Choosing the right fire pit involves more than deciding on its size, shape, or finish. One of the most important decisions is choosing the right fuel source. For homeowners considering a gas fire pit, the two most common options are propane and natural gas. Both can provide a convenient flame and create an attractive focal point outdoors, but they differ in portability, installation, fuel availability, operating costs, and long-term convenience.
For homeowners exploring propane vs natural gas fire pits, understanding these differences can make it easier to choose a fire feature that suits their property and lifestyle. At Freedom Fire Pits, the focus is on helping homeowners create comfortable and functional outdoor spaces with fire features that fit naturally into the way they use their patios, gardens, and backyards.
What Is a Propane Fire Pit?
A propane fire pit uses liquid propane stored in a portable tank to fuel its burner. The tank connects to the fire pit through the appropriate hose and regulator, allowing the burner to produce a controlled flame. One of the biggest advantages of a propane fire pit is flexibility. Because it does not necessarily require a permanent connection to the home's gas supply, homeowners have more freedom when deciding where to position a compatible fire pit.
This makes portable propane fire pits particularly appealing for homeowners who like to rearrange their outdoor furniture, use different areas of their property, or do not have natural gas available. Propane can also be a practical choice when a homeowner wants to avoid the additional infrastructure associated with installing a permanent natural gas line.
What Is a Natural Gas Fire Pit?
A natural gas fire pit connects to a property's existing natural gas supply through an appropriate gas line. Instead of relying on a portable fuel cylinder, the fire pit receives gas directly from the home's utility connection. This provides a continuous fuel supply and eliminates the need to regularly refill or replace propane tanks.
A natural gas outdoor fire pit can be particularly convenient for homeowners who plan to keep their fire feature in one location and use it regularly. However, installing a natural gas line can require additional planning and professional installation. Local building, gas, and safety requirements should also be considered before installation.
Propane vs Natural Gas Fire Pit: What Is the Difference?
The biggest difference between propane and natural gas fire pits is how the fuel is supplied. Propane is stored in a portable tank, while natural gas is delivered through a permanent gas line. This difference affects almost everything else, including installation, portability, fuel management, and long-term use.
A propane fire pit generally offers greater flexibility because the fuel source can move with the fire pit. Natural gas provides greater convenience for a permanent setup because homeowners do not have to monitor a propane tank or arrange regular refills. Neither option is universally better; the right choice depends on how the fire pit will be used and what infrastructure is available at the property.
Is Propane or Natural Gas Cheaper for a Fire Pit?
One of the most common questions homeowners ask when comparing propane vs natural gas fire pit cost is which fuel will be less expensive over time. The answer depends on local fuel prices, how frequently the fire pit is used, and whether a natural gas line already exists near the intended installation location.
Natural gas can often have a lower ongoing fuel cost, while propane can have a lower initial infrastructure requirement. A propane fire pit may not require the installation of a permanent gas line, whereas a natural gas installation can involve additional plumbing and professional labor.
For occasional use, propane can be a practical option because homeowners only purchase fuel when they need it. For frequent use, the convenience of a continuous natural gas supply may make a natural gas fire pit more attractive. When comparing the two, consider both the initial installation expense and the expected operating cost rather than looking only at the purchase price of the fire pit.
Propane Fire Pit Operating Costs
The operating cost of a propane fire pit depends primarily on its BTU rating, the price of propane, and how long the burner operates. A higher-BTU fire pit generally consumes more propane per hour, while a lower flame setting can help extend the life of a tank.
This means homeowners who use their fire pit for several hours at a time should consider fuel consumption when selecting a model. Checking the manufacturer's BTU rating can provide a useful starting point for estimating how much propane a fire pit may use.
How Long Does Propane Last in a Fire Pit?
There is no single runtime that applies to every propane fire pit. A 20-pound propane tank can provide several hours of use, but the actual runtime depends on the fire pit's BTU output and the flame setting.
For example, a fire pit operating at a higher BTU output will consume propane faster than the same unit operating at a lower flame setting. Homeowners who frequently use their fire pit may therefore want to consider both the tank capacity and the burner's fuel consumption when choosing a propane model.
Does Propane Burn Hotter Than Natural Gas?
Propane contains more energy per unit of volume than natural gas, but that does not automatically mean every propane fire pit will produce more usable heat than every natural gas fire pit. Heat output depends on factors such as the burner design, BTU rating, flame height, outdoor conditions, and the distance between the flame and surrounding seating.
When comparing propane vs natural gas fire pit BTU output, it is more useful to look at the specifications of the individual fire pit rather than choosing a fuel type based solely on assumptions about heat.
Which Is More Portable: Propane or Natural Gas?
If portability is a priority, propane generally has the advantage. A compatible propane fire pit can operate using a portable tank, allowing homeowners to position it in different suitable areas of their outdoor space.
Natural gas fire pits are normally connected to a fixed gas line, which means the installation location is much less flexible. Once the gas line has been installed, relocating the fire pit may require additional gas-line work.
For this reason, homeowners searching for a portable outdoor propane fire pit may find propane more suitable, while those designing a permanent outdoor living area may prefer natural gas.
Can a Propane Fire Pit Be Converted to Natural Gas?
Some propane fire pits can be converted to natural gas, but not every model is designed for conversion. Propane and natural gas operate at different pressures and may require different burner components, orifices, regulators, or connections.
If you are considering converting a propane fire pit to natural gas, first check whether the manufacturer provides an approved conversion kit or conversion procedure for that specific model. A gas professional should handle the conversion and ensure the installation complies with the manufacturer's requirements and applicable local regulations.
Homeowners should never assume that a propane fire pit can simply be connected directly to a natural gas line.
Propane vs Natural Gas Fire Pit Installation
Installation is another important difference between the two fuel options. A propane fire pit generally requires a compatible propane tank and connection, while a natural gas fire pit may require a permanent gas line from the home's existing supply.
If a suitable natural gas connection is already located near the desired fire pit position, installation may be relatively straightforward. If there is no existing connection, additional work may be required. This can increase the overall cost and complexity of the project.
Because gas systems involve safety considerations, professional installation is recommended whenever permanent gas lines or fuel conversions are involved.
Propane vs Natural Gas for Fire Tables
The choice between propane and natural gas also applies to outdoor fire tables. A propane fire table can provide the appearance and functionality of a larger outdoor fire feature while retaining the flexibility of a portable fuel source. This can be useful when the outdoor layout changes or when homeowners want more freedom over the positioning of their fire feature.
A natural gas fire table, on the other hand, can provide a streamlined permanent installation without requiring a visible propane cylinder. This can work particularly well when the fire table is being incorporated into a carefully planned patio or outdoor living area.
Which Is Better for a Patio?
There is no universal answer to whether propane or natural gas is better for a patio. The decision depends on the property's existing infrastructure and how the patio will be used.
If the patio does not have a convenient natural gas connection and you want a relatively flexible solution, propane can be a practical choice. If the patio already has access to natural gas and the fire pit will remain in one location, a natural gas model may offer greater long-term convenience.
The size and layout of the patio should also be considered. Regardless of the fuel type, the fire pit should be installed and operated according to the manufacturer's clearance and safety requirements.
Propane vs Natural Gas Fire Pit Safety
Both propane and natural gas fire pits need to be used responsibly. The installation area should meet the manufacturer's clearance requirements, and the fire pit should only be operated in an appropriate outdoor environment.
Propane and natural gas also behave differently if a leak occurs. Propane is heavier than air and can collect in low areas, while natural gas is lighter than air and generally rises. Proper connections, regular inspection, adequate ventilation, and following the manufacturer's instructions are therefore important for either fuel type.
Any permanent gas-line installation or fuel conversion should be handled by a qualified professional rather than attempted as a DIY modification.
Which Should You Choose: Propane or Natural Gas?
The best choice ultimately depends on your priorities. Propane is generally the better option for homeowners who value portability, flexible placement, and a simpler fuel setup. It can be particularly useful for properties without access to natural gas or for homeowners who do not want to commit to a permanent gas connection.
Natural gas can be a better option for homeowners who want a permanent fire feature and expect to use it frequently. A continuous gas supply eliminates the need to monitor and refill propane tanks and can provide a convenient solution for a dedicated outdoor living area.
When comparing propane vs natural gas fire pits, consider the fire pit's purchase price, installation requirements, fuel costs, BTU output, portability, and expected frequency of use. Looking at the complete ownership experience will help you make a more informed decision.
Find the Right Fire Pit for Your Outdoor Space
A fire pit should fit the way you actually use your outdoor space. If you're considering propane or natural gas, the choice doesn't have to be permanent. For compatible fire pit models, switching from propane to natural gas—or vice versa—can be as simple as changing the appropriate orifice fitting. This is typically an inexpensive component, often costing $10 or sometimes $20, allowing you to change the fuel configuration without replacing the entire fire pit.
At Freedom Fire Pits, fire features are designed to help homeowners make their outdoor spaces more enjoyable and functional. Whether you're comparing a propane fire pit vs natural gas fire pit, selecting an outdoor fire table, or planning a larger outdoor living area, choosing the right fuel source is an important part of creating a fire feature that works for your space.
The goal isn't simply to choose between propane and natural gas. It's to select a fire pit that fits your lifestyle, property, budget, and long-term plans for enjoying the outdoors—with the flexibility to change fuel types when your needs change.
