When you want to get the most out of your firewood and fireplace or stove, you should always use dry firewood. Dry wood provides you with the best combustion. Burning dry firewood also helps in avoiding particle emissions. The moisture content in well-seasoned firewood is lower than 18%. Moisture content is the amount of water present in the wood. Moisture content 20% means 1 kg of wood contains 200 grams of water.

When you are buying firewood from wood suppliers, don’t forget measuring the moisture content. It should not be more than 20%. As the water content is low, your logs produce the maximum heat. As compared to the moist firewood, the efficiency of dry firewood is much higher. When you are using moist firewood to burn, it produces less heat and more smoke. So, you are not only causing damage to the environment, you might also end up causing discomfort to your neighbours.
Is Your Firewood Dry?
There are several methods you can use to check if your firewood is well-seasoned or not.
- You can use washing-up liquid to test your firewood.
- You can also use the sound test. Bang two logs together. If you notice a hollow sound, your firewood is well-dried for burning.
- Look for fungi, mould and dirt. These are the signs of moisture.
- You can also use a wood moisture meter.
Using the Soap Test
In this method, all you need is your regular washing soap to test the dryness of the wood.
- Take a log and add soap on one of its ends.
- Blow through the log from the other end.
If you can see bubbles, it is dry firewood. There are some channels transporting water. When the wood is dry, the water disappears and air passes easily.
Using The Sound Test
This is the easiest test as all you need is two logs. Just bang them together. Dry firewood produces hollow, hard and ringing sound. On the other hand, moist firewood produces a dull sound. There are some pitfalls you cannot ignore when you are using the sound test. In frosty weather with temperature below 0° Celsius, striking fresh firewood logs also produce a high and ringing sound. So, you need to season your firewood.
Looking At The Firewood
You can also rely on your intuition to ensure if your logs are properly seasoned or not. The following checklist can help you in assessing the moisture content of the log.
- The firewood must look dry.
- It must be clean.
- The must be hard and have dry cracks on both ends.
- There must be no sign of fungi or mould.
- There must be no smell of juice and resin.
- Growth rings must be clearly visible.
- The log must be light in colour.
- The bark should be separated from the wood.
Using A Wood Moisture Meter
A wood moisture meter is a device used to measure the moisture content of the firewood. This test is the most reliable test as the meter provides you with the most precise information.
Seasoned firewood is always ready to keep your family warm and cozy. You can also buy fresh firewood and season it at home.
