The World's Most Authentic Fireplace Look with No Heat

Dimplex Authorized Dealer

Use the opportunity to create your own realistic fireplace in a pre-existing opening in your living area. Leaving this space empty can detract from the overall look of your room. You don't need to go through hurdles to get an authentic look of a wood-burning fire. The Dimplex Opti-Myst Vapor Casette can do this for you!

Its patented technology creates the illusion of flame and smoke rising from the center of the curved plate. It reflects light against water molecules that trick the eye into seeing smokey flames. The result is an appearance so authentic it is easily mistaken for a true fire. For a truly realistic fireplace appearance, optional accessories like log sets, pebbles, and ember glass are best to be added.

This vapor cassette is easy and safe to use. As it runs on water, it emits no heat and only needs water and electricity to run! A full water tank can run for 14 to 17 hours so you can enjoy a great uninterrupted ambiance.

Have fun customizing your own fireplace with this affordable and beautiful solution. Shop now and grab our free shipping promo! 

Note: This attractive water vapor insert does not provide heat. Halogen Lights may need to be replaced for uninterrupted use.

What's included: DFI400CH Water Vapor Fireplace, Plug, and User's Manual
