Dimplex Opti-Myst 500 20-Inch Water Vapor Fireplace Cassette
The Dimplex Opti-Myst 500 20-Inch Water Vapor Fireplace Cassette creates a highly realistic fireplace experience using water vapor and light to produce a lifelike 3D flame and smoke effect. Designed for custom built-in fireplace installations, luxury feature walls, commercial spaces, and modern residential interiors, this compact cassette gives homeowners, designers, and builders the ability to create a dramatic fireplace display without gas, venting, smoke, ash, or traditional fireplace maintenance.
Unlike standard electric fireplaces that rely on flat flame projections, the Dimplex Opti-Myst 500 uses ultrasonic water vapor technology to create a moving flame illusion that rises naturally from the cassette. The result is a dimensional, elegant, and realistic fire effect that brings visual warmth and atmosphere to the space without producing traditional room heat.

Realistic Water Vapor Flame Technology
The Opti-Myst 500 is built around Dimplex’s signature Opti-Myst water vapor flame effect. Using water and light, the cassette creates the appearance of real flames and smoke without actual combustion. This makes it a beautiful alternative for spaces where a gas or wood-burning fireplace may not be practical.
The flame effect has a natural, three-dimensional look that can be viewed from multiple angles, making it especially effective in open fireplace designs, see-through installations, linear fireplace builds, and custom architectural features.
Compact 20-Inch Cassette For Custom Fireplace Builds
At approximately 20 inches wide, the Dimplex Opti-Myst 500 cassette is ideal for compact custom fireplace openings, smaller water vapor fireplace features, or modular fireplace designs where multiple cassettes are placed together to create a longer flame display.
Dimplex’s modular cassette design allows the 20-inch Opti-Myst 500 to be combined with compatible Opti-Myst cassette units to create a custom fireplace length. This makes it a strong option for luxury homes, restaurants, hotels, lounges, reception areas, and commercial interiors that need a highly customized flame feature.
No Traditional Heat Output
The Dimplex Opti-Myst 500 is designed primarily for visual ambiance and does not function as a traditional room heater. This makes it ideal for projects where the goal is to create a dramatic fireplace effect without adding warmth to the space.
Because the flame effect is created with water vapor instead of combustion, this fireplace cassette requires no chimney, gas line, venting, wood, or fuel storage. It offers the beauty of a real-looking flame with the clean simplicity of electric operation.
Ideal For Residential & Commercial Design Projects
The Opti-Myst 500 20-Inch Water Vapor Fireplace Cassette is well suited for both residential and commercial applications. Its compact size, realistic flame effect, and flexible built-in design make it a strong choice for custom fireplace walls, entertainment areas, restaurant interiors, hotel lobbies, lounges, luxury living rooms, and modern office environments.
For designers and builders, this cassette gives more creative freedom than a traditional fireplace. It can be used in open-concept layouts, contemporary room dividers, see-through fireplace concepts, or long linear installations when paired with additional compatible cassette units.
Remote Control Convenience
The Dimplex Opti-Myst 500 includes remote control operation for simple everyday use. Adjust the flame effect and enjoy the look of a real fire at the touch of a button. The water reservoir is designed for convenient refilling, allowing the cassette to create hours of realistic flame ambiance before more water is needed.
