A 20 lb propane tank holds roughly 430,000 BTU of fuel, which means a fire pit burning at 60,000 BTU runs approximately 7 hours on a full tank.

That 7-hour figure assumes the fire pit runs at full output the entire time — which most people don't do. Drop to a medium flame setting and you're realistically looking at 10–14 hours from the same tank. Panovue's 24-inch propane fire pit is rated at 60,000 BTU, so those numbers apply directly to that model. Higher-output patio heaters or fire tables with larger burners will burn through the same tank faster.

  • A standard 20 lb propane tank contains approximately 430,000 BTU of usable fuel.
  • Panovue's 24-inch propane fire pit outputs 60,000 BTU at full burn, yielding roughly 7 hours per tank.
  • Reduced flame settings (30,000–40,000 BTU range) extend a 20 lb tank to approximately 10–14 hours of burn time.
  • A 20 lb propane tank typically weighs about 37 lbs when full and 17 lbs when empty.
