Are Bioethanol Fires Safe? A Comprehensive Safety Guide

Introduction: Understanding Bioethanol Fires

Ever dreamt of a cosy fire without the hassle of logs, smoke, or a chimney? That’s exactly why bioethanol fires are growing in popularity. These sleek, modern fireplaces burn a renewable alcohol-based fuel, producing real flames with no ash, soot, or harmful smoke.

But let’s address the burning question: Are bioethanol fires safe? The short answer is yes—when used properly. In this guide, we’ll break down potential risks, safety tips, and best practices so you can enjoy your fire without worry.

The Core Question: Are Bioethanol Fires Safe?

Yes, bioethanol fires are safe—if you follow the rules.

Like any open flame, they come with risks, but modern designs include safety features like spill-proof fuel tanks, automatic shut-offs, and controlled combustion. The key to safe use is proper handling, good ventilation, and following manufacturer guidelines.

So, let’s dive into what you need to know to keep your home warm and safe.

Potential Risks and Safety Concerns

Carbon Monoxide Production

Complete vs. Incomplete Combustion

Bioethanol fires burn cleanly, meaning they mainly produce carbon dioxide (CO₂) and water vapour. However, if a fire doesn’t get enough oxygen, it may burn incompletely, leading to carbon monoxide (CO) production—just like gas or wood-burning fires.

CO Levels from Bioethanol Fires

Used correctly, bioethanol fires release very little CO—far less than traditional gas or wood fires. But poor ventilation or low-quality fuel can increase CO production, which is why airflow is essential.

Comparison to Other Heating Methods

• Gas fires need flues and ventilation to prevent dangerous CO leaks.
• Wood stoves emit smoke, CO, and particulates, requiring chimneys and regular cleaning.
• Bioethanol fires burn much cleaner but still require ventilation to remain completely safe.

Fire Hazards

Risks of Spills and Fuel Handling

Bioethanol is highly flammable, and spills can ignite instantly. Never pour fuel into a hot burner—this is the leading cause of fire accidents. Always refill when the unit is completely cool, using a funnel for precision.

Flammability of Bioethanol Fuel

Unlike logs or coal, bioethanol is a liquid, making it easier to spill. Store it in a cool, sealed container, away from direct sunlight and open flames.

Unit Build Quality and Risks

Not all bioethanol fireplaces are made equal. Cheap or uncertified models might lack proper flame control or be unstable. Stick to UK/EU-certified brands for maximum safety.

Ventilation Requirements

Why Adequate Airflow Matters

Bioethanol fires consume oxygen. Without enough fresh air, you risk oxygen depletion and a CO₂ buildup, which can cause dizziness or headaches.

Room Size and Ventilation Guidelines

For safety, many manufacturers recommend a minimum room size of 20m². Keep windows slightly open or ensure air can circulate freely.

Dangers of Poor Ventilation

Using a bioethanol fire in a tiny, enclosed room without ventilation can make the air stuffy and increase CO₂ levels. If you start feeling lightheaded, get fresh air immediately.

Surface and Proximity Hazards

Burn Risks from the Unit

The exterior of a bioethanol fire can get incredibly hot—hot enough to cause burns if touched. Keep kids and pets at a safe distance.

Safe Distances from Flammable Materials

Keep at least 30cm clearance from flammable items like curtains, sofas, or rugs. Never place it near paper, blankets, or Christmas decorations.

Safe Usage Practices: Mitigating Risks

Choosing a Quality Bioethanol Fireplace

Importance of Certifications

Always check if your fireplace meets UK safety standards (BS EN 16647). Certified models have features like automatic extinguishers and spill-proof fuel tanks.

Material and Build Quality

Opt for models made from sturdy, heat-resistant materials like stainless steel or tempered glass. A strong base helps prevent accidental tipping.

Proper Fuel Handling and Storage

Refuelling Guidelines

• NEVER refuel while the fire is still burning or hot.
• Use manufacturer-approved bioethanol fuel.
• Avoid overfilling—stick to recommended fuel levels to prevent overflow.

Preventing Spills and Fires

• Store bioethanol in sealed containers away from heat sources.
• Wipe up any spills immediately and allow excess fuel to evaporate before lighting.

Ensuring Adequate Ventilation

Maximising Airflow

• Keep a window slightly open while your fire is running.
• If your room feels stuffy, turn on a fan or open a vent.

The Importance of Fresh Air Sources

A stagnant room can lead to higher CO₂ levels. Always have some kind of external airflow to prevent discomfort.

Safe Operation and Maintenance

Lighting, Extinguishing, and Cleaning

• Use a long lighter to keep your hands away from the flame.
• Always use the provided extinguisher tool instead of blowing out the fire.
• Regularly clean the burner to remove residue or soot buildup.

Inspection and Maintenance

• Check for cracks, leaks, or loose fittings.
• Make sure all safety features are working properly before each use.

Using a Carbon Monoxide Detector

Why You Need One

Even though bioethanol fires release minimal CO, a carbon monoxide detector provides extra peace of mind. Place one in the room where you use your fire.

Bioethanol Fires vs. Traditional Fireplaces: A Safety Comparison

Pros of Bioethanol Fires

✅ No need for a chimney or gas connection.
✅ Burns clean—no smoke, soot, or ash.
✅ Lower fire risk when handled properly.

Cons of Bioethanol Fires

❌ Requires careful fuel handling.
❌ Needs good ventilation for safe operation.
❌ Still an open flame, so fire risks exist.

Indoor Use Considerations

Best Practices for Indoor Use

• Ensure good ventilation—open a window slightly if necessary.
• Never leave the fire unattended when lit.

Room Size and Placement

• Make sure your room meets the minimum size requirements.
• Place the fireplace on a stable, non-flammable surface.

When Not to Use Indoors

• Avoid using in tiny, enclosed spaces with no airflow.
• Keep away from young children and pets that may accidentally knock it over.

Conclusion: Making an Informed Decision

Bioethanol fires bring style, warmth, and eco-friendliness to modern homes. When used correctly—with proper fuel handling, ventilation, and certified models—they are a safe and practical heating option.

By following basic safety guidelines, ensuring adequate ventilation, and investing in a CO detector, you can enjoy a bioethanol fire without unnecessary risks.

Stay safe, stay warm, and enjoy your fireplace responsibly!
