Did you know that most people use their fire pits more in the fall? However, fire pits can be used during any season for some backyard fun.
If you plan to use a fire pit this year, you’ll need to think about what type of fuel you want to use. The most common choices are wood, gas and charcoal but they’re not the only options. Which one is the best? It really depends on what you’re looking for in a fire pit or fireplace experience.
Each type of fuel has its own set of pros and cons, and you’ll need to decide what type of fuel you want to use before purchasing your fire pit. Keep reading and we’ll explore the different fuel types for fire pits and their advantages and disadvantages.
What Type of Fire Pit Fuel is Best for You?
There are a number of things to keep in mind when deciding what type of fuel to use for your fire pit or outdoor fireplace. Aesthetic appeal is subjective, but some other objective characteristics include:
- Heat
- Burn time
- Cost
- Safety
- Ease of use
- Availability
What Amount of Heat is Produced by the Fuel?
How hot do you want your fire pit to burn? If you plan to have winter fires, you’ll want something that burns a little hotter. The amount of heat produced by a fuel is determined by its caloric content. The higher the caloric content, the more heat it produces. Different fuels have different caloric content, so not all fuels generate the same heat. Wind chill and environmental temperature all impact the amount of heat you’ll need or want from your fire pit fuel.
How Long Do You Want Your Fire Pit Fuel to Burn?
If you’re new to fire pits, you may wonder how long your fuel should burn. The answer to this question depends on a few factors, including the purpose of the fire pit and how frequently you want to replenish the fuel. There’s a big difference between needing heat for a couple of hours while you enjoy a drink and hosting a party that goes deep into the night. It also matters if you expect to be sitting the whole time or walking around.
‘What is the Cost of the Fuel?
One of the most important factors in evaluating fire pit fuel options is the cost. If you don’t want to burn through your hard-earned cash, you need to compare both short and long-run fuel costs. Some options require potentially expensive installations, while others frequently need to be replenished or are simply expensive solutions. If you only occasionally need a fire pit, it might not matter much. If you plan to have frequent outdoor activities in the space, it’s a much more important consideration.
Which Fuels are Safer for Your Setting?
Your specific environment determines which fuels may be safer to use than others. Some require uncovered and well-ventilated spaces, while others become more dangerous in windy conditions or when flammable materials are in close proximity to the fire pit. The presence of pets and kids is also a consideration as thermal burns are one of the most preventable injuries sustained by small children and adolescents. [Flaherty & Sheridan (2019)]
How Easy is it to Manage and Clean Up Fires Generated by the Fuel?
What is the Availability of the Fuel?
Depending on your location and the time of year, some types of fuel may be easier to find or purchase than others. Obviously, cold Winter months are when there’s likely to be the highest demand, so you might want to stock up in advance. Traditional fuels are apt to be more readily available than some newer ones. Additionally, global or domestic supply chain issues can also result in longer lead times for retail outlets to restock certain fuels, so it’s good to know where the fuel is sourced.
Primary Types of Fuel for Your Fire Pit
Are you ready to choose the right fuel for your fire pit? Check out some common options.
Seasoned Wood
If you’re looking for a more traditional fire pit fuel, seasoned wood is a great option. Seasoned wood is simply wood left out to dry for a period of time – typically six months or more.
This type of wood burns hotter than gas fuels and produces longer-lasting flames than non-seasoned wood, making it a great choice for cold winter nights. It’s easy to find at hardware and grocery stores and is usually inexpensive. However, wood burns quickly relative to other fuel options and needs frequent replenishing.
However, there are a few things to keep in mind when using seasoned wood. First, it’s important to use only fully dry seasoned wood that ideally has been cut into small pieces. Avoid using green wood, as it produces more smoke and could contain moisture that can cause the fire to flare up. Second, because seasoned wood burns so hot, it’s important to use a larger fire pit to keep the flames at a distance from curious little hands or paws. Third, if you do choose to use a wood-burning pit, make sure it’s properly ventilated.
Another downside to using wood is that it can be messy and take a lot of time to clean up after you’re done with the fire pit. Ashes and embers need to be dowsed with water and swept up so they don’t present a danger or dirty up your outdoor setting.
Propane
Liquid propane is one of the most popular types of fuel used in fire pits and it comes in the familiar tanks often seen connected to Weber Grills and other barbecues.
Propane gas is a clean-burning fuel that produces less heat than wood or coal, but enough to keep you warm on a cool night. When you’re heading inside and no longer need the fire, simply turn the valve to shut off the flow of gas. There’s no mess to clean with propane, although there may be an odor depending on the ventilation.
Propane tanks come in different sizes and can be refilled or replaced when they run out, making them a convenient option for long-term use. While you can usually find them at most hardware stores as there are rarely propane shortages, shipping delays and a lack of tanks can make it more difficult to come by if you live in smaller towns or off the beaten path.
However, there are a few downsides to using propane in your fire pit. First, as a compressed gas, it can be dangerous if not stored and used properly. Second, it can be expensive to keep refilling your tank. But if you’re looking for a clean-burning, easy-to-use fuel for your fire pit, propane is a great option.
Natural Gas
If you’re looking for an odorless and clean-burning fuel for your fire pit, natural gas is a great option.
There are a few things to keep in mind if you choose natural gas for your fire pit. First, you’ll need a natural gas line to connect to or a tank. If you don’t have an existing gas line running to your home, it should be installed by a professional and can be costly. However, once the line is installed, natural gas is usually one of the most cost-effective fuels and you never have to worry about running out. Otherwise, you will need to purchase a tank of natural gas and have it delivered to your home.
Second, natural gas is a fossil fuel, so it’s not the most environmentally friendly option. If you’re looking for a green option for your fire pit, consider using bioethanol instead.
Natural gas fire pits are typically easy to control and are a safer option than wood-burning pits. They don’t produce smoke and embers, so you won’t have to deal with smoky clothes or ashes afterward. However, they produce less heat than wood or propane.
Bio-Ethanol
Ethanol is a type of alcohol that’s derived from plant sources. It can be used as a fuel for fire pits and it has some advantages over other types of fuels.
One advantage of ethanol is that it burns cleanly. This means that it produces little to no smoke or soot, which can be a problem with other types of fuels. This smokeless fuel is a great option for spaces with shifting breezes and for people who want to enjoy their fire pit without worrying about smoke. Bio-ethanol is also a good choice for those who have respiratory issues or are sensitive to smoke. It also requires less ventilation than gas alternatives, allowing it to be used indoors and outdoors.
Another advantage of ethanol is that it is renewable. This means that it can get produced from plant sources that are replenishable, unlike fossil fuels like coal or oil.
However, there are also some disadvantages to using ethanol as a fuel for fire pits. One disadvantage is that it can be more expensive than other types of fuel. Another disadvantage is that it may not produce as much heat as other types of fuels. Additionally, unlike propane or natural gas which can be housed away from the fire pit, bio-ethanol is poured into the fire pit burner itself. Depending on the size of the fire pit, it may require frequent refilling as the fire burns out. Lighting bio-ethanol may require a little finesse and a lot of care but you won’t have to worry about blowing embers or messy clean-up when you’re done.

Secondary Fuels for Outdoor Fire Pits
Gel Fuel
Gel fuel is an alcohol-based fuel that is often used in fire pits. It’s easy to use and you can buy it at most home improvement stores.
The main downside of gel fuel is that it can be expensive. However, gel fuel will typically burn for two to three hours. It also lights up quickly and is easy to use.
Charcoal
If you’re looking for a more natural way to fuel your fire pit, charcoal may be the way to go. Charcoal is made from wood that has been burned in a low-oxygen environment, which results in a more efficient burn.
There are two types of charcoal: lump and briquettes. Lump charcoal is made from whole pieces of wood that have been burned down, while briquettes are made from sawdust or other wood waste that’s compacted and held together with binders. Lump charcoal is generally considered the better option as it burns hotter and cleaner than briquettes. However, it can be more expensive and difficult to find. Briquettes are more commonly found at your local hardware store but they don’t burn as hot or clean as lump charcoal.
Charcoal burns hotter and longer than wood, so you won’t need to add as much during your session – making it great for large gatherings. However, it can be more expensive than wood and is relatively messy. Sparks from charcoal briquettes can easily ignite dried grass or leaves. If you must use them, be sure to keep them away from the edge of the pit and extinguish them completely when you’re done.
Wood Briquettes
Wood briquettes are made from sawdust or other wood waste and they are compressed into a solid block.
Briquettes have a high density and burn slowly, so they are often used in place of logs in fire pits. Briquettes also produce less smoke than logs and may be a better option for people who are sensitive to smoke.
There are some downsides to using wood briquettes in a fire pit. One is that they can be messy to handle since they tend to break apart easily. [Baker (1982)] Another is that it can be difficult to find briquettes that are made from sustainable or recycled materials. And finally, briquettes may not produce as much heat as other types of wood fuels.
Wood Pellets
Wood pellets are made from compressed sawdust and other wood waste and they are a renewable resource.
Pellets can be bought in bulk or by the bag and they burn cleaner than wood logs. The downside to using pellets is that they can be more expensive than other types of fuel and they can create ash that will need to be disposed of once you no longer need a fire.
