One of the most common questions we get regarding bioethanol fireplaces is whether they are dangerous or safe. It is a question that makes complete sense, as the centrepiece of a bioethanol fire is, after all, fire — which can be dangerous if mishandled.
Whether you already own a bioethanol fireplace or are considering buying one, it is important to understand the fire risks that can occur and how to avoid them. This guide covers the three most common hazards associated with bioethanol fires and how to prevent them.
How Bioethanol Fires Work
Bioethanol fires operate by burning bioethanol fuel, which is poured into a specially designed burner and ignited. The combustion process is remarkably clean, producing only carbon dioxide and water vapour as by-products. This means there is no need for a flue or vent, simplifying installation significantly.
Unlike traditional wood fires, bioethanol fires do not produce soot, ash, or smoke, making them a cleaner and more environmentally friendly heating alternative. By choosing a bioethanol fire, you are opting for a modern, efficient, and sustainable heating solution.
Safety Considerations
Whilst bioethanol fires are generally safe when used correctly, there are some important precautions to keep in mind.
Installation and Maintenance
When installing a bioethanol fireplace, always follow the manufacturer's instructions carefully. The fireplace should be placed on a stable, non-flammable surface and kept away from flammable materials such as curtains or furniture. Regular maintenance is also important — this includes cleaning the burner and surrounding area to prevent any residue buildup and checking for signs of damage or wear. Following these guidelines means you can enjoy your bioethanol fireplace with complete peace of mind.
Air Quality and Ventilation
Proper ventilation is important when using a bioethanol fireplace, as burning bioethanol produces carbon dioxide. Ensuring good airflow in the room helps prevent CO2 from building up and maintains healthy indoor air quality. This can be achieved simply by opening a window or leaving a door ajar. It is also recommended to use a bioethanol fireplace in a well-ventilated area rather than a small, enclosed space such as a bedroom or bathroom.
Hazard 1: Spilt Bioethanol During Filling
One of the most common hazards with a bioethanol fireplace is spilling fuel outside the burning chamber during filling or refilling. Bioethanol can behave differently from other liquids when poured, and it can be tricky to pour directly into the burner opening without spilling.
If you ignite a fireplace where bioethanol has been spilt outside the burning chamber, you risk creating an uncontrollable flame that cannot easily be extinguished.
To avoid this, we recommend always using a funnel or a bioethanol pump when filling your burner. See our collection of funnels and pumps here.
If you have already spilt bioethanol outside the burning chamber, wipe it away immediately and ensure there are no fuel residues on your clothing or hands before igniting the fireplace.

Hazard 2: Filling a Hot Burner
Never fill a bioethanol burner whilst it is still hot. When bioethanol ignites, it is the fumes that burn rather than the liquid itself. If you pour bioethanol into a hot burner, the fuel will begin to evaporate before you can control it — which can result in a sudden surge of flame that is extremely dangerous.
Always follow these steps when refilling your burner:
- Extinguish the flame by sliding the lid completely over the burner opening.
- Wait a minimum of 10 minutes after the fireplace has been turned off before refilling.
- Use a funnel or bioethanol pump to fill the burner.
- Check that no bioethanol has been spilt outside the burning chamber before igniting.
Following these steps ensures that you never pour bioethanol into a hot or lit burner, minimising the risk of a dangerous situation during refilling.
Hazard 3: Overfilling the Burner
Overfilling the burning chamber is another hazard to be aware of. Most burners feature a MAX indicator showing the maximum amount of fuel allowed. If your burner does not have one, a good rule of thumb is to leave at least 1 cm between the fuel level and the top edge of the chamber.
Overfilling can cause an uncontrollable flame that is difficult to extinguish, and also increases the risk of fuel spilling if the fireplace is accidentally knocked.
Many of our bioethanol fires are designed to prevent spills in the event of accidental overfilling — excess fuel runs into a secondary container rather than onto the floor. In addition, every burner is equipped with ceramic fibre cotton that helps retain the fuel inside the chamber, further minimising the risk of spillage.

Conclusion: Is a Bioethanol Fireplace Safe?
A bioethanol fireplace is no more dangerous than a regular fireplace. As long as you use common sense, follow the manufacturer's instructions, and handle the open flame with care, there is no reason to be concerned about having one in your home.
Every bioethanol fire sold at bioethanol-fireplace.co.uk is approved and certified with the German TÜV safety standard, ensuring that each product has been independently tested and meets current safety regulations.
