Burn Time and Flame Quality
Rapid Ignition: Like most softwoods, larch catches fire effortlessly far quicker than dense hardwoods. This makes it a practical choice for getting a fire established without needing an mountain of kindling.
Robust, Steady Flames: Larch produces a strong, consistent flame with excellent visual appeal. Unlike the rapid, flickering burn of spruce, it maintains a steady combustion that provides much more reliable warmth.
Extended Burn Duration: A standout advantage is its longevity; larch typically burns 50–70% longer than spruce. While a spruce log might vanish in 45 minutes, a larch log can sustain heat for up to 100 minutes.
Reduced Reloading: For busy households, larch is far more convenient. It extends the intervals between reloading to nearly two hours, compared to the constant attention required when burning lighter softwoods.
Resin Content, Smoke, and Sparks
A Balanced Resin Profile: Larch contains natural resins but is far more refined than pine. It offers a cleaner burn with less sparking while retaining effortless ignition, making it a practical, less temperamental fuel for modern homes.
Safety for Open Hearths: While suitable for open fires, larch requires caution. Its resin pockets can pop, making a sturdy fire screen a non-negotiable requirement. It provides a bright, lively flame but should never be left unattended.
Excellence in Modern Stoves: Enclosed burners are the ideal environment for larch, safely containing sparks while regulating airflow for a clean burn. It is an outstanding choice for contemporary stoves, delivering high-intensity heat that rivals hardwoods once seasoned below 20%.

Pros and Cons of Larch Firewood
Examining both advantages and limitations helps determine whether larch suits your specific heating requirements and budget.
Advantages of Larch Firewood
Higher heat output for a softwood: The standout benefit—it delivers 20-30% more heat than spruce or pine per log. When comparing superior performance to other softwoods, heat output provides the clearest answer: yes.
Burns hotter and longer than spruce or pine: This dual advantage makes larch substantially more efficient. You get more heat per log and need to reload less frequently, directly addressing the primary limitations of typical softwoods. For those asking is larch a good firewood for sustained heating, these characteristics provide strong affirmative evidence.
Widely available in the UK: UK forestry includes substantial larch plantations, particularly in Scotland and Wales. This availability means it can often be sourced locally, supporting regional forestry while minimizing transport emissions and costs.
Faster seasoning than hardwoods: Larch seasons in 6-12 months compared to 18-24 months for oak or beech. This quicker turnaround makes it more practical for those unable to plan years ahead or maintain large seasoning stockpiles.
Good value for money: Priced between basic softwoods and premium hardwoods, larch offers excellent performance-to-cost ratio. When evaluating value, the combination of reasonable pricing with strong performance makes it attractive for budget-conscious households wanting better heating than spruce provides.
Disadvantages of Larch Firewood
Still burns faster than hardwood: Despite longer burn times than spruce, larch doesn't match oak or beech for sustained burning. Hardwood logs lasting 3-4 hours exceed larch's 90-120 minute typical burn time. So is larch good firewood for overnight burns? Not ideally, hardwoods remain superior for that application.
Resin can contribute to creosote if burned wet: Like all softwoods, unseasoned larch produces problematic creosote deposits in chimneys. This larch firewood review emphasizes that proper seasoning below 20% moisture is essential—wet larch negates its advantages while creating chimney hazards.
Not ideal as sole fuel for overnight burns: For those asking whether it's suitable for banking fires overnight, the honest answer is it's not the best choice. While you can maintain fires with larch, hardwoods like oak provide more reliable overnight burning with less frequent attention.

Is Larch Firewood Suitable for Wood Burners and Open Fires?
Many people wonder whether larch suits modern heating appliances—suitability depends on your specific setup and usage patterns.
Wood-Burning Stoves
Very suitable when well-seasoned: Modern wood-burning stoves handle properly dried larch (under 20% moisture) excellently. So is larch a good firewood for stoves? Absolutely, it's one of the best softwood choices available.
Produces strong heat output: Larch delivers substantial warmth suitable for primary heating in well-insulated homes. The heat output rivaling lighter hardwoods makes it practical for sustained heating during cold weather.
Performs well mixed with hardwood or alone: Unlike basic softwoods best reserved for kindling, larch works effectively as main fuel. You can burn pure larch loads or mix with hardwoods, using it to establish heat quickly, then adding hardwood logs for extended burns. This versatility is a key advantage noted in this larch firewood review.
Open Fires
Can be used with caution: While larch is a capable fuel for open hearths, it demands a degree of caution. Because it is prone to spitting and sparking as the resins heat up, it should only be used in an open fire if a sturdy spark guard is kept firmly in place. With the right safety measures, however, it provides a wonderfully bright and cheerful fire.
Some sparking possible: Resin content means larch can produce occasional sparks in open fires. While less dramatic than pine, sparking still occurs, making protective measures advisable.
Spark guard recommended: Always use fire screens when burning larch in open fireplaces. This simple precaution prevents embers from escaping the fireplace area, making it safe for open fire use.
How to Season and Store Larch Firewood
Proper preparation is crucial for achieving the performance described in this larch firewood review and ensuring safe, efficient burning.
Seasoning Time
Typically 6-12 months: Larch seasons faster than dense hardwoods but slower than low-density spruce due to its medium-high density. Cut and split in spring, larch should reach burnable moisture levels by autumn or winter.
Much faster than oak or beech: Compared to 18-24 months for premium hardwoods, larch's 6-12 month seasoning represents significant advantage. This quicker preparation makes it more accessible for those unable to maintain multi-year stockpiles.
Moisture Content Guidelines
Target below 20%: UK "Ready to Burn" certification requires firewood under 20% moisture content. Well-seasoned larch should achieve 15-20% moisture when properly dried. This moisture level is essential for the performance this review describes.
Why wet larch increases creosote risk: Using 'green' larch with a moisture content above 25% is a significant risk, as it leads to heavy smoke and dangerous creosote build-up. The wood's reputation for high performance depends entirely on proper seasoning; burning it wet not only kills the heat output but also creates a genuine chimney fire hazard
Testing moisture content: Use a moisture meter on freshly split log faces (not ends, which dry faster). Test multiple logs from different stack areas to ensure consistency before burning. This verification confirms your larch firewood has reached safe, efficient burning moisture levels.
Storage Best Practices
Stack off the ground: Elevate larch on pallets, racks, or blocks preventing ground moisture wicking into bottom logs. Even 10-15cm clearance significantly improves drying and prevents rot that compromises wood quality.
Cover top only: Use waterproof covering (tarp, corrugated roofing) over the top protecting from direct rainfall, but leave sides completely open allowing airflow. Fully wrapping in plastic traps moisture and condensation, preventing proper seasoning.
Allow airflow on sides: Proper ventilation is critical for seasoning larch. Open sides allow moisture to escape while preventing mold growth that occurs in sealed storage. Good airflow accelerates drying and maintains wood quality.
Rotate older logs forward: Practice first-in, first-out inventory management. Move older, better-seasoned larch to accessible positions while placing newly split logs at the back of storage. This ensures you burn properly seasoned wood while newer logs continue drying.
Best Ways to Use Larch as Firewood
Strategic use maximizes the advantages identified in this larch firewood review, ensuring you get optimal performance and value from your fuel.
As main fuel for short to medium burns: Larch works excellently as primary fuel for 2-4 hour fires. Its combination of easy ignition, good heat output, and decent burn time makes it ideal for evening heating or daytime supplemental warmth without the extended commitment of slow-burning hardwood.
Mixed with hardwood for extended fires: For the most efficient heating, many UK homeowners use a 'hybrid' approach. Start your fire with larch to generate a quick, intense heat that brings the room up to temperature rapidly, then transition to hardwoods for sustained, overnight warmth. This strategy perfectly balances larch’s effortless ignition with the long-lasting endurance of denser logs
Ideal for autumn and winter evenings: During colder months when you need substantial heat but not overnight burns, larch provides ideal performance. The strong heat output warms spaces effectively while 90-120 minute burn times suit typical evening use patterns perfectly.
Excellent alternative when hardwood is expensive: When hardwood prices spike or availability drops, larch offers an excellent fallback option. Performance approaching lighter hardwoods at lower cost makes it economically attractive.
This review confirms that larch is the gold standard of softwoods for UK homes. Its superior density and heat output elevate it from mere kindling to a legitimate primary fuel. While it won't outlast premium hardwoods overnight, its performance-to-cost ratio is unbeatable, making it the most efficient and affordable conifer for modern wood burners.
