What is the difference between RCFB Regular and RCFB Slim?

RCFB Regular uses a 193 mm body width for standard built-in projects. RCFB Slim uses a 128 mm body width for installations with less available depth.

Is SEV the same series as RCFB?

No. SEV is presented separately as the SEFIRE Smart Ethanol Vapor Fireplace series, with its own dimensions, capacities, power range, and operating instructions.

Can a smart ethanol fireplace replace a primary heater?

SEFIRE positions these products as decorative real-flame appliances that generate heat. The SEV manual specifically states that the appliance must not be used as a primary or continuous heating appliance.

Smart Ethanol Fireplace Systems

Four distinct real-flame series for different project depths.

Compare RCFB Regular, RCFB Slim, SEV Smart Ethanol Vapor Fireplace, and round intelligent ethanol models. Each series is listed separately so buyers can match the body size, capacity, control format, and installation concept to the project.

RCFB Regular Series

Standard-depth intelligent ethanol burners from 450 to 3048 mm.

The Regular range uses a 193 mm body width and is intended for standard built-in fireplace projects. Eleven catalog models cover compact rooms through long commercial feature walls; custom length can extend to 4000 mm after engineering confirmation.

RCFB Regular Application

For deeper built-in openings and longer flame lines.

Regular models suit villas, hotel lounges, showrooms and commercial feature walls where the project can accommodate the 193 mm body width and requires a larger tank than the Slim range. Final opening, ventilation, service access and finish details belong on the approved drawing.

RCFB Slim Series

A 128 mm-wide body for reduced-depth fireplace construction.

Slim is not a size label for Regular. It is a separate five-model series with a narrower body, different capacities and different consumption ranges.

Slim Application

For media walls, furniture integration and renovation work.

The 128 mm body reduces the depth demanded by the burner itself. It does not eliminate the need for clearances, ventilation, a level support base or service access. Those values depend on the confirmed model and construction detail.

SEV Smart Ethanol Vapor Fireplace

A separate six-model ethanol vapor series from 750 to 2000 mm.

SEV uses its own model names, dimensions and operating instructions. It is a decorative real-flame appliance that generates heat; the SEV manual states that it is not a primary or continuous heating appliance.

Model	Body dimensions	Capacity	Approx. burn time	Heat output
SEV-750	750 x 300 x 220 mm	2.5 L	6-10 h	2-6 kW

Manual facts: 110-240 V AC, 50-60 Hz; L1-L5 electrical power range 300-700 W; approximate flame height 3-30 cm. Actual flame appearance, runtime and output vary with model, setting, fuel and environment.

SEV Application

Premium real-flame projects requiring an ethanol vapor system.

Use the SEV range when the project specification calls for this vaporized-fuel format rather than an RCFB burner. Confirm the intended control configuration, installation opening, ventilation, service access and destination voltage before production.

Round Intelligent Ethanol

Two circular models for 360-degree centerpiece installations.

The round intelligent series is separate from all linear models. The confirmed editorial source lists 400 mm and 500 mm diameters.

Diameter	Fuel capacity	Heat output	Viewing concept	Typical use
400 mm	4.0 L	5.14 kW	360-degree circular flame	Restaurant, hotel or residential centerpiece
500 mm	6.5 L	8.36 kW	360-degree circular flame	Larger hospitality and luxury interior features

Round Application

A circular flame where a linear wall fireplace does not fit the concept.

Round intelligent units are commonly considered for central tables, island features and custom enclosures. Glass, hood, surrounding material and installation dimensions should be treated as project components rather than assumed to be included with the burner.

Selection Guide

Choose by installation constraint, not by appearance alone.

Choose RCFB Regular

When a 193 mm body fits and the project needs the broadest linear size range, larger capacities or lengths beyond 2000 mm.

Choose RCFB Slim

When installation depth is constrained and the 128 mm body materially improves the wall or furniture detail.

Choose SEV

When the specification explicitly requires the SEV smart ethanol vapor operating system and its dedicated manual.

Choose Round Intelligent

When the design calls for a central 360-degree circular flame rather than a linear wall opening.

Before quotation: send the opening dimensions, preferred series, destination voltage, finish, viewing direction, quantity, project country and required control method. Final specifications follow the confirmed quotation, approved drawing, product nameplate and delivered configuration.

Technical FAQ

Questions to resolve before specifying a smart ethanol fireplace.

Regular or Slim?

Regular has a 193 mm body width and a wider size/capacity range. Slim has a 128 mm body width and five catalog models.

Is SEV an RCFB model?

No. SEV is a separate Smart Ethanol Vapor Fireplace series with separate dimensions, power values and operating instructions.

Are output and runtime fixed?

No. Catalog values vary by model and flame level; fuel, ambient conditions and installation can also affect observed performance.

Is a chimney always unnecessary?

These are ventless ethanol appliances, but room ventilation and local building or fire requirements still require project review.

Can every size be customized?

Regular catalog material states custom length up to 4000 mm. Other custom requests require engineering and quotation confirmation.

Where are final installation dimensions confirmed?

Use the signed drawing and current manual for the exact ordered model; do not construct the opening from this overview alone.
