Dimplex Opti-myst® Pro 1000 - 46” Built-in Water Vapor Electric Firebox, One or Two-Sided

Dimplex Authorized DealerThis realistic water vapor electric firebox can be installed as a single sided unit or converted to a see-through design by removing the included backer panel.

The stunning appearance and majestic design of the Opti-myst® Pro is the perfect fit for custom applications. Tailor your wall treatment around the Opti-myst® Pro for a truly built-in look.

Revolutionary ultrasonic technology is used to create the flame and smoke effect of the Dimplex® Opti-myst®. As the mist rises up the light reflects against the water molecules creating a convincing illusion of flames and smoke. The result is an appearance so authentic it will be mistaken for a true wood-burning fire.

      Great Fireplace & Great Customer Service

      The fireplace is even more amazing than we thought. The Logset added so much to the actual cassette. We're happy we bought it. The prices for both were the best out there!! The customer service was even better. Jeanny was extra helpful in helping us complete this purchase.

Customer service from Modern Blaze was impeccable throughout the whole process. Recommend this water vapor fireplace from Modern Blaze for a new home or if you are remodeling.

      Works great so far

      We've had this fireplace for a while now and it looks and works great. We have it installed in a dividing wall between our living room and a breakfast nook, it creates a very cozy atmosphere in both rooms, our 5 and 7 year old love it too. Having a real fire there wasn't an option for us with the kids, so this worked out perfect. Our contractor hardwired it in and did all the plumbing. We did get the logs and the plumbing kit that they sell here too. As far as ordering, we had it delivered within probably a week and the ordering was easy. No complaints.
