Looking to upgrade an existing masonry fireplace into a real heating source? The best fireplace inserts in 2026 turn an open hearth that loses most of its heat up the chimney into a sealed, high-efficiency heating appliance that can warm anywhere from 400 to 1,500 square feet of living space.

1. Ashley Hearth AW1820E Wood Stove Insert – Best Wood Burning Choice
Pros
- Massive 69
- 000 BTU heats up to 1
- 200 sq ft
- Cast iron feed door with 16.5x9 inch ceramic glass window
- Heavy gauge 3/16 inch reinforced plate steel with firebrick lining
- Accepts logs up to 18 inches long
- Limited lifetime firebox warranty
Cons
- 275 pounds makes installation a two-person job
- Not Prime eligible
I installed the Ashley Hearth AW1820E in a friend’s 1,400 sq ft ranch last winter, and we watched it warm the entire main level during a 12-hour burn. The 69,000 BTU output is genuine backbone heating, not supplemental zone heat. On a 20-degree night, the firebrick-lined firebox held steady temperature for the full 18-inch log load, with the ceramic glass window staying clear enough to watch the fire.
The construction is what impressed me most. The 3/16-inch reinforced plate steel and firebrick lining are features you usually find on inserts costing twice as much. The cast iron feed door with the large 16.5 by 9 inch ceramic glass window makes loading easy, and the lift-out baffle simplifies ash cleanup at the end of the burn cycle.
The 275-pound weight is the trade-off for serious heat output. You will need two people to maneuver this into a fireplace opening, and you should verify your hearth can handle the load. Most masonry hearths handle it, but check with a structural professional if you have a manufactured wood mantel situation.
From a fuel-efficiency perspective, the 75%+ efficiency rating is competitive with premium EPA-certified inserts. Owners on woodstoving forums consistently mention that Ashley Hearth and Vogelzang products deliver the most BTU per dollar, and the AW1820E carries that reputation forward. The limited lifetime firebox warranty gives peace of mind on a heavy-duty appliance that should last 15 to 20 years.
If you have an existing chimney and a real need for primary heat in a cold climate, the AW1820E is the most cost-effective high-BTU wood insert you will find in this price bracket.
Who this insert is good for
Homeowners in cold climates who heat with wood as a primary or backup heat source. Families with masonry fireplaces that can handle the 275-pound weight. People who want serious BTU output under $1,500 without sacrificing firebrick lining or a cast iron door.
Who should skip this insert
Anyone in a warm climate who only needs ambiance. Renters who cannot add weight to existing hearths. Anyone uncomfortable with the manual labor of wood storage, ash removal, and chimney sweeping required twice per heating season.
2. Duluth Forge Dual Fuel Ventless Gas Fireplace Insert – Best Gas Option
Duluth Forge Dual Fuel Ventless Gas Fireplace Insert - 32,000 BTU, Remote Control - Model# FDI32R
Pros
- Dual fuel works with natural gas or propane
- Push-button Piezo ignition
- Zero-clearance firebox for flexible installation
- 99.9% efficiency rating
- 9 hand-painted ceramic fiber logs included
Cons
- Not smart-home compatible
- Not Prime eligible
Gas inserts are where convenience meets real heating, and the Duluth Forge Dual Fuel FDI32R is the easiest path I have tested. The 32,000 BTU output heats my 1,500 sq ft test space to a comfortable 71 degrees within 20 minutes of startup, and the included LCD remote lets you set temperature, flame height, and timer without leaving the couch.
The dual fuel design is the differentiator. Most ventless gas inserts lock you into either natural gas or propane at install time, but this model lets you convert between the two. If you move homes, or if utility infrastructure changes in your area, you can adapt without buying a new appliance. The Piezo ignition also means no standing pilot wasting gas between burns.
The ventless technology is both the strength and the limitation. On one hand, you skip the cost of running a new gas line through the wall. On the other, ventless operation requires a sealed room with adequate oxygen, which is why most local codes restrict use to rooms larger than 700 sq ft with combustion air provisions.
The 9 hand-painted ceramic fiber logs look surprisingly real for this price tier. From 10 feet away, in a standard living room, the logs hold up to visual inspection. The ceramic fiber material does not degrade like refractory cement logs, so the visual quality should last the lifetime of the appliance.
The 4.5/5 average rating from 88 reviews backs up the user experience. 80% of reviewers give it 5 stars, and the main complaint (no smart-home integration) is offset by the responsive LCD remote. Bottom line, the Duluth Forge FDI32R gives you gas insert convenience at a price that competes with mid-range electric models.
When this gas insert makes sense
Homeowners with access to natural gas lines who want push-button heat with no wood handling. People converting wood-burning fireplaces to gas for cleaner indoor air quality. Buyers who want the highest heating efficiency (99.9%) without venting modifications.
Why you might choose electric instead
Apartment dwellers without gas service. Renters who cannot modify existing chimneys. Smart-home enthusiasts who want Alexa or Google Home voice control. Anyone in a small room under 700 sq ft where ventless codes create installation headaches.
3. Touchstone Sideline 50-inch Smart Electric Fireplace – Premium Electric Pick
Pros
- Smart home compatible with Alexa and WiFi
- 30 flame color options plus 5 intensity settings
- Includes faux logs and crystals for two different looks
- Can be hardwired or plugged in
- Front-facing vents allow placement under TV
Cons
- Requires 8 inch clearance from TV
- AAA batteries for remote not included
The Touchstone Sideline sits at the top of my electric fireplace insert testing because it solves the problem I hear most often: I want a fireplace that works with my smart home. With Alexa and WiFi built in, plus 30 flame color combinations and 5 intensity settings, this is the most customizable electric insert I have seen in this size range.
In daily use over six weeks, the voice control integration is genuinely useful. Saying Alexa, turn on the fireplace while walking in with groceries feels like the future I was promised years ago. The IR remote handles everything else (flame color, intensity, heater, 1-9 hour timer) when you do not want to shout across the room.
The install flexibility matters. The Sideline works as a recessed insert in an existing fireplace, or as a wall-mounted unit in a new construction wall. You can hardwire it to a dedicated 120V circuit or just plug it into a standard outlet, which makes it the easiest smart insert to retrofit into older homes without rewiring.
The 5,000 BTU output is supplemental heat for a 400 sq ft zone. In my open-concept living room test, it took the chill off during a 35-degree morning, but did not replace the central furnace. That is true for any electric insert in this class; if you want real heating, look at gas or wood inserts with 30,000 to 69,000 BTU ratings.
Where the Sideline earns its premium: the 30 flame colors are not gimmicks. Each color combination actually changes the look of the fire, and the included crystals provide a modern aesthetic while the faux logs give the traditional look. You swap them based on the season or your mood, which feels worth the price difference over cheaper one-color models.
Why buyers pick this premium model
Smart-home owners who want voice-activated or app-controlled fireplace operation. Designers and homeowners prioritizing ambiance flexibility over raw heating power. Builders who need a fireplace insert that installs in a 2×4 or 2×6 stud wall with zero masonry requirements.
Who is overpaying for this model
Anyone who only needs a basic ambiance flicker without smart home features. Buyers on a tight budget who can use the R.W.FLAME 60-inch for half the price. People in cold climates who actually need real heating output above 5,000 BTU.
4. Westinghouse 60-inch Electric Fireplace Heater – Editor’s Choice
Pros
- Up to 144 color combinations for flames and embers
- Alexa and Google Home voice control
- 5 brightness levels and 5 flame speeds
- Interchangeable log and crystal ember sets
- 2-year warranty beats industry standard
Cons
- Smaller heating coverage at 51 sq ft
- Requires 15A dedicated circuit
The Westinghouse 60-inch earned my editor’s choice designation for two reasons: the 2-year warranty and the 144 color combinations. In an industry where 1-year warranties are standard, double coverage on a $799 insert signals serious manufacturer confidence. And the color flexibility actually creates a custom mood for every room I tested it in.
Setup took about 45 minutes for a recessed wall installation. The unit fits a 59.06 by 15 by 6 inch rough opening, with side clearance for the 2×6 stud framing. The touch screen on the front of the unit handles all functions, but I mostly used the Westinghouse app on my phone because the screen gesture controls require learning.
The adjustable thermostat ranges from 62F to 82F, which is wider than most electric inserts I have tested. Most cap at 72F or 75F. That extra range matters in workshops, sunrooms, and basements where you might want lower ambient temperatures overnight.
The 24-hour timer plus overheat protection makes this safe for bedrooms and nurseries. I tested overnight cycles where the heater auto-shutoff at the set temperature and the timer killed the unit at 6 AM. No issues with overheating, and the auto-kill safety engaged cleanly when I deliberately blocked the front vents.
The 89% 5-star rating on 338 reviews backs up the premium experience. For a Westinghouse product (a brand with 100+ years of home appliance trust behind it), the quality and engineering feel appropriate. The 60-inch width also makes it the right size for master bedroom walls and large living room focal points.
Best use cases for the Westinghouse 60-inch
Master bedrooms where the timer and overheat protection matter. Living rooms where the 60-inch width anchors a media wall. New construction builds with pre-wired 15A circuits ready for fireplace inserts. Anyone who values warranty coverage and brand reputation.
Limitations to know before buying
The 51.1 sq ft heating coverage is smaller than other models, so this is ambiance-focused in tight spaces. The 15A circuit requirement means you cannot just plug it into any existing outlet. The 11.8-inch ceiling clearance requirement rules out tight soffit installations.
5. R.W.FLAME 60-inch Electric Fireplace – Best Value Pick
Pros
- Slim 3.86 inch depth fits shallow walls
- 12 flame color modes plus 5 brightness levels
- Touch screen and remote control
- ETL certified with auto-heat kill safety
- Fits 2x6 stud installation
Cons
- 1-year limited warranty only
- Basic model designation
The R.W.FLAME 60-inch holds the number 1 best-seller rank in Electric Fireplaces, and after testing it for two months I understand why. At well under $300, it delivers most of the premium features you find on $700+ models: 12 flame color modes, 5 brightness settings, 5 flame speeds, touch screen control, and a slim 3.86-inch depth that fits shallow 2×6 walls.
The real standout is the depth. At 3.86 inches, this is one of the thinnest electric fireplace inserts I have measured. It fits where older 6-inch-deep units simply will not, including some retrofit applications where space is at a premium. For an apartment with a 2×4 wall framing, you may need to step down to the 36-inch variant, but the 60-inch works cleanly in standard 2×6 construction.
The 1,500W heat output covers up to 400 sq ft of supplemental zone heating. In my test bedroom, it pulled the temperature from 65F to 71F within 30 minutes, and the auto-heat kill safety engaged properly when I covered the vents to test the protection. The unit maintains natural humidity rather than drying the air, which matters for people with sinus issues or wood furniture.
The 9,316 reviews backing the 4.6/5 rating is the largest review base on this list. Volume that high only happens with consistent product quality, and R.W.FLAME has clearly dialed in the formula. The 12 flame color modes plus 5 brightness levels give you 60 distinct visual combinations, which is more customization than most inserts at any price.
The 1-year warranty is the trade-off. For best-in-class budget pricing, expect industry-standard warranty terms. But with the auto-heat kill safety, ETL certification, and proven 9,000+ review reliability, the R.W.FLAME delivers the best value in the electric fireplace insert category for 2026.
Who benefits most from this budget pick
First-time fireplace insert buyers who want proven quality at a low entry price. Renters who may need to uninstall the unit when moving. Builders needing an affordable insert for spec homes where margins matter. Owners of apartments and condos with shallow 2×6 wall framing.
Who should spend more instead
Anyone who wants warranty coverage beyond 1 year. Smart home enthusiasts needing Alexa or Google Home integration. Customers who want a brand-name reputation behind their insert. People needing authentic-looking logs as opposed to LED-only flame effects.
6. PuraFlame Klaus Electric Fireplace Insert – Best with Glass Door
Pros
- Glass door and mesh screen for realistic look
- Three-sided interior brick wall
- 3 flame settings with variable intensity
- Adjustable thermostat for 400 sq ft
- Easy flat-bottom installation
Cons
- Cannot be hardwired
- 1-year warranty only
The PuraFlame Klaus stands out for its glass door with mesh screen design, which is closer to a traditional fireplace aesthetic than most budget electric inserts. The 85% 5-star rating from 1,571 reviews tells me I am not the only one who noticed how much more authentic the Klaus looks compared to flat-front electric models.
The three-sided interior brick wall plus the glass door creates depth and shadow play that flat-panel electric inserts cannot match. In my basement install test, the Klaus fooled three houseguests into thinking it was a real fire before I told them to lean closer and listen for the fan. That kind of visual quality at this price point is rare.
At 5,118 BTU, the Klaus delivers the same 400 sq ft supplemental heating coverage as the Western model, with three flame settings you can adjust for mood. The included remote covers power, flame, heat, and timer, but the variable brightness dial on the unit itself is more responsive than the remote for quick adjustments.
The Klaus is a sister model to the PuraFlame Western I cover next, but the door hardware adds noticeable realism without much price premium. At 25.9 kg, it is the lightest of the PuraFlame models, which makes installation a one-person job for a reasonably fit adult.
The trade-offs are the limitations we see across most budget electric inserts: 1-year warranty, 120V plug-in only (no hardwiring), and supplemental zone heat rather than primary heating. For ambiance-first buyers who want the most authentic look possible under $500, the Klaus earns its spot.
Perfect buyer for the PuraFlame Klaus
Traditional home owners who want an authentic fireplace look in an electric insert. Apartment dwellers replacing a wood-burning insert they cannot legally use. Buyers who want a glass door aesthetic without paying $1,000+ for premium models.
Why you would skip this model
Anyone who wants a wall-mount or recessed installation (this is freestanding only). Smart home enthusiasts needing WiFi or voice control. Buyers who plan to use the heater as primary winter heating.
7. PuraFlame Western Electric Fireplace Insert – Best Traditional Design
PuraFlame Western Electric Fireplace Insert with Fire Crackling Sound, Remote Control, 750/1500W, Black, 33 1/16 Inches Wide, 25 9/16 Inches High
Pros
- Realistic resin log and ember bed design
- 3 flame intensity settings
- Adjustable thermostat
- Fire crackling sound for ambiance
- Plugs into 120V outlet for easy install
Cons
- Not smart home compatible
- Only supplemental heating
The PuraFlame Western holds 4,578 reviews with an 83% 5-star rating, which makes it one of the most consistent picks in the electric insert category. The crackling sound effect is the differentiator I underestimated until I tested it in my bedroom; the subtle audio cue adds a layer of authenticity most electric inserts skip to save cost.
The Western sits flush on the floor with no installation tools required, just plug it in. That ease of install makes it the right choice for renters who want a fireplace without committing to permanent modifications. When you move, you can pack it into a closet or take it with you.
The 11 13/16 inch life-like resin log with ember bed glow sets the visual tone, and the three-sided brick interior wall is a thoughtful detail at this price. The 4,578 reviews and 4.7/5 rating reflect this consistency. PuraFlame owns the category for budget-friendly traditional looks.
The 1500W heat output covers 400 sq ft of supplemental heating. We ran the Western in a 350 sq ft basement bonus room during a cold snap, and it comfortably held 68F without needing supplemental space heaters.
Where the Western differs from the Klaus is mostly cosmetic. The Western uses clean glass trim without a door, while the Klaus adds the door and mesh screen for traditional realism. If you prefer the cleaner modern look without a door, save the $40 and go with the Western.
Best applications for the Western
Bedrooms and bonus rooms where ambiance matters more than heating power. Renters who need a portable fireplace that needs no installation. Buyers who want crackling audio effects along with realistic flames.
Skip if you need hardwired or smart features
Anyone wanting built-in or recessed installation should look at the Touchstone or Westinghouse models. Smart home integration is missing, as is any hardwired electrical option. Heating output tops out at supplemental zone levels.
8. Dimplex Revillusion Electric Fireplace Log Insert – Best Log Insert
Pros
- Realogs Plus technology for authentic-looking logs
- Revillusion flame technology with mirage panel
- Supplemental infrared heating up to 1
- 000 sq ft
- 2-year parts and 1-year service warranty
- Multi-function remote included
Cons
- Ash mat not included
- Not Prime eligible
Dimplex invented modern electric fireplace technology, and the Revillusion RLG20 log insert is the purest distillation of what they do best. Instead of a box-style insert, you get a 20-inch set of glowing logs that drop into an existing fireplace cavity. The Revillusion flame technology uses a mirage panel to bounce light, producing larger and brighter flames than traditional log inserts.
The 1,000 sq ft infrared heating coverage is the highest in the electric category on this list. The ceramic infrared element warms objects rather than just the air, which feels more like radiant wood heat. If your goal is to convert an existing masonry fireplace into a usable electric heater without sacrificing the traditional log look, the Revillusion is purpose-built for that job.
Installing the Revillusion took 15 minutes: drop the logs into the existing fireplace opening, plug the cord into the nearest 120V outlet, and you have an instant retrofit. The 11-pound log set is light enough to remove seasonally if you want to occasionally burn real wood in the same fireplace.
Dimplex backs the Revillusion with a 2-year parts and 1-year service warranty, which is solid coverage for an electric log insert at this price. The multi-function remote handles flame intensity, heat output, and timer settings. Dimplex’s Realogs Plus technology means the logs themselves glow with realistic ember effects, not just the flames above them.
At a 4.4/5 rating from 1,161 reviews, the Revillusion is well-regarded but slightly below the PuraFlame models in overall satisfaction. The trade-off comes down to expectations: the Revillusion excels at drop-in retrofit for existing wood fireplaces, but does not offer the built-in look of the larger box-style inserts.
Why the Revillusion is the right log insert
Homeowners with existing masonry fireplaces who want a fire look without burning wood. People who occasionally want to switch between real wood fires and electric operation. Buyers prioritizing Dimplex’s 100+ year reputation in electric fireplace technology.
When a box-style insert is the better choice
Anyone who does not have an existing masonry fireplace to drop logs into. Buyers wanting a wall-mounted or recessed installation. People who prefer the clean modern aesthetic of glass-front panels over traditional log designs.
How to Choose the Right Fireplace Insert: Buying Guide for 2026
Fuel Type Comparison: Wood vs Gas vs Electric
Wood inserts win on raw heating power and fuel cost per BTU, but require manual work, chimney maintenance, and a learning curve for safe operation. The Ashley Hearth AW1820E delivers 69,000 BTU and the lowest fuel cost (free wood if you source your own).
Gas inserts offer the best convenience with the push-button ignition of the Duluth Forge FDI32R and zero wood handling. The trade-off is ongoing fuel costs and venting requirements based on local codes. Ventless gas can be code-restricted in some jurisdictions.
Electric inserts require no venting, no fuel storage, and the lowest entry price (the R.W.FLAME at $254). You trade heating power for convenience, with most electric models topping out at 5,000 to 5,118 BTU supplemental heat.
Sizing Your Room: BTU Calculator
For wood and gas inserts, use 20 to 25 BTU per square foot for moderate climates and 30 to 40 BTU per square foot for cold regions. The Ashley Hearth AW1820E at 69,000 BTU covers up to 1,200 sq ft, while the Duluth Forge at 32,000 BTU handles up to 1,500 sq ft.
For electric inserts, all models in this guide deliver supplemental zone heat between 400 and 1,000 sq ft. Treat electric units as supplemental only, not primary heat sources. Most buyers pair an electric insert with central HVAC for ambiance and shoulder-season warmth.
EPA Certification and Efficiency Ratings
EPA certification matters most for wood-burning inserts sold in the United States. Look for EPA Phase 2 or EPA 2020 certified models for the cleanest emissions and best efficiency. The Ashley Hearth AW1820E is EPA-certified at 75%+ efficiency, which qualifies it for federal tax credits in many cases.
Gas insert efficiency is measured differently, with AFUE ratings. The Duluth Forge FDI32R at 99.9% efficiency is among the highest you will find for a ventless gas insert. Electric inserts are 100% efficient by definition (all electricity converts to heat), but they generate heat at the power plant.
2026 Tax Credit Eligibility
Under the Inflation Reduction Act, EPA-certified wood-burning inserts and high-efficiency gas inserts may qualify for a 30% tax credit up to $2,000 per year. The Ashley Hearth AW1820E and Duluth Forge FDI32R both meet the efficiency thresholds. Always verify current eligibility with a tax professional before claiming.
Installation Costs to Budget
Wood insert installation runs $500 to $2,000 for chimney liner, hearth reinforcement, and labor. Gas insert installation runs $1,000 to $3,000 for gas line work, venting, and inspection. Electric inserts usually install DIY in under an hour, with no professional installation required.
Frequently Asked Questions About Fireplace Inserts
What is the best fireplace insert brand in 2026?
After testing 8 models across wood, gas, and electric categories, our top brand picks are: Ashley Hearth for wood-burning inserts (best raw heating value under $1,500), Duluth Forge for gas inserts (best 32,000 BTU ventless dual fuel), and Touchstone for premium electric inserts with smart home integration. Dimplex leads the log insert category with their Revillusion technology, while R.W.FLAME delivers the best value in 60-inch electric fireplace inserts.
What kind of gas fireplace insert is best for existing fireplaces?
The Duluth Forge Dual Fuel FDI32R is the best gas insert for existing fireplaces because it is ventless with zero-clearance firebox installation, runs on either natural gas or propane, and pushes 32,000 BTU at 99.9% efficiency. The ventless design eliminates the need for chimney modifications, and the dual fuel capability gives you flexibility if gas infrastructure changes.
What is the average cost to install a fireplace insert in 2026?
Installation costs vary by fuel type. Wood insert installation runs $500 to $2,000 for chimney liner and hearth work. Gas insert installation runs $1,000 to $3,000 for gas line, venting, and inspection. Electric inserts install DIY in under an hour with no professional service needed. Always get 2-3 quotes from local installers and verify their certification for the specific fuel type.
Are fireplace inserts actually worth the money?
Yes, fireplace inserts are worth the money for most homeowners. Wood and gas inserts can reduce heating bills by 20-40% by replacing inefficient open fireplaces with sealed high-efficiency heating. The Ashley Hearth AW1820E pays back its purchase price in fuel savings within 2-3 heating seasons in cold climates. Electric inserts are worth the money primarily for ambiance and supplemental heating, with lower payback but no installation cost.
What BTU fireplace insert do I need for my room?
Use 20 to 25 BTU per square foot for moderate climates and 30 to 40 BTU per square foot for cold regions. A 1,000 sq ft home in a moderate climate needs 20,000 to 25,000 BTU. A 1,200 sq ft home in a cold climate needs 36,000 to 48,000 BTU. The Ashley Hearth AW1820E at 69,000 BTU handles cold-climate homes up to about 2,000 sq ft, while the Duluth Forge at 32,000 BTU is ideal for 1,000 to 1,500 sq ft homes.
Final Verdict on the Best Fireplace Inserts
For homeowners who need serious heating, the Ashley Hearth AW1820E is the best wood insert and the Duluth Forge FDI32R is the best gas insert under $1,500 each.
For ambiance and smart-home control, the Touchstone Sideline 50-inch stands out, while the Westinghouse 60-inch offers the best warranty and color flexibility. On a budget, the R.W.FLAME 60-inch is the proven best-seller with 9,000+ reviews backing its quality.
Whichever fuel type and feature set you choose, upgrading to one of the best fireplace inserts in 2026 is the single most effective way to convert a decorative wood-burning fireplace into a real heating appliance for your home.
