Certainly Wood has produced kiln dried firewood in Herefordshire since 2006. Kiln drying takes moisture out of hardwood far more reliably than air drying, so every log burns the same way from the first bag to the last. Drier wood gives you more heat per log, less smoke and less tar building up in your flue. If you're weighing up the options, read our guide to kiln dried vs seasoned logs.

Pick the format that suits your storage and how often you burn:

  • Log crates: hand-stacked ash, oak, birch or mixed hardwood that doubles as a log store.
  • Small bags and boot bags: easy to carry, good for top-ups or tricky access.
  • Bulk bags: loose-filled mixed hardwood in 25cm or 35cm lengths, our most popular option.
  • Logs in boxes: compact packs for small stoves and limited space.

Why are kiln dried logs better than seasoned logs?

Kiln dried logs are better than seasoned logs because they have a lower and more consistent moisture content. This allows kiln dried logs to burn hotter, produce less smoke, and provide more reliable performance. Seasoned logs can vary in moisture, making them less predictable to use.

What are the best kiln dried logs for a wood burner?

The best kiln dried logs for a wood burner are hardwood logs that are dried below 20% moisture and cut to the correct size for your stove. Hardwoods like ash provide long, steady heat, while birch offers quicker ignition and bright flames. Mixed hardwood options can balance ease of lighting with longer burn time. Choosing the right kiln dried logs for a wood burner improves efficiency, heat output, and overall performance.

What are the best kiln dried logs for a log burner?

The best kiln dried logs for a wood burner are logs that are consistent in size, easy to handle, and dried to below 20% moisture. Logs around 25cm in length suit most UK stoves and allow good airflow for efficient burning. Choosing kiln dried logs with a mix of diameters helps create a strong fire base and maintain heat over time.

What is the most cost-effective way of buying kiln dried logs?

The most cost-effective way of purchasing logs is to buy in larger volumes, such as an extra-large crate. The Extra-Large Crate offers the best value per cubic metre, making it the most cost-effective option across the range. Each crate is neatly stacked to maximise volume, meaning you receive more usable wood with no wasted space. This makes it ideal for regular use or stocking up for winter.

How much firewood will I need for a typical winter?

The amount of firewood you need for a typical winter depends on factors such as your stove efficiency, property size, insulation, and how often you use your stove. However, for an average household using kiln dried logs, you will typically need around 3–4 cubic metres of firewood over winter.

Using dry, kiln dried logs is important, as wetter wood can require up to twice as much to produce the same heat. Our extra-large crates are a great bulk option for keeping stocked up over winter.
