FAQs

  • Is moldy firewood safe to burn?

    Surface mold on firewood is safe to burn, though it indicates excessive moisture. Brush it off before burning and improve storage to prevent recurrence.

  • What size should firewood pieces be?

    Firewood should typically be 16 inches long and split to 4-6 inch diameter. Measure your fireplace or stove to confirm the right size before ordering.

  • What firewood produces the best coals?

    Oak and hickory produce the best, longest-lasting coals. Black locust also excels where available, while ash provides good coals with easier processing.

  • What is kiln-dried firewood?

    Kiln-dried firewood is dried in heated chambers to 10-15% moisture in days, burning hotter and cleaner than air-seasoned wood.

  • Can you burn firewood in the rain?

    You can burn well-seasoned firewood during rain if it’s been stored under cover. Focus on dry kindling and sheltered fire pits for outdoor burning in wet weather.

Splitting firewood serves essential purposes beyond fitting pieces into your fireplace or stove. The splitting process dramatically accelerates drying, exposes interior wood to air and heat, creates manageable sizes for handling and burning, and ultimately determines how effectively your wood performs as fuel.

Moisture removal is the primary reason for splitting. Water escapes wood much more quickly through end grain and split surfaces than through bark. A whole log with bark intact can take years to season, while that same log split into pieces dries in months. The more surface area exposed, the faster moisture evaporates. This is why smaller split pieces season faster than large ones.

Split wood ignites and burns far more efficiently than rounds. Whole logs are difficult to light because fire can’t easily penetrate to the interior. The outer bark layer resists ignition and insulates the wood inside. Split pieces present exposed wood directly to flames, allowing fire to spread quickly. The irregular shapes of split wood also create air gaps when stacked in a firebox, promoting better combustion.

Size management matters for practical burning. Most fireplaces and wood stoves require pieces no more than 16-18 inches long and 4-6 inches in diameter. Trying to burn whole logs or oversized pieces leads to incomplete combustion, excessive smoke, and inefficient heat production. Properly sized split wood burns completely and generates maximum heat.

The ideal split size depends on your heating appliance. Smaller pieces (2-4 inches) work well for kindling and starting fires. Medium splits (4-6 inches) serve as primary fuel for most applications. Larger pieces (6-8 inches) can be used for overnight burns in large wood stoves but may be too big for standard fireplaces.

Wood splits most easily when freshly cut (green) rather than after partial seasoning. The moisture actually lubricates the grain, making splitting easier. Dry wood becomes harder and often requires more force. This is why most firewood processing involves splitting soon after cutting, then allowing the split pieces to season.
