What is a Propane Generator Tool?
The Propane Generator Tool calculates fuel consumption, runtime, and efficiency for propane-powered generators. It helps users plan for emergency power needs, optimize fuel usage, and estimate generator performance for residential or commercial applications.

Formula
Runtime (hours) = (Tank Size (lbs) × 21,548 BTU/lb × Efficiency) / (Wattage × 3.412 BTU/watt)
This formula calculates generator runtime by converting propane mass to energy content, applying efficiency, and dividing by power demand.
Advantages and Disadvantages
Advantages
- Clean Energy: Propane burns cleaner than diesel or gasoline, producing fewer emissions.
- Long Shelf Life: Propane can be stored indefinitely without degradation, making it ideal for emergency backup power.
- Cost-Effective: Propane generators are often more affordable to operate than diesel generators, especially in areas with low propane prices.
- Quiet Operation: Propane generators typically operate more quietly than diesel generators.
- Portability: Propane tanks are easy to transport and refill, making them suitable for remote locations.
Disadvantages
- Lower Energy Density: Propane contains less energy per gallon compared to diesel, resulting in shorter runtimes.
- Storage Requirements: Large propane tanks require significant space and proper safety measures.
- Fuel Availability: Propane may not be readily available in all areas, especially during emergencies.
- Cold Weather Performance: Propane generators may struggle in extremely cold temperatures due to fuel vaporization issues.
- Initial Cost: Propane generators can have higher upfront costs compared to gasoline models.
FAQs
How much propane does a generator use?
Propane consumption depends on generator wattage and load. A 5,000-watt generator typically uses 1-2 pounds of propane per hour at 50% load. Use the calculator above for precise estimates based on your generator's specifications and usage patterns.
How long will a generator run on propane?
Runtime varies by tank size and generator efficiency. A 20-pound propane tank can power a 5,000-watt generator for 10-15 hours at half load. Larger tanks or lower loads extend runtime significantly.
How much propane does a Generac generator use?
Generac propane usage depends on the model. A 22kW Generac generator uses approximately 2-3 gallons per hour at full load. Always refer to the manufacturer's specifications for accurate consumption rates.
Can you use flex line for propane generator?
Yes, flexible gas lines can be used for propane generators if they are rated for propane and installed by a licensed professional. Ensure proper sizing and pressure ratings for safe operation.
How long can a generator run on propane?
Propane generators can run continuously as long as fuel is available. However, maintenance intervals and cooling periods are recommended for prolonged use. Always monitor fuel levels and generator temperature during extended operation.
