Can I use treated wood in a wood burning stove?
As a well - established supplier of wood burning stoves, including Outdoor Firewood Stove, Wood Burning Stove, and Fire Wood Camping Tent Stove, I often receive inquiries from our customers regarding the types of wood they can use in our stoves. One of the most common questions is whether it's safe to use treated wood. In this blog post, I'll delve into the topic to provide a comprehensive answer.
What is Treated Wood?
Treated wood is lumber that has undergone a chemical treatment process to enhance its durability, resistance to decay, insects, and fungi. There are several types of treatments available, including pressure - treated wood, which involves forcing chemicals deep into the wood fibers under high pressure. The most common chemicals used in pressure - treating wood are chromated copper arsenate (CCA), alkaline copper quaternary (ACQ), and copper azole (CA).
In the past, CCA was widely used, but due to concerns about the potential health risks associated with arsenic exposure, its use in residential applications was phased out in 2003 in the United States. Nowadays, ACQ and CA are more commonly used as they are considered to be safer alternatives.
Why Using Treated Wood in a Wood Burning Stove is a Bad Idea
Health Risks
When treated wood is burned, the chemicals used in the treatment process are released into the air in the form of toxic fumes and particulate matter. For example, if the wood was previously treated with CCA, burning it can release arsenic, a known carcinogen. Inhaling these fumes can lead to a variety of health problems, including respiratory issues, skin irritation, and in severe cases, long - term health risks such as cancer.
Even with the newer treatment chemicals like ACQ and CA, burning them can release copper, which can cause irritation to the eyes, nose, and throat. Prolonged exposure to copper fumes can also have more serious effects on the respiratory and digestive systems.


Stove Damage
The chemicals in treated wood can also cause significant damage to your wood burning stove. When the treated wood burns, the chemicals can react with the metal components of the stove, leading to corrosion. Over time, this corrosion can weaken the stove's structure, reducing its efficiency and lifespan. It can also cause blockages in the flue, which can lead to poor ventilation and an increased risk of carbon monoxide poisoning.
Environmental Impact
Burning treated wood is also harmful to the environment. The toxic chemicals released during the combustion process can contaminate the air, soil, and water. These pollutants can have a negative impact on wildlife, plants, and human health in the surrounding area. Additionally, the production of treated wood often involves the use of large amounts of energy and chemicals, which contributes to environmental degradation.
Safe Alternatives to Treated Wood
Seasoned Hardwood
Seasoned hardwood is the best option for use in a wood burning stove. Hardwoods such as oak, maple, and hickory burn slowly and produce a high amount of heat. They also burn more cleanly than softwoods, producing less creosote, which is a flammable substance that can build up in the chimney and cause chimney fires.
To ensure that the hardwood is properly seasoned, it should be stored in a dry, well - ventilated area for at least six months to a year. This allows the moisture content of the wood to drop to around 20% or less, which is ideal for efficient and clean burning.
Kiln - Dried Wood
Kiln - dried wood is another excellent alternative. Kiln drying is a process where the wood is dried in a controlled environment at high temperatures, which quickly reduces the moisture content of the wood. This results in wood that burns more efficiently and cleanly than air - dried wood. Kiln - dried wood also produces less smoke and creosote, making it a safer option for your wood burning stove.
Conclusion
In summary, using treated wood in a wood burning stove is a dangerous and ill - advised practice. The health risks, stove damage, and environmental impact far outweigh any potential benefits. As a responsible supplier, I strongly recommend that you use only seasoned hardwood or kiln - dried wood in your wood burning stove.
