FAQs

Common Questions About the CBF340 Bioethanol Burner

What types of spaces and settings is the CBF340 most suitable for?

The CBF340 is a versatile, all-round burner suited to compact living rooms, boutique hotel rooms, outdoor terraces, small dining areas, and any setting up to 20 m² where a touch of real fire is desired without the commitment of a larger installation.

How does it perform outdoors?

Bioethanol burners are naturally well-suited to outdoor use — they produce no smoke and require no fixed fuel supply. The CBF340's compact size and lightweight construction make it particularly practical for terrace placements, garden dining setups, and al fresco hospitality settings.

How long does it burn per fill?

The CBF340 provides approximately 5 hours of flame from its 2.5-litre tank, burning at 0.45 litres per hour. This is well-suited to an evening of use, whether indoors or outdoors, before a straightforward refill.

Can it be customized for a specific installation?

Yes. All Calm burners are available with customization options, and the CBF340 can be adapted to fit specific wall recesses, furniture cavities, or outdoor architectural features to match the design intent.

Is the CBF340 easy to set up?

Yes. Its modular design allows for installation within minutes once the site is prepared. Calm also provides pan-India installation services for those who prefer professional setup support.

What distinguishes the CBF340 from the CBFAB, given similar capacity?

While both share a 2.5-litre fuel tank, the CBF340 has a higher thermal output at 2.5 kW compared to the CBFAB's 1.7 kW, and a larger heating coverage of 20 m². It is the right choice when a slightly stronger heat output is needed within a compact burner format.
