Must You Cover Firewood to Season Perfectly?
Seasoning firewood is a crucial process that improves its burn efficiency and reduces the smoke and creosote it produces. But as a wood burner, you might be wondering, 'Do I need to cover firewood to season?' The short answer is: it depends. In this comprehensive guide, we'll delve into the intricacies of seasoning firewood and explore whether covering it is necessary.
Seasoning is essentially drying out the firewood by exposing it to the elements, which helps to reduce its moisture content. Freshly cut wood usually has a moisture content of 45-60%, but for optimal burning, this should be reduced to around 20%. This drying process can take anywhere from six months to a year, depending on the species of wood and your climate.
The Benefits of Covering Firewood
While sun and wind are the best natural dryers, covering firewood has its advantages. It can protect the wood from excessive rain, snow, or heat, preserving its quality and preventing mold or decay. So, in areas with harsh weather conditions, covering firewood can indeed be beneficial.
Covering can also help maintain the wood's bark, which can otherwise peel off due to sun and wind exposure. The bark plays a protective role, preventing the inner wood from absorbing moisture.
When and How to Cover Firewood
If you decide to cover your firewood, it's crucial to do so correctly. A proper covering should allow for plenty of air circulation, preventing the wood from staying damp. Here's how to do it:
Use a tarp or a shelter that allows ventilation. Waterproof tarps are suitable for preventing rain, but they can trap moisture, causing the wood to rot. It's best to use a tarp that allows some airflow or a shelter with openings. Additionally, ensure the wood is off the ground to prevent moisture from seeping up.
When Not to Cover Firewood
In some cases, covering firewood may not be necessary or even beneficial. If you live in a dry, sunny climate, the sun can dry the wood effectively. Moreover, excessive covering can trap heat and humidity, which can accelerate decay or attract pests.
Also, covering firewood doesn't speed up the drying process. Even under the best conditions, seasoning takes time, and excessive covering might only impede this natural process.
The Importance of Stacking Firewood Correctly
Regardless of whether you choose to cover your firewood, correct stacking is essential for adequate seasoning. Properly stacked wood allows for air to flow freely around each piece, facilitating the drying process.
Here's how to stack firewood correctly:
- Keep wood off the ground to prevent moisture from being absorbed.
- Stack in rows, with each row slightly shorter than the one before it, to create a 'stair-step' effect that allows for better air circulation.
- Avoid over-stacking, as this can trap heat and moisture, hindering the drying process.
Monitoring the Moisture Content
Regardless of whether you decide to cover or uncover your firewood, it's essential to monitor its moisture content. This can be done using a moisture meter, which is a simple, inexpensive tool that provides an accurate reading of the wood's moisture level.
Once the moisture content is below 20%, your firewood is ready for use. However, if the moisture content is still high, you might need to rethink your seasoning strategy, adjusting the covering or stacking accordingly.
The decision to cover firewood is not a one-size-fits-all answer. It depends largely on your climate and wood species. But regardless of whether you choose to cover your firewood or not, remember that seasoning is a critical process that ensures you have efficient, clean, and safe fires.
