How a Bioethanol Fireplace Can Raise Room Temperature

Bioethanol fireplaces have become increasingly popular – and for good reason. They're stylish, eco-friendly, and easy to use. But can they actually heat a room? The answer is: yes!

How does it work?

A bio fireplace burns bioethanol – a clean-burning, plant-based alcohol. It produces heat, water vapor, and CO₂ – with no smoke, no soot, and no chimney needed. Nearly 100% of the heat stays in the room, making it an efficient heat source.

How much heat does it give?

Most bioethanol fireplaces produce between 1 and 4 kW of heat. That’s enough to warm up rooms between 10 and 40 m². A good rule of thumb: 1 kW heats around 10 m² of a well-insulated space.

How many degrees can it raise the temperature?

With a 3 kW fireplace in a 30 m² room, you can expect the temperature to rise by 2–4°C within 1–2 hours, depending on insulation and ambient conditions.

Is it cost-effective?

Bioethanol costs around €2–€4 per liter. One liter typically burns for 2 to 5 hours, depending on flame setting. That translates to roughly €0.60 to €2 per hour of heating – comparable to electric heaters, but with the bonus of real flames and ambiance.

Conclusion

A bioethanol fireplace isn’t just decorative – it’s functional too. It provides cozy warmth, atmosphere, and flexibility without requiring installation. Perfect for extra heat on chilly evenings.
