Natural Gas vs Liquid Propane: The Best Fuel Choice for Your Custom Outdoor Fire Table

Creating an outdoor sanctuary in Southwestern Ontario requires careful planning, especially when it comes to your heat source. Whether you are overlooking Lake Huron in Sarnia or enjoying a quiet backyard in Strathroy, the right fire feature defines your space. The most common debate among homeowners centers on a natural gas vs propane fire table. This decision impacts your budget, your backyard design and your overall enjoyment of the space for years to come.

Many people start their search looking for the most beautiful unit, but they quickly realize that fuel logistics dictate the design. Choosing a fuel source isn’t just about how you turn the fire on. It is about how often you want to think about your fireplace after it is installed. By understanding the mechanical and financial differences between these two options, you can avoid the common pitfalls of outdoor renovations.

 

Understanding the Core Differences in Fuel Types

Natural gas and liquid propane are both excellent fuels for outdoor heating, but they behave differently under pressure. Natural gas is lighter than air and is delivered directly to your home through a utility line. Propane is a compressed liquid that is heavier than air and is typically stored in portable 20-pound tanks. These physical properties influence everything from burner design to safety requirements.

When you choose a natural gas setup, you are investing in a permanent utility. This fuel source is always available at the flip of a switch or the turn of a key. You never have to worry about the flame flickering out during a dinner party. On the other hand, propane is the king of versatility. If you want to move your fire table from the pool deck to the patio for different events, propane allows that freedom without requiring a gas technician to move lines.

The Endless Supply of Natural Gas

The primary reason homeowners in London and Sarnia opt for natural gas is the sheer convenience of an unlimited supply. There is a specific peace of mind that comes with knowing your fire table is connected to the same reliable grid that heats your home and cooks your food. You effectively eliminate the chore of monitoring fuel levels. This makes natural gas the gold standard for those who use their outdoor spaces frequently.

Because natural gas is piped into the house at a consistent pressure, the flame height remains stable regardless of how long the unit has been running. This is a significant advantage over propane tanks, which can lose pressure as the liquid level drops or when the temperature outside plummets. In the brisk evenings of an Ontario autumn, a natural gas line ensures your fire burns as bright at midnight as it did at dusk.

The High-Heat Density of Liquid Propane

If your goal is maximum warmth per cubic foot of fuel, propane often takes the lead. Propane contains more British Thermal Units (BTUs) per volume than natural gas. This makes it a contender for the best fuel for high-heat outdoor fire table performance, especially in compact units. Because it is more energy-dense, a propane burner can often produce a very intense heat signature quickly.

However, this high energy density comes with a trade-off. To achieve those high temperatures, you will consume fuel at a rapid rate. A standard 20-pound propane tank typically lasts between 8 and 12 hours, depending on the BTU rating of your table. For homeowners who enjoy hosting long gatherings, “tank anxiety” is a real concern. Nothing kills the mood faster than having to disconnect a frosted tank in the dark to find a spare in the garage.

Best Fuel for High-Heat Outdoor Fire Table Performance

When evaluating performance, you must look at how the burner handles the fuel. Natural gas burners typically have larger orifices to accommodate the lower pressure and lower energy density of the gas. This results in a large yellow dancing flame that looks very traditional and inviting. Propane burners are tuned for higher pressure, which can sometimes lead to a slightly bluer flame if the air-to-fuel mixture is not perfectly balanced with decorative media like lava rock or glass.

Performance is also about the “warmth radius.” In the wide-open backyards of Southwestern Ontario, wind can easily dissipate heat. A high-heat unit is essential for comfort. While propane is dense, natural gas allows you to install much larger burners with higher total BTU outputs because you aren’t limited by the flow rate of a small tank regulator. If you want a massive five-foot linear fire feature, natural gas is usually the only practical way to fuel it properly.

Solving the “Tank Anxiety” and Maintenance Hurdle

The maintenance of a fire feature should be minimal. With a natural gas line, the only maintenance is the occasional cleaning of the burner ports and clearing out debris or spider webs. There are no heavy tanks to lift and no trips to the gas station or local hardware store for refills. For many, this convenience justifies the upfront cost of the gas line installation.

Propane users must be more hands-on. Beyond the physical lifting of 40-pound full tanks, you also have to manage the storage of spare tanks. In Ontario, safety regulations dictate that propane tanks must be stored outdoors in a well-ventilated area and never inside a garage or shed. This adds a layer of logistical planning to your property maintenance that many homeowners find tedious over time.

Aesthetics vs. Utility: Hidden Lines or Hidden Tanks?

Designers often prefer natural gas because it allows for a cleaner look. A gas line is buried underground and comes up directly through the center of the fire table base. This means no visible hoses and no bulky access doors. You can choose ultra-slim or low-profile fire table designs that would be impossible to build if they had to house a large propane tank inside.

If you choose propane, you have two aesthetic choices. You can buy a table with “internal tank storage,” which usually means the table must be at least 24 inches tall to fit the tank. This can limit your design options if you prefer a low-slung coffee table style. Alternatively, you can use an external tank with a long hose, which creates a tripping hazard and requires a “tank hide” cover that looks like a side table. Neither is as seamless as a direct gas connection.

The visual impact of a fire feature is a key part of creating a relaxing environment. Many homeowners find inspiration in lifestyle blogs that emphasize the importance of a clean, clutter-free hearth. As noted in a popular piece on the psychology of fireplaces, the visual elements of a fire are just as important as the physical warmth for creating a sense of well-being. A messy propane hose can detract from that mental escape.

Permanent Infrastructure vs. Flexible Backyard Design

Natural gas is a commitment. Once the line is trenched and the table is bolted down, that is where it stays. This is perfect for custom outdoor kitchens or professionally landscaped patios where the layout is fixed. It adds long-term value to your home because it is considered a permanent improvement to the property’s utility.

Propane offers the “flexible design” advantage. If you are a renter or if you plan on redesigning your landscaping in a few years, propane is the way to go. You can take your fire table with you when you move or reposition it to different areas of the yard as your needs change. For some families, the ability to move the fire closer to the house in the winter and further into the yard in the summer is a winning feature.

Analyzing the Cost of Installation and Operation in Ontario

The financial comparison is a tale of two halves. Natural gas has a high upfront cost but very low running costs. In London or Sarnia, hiring a licensed gas fitter to run a line from your meter to a backyard fire pit can cost anywhere from $500 to $2,500, depending on the distance and the complexity of the trenching. However, once installed, natural gas is significantly cheaper than propane per hour of burn time.

Propane has a nearly zero upfront cost. You buy the tank and the table, and you are ready to go. However, you will pay a premium for fuel. A typical propane refill can cost $20 to $30. If you use your fire table three times a week during the summer, you could easily spend $300 to $500 a year on fuel. Over a five-year period, the natural gas line often pays for itself through these fuel savings alone.

Safety and TSSA Compliance for Southwestern Ontario Homes

In Ontario, all gas installations fall under the jurisdiction of the Technical Standards and Safety Authority (TSSA). This is not an area for DIY projects. A natural gas line must be installed by a technician with a valid G2 or G1 license to ensure it is buried at the correct depth and uses approved piping materials. This ensures your home insurance remains valid and your family stays safe.

Propane also carries safety responsibilities. Because propane is heavier than air, it can pool in low-grade areas or inside the base of a fire table if there is a leak. This creates an explosion hazard. It is vital to ensure your propane fire table has proper ventilation holes in the base to allow any leaking gas to escape. Regular inspections of the hose and regulator for cracks or “O-ring” wear are essential parts of propane ownership.

Making Your Final Selection

Deciding between a natural gas vs propane fire table ultimately comes down to your lifestyle. If you value convenience and plan to stay in your home for a long time, natural gas is the undisputed winner. It offers a seamless look, a constant fuel supply and lower operating costs. It transforms your backyard into a true extension of your living room.

If you prefer flexibility, have a limited initial budget or live in a rental property, propane provides an immediate solution. It allows you to enjoy the luxury of an outdoor fire without the need for permanent construction. Both options will significantly enhance your outdoor living experience, provided you choose a high-quality unit designed for the Canadian climate.

FAQs

1. Can I convert a propane fire table to natural gas later? Most high-quality fire tables offer conversion kits. This usually involves changing the burner orifice and adding a natural gas hose and regulator. However, you should always check the manufacturer’s specifications before purchasing to ensure the unit is “dual-fuel” compatible.

2. How deep does a natural gas line need to be buried in Ontario? According to TSSA standards and the Ontario gas code, lines are typically buried 12 to 18 inches deep, depending on the soil type and whether the line is under a walkway or a garden. Always call before you dig to locate existing utilities.

3. Does a natural gas fire table add value to my home? Yes. Permanent outdoor gas features are highly attractive to buyers in the Ontario real estate market. They are seen as luxury upgrades that make the backyard a more functional living space.

4. Why is my propane tank freezing up when the fire table is on? As propane turns from a liquid to a gas, it absorbs heat. If you are running a high-BTU burner for a long time, the tank can chill to the point where frost forms on the outside. This can cause the flame to drop. Switching to a larger tank or a natural gas line solves this issue.

5. How much does it cost to run a natural gas fire table per hour? Depending on current utility rates in London or Sarnia, running a standard fire table on natural gas usually costs less than $1.00 per hour. This is significantly cheaper than the $2.50 to $4.00 per hour cost of propane.
