Calculator Guide + Smokeless Cobbles
When the colder months arrive, one of the most common questions we hear is: how many logs will I need for the winter?
The answer depends on how often you light your fire, whether it’s your main heating source, and if you’re mixing logs with smokeless cobbles for longer, overnight burns. This guide will help you plan your winter fuel with confidence.
Why Plan Your Fuel Supply Early?
Making sure you order enough fuel before the peak of winter means you can:
- Avoid running short during cold spells.
- Save money compared to last-minute top-ups.
- Ensure your firewood is dry and Ready to Burn.
- Choose the right balance between softwood vs hardwood logs and smokeless cobbles.
Logs vs Smokeless Cobbles
At Peak Logs we supply both kiln-dried logs and smokeless cobbles, giving you the best of both worlds.
- Kiln-dried logs: Perfect for fast heat, great flames and that cosy woodburning atmosphere.
- Smokeless cobbles: Long-lasting, steady heat with low smoke output. Ideal for overnight or all-day burning.
Our smokeless cobbles are:
- Sold in 20kg bags
- Available in bulk quantities of 1, 10, 20 or 40 bags
- Ready to Burn certified and suitable for smoke control areas
How to Calculate Your Winter Fuel
The number of logs or cobbles you’ll need depends on usage:
- Occasional fires (2–3 nights a week): 1 bulk bag of logs may be enough.
- Regular use (most evenings): 2–3 bulk bags, or mix in cobbles for efficiency.
- Daily / overnight heating: A combination of logs and 10–20 bags of cobbles is often best.
Recommended Winter Fuel Options
| Option | Logs (Bulk Bags) | Smokeless Cobbles (20kg Bags) | Best For |
|---|---|---|---|
| Logs Only | 1–2 bulk bags | 0 | Occasional use, or those who prefer log-only fires |
| Logs + Cobbles (Balanced) | 1 bulk bag | 5–10 bags | Regular evening fires with cobbles for overnight heat |
| Logs + Cobbles (Heavy Use) | 2 bulk bags | 10–20 bags | Daily heating, including overnight burns |
Tip: One 20kg bag of cobbles typically provides 2–3 long burns of 8–10 hours each, depending on your stove.
FAQs: Logs and Cobbles
How long does a bulk bag of logs last?
For occasional use, a bulk bag can last 4–6 weeks. For daily use, it may last only 2–3 weeks.
How many cobbles should I order?
If you plan to burn overnight two or three times a week, 10 bags should see you through the season. For daily overnight burning, consider 20 bags or more.
Can I burn cobbles in my stove?
Yes, as long as your appliance is multi-fuel and rated for manufactured solid fuel. Always check your manufacturer guidelines.
Are cobbles cheaper than logs?
Per bag, cobbles may appear more expensive, but their long burn time means they often provide better value for overnight or continuous heating.
