About Onyx Avanti Electric Fires
Chosen by Marlow Stoves
Every Avanti shares the same Chromalight Plus LED flame system: multiple flame styles with adjustable speed rise from a glowing ember bed of ash-dusted blackened glass, with fuel-bed, down-lighting and log lighting colours across cycling spectrum modes. Three log sets cover every taste - the standard Split Oak log-effects, the Split Silver Birch upgrade, or the Luxury Logscape: real British hardwood logs, hand-assembled over hidden lighting. A programmable 2kW thermostatic heater warms the room when needed, with Adaptive Start and Open Window Detection, and the flames run with or without heat, all year.
Choose the size that fits the wall - the 110RW at 1118mm, the 150RW at 1518mm or the 190RW at 1968mm. Each installs single-sided, as a two-sided corner or as a three-sided panoramic, controlled by the Avanti app or the included Eco handset. The 110RW can also hang on a flat wall with the Milazzo Suite - no recess or building work required. Every model is Ecodesign compliant with zero direct emissions, and the range is showroom exclusive through Onyx expert retailers across the UK and Republic of Ireland.
Onyx Avanti Frequently Asked Questions
What sizes does the Onyx Avanti come in, and which should I choose?
The Avanti comes in three widths: 1118mm (110RW), 1518mm (150RW) and 1968mm (190RW), all 443mm high and 215mm deep. The right size is governed by the wall and the room: the 110RW suits TVs from 43 to 55 inches, the 150RW TVs from 50 to 65 inches, and the 190RW TVs from 65 to 75 inches.
What is the difference between the Avanti log sets?
Three fuel beds are offered across the range. The Split Oak log-effect set is fitted as standard. The Split Silver Birch log-effect set is an optional upgrade with a lighter, cooler tone. The Luxury Logscape set replaces the log-effects with real British hardwood logs, hand-assembled over hidden lighting for the most realistic bed in the range.
Can the Onyx Avanti be installed without a chimney?
Yes. Every Avanti is fully electric, so no chimney, flue or gas supply is needed - only a standard electrical connection. Each model installs single-sided, as a two-sided corner or as a three-sided panoramic from the same firebox, which keeps the fire suitable for new builds, apartments and extensions as well as period homes.
Which Onyx Avanti is best for a media wall?
All three models are designed for media walls, and Onyx pairs each with a suggested TV range: the 110RW with 43 to 55 inch TVs, the 150RW with 50 to 65 inch, and the 190RW with 65 to 75 inch. The wider the fire, the more the wall reads as a single composition, so most media-wall projects settle on the 150RW or 190RW.
Is the Onyx Avanti expensive to run?
The Avanti draws a maximum of 2kW on its heater, and its thermostatic control, Adaptive Start and Open Window Detection keep actual consumption close to what the room needs. The flames can run with the heater off for pennies-per-hour ambience, and every model is Ecodesign compliant with zero direct emissions.
Where can I see the Onyx Avanti before buying?
