Can You Burn Cedar Wood in a Fireplace? (5 Expert Tips)

Let’s be honest, there’s something deeply satisfying about a crackling fire on a chilly evening. The warmth, the smell, the ambiance – it’s pure comfort. And that brings us to cedar. Can you burn cedar wood in a fireplace? The short answer is yes, but with a few crucial caveats. And that’s where my experience comes in.

I’ve spent years knee-deep in sawdust, managing firewood operations, and helping folks optimize their wood-burning setups. I’ve learned firsthand the difference between a safe, efficient fire and a smoky, potentially dangerous one. Burning cedar isn’t inherently bad, but understanding its unique characteristics is key. This article dives deep into the pros and cons of burning cedar, offers expert tips for safe and efficient burning, and even helps you navigate the sometimes-tricky costs associated with sourcing and processing cedar firewood.

Understanding Cedar: A Unique Wood

Cedar is often prized for its aromatic qualities and insect-repelling properties, making it a popular choice for closets and outdoor furniture. But these same characteristics influence its performance as firewood.

Resin Content: Cedar contains a higher resin content than many other hardwoods like oak or maple. This resin is what gives cedar its distinctive smell, but it also means it burns hotter and faster, and produces more smoke and creosote.
Density: Cedar is a relatively soft wood compared to hardwoods. This lower density translates to a quicker burn time and less heat output per unit of volume.
Types of Cedar: The term “cedar” encompasses a variety of species, including Eastern Red Cedar, Western Red Cedar, and Atlantic White Cedar. Each species has slightly different burning characteristics. For instance, Western Red Cedar, commonly used in construction, tends to be less dense than Eastern Red Cedar.

The Pros and Cons of Burning Cedar

Before you load up your fireplace with cedar, let’s weigh the advantages and disadvantages:

Pros:

Easy to Ignite: Cedar’s high resin content makes it incredibly easy to light, making it an excellent kindling wood.
Pleasant Aroma: The distinctive cedar scent is a definite plus for many people, adding to the ambiance of a fire.
Insect Repellent: Burning cedar can help repel insects, although the effect is localized to the immediate vicinity of the fire.
Fast-Burning: Ideal for a quick fire to take the chill off a room.

Cons:

High Creosote Production: This is the biggest concern. Creosote is a flammable byproduct of incomplete combustion that can build up in your chimney and cause a chimney fire.
Sparks and Popping: Cedar tends to spark and pop more than hardwoods, increasing the risk of embers escaping the fireplace.
Lower Heat Output: Due to its lower density, cedar doesn’t provide as much sustained heat as hardwoods.
Faster Burn Rate: You’ll need to replenish the fire more frequently with cedar compared to denser woods.

Expert Tip #1: Seasoning is Key – Patience Pays Off

Like all firewood, cedar needs to be properly seasoned (dried) before burning. Seasoning reduces the moisture content, which minimizes smoke and creosote production and improves burning efficiency.

Why Seasoning Matters:

Freshly cut (green) wood can contain up to 50% moisture. Burning green wood results in:

Excessive Smoke: Water needs to be evaporated before the wood can burn efficiently, leading to a smoky fire.
Low Heat Output: Energy is wasted evaporating water instead of producing heat.
Increased Creosote: Incomplete combustion due to high moisture content leads to more creosote buildup.

How to Season Cedar:

Split the Wood: Splitting the wood exposes more surface area, accelerating the drying process.
Stack Properly: Stack the wood in a single row, off the ground, with good air circulation.
Location: Choose a sunny, windy location for optimal drying.
Time: Cedar typically needs 6-12 months of seasoning, depending on the climate and the size of the splits.

How to Tell if Cedar is Seasoned:

Weight: Seasoned wood will be significantly lighter than green wood.
Cracks: Look for cracks on the ends of the wood.
Sound: When you bang two pieces of seasoned wood together, they will sound hollow.
Moisture Meter: A moisture meter is the most accurate way to determine moisture content. Aim for a moisture content below 20%.

My Experience: I once rushed the seasoning process with a batch of cedar, and the results were disastrous. The fire was smoky, it barely produced any heat, and I had to clean my chimney much sooner than expected.

Expert Tip #2: Mix Cedar with Hardwoods – A Balanced Approach

Burning cedar exclusively isn’t ideal due to its high creosote production and fast burn rate. A better approach is to mix cedar with hardwoods like oak, maple, or ash.

Why Mix Woods?

Reduce Creosote: Hardwoods burn cleaner and produce less creosote than cedar.
Increase Heat Output: Hardwoods provide more sustained heat.
Extend Burn Time: Hardwoods burn slower than cedar.

How to Mix:

Start with Cedar Kindling: Use small pieces of cedar to get the fire going quickly.
Add Hardwood Logs: Once the cedar kindling is burning well, add larger hardwood logs for sustained heat.
Maintain a Balance: Aim for a mix of approximately 25% cedar and 75% hardwood. This will give you the benefits of cedar (easy ignition, pleasant aroma) without the drawbacks (high creosote, fast burn rate).

Data Point: According to the Chimney Safety Institute of America (CSIA), mixing wood types can significantly reduce creosote buildup. They recommend using seasoned hardwoods as the primary fuel source and limiting the use of softwoods like cedar.

Expert Tip #3: Mind Your Fireplace – Maintenance Matters

The type of fireplace you have and its condition will influence how safely and efficiently you can burn cedar.

Fireplace Types:

Open Fireplace: Open fireplaces are the least efficient and produce the most smoke. They also pose the greatest risk of sparks escaping. Burning cedar in an open fireplace requires extra caution.
Fireplace Insert: Fireplace inserts are more efficient than open fireplaces and provide better heat control. They also reduce the risk of sparks escaping.
Wood Stove: Wood stoves are the most efficient wood-burning appliances. They provide excellent heat control and minimize smoke and creosote production.

Maintenance:

Annual Chimney Inspection: Have your chimney inspected annually by a qualified chimney sweep. They can identify potential problems and remove creosote buildup. The average cost of a chimney sweep is $150-$300, but can vary based on location and the complexity of the job.
Chimney Cleaning: Clean your chimney regularly, especially if you burn cedar frequently. The frequency of cleaning will depend on how often you use your fireplace and the type of wood you burn. The CSIA recommends cleaning your chimney when there is 1/8 inch of creosote buildup.
Damper Operation: Ensure your damper is functioning properly. A properly functioning damper will help regulate airflow and prevent smoke from entering your home.
Spark Arrestor: Install a spark arrestor on your chimney to prevent sparks from escaping.

Personal Story: I once neglected to clean my chimney for too long, and I ended up with a chimney fire. Thankfully, the fire department was able to put it out quickly, but it was a scary experience. It was a costly lesson in the importance of regular chimney maintenance.

Expert Tip #4: Burn Hot Fires – Promote Complete Combustion

Burning hot fires promotes complete combustion, which reduces smoke and creosote production.

How to Burn Hot Fires:

Use Seasoned Wood: Seasoned wood burns hotter and cleaner than green wood.
Provide Adequate Airflow: Ensure your fire receives enough air. Open the damper fully and adjust the air vents as needed.
Don’t Smother the Fire: Avoid overloading the fireplace with wood. This will restrict airflow and lead to a smoky fire.
Top-Down Burning: Consider using the top-down burning method. This involves placing larger logs at the bottom of the fire and smaller kindling on top. This method promotes cleaner and more efficient burning.

The Science Behind It: Complete combustion occurs when there is enough oxygen and heat to burn the fuel completely. Incomplete combustion occurs when there is a lack of oxygen or heat, resulting in the production of smoke, creosote, and other pollutants.

Data Point: Studies have shown that burning hot fires can reduce creosote production by up to 50%.

Expert Tip #5: Safe Handling and Storage – Protect Yourself and Your Investment

Proper handling and storage of cedar firewood are essential for safety and preserving its quality.

Handling:

Wear Gloves: Wear gloves when handling firewood to protect your hands from splinters and dirt.
Lift Properly: Lift firewood with your legs, not your back, to prevent injury.
Avoid Overloading: Don’t try to carry too much firewood at once.
Be Aware of Insects: Check firewood for insects before bringing it indoors. Some insects, such as termites and carpenter ants, can damage your home.

Storage:

Elevated Storage: Store firewood off the ground to prevent moisture absorption and insect infestation.
Covered Storage: Cover firewood with a tarp or store it in a shed to protect it from rain and snow.
Good Air Circulation: Ensure good air circulation around the firewood pile to promote drying and prevent mold growth.
Distance from House: Store firewood away from your house to reduce the risk of insect infestation and fire hazards. A minimum of 20 feet is generally recommended.

Cost Considerations:

Purchasing Firewood: The cost of firewood varies depending on location, wood type, and quantity. A cord of seasoned hardwood can range from $200 to $400 or more. Cedar is often sold at a lower price point, but the cost per BTU (British Thermal Unit) may be higher due to its lower density.
Cutting Your Own Firewood: If you have access to cedar trees, you can cut your own firewood. However, this requires an investment in tools, such as a chainsaw, splitting axe, and safety equipment. You also need to factor in the cost of fuel and maintenance for your equipment.
Chainsaw Costs: A decent homeowner-grade chainsaw can range from $200 to $500. Professional-grade chainsaws can cost $800 or more.
Splitting Axe Costs: A good quality splitting axe can cost $50 to $100.
Safety Equipment Costs: Safety equipment, such as a helmet, safety glasses, and gloves, can cost $50 to $100.
Permits: In some areas, you may need a permit to cut firewood on public land. The cost of a permit can vary depending on the location.
Labor: If you hire someone to cut and split firewood for you, you’ll need to factor in the cost of labor. Labor costs can vary depending on the location and the experience of the worker. I’ve seen rates range from $25 to $50 per hour for firewood processing.

Budgeting for Firewood:

Estimate Your Needs: Determine how much firewood you will need for the winter. A typical homeowner may use 2-4 cords of firewood per year.
Compare Prices: Shop around and compare prices from different firewood suppliers.
Consider DIY Options: If you’re willing to put in the work, cutting your own firewood can save you money.
Factor in Storage Costs: If you don’t have a suitable place to store firewood, you may need to invest in a shed or tarp.
Account for Maintenance: Don’t forget to factor in the cost of maintaining your fireplace and chimney.

Case Study: My Firewood Project Budget

Last year, I decided to cut and split my own firewood. Here’s a breakdown of my costs:

Chainsaw Rental: $50 (I didn’t want to purchase a new chainsaw for this project)
Fuel and Oil: $20
Safety Equipment (Gloves and Glasses): $30 (I already had a helmet)
Permit: $25 (Required for cutting on state land)
Time Investment: Approximately 20 hours

I ended up with about 1 cord of mixed hardwoods and cedar. While the initial cash outlay was relatively low, the time investment was significant. If I had paid someone to do the work, it would have cost me around $300.
