Natural Gas vs Propane Grills — Which Fuel Is Right?
Natural gas and propane grills cook in much the same way. The real differences are fuel cost, how the grill is installed, and whether you can move it. This comparison covers those trade-offs so you can match the fuel to your yard and habits.
| Attribute | Natural Gas | Propane |
|---|---|---|
| Running Cost | Generally cheaper per cook over time | Generally costs more per cook; tanks must be refilled or swapped |
| Convenience | No refills, so the fuel never runs out mid-cook | Easy to run out unless you keep a spare tank |
| Portability | Fixed to a gas line | Moves anywhere you can carry a tank |
| Installation | Needs a gas line, typically installed by a licensed pro | Connect a tank and cook |
| Best For | Permanent outdoor kitchens and patios with a gas line | Renters, movers, and anyone without a line |
| Verdict | Best long-term value if you have a line | Best flexibility and lowest setup effort |
Running Cost
Natural gas is usually the cheaper fuel for the energy it delivers, and the gap widens the more you grill. Propane costs more per cook, and you pay in tank refills or exchanges. Exact rates vary by region and utility, so check local prices before assuming a payback period.
If you grill a few times a month, the difference is modest. If you grill several times a week, natural gas savings add up.
Convenience and Portability
Natural gas wins on convenience because there are no tanks to track. Propane wins on portability. You can place a propane grill anywhere, rotate it around the yard, or take it with you when you move.
Brands such as Weber (from $529) and Napoleon (from $549) sit at accessible price points for people who want a propane-ready freestanding grill. At the lowest end, Magma Grills starts at $508, the cheapest price on the site. Check each product page for the fuel type before you buy.
Installation Needs
Propane needs almost no installation beyond assembling the grill and connecting a tank. Natural gas needs a gas line to the cooking spot. Running or extending that line is usually a job for a licensed professional, and local codes may require permits.
That extra cost matters most for built-in grills, which sit in a fixed outdoor kitchen where a gas line is usually planned from the start. Brands like Blaze ($1,394 to $18,500) and Fire Magic ($985 to $18,500) cover a wide range of budgets for those projects. For flexibility, freestanding grills are the easier fit. Broil King ($599 to $8,799) is one option in that space.
Conversion Kits
Many grills can be switched between fuels with a conversion kit, but not all of them. Some models are built for one fuel only. A conversion typically involves swapping parts that control gas flow, and the correct kit depends on the specific grill.
Before buying, confirm in the product listing or manual whether your model is convertible. Have a qualified technician do the work and leak-test the connections afterward. If you might move to a home with a gas line later, a convertible model gives you room to change.
Who Should Choose Each
Choose natural gas if:
- You have a gas line near the patio, or you are planning an outdoor kitchen.
- You grill often and want the lowest running cost.
- You want a permanent setup with no tanks.
Choose propane if:
- You do not have a gas line and do not want to install one.
- You rent, expect to move, or want to reposition the grill.
- You grill occasionally and value simple setup.
If budget is the main constraint, our guides to entry-level gas grills starting around $500, gas grills under $1,000, and gas grills under $2,000 show what each tier offers. You can also browse all brand reviews to compare makers.
Verdict
Choose natural gas if you already have a line or are building a permanent outdoor kitchen. It costs less to run and never needs a refill. Choose propane if you want easy setup and the freedom to move the grill. For most renters and first-time buyers, propane is the practical pick. For long-term homeowners with a line, natural gas is the better value.
Common Questions
Can I convert my propane grill to natural gas?
Often yes, but only if the manufacturer offers a conversion kit for your specific model. Check the manual or product listing first, and have a qualified technician install it and test for leaks.
Is natural gas hotter than propane?
Not in a way that matters for most home cooks. Properly set up, both fuels can sear and cook well, and results depend more on burner design and grill construction than on the fuel itself.
Is a natural gas grill cheaper to buy?
The grill itself is often priced similarly regardless of fuel. The extra cost for natural gas usually comes from running a gas line, while propane adds the cost of tanks and refills. Compare the full cost, including installation, before deciding.
