Fuel and Storage

Our Ready to Burn logs which are dried below 20% moisture provide you with the ultimate burn quality with maximum heat output. The kiln drying process in our wood fired kilns remove most of the water for you, down to below an average of 20% moisture content which ensures your stove glass is kept clean. The lack of moisture in the logs will also prevent a build-up of soot or tar in your chimney or flue and because you get so much heat output, you will actually need less logs, than if you were to buy seasoned logs, thus providing you with great value for money. You can also expect a consistent product that you can rely on every time, unlike ‘seasoned logs’ which can be inconsistent in terms of their moisture content due to the natural and varied drying process. The standard length of 25cm kiln dried logs is recommended by stove manufacturers to fit 99% of wood burning or multi-fuel stoves, but you can choose from larger 35cm and 50cm logs if your wood burner is large enough. If you want very large logs, you can also choose our chunky logs which are much larger in diameter.

What are kiln dried logs?

This is firewood that has been force-dried in kilns in a short space of time rather than dried naturally or more commonly known as ‘seasoning’ over a period of time. The aim is to get the logs to below 20% moisture content which is what they need to be for the optimum burn. We only process timber which has been sourced from sustainably managed woodlands which means we only take thinnings which are required for healthy woodlands.

The time taken to dry logs in kilns can vary depending on the drying system used, but typically it will take about 7-10 days in a chamber which runs at around 60 – 70 °C. At Certainly Wood, we have a unique drying system which runs at much higher temperatures with fans to circulate the hot air. Our kilns can dry wood in approx. 50-hour cycles and each time, we put 18 tonnes into a kiln and take 12 tonnes out – therefore removing 6 tonnes (6,000 litres) of water!
