Autumn’s chill has settled in, and for many households across the UK, that means it’s time to think about how to keep hearths and stoves burning efficiently through the winter. If you use a woodburner, open fireplace or multi-fuel stove, you’ll have come across plenty of choices: seasoned logs, bagged logs, bulk deliveries, local suppliers, and more. But one increasingly popular option—and for good reason—is buying kiln-dried logs delivered in mammoth bags. In this post, I’ll explain what kiln-dried logs are, what benefits mammoth bags provide, and why this combination offers strong advantages over other options.
What Are Kiln-Dried Logs?
Before discussing why you might want them in mammoth bags, let’s clarify what “kiln-dried logs” are and how they differ from other firewood.
- Moisture content matters. Logs freshly cut or only air-seasoned often retain high moisture levels—even up to 35–50 %. That moisture must evaporate when the wood is burning, which uses up heat and reduces efficiency and often leads to excessive smoke. Kiln drying drives out much more of that moisture in a controlled environment, typically bringing logs down to moisture contents around 15–20 % (or lower).
- Cleaner, hotter, more efficient burn. With less moisture to evaporate, kiln-dried logs ignite more easily, burn with a hotter flame, and produce less smoke and creosote. That’s beneficial both for you (higher heat yield) and for your chimney (less creosote buildup).
- More predictable performance. Because kiln drying is a controlled process, the logs tend to have more consistent moisture levels and better burning characteristics. You don’t get “hit or miss” batches that may have been inconsistently seasoned.
- Certification and standards. Reputable suppliers often offer kiln-dried logs that meet recognised industry standards (e.g. Woodsure Ready to Burn scheme, etc.). That assures you of quality, compliance with smoke control zones, and that you’re getting true dry wood—not partly damp logs dressed up as premium stock.
When you combine those benefits with good packaging and delivery, you get a far more convenient and effective heating fuel.
What Is a Mammoth Bag?
“Mammoth bag” is a term used by us at Logs Direct to describe a large, heavy-duty woven sack capable of carrying a large volume of logs. Our Mammoth bags measure 120cm high, 85cm wide and 85cm deep. This gives a volume of approx. 867 Litres, but you often get much more as the weight of the logs when loaded bulges outward. You can rest assured, all our mammoth bags are filled to the brim to give you maximum quantity of logs in the bag.
Here are some characteristics:
- High capacity. A mammoth bag can carry a large quantity of logs in one go, reducing the frequency of deliveries and handling.
- Robust material. These bags are made from heavy-duty woven polypropylene (or similar) that can support substantial weight and resist tearing. These bags can be recycled at specialist recycling points. Read more about recycling your log bags here.
- Ease of handling. Each mammoth bag features lifting loops, making it easier for our delivery lorries to place it near your property (driveway, garden, yard) without requiring many manual transfers.
- Weather/storage protection. Although they are not fully waterproof, mammoth bags offer a degree of protection from dampness and can contain wood neatly, compared to loose piles or logs strewn in the yard while you find the time to transfer your logs into a log store.
- Space saving & neatness. Instead of multiple smaller sacks stacking up, a single mammoth bag takes up a more compact footprint.
- By combining kiln-dried logs and mammoth bag delivery, many of the logistical headaches of firewood supply and storage can be simplified.
Why Buying Kiln Dried Logs in Mammoth Bags Is a Winning Combo
Here are the main benefits you get when you choose to buy kiln-dried logs delivered in a mammoth bag (from a reliable supplier):
- Efficiency and Higher Heat Output - A kiln-dried log uses more of its carbon energy to produce heat (instead of evaporating moisture). That means that per kilogram of wood, you get more usable heat. Because mammoth bags let you order in bulk, you can better capitalise on that efficiency over the season.
- Fewer Deliveries, Less Hassle - When you order smaller net bags or crates, you may need multiple deliveries (or pick-ups) across the winter. With a mammoth bag, you get a large volume in one go. That means fewer visits from delivery lorries, less time spent arranging supplies, and fewer interruptions.
- Easier Placement and Handling - Because mammoth bags have lifting loops and are designed for mechanical handling, your delivery driver can place the bag nearer to your storage or usage area (driveway, yard gate, etc.). That cuts down on how much manual labour you or your household needs to do.
- Better Storage & Protection - A large bag allows you to stack or situate logs neatly, reducing moisture ingress or the social blight of messy stacks. And since kiln-dried logs already have low moisture, the risk of decaying or spoiling is lower to begin with.
- Cost Efficiency (on a per-kWh basis) - Although the upfront cost of a mammoth bag may seem high, when you compare cost per heat unit, kiln-dried wood in bulk often works out cheaper (or at least better value) than piecemeal bagged logs or lower-grade wood. You also save on transport and handling overheads by consolidating.
- Environmental & Regulatory Compliance - As a reliable supplier of kiln-dried logs, Logs Direct adheres to sustainable sourcing practices and certifications (for example, certified forest management). By buying a larger volume up front, you reduce delivery mileage and packaging waste (fewer smaller sacks). Also, if you live in a smoke control area, using certified kiln dried logs is often a requirement or at least beneficial for compliance.
What to Look for in a Supplier (and How Logs Direct Illustrates Good Practice)
To ensure you get all the benefits above, choosing the right supplier is key. Here are features to look out for—and how the example of Logs Direct shows good practice:
- Transparency & Trust in Moisture & Quality - We openly state the moisture content (below 20%), and our logs are kiln dried to a specific standard. Also, we hold certification in the form of ‘Ready to Burn’ from Woodsure, and we are FSC Accredited, which gives you confidence. The model example clearly promotes high-quality, kiln-dried hardwood logs and positions itself as a specialist in that domain.
- Range of Delivery Sizes & Flexibility - Here at Logs Direct you can order anything from small net bags to large mammoth bags or crates of firewood. This flexibility means you’re not forced into a one-size option. Our website offers net bags, dumpy bags, crates, etc., giving you a choice depending on your space and budget.
- Strong Delivery Network & Logistics - Great wood is useless if it never arrives (or arrives soaked or damaged). Logs Direct uses dedicated delivery companies, capable of placing mammoth bags as near as possible to your property (please see our delivery page for details on deliveries and where we can drop bags). All our deliveries are typically despatched within 2 days and delivery is made the following day.
- Sustainability & Ethical Sourcing - Logs Direct is committed to sustainable forestry, replanting, and forest stewardship certifications to give you peace of mind that your heating is not contributing to irresponsible logging.
- Customer Service & Support - Because firewood is perishable and logistics can be tricky, we know you want a supplier who will talk you through best storage, delivery placement, and who handles queries or problems. Logs Direct have an excellent customer service history and pride ourselves on being on the end of the phone if you require any help with your delivery or advice. We can even help with lighting guides, which species of wood would be best for you and how to store your logs once we have delivered them to get the most from them throughout the winter period.
Practical Tips for Ordering, Storing, and Using Mammoth Bag Kiln Dried Logs
Here are some hands-on suggestions to get the most from your investment:
- Measure your space before ordering. Know how much room you have in your yard, shed, or wood store, so your delivery fits and you can access it.
- Choose the right delivery spot. Give directions to us (gates, access, drop zone) so we can place the bag in a convenient location, minimising lifting or dragging.
- Store under cover where possible. Even though the bag and kiln drying help, avoiding direct rain or puddles extends life and keeps logs drier.
- Rotate usage. Use older or more exposed logs first. Though kiln dried logs tend to retain dryness, slight differences in exposure or packing may mean some bits stay marginally drier.
- Ensure good airflow around your log pile. Ventilation helps prevent condensation and fungal growth. We advise against wrapping your bag in plastic sheeting as this can cause your logs to ‘sweat’ leading to damp and even fungal growths which can be hazardous to health.
- Check moisture occasionally. Even with kiln dried supply, after wet spells check for any damp logs, particularly around store edges, remove and dry as needed.
- Use kindling and proper lighting techniques. Good logs alone don’t guarantee a good fire. Use our quality kiln dried kindling, stack to ensure adequate airflow, and use firelighters to get a solid burn going.
Potential Drawbacks (and How to Mitigate Them)
No solution is perfect, so it’s worth being aware of possible downsides and how to address them.
- Higher upfront cost / capital outlay. Ordering a mammoth bag is a larger initial expense but you will soon recoup this via fewer deliveries, bulk efficiency, and reduced handling waste.
- Space requirement. You need room to place a large bag. If your property is small, you may find this impractical. Mitigate by choosing a smaller option like our dumpy bags.
- Delivery limitations. Some remote or constrained-exit properties may have access issues; check with our team whether we can place the bag reliably.
But in most circumstances, the benefits significantly outweigh these issues.
