Is Cedar a Good Firewood Choice? Weighing the Pros and Cons

Okay, let’s get down to brass tacks. Is cedar actually good firewood? The answer, as with many things, is “it depends.” Cedar has its strengths and weaknesses, and understanding them will help you make the best decision for your needs.

The Alluring Advantages of Cedar Firewood

• Easy to Ignite: Cedar is a fantastic fire starter. The wood is relatively soft and contains natural oils that make it incredibly easy to light, even when slightly damp. I’ve personally used cedar shavings to get stubborn fires going countless times. If you’ve ever struggled to get a fire going in damp conditions, cedar is your friend.
• Aromatic Delight: That distinctive cedar smell? It’s not just pleasant; it’s a natural insect repellent! Burning cedar can help keep those pesky bugs away, especially if you’re enjoying an outdoor fire pit. I remember one summer evening when mosquitoes were swarming, and throwing a few cedar branches on the fire made a noticeable difference.
• Readily Available (in Some Regions): Depending on where you live, cedar might be abundant and relatively inexpensive. In certain areas of the Pacific Northwest, for example, cedar is a common tree, making it a more accessible and affordable firewood option compared to hardwoods that need to be trucked in from afar. This local availability can significantly reduce your firewood costs.
• Good for Shoulder Season: Because it burns hot and fast, cedar is well-suited for those in-between seasons (spring and fall) when you only need a short burst of heat. It’s perfect for taking the chill off without overheating your home. I often use cedar in my wood stove during the shoulder seasons for a quick evening warm-up.

The Drawbacks to Consider Before Burning Cedar

• Burns Quickly: This is the big one. Cedar burns much faster than dense hardwoods like oak or maple. This means you’ll need to feed the fire more frequently, and you’ll go through your wood pile much faster. Think of it like this: hardwoods are marathon runners, while cedar is a sprinter.
• Lower BTU Output: BTU (British Thermal Units) is a measure of heat energy. Cedar has a lower BTU rating compared to hardwoods, meaning it produces less heat per unit of wood. According to the Chimney Safety Institute of America (CSIA), hardwoods generally have a BTU rating of 20-30 million per cord, while cedar typically falls in the 13-17 million range. This means you’ll need more cedar to generate the same amount of heat as hardwoods.
• Increased Creosote Risk: Cedar contains resins that can contribute to creosote buildup in your chimney. Creosote is a highly flammable substance that can cause chimney fires. Regular chimney inspections and cleaning are crucial when burning cedar. I always recommend having your chimney professionally inspected at least once a year, especially if you burn a lot of softwood like cedar.
• Can Produce More Sparks: Cedar tends to spark and pop more than hardwoods, which can be a safety hazard, especially in open fireplaces. Always use a fireplace screen to prevent sparks from escaping and potentially igniting nearby materials. I’ve had a few close calls myself with stray sparks, so I always err on the side of caution.
• Not Ideal as a Primary Heat Source: Due to its fast burn rate and lower BTU output, cedar isn’t the best choice as your sole source of heat during the coldest months. It’s better suited as a supplement to hardwoods or for occasional use.

5 Expert Tips for Safe and Efficient Cedar Firewood Burning

Now that you know the pros and cons, let’s talk about how to burn cedar safely and efficiently. Here are five expert tips based on my years of experience:

1. Mix Cedar with Hardwoods for a Balanced Burn

The key to successfully burning cedar is to mix it with hardwoods. This creates a more balanced burn, combining the easy ignition of cedar with the long-lasting heat of hardwoods.

• Layering Technique: I typically layer my firewood, starting with a base of hardwoods (like oak or maple) and then adding cedar on top for easy ignition. As the cedar burns down, it ignites the hardwoods, creating a sustained fire.
• Ratio Considerations: Aim for a ratio of about 25-30% cedar to 70-75% hardwoods. This will give you the benefits of cedar without sacrificing burn time or heat output. It’s not an exact science, so experiment to find what works best for your stove or fireplace.
• Personal Anecdote: I once tried burning a full load of cedar in my wood stove, thinking I could save some money. Big mistake! The fire burned out in a couple of hours, and I ended up using twice as much wood as I normally would. Lesson learned: mixing is key!

2. Prioritize Proper Seasoning of Cedar Firewood

Seasoning firewood is the process of drying it out to reduce its moisture content. This is crucial for efficient burning and minimizing creosote buildup.

• Why Seasoning Matters: Green (unseasoned) wood contains a lot of moisture, which makes it harder to light and causes it to burn inefficiently. This moisture also creates more smoke and creosote. Seasoned wood, on the other hand, burns hotter, cleaner, and produces less creosote.
• The Seasoning Process: Ideally, cedar should be seasoned for at least 6-12 months. Here’s how to do it:
  • Split the wood: Splitting the wood exposes more surface area, allowing it to dry faster.
  • Stack it properly: Stack the wood in a single row, off the ground, with good air circulation. I use pallets to keep my wood off the ground and space the rows a few inches apart.
  • Cover the top: Cover the top of the stack with a tarp to protect it from rain and snow, but leave the sides open for ventilation.
  • Monitor moisture content: Use a moisture meter to check the moisture content of the wood. Aim for a moisture content of 20% or less. You can find moisture meters at most hardware stores for around $20-$30.
• Industry Data: According to the US Forest Service, properly seasoned firewood can produce up to 25% more heat than green wood. That’s a significant difference!

3. Maintain Your Chimney to Prevent Creosote Buildup

As mentioned earlier, cedar can contribute to creosote buildup. Regular chimney maintenance is essential to prevent chimney fires.

• Chimney Inspections: Have your chimney professionally inspected at least once a year, especially if you burn cedar regularly. A certified chimney sweep can identify potential problems and recommend solutions.
• Chimney Cleaning: Clean your chimney regularly to remove creosote buildup. You can hire a professional chimney sweep or do it yourself with the right tools. I’ve cleaned my own chimney for years, but I always wear appropriate safety gear (respirator, gloves, eye protection) and follow the instructions carefully.
• Creosote Removal Logs: Consider using creosote removal logs periodically. These logs contain chemicals that help break down creosote buildup in your chimney. While they’re not a substitute for regular cleaning, they can help reduce creosote buildup between cleanings.
• Case Study: A study by the National Fire Protection Association (NFPA) found that chimney fires are a leading cause of residential fires in the United States. Proper chimney maintenance is crucial for preventing these fires.

4. Use Cedar Sparingly in Open Fireplaces

Cedar’s tendency to spark and pop makes it less ideal for open fireplaces. If you do burn cedar in an open fireplace, take extra precautions:

• Use a Fireplace Screen: Always use a sturdy fireplace screen to prevent sparks from escaping and potentially igniting nearby materials.
• Keep a Close Watch: Never leave a fire unattended, especially when burning cedar.
• Clear the Area: Keep the area around the fireplace clear of flammable materials, such as rugs, curtains, and furniture.
• Consider Alternatives: For open fireplaces, consider using hardwoods like oak or maple, which are less likely to spark and pop.

5. Leverage Cedar for Kindling and Fire Starting

Cedar shines as a kindling and fire-starting material. Its easy ignition and aromatic properties make it perfect for getting fires going quickly and easily.

• Cedar Kindling: Use small pieces of cedar as kindling to start your fires. Cedar shavings, twigs, and small branches are all excellent choices.
• Cedar Fire Starters: You can even make your own cedar fire starters by dipping cedar cones or wood shavings in melted wax. These fire starters are incredibly effective and burn for a long time. I often make a batch of these in the fall to have on hand throughout the winter.
• Personal Tip: I keep a small basket of cedar kindling next to my wood stove for easy access. It’s a lifesaver on cold mornings when I need to get the fire going quickly.

Understanding Cedar Varieties and Their Burning Characteristics

Not all cedar is created equal. Different cedar varieties have slightly different burning characteristics. Here’s a quick overview of some common cedar types:

• Eastern Red Cedar (Juniperus virginiana): This is a common cedar variety in the eastern United States. It’s known for its strong aroma and relatively dense wood. It burns hot and fast and is excellent for kindling.
• Western Red Cedar (Thuja plicata): This cedar variety is common in the Pacific Northwest. It’s known for its lightweight wood and distinct aroma. It burns easily and is a good choice for kindling and starting fires.
• Atlantic White Cedar (Chamaecyparis thyoides): This cedar variety is found along the Atlantic coast. It’s known for its rot resistance and relatively dense wood. It burns well and is a good choice for firewood.
• Aromatic Cedar (Juniperus virginiana): This variety is basically Eastern Red Cedar, prized for its strong aromatic oils and use in closet lining and chests. The burning characteristics are the same as Eastern Red Cedar.

The density of the wood will affect the burn time and heat output. Denser cedar varieties, like Eastern Red Cedar, will burn longer and produce more heat than lighter varieties, like Western Red Cedar.

Addressing Common Concerns and Misconceptions About Burning Cedar

Let’s tackle some common questions and misconceptions about burning cedar:

• “Burning cedar is bad for the environment.” This is a common misconception. Burning any wood produces emissions, but burning seasoned wood is generally considered carbon neutral. This means that the carbon released during burning is offset by the carbon absorbed by the tree during its lifetime. However, it’s essential to burn wood efficiently and responsibly to minimize emissions.
• “Burning cedar will ruin my wood stove.” This is also a misconception. Burning cedar won’t ruin your wood stove as long as you maintain it properly and clean your chimney regularly.
• “I’m allergic to cedar. Can I still burn it?” If you’re allergic to cedar, burning it may trigger allergic reactions. Be mindful of this and take precautions, such as wearing a mask and ensuring good ventilation. If you have severe allergies, it’s best to avoid burning cedar altogether. I have a friend who is highly allergic to cedar pollen, and he avoids burning it at all costs.

The Economics of Cedar Firewood: Is It a Cost-Effective Choice?

Let’s talk about the financial side of things. Is cedar firewood a cost-effective choice?

• Price Comparison: The price of firewood varies depending on location, wood type, and supplier. In some areas, cedar may be cheaper than hardwoods, while in others, it may be more expensive. It’s essential to compare prices in your area to determine the most cost-effective option.
• BTU Considerations: Remember that cedar has a lower BTU output than hardwoods. This means you’ll need more cedar to generate the same amount of heat, which can offset any initial cost savings.
• Long-Term Value: Consider the long-term value of your firewood. While cedar may be cheaper upfront, hardwoods will last longer and provide more heat, potentially saving you money in the long run.
• Personal Example: I once calculated the cost per BTU for cedar versus oak in my area. While cedar was slightly cheaper per cord, oak was actually more cost-effective in terms of heat output. This made oak the better choice for my primary heating needs.

Sustainable Sourcing of Cedar Firewood: Ethical Considerations

It’s essential to source your cedar firewood sustainably. Here are some ethical considerations:

• Harvesting Practices: Ensure that your firewood is harvested from sustainable sources. Look for suppliers who follow responsible forestry practices and avoid clear-cutting.
• Local Sourcing: Buy firewood locally to reduce transportation costs and emissions. This also supports local businesses and economies.
• Dead or Fallen Trees: Consider using dead or fallen trees for firewood. This helps clean up the forest and reduces the need to cut down live trees.
• Avoid Endangered Species: Be sure you are not harvesting or purchasing wood from endangered or protected tree species. Check with your local forestry or environmental agencies for guidance.
