How Long Do Fire Pits Last? Components Breakdown

Fire pits have become a popular addition to outdoor spaces, providing warmth, ambiance, and a gathering point for friends and family. But like everything else, fire pits have a lifespan. Knowing how long a fire pit is expected to last can help you make informed decisions when choosing whether or not to install one or the type you want.

So, how long does a fire pit last? The answer is somewhere between 3 and 30 years — it all depends on what materials you choose and which type of fire pit you opt for (wood, natural gas, etc.)

In this article, we'll explore the factors that determine the longevity of fire pits, including base materials, burners, fittings, valves, accessories, and gas lines. We'll also discuss which types of fire pits tend to last longer and provide tips on prolonging a fire pit's lifespan.

Component 1: Base Material (3-30 years)

The base material of a fire pit plays a crucial role in its longevity. Different materials have varying lifespans, especially when exposed to the stress of high heat and the elements. Here's a breakdown of some common fire pit materials and their expected lifespans:

  • Steel: Steel fire pits typically last between 3 to 15 years, depending on the quality of the steel and the thickness of the material. High-quality stainless steel fire pits tend to last longer than those made from mild steel.
  • Cast Iron: Cast iron fire pits are known for their durability and can last anywhere from 15 to 25+ years with proper care.
  • Concrete: Concrete fire pits can endure for 20 to 30+ years, thanks to their resilience against heat and weather. Longevity is dependent on the quality of the concrete mix and construction.
  • Stone: Stone fire pits, if well-constructed, can last for several decades, 20+ years! Natural stone materials such as granite or sandstone tend to have a longer lifespan compared to synthetic options. Especially porous stone should be avoided, however.
  • Brick: Brick fire pits can last around 20 to 30 years when constructed correctly. The longevity may be affected by the type of bricks used and the quality of mortar.
  • Prefab Fire Pits: Prefabricated fire pits made from low-grade materials may have a shorter lifespan of around 5 to 10 years, while those constructed with high-quality materials can last up to 20 years.

It's important to note that the foundation and construction of the fire pit also impact its lifespan. Proper drainage, a stable base, and a well-built structure can significantly extend the fire pit's life.

Component 2: Burner (5-15 years)

The burner is a critical component in gas fire pits, and its lifespan can vary depending on its quality and maintenance. A well-maintained burner can be expected to last anywhere from 5 to 15 years. 

In addition to burners, there are other fire pit components that contribute to generating and sustaining the fire. These components may vary depending on the type and design of the fire pit. Here are some examples:

Fire Grate. A fire grate is a raised metal or cast iron grid placed at the bottom of wood-burning fire pits. It elevates the wood above the base, allowing air to circulate underneath, promoting better combustion, and helping to generate and maintain the fire. It is possible for a high-quality fire grate to last the lifetime of the fire pit.

Fire Rings. Fire rings are circular metal components typically found in wood-burning fire pits. They serve as a containment ring for the fire and help keep the burning wood or other fuel materials in place. Fire rings can also be long-lasting if made from quality materials and properly cared for.

Fire Rocks or Lava Rocks: Fire rocks or lava rocks are commonly used in both gas and wood-burning fire pits. They help distribute heat evenly and can assist in creating a more appealing flame pattern. These rocks generally last around 3 years if handled with care.

While burners are a significant component in gas fire pits, other components like fire grates, fire rings, and fire rocks are responsible for generating and sustaining the fire in other types of fire pits. 

Component 3: Fittings and Valves (10-15 years)

Fittings and valves are crucial for controlling gas flow in gas fire pits. Their lifespan is generally quite long, 10-15 years on average but capable of exceeding that. The specific fittings and valves required depend on the type of fire pit, whether it's propane or natural gas. 

These components are typically made from materials that are durable and resistant to corrosion, ensuring the safe and reliable operation of the fire pit. The specific materials used for fire pit valves and fittings can vary, but here are some common materials you might encounter:

Brass: Brass is a popular choice for manufacturing fire pit valves and fittings. It offers excellent corrosion resistance and is highly durable. Brass fittings and valves are often used for natural gas and propane fire pits.

Stainless Steel: Stainless steel is another common material used for fire pit valves and fittings. It is highly resistant to corrosion, rust, and heat, making it suitable for outdoor fire pit applications. Stainless steel fittings and valves are often preferred for their longevity and reliability.

Aluminum: Aluminum fittings and valves are lightweight and corrosion-resistant. While not as commonly used as brass or stainless steel, aluminum components can be suitable for certain fire pit applications.

Copper: Copper fittings and valves are known for their excellent heat conductivity and resistance to corrosion. They are sometimes used for gas lines in fire pits but are less common than brass or stainless steel.

Cast Iron: Cast iron fittings and valves are typically used in wood-burning fire pits, especially in older or traditional designs. Cast iron is robust and can withstand high heat, but it is susceptible to rust, so requires periodic maintenance.

Plastic or Polymer: In some cases, plastic or polymer fittings and valves may be used for specific gas fire pit applications. These materials are lightweight and resistant to corrosion but may have temperature limitations.

The choice of material for fire pit valves and fittings depends on factors such as the type of gas being used (natural gas or propane), the expected temperature range, and the specific design of the fire pit. It's essential to use fittings and valves that are compatible with the gas source and meet safety standards and local building codes.

When installing or replacing valves and fittings in a gas fire pit, it's crucial to follow the manufacturer's recommendations. Consult with a professional if you have any doubts about the appropriate materials and installation procedures. Proper maintenance and inspection of these are also essential to ensure the safe and efficient operation of your gas fire pit.

Component 4: Accessories (1 year to lifespan of fire pit)

Accessories like wind guards and fire glass are not typically a part of the fire pit's structural components but can enhance its functionality and appearance. Wind guards can last for many years provided they are not subjected to physical damage or extreme conditions. Fire glass can last indefinitely if it isn't broken when handling. 

Fire pit covers protect the fire pit from the elements when it's not in use. The lifespan of a cover can vary depending on its quality and exposure to harsh weather conditions. Well-made covers can last several years, but cheap ones made from less durable materials may only last a season. 

Another decorative accessory you may want to purchase is a ceramic log kit for a gas fire pit, designed to resemble a wood-burning fire. These logs are designed to withstand heat and weather, and with proper care, they can last for many years.

Component 5: Gas Line (20+ years)

For gas fire pits, the gas line is essential for delivering fuel. The expected lifespan of the gas line itself is quite long, often surpassing 20 years or more. 

However, the installation and location of the gas line can impact its longevity. Proper installation by a professional and protecting the line from physical damage can help prevent issues. Keep the gas line out of high-traffic areas or places you expect to be digging, like a garden. In areas prone to flooding or standing water, consider elevating the gas line to prevent it from being submerged, which could lead to corrosion and damage.

What Fire Pits Last Longer?

In terms of longevity, wood-burning fire pits and natural gas fire pits tend to outlast propane and gel fuel fire pits. This is because wood-burning and natural gas fire pits have fewer components that are susceptible to wear and tear, such as burners and fuel canisters. 

However, the overall lifespan of any fire pit depends on factors like materials, construction quality, and maintenance.

How to Prolong Fire Pit Life

To prolong the life of your fire pit, the most important aspect — no matter the type of pit — is routine maintenance. You should clean your fire pit regularly, removing ashes, debris, and any leftover fuel after each use. Use a cover to shield the fire pit from rain, snow, and UV rays when not in use, and inspect the fire pit for cracks, rust, or other signs of wear regularly.

Use a Fire Pit Grate 

If you have a wood-burning fire pit, we recommend using a fire pit grate or liner to protect the base from direct exposure to flames and burning wood. The grate prevents excessive heat and damage to the fire pit's interior extending its life.

Consult a Professional

For gas fire pits, it is a good idea to schedule regular professional inspections. The technician will check for gas leaks, assess burner condition, and confirm valve functionality. This way, you can address any issues promptly to ensure safe and efficient operation every time.

Avoid Accelerants 

No matter your fire pit type, you should avoid using accelerants. They produce excessively high temperatures which can lead to premature wear and tear to the fire pit components.

As you can see, the lifespan of a fire pit depends on various factors, including materials, construction quality, and maintenance practices. By selecting the right type of fire pit for your needs and following proper care and maintenance routines, you can enjoy your outdoor fire feature for many years to come!
