The Dynasty Harmony BEF is a simple solution for enhancing the ambiance and modernizing any living space. This electric fireplace is modern, ventless, and visually stunning. It is a cleaner alternative to traditional fireplaces as it emits no ashes, soot, or harmful fumes.

Designed to be fully recessed in a wall, it is an eye-catching wall accent for any room. Featuring vivid beautiful flames that flare up to the entire height of the fireplace in 3 colors on a multi-colored flame bed and with 4 sizes available, the Harmony BEF linear fireplace is sure to add warmth, ambiance, color, and style to your home.

    Love It!

    We love our fireplace, the Dynasty Harmony BEF- 57”. It was easy to install and even easier to operate, energy efficient and has a variety of options for customizing the look. In addition to controls hidden on the front of the fireplace, the Harmony BEF also comes with a remote control. The remote controls all of the features including the 3 different Flame Colors and 13 different Bed Color Options! Our favorite choice is the simple orange flame with the bed colors off, which we think provides the most realistic look. It also has a heater which is really nice on chilly days! The heater is front facing, which means you do not need to add a vent when installing! What’s great is even with the front facing heater the fireplace still mounts flush and has a thin trim, something is something I did find with electric fireplaces when shopping around.

    Exceeded our expectations!

    We spent a lot of time researching electric linear fireplaces before selecting the Dynasty Harmony BEF 57 inch and we are so impressed with the quality of this fireplace and it’s realistic flame effects. Modern Blaze listed this fireplace as one of the most realistic electric fireplaces which prompted us consider this fireplace. This thing is so well made. The log set and the reflective background really makes the flames appear to be in the middle of the logs. Definitely our favorite home improvement purchase and hope to enjoy the fireplace for many years!

    Nice Looking Fireplace, But Has Defects

    The overall look of fireplace is a very nice and gets a lot attention from our guests. However, even when the heater is off the fireplace is making a humming noise that has gotten more annoying over time. And with this fireplace you cannot change the flame intensity settings. For the price of this fireplace I do not think it worth it since it makes this annoying noise.

    Hi Andy, We value your feedback and your overall experience with us and we thank you for bringing this to our attention. It is always our goal to ensure that our customers are satisfied with our products.  We will pass this on to the manufacturer so they can improve the fireplace. The humming noise however does not seem usual. We'll have someone from our team follow up and check for any potential defects.
