A permanent outdoor kitchen and a movable backyard grill can demand very different fuel setups. Choosing between a natural gas vs propane grill affects where the appliance can be placed, how it receives fuel, what it costs to operate, and how easily it can be moved later. The best option depends less on cooking power and more on how frequently you grill, the infrastructure available at your home, and the flexibility you want from your patio layout.
A clear comparison can keep fuel logistics from complicating your outdoor cooking plans. Gerhard’s Appliances offers premium grills and expert guidance to help homeowners select a model suited to their space and cooking habits. This guide compares natural gas and propane by supply method, installation cost, long-term expense, portability, and heat performance so you can choose your next grill with confidence.

Explore GrillsKey Takeaways
- Fuel Supply Differences: Natural gas connects directly to your home utility line for endless fuel, while liquid propane relies on portable 20-pound tanks.
- Identical Cooking Power: Propane contains more energy per cubic foot, but manufacturers size burner orifices larger on natural gas models to produce equal heat output.
- Operating Costs: Natural gas costs significantly less per cooking hour, though installing a dedicated gas line adds upfront expense.
- Portability: Propane grills move freely around your yard or deck, whereas natural gas grills remain fixed to their utility connection point.
How Natural Gas and Liquid Propane Power Your Grill
The primary difference between these two outdoor cooking options lies in how fuel reaches your burners. Liquid propane grills store fuel under pressure inside portable steel cylinders, most commonly standard 20-pound tanks. You can move these tanks easily, but you must monitor fuel levels and visit a store periodically for refills or exchanges.
Natural gas grills feed directly from your municipal utility grid through a permanent pipe connected to your house. This setup provides a continuous supply of fuel, meaning you never run out mid-cook or deal with heavy tanks. However, using natural gas requires having an existing utility connection or completing a natural gas line installation for grill use on your patio.
The fuel connection also affects how you plan the surrounding outdoor space. A natural gas grill must remain within reach of its approved connection, making it best suited to a permanent patio or built-in outdoor kitchen. Propane offers greater freedom for homeowners who rearrange furniture, store the grill during winter, or move it between cooking areas. Frequent grillers may appreciate the uninterrupted supply of natural gas, while occasional cooks may prefer the lower upfront commitment of a propane model. Consider both your current layout and future renovation plans before selecting a fuel type.
Heat Output and Cooking Performance Differences
A common myth in backyard cooking is that propane grills cook hotter than gas line models. On paper, propane holds more raw energy by volume.
However, do propane grills burn hotter in actual practice? Grill manufacturers engineer each model to offset this energy density difference. Natural gas models utilize larger burner orifices and adjusted valves to feed more fuel volume into the combustion chamber. When evaluating a natural gas vs propane grill, both fuel options yield identical searing capability, maximum temperatures, and flame control.
Fuel type is only one factor in cooking performance. Burner design, grate material, lid insulation, firebox construction, and wind protection can have a greater effect on preheating, heat retention, and temperature recovery. A well-built propane grill can outperform a lower-quality natural gas model, and the reverse is also true.
Natural Gas vs Propane: Side-by-Side Comparison
Comparing fuel types helps clarify which setup matches your cooking habits and patio layout.
| Fuel Type | Supply Method | Upfront Installation Cost | Long-Term Fuel Cost | Portability | Ideal Use Case |
|---|---|---|---|---|---|
| Natural Gas Grills | Permanent utility pipe line | Higher due to gas line installation | Lower operating cost per hour | Stationary patio placement | Frequent grillers wanting endless fuel supply |
| Liquid Propane Grills | Portable 20-pound tank | Minimal initial setup cost | Higher recurring tank refill costs | Fully mobile across yard or deck | Flexible patio layouts and portable gas grills |
For frequent entertainers with an established outdoor kitchen, natural gas often provides the strongest long-term convenience because it removes tank monitoring and mid-cook fuel changes. Propane is often the better match for renters, smaller patios, and homeowners who value mobility or want to avoid permanent utility work. The propane vs natural gas grill cost comparison should include installation, expected cooking frequency, local fuel rates, and future patio plans. Looking at the complete ownership experience makes it easier to choose a grill that fits both your budget and routine.
Can You Switch Between Natural Gas and Propane?
Connecting a propane grill directly to a natural gas line without proper modification creates an extreme fire hazard. Propane operates under higher pressure through smaller orifices. Running natural gas through tiny propane fittings creates a weak, unusable flame, while pushing high-pressure propane through larger natural gas fittings causes dangerous flare-ups.
How Conversion Kits Function
To change fuel sources safely, you must install an official natural gas grill conversion kit approved by the manufacturer. These kits include:
- New burner orifices sized specifically for lower-pressure natural gas.
- A compatible gas pressure regulator.
- A flexible hose with a quick-disconnect fitting.
Keep in mind that not all grill lines permit fuel switching. Altering fuel components without manufacturer support can void your product warranty and breach local safety codes.

Natural Gas vs Propane Grill FAQs
Yes, natural gas costs significantly less per unit of energy than liquid propane tank refills. Homeowners who cook frequently save money over time despite the initial line installation cost.
No, natural gas grills deliver identical cooking temperatures, heat distribution, and searing capabilities as propane models. Manufacturers equip natural gas units with larger fuel orifices to compensate for lower fuel density.
Yes, you can convert many propane models using a manufacturer-approved natural gas conversion kit. You must replace the burner orifices, gas hose, and regulator to guarantee safe operation under lower pressure.
Propane contains more energy per cubic foot than natural gas, but grills do not actually cook hotter. Manufacturers balance heat output by sizing natural gas orifices larger to deliver equal BTU performance at the grate.
Connecting an appliance to your home utility line requires working with high-pressure gas pipes and local building codes. Hiring a licensed professional prevents dangerous gas leaks and verifies proper shutoff valve placement.
Propane gas grills are safe on open outdoor balconies if permitted by local fire codes and building regulations. You must maintain proper clearance from combustible walls and never store extra propane cylinders indoors.
