1. What is a Heating Cost Comparison Calculator?

Definition: This calculator estimates the cost of heating by comparing different fuel sources based on energy use, price per unit, and system efficiency.

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

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• Cost — Total heating cost in dollars
• Energy Use — Amount of energy consumed in units (therms, kWh, etc.)
• Price per Unit — Cost of one unit of energy in dollars
• Efficiency — System efficiency as a percentage (e.g., 80% = 0.8)

Explanation: The formula accounts for both the raw energy costs and how efficiently your system converts that energy into usable heat.

3. Importance of Heating Cost Comparison

Details: Comparing heating costs helps identify potential savings, evaluate system upgrades, and make informed decisions about energy sources.

4. Using the Calculator

Tips: Enter the energy use in units, price per unit in dollars, and system efficiency percentage. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: What energy units should I use?
A: Use consistent units (therms for gas, kWh for electricity, gallons for oil) when comparing different systems.

Q2: Where can I find my system's efficiency?
A: Check your equipment specifications or look for AFUE ratings (Annual Fuel Utilization Efficiency).

Q3: Should I include delivery charges in price per unit?
A: Yes, include all costs associated with obtaining the fuel (base rate + delivery + taxes).

Q4: How does efficiency affect costs?
A: Higher efficiency systems require less fuel to produce the same amount of heat, lowering costs.

Q5: Can I compare different fuel types?
A: Yes, but you'll need to convert all energy use to equivalent heat output (BTUs) first.
