The best place to dry firewood is outside. The bounty of natural conditions such as sunlight and air movement aid in the efficient drying of the cut firewood. Make the most of these free resources by choosing an open, sunny spot.
• Stacking Firewood
To maximize exposure to the sun and breeze, it is advisable to stack firewood in a single row off the ground. This layout ensures maximum ventilation, promoting a swifter drying process. If unable to elevate the stack directly, consider laying it on a detached wooden surface like pallets.
• Firewood Covering
While the common belief may prompt you to cover drying firewood, it’s usually best to leave it uncovered. However, a makeshift roofing structure, perhaps from some roofing iron, could shield the firewood from rain or snow without stiferring airflow.
• Indicators of Dry Firewood
There are several visual and tactile pointers to identify dry firewood. Firstly, dry firewood feels much lighter than when it was freshly cut. Secondly, the wood often appears bleached, indicating prolonged exposure to sun and air. Thirdly, the grain at the ends of the firewood develops cracks.
• Handheld Assessment
By assessing the feeling of the cut ends, it’s possible to differentiate between dry and freshly cut wood. Dry ends will feel warm, giving a dry sensation, whereas freshly cut ends are likely to be cold and damp.
• Auditory Indicators of Dry Firewood
There’s an audible test to check the dryness of firewood. When two pieces of dry wood are thumped together, they will produce a ringing, hollow sound. In contrast, wet wood makes a muffled, dull thud.
• Heating Evidence
An excellent way to test your firewood’s net dryness is by throwing a small piece into a glowing hot fire. Wet wood tends to sizzle due to evaporating water content. On the other hand, dry wood will ignite within one minute.
The Saga of Hardwoods and Softwoods
• The Realm of Hardwoods
Hardwood trees produce covered seeds and generally take a longer time to season around 18 months in most cases. This longer duration results in firewood that burns for an extended period.
• Softwoods Swift and Efficient
Softwoods are evergreen trees that produce uncovered seeds, and these types generally dry faster, usually within 6-12 months. This type of wood is useful for rapidly heating a fire. However, they burn faster and, consequently, require twice the amount of hardwood to generate the same heat.
