Is Sycamore Good Firewood? Pros, Cons & Expert Tips

If you’ve ever glanced at the towering, leafy sycamore trees scattered throughout the countryside, you might have wondered if they’re suitable for your fireplace or log burner. With many households across the UK looking to maximise warmth efficiently, sycamore’s suitability as firewood is an important consideration. So, let’s answer the burning question: Is sycamore good firewood?

Sycamore Wood Characteristics

Sycamore trees (Acer pseudoplatanus) are abundant across the UK, making sycamore logs readily available and often affordable. This deciduous tree, recognisable by its broad, maple-like leaves, produces wood that splits easily, dries relatively quickly, and burns with a moderate amount of heat.

Heat Output and Efficiency

One of the key factors in choosing firewood is the amount of heat it generates. Sycamore offers a moderate heat output, typically around 19 million BTUs per cord (British Thermal Units). While this might not compete directly with hardwoods like oak or ash, sycamore is certainly effective at keeping your home warm, particularly in transitional seasons like spring and autumn.

Burning Qualities and Smoke Production

Sycamore is known for burning relatively cleanly, provided the logs are properly seasoned. Seasoned sycamore firewood, with moisture content below 20%, ensures efficient combustion and minimal smoke. However, burning unseasoned or “green” sycamore can lead to excessive smoke and soot build-up in your chimney or flue.

Seasoning Sycamore Firewood

Proper seasoning is crucial for getting the best from sycamore. Sycamore typically requires between 9 and 12 months to fully season, making it a faster-drying wood compared to oak or beech. To season your sycamore effectively:

Cut logs into manageable sizes to increase airflow.
Stack in a dry, sheltered location off the ground.
Cover the top, but ensure the sides remain open for ventilation.

Well-seasoned sycamore logs will feel noticeably lighter, show cracks at the ends, and emit a hollow sound when knocked together.

Pros and Cons of Sycamore Firewood

Pros:

Widely available across the UK.
Splits and seasons quickly.
Burns cleanly when properly seasoned.
Affordable compared to other hardwoods.

Cons:

Moderate heat output—less intense compared to denser hardwoods like oak.
Can rot easily if not properly stored.
Produces significant smoke when burned unseasoned.

Best Uses for Sycamore Firewood

Given its characteristics, sycamore is excellent for:

Starting fires: Its ease of ignition makes it an ideal starter wood.
Mixed fuel use: Blend sycamore logs with harder woods to balance burning efficiency and heat output.
Transitional heating: Perfect for mild autumn and spring days when intense heat isn’t required.

Environmental Considerations

Choosing locally sourced sycamore firewood supports sustainable forestry practices and reduces carbon footprints. Sycamore trees regenerate quickly and grow in abundance throughout the UK, making them an eco-friendly firewood choice.

The Verdict: Is Sycamore Good Firewood?

Yes—sycamore is indeed good firewood. While it doesn’t top the heat charts, it scores highly in accessibility, seasoning speed, and environmental friendliness. For optimal results, ensure your sycamore logs are well-seasoned and combine them with denser hardwoods during colder spells.

Ultimately, sycamore is a reliable, practical choice for keeping your home cosy throughout the UK’s colder months.
