What Are Water Vapor and Steam Fireplaces?

Water vapor fireplaces—also known as steam fireplaces, ultrasonic water vapor fireplaces, or mist fireplaces—are electric fireplaces that use water and advanced technology to create the illusion of genuine, flickering flames. Instead of burning wood or gas, these units generate a fine, cool mist using ultrasonic atomizers. LED lights then illuminate the mist, producing a remarkably realistic, three-dimensional flame effect that is cool to the touch and safe for any indoor environment.

To see the latest in water vapor technology, explore our Dimplex Opti-myst collection, featuring industry-leading models.

While some people refer to them as “steam fireplaces,” these fireplaces actually use cool mist rather than hot steam, making them safe and comfortable for any home. Their lifelike flames and flexible, clean flame fireplace design set them apart from both traditional and standard electric fireplaces.

If you’re curious about how these compare to other modern options, our best fireplace choices article can help you decide.

How Do Water Vapor Fireplaces Work?

The magic behind water vapor fireplaces lies in their combination of water, ultrasonic technology, and LED flame technology:

  1. Water is added to a built-in reservoir or, in some models, supplied via a direct water line.
  2. An ultrasonic atomizer vibrates at high frequency, turning the water into a fine mist.
  3. LED lights, often with customizable colors and intensities, shine through and around the mist, creating the appearance of dancing, three-dimensional flames.
  4. The result is a realistic flame electric fireplace effect—beautiful, safe, and free from smoke or emissions.

Many models offer customization, allowing you to adjust flame height, brightness, and even sound effects to match your mood or décor. Discover more innovative options in our built-in electric fireplaces collection.
