Authentic flame technology
Elevating the Onyx Fusion electric fire to the pinnacle of luxury is our state-of-the-art Authentic Flame Technology, a crystal-clear, immersive display of real flame imagery.
Multiple flame options are available, from a flickering fire with sparks and wisps of smoke above, through to an elegant, swaying flame reminiscent of a gas fire and more contemporary, vivid flame effects. With an array of customisable visuals, you can set the perfect ambience for your home and mood.
Breath-taking ambience
The Fusion is brought to life by our Chromalight® Plus LED system, illuminating the fuel bed from below with an array of colours, both authentic and vibrant, or the colour changing spectrum mode for a varied and mesmerising spectacle. When the lifelike Birch Log-effect is installed, the hidden internal log lighting and Burnt Ember Logs enhance the fire’s authenticity.
Optional mood lighting.
For an extra atmospheric touch, the Fusion
can be paired with an optional Mood Lighting System, offering up to six metres of flexible LED strips that can be discreetly installed around a TV or along shelves to enhance your fire’s glow, especially suited for an impressive media wall centrepiece. For seamless control, the optional Mood Lighting System are fully controllable with the remote and app.
Choice of log sets to elevate your experience.
The Fusion 150RW elevates any room with its choice of log sets: the classic elegance of the Birch log-effect or the premium Luxury Logscape Real Woodland Log Set upgrade, made from sustainably sourced British hardwood.
Real Woodland log set.
Born from decades of wood burning mastery and handcrafted with real wood from the South West, the Luxury Logscape brings the natural beauty of the forest into your home. Further enhanced by the exclusive Authentic Flame Technology, the Fusion brings the electric fire experience to life, exquisitely fusing visual technology with luxury design.
Birch log effect
Designed to capture the ambience of a real wood burning fire, each log rests on a glowing ember bed, composed of ash-dusted blackened glass and lava rock chippings and illuminated by advanced Chromalight® Plus LED systems.
Multiple installation options
With its versatile installation options, you can tailor the Fusion 150RW electric fire to your home and style. It can be installed as a two-sided, three-sided, or inset fire, allowing seamless integration into any space.
With a slimmer depth than many other electric fires, the Onyx Fusion is particularly suitable for those where space may be limited, such as a media wall installation. With an impressive 1500mm wide viewing area, the Fusion 150RW pairs particularly well with 50” – 65” TV’s*.
*TV sizes refer to the standard diagonal screen dimension that TV manufacturers state when describing the size of their products. If sizing your existing flat screen TV, measure diagonally from the top left of the screen to the bottom right to find the TV’s advertised size. We also recommend measuring the width and height of your TV if lining it up with the Fusion below.
Ecodesign energy saving features.
You can choose to enjoy your Fusion’s effects with or without the heat, as well as set a handy countdown timer for your heating. You can also set your ideal room temperature, and the 2kW heater will adjust its power to maintain this as efficiently as possible. With Open Window Detection, if the ambient room temperature drops by 4°C within a space of eight minutes, the Fusion’s heater will automatically turn off to save energy. Heating can then be easily resumed with the remote control or app. Advanced Ecodesign energy saving features are also available when using the useful app.
Effortless control
Unlock the full potential of your Onyx Fusion electric fire via remote and app. Use the included remote handset or the innovative app, compatible with iOS and Android devices, to take precise control over the LED systems. Adjust brightness, synchronise colours, and choose from multiple flame options, all with ease and convenience.
Fully programmable thermostatic heating control
Easily create up to four daily heating schedules to suit your lifestyle, with room to save up to three weekly programs. With Adaptive Start Control, your Fusion automatically determines the correct time to turn on in advance of a pre-set time to reach your desired room temperature, ready for when you sit down and relax.
Synchronised visuals
Whether you want to choose crisp white or warm amber downlighting, or adjust the five brightness levels of any of the effects, you can effortlessly control the Fusion’s visuals using either the remote control or app. With the Birch Log-effect installed the Fusion’s sync feature enables you to synchronise the colours of the fuel bed and hidden log lighting system for a harmonious ambience.
Create and save ambient presents
Choose from the Fusion’s six pre-set visual combinations, or create and save up to three of your own for convenient access. You can cycle through 16 flame effects, two downlighting colours, all brightness levels, and independently select eight fuel bed and glowing log colours, or choose to synchronise them for perfect ambience.
