Not all fireplaces are built the same — and the type of firewood you burn plays a major role in safety, efficiency, and the lifespan of your system. At Chimney Champions, one of the most common issues we see is damage caused by improper burning practices.
Whether you have a traditional masonry fireplace or a prefabricated (factory-built) fireplace, choosing the right wood makes all the difference.
Masonry (Brick) Fireplaces
Masonry fireplaces are built from brick and mortar and are designed to handle high heat. While they are durable, they still require the correct fuel to perform properly.
Best Wood Choices:
Seasoned hardwoods such as:
Oak
Hickory
Maple
Ash
These hardwoods should be dried (seasoned) for 6–12 months before burning. Properly seasoned wood:
Burns longer and more consistently
Produces more heat
Creates less smoke
Reduces creosote buildup
Burning unseasoned (green) wood creates excessive smoke and moisture, which leads to creosote accumulation inside your chimney — a leading cause of chimney fires.
Prefabricated (Factory-Built) Fireplaces
Prefabricated fireplaces are engineered systems made primarily of metal and designed to operate within specific temperature limits. While they can safely burn seasoned hardwood, they are more sensitive to overfiring than masonry fireplaces.
Important Considerations:
Use well-seasoned hardwood only
Burn moderate-sized splits
Avoid overloading the firebox
Follow the manufacturer’s guidelines
Because these systems are tested and rated for controlled burns, excessively large fires or improper wood can:
Warp metal components
Crack panels
Damage the chimney system
Overfiring is one of the most common causes of premature failure in prefab fireplaces — and often results in costly repairs or full replacement.
What You Should Never Burn
No matter what type of fireplace you have, certain materials should never go into your firebox:
Treated or pressure-treated wood
Painted or stained lumber
Construction scraps
Trash or cardboard with inks
Plywood or particleboard
These materials:
Release toxic chemicals
Produce excessive soot
Dramatically increase creosote buildup
Can damage your chimney liner and fireplace components
Why Proper Wood Selection Matters
Using the correct firewood:
Reduces creosote buildup
Improves heating efficiency
Minimizes smoke issues
Protects fireplace components
Helps prevent chimney fires
According to the National Fire Protection Association, failure to clean chimneys and improper burning practices are leading factors in home heating fires. Burning properly seasoned hardwood is one of the simplest ways to reduce that risk.
