The Fotrose electric fire features Optimyst technology which instantly adds an inviting, warming glow to the room. Optimyst uses ultrasonic technology to create the world’s most realistic flame effect, with an ultra-fine water mist that mimics flame and smoke. As the mist rises through the logs, warm light is emitted which reflects against the water, creating an incredibly realistic 3D illusion of flames and smoke which is commonly mistaken for the real thing.
