Description
The Art of Illusion
The Onyx Mirage 40i Electric Fire represents a new benchmark in electric fire design, combining cutting-edge technology with the ambience and warmth of a real flame. Drawing on decades of expertise in fire innovation, Onyx has transformed the beauty of living flames into a striking electric format that delivers the very art of illusion.
Powered by advanced patented technology, the Mirage 40i recreates the natural rhythm and movement of a real wood-burning fire - all with zero direct emissions. The result is a truly immersive fireside experience that transcends conventional electric fire design, offering on-demand warmth, exceptional realism, and intelligent energy efficiency.
As part of the Stovax Heating Group, Onyx brings together over 40 years of award-winning design and engineering excellence. The Mirage 40i reflects this pedigree, having been selected as a Gold Winner at the 2025 London Design Awards in the Product Design category.
An Unparalleled Flame Experience
The Rhythm of Natural Fire
The Mirage 40i offers an exceptionally authentic flame experience inspired by the natural lifecycle of a real fire. Choose from a range of flame presets, including a roaring high burn, medium and low burn settings, glowing embers, or the ultra-modern Aurora effect.
With 16 log and ember bed colour options, adjustable brightness, and pulsing speeds, the fire offers extensive customisation to suit any mood or interior. Five pre-set flame modes mirror the evolving behaviour of a real fire, delivering depth, movement, and realism unlike anything previously seen in an electric fire.
Patented Technology. Perfected Ambience.
At the heart of the Mirage 40i is the Patented Mirage Virtual Flame System, which uses real captured visuals of a perfectly constructed wood-burning fire. These visuals lap naturally across burning logs, recreating the organic cadence and movement of living flames.
Exposed, hand-painted log effects are precisely modelled to match the flame visuals, enhancing depth and realism. A carefully layered ember bed, crafted from lifelike glass and vermiculite media, completes the immersive firebox experience.
Slimline Design for Modern Living
With an exceptionally slim profile requiring just 75mm of recess, the Mirage 40i is designed to fit seamlessly into a standard 16-inch fireplace opening. This makes it ideal for upgrading traditional fireplaces or incorporating into new installations where space is limited.
Styling Options
The Mirage 40i offers three distinctive styling options, allowing it to be tailored to suit a wide range of interiors. A selection of high-quality cast iron decorative façades, available in four elegant finishes, enables a personalised fireplace design that complements both classic and contemporary homes.
Intelligent Heating & Energy Efficiency
Designed for modern living, the Mirage 40i is a zero-emission electric fire built to meet stringent Ecodesign energy standards. Intelligent features such as open window detection, thermostatic control, and Deep Sleep Mode help minimise energy usage while delivering warmth only when required.
With up to 2kW of programmable heating, the Mirage 40i is ideal for zonal heating, providing efficient, responsive warmth exactly where it’s needed.
Comfort Through the Seasons
The Mirage 40i allows the heat to be switched off entirely, enabling year-round enjoyment of the flame visuals alone. A fan-only mode provides gentle air circulation, making it perfect for use even during warmer months.
Complete Control
The Mirage 40i can be operated via the supplied remote control or the intuitive Onyx app, providing effortless access to all functions. Users can adjust flame visuals, personalise presets, manage heating settings, and activate energy-saving features with ease.
App control also enables daily and weekly scheduling, allowing the fire to integrate seamlessly into modern lifestyles and heating routines.
