Key takeaways
- Natural gas is cheaper to run but needs a line.
- Propane gives taller flames and works anywhere.
- Tank location is the main propane design decision.
- Both burn clean, with no smoke or ash.
Same idea, different supply
Both fuels run through a burner under glass or stone. The difference is how the gas arrives: a buried pipe from your meter, or a tank you fill or swap.
Running cost
Natural gas is generally cheaper per hour of burn than propane, which matters if you burn often. Propane costs more per hour but costs less to set up when no line is nearby.
Flame and heat
Propane contains more energy per cubic foot, so flames tend to burn taller and a little yellower. Natural gas flames are slightly softer and bluer at the base. Burner design matters just as much.
Setup and placement
Natural gas needs a line run, permit and inspection. Propane needs a tank spot and a refill plan, which can be hidden in a table base or buried. Propane lets you place the fire anywhere.
Which should you pick?
If you have gas at the house and burn often, natural gas is usually the better long-term choice. If you are far from gas, or want flexibility, propane is excellent.

Quick answers
Can I convert a natural gas pit to propane?
Often yes with the right orifice and regulator, but it must be done properly by a qualified installer. Never swap fuels on your own.
How often do I refill a propane tank?
It depends on tank size and how often you burn. A 20 lb tank gives roughly 8 to 10 hours of burn at full flame.
