Ultra FX creates a truly immersive experience
The Celsi Ultiflame Ultra FX Acero is a stylish and modern inset electric fire that combines cutting-edge flame realism with sleek design. It features Celsi’s advanced Flame Projection® Technology, which creates a deep, layered flame effect by projecting flickering flames across the back of the fire and over a bed of glowing embers. The realistic fuel bed includes hand-scorched real oak logs and ash-like embers, giving the fire a natural, wood-burning look without the mess. The wide glass viewing window—measuring 17 inches across—offers an expansive view of the flame effect, all framed in a bold 26-inch fascia available in finishes like Chrome & Satin Silver or Chrome & Black Nickel, giving it a clean, contemporary appearance.
Designed to fit a standard 16″ x 22″ fireplace opening, the fire has a 75mm inset depth and includes a 40mm spacer to make installation flexible and allow easy access to manual controls. The Acero delivers efficient heating with a thermostatic fan that offers up to 1.5kW of warmth, plus a flame-only setting for enjoying the visuals without any heat—ideal for year-round use. It can be controlled by remote, through onboard controls, or via the Celsi Smart App, and it’s compatible with both Amazon Alexa and Google Assistant, allowing voice-activated control as part of a smart home setup.
With its blend of high-end design, impressive flame realism, and convenient smart features, the Celsi Ultra FX Acero is an excellent choice for anyone looking to upgrade their fireplace with a modern electric unit that’s both visually striking and easy to use. It also comes with a 3-year manufacturer warranty for added reassurance.
