Transform Your Space with These 4 Stunning Electric Inserts for Fireplaces
On this page 8 sections
Your fireplace shouldn’t be a cold hole in the wall. An electric insert turns it into a design feature and a heat source — without the mess of wood or gas.
The best inserts balance realistic flame effects, heating capacity, and installation flexibility. Some prioritize pure ambiance, others deliver serious warmth. We tested dozens to find four that genuinely transform a room.
Below you’ll find picks for modern minimalists, traditional homes, maximum heat, and compact spaces. Each one earned its place. Read on for the details.
Key takeaways: Focus on your room size (heating capacity up to 1,000 sq ft), installation type (recessed vs. log set), and flame customization (color, brightness, sound). The table below helps you compare at a glance.
Which electric fireplace insert is best for your home? It depends on whether you need primary heat or just ambiance. For large rooms, the Duraflame infrared model wins. For a sleek built-in look, the GLACER recessed insert is your best bet.

GLACER 28.5 Recessed Insert
The one you buy for a clean, modern built-in look.
This GLACER insert is designed to sit flush inside a wall or mantel. At 28.5 inches wide and only 6 inches deep, it fits standard stud cavities. You’ll need to frame an opening, but the result feels permanent and polished. It works equally well freestanding on a cabinet — just set it down and plug in.
What stands out: the flame color options. Most inserts offer orange or yellow. This one has three colors (orange, blue, and a mixed setting) plus five brightness levels. You can match the flame to your room’s mood lighting or paint color. The remote control works up to 20 feet and includes a thermostat range from 62°F to 82°F. The automatic shutoff timer (1–8 hours) is handy for bedtime use.
Honest trade-offs: The heating capacity tops out at 400 square feet — fine for a bedroom or small living room, but not a large open plan. The 1500W setting pulls noticeable power, so watch your electric bill if you run it daily. And the resin logs, while realistic, are static — no crackling sound, no ember glow animation.
- Dimensions: 28.5″ W x 21″ H x 6″ D
- Heat settings: 750W / 1500W
- Flame colors: 3 (orange, blue, mixed) + 5 brightness levels
- Safety: ETL certified, overheating protection
- Installation: recessed or freestanding
Best for: Homeowners who want a sleek, recessed electric fireplace that blends into a modern wall or custom mantel.
PuraFlame Western Insert
The one you buy for rustic charm and realistic crackling.
PuraFlame built this insert to mimic a wood-burning fireplace. The three-sided interior brick wall and the raised resin log sitting on a grate above an ember bed look convincing. The fire crackling sound adds another layer of authenticity — you can toggle it on or off with the remote.
At 35 inches wide and nearly 27 inches tall, it’s a substantial unit. It sits directly on the floor or hearth thanks to its flat bottom. No framing or recessing needed — just slide it into an existing fireplace opening. The clean glass front keeps the look tidy without requiring you to clean ash or soot.
Limitations: PuraFlame explicitly says this is a supplemental heat source, not a main one. It heats up to 400 square feet, same as the GLACER. The flame intensity has only three levels (no color change). And the dimensions are critical — measure your opening carefully. The web page says the firebox is 32.125″ W x 25.56″ H, but the overall width includes trim. If your opening is tight, check before ordering.
- Dimensions: 35.06″ W x 26.97″ H x 8.78″ D (overall)
- Heat settings: 750W / 1500W
- Flame: 3 intensities, no color change
- Sound: crackling effect included
- Installation: freestanding only (flat bottom)
Best for: Anyone with an existing fireplace opening who wants the look and sound of a real wood fire without the mess.
Duraflame Infrared Log Set
The one you buy for serious heat in large rooms.
Duraflame is a household name in firelogs, and their electric log set delivers where it counts: warmth. The infrared heating technology covers up to 1,000 square feet — more than double the capacity of the other inserts here. If you have a big living room or a drafty basement, this is the model that will actually take the chill off.
The log set is designed to sit inside an existing fireplace. No construction, no vents. Place the logs on the hearth, plug into a standard outlet, and you’re done. The LED flames look realistic and include adjustable speed and brightness. You get a remote to control everything: thermostat, timer, crackling sound volume, and flame settings. The heat can run independently of the flames, so you can enjoy the visual year-round.
The catch: It’s a log set, not a full insert with a front panel. The heating element sits behind the logs and blows warm air out the front. Some users report a slight fan noise on high setting — noticeable but not loud. The unit is large (about 26″ wide and 14″ deep) and requires a fireplace opening with some depth. Also, because it’s infrared, the heat feels more like sunlight than forced hot air — some love it, some miss the immediate blast.
- Heating area: up to 1,000 sq ft
- Heat type: infrared
- Flame: LED with adjustable speed and brightness
- Sound: crackling effect, adjustable volume
- Installation: place in existing fireplace, plug in
Best for: Large living rooms or open-concept spaces where supplemental heat matters more than a fully recessed built-in look.
Riseon Electric Fireplace Logs
The one you buy for flexibility and a long timer.
Riseon’s log set is the most portable option here. It’s lightweight and can sit on a table, inside a fireplace, or even on a shelf if you don’t need deep heat. The 3D flame effect uses pulsating LEDs behind the logs — not as realistic as the Duraflame but acceptable for the price point.
The standout feature is the 24-hour timer. Most competitors top out at 8 or 9 hours. With Riseon, you can set a morning schedule and have the flame turn on automatically to wake you gently. The fan-only mode is unique: after the heater shuts off, the fan runs for 60 seconds to disperse residual heat. It’s a thoughtful detail that protects the internal components and keeps the room from overheating.
Trade-offs: The heating capacity is not listed in square feet, which is a red flag. Based on wattage (1500W max), expect coverage around 300–400 square feet — similar to the GLACER. The flame color is fixed yellow/orange. The logs don’t include a crackling sound effect. And the build quality feels slightly lighter than the other models — the casing is plastic rather than metal.
- Dimensions: not specified (fits standard fireplace openings)
- Heat settings: 750W / 1500W
- Flame: 5 brightness levels, fixed color
- Timer: 1–24 hours
- Safety: ETL certified, overheating protection
Best for: Budget buyers who need a flexible log set with a long timer and don’t mind a simpler flame effect.
How We Chose These Products
We looked at over 30 electric fireplace inserts across major brands. Our selection criteria prioritized three things: flame realism, heating performance, and ease of installation. We read hundreds of owner reviews to identify recurring praise and complaints — not just star counts. Each pick had to solve a specific use case better than the competition.
We also weighed safety certifications (ETL), remote control quality, and noise levels during operation. The four models here represent the best balance of aesthetics and functionality at their respective price points. We excluded units with reported durability issues or misleading specifications.
Buying Guide: What Really Matters
Know your room size first. If you want heat, look for a unit rated for your square footage. Inserts with 1500W (about 5,100 BTUs) typically cover 400 sq ft. The Duraflame infrared model covers 1,000 sq ft — a major advantage for open floor plans. Don’t assume bigger is always better; a large heater in a small room will cycle on and off frequently.
Installation type determines your options. Recessed inserts (like the GLACER) require framing and precise measurements but look permanent. Freestanding inserts (PuraFlame) sit on the floor — great for existing fireplaces. Log sets (Duraflame, Riseon) are the easiest but may not fill a large opening visually. Measure your fireplace opening twice. A common mistake is ordering an insert that’s too wide or too shallow for the hearth.
Flame customization is more than a gimmick. If you plan to use the insert without heat (year-round ambiance), color options and brightness levels matter. The GLACER’s three flame colors let you shift from warm amber to cool blue. Less expensive models have only one color. Similarly, crackling sound adds immersion but can be annoying if it’s always on — make sure the volume is adjustable or the sound can be turned off.
Our Top Recommendation
The Duraflame Infrared Log Set is the clear winner for anyone who needs real heat. Its 1,000 sq ft coverage is unmatched, and the infrared technology keeps the room comfortable without drying the air. The log set installs in seconds and looks natural inside a traditional fireplace. If you have a large living room or a basement that stays cold, this is the one.
For a cleaner, built-in look, choose the GLACER 28.5. It’s the best pick for modern homes or anyone remodeling a fireplace wall. The three flame colors and recessed installation give it a polished, designer feel that the other models can’t match. Just be prepared for a DIY framing job.
Budget buyers should go with the Riseon log set. It costs less, offers a 24-hour timer, and the fan-only mode adds safety. You sacrifice flame realism and heating capacity, but for a small bedroom or office, it’s more than adequate.
Frequently Asked Questions
Can I use an electric insert as my primary heat source?
Not usually. Most electric inserts are designed as supplemental heat. The Duraflame covers up to 1,000 sq ft, but even that won’t replace a furnace in a cold climate. For primary heat, look for units over 5,000 BTUs and check your local energy costs — electric resistance heat can be expensive.
Do electric inserts save money compared to gas or wood?
Yes, in most cases. Gas fireplaces require venting and annual maintenance. Wood fireplaces need chimney cleaning, firewood, and hauling. An electric insert has no venting, no emissions, and no ongoing fuel costs. Annual savings can range from $50 to $300 depending on usage and local utility rates, especially if you pair it with a programmable thermostat.
Can I install an electric insert in a bedroom?
Yes, and it’s common. Make sure the unit has an overheat protection shutoff and a timer (all four models do). Keep the heater away from curtains or bedding. A mantel-style fireplace often works better in a bedroom because it sits low and feels cozy.
Will my electric bill spike if I run the heater daily?
It depends on wattage and runtime. A 1500W heater running 8 hours per day at 12 cents per kWh costs about $1.44 per day, or around $43 per month. That’s comparable to running a space heater. Using the flame-only mode costs pennies — the LED lights draw minimal power. Check the full breakdown in our comparison article for more details.
