But seasoning firewood is a lot more complicated than that.
First, “a long time” is relative. It’s relative to what you perceive to be a long time. It’s relative to the wood that you are using. It’s relative to the climate and environment that your wood is exposed to during that long period of time. A long time in the case of firewood is somewhere between six months to two years! But it still depends on the firewood that you want to use.
That’s a long time to wait to use the wood you’re seasoning. But you want to make sure that you are choosing dry wood (not too dry though!). If not, then you’re creating a breeding ground for creosote to develop in your chimney. While creosote is a natural byproduct of burning wood, an excessive amount means your chimney is an accident waiting to happen since creosote is highly flammable. Excessive creosote is one of the primary contributing causes of house fires each year.
So seasoned firewood with the appropriate moisture content is where you need to start in picking your firewood. Next, you can get into the different species of trees that make the best firewood.
Why Does it Matter?
- Efficiency – Your stoves efficiency depends significantly on the type of wood you burn. For example, softwoods and oily woods may burn inefficiently, so they may not be the best type to use.
- Appearance – Choosing firewood that is from an oily tree may create thick black smoke that clouds the front glass of your wood stove.
- Reliability – They type of wood you choose could negatively affect the reliability of your wood-burning stove.
- Safety – Burning some types of wood may create a potential safety hazard in your home since they create more smoke and more creosote deposits.
Comparing By Heat Energy
Several factors affect heating fuel usage such as:
- The size of your home
- Your home’s design
- Condition of your wood stove or fireplace
- Local temperatures
- Hours that you are burning
Assuming that you use your fireplace all the time, burning when the temperatures are below 55 degrees, in Roanoke, you can expect to burn about 530 gallons of heating fuel per year! Most people don’t burn that much and can probably get away with about 275 gallons of heating fuel per year since that’s what the average size of a home fuel tank is. And that lasts a year.
The best firewoods offer the heat-energy equivalent of 200-250 gallons of fuel per cord. Then you’ll have a range of 150 to 250 gallons of fuel per cord. And finally, the lowest heat energy category produces between 100 to 150 gallons of fuel oil per cord.
200 to 250 Gallons of Fuel per Cord
Beech – Beech trees are pretty common in the Northeastern United States. The wood is dense and burns hot and clean without a lot of sparks.
Patriot Chimney Firewood Rating – 2.85
Yellow Birch – Yellow birch is identified by its silver-yellow smooth bark. The yellow birch is a hard, strong, dense wood that is used a lot in furniture making. The density helps make it a great choice for firewood.
Patriot Chimney Firewood Rating – 2.93
Hickory – Hickory is one of the top choices and considered the best choice for firewood. It’s dense and hard to split. But because of its density, hickory burns hot and stays burning for a long time. It requires about a year to season properly.
Patriot Chimney Firewood Rating – 2.95
Patriot Chimney Firewood Rating – 2.91
White Ash – Some argue that ash is the best firewood to burn during the winter. It has a low initial moisture content, just slightly above that of seasoned ash. If you’re running low on firewood, this may be a great option for you. The wood supplies good heat and splits extremely well.
Patriot Chimney Firewood Rating – 3.05
150 to 200 Gallons of Fuel per Cord
White Birch – White birch has white, thin bark with thin horizontal stripes. The bark is actually waterproof and has been used a lot in making canoes and bowls. The bark holds in the moisture, though, and makes it difficult to season. It’s important to split white birch into small sections to give the wood plenty of time to dry. White birch is a great fire starter, but you do need to make sure that the moisture content is at appropriate levels.
Patriot Chimney Firewood Rating – 1.95
Douglas Fir – Douglas fir is definitely one of the most popular softwoods to burn. Everyone would love to burn oak or maple or some other hardwoods, but it’s not exactly easy to find if the tree isn’t native to your area. Douglas fir produces decent heat and splits easily.
Patriot Chimney Firewood Rating – 2.20
American Elm – Elm provides decent heat, but I’ll get out in front and say that it’s a pain to split. The wood is very stringy and the fibers hold the wood together as the maul goes through. The wood is heavy and produces a pretty decent heat.
Patriot Chimney Firewood Rating – 2.19
100 to 150 Gallons of Fuel per Cord
Cedar – Cedar firewood is great for kindling. It is a superior wood for starting a fire. When you think of a cedar tree, you might think of its smell. It smells pretty good. That smell comes from the oil that’s found on the inside of the tree. Cedar splits really easy, even when it’s green. Cedar burns quick and hot, but also pops and sparks so it could be a fire hazard if you don’t have a screen or a glass door.
Patriot Chimney Firewood Rating – 1.71
Cottonwood – A lot of people think that cottonwood makes a poor firewood choice. Cottonwood trees are categorized as hardwood, but are relatively soft and not very dense. Because of this, it doesn’t produce very high BTUs. It also smells funny when it’s burning.
Patriot Chimney Firewood Rating – 1.65
Hemlock – It’s not the most popular choice, but it can be a great wood to burn when it’s not too cold outside, like in fall and spring. Hemlock is a softwood and like any other softwood, it’s not as popular as the hardwoods. The wood dries pretty quickly and it’s not as sappy as you might think with it being a member of the pine family. It burns hot, smells good and crackles and pops.
Patriot Chimney Firewood Rating – 1.64
Pine – People hate pine. But it’s not too bad depending on what you want to use it for. Pine is a softwood and is very sappy and full of resin. This contributes to an excessive amount of creosote buildup that you want to avoid. The best way to use pine is as kindling to start a fire. It’s easy to light and burns quickly and smells fantastic.

I took a look at each type of wood and made a note of each of the following factors:
- Nativity to Virginia
- Gallons of Fuel per Cord
- Ease of Burning
- Ease of Splitting
- Time to Season
- Heavy Smoke
- Heavy Sparks
- Cord Weight Dry
- BTUs per Cord
- Price per Cord
And then I took each of the factors, normalized the number, weighed each factor, and created an individual rating for each of the factors to create a final number that I have called the Patriot Chimney Firewood Rating.
- White Ash – 3.05
- Hickory – 2.95
- Yellow Birch – 2.93
- Red Oak – 2.91
- Beech – 2.85
- Douglas Fir – 2.20
- American Elm – 2.19
- White Birch – 1.95
- Pine – 1.84
- Red Cedar – 1.71
- Cottonwood – 1.65
- Hemlock – 1.64
How weird is that? I honestly thought that pine would’ve been in last place. I don’t like burning it and no one thinks that it should even be allowed to be burned inside the house. But that’s what happens when you build a ranking system and score it. You’ll get surprises like this.
