Pick by opening: the Pro 1500 and Pro 1000 are large built-in fireboxes; the 40" and 20" cassettes drop into a custom surround or existing opening; the 16" cassette inserts fit a small opening or a piece of furniture.

Frequently Asked Questions
How does the Dimplex Opti-Myst create the flame effect?
Ultrasonic transducers vibrate at high frequency to create a fine water mist that rises from the ember bed. LED lighting from below illuminates the mist, creating a realistic 3D flame and smoke effect. No real fire is produced.
Does the Opti-Myst need a water line connection?
The Opti-Myst has a refillable water reservoir (no plumbing needed for residential models). Refill is required every 8-12 hours of operation. Pro-XL commercial installations can be plumbed for continuous operation.
Is the Dimplex Opti-Myst worth the premium price?
Yes if visual realism is the top priority — it's the most realistic electric fireplace technology on the market. If you mainly want a conventional electric fireplace look, the Ignite XL is a better value.
