FAQs

Common Questions About the CBF900 Bioethanol Burner

What makes the CBF900 particularly well-suited to premium hospitality spaces?

The CBF900 combines a strong 4.4 kW output with one of the longer burn times in the Calm range — up to 13 hours — making it ideal for hotel lounges, resort common rooms, and event spaces that need a fireplace to perform reliably through a long evening service without refuelling.

How large a space can the CBF900 comfortably heat?

The CBF900 is designed for rooms of 60 m² and above, with a minimum room size requirement of 110 m³. It is well-calibrated for large living areas, hotel suites, and expansive open-plan spaces where a smaller burner would struggle to make an impact.

Is the CBF900 noticeably different from the CBF200 or CBF8?

Each burner in the Calm range is calibrated differently. The CBF900 prioritizes a balance of high capacity and extended burn duration, making it the preferred choice when longevity of flame is as important as heating power — particularly in settings where refuelling during operation is inconvenient.

Can it be installed without specialist construction work?

Yes. Bioethanol burners require no flue, chimney, or gas connection, making them significantly simpler to install than traditional fireplaces. The CBF900's modular design allows it to be deployed within an already-prepared site in a matter of minutes.

What maintenance does the CBF900 require?

Very little. The high-grade SS-304 stainless steel construction is highly resistant to heat, corrosion, and general wear. An occasional wipe with a damp cloth is all that is needed to maintain the burner in excellent condition.

Does Calm offer installation support for the CBF900?

Yes. Calm's pan-India installation services cover the CBF900, with a dedicated team to handle placement, setup, and any on-site requirements to ensure the fireplace is ready to perform from day one.

Why choose Calm for the CBF900?

Calm is India's first truly Made-in-India fireplace brand. The CBF900 is built to the same exacting standards as every product in the range — high-grade materials, lifetime guarantee, and the kind of after-sales support that turns a one-time purchase into a lasting relationship.
