Using the wrong firewood can result in excess smoke, poor heat output, creosote buildup, and even dangerous chimney fires. Below, we break down the best and worst types of wood to burn — and why choosing the right firewood is so important for your safety and comfort.
The best wood for burning is seasoned, dry hardwood. These woods burn longer, cleaner, and produce more heat with less smoke.
Oak is one of the most popular firewood choices. It burns slowly and produces steady, high heat. However, it must be properly seasoned — usually 12 to 24 months — for best performance.
Maple burns cleanly and gives off good heat. It’s easy to split and seasons relatively quickly, making it a reliable option for indoor fireplaces.
Birch burns hot and bright, making it a good starter wood. Because it burns quickly, it’s often best when mixed with slower-burning hardwoods like oak.
Ash has a low moisture content even when freshly cut, so it burns better than most woods even if it’s not fully seasoned. It produces a consistent flame and steady heat output.
Hickory is one of the hottest-burning hardwoods. It produces excellent coals and long-lasting heat, though it requires a longer seasoning time.
Not all wood is safe or efficient to burn. Some produce excess smoke, release harmful toxins, or lead to rapid creosote buildup in your chimney.
Freshly cut wood contains a high moisture content. Burning it produces excessive smoke and contributes to creosote buildup, which increases the risk of chimney fires.
Softwoods burn quickly and contain high amounts of resin and sap. These can coat your chimney with creosote much faster than hardwoods. They may be used for kindling but should not be the main fuel source indoors.
Lumber that has been painted, stained, or pressure-treated should never be burned. It releases toxic chemicals and heavy metals into the air that are harmful when inhaled.
These manufactured wood products are made with adhesives and resins that emit toxic fumes when burned. They also create more ash and burn unevenly.
While it may seem like a convenient option, driftwood often contains salt, which can corrode your chimney and release toxic chlorine gases when burned.
Burning the wrong type of wood affects much more than just fire quality. It can have serious consequences for your health, home, and heating efficiency.
Wet or resinous wood creates creosote — a highly flammable substance that builds up in your chimney.
Treated wood releases dangerous fumes that can cause respiratory issues and indoor air pollution.
Properly seasoned hardwood burns hotter and longer, reducing the amount of wood you need and providing better overall warmth.
Poor firewood leads to colder fires, more smoke, and less comfort.
Using low-quality firewood can lead to frequent chimney cleanings and costly repairs.
Burning the right wood extends the life of your fireplace and reduces long-term maintenance.
Burn only seasoned hardwood, dried for at least 6 to 12 months.
Store firewood in a covered, ventilated area to keep it dry.
Use a moisture meter to ensure your wood has less than 20% moisture content.
Have your chimney professionally cleaned and inspected once a year by a certified company.
