Cedar as Firewood: An In-Depth Look

I’ve spent over 20 years working with wood, from felling trees to splitting firewood. I’ve learned firsthand what burns well, what doesn’t, and what can be downright dangerous. Let’s dive into the specifics.

What is Cedar? Understanding the Wood

Cedar is a softwood known for its distinctive aroma and resistance to decay. The term “cedar” encompasses various species, including:

• Eastern Red Cedar (Juniperus virginiana): Commonly found in eastern North America.
• Western Red Cedar (Thuja plicata): Native to the Pacific Northwest.
• Aromatic Cedar (Juniperus ashei): Predominantly in the southern United States.

Each species has slightly different properties, but they share common characteristics that affect their suitability as firewood.

The Pros and Cons of Burning Cedar

Let’s weigh the advantages and disadvantages of using cedar as firewood.

Pros:

• Easy to Ignite: Cedar is resinous and full of volatile oils, making it incredibly easy to light. This is why it’s a favorite for kindling.
• Pleasant Aroma: The distinctive cedar scent is enjoyable, both when burning and when stored.
• Relatively Lightweight: Cedar is less dense than hardwoods, making it easier to handle and transport.
• Dries Quickly: Due to its lower density, cedar seasons faster than hardwoods.

Cons:

• Low Heat Output: Cedar produces significantly less heat per volume compared to hardwoods like oak or maple.
• Burns Quickly: A cedar fire burns hot but fast, requiring frequent refueling.
• Creosote Buildup: The oils in cedar can contribute to creosote accumulation in your chimney, increasing the risk of chimney fires.
• Sparks and Pops: Cedar tends to spark and pop more than hardwoods, making it less ideal for open fireplaces without a screen.

Heat Output: How Cedar Stacks Up

To put cedar’s heat output into perspective, let’s compare it to other common firewood types using the measurement of BTUs (British Thermal Units) per cord.

As you can see, cedar provides considerably less heat than hardwoods. You’ll need to burn significantly more cedar to achieve the same level of warmth.

Creosote Concerns: The Hidden Danger

Creosote is a dark, oily, and highly flammable substance that forms when wood burns incompletely. It condenses in the chimney and flue, and if it accumulates to a sufficient thickness, it can ignite, leading to a dangerous chimney fire.

Cedar, with its high resin and oil content, can contribute to creosote buildup. However, the risk can be minimized by:

5 Expert Tips for Best Burning

If you decide to burn cedar, here are five expert tips to maximize its efficiency and safety:

Tip 1: Seasoning is Key

Seasoning firewood involves drying it to reduce its moisture content. Green wood can contain up to 50% moisture, which significantly reduces its heat output and increases smoke and creosote production.

How to Season Cedar:

1. Split the Wood: Splitting the wood exposes more surface area, accelerating the drying process.
2. Stack Properly: Stack the wood off the ground in a single row, allowing air to circulate freely.
3. Choose a Sunny, Windy Location: Sunlight and wind promote evaporation.
4. Allow Sufficient Time: Cedar typically needs 6-12 months to season properly, depending on your climate.

Data Point: Studies show that seasoned firewood can produce up to 50% more heat than green wood and significantly reduces creosote formation.

My Experience: I once made the mistake of burning unseasoned cedar during a particularly cold winter. The fire was smoky, produced little heat, and left a thick layer of creosote in my chimney. It was a lesson I never forgot.

Tip 2: Mix with Hardwoods

Burning cedar alone is inefficient and can lead to rapid fuel consumption. Mixing it with hardwoods provides a more sustained and consistent heat source.

How to Mix Firewood:

• Start with Cedar: Use cedar to get the fire going quickly due to its easy ignition.
• Add Hardwoods: Once the fire is established, add hardwoods like oak, maple, or ash for longer-lasting heat.
• Layer Strategically: Alternate layers of cedar and hardwoods to maintain a steady burn.

Example: I often start my fires with cedar kindling, then add a layer of birch for quick heat, followed by oak for sustained warmth throughout the night.

Tip 3: Use for Kindling and Starter Fires

Cedar excels as kindling due to its high resin content and easy ignition. It’s perfect for getting a fire going quickly, whether in a fireplace, wood stove, or outdoor fire pit.

How to Use Cedar as Kindling:

1. Gather Small Pieces: Collect small, dry pieces of cedar, such as twigs, branches, and split pieces.
2. Arrange Strategically: Place the kindling in a teepee or log cabin formation around a fire starter (e.g., newspaper, fire starter cubes).
3. Light Carefully: Ignite the fire starter and allow the cedar kindling to catch fire.
4. Add Larger Pieces: Once the kindling is burning well, gradually add larger pieces of firewood.

Tip: I keep a basket of cedar kindling near my fireplace for easy access. It’s a lifesaver on cold mornings when I need to get a fire going quickly.

Tip 4: Monitor Your Chimney

Given cedar’s potential to contribute to creosote buildup, it’s crucial to monitor your chimney regularly.

How to Monitor Your Chimney:

• Visual Inspection: Check the chimney flue for signs of creosote accumulation, such as a black, tar-like substance.
• Professional Inspection: Schedule annual chimney inspections by a certified professional.
• Creosote Removal: If you notice significant creosote buildup, have your chimney cleaned promptly.

Warning Sign: A strong, acrid odor coming from your chimney could indicate a creosote buildup or even a small chimney fire. Take immediate action.

Tip 5: Consider the Environmental Impact

While burning firewood is a renewable energy source, it’s essential to consider its environmental impact.

Environmental Considerations:

• Sustainable Harvesting: Ensure that the cedar you burn comes from sustainably managed forests.
• Efficient Burning: Burn seasoned wood and maintain a hot fire to minimize emissions.
• Air Quality: Be mindful of air quality regulations in your area and avoid burning during periods of high pollution.

Alternative: Consider using a wood stove with advanced combustion technology, which burns more efficiently and produces fewer emissions.

Case Studies and Research Findings
