If you enjoy outdoor cooking and are shopping for a new grill, you may notice that natural gas models often cost more than propane models. The price gap can be surprising when two grills look almost the same.
Natural gas grills often cost more because they require fuel-specific parts, such as a natural gas hose, fittings, and regulator, and are frequently sold in higher-end or built-in lineups. You may also need to pay a professional to install a gas line to your patio. Some brands also use sturdier materials and additional safety features in models designed to connect to a home gas supply.
The sticker price is not the full story. Lower natural gas prices allow many owners to spend less on fuel over time. Because natural gas costs less per unit of heat, you save money while avoiding propane tank refills. Read on to see where the money goes and whether a natural gas grill makes sense for your home.
What Drives the Upfront Price Gap?
A natural gas grill often costs more than a comparable propane grill. The gap reflects the parts needed to connect to a home gas line and the higher-end product lines where many natural gas models are sold.
Comparing Equivalent Natural Gas and Propane Models
Many brands sell the same grill in two versions, one for each fuel. When you compare equivalent models, natural gas grills may cost $200 to $500 more upfront than propane grills, depending on the brand and model.
The cooking area, burner count, and body may be the same. The main differences are in the fuel connection and components designed for each gas type.
| Feature | Propane Grill | Natural Gas Grill |
|---|---|---|
| Fuel supply | Portable tank | Fixed home gas line |
| Burner orifices | Smaller openings | Larger openings |
| Connection | Tank regulator and short hose | Gas line hose and fittings |
| Sales volume | Higher | Lower |
Propane grills generally sell in larger numbers. If natural gas models are produced in smaller batches, the lower production volume may contribute to a higher cost per unit.
Fuel-Specific Parts and Premium Product Lines
Natural gas and propane operate at different pressures, so grills designed for each fuel use different components.
Common natural gas grill components include:
- Larger burner orifices that allow more gas to flow for a similar heat output
- A regulator or valve setup matched to the grill and gas supply
- A hose that connects the grill to an outdoor natural gas line
Natural gas models also require fuel-specific engineering and safety features suited to their intended gas supply and pressure.
Many low-cost grills are available only in propane versions. Natural gas models are more common in mid-range and high-end product lines, which may use stainless steel and heavier components. This can raise the average price of the natural gas grills available to shoppers.
Gas Line Installation and Safety Costs
Installing a gas line can be a major additional cost for a natural gas grill, especially if your yard does not already have an outdoor hookup. Labor, permits, and safety checks may also add to the total.
Existing Outdoor Hookups Versus New Line Runs
If you already have an outdoor gas stub with a shutoff valve, connecting the grill may be straightforward. A qualified professional can connect the grill and check the setup for leaks.
Installing a new natural gas line typically costs more. The price depends on the pipe required and the route it must take, including whether it needs to run under a patio or across a long distance in your yard.
| Item | Typical Cost |
|---|---|
| Gas pipe | $15–$25 per linear foot |
| Gas shutoff valve | $35–$75 each |
| Pressure gauge | $10–$100 each |
| New gas line (average) | About $550 extra |
These estimates are based on gas grill installation cost data, which puts many total projects between $200 and $1,200. Actual costs vary by location and project requirements.
Before you buy, check whether natural gas service is available at your home. If your property does not have gas service, the utility may need to extend a line to the house, adding cost and time.
Professional Labor, Permits, and Safety Checks
A licensed natural gas plumber may charge $50 to $150 per hour. A straightforward grill hookup may take 1 to 3 hours, while more complex installations can take longer.
Many cities require a permit for gas line installation. Permit fees vary by location, so review local permit fees and labor and material costs when planning your budget. Safety work is part of the installation.
A qualified professional may:
- Seal pipe joints with approved sealant
- Pressure test the line for leaks
- Install a shutoff valve near the grill
- Check that the installation meets local code
Doing the work yourself may save on labor, but gas leaks can cause fires. Check local rules and the grill manufacturer’s instructions, and consider hiring a licensed professional for gas line work.
Construction Quality and Durability
Heavier metals, sturdier carts, and longer warranties on parts such as burners and cookboxes can add to a grill’s price. Some upgrades may improve durability, but price alone does not prove that a grill is better built.
How Materials and Build Quality Affect Price
Some manufacturers use stainless steel, cast iron, and high-grade aluminum to resist corrosion and support long-term use. These materials generally cost more than painted steel. Thicker panels and stronger hinges can also raise the price.
Weight can offer one clue about construction, but it is not a complete measure of quality. In one comparison, a $349 Char-Broil weighed 79 pounds, while a $999 Weber weighed 135 pounds. The 56-pound difference suggests the Weber has a heavier overall build, but it does not show the thickness or quality of every component.
You can check a grill’s construction in a store:
- Open and close the lid several times.
- Push gently on each side shelf.
- Roll the grill a few feet to check for wobbling.
- Make sure the doors and grease tray line up.
Which Components Are Worth Paying More For
Not every component on a natural gas grill needs to be upgraded. Focus on the parts exposed to the most heat and wear.
| Component | What to Look For |
|---|---|
| Burners | Stainless steel or cast iron burners with substantial warranty coverage |
| Cookbox and lid | Heavy castings or thick panels |
| Grates | Porcelain-coated cast iron or thick stainless steel rods |
| Cart | Stable frame with secure fasteners |
Cast iron burners retain heat well, but they can rust if they are not kept clean and dry.
Check the warranty for each component. A longer component warranty may be more useful than a large headline warranty claim. For example, the Weber covers its cookbox and lid for 12 years, while the Char-Broil covers its lid and firebox for 2 years. Warranty terms vary by model, so check the manufacturer’s current coverage.
Premium Features That Raise the Sticker Price
Advanced grill features, specialty burners, and accessories such as rotisserie kits can add hundreds of dollars to a natural gas grill. These high-end grill features require additional parts and labor, and some also need dedicated gas lines.
Extra Burners and Flexible Cooking Zones
A basic grill may have two or three main burners, while higher-priced models often have four to six. More burners let you create multiple cooking zones, so you can sear steaks over high heat on one side and cook vegetables over lower heat on the other.
Many grills also include specialty burners:
| Burner Type | What It Does |
|---|---|
| Side burners | Heat pots and pans for sauces or side dishes |
| Infrared burners | Reach high temperatures for fast searing |
| Rotisserie burners | Sit at the back and cook meat slowly as it turns |
Each additional burner typically needs its own valve and control knob, and may require a dedicated gas line. High-output side burners require separate plumbing connections, while infrared burners use specialized ceramic plates.
Brands that focus on infrared technology and heat distribution often charge a premium for these high-performance infrared burners.
Ignition Systems and Optional Accessories
The ignition setup also affects the price. Lower-cost grills often use a push-button spark igniter, while pricier models feature electronic ignition systems that light each burner independently.
Multi-spark electronic ignition systems require extra wiring and battery compartments. Some higher-end grills also include backlit or LED control knobs for cooking after dark. Accessories can add to the cost.
Common options include:
- Rotisserie kits with a motor, spit rod, and forks
- Smoker boxes that hold wood chips for smoky flavor
- Grill lights and covers
High-end units often feature built-in smoker boxes with dedicated burner controls. While standalone smoker boxes are inexpensive, integrated systems require extra engineering and materials.
Some grills include these items, while others sell them separately. Before buying, check which extras come with the grill so you can compare each model’s total cost.
Fuel and Lifetime Ownership Costs
Natural gas may cost less than propane for the same amount of heat, which can lower your fuel bill. Whether those savings offset the higher purchase price and installation cost depends on how often you grill, local fuel prices, and your gas-line setup.
Comparing Natural Gas and Propane Costs per Unit of Heat
To compare fuel costs fairly, compare the price per unit of heat rather than the price per tank or bill. Natural gas is often billed in therms, with one therm equal to 100,000 BTUs. One gallon of propane contains about 91,500 BTUs.
One cited price range puts natural gas at $1.00 to $1.50 per therm and propane at $2.50 to $3.50 per gallon equivalent. Actual prices vary by location and over time, so compare your local rates to estimate the difference.
| Fuel | Typical Price | Estimated Yearly Cost (Frequent Grilling) |
|---|---|---|
| Natural gas | $1.00–$1.50 per therm | $50–$75 |
| Propane | $2.50–$3.50 per gallon equivalent | $100–$150 |
These are estimates, not guaranteed costs. Natural gas prices vary by state and season, and propane prices also fluctuate. Check your utility bill and local propane prices to estimate your actual fuel costs.
Estimating Whether Fuel Savings Offset the Upfront Cost
Natural gas grills may cost more to buy. One cited comparison puts mid-range models at about $350 to $1,200 for natural gas, compared with $300 to $900 for propane. A gas-line installation can add to the upfront cost.
To estimate your payback time, follow these steps:
- Add your extra upfront cost. Include the price difference between the grills and any gas-line installation quote.
- Estimate your yearly fuel savings. The table above suggests savings of about $25 to $100 per year, though actual savings depend on local prices and how often you grill.
- Divide the extra cost by the yearly savings.
For example: if you pay $300 more in total and save $75 a year, you break even in about 4 years. If you grill only once a month, your savings may be smaller, extending the payback period.
Maintenance and Replacement Expenses
Some parts wear out on both grill types. Igniters, burners, hoses, and regulators may need replacing over time, and costs depend on the grill and the parts required.
Propane grills also involve tank-related tasks. Some guides note that propane grills may require additional tank maintenance.
- Tank requalification: In the U.S., propane tanks generally require requalification 12 years after manufacture, then every 5 years, subject to applicable regulations and the tank’s markings.
- Spare tanks: Some people keep a second tank on hand to avoid running out mid-cook.
- Safe storage: Propane tanks must be stored outdoors and upright.
With natural gas, you avoid propane tank costs. However, the quick-disconnect hose may need repair or replacement if it cracks or leaks.
When Is the Investment Worth It?
A natural gas grill may be worth the investment if outdoor cooking is a regular routine and you already have a natural gas line near your patio. It can also suit you if you are comfortable keeping the grill in one place and choose only the features you will use.
Choosing Based on Grilling Frequency and Gas Access
How often you grill is a key factor. A higher price may make more sense if you grill more than once a week. A well-built grill may last 12 to 15 years, while some budget grills may last only 3 to 5 years; lifespan varies with materials, use, and maintenance.
If you grill fewer than 10 times a year, a less expensive model may be enough.
Next, check natural gas availability. Your home needs a gas line, and extending one to your patio adds cost. You can compare installation costs and long-term value before buying.
| Your Situation | Is a Natural Gas Grill Worth It? |
|---|---|
| You grill weekly and have a gas line nearby | Likely yes |
| You grill weekly but have no gas line | Maybe, after you price the gas line |
| You grill a few times a year | Likely no |
Weighing Convenience Against Portability
The main convenience of a natural gas grill is its connection to a continuous fuel supply, so you do not need to swap or refill propane tanks. This is one of the main advantages of natural gas grills.
The trade-off is that the grill must stay connected to a gas line. You cannot take it camping, to a tailgate, or to a friend’s house.
Cooking results can be similar with either fuel when the grill is designed and set up for that fuel. Natural gas and propane grills can deliver comparable cooking performance. The choice is generally about fuel access, convenience, and cost rather than a guaranteed difference in flavor.
If you move often or rent your home, a portable propane grill may suit you better.
Avoiding Features You Will Not Use
Extra gas grill features can quickly raise the price. Before paying for them, consider your personal outdoor cooking habits and which grill features you will actually use.
Popular additions like built-in side burners or dedicated infrared burners add great flexibility, but they drive up costs if left unused.
Common add-ons include:
- Side burners for sauces or side dishes
- Rotisserie kits for whole chickens or roasts
- Infrared sear burners for steaks
- Extra main burners for large groups
If you rarely smoke food or prefer quick weeknight dinners, premium add-ons like integrated smoker boxes may simply add unnecessary expense.
Grill size matters, too. Running every burner on a large grill for a small meal can waste fuel and increase operating costs. If you usually cook for two to four people, a smaller grill with three or four burners is often enough.
Prioritize build quality, including durable materials and well-made burners. These components can have a greater effect on a grill’s longevity than extra features.

FAQ:Why Are Natural Gas Grills So Expensive?
Natural gas grills can be expensive because they often require durable burners, corrosion-resistant materials, and gas components designed for a permanent fuel connection. Some models also include premium cooking grates, advanced ignition systems, and larger cooking areas.
However, natural gas grills are not always more expensive than propane grills; the price largely depends on the brand, construction quality, and features.
Natural Gas Grills Require Specialized Gas Components
Natural gas grills are designed to operate on a specific fuel supply pressure and must use compatible burners, valves, regulators, and fittings. These components need to deliver gas safely and consistently to the burners.
A natural gas grill should not be connected to a propane supply unless the manufacturer explicitly supports the conversion and the correct conversion procedure is followed.
Many Natural Gas Grills Are Built for Permanent Installation
Some natural gas grills are designed for built-in outdoor kitchens or permanent patio installations. These models may feature heavier construction, stainless steel cabinets, larger cooking surfaces, and more elaborate installation requirements, all of which can increase the total cost.
However, portable and freestanding natural gas grills are also available, so permanent installation is not a requirement for every model.
Stainless Steel Construction Can Increase the Price
Many premium natural gas grills use stainless steel burners, cooking grates, fireboxes, and exterior panels. Higher-quality stainless steel can improve corrosion resistance and durability, particularly when the grill is exposed to rain or coastal air.
The grade, thickness, and quality of the steel matter more than the simple presence of a stainless steel finish. A grill with thicker, well-made components may cost more but can offer better long-term value.
Natural Gas Grills Can Cost More to Install
Unlike a propane grill that uses a portable cylinder, a natural gas grill needs a suitable gas connection. If your patio does not already have a gas line, installation may require professional work, approved piping, fittings, and local permits where applicable.
These installation costs are separate from the purchase price of the grill and can make the overall project considerably more expensive.
Are Natural Gas Grills Cheaper to Run?
Natural gas can be economical for frequent grilling, depending on local gas prices and the efficiency of the grill. Because it is supplied through a permanent connection, you also avoid buying or exchanging portable propane cylinders.
However, natural gas is not always cheaper than propane. The running cost depends on local fuel prices, consumption, and how often you grill. Installation expenses should also be considered when comparing the total cost of ownership.
Is a Natural Gas Grill Worth the Extra Cost?
A natural gas grill can be a good investment if you have an existing gas connection and grill frequently. You get a continuous fuel supply without needing to refill or replace a cylinder, which can be particularly convenient for regular outdoor cooking.
A propane grill may be the more economical choice if you grill occasionally, want portability, or would need to install a new gas line. Compare the grill’s construction, warranty, fuel costs, and installation requirements before deciding.
