Product Overview

Dimplex CDFI500-PRO-RGB Opti-Myst RGB Built-in Water Vapor Electric Fireplace, 20-Inch

The Dimplex Opti-Myst Cassette redefines modern fireplace design with patented water vapor flame technology that delivers ultra-realistic, three-dimensional flames—without heat, venting, or gas lines. Designed for complete installation flexibility, this innovative electric fireplace cassette can be integrated into see-through walls, three-sided features, custom cabinetry, or open-concept spaces, making it ideal for both residential and commercial applications.

Featuring five customizable flame colors—natural orange, blue, violet, red, and aquamarine—the Optimyst Cassette allows you to create the perfect ambiance for any setting. Enhanced with authentic crackling sound effects and full control through the Bluetooth remote or Dimplex Flame Connect App, users can adjust flame intensity, sound levels, and save personalized mood settings. With cool-to-the-touch flames, zero emissions, and maintenance-free operation, the Optimyst Cassette offers a safe, energy-efficient, and contemporary alternative to traditional fireplaces.

Excellent fire burner bundle from Warming Trends

Save yourself a headache and give those guys a call...they listen and advise you to make final decision. I am very pleased with overall burner package performance and help. Warming Trends is "Mercedes" in burners performance and quality. Thank you Jordan and rest of your team involved in my order....well done folks

Great Company to do business with.

I found out about Royal Fire Pits when I googled where to buy the Orion. I was looking for Labor Day discounts. Another company replied too late. You were prompt and I was ready, so I went with your company. Jordan was great to work with. We’ll post a picture in a few days. Thank you, Karen and Ben Lomeli

This beautiful Bordeaux Encore

This beautiful Bordeaux Encore wood burning stove was put in place yesterday with the help of a few friends. Really appreciate your help and efficiency in streamlining this order. Royal Fire Pits is fortunate to have Jordan as a representative. Your knowledge and competence about the Vermont Castings product was evident and appreciated. Thank you again for your assistance and followup. We Love it.

Amazing process, amazing finished product!

We all love the convenience of online ordering, but we also miss the personal touch of being able to call someone. Can’t thank you enough for the time spent on the phone, and appreciate how easy it was to place the order and have everything shipped. I love the output of the burner, and the black fire Glass really finished it off perfectly.

Terrific company & product

Royal Fire Pits was great to work with. The stove arrived in good order after a cross country trip. I was impressed with the quality of the cast iron and how well everything fit together. We are having a "break in" fire tonight and will shift into "catalytic mode" tomorrow. Jordon was a guiding light throughout. Many Thanks!!

Awesome fireplace

Orion Multi is an awesome fireplace and makes an immediate statement! Arrived quickly with great support from the staff when the fireplace arrived, it had been damaged in shipping. Royal fire pits was quick to remedy this and sent out a new unit the very next day.
