If you're burning wood to heat your home or run your business, not all firewood is equal. At The Logsmith, we supply ultra kiln dried logs with moisture content below 15 percent. That makes them hotter, cleaner, and more cost-effective than standard kiln dried logs, which typically sit between 15 and 18 percent moisture.
This isn’t just a small detail — it makes a big difference to how your fire burns, how much wood you use, and how clean your air stays. Our firewood is used by homes and businesses across the UK — from woodburners and open fires to BBQs, pizza ovens, hot tubs and saunas.
Why moisture content matters
Ultra kiln dried logs contain more energy. Hardwood logs with 7 to 15 percent moisture content deliver between 4,700 and 5,000 kilowatt-hours (kWh) per tonne. Logs with 15 to 18 percent moisture typically deliver 4,400 to 4,700 kWh per tonne. That’s a difference of up to 10 percent in energy output, based on figures from HETAS and the Forestry Commission.
What this means is simple: the drier the log, the more heat you get per burn. That’s better performance from every fire — whether you’re heating a home, running a commercial stove, or cooking over open flame.
Use fewer logs over the season
To generate 15,000 kWh of heat over a typical UK winter, for standard 15 to 18 percent moisture kiln dried logs, you'd need 3.4 tonnes. Whereas, for our ultra kiln dried logs with less than 15 percent moisture, you would only need around 3.1 tonnes. That’s around 10 percent less wood to get the same warmth — based on energy conversion estimates from Defra’s Ready to Burn scheme and HETAS combustion performance data.
Less wood means fewer deliveries, less storage space, and less hassle. You burn less and spend less — without compromising on comfort.
Cleaner fires, cleaner air
Logs with lower moisture content create a stronger flame with less steam, which improves combustion and reduces soot and tar build-up inside your stove or flue. This helps your appliance run more efficiently, lowers maintenance needs, and supports better indoor air quality.
For homeowners, it means fewer call-outs, cleaner glass doors, and more reliable heat on cold days. For businesses like spas, hotels or off-grid accommodations, that means fewer chimney cleans, better guest comfort, and safer long-term stove use.
Perfect for homes and businesses
We supply ultra kiln dried logs for all types of fire-based heating and cooking. That includes woodburners, open fires, chimineas, wood stoves, pizza ovens, BBQs, fire pits, wood fired hot tubs and outdoor saunas. Whether you're heating a rural home or fuelling a commercial venue, you need reliable firewood that performs.
What about cost?
While ultra kiln dried firewood can cost slightly more per cubic metre — typically between £140 and £160 — you burn 10 to 15 percent less wood across the season. Standard kiln dried logs, priced around £120 to £140 per m³, may seem cheaper up front, but you’ll go through more to achieve the same result.
In most cases, seasonal heating costs come out nearly identical. For example, heating with ultra kiln dried logs over a full winter might cost around £480, compared to £468 using standard kiln dried logs. This is based on average use of a 5kW stove for three hours per day between October and March. The key difference: your ultra dry logs burn hotter, cleaner, and more consistently.
