An electric log insert (also called an electric log set) is a self-contained unit featuring realistic artificial logs, a glowing ember bed, and LED flame effects. It sits inside an existing fireplace opening and plugs into a standard electrical outlet. Most models include a built-in heater for supplemental warmth. It's the simplest way to convert a wood-burning or unused fireplace to electric.

Electric log sets work in virtually any fireplace opening, including wood-burning fireplaces (active or unused), gas fireplaces (with the gas professionally disconnected), and decorative/non-functional fireplace openings. The key requirement is having an electrical outlet nearby. Most log sets fit openings 16"–30" wide.

If you're converting from a wood-burning fireplace, we recommend closing or sealing the damper to prevent drafts and heat loss. You don't need to cap or remove the chimney, but sealing the damper improves energy efficiency. If converting from gas, have the gas line professionally disconnected and capped before installing electric logs.

Yes. Most electric log sets include a built-in fan-forced heater that produces 4,000–5,000 BTUs of supplemental heat—enough to warm a small to medium room (up to 400 sq. ft.). You can also run the flame effects without heat for year-round ambiance.

Realism varies by model and price point. Entry-level sets provide a pleasant glow and basic flame flicker. Mid-range and premium sets feature hand-painted logs with realistic charring and bark texture, bright pulsing ember beds, and more convincing flame movement. The most realistic option is Dimplex's Opti-Myst® technology, which uses water vapor to create flames you can actually touch.

Yes. Electric log sets are among the safest fireplace options:

• No real flames, sparks, or burning embers
• No combustion, smoke, or carbon monoxide
• Cool-touch surfaces on most models
• Automatic overheat protection
• Safe for homes with children and pets
• No chimney fire risk

Most electric log sets are designed for extended use, but we recommend following the manufacturer's guidelines. Many models include auto-shutoff timers (2, 4, or 8 hours) for safety and energy savings. Running flames only (no heat) overnight is generally safe, but always ensure the unit is in good working condition.

Minimal maintenance is needed. Occasionally dust the logs and ember bed with a soft cloth or brush. Check the power cord for damage periodically. There's no chimney to sweep, no ash to clean, and no annual inspections required. LED bulbs typically last 20,000–50,000 hours.

Measure the width, depth, and height of your fireplace opening. Choose a log set that's 2–3 inches smaller than your opening width for the most natural appearance. Most standard fireplaces accommodate 20"–26" log sets. Check product dimensions carefully before ordering.
