Once summer is over, enjoying your backyard or patio might become a little bit challenging.
A crackling fire pit is the ultimate way to extend summer months’ warmth into the cold season, creating a cozy seating space to enjoy alone or with your loved ones.
But in addition to the extra heat, fire pits improve the ambiance in your backyard with their rustic and modern designs. Think of all the fun nights you can enjoy with the fire pit radiating heat next to you.
So, do fire pits keep you warm as they should? What factors affect the heat output produced?
Don’t worry because you’ve found this article at the right time if you’re considering installing a fire pit as I’ll explain everything you should know about them.
How Hot Is a Fire Pit?
Are you in the market for a new fire pit to install?
You want to ensure it’s good value for money and keeps you warm enough to enjoy your outdoor space in cold weather.
So, how hot can a fire pit actually be?
The heat output is measured in BTUs or British Thermal Unit. Some fire pits are designed to deliver more warmth, while others are mainly installed for aesthetic purposes.
Ideally, you need a fire pit that produces 20,000 to 50,000 BTUs to warm up a small space, while you’ll need a more efficient model that producing up to 100,000 BTUs to warm up a large space.
Some models can produce heat up to 200,000 BTUs. If you can’t tell how hot this is, just remember that the heat output of a typical stove is between 10,000 and 15,000 BTUs.
Factors that Impact Your Fire Pit’s Efficiency
Several factors affect how hot your fire pit will actually be. This is why two models might look close to one another, delivering exceptionally different results.
Fire Pit Size
As a rule of thumb, larger fire pits deliver more heat. This is mainly due to the larger fuel capacity.
Biig fire pits have bigger flames and distribute heat over a larger area, keeping your patio or backyard warm. They also come with a higher price tag, so keep that in mind.
Fuel Type and Quality
Typically, high-quality fuel types will deliver better heat.
Wood-burning fire pits offer a wide range of BTUs, depending on the wood type you’re burning.
Hardwood produces more heat than softwood because it’s more dense. It also burns cleaner.
But remember that wood isn’t the only option out there.
Natural gas fire pits don’t burn too hot, but they can be a suitable option if you already have natural gas pipes installed on your property.
Don’t have natural gas? No problem!
Propane fire pits use affordable fuel and work for portable fire tables. They also produce a high heat output.
Ethanol or bioethanol fire pits use a renewable energy source but they don’t produce a high heat output. Yet, they’re quite popular because they don’t emit any toxins.
Electric models and ethanol-burning fire pits usually contain imitation logs or stones for aesthetics.
Fire Pit Construction
Solid and thick materials like stone, concrete, and steel retain more heat, so they will have a higher heat output.
A similar fire pit that uses the same fuel type but is made of thin metal will produce a lower heat output.
If you want a durable design, masonry fire pits will work best. Steel and iron fire pits are better if you want to focus on portability.
Fire Pit Design and Location
Fully enclosed in-ground fire pits will retain more heat and contain the flames for a longer period. As a result, they will work for colder months.
On the other hand, open fire pits won’t be that warm.
The location you choose to install your fire pit also plays a crucial role in how hot it will be.
Ideally, in-ground fire pits are warmer because the flames are shielded from the wind.
This is also true if you install an open fire pit in a concealed area, protected by garden structures like trees or a nearby building.
Seating Area Design
Remember that the main purpose of investing in a fire pit is to keep your outdoor area warm. As a result, you should pay attention to the design of your seating area and how far your seats are located from the fire pit.
As you’ve already expected, when the seats are near the fire pit, you’ll definitely feel more warmth.
What are the Different Types of Fire Pits?
Choosing the fire source is the main point you’d probably consider when picking a fire pit for your patio or backyard. Here are the main types on the market.
Wood Fire Pits
With their traditional crackling campfire experience, wood-burning fire pits are a classic choice for providing outdoor warmth. A traditional fire pit will produce between 30,000 and 100,000 BTUs, depending on the type of wood used and the fire pit’s design.
Pros
- They combine the beauty of aesthetics and warming up your outdoor space.
- Different types of wood can produce an appealing smell.
- Starting the fire is easy.
Cons
- They produce a lot of ash and smoke and can be messy.
- You’ll need a wood storage area.
- You might need more work to keep your fire burning.
Natural Gas Fire Pits
Although these fire pits don’t produce a high heat output, they’ll be the best choice if you already have natural gas installed.
They’re perfect for small and medium-sized areas, producing a heat output of 30,000 to 60,000 BTUs.
Pros
- An affordable way to generate heat.
- No need to store any fuel.
- There’s no ash or a consistent need for cleanup.
Cons
- Unless you already have natural gas, the cost of installation will be high.
- These models can’t be portable because you’re restricted by the location of the natural gas pipe.
- They aren’t that warm.
Propane Fire Pits
Propane fire pits combine the advantages of wood-burning and natural gas fire pits. They produce clean fire with no ash or smoke, and the flames are high to produce more heat.
They can produce a heat output of up to 100,000 or even 200,000 BTUs, and some of the larger models allow you to conceal the gas cylinder.
Pros
- Portable design because they operate using a portable gas cylinder.
- Heat output can be adjusted.
- Clean burning with no ash or cleanup.
Cons
- Gas cylinders need to be replaced regularly.
- Propane fire pits cost more to operate than natural gas models.
Bioethanol Fire Pits
Looking for a clean and modern fire pit? Nothing beats a bioethanol fire pit.
Ethanol fire pits are suitable for heating up smaller spaces, producing an output between 10,000 and 30,000 BTUs.
Pros
- Use a renewable fuel source.
- No cleanup is needed.
- Low maintenance costs.
Cons
- These fire pits are more expensive to operate.
- They produce a lower heat output, as they’re mainly used for decorative purposes.
Electric Fire Pits
Electric fire pit models are suitable for modern setups because they lack real flames. The heat output can be adjusted, usually reaching a maximum of 20,000 or 30,000 BTUs.
Pros
- Clean operation with no toxins or ash.
- Heat output can be easily adjustable.
Cons
- Not as aesthetically pleasing as traditional wood and gas fire pits.
- Operational costs can be high.
- Suitable for smaller areas.
Final Thoughts
Fire pits can keep you warm while chilling on the patio or in your backyard.
The heat output depends on several factors, including your fire pit’s size, type, design, and location. The proximity of your seating area will also affect how warm you feel once your fire pit is on.
I’d recommend you go through the pros and cons of each type to pick the most suitable type for your outdoor space. Luckily, there are tens of models that might work for your space, and you can enjoy amazing warmth as the temperature drops.
