How much does it cost to run a gas fire pit per hour?
Take the pit's BTU rating and divide: by 100,000 for therms per hour on natural gas, or by about 91,500 for gallons per hour on propane — then multiply by the rate on your gas bill or your last tank price. A 60,000 BTU pit like Napoleon's Uptown burns about two-thirds of a gallon of propane per hour at full blast.
Full blast is the ceiling, not the habit
A rating like the Uptown's 60,000 BTU describes the maximum. In practice you light it tall for the first stretch, then settle into a half flame that burns roughly half the fuel — and on a typical WNC evening, where the temperature slides the minute the sun drops behind the ridge, a cruising flame is plenty. Your real per-hour cost lands well under the wide-open math. Elevation is the fire pit's best friend here: our evenings run cool most of the year, so the thing earns its keep from March through November instead of eight weekends a summer.
Natural gas changes the experience
If you're on the mains — much of Asheville, Hendersonville, Fletcher, and Arden — a buried natural-gas line to the patio means no tanks, no swaps, no flame going weak as a cylinder empties: metered fuel and fire at the turn of a key. Out in propane country — Fairview, Candler, Brevard, and the cabins — we run buried, outdoor-rated line from the house tank instead, which beats hauling 20-pounders in every way. Either way, in North Carolina an outdoor gas line is licensed work: we trench it, size it, permit it with your county, pressure-test it, and meet the inspector. That's the part of a fire pit project a hardscaper legally can't touch — and it's our lane.
Cost control starts at the design
Two decisions set your running cost for the life of the pit: burner size and fuel source. A right-sized burner with a good turndown gives you the tall party flame when you want it without forcing you to pay for it every quiet Tuesday night.
