If you’ve been waiting for the next real leap forward in electric fire technology, this is it. We’re thrilled to unveil the Onyx Mirage 40i Hearth Inset Electric Fire, a truly groundbreaking new model featuring Onyx’s patented LCD flame technology - and it’s set to arrive with first UK stock dropping in January 2026.
Even better? It’s on display right now in our showroom. So if you want to see what all the buzz is about with your own eyes, come in and experience it in person. 🔥
The Art of Illusion: A New Era of Electric Flame Realism
The Mirage 40i isn’t just a fresh design refresh. It represents a completely new era of realism in electric fires.
At the heart of this model is Onyx’s patented Mirage Virtual Flame System, powered by LCD technology. Instead of relying on simulated light tricks, the Mirage 40i uses high-definition flame visuals captured from a real wood-burning fire. Real logs. Real flame movement. Real ember cycles.
Combined with a carefully built, tactile fuel bed, the result is a fire that delivers a flame picture so authentic it’s virtually indistinguishable from the real thing. Every flicker, glow, and fading ember is designed to mirror the natural lifecycle of a real log fire - just without the smoke, soot, or hassle.
Designed for a Standard 16" Opening - Perfect for Quick Upgrades
One of the best things about the Mirage 40i is how effortless it is to fit into real homes.
It’s specifically designed for a standard 16-inch fireplace opening, making it ideal if you’re:
- replacing an old open fire
- upgrading a tired inset model
- refreshing your fireplace without rebuilding the whole chimney breast
- wanting a stylish focal point with modern performance
You get the impact of a stunning new fire, while keeping installation straightforward and familiar.
Five Flame Modes for Every Mood (and Every Season)
The Mirage 40i is built for flexibility. Whether it’s a deep-winter “proper fire night” or a soft summer ambience, this model gives you full control.
Choose from five distinct flame settings:
- Roaring – bold, lively, high-energy flames
- Medium – balanced and classic
- Lazy – slow, relaxed movement for cosy evenings
- EmberGlow – low flames with a warm dying-ember effect
- Aurora – a contemporary, ethereal alternative look
With adjustable brightness, pulsing speed, and ember bed lighting choices, you can tune the fire to suit your room, your vibe, your season.
A Lifelike Firebox with Hand-Painted Log Detail
Onyx didn’t stop at the LCD visuals.
The exposed, hand-painted log-effects are precisely modelled on the same logs shown in the flame footage, which massively boosts the depth and realism when you’re sitting in front of it.
The ember bed is finished with glass chippings and vermiculite, creating a glowing, textured base that completes the illusion. In short: this doesn’t look like an electric firebox - it looks like a real one.
Smart Heating, Smarter Energy Use
Of course, realism is only half the story. The Mirage 40i brings the brains too.
Heating & control highlights:
- Up to 2kW programmable heat
- Thermostatic temperature control
- Remote handset included
- Brand-new Onyx app control
- Ambience with or without heat
- Fan-only mode for summer evenings
- Open window detection
So you can enjoy instant comfort when you want it - and clever efficiency when you don’t.
Styling Options to Match Any Interior
Whether your home leans traditional or modern, the Mirage 40i has a finish to fit.
Fascia / fret styles:
- Arts
- Chartwell
- Wave
Trim colours:
- Polished Chrome
- Highlight Polished
- Matt Black
- Polished Brass
It’s a genuinely versatile design system - sleek enough for contemporary spaces, but with enough classic options to sit beautifully in more traditional fireplace settings.
