Luxury Inset Gas Fires with Cutting-Edge Flame Technology

Designed for elegance and engineered for performance, the Onyx Avanti Gas Fires deliver captivating visuals and effortless comfort. These premium inset fires feature sleek, modern exteriors that blend seamlessly into contemporary interiors.

At the heart of every Avanti is the EchoFlame™ Black Glass Lining, reflecting layered, lifelike flames over a hand-painted oak log-effect bed – creating a truly picture-perfect centrepiece.

Controlled via a compact remote handset, you can adjust flames, heat output, and thermostatic settings at the touch of a button.
