Understanding Gas Fire Pit Fuel Types
Before diving into the details, let’s clarify the basics:
Propane Fire Pit: A propane fire pit uses liquid propane (LP) as its fuel source, stored in a refillable tank (usually 20 pounds, like those used for BBQ grills). Propane fire pits are popular for their convenience, portability, and easy setup. Explore our full range of fire pits to see all the available options for both propane and natural gas.
Natural Gas Fire Pit: A natural gas fire pit connects directly to your home’s natural gas supply via a dedicated gas line. This provides a continuous fuel source, eliminating the need for refills. Natural gas fire pits are often chosen for permanent or built-in outdoor setups.

Installation: Natural Gas Fire Pit vs Propane Fire Pit
Propane Fire Pit Installation
Propane fire pits are the easiest to set up. Simply connect the tank, check for leaks, and you’re ready to enjoy the flames. No trenching, permits, or professional installation required. This makes propane a favorite for renters, seasonal patios, or anyone who likes to rearrange their outdoor space.

Natural Gas Fire Pit Installation
Installing a natural gas fire pit is a more involved process. It requires a certified professional to run a gas line from your home to the fire pit location. This may involve trenching, permits, and a higher upfront cost. However, once installed, you’ll never need to worry about running out of fuel.

Key Considerations:
- Fire pit fuel line setup must comply with local codes.
- Natural gas fire pits are best for permanent backyard installations.
- Propane is ideal for flexible layouts or where gas lines aren’t available.
Performance and Heat Output
Which Fire Pit Burns Hotter: Propane or Natural Gas?
Propane generally delivers a higher BTU output per cubic foot than natural gas, meaning it can produce a hotter, more intense flame. This makes propane fire pits a great choice if you want maximum warmth or a dramatic flame effect.
- Propane: Around 2,500 BTUs per cubic foot
- Natural Gas: Around 1,000 BTUs per cubic foot

Flame Quality:
- Propane flames tend to be taller and more vibrant.
- Natural gas flames are softer and may be less visible in daylight.
Both fuels are efficient and clean-burning, but propane’s higher BTU output means you’ll use less volume for the same heat—though propane itself is typically more expensive than natural gas.
Cost and Value Factors: Budget, Convenience, and Long-Term Impact
When choosing between a natural gas and propane fire pit, it’s essential to look beyond the flames and consider the complete picture: initial investment, ongoing costs, maintenance, durability, and the potential impact on your home’s value and lifestyle. Here’s how each option stacks up:
Initial Cost
Propane Fire Pit: Propane fire pits are usually more budget-friendly upfront. Most models are designed for quick, do-it-yourself setup—just connect a standard propane tank and you’re ready to go. There’s no need for professional installation or permits, making propane an appealing choice for anyone seeking a cost-effective, convenient solution.
Natural Gas Fire Pit: Natural gas fire pits typically require a higher initial investment. Installation involves hiring a licensed professional, trenching, and possibly obtaining permits to lay a dedicated gas line. While the fire pit itself may be similar in price to propane models, these installation requirements can significantly increase your starting cost.
Ongoing Fuel Consumption and Cost-Effectiveness
Propane: Propane is generally more expensive per unit of energy than natural gas. If you use your fire pit frequently, you’ll need to budget for regular tank refills or replacements. However, propane fire pits allow you to control fuel consumption by adjusting the flame size, which can help manage ongoing costs. For occasional use or those who value flexibility, propane remains a convenient and manageable option.
Natural Gas: Natural gas is known for its cost-effectiveness, especially for regular or high-volume use. Once connected, you benefit from a continuous, uninterrupted fuel supply at a lower cost per hour than propane. There’s no need to worry about running out of gas or making extra trips for refills, which adds convenience and predictability to your outdoor enjoyment.
Maintenance Requirements and Durability
Propane Fire Pit: Maintenance for propane fire pits is straightforward—regularly check hoses and connections for leaks, and replace the tank as needed. The portable nature of propane fire pits means they might experience more wear and tear, but most are designed to withstand outdoor conditions. Keeping the unit covered when not in use helps extend its lifespan.
Natural Gas Fire Pit: Natural gas fire pits are low-maintenance after installation. Occasional inspection of the burner and gas line is recommended to ensure safe operation. Because these units are permanent fixtures, they tend to be more durable and less susceptible to accidental bumps or weather-related movement.

Long-Term Value and Home Impact
Home Value: Investing in a natural gas fire pit can boost your property’s appeal and value—especially when professionally installed as part of a well-designed outdoor living area. Many homebuyers see built-in fire features as a desirable upgrade, which can set your property apart from others on the market.
Lifestyle and Level of Convenience: Propane fire pits offer maximum flexibility. They’re ideal for renters, seasonal users, or anyone who enjoys rearranging their patio or deck. The ease of setup and ability to move the fire pit as needed make propane a popular choice for those with evolving outdoor spaces.
Natural gas fire pits, by contrast, are best suited for homeowners seeking a permanent, “set-and-forget” solution. The convenience of never worrying about fuel levels or refills adds to the overall enjoyment and long-term value.

Bottom Line: If your priority is a lower initial cost, flexibility, and easy setup, a propane fire pit is a practical, budget-friendly choice. If you’re looking for long-term value, lower fuel costs, minimal maintenance, and a potential boost to your home’s value, investing in a natural gas fire pit is likely the most cost-effective solution for your lifestyle. Consider your budget, how often you’ll use the fire pit, and whether you want a permanent or portable feature to make the best decision for your outdoor space.
Fuel System Components and Add-ons
Enhancing your propane or natural gas fire pit goes beyond choosing the fuel type—selecting the right components and accessories can dramatically improve both safety and enjoyment. Understanding each part of the system allows you to customize your fire pit setup for convenience, performance, and peace of mind.
Burner System
At the core of every gas fire pit is the burner system. This component is responsible for distributing the gas and creating the desired flame pattern. Burners come in various shapes and sizes, from round and square to linear designs, allowing you to match the look and heat output to your outdoor space. Find essential fire pit burner kits for both natural gas and propane setups.
