1. What is Propane Burn Rate?

The propane burn rate calculates how much propane an appliance consumes per hour based on its BTU rating and the energy content of propane. This helps estimate propane usage and tank duration.

2. How Does the Calculator Work?

The calculator uses the propane burn rate formula:

Where:

• Appliance BTU — The British Thermal Units per hour rating of your appliance
• Propane BTU per Gallon — Typically 91,000 BTU per gallon of propane

Explanation: The equation divides the appliance's energy consumption by propane's energy content to determine consumption rate.

3. Importance of Burn Rate Calculation

Details: Knowing your propane burn rate helps estimate how long your propane supply will last, plan refills, and compare appliance efficiency.

4. Using the Calculator

Tips: Enter the appliance's BTU rating (found on specification plate) and propane BTU value (default is 91,000). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's the typical BTU per gallon for propane?
A: Propane contains about 91,000 BTU per gallon, though this can vary slightly (91,500-92,000 BTU) depending on purity and temperature.

Q2: How can I find my appliance's BTU rating?
A: Check the manufacturer's label or specification plate on the appliance, or consult the owner's manual.

Q3: Why is my actual usage different from calculated?
A: Real-world factors like temperature, altitude, appliance efficiency, and usage patterns affect actual consumption.

Q4: How do I estimate my propane tank duration?
A: Divide your tank size (in gallons) by the burn rate to estimate hours of continuous operation.

Q5: Does this work for natural gas appliances?
A: No, natural gas has different energy content (about 1,030 BTU/cubic foot). A separate calculation is needed.
