Onyx Mirage 40i Electric Fire

The Onyx Mirage 40i is an inset electric fire built around the patented Mirage Virtual Flame System - visuals captured from a real woodburning fire, played across exposed, hand-painted logs above a pulsing ember bed. It is designed for a standard 16-inch fireplace or wall opening and needs no chimney.

The Mirage 40i is designed for a standard 16-inch fireplace or wall opening, requiring only a 75mm recess depth and no chimney. Its smart frame design conceals all fixings, making it as suited to upgrading a traditional fireplace as to a brand-new installation.

The Mirage 40i produces up to 2kW of programmable thermostatic heat, reaching and holding your preferred room temperature. Open Window Detection switches the heater off if temperatures drop rapidly, a deep-sleep mode cuts standby power after 30 minutes, and the flames run with no heat at all - with a fan-only mode for gentle air circulation.

The Mirage Virtual Flame System is Onyx's patented flame technology (GB260492): film of a perfectly constructed, authentic woodburning fire, replayed on a crystal-clear display so flames appear to lap across the fuel bed with the natural cadence of a living fire. The exposed logs in the fuel bed are modelled on the very firewood shown in the visuals.

Five flame presets are built in. High Burn, Medium Burn, Low Burn and Ember Glow mirror the natural lifecycle of a real fire, while Aurora is the contemporary alternative in blue and green. Beyond the presets, sixteen log and ember-bed lighting options, adjustable brightness and pulsing speeds let you tune the fire to the room.

Three cast iron facade designs - Arts, Chartwell and Wave - are each available in four finishes: Polished Chrome-effect, Highlight Polished, Black and Polished Brass-effect. That makes twelve combinations across the range, suiting both period and contemporary interiors.

The Mirage 40i is controlled by the included remote or the MyFlame app on iOS and Android. The app adds personalisation beyond the remote: flame presets, thermostatic heating settings, Open Window Detection, and daily and weekly schedules to fit the fire around your routine.

No. The Mirage 40i is fully electric - no chimney, flue or gas supply is required, just a standard electrical connection. The slim firebox needs only a 75mm recess, which keeps installation straightforward in almost any 16-inch opening.

Yes. The Mirage 40i runs flame-only, so the virtual flames, glowing logs and pulsing ember bed work with the heater off - the look of a fire on a summer evening, with no warmth added. A fan-only mode also circulates air gently on warmer days.

The Mirage 40i is expertly designed for easy installation - minimal work to affix to the wall, with the frame concealing all fixings - typically a competent electrician or fireplace installer.
