Sustainable Hearth E-FX Slim Line Series

The Sustainable Hearth E-FX Slim Line Series delivers a premium built-in fireplace look in a shallow 7-inch-deep cabinet. It is designed for condos, apartments, offices, compact media walls, and other projects where wall depth is limited but flame quality and a clean architectural finish still matter.

The series includes four models with different proportions, from compact vertical formats to wider linear designs. Each model uses the same core visual technology, illuminated log presentation, hidden heater, and flexible control options.
