Picture the perfect fireplace: any length, any location, and any number of sides. Forget about venting, gas lines and hot glass, because they are a thing of the past. Now imagine flames made of water that you can reach out and touch. The revolutionary Opti-Myst by Dimplex reinvents the electric fireplace and makes it easier than ever to add a dramatic fire feature to any space. See-through, three-sided, open concept, the possibilities are endless, so go ahead, play with fire. Opti-Myst’s revolutionary technology uses water vapor to reflect light particles. This creates the breathtaking flame and smoke effect. 

Included spacers and slots provide customizable flame width and pattern options. Built -in water tank fills up with tap water and lets you enjoy up to 8 - 12 hours of continuous flames. Enhance your complete sensory experience with the sound of natural wood fire as the flames dance in front of your eyes. Control the flames and crackling sound effects with included remote. Change the look of your Dimplex Opti-Myst Pro Cassette Insert by simply adding optional realistic log set to the top of the unit. it instantly changes the look of your fireplace from contemporary to traditional. The log set is hand finished and painted to expertly replicate real burnt wood. Express your own unique style as the mist rises up through the rocks and the light reflects against the water molecules creating a jaw-dropping illusion of flames and smoke. The result is an appearance with unmatched realism and it will be nearly indistinguishable to a true wood-burning fire.

Caution: When determining a location for the Opti-myst® cassette, ensure that the unit will not be susceptible to drafts, vents, ceiling fans and other air currents. Similar to a candle, large movements of air will affect the unit’s ability to create and maintain the flame effect.
