When it comes to building fires, we all think we know what we’re doing. That is—until the living room is full of smoke and the fire isn’t hot. It’s when you’re made to light a fire in order to keep warm or for ambiance and comfort for your home and family that you start to look for a better way. In the fire and chimney industry, we’ve lit more fires than we can count, and we recommend one to our customers for safety and efficiency.
Considered new in many circles, the top-down fire has been around for some time. The idea is simple. Traditionally, the kindling is placed at the bottom of the fire, then larger wood is placed on top. It ignites as the wood falls onto the fire and the flames rise larger and higher.
A top-down fire is sometimes called an upside-down fire because it is the opposite of how people traditionally light a fire. Instead of kindling at the bottom, the largest pieces are placed on the bottom. The kindling is set afire on top and gravity causes coals and flames to fall. This is the most efficient use of firewood in your home, but it is something that takes instruction and practice.
How To Build Your Top-Down Fire
Whether you have a wood-burning fireplace, insert, or stove, you should be able to build and light a top-down burn with no problem as long as your firewood is properly seasoned and split to burn.
- First, place the largest pieces along the bottom of the fireplace running from front to back.
- Second, lay wood pieces that are cut slightly smaller across the first layer.
- Third, lay pieces that are cut the smallest across the previous layer running front to back.
- Lastly, gather kindling of softwood, cut in narrow lengths or short blocks atop the fire. This top layer of the fire should be at least a few inches below the top of the door of the stove or insert. Use this space to put wood shavings and paper knots.
To prepare paper knots, roll a piece of newspaper into a tight tube and then tie in a knot. Keep several of these paper knots in your kindling box, though once your fire is lit this way, all you’ll need to do is toss more logs on to keep it going. This technique can take longer to prep but results in a blazing fire within minutes.
It’s important that before you build your fire—any fire—you have an adequate supply of properly seasoned firewood. Seasoned firewood has less water content and burns more completely than green or “wet” wood, resulting in less creosote. Building a top-down fire helps the fire to burn more completely and helps the smoke to vent more easily because it’s not fighting to rise through a bunch of wood. If you have the proper firewood, have built a top-down fire, and are using the fireplace properly (damper, doors, etc.), and the fire is still not cooperating, there may be a bigger problem with the chimney system itself.

For people looking to heat their homes efficiently with firewood, it’s a popular question: Which type of wood burns best? Indeed, some types of wood burn warmer and longer than others, but nearly any type of wood will work for a fireplace. When you choose one wood type over another, it’s not a matter of whether your home will be warm, but a matter of how much wood is needed to last you through the winter.
Hardwoods Versus Softwoods
If you are looking for wood that will put off heat for long periods of time, you will want to stock your woodpile with hardwoods. Hardwood logs take a while to be consumed by fire because of their density. However, they create hot coals that will burn intensely for hours. The drawback to hardwoods is that they take longer to become properly seasoned. Some hardwoods take as long as a year to dry adequately for burning — and they can be difficult to ignite.
Common hardwoods are valued for their fire power include oak, hard maple, hickory, birch, ash and beech. Even among common hardwoods, there are some varieties that provide more heat and burn longer than others. Sugar maples will burn longer than red and silver maples; and yellow birch will burn longer than white birch. Black cherry and elm are technically considered hardwood. The softer, commonly used hardwoods do not burn as intensely or as long as other hardwoods.
Softwoods will burn much faster and not as hot as hardwoods. However, they do have an advantage as firewood, in that they only require about six months to thoroughly season. They also are easier to ignite than hardwoods. Among the softwoods, douglas fir provides the most heat value and the longest burn. Other commonly used softwoods include hemlock, spruce and cedar. Many people avoid burning pine because it does not produce as much heat as other woods. Also, it is believed to cause creosote build-up more rapidly in the chimney’s flue.
Finding the Right Mix
In the end, finding the right wood for your fireplace is really about finding the right mix. As mentioned, both hardwoods and softwoods have advantages and disadvantages. The trick to create the perfect woodpile is to use the woods’ advantages to your advantage. Because softwoods ignite and burn quickly, they make for good fire starters. Because hardwoods will burn for a long time, they are great for sustaining your fires. That means that if you have a mix of firewood on your woodpile, you can use your softwoods to create a quick, high flame and then pile on hardwoods to keep your fire burning and providing ample heat for hours to come.
The perfect fire provides ample heat, a pleasant crackle and little smoke. Many factors can interfere with such a fire, leaving you with a fire that hisses and pops, fills your home with smoke and leaves you frustrated. A few tips can help you to build the perfect fire every time and avoid frustration.
Begin with the right tools
There are a few items you’ll need to build the perfect fire. Always start with dry, seasoned firewood. The firewood should be cut to the proper size, which is approximately three inches shorter than your firebox. You’ll need logs — split to 6 inches in diameter or less — as well as some kindling to get the fire started.
Additionally, you will need newspaper or a commercial fire starter, which is usually made of wax and sawdust. If you are using newspaper, stick to plain black and white, non-glossy pages. The newspaper can be wadded into balls or twisted into batons or knots. Finally, you will need long fireplace matches or a long lighter to safely ignite the fire.
Make sure your fireplace is ready
Never light a fire in your fireplace or wood stove unless your fireplace and chimney have been swept and inspected recently. Your fireplace also should be outfitted with a metal grate or andirons to allow air to flow around and fuel your fire. Before you build your fire, make sure your damper is open so you don’t flood your house with smoke!
Build a stable fire
Perhaps one of the most common fire-building mistakes is building a fire on a base of kindling and newspaper. As the fire burns, those bottom layers fall away, allowing the rest of the fire to collapse on top. This can create a hazard, as it can send sparks and bits of log flying, and it can compromise the quality of your burn. There are two primary methods for building a stable fire that will burn efficiently: the log cabin method and the upside down fire.
To use the log cabin method, place parallel logs approximately six inches apart across your andirons or fireplace grate. Place your newspaper or fire starter and some kindling between them. Place two more parallel logs perpendicularly across the top of the first logs, and repeat once or twice more until the fire is the desired height. Your wood stack should have a square log cabin look. Light the fire and enjoy!
As the name implies, the upside down fire takes the traditional fire building technique and flips it. You begin by placing a layer of your thickest logs along your fireplace grate. Then, you add a layer of smaller logs in the opposite direction across the top. You continue layer progressively smaller logs atop the stack until you reach the desired height. Kindling is placed on the top of the wood stack, and the newspaper or fire starter is placed on top of the kindling! Ignite the newspaper or fire starter, and the fire will burn from the top down, creating a steady fire that doesn’t need a lot of tending.

As you procure fuel for you wood-burning fireplace this fall, it’s crucial that you make sure your firewood has been properly seasoned. Properly seasoned firewood — firewood that has been dried to a water content of 20 to 25 percent — allows your fire to burn hotter and more efficiently. And when your fire burns more efficiently, it not only keeps your home warmer with less fuel, it also helps to prevent dangerous creosote from building up rapidly within your chimney flue.
How to properly season firewood
Proper firewood seasoning starts as soon as a tree is cut. Logs should be cut to fit your fireplace, about 3 to 6 inches shorter than your firebox. They should then be split to a width of 3 to 6 inches. Once cut to the proper size, the firewood should be stacked loosely so that air can circulate through the wood pile. It helps to stack wood in a sunny place where the warmth and heat of the sun will help to dry it further. At this stage, the firewood does not need to be covered. Your prepared firewood should be stored in the loosely stacked piles for 6 months to one year, depending on the size and type of the wood.
How to tell if firewood is fully seasoned
You will be able to tell your firewood is adequately dried and ready to burn by examining its color, weight and bark. Seasoned firewood will be grayish in color and will feel light for its size when picked up. The wood will be pulling away from the bark, and it may be cracked in places. If you strike two pieces of wood together, they should make a hollow sound. Once the wood is placed in your fireplace, it should light easily, and the fire should crack and pop pleasantly. If the wood is difficult to light, and if it hisses and smokes heavily when lit, its moisture content is still too high for safe and efficient burning.
How to store your seasoned firewood
Once the firewood has been fully seasoned, it is important to store it properly to keep it dry and ready for your fireplace. Seasoned firewood should be stored off of the ground in a dry place. It should be stored either under a roof or covered with a tarp. Properly storing your seasoned firewood prevents the wood from reabsorbing moisture, molding or rotting.
While properly preparing, seasoning and storing your firewood does take some extra time, it helps you to get more efficient heat from your fireplace, and it helps to keep your home safe from the dangers of creosote, which include chimney fires, carbon monoxide poisoning and foul odors. If you are purchasing your firewood from a supplier, make sure you inquire whether the firewood already has been seasoned, and check the firewood for signs that it is dry and ready for your fireplace.
