What is the function of the ceramic stone in a Xaralyn burner?
The ceramic stone forms the heart of a bio-ethanol fireplace. This porous stone absorbs the liquid bioethanol like a sponge. Apart from evaporation, the bio-ethanol cannot escape from the burner in any other way. Unlike all other burners, we only burn the gas that is released from the evaporating bioethanol. The bio-ethanol itself does not burn. This ensures a calmer, safer, and more efficient combustion.
During operation, the ethanol gradually evaporates, creating a controlled and stable flame. This not only produces a more realistic flame effect but also results in a safe fireplace that requires no chimney.
At Xaralyn, this technology is standard in all bioethanol burners. The ceramic stone is the difference between a traditional open burner and a modern, safe, and sustainable bio-ethanol burner.

How does Xaralyn’s ceramic stone provide longer burn time and safer use?
Thanks to the ceramic stone, a Xaralyn bioethanol fireplace burns more calmly and efficiently. The ethanol is absorbed and released evenly, allowing for controlled combustion. This results in a longer burn time with less fuel consumption.
Additionally, the fireplace is much safer to use. Because the ethanol is absorbed in the stone, there is minimal risk of spilling or sudden flames. Even if the fireplace is moved or bumped, the liquid remains in the stone. This ensures that Xaralyn ceramic burners meet the highest safety standards and are suitable for daily use.

Why is a ceramic burner safer than a traditional bioethanol fireplace?
In a traditional open bioethanol burner, the fuel sits freely in the reservoir, which carries risks such as flare-ups or fire hazards when spilled.
A ceramic burner has many advantages. The fireplace uses an absorbent stone in which the ethanol is stored. Only the ethanol vapor burns, not the liquid itself. This keeps the flame stable and easy to control. The flame can be extinguished with the slider control, which cuts off airflow. There is also a separate filling hole, so you no longer fill where the flames appear. This makes a bioethanol fireplace safe to use in any room, even in households with children or pets.
How does the ceramic stone affect the heat output of the fireplace?
The ceramic stone ensures even combustion, resulting in stable heat output. The flame burns calmly and consistently without sudden peaks. This allows the bio-ethanol fireplace to provide a pleasant, continuous warmth.
Although an ethanol fireplace does not replace central heating, Xaralyn’s ceramic technology makes the heat output more efficient. The ethanol evaporates more slowly, converting more energy into heat.
What happens to the ethanol in the ceramic stone during the burning process?
During burning, the ethanol absorbed in the stone slowly turns into vapor. This vapor rises and ignites when the fireplace is lit. Only the vapor burns, not the liquid itself.
This process provides clean combustion without smoke, odor, or soot. The ceramic stone remains clean, leaving no ash or residue. This is an important advantage of Xaralyn burners, designed for long-lasting, trouble-free use.
Maintenance and lifespan of the ceramic stone
A fireplace with ceramic stone is virtually maintenance-free. The stone does not need cleaning or replacement as the ethanol burns completely.
Always use high-quality bio-ethanol (at least 96% pure) to prevent residue. This keeps the burner clean, and the stone can last for years. When used correctly, a Xaralyn ceramic stone can even last a lifetime.
Is the ceramic stone environmentally friendly and reusable?
Yes. Xaralyn’s ceramic stone is eco-friendly and reusable. The ethanol burns completely without harmful emissions, smoke, or soot. Only a small amount of CO₂ and water vapor is released, comparable to a few candles. Additionally, the stone is sustainably produced and designed to last for years in an ethanol fireplace. No disposable parts or chemicals are needed, making it a sustainable and environmentally conscious alternative to wood or gas fireplaces.

How sustainable is a bioethanol fireplace compared to wood or gas?
A bioethanol fireplace is one of the most sustainable choices for anyone seeking ambiance and comfort without emissions or smoke. While wood and gas fireplaces emit CO₂, fine dust, and soot, bio-ethanol burns cleanly.
Because bio-ethanol is produced from renewable resources such as corn, sugarcane, or grain residues, it is a CO₂-neutral alternative. Combined with Xaralyn’s ceramic stone, which optimizes fuel use, this type of fireplace is an environmentally conscious and future-proof choice.
Are bioethanol fireplaces allowed in cities with wood-burning bans?
Yes. Because a chimney-free bioethanol fireplace emits no smoke, soot, or fine dust, it is not subject to wood-burning regulations. In cities where open fireplaces or wood stoves are banned for environmental reasons, bio-ethanol fireplaces are a safe and legal alternative, providing the same warmth and coziness without affecting air quality.
How realistic is the flame of a bioethanol fireplace compared to real fire?
New users are often surprised by how realistic the flame of a bioethanol fireplace is. The flames are real, as they result from burning ethanol.
The ceramic stone ensures a calm, natural movement of the fire, similar to a wood flame. The color, intensity, and dancing glow create an authentic fire effect comparable to a traditional stove or open fireplace.

Is a chimney-free fireplace safe in apartments or small spaces?
Absolutely. A chimney-free ethanol fireplace is ideal for apartments, small homes, or spaces without a chimney. No flue is needed, and it produces no smoke or soot.
Thanks to the ceramic stone and controlled combustion, the fireplace is safe for indoor use. Ensure sufficient ventilation so the small amount of CO₂ released is safely removed.
A Xaralyn bio-ethanol fireplace is the perfect safe alternative to a wood stove in urban or compact spaces. It provides ambiance similar to a real flame, with some heat output—enough to raise the temperature in an average home by 2–3 degrees, saving on energy costs.
Lifetime guarantee on the ceramic stone
One major advantage of a Xaralyn bio-ethanol fireplace is that the ceramic stone comes with a lifetime guarantee. This ensures the heart of your fireplace remains safe and reliable for years. You can enjoy your fireplace worry-free, knowing the stone is durable, wear-resistant, and low-maintenance.
Conclusion: the ceramic stone makes the difference
The ceramic stone is the beating heart of every Xaralyn bio-ethanol fireplace. Thanks to this smart technology, you enjoy realistic flames, longer burn times, and safe use, all without a chimney.
