Logs for wood-burning stoves – What is the best wood?

Hardwood trees, such as Ash, Beech, Birch, Blackthorn, Elm, Eucalyptus, Hawthorn, Hazel, Hornbeam, Maple, Oak, Rowan, Sycamore, Wild Cherry, Willow, Alder, Apple, and Pear, are preferred for stove fuel.

Hardwoods are slow-growing deciduous trees with higher density logs than softwoods, which are evergreen trees such as pines/firs/spruces. Hardwood logs produce up to 50% more heat than softwood logs.

Different types of hardwood have different properties: oak, beech, ash, birch, and elm have the highest heat output, while fruit trees also have a high heat output.

Why wood for stoves & fires should be dry

For best results, wood should be as dry as possible (moisture content of 20% or less). Damp wood uses heat to evaporate the water in the wood, which makes less heat from the fire and more condensation in the chimney.

Types of wood – “Kiln-dried” Wood

Kiln-dried logs are dried in an oven, which removes the majority of the water from the wood, resulting in logs with a moisture content of less than 20%.

Burning kiln dried logs keeps your stove glass clean and prevents soot or tar buildup in your chimney or flue. Furthermore, because kiln-dried wood has a much higher heat output, you will burn fewer logs than seasoned logs, giving you excellent value for money.

Because the energy that would otherwise be released into your living room is instead used to evaporate the water contained in the log, dry wood produces more heat than wet wood. This means that reducing the water content of your log by half nearly doubles the amount of heat it produces.

Certainly Wood is our preferred supplier of kiln-dried wood in our area (opens in a new browser window).

Call into our showroom to purchase bagged kiln dried logs from Certainly Wood.

Wood should be as dry as possible (moisture content 20% or less) for optimal performance; damp wood uses heat to evaporate the water in the wood, producing less heat from the fire and more condensates in the chimney.

The Woodsure Ready to Burn initiative is a Government backed scheme which indicates to consumers that the firewood they are buying is suitable for immediate use i.e. ready to burn.

Types of wood – “Seasoned” Wood

Before burning wood, it must be “seasoned” so that energy is not used to dry it out during combustion. Wet wood produces less heat, but it also causes tar deposits in the chimney.

Outdoors, wood should be “seasoned” for at least 18 to 24 months. Wood should be stored off the ground, with plenty of space between the logs to allow for air circulation and with the top covered to keep rain and snow off the wood.

When banged together, well-seasoned wood produces a distinct ‘clack’ rather than a dull ‘thud.’ Other signs of a seasoned log include bark cracking, peeling, and splitting across the grain of the wood.

Seasoned wood produces approximately 50% more heat than unseasoned wood of the same volume, requiring fewer logs to provide warmth and reducing the number of condensates/tar inside the stove and chimney. Condensates are a major contributor to chimney fires.

We personally advise using kiln-dried wood. Kiln-dried logs are dried to less than 20% moisture content and are suitable for immediate use in all wood-burning appliances. These logs offer a clean burn with maximum heat output.

In our showroom, we sell bagged “Kiln dried” logs as well as a limited supply of very dry (equivalent to “Kiln dried” logs) “Seasoned” wood.

The Forestry Commission offers a free guide to selecting and drying logs (PDF format), which can be downloaded here (opens in a new window), and the Solid Fuel Association offers a guide to wood and multi-fuel wood here (opens in a new window).

When unseasoned logs (Green Wood) or wood with a moisture content greater than 25% are burned, creosote type condensates form in the flue system. These will not only obstruct the chimney flue, but they are also highly flammable, posing a real risk of a fire.
