Planika ONI FLOGS
Oni Flogs is a suspended automatic ethanol fireplace built on Planika's patented BEV® (Burning Ethanol Vapours) technology, which ignites only ethanol vapours rather than the liquid fuel. The result is a clean, stable flame with no smoke, ash or soot, paired with a modern suspended silhouette that works as a striking focal point in any room.
The fireplace finish is smooth, black powder-coated steel, and is available in two configurations. The flue connection version vents warm air outdoors, letting the suspended design function primarily as a visual centrepiece without affecting room temperature. The in-room vent version distributes heat through vertical slots in the upper section, turning the fireplace into a genuine heat source as well as a decorative one.
Both variants use the FLA4 FLOGS 990 burner, with realistic ceramic logs, a 5.5 L fuel tank, up to 8 hours' burn time, and a maximum heat output of 6.9 kW. The automatic refilling system allows quick, spill-free top-ups, and the fireplace can be controlled via mobile app, remote control, LCD touch panel, or an optional Smart Home System integration, with six flame height levels and a child lock.

Standard Flue Connection
This variant vents warm air outdoors through a flue, letting the suspended design serve mainly as a visual focal point rather than a heat source. It's a deliberate choice for projects where a stable, unaffected room temperature matters more than extra warmth.
With In-Room Vent
Heat is distributed through vertical slots in the upper section, turning the fireplace into a genuine heat source that warms the room without a chimney. It suits interiors where the flame is meant to be both a decorative feature and a real source of warmth.
A Realistic Ceramic Logs Fire
The ONI FLOGS suspended fireplace captures the depth and authenticity of a traditional fire, its realistic ceramic logs set within tall, dynamic flames for a natural, immersive effect. Beneath that classic appearance sits clean-burning bioethanol technology, giving a fire that feels familiar while suiting the demands of contemporary architecture and modern interiors.
ONI FLOGSis the result of extensive research and development and has been submitted for patent protection, reflecting the innovation behind its design and the uniqueness of its engineering.
Automatic refilling system
Planika was the first to introduce the automatic refilling system for bioethanol fireplaces. An automatic pump allows you to refill the fireplace quickly and effortlessly. All it takes in connecting the pump with an integrated panel and putting the other pipe to the bottle with fuel and pushing the button. Once the tank is full, the pump switches off automatically. This protects the user and the fireplace from any accidental spillage or overfilling.
