PERFORMANCE SPECS
Five kilos. Try it properly before you commit.
The same pellet as the 15kg bag, in a smaller bag. This is the sensible way to find out whether COFFUEL suits your appliance and how you burn, without buying a full-size bag to find out.
COFFUEL is pressed from coffee husk, the dry outer layer left at the mill once the coffee bean is removed. No trees felled, no chemical binders, no glues. It is made to the standard pellet format, so it feeds through the same hoppers and augers as wood pellets, and you can mix the two.
Time your own burn with this bag. That number, from your own appliance, is worth more than any estimate we could publish.
What it works in
- Pellet stoves
- Pellet boilers
- Pellet pizza ovens
- Pellet grills and smokers
- Pellet-compatible fire pits
- Log burners and open fires, with a pellet basket
What it does not work in
- A traditional closed charcoal BBQ on its own. Pellets need continuous airflow and top-down ignition, and a closed BBQ does not provide it. Add a pellet basket and it can be used.

How we compare
DON'T GET BURNED BY THE £300 CHIMNEY FINE.
Under the UK’s Environment Act 2021, burning traditional coal or wet wood can now result in an on-the-spot fine of up to £300. Local councils are cracking down on chimney smoke to improve air quality, making 'dirty' fuels a legal liability.
Cofuel is your legal, high-heat solution. Because our coffee pellets are precision-compressed and naturally ultra-dry (under 10% moisture), they burn hot and virtually smokeless. Switch to a 100% natural alternative that protects the air, your chimney, and the Earth.

FAQs
These questions tackle the biggest friction points a traditional wood-burner will have before trying a new, engineered fuel.
Not exactly, but it will smell much better than coal or damp wood. Because COFFUEL is made from the husk (the outer skin) rather than the roasted bean, it produces a neutral, organic aroma. It is a clean-burning scent that won't overwhelm your home or affect the taste of your food.
Yes, with one simple tool. Because pellets are smaller and denser than logs, they need a pellet basket to allow for proper airflow in a traditional grate. This keeps your Spark, Fuse, or Pro Pack contained and aerated, ensuring you reach that signature 20% higher heat output without the pellets falling through the bars.
Absolutely—they are a pro-chef favorite. COFFUEL is 100% organic and food-safe, containing zero chemical binders, glues, or additives. Because our coffee husks reach higher temperatures faster than kiln-dried wood, they are the secret weapon for hitting the 450°C floor temperature required for perfect, 60-second Neapolitan pizzas
Under the UK’s Environment Act 2021, local authorities can now issue on-the-spot civil penalties of up to £300 for chimneys emitting "substantial smoke" in Smoke Control Areas. Since COFFUEL is precision-dried to under 10% moisture, it burns virtually smokeless, helping you stay compliant, avoid fines, and keep your neighborhood air clean.
It comes down to Thermal Intensity. While kiln-dried wood remains the old industry standard, COFFUEL is engineered to burn 20% hotter. Additionally, Cofuel is 100% tree-free; we rescue agricultural waste that would otherwise rot in a landfill and release methane, a greenhouse gas 25x more potent than CO2.
Because our pellets are precision-dried for maximum power, they are "hydroscopic" (they love to absorb moisture). You should store them in a cool, dry place like a garage, shed, or a sealed container by your hearth. The benefit? COFFUEL is so dense that it takes up 50% less storage space than a traditional stack of logs.
Yes. Thanks to the high-pressure compression process, our pellets have a much higher density than natural wood logs. This means they provide a more sustained, consistent heat release. You get more energy per kilogram, meaning fewer reloads for your stove and more time enjoying the warmth.
Complete the circle! Coffee husk ash is a mineral-rich, alkaline substance high in potassium. Once cooled, it makes an excellent natural fertilizer for your garden soil or compost heap. From the earth, to your fire, and back to the garden—it’s the ultimate zero-waste heating solution.
