What Moisture Level Should Firewood Be?

Quick Answer 💧

Firewood should have a moisture content below 20%. This is the UK “Ready to Burn” standard and ensures cleaner burning, higher heat output and safer chimney performance.

Why Moisture Content Matters

Wet logs waste energy drying themselves before producing heat.

This leads to:

• poor stove performance
• excess smoke
• blackened glass
• chimney deposits

Dry logs solve all of these issues.
