How Does the Bio Flame Water Vapor Fireplace Work?
The WT48 creates its flame effect using ultrasonic water vapor technology rather than combustion.
Water is transformed into fine vapor and illuminated to create the appearance of dimensional moving flames. Because there is no burning fuel involved in creating the effect, the WT48 produces fireplace ambiance without a conventional fire.
The system also allows vapor density to be fine-tuned. The manufacturer's operating instructions document controls for increasing or decreasing vapor density and restoring the vapor-density setting to its default.
Adjustable 3D Flame Appearance
7 Adjustable Flame Colors
Choose from seven adjustable colors to coordinate the flame effect with the room, interior design, or desired atmosphere.
5 Flame Height Levels
The flame height can be adjusted through five levels, allowing the presentation to range from a lower flame effect to a more prominent visual display.
Adjustable Vapor Density
The manufacturer's operating controls provide fine adjustment of vapor density for additional control over the water vapor effect.
Wi-Fi, Remote, App & Smart-Home Control
The Bio Flame WT48 comes equipped with built-in Wi-Fi and remote-control functionality, providing several ways to operate the fireplace.
Remote Control
The included remote controller provides direct fireplace operation.
Bio Flame Smartphone App
The fireplace supports operation using The Bio Flame smartphone app.
Voice-Control Platforms
Compatible connected operation includes Google Home and Amazon Alexa.
The fireplace can also be operated using its on-unit controls.

Review the manufacturer's complete instructions, clearances, operating procedures, and installation requirements before preparing the fireplace opening or installing the WT48.
Bio Flame WT48 Water Vapor Fireplace FAQs
Does the Bio Flame WT48 produce heat?
No. The Bio Flame WT48 produces a water vapor flame effect without heat, so do not choose this model when supplemental room heating is required.
Does the Bio Flame WT48 need a chimney or vent?
No traditional combustion chimney or vent is required because the WT48 creates its flame effect using water vapor rather than burning fuel. The built-in niche still requires the manufacturer-specified open air gap at the bottom for air intake.
What are the cutout dimensions for the Bio Flame WT48?
The manufacturer-specified WT48 cutout is 1215 mm long × 180 mm wide × 250 mm deep, approximately 47.83 in. × 7.09 in. × 9.84 in. Do not use the fireplace's nominal 48-inch width as the cutout measurement.
How long does the Bio Flame WT48 run before it needs more water?
Bio Flame lists the WT48 with a 13–17-hour operating time, a 6-liter water tank, and a 3.4-liter listed refill volume. The water tank must be fully filled for first use.
Can the Bio Flame WT48 connect directly to a water supply?
Yes. The WT48 supports manual filling and a connected water supply; the manufacturer documents connecting the filling hose to a water tap for automatic filling.
Does the Bio Flame WT48 work with Alexa and Google Home?
Yes. The WT48 has built-in Wi-Fi and supports Amazon Alexa, Google Home, remote control, and smartphone app operation.
Can the Bio Flame WT48 be used as a room heater?
No. The WT48 is intended to provide fireplace ambiance rather than space heating; choose a heat-producing fireplace if room heating is a primary requirement.
Does the WT48 need electricity?
Yes. The WT48 requires an electrical connection, and Bio Flame provides specific outlet and power-connection instructions for built-in installation. Do not finalize the fireplace cavity without accounting for the electrical connection and required air intake.
Can the WT48 fireplace niche be completely sealed?
No. The manufacturer requires an open air gap at the bottom of the fireplace niche for air intake.
What comes with the Bio Flame WT48?
The supplied accessories include one remote controller, one filling hose, two handles, one plug, and one installation manual.
