1. What is This Calculator?

This calculator compares the operating costs between propane and electric dryers based on energy consumption rates and local utility prices.

2. How Does the Calculator Work?

The calculator uses these formulas:

Where:

\( BTU \) — British Thermal Units (energy content of propane)
\( Efficiency \) — Dryer efficiency (typically 0.7-0.8)
\( Hours \) — Usage time in hours
\( Propane Rate \) — Cost per gallon of propane
\( kW \) — Kilowatt rating of electric dryer
\( Elec Rate \) — Cost per kilowatt-hour of electricity

3. Importance of Cost Comparison

Details: Comparing operating costs helps determine the most economical choice based on local energy prices and usage patterns.

4. Using the Calculator

Tips: Enter all required values. Typical propane dryer uses 18,000-25,000 BTU/hour. Electric dryers typically use 5-7 kW.

5. Frequently Asked Questions (FAQ)

Q1: Which is generally cheaper to operate?
A: It depends on local energy prices. In areas with cheap electricity, electric may be cheaper. Where propane is inexpensive, it may have lower operating costs.

Q2: What's a typical efficiency for propane dryers?
A: Most propane dryers are 70-80% efficient (0.7-0.8 decimal value).

Q3: Does this include installation costs?
A: No, this only compares operating costs. Installation differs significantly between fuel types.

Q4: How do I find my local propane and electricity rates?
A: Check your utility bills or contact your local providers for current rates.

Q5: Are there other factors to consider?
A: Yes, consider venting requirements, maintenance, safety, and environmental impact when choosing between fuel types.
