What You'll Learn
Types of wood suitable for multi-fuel stoves
When considering burning wood in a multi-fuel stove, it’s essential to choose the right type of wood to ensure efficient combustion, minimize emissions, and protect your stove. Not all wood is created equal, and selecting suitable varieties can significantly impact performance. Hardwoods, such as oak, ash, and beech, are among the best choices for multi-fuel stoves. These woods have a high density, which means they burn slower and produce more sustained heat compared to softwoods. Hardwoods also have lower moisture content when properly seasoned, reducing smoke and creosote buildup in the chimney.
Softwoods like pine, spruce, and fir can also be burned in multi-fuel stoves, but they come with certain drawbacks. Softwoods are less dense and burn faster, meaning they require more frequent refueling. Additionally, they contain higher resin content, which can lead to increased soot and tar deposits in the stove and chimney. If you choose to burn softwoods, ensure they are well-seasoned and use them sparingly, ideally mixed with hardwoods to balance the burn rate and reduce maintenance issues.
Seasoned wood is crucial for any type of wood burned in a multi-fuel stove. Seasoning involves drying the wood for at least six months to a year, reducing its moisture content to below 20%. Properly seasoned wood burns hotter, cleaner, and more efficiently, regardless of whether it’s hardwood or softwood. Unseasoned or "green" wood contains high moisture levels, which can lead to inefficient burning, excessive smoke, and potential damage to your stove.
Another suitable option for multi-fuel stoves is kiln-dried wood, which has been dried in a kiln to achieve a moisture content of around 10-15%. Kiln-dried wood burns even more efficiently than seasoned wood and is readily available in many areas. It’s particularly useful if you lack the space or time to season your own wood. However, it is often more expensive than traditionally seasoned wood.
Finally, avoid burning treated or painted wood in a multi-fuel stove, as these materials release toxic chemicals when burned, posing health risks and potentially damaging the stove. Stick to natural, untreated wood varieties to ensure safe and efficient operation. By choosing the right types of wood and ensuring they are properly seasoned or kiln-dried, you can maximize the performance and longevity of your multi-fuel stove while enjoying a warm and cozy fire.

Differences between burning wood and coal in multi-fuel stoves
Multi-fuel stoves are designed to burn a variety of fuels, including wood and coal, but there are distinct differences in how these fuels perform and the considerations required for each. Understanding these differences is essential for efficient and safe operation of your stove.
Fuel Characteristics and Combustion:
Wood and coal have fundamentally different combustion properties. Wood burns faster and at a higher temperature, typically requiring more frequent refueling. It produces a lively, dancing flame that is visually appealing but requires proper airflow to burn efficiently. Coal, on the other hand, burns slower and at a lower temperature, providing a steady, long-lasting heat output. It produces a more consistent, smoldering burn with fewer flames. Coal also requires less frequent refueling but needs a well-insulated firebox to maintain combustion.
Stove Settings and Airflow:
When burning wood in a multi-fuel stove, the riddling grate (if present) should be fully open to allow ash to fall away, ensuring proper airflow beneath the fuel. The air controls should be adjusted to provide ample oxygen for the fast-burning wood. For coal, the riddling grate should be partially or fully closed to retain a bed of hot ash, which helps maintain the lower combustion temperature coal requires. Airflow should be restricted compared to wood to prevent the coal from burning too quickly or inefficiently.
Heat Output and Efficiency:
Wood provides a rapid, intense heat that is ideal for quickly warming a space but may require more frequent tending. Coal delivers a more sustained, even heat, making it suitable for longer periods without refueling. However, coal typically produces more ash and requires a stove with a robust firebox to handle its combustion byproducts. Wood generally burns cleaner and leaves less residue, but it may not provide the same prolonged heat output as coal.
Environmental and Maintenance Considerations:
Burning wood is often considered more environmentally friendly, especially if using sustainably sourced, seasoned logs. It produces fewer harmful emissions compared to coal, which releases more carbon dioxide and particulate matter. However, coal can be more cost-effective in areas where it is readily available. Maintenance-wise, wood stoves require regular ash removal and chimney cleaning to prevent creosote buildup, while coal stoves need attention to ash management and potential soot accumulation due to its denser smoke.
Safety and Fuel Storage:
Wood and coal also differ in storage requirements. Wood should be stored in a dry, well-ventilated area to maintain its moisture content below 20% for efficient burning. Coal, being denser and less prone to moisture absorption, can be stored in bulk but should be kept dry to prevent degradation. Safety-wise, coal burns without open flames, reducing the risk of sparks, but its fumes can be hazardous if proper ventilation is not maintained. Wood, with its open flames, requires careful handling to avoid accidental fires.
In summary, while multi-fuel stoves accommodate both wood and coal, the choice of fuel impacts combustion, heat output, maintenance, and environmental considerations. Understanding these differences ensures optimal performance and longevity of your stove.

Proper wood seasoning and moisture content for efficient burning
Burning wood in a multi-fuel stove is entirely possible and can be highly efficient, but it requires proper wood seasoning and moisture management to ensure optimal performance and minimize environmental impact. Proper wood seasoning is the process of drying wood to reduce its moisture content, which is crucial for efficient combustion. Freshly cut wood, often referred to as "green wood," contains a high moisture content, typically between 30% and 50%. Burning such wood is inefficient because a significant portion of the energy is wasted evaporating water rather than producing heat. Additionally, burning wet wood can lead to creosote buildup in the chimney, increasing the risk of chimney fires.
To achieve proper wood seasoning, wood should be split into logs and stacked in a dry, well-ventilated area, preferably under a cover to protect it from rain. The stacking method is important; logs should be arranged in a way that allows air to circulate freely around them. It is recommended to season wood for at least six months to a year, depending on the type of wood and climate conditions. Hardwoods like oak and maple generally take longer to season than softwoods like pine. A properly seasoned log should have cracks at the ends, a dull appearance, and a moisture content of around 20% or less.
Moisture content is a critical factor in wood burning efficiency. Wood with a moisture content above 20% will not burn as hot or as cleanly as properly seasoned wood. To measure moisture content accurately, use a wood moisture meter, which is an inexpensive and essential tool for anyone burning wood regularly. Ideally, wood should have a moisture content between 15% and 20% for the most efficient and clean burn. Burning wood with lower moisture content ensures a hotter fire, less smoke, and reduced emissions of harmful pollutants like particulate matter.
In addition to seasoning, storing wood correctly is vital to maintaining low moisture content. Even seasoned wood can absorb moisture if stored improperly. Keep wood off the ground by using a raised platform or pallets, and ensure it is covered to protect it from rain and snow. Avoid stacking wood directly against walls, as this can trap moisture. Regularly rotating the stack can also help ensure all pieces dry evenly. Proper storage practices, combined with adequate seasoning time, will guarantee that the wood is ready for efficient burning in a multi-fuel stove.
Finally, when burning wood in a multi-fuel stove, always follow the manufacturer’s guidelines for fuel type and moisture content. Using properly seasoned wood not only enhances the stove’s efficiency but also prolongs its lifespan by reducing the risk of corrosion and creosote buildup. By prioritizing proper wood seasoning and monitoring moisture content, you can enjoy a warmer home, lower fuel costs, and a reduced environmental footprint when burning wood in your multi-fuel stove.
