Once you have settled on the right species of wood for your log burner, the next decision is how it has been dried. Both kiln-dried and seasoned logs can meet the Ready to Burn standard and perform brilliantly, but they get there in very different ways, and each suits slightly different households. Here is how they compare, so you can choose with confidence.
What Are Kiln Dried Logs?
Kiln-dried logs are dried in a controlled, heated kiln over a matter of days rather than months. This process reduces moisture content quickly and consistently, typically bringing logs down to around 10 to 15%, comfortably below the 20% Ready to Burn threshold. Because the process is controlled, every batch tends to perform in a very predictable way, with minimal variation between deliveries.
Kiln-dried logs are ready to burn as soon as they arrive, with little need for further drying time or specialist storage.
What Are Seasoned Logs?
Seasoned logs are dried naturally, cut and split, then left to air dry outdoors under cover for anywhere between six months and two years, depending on the species. Denser hardwoods like oak take considerably longer to season than a species like ash or birch.
Provided seasoned logs have been stored correctly, kept off the ground, covered from rain and allowed good airflow, they can reach the same 20% moisture threshold as kiln-dried wood and burn just as cleanly. The result depends heavily on how well the seasoning process has been managed.
Kiln Dried vs Seasoned: How They Compare
| Factor | Kiln Dried Logs | Seasoned Logs |
|---|---|---|
| Typical moisture content | Very consistent, often 10 to 15% | Variable, aiming for 20% or below with correct storage |
| Time to ready | Ready to burn immediately on delivery | Requires months of drying time before use, unless bought pre-seasoned |
| Consistency between batches | Highly consistent due to controlled process | Can vary depending on species, storage and how long it has seasoned |
| Storage needs once delivered | Minimal, though covered storage is still recommended | Needs continued dry, ventilated storage to maintain moisture level |
| Typical cost | Slightly higher, reflecting the drying process | Often more cost effective, particularly when bought in advance |
Both options, when sourced from a reputable supplier who tests moisture content, will give you a clean, efficient burn. The right choice often comes down to convenience and how much storage space you have at home.
Which Should You Choose?
If you want a ready-to-burn product with no waiting and minimal storage requirements, kiln-dried logs are the more convenient option, particularly useful if you are ordering as you go through the season.
If you have suitable storage space and prefer to plan ahead, buying seasoned logs in advance, ideally over spring or summer for the following winter, can be a cost-effective way to build up a reliable supply. Just make sure you have somewhere dry, covered and well-ventilated to keep them in good condition.
Many of our customers use a mix of both, keeping a smaller stock of kiln-dried logs on hand for convenience while working through a larger seasoned supply bought earlier in the year.
Do Both Meet the Ready to Burn Standard?
Both drying methods can produce wood at 20% moisture content or below. Ready to Burn certification is separate from the drying method: look for the certification mark when buying logs for immediate use. Every batch of logs we supply, whether kiln-dried or seasoned, is tested for moisture content before it reaches you. See our log supply page for the hardwood options available.

How to Store Whichever You Choose
Even kiln-dried logs will slowly reabsorb moisture if left exposed to the elements, so a covered, well-ventilated log store is worth having whichever type you order. Stack logs off the ground, allow air to circulate, and keep them under cover but not sealed in, since trapped moisture can be just as much of a problem as rain.
As a general guide, order only as much seasoned wood as your storage space can properly protect. A smaller, well-kept stock burns better than a larger pile left exposed to damp.

Kiln Dried vs Seasoned Logs FAQs
Is kiln dried firewood better than seasoned firewood?
Neither is strictly better, they simply suit different needs. Kiln-dried logs offer consistency and are ready to burn immediately, while properly seasoned logs, given enough time and correct storage, perform just as well and are often more cost effective.
How much more expensive is kiln dried wood compared to seasoned?
Kiln-dried logs typically cost a little more, reflecting the energy and time involved in the drying process. Seasoned logs, particularly when bought in advance, tend to offer better value for larger quantities.
Can I mix kiln dried and seasoned logs in the same fire?
Yes, there is no issue burning both together, provided both meet the Ready to Burn moisture standard. Many households do this as a matter of course.
How long do seasoned logs stay usable once delivered?
Properly stored, kept dry and off the ground with good airflow, seasoned logs can be kept for a long time without losing quality. Poor storage, however, can allow them to reabsorb moisture within weeks.
Do kiln dried logs need to be stored undercover?
Yes, while they arrive very dry, kiln-dried logs will slowly reabsorb moisture if left exposed to rain or damp ground, so covered storage is still recommended even for short periods.
Which burns hotter, kiln dried or seasoned wood?
Heat output depends more on wood species and moisture content than on the drying method itself. A kiln-dried and a well-seasoned log of the same species, both meeting the 20% moisture threshold, will burn with very similar heat output.
