How Long Does A Propane Fire Pit Last – Hours Before It Runs Out?
The duration of a propane fire pit going on depends on a few factors, including the size of the fire pit, the amount of propane used per hour, and the type of fire pit.
Redoing an outdoor or indoor living space most of the time includes adding a fireplace to the ambiance. “But how long does a propane fire pit last?” is the one question all buyers ask before investing in it.
Besides the common factors like pit size, propane consumed per hour, and pit type; it is also dependent on how frequently you use the fire pit. If you use your fire pit frequently, the propane tank may need to be replaced more frequently and vice versa.
Generally speaking, a propane fire pit can last anywhere from two to four hours. On a 20-pound (or 20-lb) propane tank, the average gas fire pit will last 3 to 6 hours.
The type of fire pit also affects the length of time it will last. For example, a traditional fire pit with a metal bowl and grate will typically last the longest, while a portable fire pit with a ceramic bowl and burner will last for a shorter amount of time.
In this article, we shall cover all the important details you need to know about the fuel consumption of fire pits, the size of propane tanks to be used, the pros and cons of owning a propane fire pit, and so on.
So let’s dive in.
What Size Propane Tank Do I Need for A Fire Pit?
In order to determine what size of propane tank you will require for a specific fire pit, you will need to consider a few factors.
1. The size of the fire pit: The size of the fire pit will determine the amount of fuel that is needed to keep the fire burning. Larger fire pits will require more fuel than smaller fire pits.
2. The type of fuel being used: Propane tanks come in different sizes depending on the type of fuel being used. For example, a propane tank designed for natural gas will be larger than a propane tank designed for propane.
3. The BTU output of the fire pit: BTU stands for British Thermal Unit. It is a unit of energy that is used to measure the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
The BTU output of the fire pit will determine how much fuel is needed to keep the fire burning. Higher BTU output fire pits will require more fuel than lower BTU output fire pits.
4. The duration of the fire: The duration of the fire will also affect the size of the propane tank needed. Longer burning fires will require more fuel than shorter-burning fires.
Once you have taken these factors into consideration, you can use a propane tank size calculator to determine the size of the propane tank you will need for your specific fire pit.
The calculator will take into account the size of the fire pit, the type of fuel being used, the BTU output of the fire pit, and the duration of the fire in order to determine the size of the propane tank required.
How Much Gas Does A Fire Pit Use Per Hour?
The amount of gas a fire pit uses per hour will depend on the size and type of fire pit you are using. Generally speaking, a small fire pit will use around 1-2 cubic feet of natural gas per hour, while a larger fire pit can use up to 10 cubic feet of natural gas per hour.
Propane fire pits are slightly more efficient and can use up to 8 cubic feet of propane per hour. A propane fire pit can use anywhere from 0.5 to 1.5 gallons of propane per hour.
Smaller, less powerful pits may use less than 0.5 gallons, while larger; more powerful pits can use up to 1.5 gallons per hour.
Some important points to note are:
- The amount of gas used per hour is affected by how high the flame is set, so higher flames will use more gas than lower ones. Additionally, the type of burner used will also affect gas usage. For example, a gas log burner may use more gas than a traditional burner.
- The ambient temperature of the area where the fire pit is located will also influence how much gas is used per hour. Warmer temperatures can cause the fire to burn hotter, resulting in higher gas consumption.
- The amount of gas consumed per hour can be affected by the size and type of logs/fuel used, as well as the amount of airflow to the fire.
How Long Does Propane Tank Last for Fire Pit?
Even though this is one of the most frequently asked questions, there can be no definite answer to this. How long a propane tank lasts depends on the size of the tank, how often it is used, and the size of the fire pit.
Generally speaking, a 20-lb propane tank can last anywhere from 8 to 24 hours depending on the size of the fire pit and how long at a stretch it is used. If used continuously, it will last for 10 to 12 hours for a medium-sized fire pit.
While opting for a propane-fueled fire pit you must check the propane burning efficiency as well. The higher the propane burning efficiency of the burner, the longer the propane tank lasts. Premium burners have a minimum of 90% efficiency on average.
Here are some frequently asked questions about “how many hours does a propane fire pit last at different settings?”
1. How long will a 20 lb. propane tank last at 50,000 BTU?
A 20 lb. propane tank will approximately last anywhere between 7 to 8.5 hours at a stretch at 50,000 BTU. This implies that a 20 lb. propane tank is sufficient to last an entire evening at 50,000 BTU.
2. How long will a 20 lb propane tank last at 40,000 BTU?
A 20 lb. propane tank will approximately last anywhere between 8 to 9 hours at one stretch at 40,000 BTU. Therefore, a 20 lb. propane tank burning at 40,000 BTU can burn through the night and keep you warm.
How long will a 20 lb propane tank last at 30 000 BTU?
A 20 lb. propane tank will approximately last anywhere between 10 to 13 hours at one stretch at 30,000 BTU. This means that a 20 lb. propane tank fuelling a fire pit burning at 30,000 BTU can continue burning for two consecutive evenings if the burner maintains a decent efficiency level.
How Can I Calculate The Fuel Consumption Of My Propane Fire Pit?
The best way to calculate the fuel consumption of a propane tank used for a fire pit is to measure the amount of propane used over time.
You can do this by noting the starting and ending levels of propane in the tank, and then dividing the amount used by the amount of time it took for the propane to be used. This will give you the amount of propane consumed per hour for your specific propane fire pit.
A more generalized approach to calculate the propane consumption for all fire pits in general is:
|(Total Propane Tank BTUs / Fire Pit BTU rating) x Average propane burning efficiency of 85%|
The formula given above will directly answer the question of how long will propane tank last in fire pits of various fuel consumption rates.

How Can I Make My Propane Last Longer?
1. Use at a moderate flame – It will allow it to last longer.
2. Keep your tank full – Keeping your propane tank full will help it last longer and prevent it from becoming over-pressurized.
3. Inspect the tank regularly – Inspect the tank for dents, rust, or damage regularly. If you see any signs of wear, it’s best to replace the tank before it becomes a hazard.
4. Store the tank in a cool, dry place – Storing your tank in a cool, dry place will help keep it in good condition.
5. Keep the tank away from heat sources – Exposing your tank to heat sources can cause it to corrode more quickly.
6. Clean the tank regularly – Cleaning the tank regularly will help prevent rust and corrosion.
