Flammability Testing: Are There Any Quick At-Home Tests For Firewood?

Firewood Moisture Content Test

To determine if your firewood is dry enough for safe burning, you’ll need a firewood thermometer or a simple water drop test. The ideal moisture content for firewood is between 15% and 20%. If the moisture content is higher than 20%, it may produce less heat, produce more creosote, and be more prone to mold and rot. You can use a firewood thermometer to check the moisture content by inserting the probe into the wood. The thermometer will display the temperature of the wood, and you can use a chart to convert the temperature to moisture content.

Water Drop Test

If you don’t have a firewood thermometer, you can use the water drop test to check the flammability of your firewood. This test involves dropping a small amount of water onto a piece of firewood. If the water beads up and rolls off the wood, it’s likely dry enough to burn. However, if the water absorbs quickly into the wood, it may be too damp to burn safely.

Preparing Firewood for Rainy Conditions

When it’s raining, it’s essential to choose firewood that’s specifically designed to burn in wet conditions. Look for firewood with a moisture content of 25% or less, as it will burn more efficiently and produce more heat. Additionally, you can try to dry out your firewood by storing it in a covered area, such as a gazebo or a covered patio. This will help to reduce the moisture content and make it easier to burn.
