There’s something incredibly inviting about sitting around a warm fire on a cool evening, but nobody enjoys sitting in a cloud of smoke.
That’s where smokeless fire pits come in. But are smokeless fire pits really completely smokeless? The short answer is not always. A smokeless fire pit is designed to significantly reduce visible smoke by burning the smoke and gases produced by the fire through a process called secondary combustion.
When used correctly, a Wizard Fire Pit can produce a clean-burning flame with very little visible smoke. However, the type of wood you use, how you light the fire, and how you manage the airflow can all make a big difference.
Here’s what you need to know.
What Does “Smokeless” Actually Mean?
A smokeless fire pit doesn’t mean that absolutely zero smoke will ever be produced.
Instead, the design is intended to burn the smoke that would normally escape from the fire. As the fire gets hot, the smoke and gases rise through the fire pit and are reheated. Additional oxygen is introduced through the upper holes, allowing these gases to ignite.
This process is known as secondary combustion.
The result is a hotter, more efficient fire with significantly less visible smoke compared with a traditional open fire.
How Does a Wizard Fire Pit Reduce Smoke?
The Wizard Fire Pit is designed around secondary combustion.
As the fire burns, hot gases and smoke rise through the fire pit. When the fire is hot enough and there is sufficient airflow, these gases are burned again as they reach the upper holes.
You can often see this happening as a ring of flames around the inside of the top of the fire pit.
This is one of the reasons the Wizard can produce such an impressive flame while keeping visible smoke to a minimum.
Keep the Airflow Fully Open
One of the simplest things you can do to help your Wizard Fire Pit burn cleanly is to make sure the airflow is set correctly.
When starting your fire, we recommend leaving the airflow lever fully open on the “+” setting.
The extra oxygen helps the fire establish itself and supports the secondary combustion process.
You may notice that the fire burns hotter and uses wood a little faster with the vent fully open. This is normal. A hotter, more efficient fire is an important part of achieving that cleaner-burning flame.
The Wood You Use Really Matters
If your fire pit is producing more smoke than expected, the first thing to check is your firewood.
We recommend using dry wood, with hardwoods being an excellent choice. Manuka, Kanuka, Oak, Applewood, and Pōhutukawa can all work well.
Why Avoid Pine?
Pine can be tempting because it is often inexpensive and readily available, but we advise against using it as your main fuel.
Pine has a high resin content, which can cause it to produce heavy black soot and more smoke when burned.
If you want to get the best performance from your Wizard Fire Pit, choosing good-quality, dry firewood is one of the easiest improvements you can make.
Keep the Fuel Below the Top Holes
Another important part of achieving secondary combustion is how you load the fire pit.
Try to keep your fuel below the line of the holes around the top of the fire pit.
Those holes play an important role in the secondary combustion process. If your logs are sticking above the holes, the smoke-burning effect cannot work as effectively.
Once the fire is established, add wood gradually rather than completely filling the fire pit.
What About Compressed Wood Pellets?
Wizard Oak Hardwood Pellets are a convenient fuel option made from 100% oak hardwood, with no fillers or binders. They provide a consistent, clean-burning fuel and are especially handy for the Mini or Small Wizard or as starter fuel in larger models. They can also be used for cooking and combined with larger pieces of hardwood.
What About Fire Starters?
Wizard Fire Starters make lighting your fire quick and easy. Use a couple of natural fire starters to help get your wood or pellets burning, then allow the fire to build up and reach the temperature needed for secondary combustion.
It’s normal to see some smoke while the fire is getting started. Once the fire becomes hotter and established, visible smoke should reduce significantly.
Why Is My Fire Smoky When I First Light It?
It’s normal to see some smoke while a fire is getting started.
A cold fire hasn't reached the temperature required for effective secondary combustion yet. As the fire becomes hotter and the wood begins burning more efficiently, visible smoke should reduce.
If the fire remains very smoky after it has become established, check:
- Is the wood completely dry?
- Are you using pine?
- Is the airflow lever fully open?
- Is the fuel below the line of the top holes?
- Is the fire hot enough for secondary combustion to occur?
Making adjustments to these areas can make a significant difference.
Smokeless Doesn't Mean Smoke-Free in Every Situation
Even a well-designed smokeless fire pit can produce some smoke under certain conditions.
For example, adding a large amount of fresh wood to an established fire can temporarily create smoke while the new fuel heats up. Damp wood can also produce considerably more smoke than dry wood.
The goal of a smokeless fire pit is to minimise visible smoke once the fire is hot and operating correctly, rather than guarantee that smoke will never appear under any circumstances.
More Heat, Less Smoke
Secondary combustion isn't just about reducing smoke.
Because more of the wood's gases are burned rather than released as smoke, the fire can burn more completely and efficiently. This helps create a hotter, more enjoyable fire.
The majority of the heat from a Wizard Fire Pit comes through the top opening, creating a beautiful column of flame and warmth.
For those looking to direct more warmth outward toward their seating area, the optional Heat Deflector for the Regular Fire Pit is designed to help magnify and direct heat outward.
Choose the Right Fire for Your Evening
Not every fire needs to be roaring.
For a relaxed evening with two people, you may want a smaller, controlled fire. For entertaining friends or family, you may want a larger fire that provides more warmth and creates a bigger focal point.
The Wizard Fire Pit range includes four sizes, Mini, Small, Regular, and Jumbo, making it easier to choose a fire pit that suits your space and how you plan to use it.
Whether you're enjoying a quiet evening outside or gathering everyone around the fire, the same principles apply: use dry fuel, provide plenty of airflow, and allow the fire to get hot enough for secondary combustion.
A Cleaner Way to Enjoy the Fire
So, are smokeless fire pits really smokeless?
They can be remarkably low-smoke when used correctly, but “smokeless” doesn't mean absolutely zero smoke in every situation.
With the right fuel, proper airflow, and enough heat for secondary combustion, a Wizard Fire Pit can produce a beautiful, efficient flame with significantly less visible smoke than a traditional open fire.
And that's what makes sitting around the fire even more enjoyable, less smoke in your face, more warmth, and more time spent enjoying the people around you.
Choose good wood. Open the airflow. Keep the fuel below the top holes. Let the fire get hot, and enjoy the flames.
