Fire pits have become an essential addition to homes, transforming outdoor entertaining throughout the year. They provide warmth on chilly nights and offer the perfect setting for roasting marshmallows. Additionally, there is a therapeutic element in simply sitting and mesmerizingly watching the flickering flames. But how hot does a fire pit get?

It depends on the specific type of fire pit you own and the fuel you choose to burn.

A fire pit can reach temperatures ranging from 1,200 to 1,600 degrees Fahrenheit (650 to 870 degrees Celsius), depending on factors such as the type of fuel used and the airflow within the fire pit.

Factors Affecting Heat – How Hot Does A Fire Pit Get?

1. Temperature Considerations

The structure and materials used in constructing a fire pit significantly influence the temperatures it can attain. To build a fire, three essential components are required: fuel, oxygen, and heat.

When these elements combine, a chemical reaction occurs, resulting in the production of heat. For instance, wood needs approximately 16% oxygen to burn. As air naturally contains 21% oxygen, a well-formed wood fire is capable of generating extremely high temperatures.

In fact, a bonfire can reach scorching temperatures of up to 2012 degrees Fahrenheit (1100 degrees Celsius), which is sufficient to surpass the melting point of aluminum (you may also be interested in how to make a bonfire pit)

2. Different Varieties

Fire pits come in a wide variety of styles, sizes, and materials. You can opt for a lightweight metal bowl that can be easily placed anywhere or a fixed masonry structure ideal for patio gatherings.

The choice of the right product for you depends on factors such as frequency of use, placement location, budget constraints, and local regulations (read: Can you light a fire in your backyard without getting burned?).

It’s amazing to reflect on how we managed before fire pits became so popular!

3. Fuel Options

Some fire pit owners swear by crackling wood fires despite the accompanying smoke and ash. Others find the convenience of instant and controllable flames by simply flipping a switch more appealing.

While most fire pit styles blend well with lawn corners, those made from mortar masonry or tumbled concrete pavers tend to harmonize better with existing stonework when incorporated into a patio setting.

Choosing The Right Fuel Type

Similar to the diverse range of fire pits available, various fuel options cater to specific fire pit types.

Heat output in fire pits is measured in BTUs (British Thermal Units), a universal unit used to classify the heat generated by a range of products such as barbecue grills, fire pits, water heaters, and air conditioners.

Wood, charcoal, smokeless coal, fireplace ethanol, and gases like propane are all common fuel choices for fire pits.

Let’s explore the suitable fuel type that meets your heating needs.

How Hot Does A Wood Fire Pit Get?

Determining the exact temperature of wood fires is challenging due to the numerous variables that affect the heat generated from burning wood. Consequently, manufacturers rarely specify the heat produced by their wood fire pits as it would be an arbitrary figure.

However, existing data on wood fire temperatures can be used to estimate the heat output of a wood-burning pit. It is a well-known fact that fire bowls fueled primarily by wood reach higher temperatures compared to gas burners.

Wood burning entails two types of heat: the flames produced during wood combustion and the radiant heat emitted by the glowing logs and embers.

The temperature attained when burning wood can exceed 1000 degrees Fahrenheit, and the heat output can easily exceed 100,000 BTUs. These figures are influenced by the size of the fire bowl and the airflow surrounding the fire.

A larger fire bowl results in bigger flames and higher heat output. Adequate airflow also contributes to higher heat levels. Therefore, the position of your outdoor fire pit is a crucial factor in determining the amount of heat generated.

A centrally positioned fire pit will provide more warmth than one placed to the side or tucked away in a corner (here’s how far should a fire pit be from a house).

How Hot Does A Fireplace Get?

Gas fire pits utilizing bioethanol fuel are primarily designed for decorative purposes and are not recommended for outdoor use. These fire pits are usually smaller in size, resulting in a lower fuel capacity, smaller flames, and reduced heat output ranging from 1000 to 4000 BTUs.

While this amount of heat can create a cozy feeling inside an entertainment room, it may struggle to provide sufficient warmth if used outdoors, particularly on colder evenings.

How Hot Does A Propane Fire Pit Get?

Compared to wood-burning fire pits, those powered by propane are easier to ignite, offer controllable heat, and require minimal cleanup. Manufacturers of propane-fueled products typically advertise their heat ratings to compete in the market.

On the lower end of the scale, decorative propane fire pits produce around 10,000 BTUs, prioritizing style as much as heat generation. Moving up the scale, a range of propane fire pits is capable of reaching much higher temperatures.

The maximum heat output for a domestic gas-fueled product usually reaches approximately 70,000 BTUs.

How Hot Does A Gas Fire Pit Get?

Unlike propane, a gas fire pit is stationary as it is connected to a gas line from your house (find out how to light a gas fire pit).

Natural gas is approximately 1/6th the cost of propane in some regions and provides the advantage of an uninterrupted fuel supply.

However, propane is more efficient, generating about 2500 BTUs, while the same amount of natural gas produces only 1000 BTUs.

Fire Pit Costs

The price of fire pits varies depending on their specifications.

A 28-inch steel wood fire bowl can be purchased for as low as $50, while propane-burning fire pits typically start around $500 for a 46-inch model. Custom masonry fire pits of similar size can cost around $2,500.

Safety Measures For Using Your Outdoor Fire Pit
