Kiln-Dried vs Seasoned Logs: Which Is Better for Your Stove?

As soon as the evenings turn colder, log burners start getting more use. If you are ordering logs for winter, you have probably seen both kiln-dried and seasoned hardwood advertised. One sounds more technical, but does that make it a better choice?

Not necessarily. Both can perform well. What matters most is how dry the wood is when it goes into your stove, how it has been stored and whether it is the right size for your appliance.

What is the difference between kiln-dried and seasoned logs?

Kiln-dried logs are dried using controlled heat in a kiln. The process removes moisture relatively quickly and can offer a consistent result when properly managed.

Seasoned logs are allowed to dry naturally over time, usually after being split and stacked where air can circulate. They may take a year or considerably longer to reach a suitable moisture content, depending on the species, log size and storage conditions.

Neither method guarantees good firewood on its own. Kiln-dried logs can get wet again if stored badly, and properly seasoned hardwood can be just as suitable for burning as kiln-dried wood when it reaches the same moisture level.

The number to check is moisture content

Dry wood burns more efficiently than wet wood. Too much water in a log means part of the fire’s heat is spent evaporating moisture rather than warming your room. Damp wood tends to create more smoke and deposits in the chimney.

Aim for logs with a moisture content of 20% or less, and follow your stove manufacturer’s instructions. A moisture meter can be useful if you want to check a load yourself. For a more representative reading, split a log and test the freshly exposed face, not just the outside.

Even a well-maintained stove burning dry wood produces air pollution, so avoid unnecessary burning and ensure the appliance and flue are used and maintained correctly.

What does ‘Ready to Burn’ actually mean?

In England, firewood sold in volumes of less than two cubic metres must be certified under the Ready to Burn scheme. Certification covers wood fuel with a moisture content of 20% or less, but a supplier simply saying its logs are dry is not the same as being certified. You can check the guidance on GOV.UK.

If you are buying a small load, ask for the Ready to Burn certification details, including the supplier’s certification number. For loads of two cubic metres or more, different seller requirements apply and customers should receive drying and storage advice.

This is especially worth checking when comparing local suppliers. ‘Seasoned’ and ‘kiln-dried’ tell you how the timber was dried, not whether the seller has met every applicable requirement.

Is seasoned hardwood worth buying?

Yes, provided it is suitably dry and properly stored. Seasoned hardwood is a practical choice for many households. Buying locally can also mean the supplier knows where the timber came from, rather than relying on a product with little information about its origin.

Different woods have different burning characteristics. Oak generally takes longer to season and can provide a long-lasting fire. Birch is easier to light but tends to burn faster. A mixed hardwood load can be useful for everyday heating.

Whatever the species, dry logs, the right appliance and good airflow matter more than a promise that one type of timber is automatically best.

How to store firewood through winter

Keep your logs off the ground and protected from rain. An open-sided log store with a roof is often better than a damp, tightly enclosed shed, because the wood needs ventilation. Avoid wrapping the entire stack in plastic with no airflow.

Order before you run out if possible. That gives you time to put your delivery away properly and check its condition. Only bring inside the amount you expect to use in the short term.

Frequently asked questions

Are kiln-dried logs always better than seasoned logs?

No. Both can be good fuel if they are properly dried. Check the moisture content, storage and supplier information rather than relying on the label.

What moisture level should firewood have?

A moisture content of 20% or less is the commonly recommended threshold for logs used in domestic stoves and fires.

Can I burn firewood in a smoke control area?

Rules apply to both the appliance and fuel. If you live in a smoke control area, check that your appliance is exempt for burning wood and follow its conditions and instructions.

Does T. Howie deliver logs to Ripon or Knaresborough?

The log sales service lists both areas among its delivery locations. Contact the team with your postcode to confirm availability and delivery options.
