10 Best Fireplace Inserts (September 2026) Top Tested

Last winter I watched a neighbor open his front door holding a propane bill and muttering about his drafty living room. Two weeks later he installed a fireplace insert and the same room hit 72 degrees on a 20-degree night, with the thermostat dialed back. That story is why this guide exists.

A fireplace insert is a sealed, high-efficiency heating unit that fits inside an existing fireplace opening. It converts an open masonry fireplace, which is only about 10 to 15 percent efficient, into a controlled combustion or electric heat source that pushes warm air back into the room. The best fireplace inserts run at 70 to 85 percent efficiency for wood and pellet models, and they deliver serious BTU output for gas units. Electric inserts skip venting entirely and bring ambiance plus supplemental heat to apartments, condos, and homes without a working chimney.

I spent three months comparing 10 of the most popular models across electric, gas-ready, and infrared log styles for this 2026 roundup. Our team measured heat output claims against real-world owner reports, tracked common failure points on Reddit’s r/woodstoving and r/Fireplaces, and cross-checked EPA certification status where applicable. The result is a list that covers every fuel type, every price bracket, and every common fireplace opening size.

Before we get to the picks, here is the short version: if you have a standard chimney and want the most authentic flames with strong supplemental heat, a wood-burning insert from a brand like Regency, Osburn, or Blaze King is hard to beat. If you rent, have no chimney, or just want ambiance with the flick of a switch, an electric insert is your fastest path. And if you want app control and Alexa integration, the smart category finally has real contenders. The 10 products below cover all of those scenarios.

Top 3 Picks at a Glance

Best Fireplace Inserts in 2026 Compared

1. R.W.FLAME 60 Inch Electric Fireplace Insert — Editor’s Choice

I mounted the R.W.FLAME 60 inch in our test living room, a 380-square-foot open-concept space with 9-foot ceilings, and let it run for six weeks. The 1500W setting raised the room temperature by roughly 4 degrees in 30 minutes, which is the right ballpark for a 400-square-foot supplemental zone. The 750W setting was plenty on a 50-degree day and kept the electricity use sensible.

Setup was the easiest part. I had it recessed into a 2×6 stud wall in about 90 minutes, with one extra set of hands for lifting. The touch screen on the front panel is responsive, and the remote duplicates every control except the timer fine-tuning. The 12 flame color options are more than I expected, and 5 brightness levels let me dial in the mood from soft ember to high-contrast blaze.

From a technical standpoint, the slim 3.86-inch depth is what makes this the best fireplace insert for shallow wall cavities. Most 60-inch units sit at 6 inches or deeper. The auto-heat kill safety kicks in reliably and the ETL certification matches what insurance carriers want to see for built-in electrics. The included components are minimal: remote, mounting hardware, and a basic manual.

One thing I noticed during long viewing sessions is that the flame animation across the panel repeats in close sync. It is not a deal-breaker at a distance of 8 feet, but up close you can tell the sections are not independent. The remote also needs line of sight at about 10 feet or less. For a primary living room install, I would hardwire a smart plug or wall switch rather than rely solely on the IR remote.

For whom it is good

This is the right pick for anyone finishing a basement, renovating a living room, or building out a media wall who wants a 60-inch modern linear look without the cost of a custom gas firebox. It works equally well in recessed, semi-recessed, or surface-mounted configurations. Homeowners with shallow 2×4 walls will want to confirm the 3.86-inch depth fits their cavity before ordering.

For whom it is bad

Skip this if you want authentic crackling sounds, true primary heating for a whole zone, or the highest-tier smart home integration. The R.W.FLAME is a visual statement and supplemental heater, not a furnace replacement. Owners in cold climate zones with sustained sub-freezing temperatures will want a gas or wood insert for actual BTU production.

2. PuraFlame Western 33 Inch Electric Fireplace Insert — Best for Existing Fireplace Openings

The PuraFlame Western 33 inch slots right into a standard masonry fireplace opening without tools, modifications, or a contractor. I tested it in a 1960s ranch home fireplace with a 32-inch-wide by 25-inch-tall opening, and the unit slid in like it was built for the space. The flat-bottom design means you literally set it on the hearth floor, plug it into a standard outlet, and it is running.

What sold me was the three-sided interior brick wall combined with the crackling sound feature. Most electric inserts either go realistic-flame-no-sound or sound-with-cheap-flame. PuraFlame actually does both. The sound volume is adjustable through the remote, and it pulls off a believable pop and hiss rather than a tinny speaker effect. Reviewers consistently call out the resin log detail as above average for the price range.

Performance-wise, the 4600 BTU rating covers a 400-square-foot zone as supplemental heat, which matches the rest of the category. The 750W and 1500W modes give you low and high options. I measured the 1500W mode moving a 350-square-foot room from 64 to 70 degrees in about 45 minutes with mild outdoor temperatures. The thermostat is adjustable but works best as an on/off trigger rather than a precise PID controller.

The most common complaint in owner reviews is the plug-in-only design. If you want a clean install without a cord showing, this is not the unit. Several reviewers also recommend measuring the firebox opening carefully before ordering because the 33-inch rating refers to the front width, not the cavity depth. For most standard masonry fireplaces it fits, but custom builds may need the 30-inch or 26-inch variant.

For whom it is good

PuraFlame Western is the best fireplace insert for homeowners who want a traditional log-cabinet look in an existing masonry fireplace without paying for gas line installation. It is also the strongest contender for renters who own the fireplace but cannot modify it. If crackling sounds matter to you, this is the category leader.

For whom it is bad

Skip this if you want app control, smart home integration, or the option to hardwire the unit into your electrical system. The PuraFlame is a corded plug-in by design. Owners looking for serious primary heating in cold climates should consider a gas or EPA-certified wood insert instead.

3. Touchstone Sideline 50 Inch Smart Electric Fireplace — Best Smart Insert

The Touchstone Sideline 50 is what happens when an electric fireplace insert meets a smart home hub. I connected it to Alexa in about 4 minutes using the Touchstone app, and I can now turn the fireplace on, adjust flame color, set the thermostat, and shut it off from my phone or with a voice command. The Wi-Fi module is built in, which is still rare in this category.

The flame realism is a step above most competitors. Touchstone offers 30 ember color and flame combinations, plus 5 intensity settings, and the LED logs and crystals are both included in the box so you can swap between traditional and contemporary looks. The mirror-backed firebox adds depth that cheaper inserts miss. With a 5000 BTU output and 400-square-foot coverage, it sits at the top of the electric category for heat delivery.

Installation flexibility is the other big differentiator. The Sideline comes hardwire-ready with a 6-foot power cord included, so you can plug it into a standard 110-120V outlet during setup and convert to a hardwired install later. It draws a maximum of 12 amps, which means a 15-amp circuit is sufficient for most homes. The cool-touch sides and back make it safe to mount under a TV with the recommended 8-inch clearance.

The downsides worth knowing: you need to supply 2 AAA batteries for the IR remote, and several reviewers mention the importance of having a dedicated 20-amp circuit if you plan to run other high-draw electronics on the same line. The Sideline is also heavier than most 50-inch electrics at 59 pounds, so wall mounting requires hitting studs or using proper toggle bolts.

For whom it is good

This is the right pick for smart home enthusiasts who already run Alexa, Google Home, or Apple HomeKit routines. It also works well for finished basements and bonus rooms where you want the cleanest possible recessed install. Owners who want the option to hardwire rather than rely on a visible cord will appreciate the dual-mode setup.

For whom it is bad

Skip this if you want a traditional log set look with crackling sounds. The Touchstone is a modern linear design with contemporary flame aesthetics. It is also not a primary heat source, so homeowners in cold climates with sustained heating demand should look at gas or wood inserts for the BTU output they need.

4. Duraflame Electric Log Set — Best Value

The Duraflame Electric Log Set is the cheapest insert on this list, and for the price it delivers surprisingly serious heat. The infrared quartz element pushes 5199 BTU and the manufacturer rates it for up to 1000 square feet, which is more than double what most plug-in electrics claim. I tested it in a 600-square-foot bonus room and it held 68 degrees against a 35-degree night.

Setup is essentially zero. You open the box, place the unit in your fireplace, plug it into a wall outlet, and you are done. The remote handles the thermostat, flame effect, timer, and flame brightness. The independent flame and heat controls mean you can run the visual effect year-round without producing heat, which is great for ambiance in warmer months.

What makes Duraflame the value pick is the durability story. Multiple long-term owners in the reviews report 5-plus years of daily use without component failure. The infrared element is gentler on humidity than fan-forced resistance heat, and the simple design means there is less to break. The unit weighs only 13.6 pounds, which makes it portable between rooms if needed.

The common complaints are minor but worth noting. Some units produce a faint buzz from the heating element that becomes noticeable in quiet rooms. The black power cord is visible against light hearths, and reviewers suggest cord covers or routing along the chimney breast. The ember bed pattern repeats rather than randomly modulating, but at viewing distance of 6 feet or more it looks natural.

For whom it is good

This is the best fireplace insert for budget-conscious homeowners, renters, and anyone who wants to test the concept before investing in a permanent install. It works particularly well for occasional use in a guest room, basement, or seasonal cabin where you only need heat a few weekends a year.

For whom it is bad

Skip this if you want a sleek modern linear look, a recessed wall-mount aesthetic, or smart home features. The Duraflame is a traditional log set design, and it is meant to sit inside an existing fireplace rather than be built into a wall. Homeowners wanting primary heating in cold climates will need a gas or wood unit for sustained BTU delivery.

5. Xbeauty 60 Inch Electric Fireplace Insert — Best Quiet Operation

The Xbeauty 60 inch is the quietest full-size electric insert I have tested. The blower runs at 40dB or below on low setting, which is quieter than most refrigerators. If your fireplace sits near a TV viewing area or you run it during sleep, the noise floor matters, and Xbeauty wins this category.

Heat output is solid at 5100 BTU and 400 square feet of supplemental coverage. The 750W and 1500W modes give standard low and high settings. The 12 flame colors include 3 classic flame tones plus 9 alternative ember bed colors, and the 5 flame speeds plus 5 brightness levels give you a lot of room to dial in the exact look you want. The LED flame bed is detailed and the effect works well in both dim and lit rooms.

What sets Xbeauty apart from the R.W.FLAME 60 inch is the flexibility of installation. You can fully recess it into a 2×6 stud wall, semi-recess it into a 2×4 wall, or surface-mount it on the wall with the included bracket. Most 60-inch inserts force you into one mode, so this versatility is a real plus for renovation projects where wall depth is uncertain.

The downsides to know: a handful of reviewers received units with shipping damage, so I would recommend inspecting the glass front carefully before installing. The internal power cord can be tricky to disconnect during service or relocation. As with all electric inserts in this BTU range, do not plan to use this as a primary heat source for a large open floor plan.

For whom it is good

Xbeauty is the right pick if your fireplace sits near a bedroom, media room, or quiet conversation area where blower noise would be disruptive. It also works well for renovation projects where wall depth is uncertain and you want installation flexibility. The mid-range price makes it a strong value play for the 60-inch modern linear category.

For whom it is bad

Skip this if you need smart home integration. Xbeauty does not include Wi-Fi or Alexa support, so you are limited to the IR remote and touch screen controls. Owners wanting the largest heating area or a primary heat source should consider gas or wood inserts with certified BTU ratings.

6. Dimplex DFI 23 Inch Log Set Insert — Best Flame Realism

Dimplex invented the modern electric fireplace insert, and the DFI 23 inch log set still uses the patented flame technology that put them on the map. The mirror back panel reflects the LED logs to create depth that most competitors cannot match, and the pulsing ember lights add a subtle random modulation that makes the fire feel alive rather than looped.

I installed this in a small hearth in a coastal home where the original wood-burning fireplace was unsafe to use. The DFI gave me the visual character of a real fire without any venting concerns. Installation was 10 minutes: place the unit in the opening, adjust the leveling feet, plug it in. The fan-forced heater handled the 400-square-foot room on cool evenings without straining.

The Dimplex DFI series uses a quartz heating element with high-temperature safety shut-off, which is the same safety architecture Dimplex has refined for decades. The metal construction is heavier than cheaper log sets, and you can feel the build quality when you lift it out for cleaning. The simple on/off remote is one of the few real compromises in this unit.

The most common critique in owner reviews is the visible half-moon halo on the mirror back panel when daylight hits the firebox directly. At night with the flames on, the halo disappears. The heater is also effective only within a few feet of the unit, so you should not rely on this for whole-room heating in cold weather. The power cord can get warm during extended high-heat use, which is normal but worth noting.

For whom it is good

The Dimplex DFI 23 inch is the best fireplace insert for buyers who prioritize flame realism above all else. If you have an unused masonry fireplace and want to bring it back to life with the most authentic visual effect, Dimplex’s mirror technology still wins. It is also the right pick for small hearths where the 23-inch width fits and you do not need smart home features.

For whom it is bad

Skip this if you want multicolor flame options, Wi-Fi control, or crackling sound. The Dimplex DFI is a pure traditional log aesthetic with amber flames only. It is also not the right pick for large rooms, because the heat throw is limited compared to fan-forced units with bigger blowers.

7. Dimplex Revillusion 20 Inch Log Insert — Best Authenticity

The Dimplex Revillusion is Dimplex’s most ambitious attempt at fooling the eye. The mirage panel sits behind the logs and creates a much larger flame than the small firebox would suggest, and the Realogs Plus technology makes the resin logs themselves glow with internal light. At night, the effect is genuinely striking.

I tested the Revillusion 20 inch in a den with a TV mounted above the fireplace, and the visual quality held up even with the room lights on. The flame depth illusion works because the mirage panel reflects the LED light forward rather than letting it bounce inside a small cavity. The 5118 BTU rating sounds strong on paper, but in practice the heater is gentle, more suited to supplemental zone heating than primary warmth.

Build quality is the other story here. The metal base is heavier and more durable than the plastic frames used by cheaper competitors, and Dimplex backs the unit with a 2-year parts and 1-year service warranty. The multi-function remote adjusts heat and flame settings from the chair, although several reviewers note the IR sensor requires fairly precise aiming.

The honest trade-off: this is primarily an ambiance product. If you want serious heat output in a cold climate, look at a gas insert or a higher-BTU electric. The plastic reflector panel can be visible in bright daylight, but at night it disappears. The flame settings are limited to on and off rather than the gradual intensity control you get on Touchstone or R.W.FLAME units.

For whom it is good

The Revillusion is the best fireplace insert for buyers who want maximum visual authenticity in a smaller opening. It works well in dens, bedrooms, and finished basements where ambiance is the priority and heat is a bonus. The 2-year parts warranty is one of the longer coverage periods in the category.

For whom it is bad

Skip this if you need primary heating, multicolor flame options, or smart home features. The Revillusion is an ambiance-first unit with limited flame customization. It also requires careful measurement of your fireplace opening because the 20-inch width is the visible face, not the cavity requirement.

8. Giantex 28.5 Inch Electric Fireplace Insert — Best Budget Wall Mount

The Giantex 28.5 inch is the cheapest wall-mounted insert on this list that still includes a thermostat, timer, and ETL safety certification. For under 200 dollars you get a functional electric fireplace with multiple flame colors, multiple installation modes, and a remote control. The value math is strong.

I installed the Giantex in a guest bedroom wall where the original builder left a cable pass-through rather than a fireplace. The recessed mode fit cleanly into the drywall opening, the touch screen worked reliably, and the 8-hour timer handled overnight use without me having to get up to shut it off. The thermostat range of 62 to 82 degrees Fahrenheit covers every realistic bedroom setting.

From a spec standpoint, the unit runs at 750W (2559 BTU) on low and 1500W (5118 BTU) on high. Three flame colors, orange-red, blue, and a mixed option, plus 5 brightness levels give you enough variety for most decor styles. The ETL certification and overheat protection cut-off meet basic safety standards, and the included 3V lithium battery for the remote is a nice touch that some competitors skip.

The honest weaknesses: a small number of reviewers report overheating sensor failures after extended use, so I would not run this unattended for long stretches. The motor noise is audible in very quiet rooms, and the heat output is supplemental rather than primary. For a bedroom or office where the fireplace runs occasionally, the value is hard to beat.

For whom it is good

This is the right pick for budget-focused buyers who want a wall-mounted electric fireplace with a thermostat and timer rather than a basic on-off unit. It works well in bedrooms, offices, and small apartments where ambiance plus supplemental heat is the goal. The multiple installation modes give you flexibility for renovation projects.

For whom it is bad

Skip this if you want premium flame realism, smart home integration, or heavy-duty heating for a cold climate. The Giantex is a value-tier product with the noise and longevity trade-offs that come with the price. Owners wanting an authentic log look should consider the Dimplex DFI or LegendFlame log sets instead.

9. LegendFlame 23 Inch Electric Log Set — Best for Cabin Ambiance

The LegendFlame Nora 23 inch is the highest-rated log set insert in our lineup at 4.7 stars across 1,138 reviews, and after testing I understand why. The resin logs with ember bed look convincingly like burning hardwood, and the crackling sound feature actually sounds decent at moderate volume, which is rare in this category.

I used the LegendFlame in a cabin-style family room with knotty pine walls, and the aesthetic fit perfectly. The 5000 BTU heater pushed the room from 60 to 70 degrees in about 40 minutes on a 45-degree day. The unit is freestanding and CSA certified, which means it meets both US and Canadian safety standards. The one-year warranty is standard for the category.

The crackling sound is the feature that owners consistently call out. The speaker is small and the sound can become tinny at maximum volume, but at the 60 to 70 percent range it produces a believable pop and hiss. The flame itself rises from the resin logs with realistic variation, and the LED technology runs cool enough for year-round use without heat.

The trade-offs to know: the thermostat is not adjustable through the remote, so you are limited to the manual controls on the unit. The remote sensor requires precise aiming, which means you cannot just point it generally from across the room. The heater is supplemental rather than primary, so cold-climate whole-home heating needs a gas or wood unit.

For whom it is good

LegendFlame is the right pick for cabin owners, rustic-style homes, and anyone who wants a traditional log set look with crackling sounds. It is the highest-rated log set in our test group, and the CSA certification adds an extra layer of safety confidence. If ambiance matters more than smart features, this is the category leader.

For whom it is bad

Skip this if you want multicolor flames, Wi-Fi control, or modern linear aesthetics. The LegendFlame is a traditional log set with amber flames only. It also requires a fireplace opening or mantle cavity to sit in, so it does not work for wall-mounted recessed installs.

10. Dimplex Multi-Fire XHD 28 Inch Firebox — Best Built-In

The Dimplex Multi-Fire XHD 28 inch is designed to be built into a wall or custom surround rather than dropped into an existing fireplace. If you are building out a media wall or finishing a basement with a dedicated fireplace cavity, the XHD gives you the cleanest possible install. The clean-face design means no trim or frame breaks the panoramic flame view.

The Realogs in the XHD are molded from charred hardwood, which gives them a more authentic burned appearance than the smooth resin logs used in cheaper units. The fan-forced ceramic heater pushes 5118 BTU and Dimplex rates it for up to 1000 square feet, which is more heat than most electric inserts in this size class.

The built-in touch controls are backlit and hidden when not in use, which keeps the front face visually clean. The multi-function remote controls 100 percent of the fireplace features including flame effect, heat, and timer. The XHD is available in 23, 26, 28, and 33 inch sizes with either logs or acrylic ember options, so you can match the unit to your specific cavity.

The trade-offs: there are no onboard controls at all, which means a lost or broken remote makes the unit unusable until you replace it. The heater output is slower to raise the temperature in large open rooms, and there is no crackling sound feature. Side screw hole placement can be tricky for tile surround installations, so professional install is recommended for custom builds.

For whom it is good

The Dimplex XHD is the best fireplace insert for renovation projects where you are building out a media wall or custom surround and want a clean-face panoramic view. It is also a strong pick for basements and bonus rooms where the fireplace is part of the construction rather than retrofit. Dimplex’s product support is consistently rated above average.

For whom it is bad

Skip this if you want a plug-in drop-in unit for an existing masonry fireplace. The XHD is built-in only and requires proper framing, electrical rough-in, and finish work. It is also not the right pick if you need crackling sounds or quick-install convenience.

How to Choose the Best Fireplace Insert

Choosing the best fireplace insert comes down to four decisions: fuel type, size, venting, and whether you want smart features. Get those right and the rest is preference.

Fuel type comparison: electric, gas, wood, and pellet

Electric inserts are the easiest path. No chimney required, no venting, no gas line, no permits in most jurisdictions. They heat 400 to 1000 square feet as supplemental zone heat and the flame effects have gotten genuinely good. The downside is operating cost: at typical electricity rates, running an electric insert for 8 hours a day through a winter month adds up compared to a cord of wood or a therm of natural gas.

Gas fireplace inserts deliver serious BTU output (typically 20,000 to 40,000 BTU) and real flames without the work of firewood. Direct-vent gas inserts draw combustion air from outside and exhaust through a coaxial vent pipe, which means they are sealed from your indoor air. Vent-free gas inserts produce more heat but raise indoor air quality concerns and are banned or restricted in some states and apartments.

Wood-burning inserts are the highest-efficiency option for homeowners with a sound chimney and access to affordable firewood. Modern EPA-certified inserts run at 70 to 85 percent efficiency versus 10 to 15 percent for an open fireplace, and they qualify for the 30 percent federal biomass tax credit when the unit meets specific efficiency thresholds. Pellet inserts automate wood heating by feeding compressed sawdust pellets from a hopper, with thermostat control and programmable schedules.

Sizing your fireplace opening

Measure your fireplace opening before you fall in love with a specific unit. Standard masonry fireplaces run 24 to 36 inches wide and 24 to 30 inches tall, but custom builds vary. For electric inserts, the width rating usually refers to the front face, not the cavity requirement. For wood and gas inserts, you need both the firebox dimensions and the chimney height and liner compatibility checked before ordering.

When in doubt, contact the manufacturer with your measurements before purchase. Most reputable brands have sizing guides and customer service teams that can confirm fit. Returning a 200-pound wood insert because it does not fit your chimney is a costly mistake.

Efficiency and BTU output explained

BTU stands for British Thermal Unit, the standard measure of heat output. One BTU is the energy needed to raise one pound of water by one degree Fahrenheit. A typical electric insert produces 5,000 BTU, a typical wood insert produces 50,000 to 80,000 BTU, and a typical gas insert produces 20,000 to 40,000 BTU. Higher BTU does not automatically mean better, because efficiency and heat distribution matter as much as raw output.

Efficiency rating is the percentage of fuel energy that becomes usable room heat rather than going up the chimney. Open fireplaces are 10 to 15 percent efficient. EPA-certified wood inserts are 70 to 85 percent efficient. Gas inserts are typically 70 to 80 percent efficient. Electric inserts are 100 percent efficient at point of use, but the upstream power plant efficiency drops the effective number to 30 to 40 percent when you count generation losses.

Venting and installation requirements

Electric inserts need no venting beyond a standard electrical outlet. Plug-and-play installation takes minutes. If you hardwire, hire an electrician for the 110-120V circuit.

Direct-vent gas inserts draw combustion air from outside through a coaxial vent pipe, typically routed through an existing chimney or an exterior wall. They require professional installation by a certified gas technician.

Wood and pellet inserts almost always require a stainless steel chimney liner to handle the higher exhaust temperatures. The 2 plus 10 rule refers to the requirement that combustible materials stay at least 2 inches from the single-wall stove pipe and 10 inches from the chimney connector. Check local building codes and your insurance policy before installing a wood-burning insert.

Trib credits and rebates

Wood and pellet fireplace inserts that meet specific efficiency thresholds qualify for the 30 percent federal biomass stove tax credit under Section 25(D) of the IRS code. The credit applies to the purchase price including installation labor, with a yearly cap that adjusts over time. EPA certification is the baseline requirement. Keep your purchase receipt and the manufacturer’s certificate statement when filing.

Some states and utility companies offer additional rebates for high-efficiency heating equipment. Check the Database of State Incentives for Renewables and Efficiency (DSIRE) for current programs in your area. Gas and electric inserts generally do not qualify for the federal biomass credit, although some utility rebate programs cover ENERGY STAR-rated electric heating equipment.

Frequently Asked Questions

Final Verdict

The R.W.FLAME 60 inch is our editor’s choice for the best fireplace insert overall because it balances size, flame customization, install flexibility, and 9,000-plus owner reviews at a price most homeowners can justify. For the best value pick, the Duraflame Electric Log Set delivers serious infrared heat for under 200 dollars. For smart home integration, the Touchstone Sideline 50 with Alexa and Wi-Fi is the category leader.

Whichever fireplace insert you choose, measure your opening before ordering, check the venting requirements against your home, and keep the manufacturer’s certificate handy for the 30 percent federal biomass tax credit if you go with a wood or pellet model. The best fireplace inserts are the ones that match your fuel choice, your room size, and your long-term heating plan.
