FAQs

Common Questions About the CBF8 Bioethanol Burner

What makes the CBF8 stand out in the Calm burner range?

The CBF8 delivers the highest thermal output in its class at 5.99 kW, making it the right choice when both visual drama and genuine heating performance are required in a large space. It's the burner for those who want real fire, at full intensity.

What size of room does the CBF8 suit?

The CBF8 is calibrated for rooms of 60 m² and above, with a minimum room size requirement of 116 m³. It is best suited to grand living spaces, double-height lobbies, resort lounges, and large open-plan hospitality areas.

How is fuel consumption managed given the higher output?

The CBF8 burns at approximately 1.1 litres per hour — faster than smaller burners, but its 8-litre capacity still provides between 7 and 11 hours of continuous flame per fill, ensuring long, uninterrupted operation.

Can it be installed without a flue or chimney?

Yes. Bioethanol burns cleanly, meaning no flue, chimney, or gas line is required. This makes the CBF8 considerably easier and less expensive to install than traditional wood-burning or gas fireplaces of comparable output.

Is it customizable for specific architectural installations?

Yes. Calm offers full customization on the CBF8, allowing it to be integrated into bespoke wall recesses, large furniture pieces, or architectural civil work to suit any design vision.

What safety considerations apply to the CBF8?

Given its higher output, the CBF8 should be installed in rooms meeting the minimum 116 m³ size requirement and should have adequate ventilation. Calm's installation team will advise on optimal placement and safety requirements as part of the installation process.
