TRD Insert Electric Fireplace | Convert Existing Fireplace to Electric

TRD Insert Electric Fireplace — Premium Electric Fireplace Insert for Existing Fireplace Openings

The Sierra Flame TRD Insert is a premium electric fireplace insert designed to convert an existing wood-burning or gas fireplace into a clean, modern electric hearth. With a gradient flame effect, customizable front and back lighting, and hidden venting, it's the ideal retrofit solution for homeowners who want the look and warmth of a real fireplace without the smoke, maintenance, or gas lines.

What is a Fireplace Insert? Unlike a built-in fireplace that requires framing a new opening in a wall, an electric insert slides directly into an existing fireplace cavity — the same space that once held your wood or gas fire. No new construction, no drywall work. You keep your existing surround, mantel, and hearth, and simply replace the firebox with a modern electric unit. It's the fastest path to upgrading an underused fireplace.

Why the TRD Insert Wins

Converting an existing fireplace to electric doesn't have to mean sacrificing the look. The TRD Insert's gradient flame effect is a step above the flat, uniform flames found in most electric inserts — it creates genuine depth and movement that holds up in a well-designed room. The independent front and back lighting gives you a level of ambiance control that most inserts at this price point simply don't offer.

For homeowners tired of wood mess, gas maintenance, or a dark unused fireplace opening, the TRD Insert is the most straightforward path to a premium result. Available in 30" and 34" to fit the most common existing fireplace openings.

Which Size Is Right for You?

Before ordering, measure the width of your existing fireplace opening. The TRD Insert needs to fit within the opening — leave at least 1–2" clearance on each side for proper fit and heat venting.
