Why does wood need to be dried
The fungus needs to have moisture in order to survive. So eliminating the moisture will kill any fungus that may already be present and will prevent fungal attacks in the future as long as the wood remains dry. Properly drying the wood also kills any insects and eggs that may be in the wood.
What happens to wood when it dries
Wood initially dries from the shell (surface), shrinking the shell and putting the core under compression. When this shell is at a low moisture content it will 'set' and resist shrinkage. The core of the wood is still at a higher moisture content. This core will then begin to dry and shrink.
What happens if wood is not dried
If wood isn't properly dried, you run the risk of it shrinking or warping, and your project won't be a reflection of the hard work you've put in. Here's what you need to know about proper air drying, kiln drying, and moisture content etiquette.
Why must wet wood first be dried before it can burn
Burning wet wood is a waste of fuel. Because of its high moisture content, extra energy is required to turn the excess water into steam, using up to 30 percent of the heat you are trying to create in the first place. At the same time, it cools the combustible gases—those gases must be hot to burn and create more heat.
What happens if you leave wood wet
Wood is a porous material. This means that, over time, exposure to water will permeate the wood's membranes, causing it to rot, soften, and fall apart. Additionally, water compromises the structure of wood, leading to mold growth and expensive restoration efforts.
How long does wood have to dry before burning
Firewood should be left to dry for a minimum of 12-18 months before being used. To dry wet logs, split logs into smaller pieces and leave logs into a suitable wood store to accelerate drying process.
Can you burn wood that isn’t dry
Wood burned inside the home should always be dry and seasoned for at least 6-12 months. Wood burns most efficiently when the moisture content is at 20% or less. Damp wood burns at a cooler temperature, resulting in incomplete combustion, more smoke, and dangerous creosote build-up in the chimney (a fire hazard).
What happens if you burn wood that isn’t dry
You should never burn green wood. Also known as unseasoned or 'wet' wood, this timber, regardless of species, is counterproductive for burning, and will result in excess smoking and a build-up of creosote (damaging sticky tar deposits) inside of the appliance and flue.
How long should wood dry before burning

Does wet wood not burn
Building a fire from wet wood, also called green wood, is less efficient and less safe than using properly dried or “seasoned” firewood. Firewood should have 20 percent moisture or less. Burning wet wood is less efficient than burning dry wood because so much energy is lost in warming water to steam.
How do you dry logs quickly
Cut it to Size – Cut your logs down to the size you'll want in your fire. Split the logs. The more exposed wood, the faster it'll dry out. Let the Air Flow – When stacking wood, make sure there's plenty of airflow around every log.
Can you wood burn wet wood
Wet firewood is wood that is too high in moisture content to burn efficiently in a fireplace or stove. Wood that is too wet to burn can struggle to catch fire, produce more smoke, release less heat and create an overall unpleasant burning experience.
Does it matter if logs get wet
Each log will have a moisture content of under 20%, to ensure a perfect burn every time. Many people choose to keep their logs outside, so they will inevitably get slightly wet, even if they are kept in a log store. This is totally fine, and won't affect the burning performance of your logs.
What happens if logs get wet
Wet wood is much harder to light, emits more smoke, and doesn't burn anywhere near as brightly as dry wood. It's also much worse for the environment, so it's really important to keep your wood dry throughout the year. Alternatively, you can buy ultra-dry firewood as and when you need it, as we explain below.

How long do logs need to dry before burning
12-18 months
Firewood should be left to dry for a minimum of 12-18 months before being used. To dry wet logs, split logs into smaller pieces and leave logs into a suitable wood store to accelerate drying process. Make sure the top of wood store is covered to keep moisture out.
How dry should logs be before burning
20%
Green or freshly felled logs are not suitable for burning in a domestic stove or open fire until they have been dried to 20% moisture content or less.
How long do logs need to dry

How do you know if wood is too wet to burn
If the ends of the wood pieces are moist, and don't have cracks or checking, that is a sure sign of green or damp wood. A smoldering fire is another sign you are burning wet wood.
Can you burn wood that’s been rained on
'Even well seasoned firewood can be ruined by bad storage. Exposed to constant rain or covered in snow, wood will reabsorb large amounts of water, making it unfit to burn and causing it to rot before it can be used. '
How do you dry logs out fast
To speed the drying of firewood, remove the bark initially and stack the wood so that air circulates around it from all sides. During rainy periods, put a cover over the top of firewood.

Seasoning or Air-Drying Wood: The One-Year Rule
In fact, expect most types of wood to take about one year per inch of thickness to dry out. If it's a two-inch log, that means you'll need to let it sit outdoors for two whole years before it's dry enough to efficiently burn.
How long do logs have to dry
It can take 3-12 months or longer to season firewood. On average, it usually takes around 6-months to dry out the cut-firewood that you purchased from a store or supplier. Depending on the original timber's moisture content, it can take more or less time to season.
What happens to logs when they get wet
Many people choose to keep their logs outside, so they will inevitably get slightly wet, even if they are kept in a log store. This is totally fine, and won't affect the burning performance of your logs. In fact, the wind outside will help keep them dry, as it will wick away excess moisture.
