A 72-Inch Smart Water Vapor Fireplace for Large Feature Walls
The WT-72-BLACK combines a large-format built-in design with a manufacturer-listed 1673 mm / approximately 65.9-inch flame length, making it suitable for long fireplace features and large interior installations.
The fireplace includes seven adjustable flame colors, five flame-height levels, adjustable vapor density, built-in Wi-Fi, remote control, smartphone operation, Amazon Alexa, and Google Home compatibility.
Because the flame effect is produced using water vapor and LED illumination rather than combustion, the WT72 is intended primarily as an architectural and decorative fireplace feature.
Important buyer note: The WT-72-BLACK is a non-heating decorative fireplace. Choose this model when realistic flame ambiance is the priority rather than supplemental room heating.

How Does the Bio Flame WT72 Water Vapor Fireplace Work?
The Bio Flame WT-72-BLACK uses ultrasonic water vapor technology instead of combustion to produce its flame effect.
Water vapor and LED illumination work together to create the appearance of dimensional flames rising from the fireplace.
Because the visual effect does not require burning wood, gas, or ethanol, the WT72 does not produce heat, smoke, or combustion emissions.
Buyer decision: Choose the WT-72-BLACK when you want a large, customizable flame feature without supplemental heat. If heating performance is required, select a fireplace specifically designed to provide heat.

Flame Authority Expert Recommendation
Choose the Bio Flame WT-72-BLACK 72-Inch Smart Water Vapor Fireplace when your project calls for a large-format built-in decorative fireplace with a broad 65.9-inch flame presentation, smart-home controls, adjustable visual effects, and no heat output.
Its 72-inch format is especially well suited to long feature walls, large living rooms, hospitality environments, reception areas, and other interiors where a smaller fireplace could appear visually undersized.
The WT72 is also a strong fit when water-supply flexibility matters because the fireplace supports both manual filling and connection to a compatible water tap or line.
Do not select the WT72 when supplemental room heating is required. Before ordering, confirm the 1829 × 193 × 168 mm overall dimensions, 1824 × 180 × 250 mm cutout, required clearances, electrical setup, bottom air intake, level support surface, and selected water-supply method.

Bio Flame WT-72-BLACK Water Vapor Fireplace FAQs
Does the Bio Flame WT-72-BLACK produce heat?
No. The WT-72-BLACK creates a water vapor flame effect without producing heat; choose a heating fireplace instead if supplemental room heating is required.
Does the Bio Flame WT72 need a chimney or combustion vent?
No. The WT72 uses water vapor rather than burning fuel, so it does not require a chimney or combustion vent. The installation niche must still retain the manufacturer's required open air gap at the bottom for air intake.
How long does the Bio Flame WT72 run before it needs more water?
The manufacturer lists approximately 14–18 hours of operating time for the WT72, with a 10.8 L tank and 5.8 L refill volume. The water tank must be fully filled before first use.
What cutout size does the Bio Flame WT72 require?
The manufacturer specifies a WT72 cutout of 1824 mm long × 180 mm wide × 250 mm deep. Do not construct the finished cavity using the fireplace's overall dimensions as the cutout dimensions.
Can the Bio Flame WT72 connect directly to a water supply?
Yes. The WT72 supports manual filling and connection to a water tap or line; follow the manufacturer's filling and automatic-fill instructions for the selected configuration.
Does the Bio Flame WT72 work with Amazon Alexa and Google Home?
Yes. The WT72 includes built-in Wi-Fi and supports Amazon Alexa and Google Home, along with remote and smartphone control.
