The recessed panels, framing details, and inward receding pilasters of the cool-touch Dimplex OptiMyst II Thompson Electric Fireplace - Burnished Walnut are remarkable but it’s the revolutionary Optimyst design that"s really going to impress. This is an innovative fireplace that takes smoke completely out of the equation thanks to ultrasonic technology that produces fine water mist in the illusion of smoke! It"s all very lifelike from the controlled flame to the glowing hand-finished logs. And it"s totally safe because behind the polished black surround and herring bone brick liner lie not hot coals, but a water tank. Measures 58.44W x 21.31D x 46.44H inches.
