Onyx Avanti Electric Fire
The Onyx Avanti Electric Fire combines contemporary fireplace design with remarkably detailed flame visuals and convenient electric heating. Designed to create a statement focal point, the Avanti is suitable for modern living rooms, bespoke media walls and feature fireplace installations.
Available in three sizes — 110RW, 150RW and 190RW — the Avanti can be configured as a single-sided fire, a two-sided corner installation or a three-sided fire. This flexibility allows you to create a fireplace design that works with your room layout and preferred viewing angle.
Onyx Avanti Electric Fire: 3 Sizes and Installation Options
The Avanti range offers three sizes to suit different rooms and media wall designs:
- Avanti 110RW: The smallest model in the range, also available with the Milazzo Suite for a flat-wall installation.
- Avanti 150RW: A larger landscape fire for a more prominent fireplace or media wall feature.
- Avanti 190RW: The largest model, designed for expansive feature walls and wider installations.
All three sizes can be installed as a single-sided fire, a two-sided corner fire or a three-sided fire. Final dimensions and installation requirements vary by configuration, so check the manufacturer’s technical drawings before preparing the opening.
Chromalight® Plus: Realistic Flame and Lighting Effects
At the heart of the Onyx Avanti is the Chromalight® Plus LED system. It combines two independent flame effects with ember-bed up-lighting, internal log lighting and down-lighting to create a layered, three-dimensional display.
You can adjust the flame effects to suit your room and personal preference. Change the flame colours, brightness and speed to create anything from a natural-looking fire to a more contemporary display.
The standard Split Oak log-effect set features detailed logs over a glowing ember bed. An optional Split Silver Birch log-effect set is also available for a different appearance.
Convenient App and Remote Control
The Onyx Avanti can be controlled using the supplied handset or compatible app. Its controls allow you to adjust the flame and lighting effects without changing the room’s design or layout.
Features include:
- Two independent flame effects.
- Adjustable flame speed and brightness.
- Multiple flame colour choices and Spectrum mode.
- Illuminated logs and ember-bed lighting.
- Synchronisation of the different flame and lighting effects.
- Six preset combinations, with the option to save up to three personal combinations.
- Optional LED mood lighting to enhance the surrounding media wall or shelving.
The optional mood lighting system can be used around a television or along shelves to extend the ambient lighting beyond the fire itself.
Thermostatic Electric Heating
The Avanti includes a thermostatic heater rated at up to 2 kW. Set your preferred room temperature and allow the fire to adjust its heating output accordingly.
The visual flame effects can operate with or without heat, making the Avanti suitable for year-round use. Enjoy the ambience of a fire display even when additional heating is not required.
The Onyx Avanti also incorporates Ecodesign energy-saving features, including programmable heating controls.
