A Smart Decorative Fireplace Without Heat or Combustion
The Bio Flame WT-18 is a built-in, ventless decorative fireplace that uses ultrasonic water vapor and LED lighting to create realistic three-dimensional flame effects. It is intended for projects where flame ambiance is the priority rather than supplemental room heating.
Because the WT-18 does not use gas, ethanol, wood, or another combustible fuel, it does not create a traditional combustion exhaust stream and does not require a conventional chimney or flue.
Seven adjustable flame colors, five flame-height levels, built-in Wi-Fi, smartphone control, a supplied remote, and compatibility with Google Home and Amazon Alexa make the WT-18 well suited to contemporary residential and commercial interior projects.
Important use classification: The WT-18 does not produce room heat. Choose this model for decorative flame ambiance and smart-home functionality, not as a primary or supplemental heating appliance.

How the Water Vapor Flame Works
The WT-18 uses ultrasonic water vapor technology to create a fine vapor that is illuminated to form a three-dimensional flame appearance.
Because the visual effect is created with vapor and lighting rather than combustion, the fireplace produces no traditional flame heat, smoke, or fuel exhaust.
Ultrasonic Vapor
A fine water mist forms the moving visual medium for the flame effect.
Illuminated 3D Flame
Lighting interacts with the vapor to create a realistic three-dimensional decorative flame appearance.
Adjustable Appearance
Seven flame colors and five flame-height levels allow the visual effect to be customized.
