Regency® Onyx EX150 Built-In Electric Fireplace (59")


The Regency Onyx is a built-in electric fireplace that gives you a lot of design freedom. It installs in a framed wall enclosure and can be set up as a one-sided fireplace, a two-sided corner, or a three-sided bay, so it can become a clean focal point in your design.

There's no venting and no gas line to plan around. It comes in 43, 59, and 75 inch sizes and runs on a standard 120-volt, 15-amp circuit, with Regency recommending a dedicated circuit.

What Makes the Onyx Different

  • No venting or gas. Frame it in without a chimney or gas line.
