.

Q2: What's the 3,412 factor for electricity?
A: 1 kWh of electricity contains 3,412 BTU of energy.

Q3: Why is electric efficiency often 1.00?
A: Electric resistance heating is nearly 100% efficient at point of use, though power generation isn't.

Q4: How do I find my heating requirement in BTU?
A: Use a heat loss calculator or consult HVAC professional for your specific space.

Q5: Which is usually cheaper?
A: This depends on local fuel prices - propane is often cheaper per BTU but electric may be more efficient.
