Reading firewood right

  1. Split a test piece.
  2. Push the pins into the fresh inside face, along the grain.
  3. Read several pieces from the stack.
  4. Burn when they read under 20 percent (EPA).

The outside of a log dries first, so a reading on the bark side flatters wet wood. EPA's other signs of seasoned wood: darker, lighter in weight, hollow sound when two pieces knock. Missouri's conservation department adds that bark pulls off dry firewood by hand. Guide: how to season firewood.

Frequently asked questions

What moisture content should firewood be?

Below 20 percent, per EPA's Burn Wise guidance. Test the fresh inner face of a split piece, not the bark side.

How do you test firewood with a moisture meter?

Split a piece and push the pins into the fresh inner face; the outside reads drier than the core.

Pin or pinless meter for firewood?

Pin meters read deeper into split wood; pinless meters scan surfaces without holes and suit lumber and walls.

How long does firewood take to get under 20 percent?

EPA says season at least six months; dense hardwoods often take longer, so measure.

Can a moisture meter check lumber too?

Yes; Clemson Extension notes air-dried lumber dries toward the local equilibrium moisture content.
