Understanding Firewood Moisture Content and Its Impact on Storage

Understanding Firewood Moisture Content and Its Impact on Storage

Do you want to use your firewood more efficiently without struggling? Well, for this you must understand moisture content while organizing them. Moisture content in firewood refers to the amount of water present in the wood. 

This factor significantly impacts how well the firewood burns, its heat output, and how you should store it. Let’s find out why moisture content matters and how to manage it effectively.

What is Firewood Moisture Content?

Firewood moisture content is the percentage of water in the wood compared to its dry weight. Freshly cut wood, also known as green wood has up to 50% water or more. As the wood dries, the moisture content decreases. For firewood to burn efficiently, its moisture content should ideally be below 20%.

Why Moisture Content is Crucial?

1. Burning Efficiency

Wet wood doesn’t burn well. It produces more smoke and less heat because the fire has to first evaporate the water before burning the wood. This can lead to a smoky fire that doesn’t provide much warmth. 

Dry wood burns hotter and cleaner. It produces less smoke, creates a steady flame, and provides more heat. You also get teary and irritated during this process.

2. Environmental Impact

Burning wet wood releases more pollutants into the air. The smoke contains creosote, a sticky substance that can build up in your chimney and cause dangerous fires. You also have to clean your chimneys or areas where you burn your firewood more frequently. Dry wood burns cleaner and is better for the environment and your chimney. 

3. Storage Considerations

Greenwood or wet wood can attract insects and mold. It can also rot if not stored properly. Properly dried and stored wood has a low chance of mold or insects. It’s easier to handle and burns more efficiently.

How to Measure Firewood Moisture Content?

You can measure firewood moisture content using a Woodhaven moisture meter. This handheld device gives a quick reading of the moisture level. Simply split a piece of wood, stick the probes into the freshly exposed wood, and read the meter. Aim for a reading below 20% for optimal burning.

Tips for Proper Firewood Storage

1. Seasoning Your Wood

What is Seasoning?

Seasoning means allowing the wood to dry out before using it. This process can take six months to a year, depending on the type of wood and the conditions.

How to Season Wood

Split the wood into smaller pieces, stack it in a way that allows air circulation, and keep it off the ground. Cover the top to protect it from rain but leave the sides open for air flow.

2. Stacking Techniques

Choose a sunny, well-ventilated area for stacking your firewood. Stack the wood in a crisscross pattern to allow air to circulate. Use a strong firewood rack to properly store the firewood. Keep the stack about a few inches off the ground using pallets or a rack to prevent moisture from the soil.

3. Covering Your Wood

Use a tarp or a purpose-built firewood cover to protect the wood from rain and snow. Make sure to cover just the top of the stack, leaving the sides open to allow moisture to escape.

Note: Use proper tools such as a firewood cart, log carrier, and thermal lined gloves while stocking the firewood.

Common Mistakes to Avoid

  • Stacking Too Tightly: If wood is stacked too tightly, air can’t circulate, and the wood won’t dry properly. Always leave space between pieces for airflow.

  • Storing Wood Indoors Immediately: Don’t bring wood indoors until it’s properly seasoned. Wet wood can increase indoor humidity and attract pests.

  • Ignoring Moisture Content: Always check the moisture content before burning. Even if the wood looks dry, it might still contain too much moisture.
  • Conclusion

    Understanding and managing firewood moisture content is essential for efficient and safe burning. Properly seasoned wood burns better and helps protect the environment and your home. 

    Knowing the moisture content and the right way to store these woods correctly makes sure your firewood is ready to provide warmth and comfort whenever you need it. Visit our website (Firewood Racks) to explore more products and accessories required for firewood storage.
