Buy Ash firewood online

Buy ash firewood online: why are kiln-dried ash logs the best firewood for your stove?

Kiln-dried ash logs are the best firewood for UK stoves because ash hardwood burns hot, long, and clean at under 20% moisture. When you want to buy ash firewood online in Britain or anywhere in Europe, ash is the benchmark against which every other hardwood is measured. We have supplied wood fuels since our incorporation in 2009 under company registration number 06928341, and season after season, ash is the species our customers reorder first.

Ask any seasoned stove owner in Cambridgeshire what sits in their log store, and the answer is nearly always the same. Ash lights without coaxing, throws a steady flame and holds its heat through the coldest hours of the night. As one firewood specialist puts it, ash has “stood the test of time, often being labelled the best burning wood of all time and the ‘king of firewood'” (Certainly Wood).

What is kiln-dried ash firewood?

Kiln-dried ash firewood is ash hardwood dried in a kiln to below 20% moisture, so it burns immediately. The process matters because freshly cut ash can hold half of its weight in water. In a kiln, logs are force-dried in controlled chambers, which strips moisture out in days rather than the two years air seasoning can demand (UK Logs Direct). The result is a log that catches fast, burns at high temperature and produces markedly less smoke than wet wood.

Why does the 20% moisture rule matter in the UK?

Since the Air Quality (Domestic Solid Fuels and Smoke Control Areas) Regulations 2020 came into force in England, firewood sold in volumes under two cubic metres must be certified as having a moisture content of 20% or less (Surefirewood). Burning wet wood wastes heat on evaporating water inside the log, and each kilogram of water in the wood consumes roughly 2.44 MJ of energy that should be warming your room (Stalmark). Dry ash gives you that heat instead.

“In England, if wood fuel is sold in quantities of less than 2 cubic metres, it must be certified as Ready to Burn, confirming it has a moisture content of 20% or less.” (Surefirewood)

Which firewood gives the most heat: ash, oak or birch?

Ash gives more usable heat per log than birch and rivals oak, while lighting is far easier than oak. Oven-dry wood of every species holds a net calorific value within a narrow band of 18.5 to 19 MJ per kilogram, according to the FAO’s Wood Fuels Handbook. The difference is density. Hardwoods such as ash, oak and beech pack more mass per cubic metre than softwoods, so you need up to half the volume for the same heat output (Certainly Wood).

How much kiln-dried ash firewood do you need for winter?

A typical UK home heats mainly with a stove, burning roughly 3 to 4 cubic metres of kiln-dried logs per winter. Your true figure depends on stove efficiency, insulation and how many evenings you light it. A stove running at around 70% efficiency needs approximately 0.35 kg of 20% moisture firewood to release 1 kWh of heat, based on a net calorific value of about 4.06 kWh per kilogram (Stack Exchange). Buy by the tonne or truckload, and the price per kWh falls sharply, which is why our commercial customers pre-order early.

Where can you buy ash firewood in bulk in the UK and Europe?

You can buy ash firewood in bulk directly from us by the tonne or full truck, delivered across the UK and Europe. We are Cambridgeshire Straw Pellets Limited, incorporated in 2009, and bulk supply is our trade. Alongside kiln-dried ash logs, we ship wood briquettes, wood pellets, charcoal, sawdust, wood shavings and wood chips for retail, agriculture and industry. Read our story on the about page or place a wholesale order through the shop.

How to store your ash logs after delivery?

Keep your delivery under cover, off the ground and ventilated on all four sides. Even kiln-dried logs will reabsorb surface moisture if stacked against a damp wall. A slatted log store facing away from prevailing wind preserves that sub-20% moisture guarantee right through to spring.

Key takeaways

• Ash is the king of firewood: high heat, easy lighting, minimal spitting.
• Under 20% moisture is both law and efficiency: certified dry logs burn cleaner and hotter.
• Bulk buying wins on price: tonnes and truckloads cut your cost per kWh.
• We are the bulk supplier: incorporated in 2009, shipping across the UK and Europe.

Is ash good firewood for burning?

Yes. Kiln-dried ash burns hot and steady, lights easily, and produces minimal smoke and spitting, which is why UK stove owners call it the king of firewood.

What moisture content should ash logs have?

Ash logs should have a moisture content of 20% or less. UK regulations require this for firewood sold in volumes under two cubic metres in England.

How long do kiln-dried ash logs burn?

A single kiln-dried ash log typically burns for around one hour in a standard stove, longer when banked down with oak for overnight heat.

Can I burn ash logs in a smoke control area?

Yes, if your stove is DEFRA exempt and your logs are certified dry. Kiln-dried ash at under 20% moisture meets the fuel standard for smoke control areas.

How should I order ash firewood in bulk?

Contact us with your tonnage or truckload requirement, and we will quote, schedule, and deliver ash logs to your site across the UK and Europe.
