FAQs

Common Questions About the CBF700 Bioethanol Burner

What size of space is the CBF700 best suited for?

The CBF700 is designed to heat rooms of up to 50 m², making it an excellent choice for medium-to-large living spaces, open-plan areas, hotel lounges, and resort common rooms where a smaller burner would fall short.

How long can it run on a single fill?

With a 7-litre fuel tank burning at 0.7 litres per hour, the CBF700 provides between 9 and 12 hours of continuous flame per fill — ideal for extended evenings or hospitality settings where the fire needs to run through a full service.

Is the flame safe for indoor use?

Yes. Bioethanol combustion produces no smoke, soot, or harmful particulates. Adequate ventilation is recommended, but the CBF700 is entirely suitable for indoor installation across residential and hospitality spaces.

Can it be customized to suit a specific installation?

Yes, Calm offers customization options on all burners, allowing the CBF700 to be adapted to fit specific wall recesses, furniture pieces, or civil installations as per your design requirements.

What does the stainless steel construction offer in terms of durability?
