Kiln dried logs are recommended by stove manufacturers, stove fitters, sweeps and most fans of wood burning stoves and fires. So what exactly is the big deal? Read on to find out…
Our kiln dried logs have a moisture content around 8-12%. They will light more easily, burn consistently and cause little or no soot or deposits on your stove glass or chimney. Kiln dried logs burn hotter than less well seasoned alternatives. In addition, we exclusively use Beech and Ash which you will find produce more BTU’s* per weight than other species.
Ideally a log for burning should be no higher than 20% moisture content. This is achievable by air drying in the right conditions but takes skill and time. Ash may take 18 months but Oak as long as 3-4 years!
Traditional methods of preparing seasoned logs can give you a very acceptable product but because it takes years to air-dry timber in this manner, you may find ‘seasoned firewood’ on sale isn’t what it seems. Testing with a moisture meter is the only accurate way to find out how much water is still inside the log.
Beware that badly seasoned logs sold by the tonne may mean a substantial part of what you are buying is water (inside the logs) not heat producing timber.
Kiln Dried = more efficient
Why do they produce more heat? Simple. The seasoning process removes water. A fresh cut log may contain 50% water or more. For each 1 kilogram log, that would mean half a litre of water. This means much of the energy contained in the log would be used to evaporate the water, not to heat your room.
Badly seasoned logs leave you with less heat and may mean you are paying for water not logs.
Kiln drying is a convenient and reliable process. Our logs are dry-stored afterwards so they stay in top condition until they leave our yard.
The Kiln is fuelled with offcuts from the yard. This makes us more efficient economically and environmentally and provides a waste free process.
We can give you advice on how to best store your logs. Ford Logs also build solid, long lasting log stores for optimum storage. We design to suit your taste and advise the best place to locate your log store for best air-flow and protection. Contact us for more information.
