Modern Flames Redstone 30" Built-in Electric Fireplace Insert - RS-3021

Hybrid-FX™ flame technology is Modern Flames’ advanced system that creates tall, vibrant, lifelike flames in an enlarged vertical viewing area for a more realistic fire look. This enhanced realism matters because it gives you the cozy ambiance of a real fireplace without the mess, venting, or safety concerns of wood or gas.

The Redstone includes a premium glowing log set and acrylic crystal ember bed that are illuminated by full-spectrum LED lighting to mimic the depth and sparkle of real burning embers. Shoppers who want a “real-fire” look like that they can choose traditional driftwood logs, modern crystals, or upgraded hand‑finished logs, so the fireplace can lean rustic, transitional, or ultra-contemporary as their style evolves.

The Redstone comes with a built‑in 5,000 BTU heater designed for supplemental zone heating, typically suitable for rooms up to around 400 square feet depending on conditions. Customers value this because it takes the chill off living rooms, bedrooms, or basements without having to raise the temperature for the entire home, making it a practical comfort upgrade as well as a design feature.

The Redstone is a built‑in, flush‑mount electric fireplace that can slide into an existing zero‑clearance wood‑burning fireplace using surround kits, or be framed into a wall with roughly 10–12 inches of depth. This gives homeowners a simple path to upgrade an old, drafty wood fireplace or create a new clean-lined feature wall, often with just standard 120 V power and no venting or gas line required

The Redstone includes touch-button controls on the unit and a sleek multi‑function remote that adjusts flame color, ember-bed color and intensity, heat level, thermostat setting, and shutoff timer. Customers appreciate that everything is accessible from the couch in a few button presses, so they can quickly change the look for movie night, lower the heat as the room warms up, or set an automatic turn‑off before bed.
