What is the moisture content of seasoned wood?
The ideal moisture content for seasoned firewood is 20% – 25%.
What happens when you burn firewood?
When firewood is cut, it leaches out a lot of water. That fresh-cut wood has an average moisture content (MC) of anywhere from 50 to 90 percent – and that’s too wet for ideal burning conditions. If you burn green or unseasoned firewood in your fireplace or woodstove, the log will not combust efficiently, and there may be smoke coming out your chimney as well as creosote buildup which poses a serious risk to both you and your home’s safety.
How to tell if firewood is too much bark?
Another method can be done by weighing it with a cheap hydrometer that you can find at your local store for around $20-30 dollars. One more way would be pulling off one end and slowly seeing how many small chips come out before they start leaving large chunks behind (which means there’s too much bark on them).
What woods burn well?
Very dense hardwoods (ash, beech) with less than 14% moisture will burn well and last for a while; this is what most seasoned firewood experts prefer to use when building their flame source!
How to know if a log is good for burning?
First of all, look for how much bark is left on the logs when choosing which ones will work best for burning later on. If it looks like almost every bit of surface area was stripped off during processing then it might have been stored outside long enough for moisture content to take its toll. In other words, don’t buy from that supplier again they have changed their quality over time.
Can you use wet wood as fuel?
Wet wood can still be used for fuel. However, it will not burn as efficiently and also creates a lot of smoke when burned. Fortunately, there is an easy way to dry out the wet firewood – by using heat from your fireplace or woodstove!

What percentage of firewood should be dry?
The moisture content of seasoned firewood should be between and 20 percent. The ideal amount is around 20%. Trying to cut it down any lower than that will mean your logs are bound to burn very slowly, meaning they won’t heat up the way you want them to.
How to tell if firewood is too wet?
The most noticeable sign that your firewood is too wet or unseasoned is when you try to light it on fire. If there's no smoke coming from underneath the logs as they burn, this means that they're either not dry enough yet (less than 20% moisture content) or aren't properly seasoned (more than 25%). Also keep in mind even though many people think this way, splitting the wood will not dry it out. This is a myth!
How to keep firewood from rotting?
Make sure your firewood is properly stacked and protected from rot and bugs, as these will ruin the wood over time if they’re not kept at bay during storage or drying periods. It’s also important that you stack it in an open space where air can circulate around them for maximum efficiency.
What is the best wood to burn?
Seasoned hardwoods burn better than softwoods like pine because they contain more energy. This post is about how to tell the difference in wood types when it comes to differentiating their burning abilities and which ones are best suited for cooking fires, campfires, or outdoor grilling areas. By knowing all these facts you will find that not only will your wood last longer but also produce a very hot flame great for cooking over! It takes time and patience to cut down trees (one can never hurry nature), saw them into logs using an axe/chainsaw, split the logs with either an ax or maul, stack them properly so air can circulate and allow them to season, and then get the firewood ready for use.
How long does seasoned wood dry?
Seasoned firewood is wood that has been left to dry for at least six months. It contains more energy than freshly cut logs, but not as much as green (freshly cut) wood. The moisture content of seasoned firewood should be between 20% and 40%.
Why is seasoned wood considered green?
The reason being that when seasoned hardwoods get below this level they are considered ‘seasoned’ which means less smoke during combustion and better flame quality while reducing creosote buildup inside flues and chimneys. Therefore if a supplier tells you he has seasoned firewood at 30% or above then be careful because these types of woods are typically considered ‘green’ and are much harder to light.
How much moisture is needed to season firewood?

Why is my firewood not seasoned?
Firewood typically won’t be able to reach these low moisture content levels through seasoning because of the moisture in the air. You can expect you logs to be fully seasoned by the time they have reached below 20% moisture content.
How much moisture does wood burn?
The Environmental Protection Agency states that firewood burns its most efficiently at 15% – 20% moisture content. Within this moisture content range, the amount of water in the wood is low enough for a fire to burn the wood without any major issues, while also being high enough so that the wood doesn’t burn too quickly.
What is the best moisture level for firewood?
Try to get your moisture level down below the 20 percent range for easier fires. That’s the point where firewood gets easy to light and puts off much less smoke. Generally speaking, the fires will burn much better than they did with wet wood.
How to measure moisture content in wood?
Remove the end cap of your moisture to reveal the pins (only applies to a pinned meter). With the cover removed the pins will be used to measure the moisture content. The device will send an electromagnetic charge through the wood to determine the resistance level.
Why does firewood give off so little heat?
How much heat was it giving off? Wet firewood gives off very little heat since so much of the energy is used to get rid of excess moisture. That’s why it seems like smaller logs give off way more heat. It’s because smaller pieces of wood dry faster than larger logs in the same pile. You can use smaller pieces of firewood to get the temperature levels up if a good chunk of your firewood is wet.
How to read a wood moisture meter?
With a pinless meter you hold it against the wood, and a pinned meter would be pushed into the wood. Press the start button and it will give you a moisture reading. Some of the more advanced meters make you input the species of wood, but it’s usually choose between hardwood/softwood.

What is a moisture meter?
A moisture meter is a cheap handheld device that can be used to measure the moisture content of wood. It uses an electromagnetic signal to measure the resistance throughout the wood. Water is an excellent conductor so higher resistance means less overall moisture.
How much moisture does a fire burn?
Don’t stop the drying process there! Fires really start to burn once moisture levels drop down into the 10-15 percent range. That’s where you reach the optimal burn range. You will almost zero smoke, fires will burn extremely hot, there will be little ash, and the logs still last a long time.
What is the moisture level of wood?
What are Acceptable Moisture Levels in Wood? The acceptable moisture levels of wood and lumber are in the range of 6% to 8% for interior and 9% to 14% for exterior wood or for building envelope components within constructed assemblies.
Why is it not recommended to use wood with a moisture content above 14%?
Using wood with a moisture content above 14% isn’t recommended because it may have detrimental long-term effects on the construction.
What is a pinless moisture meter?
Pinless Wood Moisture Meters. Pinless meters are non-penetrating and read the moisture content via a non-damaging electromagnetic sensor that scans the wood. Because pinless meters scan the wood’s surface and cover a larger area than pin-type meters, they provide a more thorough picture of the wood’s moisture content.
How is wood tested?
The wood sample being tested is dried in a special oven or kiln and its weight periodically checked. Once the wood sample’s weight stops changing, its weight is compared to what it was before the drying process began. This weight difference is then used to calculate the wood’s original moisture content.
Why is moisture in wood more than water?
Because the moisture content of wood is equal to the weight of the water in the wood divided by the weight of the wood without the water, it’s possible for the moisture content to exceed 100%. In other words, the water weighs more than the wood fibers.
Why is kiln drying used?
Eventually, this internal moisture will evaporate by itself. However, kiln drying is used to speed up the process. Some of the unfinished wood you see on the market has been kiln-dried to reduce its water moisture content to around 8% so that it won’t suffer from moisture-related defects like warping and buckling.
What are the factors that determine the moisture content of wood?
The acceptable moisture content in wood depends on two factors: The wood’s final use. The average RH of the environment where the wood will be used. These two factors make it difficult to say anything specific about acceptable wood moisture content.
How Does Moisture Affect Wood?
Wood is hygroscopic. What does that mean? Moisture influences the strength of the wood. When the moisture content of the wood increases, this expands the wood. As humidity decreases, so does the moisture, shrinking the wood. This is known as EMC, or equilibrium moisture content.
How To Calculate Moisture Content Of Wood
The average moisture content of wood can easily be determined using the dry weight method. You can also use a moisture meter. If you’re using a meter, the resistance should have some hammer electrodes and insulated probes.
Average Moisture Content Of Wood
The standard moisture content of wood stands between 8% and 25% by weight. The EMC of the wood corresponds to the air temperature and the relative moisture.
Moisture Content Of Kiln Dried Wood
Kiln-dried wood usually shows a moisture reading of 10% on the outside and then 25% on the inside. The moisture content overall is almost always below 20%. Logs, siding, shiplap, and T&G must be kiln-dried to stop the wood from shrinking or pulling apart.
Acceptable Moisture Levels In Wood
Moisture levels between 9-14% for anything outdoors. Anything under a 30% moisture level is generally acceptable, depending on the application.
Why Is Wood Moisture Content So Important?
