The grilling time of a propane tank depends on the tank size, grill BTU output, and heat settings. A standard 20-pound propane tank lasts 18-20 hours on a medium grill, but high heat settings will shorten this time.
Grilling Hours by Propane Tank Size
💡 Tip: Cooking on high heat reduces propane life faster than grilling on low or medium heat.
Grilling Hours by Grill BTU Output
📌 Note: A 20-lb propane tank provides approximately 430,000 BTUs of energy.
How to Check Propane Levels
✔ Weigh the Tank – A full 20-lb tank weighs about 37 lbs. Subtract the tare weight (empty weight) to estimate remaining propane.
✔ Use the Warm Water Test – Pour warm water down the side of the tank. The propane level is where the metal feels cool.
✔ Install a Propane Gauge – Attach a tank gauge for an exact reading.
Tips to Extend Propane Life
✅ Use Low to Medium Heat – Reduces gas consumption.
✅ Keep the Lid Closed – Traps heat and improves efficiency.
✅ Clean Your Grill – Dirty burners can waste propane.
✅ Check for Leaks – A leaking tank wastes fuel.
FAQs
1. How long does a 20-lb propane tank last for grilling?
A 20-lb tank lasts 18-20 hours on a medium-sized grill at moderate heat.
2. How do I know when my propane tank is empty?
Check the tank weight, use the warm water test, or install a propane gauge.
3. Can I refill a propane tank instead of replacing it?
Yes! Refilling is usually cheaper than exchanging a tank.
4. Do different grills use propane at different rates?
Yes, higher BTU grills consume propane faster than lower BTU models.
5. Can I store propane tanks outside?
Yes, but keep them in a shaded, well-ventilated area, away from extreme heat.
Final Thoughts
A 20-lb propane tank lasts 8 to 20 hours, depending on grill BTU output and heat settings. To maximize usage, grill on medium heat, keep the lid closed, and monitor propane levels regularly. 🔥🥩
