Chris, January 30, 2026

There’s a particular magic in a fireplace – the gentle cadence of rising flames, the warm glow that settles a room, the quiet invitation to relax and be present. The Onyx Mirage 40i captures that magic with remarkable fidelity, delivering the very art of illusion in a zero‑emission, electric format – no chimney required.

Crafted from over four decades of expertise in stoves and fires, this premium 16‑inch inset electric fire marries cutting-edge technology with timeless ambience, transforming everyday living spaces into modern sanctuaries of comfort and style.

Where To Buy

The Art of Illusion

The Mirage 40i has been engineered to embody the atmosphere of a real flame, without the compromises of traditional fuel or the need for a chimney. Its advanced, patented technology recreates the look and feel of a true wood burning fire, offering on‑demand heat alongside energy‑saving innovation. The result is an immersive experience that transcends conventional electric fire design, giving you the glow, movement, and warmth you love – whenever you want it.

 

Patented Mirage Virtual Flame System

At the heart of the Mirage 40i lies the Mirage Virtual Flame System; an innovative, patented approach that uses real captured visuals of an impeccably built fire. Flames lap convincingly across hand‑painted logs, their natural rhythm and depth reflected with breathtaking realism. It’s not simply a simulation – it’s a curated illusion designed to read as authentic in light, motion and detail.

• Three cast iron designs in various finishes
• Control via Remote Control and MyFlame app

Bringing Atmosphere to Life

Whether you’re unwinding after a long day or setting the scene for a cosy evening in, the Mirage 40i offers a wealth of customisation to match your moment. Choose from 16 log and ember bed lighting options, adjust brightness and pulsing speeds, and fine-tune the ambience to your atmosphere. Its five flame presets recreate the natural stages of a real fire – from high, roaring flames to soft, glowing embers – alongside the modern Aurora alternative setting.
Enhancing this realism is the open‑fronted, hand‑painted log‑effect fuel bed, precisely modelled on the firewood shown in the flame visuals. Glass chippings and vermiculite add depth and sparkle, completing the lifelike and engaging firebox design.

Elegant Frames for Every Interior

A fireplace is as much a design statement as it is a source of comfort. The Mirage 40i is available with three distinctive cast iron façades, offered in four elegant finishes, allowing you to tailor the look to your home’s aesthetic—traditional, transitional, or unapologetically modern. Thoughtful proportions and refined detailing make it easy to create a focal point that feels naturally integrated with your interior.

Big Impact, Slim Profile

With an exceptionally slim profile requiring just 75mm of recess, the Mirage 40i is purpose‑built for a typical 16-inch fireplace opening. Whether you’re upgrading a traditional hearth or installing a brand‑new feature, its sleek form and smartly engineered frame conceal fixings for a clean, polished look. Installation is straightforward, with minimal work to affix the unit to the wall – style without the upheaval.

Comfort at Your Fingertips

From subtle ambience to instant warmth, control is elegantly simple. Use the remote control for quick adjustments or dive deeper with the MyFlame app to personalise flame presets, visuals, and heating settings – including thermostatic control and open window detection for intelligent efficiency.

The Mirage 40i puts comfort completely under your control, with thermostatic heating up to 28°C delivered by a powerful 2kW heater that reaches and maintains your ideal temperature efficiently. When warmth isn’t needed, you can still enjoy the flame visuals without heat or switch to fan‑only mode for gentle air circulation, keeping ambience alive year‑round. For added efficiency, an automatic deep sleep mode activates after 30 minutes on standby, while the app’s daily and weekly scheduling lets you tailor heating and lighting to your routine with ease.

Sustainable Comfort, Modern Efficiency

Fully Ecodesign compliant, the Mirage 40i is built for modern living, and is ideal for zonal heating, delivering warmth precisely where and when you want it. With intelligent energy‑saving features like open‑window detection and thermostatic control, you can enjoy the glow of a fire while minimising energy wastage.

As a zero‑emission electric fire, the Mirage 40i offers clean, efficient warmth with no direct emissions. Pair it with renewable energy sources such as solar or wind, and you unlock an even greener pathway to comfort – proof that sustainability and atmosphere can go hand in hand.

A New Standard of Electric Elegance

Every detail of the Onyx Mirage 40i – its lifelike flame visuals, tactile log‑effect bed, slimline fit, and intuitive controls – has been designed to elevate the electric fire experience. This is more than an appliance; it’s a centrepiece, an everyday ritual, and a forward‑thinking choice for a beautifully efficient home.
