The answer is, yes. Timber that is too dry can ignite and burn quickly and aggressively, using large volumes of air, which in turn can increase particulate emissions. It’s about getting the balance right. A small percentage of water is actually beneficial for wood burning, between 12 – 20%.
Is burning dry wood bad?
These emissions can contribute to poor local air quality. It’s therefore always recommended to only burn properly seasoned or kiln dried firewood, where the moisture content of the wood is at an acceptable level that will lead to a clean burn of the wood with significantly reduced harmful emissions.
Is it better to burn dry wood?
Research shows that firewood that is dried to below 20% moisture content will not only provide the most efficient burn but also provides the most heat output, ensuring your stove and chimney or flue have minimal soot, avoiding any tar build-up.
Why should you only burn dry wood?
But the truth is that burning wet firewood is a false economy and will cost you more in the long term. Instead, we recommend only burning kiln dried firewood for the following reasons: Greater heat output than wet wood. Greatly reduced emissions and improved air quality compared to burning wet wood (see graph below)
How long should wood dry before burning?
It’s a year-round task because firewood requires anywhere from six months to two years dry out. Late winter and early spring are ideal times to cut and store wood for the following year. It allows wood to dry over the summer months, seasoning in time for colder weather.
Can logs be too dry?
It’s not something that most people complain about very often, but yes, wood can be too dry and burn faster than would be the case at an optimal 10-15% MC.
Is it illegal to burn wet wood?
The new rules will only apply to the sale, distributing and marketing of wet wood – and it will not be illegal to own or burn wet wood after the cut-off date, whether from your garden or a shop. Burning wet wood and coal in homes emits huge amounts of minuscule pollutants, known as PM2.
Does dried wood burn longer?
Kiln dried wood can catch fire and burn much more quickly compared to seasoned firewood due to its generally lower moisture content.
How do you get moisture out of wood?
Place a dehumidifier in the center of the room once all of the standing water is removed. Set it to the highest extraction setting possible. Turn it on and leave it running for at least 24 hours to pull moisture from the boards. Place fans blowing across the surface to further aid in drying the wood out.
