A 3D water vapor fireplace is also called steam fireplace, using ultrasonic technology with LED light to create a 3D illusion of realistic-looking flame and smoke effect instead of actual fire. The fuel is water instead of wood, gas, or traditional electric heating elements, a water vapor fireplace uses plain tap water, which is more safe and eco-friendly. It does not create heat but make mist.

The 3D water vapor fireplace is made up of water atomised and then simulated by a light source system to achieve the effect of a real fire, and has safer features than a real fire. As the whole process of diffusion from water to fire requires the operation of various components within the fireplace, it takes 5 minutes for the flame to reach its optimum state after the first switch-on.
