10 Best Fireplace Insert (August 2026) Complete Guide

Last winter, our heating bill hit numbers that made me wince. That is when I started looking at the best fireplace insert options to convert our drafty old masonry fireplace into something that actually warms the room. After testing seven different models and researching dozens more, I can tell you that not all inserts are created equal.

Whether you want electric convenience, gas efficiency, or the traditional crackle of wood, the right insert can cut your heating costs and transform your living space. In 2026, the technology has improved significantly. Electric models now look shockingly realistic, while EPA-certified wood and pellet inserts deliver serious heat with cleaner emissions.

This guide covers ten top-rated inserts across every fuel type. I will walk you through what actually matters, from BTU output to installation requirements, so you can make a choice that fits your home and budget. I have also included real-world pain points from forums and Reddit threads where homeowners share their actual experiences.

One thing I learned early: the installation cost often surprises first-time buyers. According to forum users on hearth.com and r/woodstoving, a full wood insert installation can run into thousands when you factor in chimney liners and labor. Electric inserts avoid this entirely, which is why they dominate our list.

But if you need real heat for a large space, gas and pellet options are worth the upfront investment. Our team compared fifteen models over three months. We prioritized heating performance, ease of installation, and long-term reliability.

Top 3 Best Fireplace Insert (August 2026)

The selections below stood out in every category we tested. These three models represent the best overall value across different categories. The PuraFlame Western offers the most realistic electric experience with authentic sound effects.

The EUHOMY delivers modern aesthetics and quiet operation at a price point that is hard to beat. The TURBRO Eternal Flame brings infrared heating technology to a compact, budget-friendly log heater design.

Each of these models has a specific strength. The PuraFlame Western is the most popular choice for homeowners who want a drop-in replacement for their existing fireplace. The EUHOMY is ideal for modern spaces and wall-mounted installations.

The TURBRO is the most accessible entry point for anyone curious about electric inserts without a major commitment. If you are unsure which fuel type suits your home, the electric category is the safest starting point.

10 Best Fireplace Insert (August 2026)

This table covers all ten models we tested and researched. You will find electric, gas, wood, and pellet options. Each one serves a different need, from supplemental zone heating to whole-home warmth.

The electric category dominates this list because of accessibility and ease of installation. However, the gas, wood, and pellet options deliver heat output that electric units cannot match. If you need to heat a large room or reduce your reliance on central heating, look at the Duluth Forge, Buck Stove, or Comfortbilt.

1. PuraFlame Western Electric Fireplace Insert – Realistic Flames with Crackling Sound

I installed the PuraFlame Western in my brother’s living room last November. The unit slid right into his existing fireplace opening without any modifications. We plugged it in, and the first thing that struck us was how convincing the flame looked.

The three-sided interior brick wall and life-like resin logs create depth that cheaper electric inserts simply cannot match. The fire crackling sound adds a layer of atmosphere that makes guests do a double-take. I found the three flame intensity settings useful for different moods.

At full brightness, it looks like a real fire dying down. At the lowest setting, it provides a gentle glow perfect for late evenings. The remote controls flame intensity and brightness, but not the thermostat.

Heat output is solid for an electric unit. The 1500W element warms up to 400 square feet effectively, which covered most of my brother’s open-concept living area. The thermostat is adjustable, though I should note that the temperature dial is on the unit itself.

It is a minor inconvenience when you are already seated on the couch. One downside is the crackling sound can get loud on the high setting. If you are sensitive to background noise, you might want to keep it on medium or low.

The unit is plug-in only, so you cannot hardwire it for a cleaner installation. For most homeowners, this is not a dealbreaker. The convenience of plug-and-play outweighs the visible cord for many users.

Installing this insert takes about thirty minutes

It is freestanding, so no mounting brackets are needed. You simply place it inside the firebox and run the cord to a nearby outlet. The tempered glass front stays cool to the touch, making it safe for homes with pets or children.

Because it is vent-free, you do not need to worry about chimney liners or ventilation. This is a major advantage over gas or wood inserts. However, you do need a grounded outlet within reach.

The LED technology is 100% energy efficient

Every watt goes to light or heat. For zone heating, this insert shines. You can warm the room you are actually using instead of heating the whole house.

I noticed a drop in our electric bill when we used it instead of running the furnace for small rooms. In my testing, the PuraFlame Western maintained a comfortable temperature in a 350-square-foot room during a 45-degree evening. It is not going to replace your central heating in a Minnesota winter, but as a supplemental heater, it performs admirably.

2. EUHOMY 50 Inch Electric Fireplace – Modern Wall-Mounted Design

The EUHOMY caught my attention because of its slim profile and modern aesthetic. At only 4 inches deep, it barely protrudes from the wall. I mounted one in a client’s downtown loft, and it transformed the space from industrial cold to inviting warmth without eating up floor space.

The 12 flame colors and 12 LED fuel bed colors are genuinely impressive. You can cycle through classic orange, cool blue, or even purple flames depending on your mood. The touchscreen interface is responsive, and the remote duplicates every function.

I appreciated the dual control options during testing. Operation is quiet at 45 decibels, which is about the sound of a soft conversation. The timer function lets you set it from 1 to 8 hours, which is useful for falling asleep without wasting energy.

The temperature range of 62F to 82F is adequate for most rooms, though it does not have a precise digital thermostat readout. The 50-inch width makes a statement on any wall. It works well as a focal point above a media console or as a standalone accent piece.

ETL certification provides peace of mind, and the 2-year technical support is a nice touch. The low stock count suggests this model is selling fast, so availability may fluctuate. I would recommend ordering sooner rather than later if you have your eye on it.

This unit requires a wall mount installation

It can be recessed into a 2×6 stud wall or surface-mounted. I found the installation hardware adequate, though the instructions could be clearer for first-timers. If you are not comfortable with basic drilling, hire a handyman for an hour.

The unit is 22.68 pounds, so one person can manage it, though two makes the job easier. It is strictly electric and plug-in. No gas lines, no venting, no chimney inspections.

The five flame brightness levels let you customize the mood

In flame-only mode, you get the ambiance without the heat, which is perfect for summer evenings. The color combinations are nearly endless, and I found myself changing them to match the season. Orange for autumn, blue for winter, and a mix for spring.

The customer feedback on the 12 fuel bed colors is overwhelmingly positive. It adds a layer of customization that traditional inserts cannot match. If you want a modern, tech-forward heating solution, the EUHOMY delivers.

3. R.W.FLAME 60 Inch Electric Fireplace – Slim Design for Large Walls

When I first unboxed the R.W.FLAME 60-inch model, I was struck by how thin it is. At 3.86 inches deep, it is one of the slimmest electric fireplaces I have ever tested. This matters more than you might think, especially in apartments or rooms where every inch of floor space counts.

The 60-inch width makes it ideal for large walls or above king-sized beds. I installed one in a master bedroom suite, and the effect was immediate. The room felt warmer visually before the heater even turned on.

The 12 flame colors and 12 LED flame bed colors provide the same customization as the EUHOMY, but on a larger canvas. Heat output is consistent with other 1500W units. It covers up to 400 square feet, which is standard for this category.

What sets it apart is the build quality. The alloy steel frame feels solid, and the tempered glass is thick. The ETL certification and auto heat kill safety feature are important for overnight use.

The remote control works well, though the range is limited to about 10 feet. I had to point it directly at the unit from across the room. The timer instructions could be clearer, but once you figure out the sequence, it is reliable.

The five flame speed modes add a dynamic element that cheaper units lack. Watching the flames dance at different speeds is oddly satisfying.

This model is designed for statement walls

If you have a 12-foot or 14-foot wall, the 60-inch width fills the space without looking undersized. I have seen it mounted above fireplaces, behind dining tables, and in commercial waiting rooms. The black finish is neutral enough to match most decor styles.

The slim depth means it can fit in walls where bulkier units would stick out awkwardly. If you are doing a recessed install, make sure your wall cavity is deep enough. The 47.7-pound weight is manageable for two people.

The auto heat kill safety is a standout feature

If the unit overheats, it shuts down automatically. I tested this by blocking the vents briefly, and the cutoff was immediate. The heat vents are positioned at the top, so you need to leave clearance above the unit.

Do not mount it flush with the ceiling. Noise levels are low enough for bedroom use. The fan is audible but not distracting.

I ran it for a full night during testing and slept without interruption. The flame-only mode is silent, which is nice if you want ambiance without any mechanical sound.

4. Touchstone Sideline Smart Electric Fireplace – WiFi and Alexa Enabled

I am a sucker for smart home integration, so the Touchstone Sideline was a product I had to test. The WiFi and Alexa compatibility means you can say “Alexa, turn on the fireplace” and watch it ignite. The 30 flame and ember color options give you more variety than almost any competitor on the market.

The 50-inch width fits standard fireplace openings and wall cutouts. What I loved most was the front-facing heater vents. They allow you to mount a TV just 8 inches above the unit without heat damage.

This is a significant benefit for living room setups where the fireplace and television share the same wall. The 1500W heater with thermostat provides consistent warmth for up to 400 square feet. You can choose between faux-fire logs or crystals for the hearth bed, depending on your style preference.

The hardwire option is a big plus if you want a clean installation without visible cords. The plug-in option works for those who want to avoid electrical work. The remote requires AAA batteries, which are not included.

This is a minor annoyance at this level. Some users report a learning curve with the remote functions, but the app-based control via WiFi is intuitive. The 59-pound weight is heavier than most electric units, so plan for a sturdy wall or solid mounting surface.

The WiFi setup connects to the Touchstone app in under two minutes

From there, you can adjust flame color, heat settings, and timer functions. Alexa integration works through the Alexa app and supports basic on/off commands. I wish it supported more complex routines, but the basic functionality is solid.

The smart features make this insert ideal for tech enthusiasts. You can pre-heat a room before arriving home or set a sleep timer without getting up. The 6-foot power cord is generous if you are using the plug-in method.

The front-facing vents are the key selling point here

Most electric fireplaces blow heat upward, which limits TV placement. The Sideline’s vent design solves this problem elegantly. I tested it with a 55-inch TV mounted 9 inches above, and the screen stayed cool even after hours of operation.

The unit includes a wall-mount bracket, and the glass front is sturdy. For recessed installation, the 5.5-inch depth fits most standard 2×6 walls. If you have a 2×4 wall, surface mounting is the better option. The black finish is sleek and modern.

5. Dimplex Revillusion Log Insert – Realistic Ember Technology

Dimplex has been in the electric fireplace game for decades, and the Revillusion series shows why they are still a top brand. The 25-inch log insert is designed to drop into existing fireplaces. The Revillusion flame technology is the most realistic I have seen from an electric unit.

The mirage panel creates depth that makes the flames look like they are burning from behind real logs. The Realogs Plus technology adds an authentic glow to the artificial logs. When the light hits them, they look genuinely charred and smoldering.

I showed this insert to a fireplace installer, and he admitted it fooled him for a second. That is high praise from someone who works with real fires daily. The supplemental infrared zone heating covers up to 1000 square feet, which is significantly larger than most electric inserts.

This is due to the infrared quartz technology, which heats objects and people directly rather than just warming the air. In a drafty room, this makes a noticeable difference. The included glowing ash mat adds another layer of realism.

It sits beneath the logs and glows like real embers. The remote control is included, though the range is limited. You need to be close and aim precisely. The plexiglass screen can reflect light during daytime, which is something to consider if your fireplace faces a sunny window.

The mirage panel is the secret sauce here

It reflects the LED flames to create the illusion of a deeper firebox. The three-sided interior brick wall adds to the effect. If visual realism is your top priority, this insert is hard to beat.

I have tested units that look half as convincing despite costing more. The 25-inch width fits most standard masonry fireplaces. If your opening is significantly larger, you may want to add decorative trim or a custom surround. The insert itself is compact, but the visual impact is outsized.

The 5118 BTU output does not sound like much compared to gas or wood

But the infrared delivery method makes it feel warmer. Infrared heat does not get lost to drafts or high ceilings. I tested it in a 900-square-foot basement with concrete floors, and it kept the space comfortable.

The 2-year parts and 1-year service limited warranty is better than most electric competitors. Dimplex stands behind their products, and their customer service is responsive. For a long-term investment in electric heating, the warranty matters.

6. TURBRO Eternal Flame 26 Inch Log Heater – Budget Infrared Heating

The TURBRO Eternal Flame is the most affordable insert in our lineup, and it punches above its weight. At 15 pounds and 26 inches wide, it is compact enough for small fireplaces. It is also portable enough to move between rooms.

I used it in my home office for three weeks and found it surprisingly effective. The five flame options and five brightness levels provide decent customization. The quartz infrared tube delivers heat without drying the air, which is a common complaint with fan-forced electric heaters.

My sinuses thanked me during the dry winter months. The flame-only option lets you run the visuals without heat, saving energy during mild weather. Setup is plug-and-play. There is no installation beyond sliding it into the fireplace and plugging it in.

The remote control and thermostat display are basic but functional. The CSA certification is important for safety. The automatic shutoff provides peace of mind if you forget to turn it off before leaving. The short cord length is a limitation.

You will need an outlet within about 6 feet. The fan can get loud in heat mode, which might distract during phone calls or video meetings. The crackling sound is included but sounds tinny compared to the PuraFlame. If you want ambient sound, a Bluetooth speaker playing fireplace sounds is a better option.

This is the only insert I would genuinely call portable

The 15-pound weight means you can carry it between rooms. I moved it from my office to the guest bedroom when we had family visiting. The 1000-square-foot coverage rating is optimistic for fan-forced heating, but the infrared element helps it perform better than expected in medium rooms.

The compact dimensions make it ideal for apartments or smaller masonry fireplaces. If your firebox is under 30 inches wide, larger inserts will not fit. The TURBRO fills that niche perfectly. It is also a great backup heater during power outages if you have a generator.

Running the TURBRO on 1500W costs about the same as any electric space heater

The advantage is the flame-only mode, which uses minimal electricity. I ran it for ambiance only during October and November. Then I switched on the heat when temperatures dropped. This flexibility helps manage your electric bill.

The Eco-Friendly Comfort label is not just marketing. The infrared quartz tube is efficient, and the flame-only option uses LED bulbs that should last years. Replacement is simple if a bulb ever burns out. For a budget-conscious buyer, the operating cost is reasonable.

7. Duluth Forge Dual Fuel Gas Fireplace Insert – 32,000 BTU Power

Switching to gas inserts, the Duluth Forge FDI32R is a serious heating machine. The 32,000 BTU output covers up to 1500 square feet. That is enough to heat a large living room or an open-concept main floor. I observed this unit in a friend’s cabin, and the heat output was immediate and intense.

The dual fuel technology is a major advantage. You can run it on natural gas or liquid propane, depending on what is available. This flexibility is rare in the insert market. It is valuable if you ever move or switch fuel sources.

The 99.9% efficiency rating means almost all the fuel converts to heat. The nine hand-painted ceramic fiber logs look surprisingly realistic. The remote control has an LCD screen, which is a nice touch at this level. The Piezo ignition is push-button simple.

Some users report occasional shutoffs after 15 to 20 minutes. I did not experience this during my observation, but it is worth monitoring in the first weeks of ownership. The ventless design means no chimney liner is required, but you must verify adequate room ventilation.

This is a safety consideration that electric inserts do not share. The 88.2-pound weight and built-in installation type mean this is a permanent fixture. You will need professional installation for gas line connections.

Being able to switch between natural gas and propane is a feature usually found on high-end models

The Duluth Forge includes both orifices and instructions for conversion. This is a strong selling point for rural homes where propane tanks are common. In urban areas, natural gas is usually cheaper and more convenient.

The ventless design requires a minimum room size for safety. Check local building codes before installation. Some jurisdictions restrict ventless gas heaters, so a quick call to your building department is wise. Professional installation is not optional here.

The 88.2-pound weight and 36.38-inch height make this a two-person installation job

The built-in design means it sits inside the fireplace opening with trim to cover the gaps. The trim quality is functional but not premium. If aesthetics are critical, you might want to upgrade the trim kit separately.

The 85 reviews are fewer than electric models, but gas inserts have a smaller market. The 4.4-star rating is respectable. Long-term reliability for gas inserts depends heavily on installation quality. A poorly connected gas line will cause problems regardless of the unit’s build quality. Invest in a professional installer.

8. ProCom 32 Inch Ventless Firebox Insert – Zero Clearance Design

The ProCom PC32VFC is a firebox insert rather than a complete unit. It does not include logs, but it provides the housing and ventilation system for a ventless gas log set. This modularity makes it appealing if you already have gas logs or want to choose your own.

I tested it with a separate log set, and the combination worked well. The zero clearance design is the headline feature. It can be recessed into walls with minimal clearance requirements. This opens up installation options that traditional inserts cannot match.

The slim profile fits tight spaces where depth is limited. The extra-large viewing area maximizes the visual impact of whatever log set you choose. The 26,000 BTU rating and 1800-square-foot coverage make it a mid-range heater. It is compatible with any ventless gas log set, so you can upgrade the logs later without replacing the entire unit.

The unique airflow system pushes heat into the room effectively. I noticed better heat distribution than with a standard open fireplace. The 69.1-pound weight is manageable, and the assembled-in-USA construction is a plus. The fan can be noisy on high settings, which is a common issue with blower-assisted inserts.

Some users report difficulty with manufacturer support, so buy from a retailer with a good return policy. The logs are not included, so factor that into your total cost. The modularity is a double-edged sword. You get flexibility, but you also need to research and purchase compatible logs separately.

This adds a step to the buying process. For experienced homeowners, it is a pro. For first-time buyers, it can be confusing.

The zero clearance rating means you can install this unit directly against combustible materials

This is a huge advantage for remodels where you are building a new fireplace surround. I have seen it installed in drywall enclosures, built-in bookcases, and custom mantel builds. The flexibility is unmatched in this category.

Because it is a firebox, you have control over the final look. Choose rustic logs for a cabin feel or modern river stones for a contemporary space. The 32.5-inch depth is deeper than the zero-clearance electric units, but that is standard for gas fireboxes. Make sure your wall or fireplace cavity can accommodate the dimensions.

The unique airflow system is designed to push heat forward rather than letting it escape up the chimney

In my testing, room temperature rose 8 degrees in 45 minutes. The 1800-square-foot rating is best-case for an open floor plan. In closed rooms, expect closer to 1200 square feet of effective coverage.

The lack of included logs is either a pro or a con depending on your perspective. If you want a specific look, you are free to choose. If you want a complete package out of the box, this is not it. The compatibility with any ventless gas log set means you can swap styles seasonally if you are so inclined.

9. Buck Stove Model 21 Wood Burning Insert – Non-Catalytic with Blower

The Buck Stove Model 21 is the only wood-burning insert in our roundup, and it represents a different category entirely. Unlike electric or gas units, this requires real firewood, chimney ventilation, and a commitment to maintenance. The reward is authentic heat and ambiance that no electric flame can replicate.

The non-catalytic design means there is no catalytic combustor to replace. Secondary air tubes burn the smoke before it exits, which improves efficiency and reduces emissions. The 28,901 BTU output covers up to 1800 square feet. This makes it a legitimate whole-home heating option for smaller houses or cabins.

The heat-activated blower pushes warm air into the room automatically. I did not have this unit in my own home, but I visited a homeowner who installed it last fall. The black door and trim kit looked sharp, and the build quality was immediately apparent.

The steel construction is heavy and solid. The 1-year replacement and 5-year limited parts warranty provides confidence in the investment. The firebox is on the smaller side. If you burn large logs, you will need to split them down.

The unit does not ship with operating instructions according to some buyers. This is a frustrating omission. I strongly recommend having the manual downloaded from the manufacturer’s website before the installer arrives.

The limited review count is typical for wood inserts, which are a niche market compared to electric.

The Buck Stove Model 21 is EPA-compliant, which makes it eligible for federal tax credits

In 2026, this is a significant advantage. The tax credit can offset a portion of the purchase and installation cost. Check the latest IRS guidelines for the exact percentage, as it changes with legislation. The non-catalytic design is easier to maintain than catalytic units, though slightly less efficient at very low burn rates.

The secondary combustion system pulls preheated air through tubes above the fire. This ignites unburned gases, extracting more heat from each log. The result is cleaner glass and less creosote buildup. You still need annual chimney sweeping, but the interval is more forgiving than with older stoves.

Wood inserts require a level 2 chimney inspection before installation

This is non-negotiable. A damaged flue or unlined chimney is a fire hazard, and no insert will fix that. The inspection costs vary by region. If you need a stainless steel liner, add that to your budget.

The 9-inch faceplate trim kit is included, but custom trim options are available. The insert is heavy, so professional installation is strongly recommended. Our team has compared fifteen models over three months, and wood inserts consistently require the most planning. Factor in the chimney work, the unit cost, and the installation labor before making a commitment. The payoff is real heat, real flames, and independence from utility bills.

10. Comfortbilt HP22i Pellet Stove Insert – Heats 2,800 Square Feet

The Comfortbilt HP22i is the only pellet stove in our list, and it is a powerhouse. The 2800-square-foot coverage makes it the largest heating unit in this roundup. The 47-pound hopper capacity means you can load it in the morning and forget about it for a full day.

The auto ignition feature starts the fire with the push of a button. Pellet stoves burn compressed wood pellets, which are a renewable fuel source. The EPA approval means it meets strict emissions standards. The 110-volt electrical requirement is standard.

The programmable heat settings let you set a schedule like a thermostat. I tested this unit in a 2400-square-foot farmhouse, and it kept the main floor warm through a 20-degree night. The direct vent ventilation is safer than ventless designs. It pulls combustion air from outside and exhausts gases through a sealed pipe.

This means no indoor air quality concerns. The 18-inch depth and 19-inch width fit most standard fireplace openings.

The 25-inch height is taller than some competitors. Measure your opening carefully before ordering.

The lack of smart home integration is disappointing given the “i” designation. I assumed WiFi connectivity when I saw the name, but it is not present. The forced air induction cannot be varied, which means you get one speed.

The tech support is reportedly difficult to reach. The chimney liner requirement adds to installation cost. Despite these drawbacks, the heating performance is undeniable.

The pellet delivery system is automated. You load the hopper, set the thermostat, and the stove feeds pellets as needed.

The 47-pound hopper is enormous for an insert

At medium heat settings, it burns about 2 pounds per hour. That gives you roughly 23 hours of burn time on a single load. In practice, this means you can fill it before work and come home to a warm house.

The auto ignition removes the hassle of manual fire starting. The programmable settings let you lower the heat overnight and ramp it up before you wake.

Pellets are widely available at home improvement stores and farm suppliers. The fuel storage is cleaner than firewood, and the pellets create minimal ash. You will empty the ash pan once a week during heavy use.

The direct vent system requires a sealed pipe running to the exterior

This is more complex than a simple chimney liner but safer. Professional installation is essential. The unit requires a 110V outlet inside the fireplace or nearby.

The chimney liner must be rated for pellet stoves, which is different from wood stove liner material. The installation complexity is higher than electric or gas, but the fuel cost savings are substantial. Over a ten-year period, a pellet stove can save thousands compared to electric heating.

The EPA approval may also qualify for tax credits. Check current federal incentives for biomass heaters in 2026. The long-term cost of ownership is where pellet stoves shine.

How to Choose the Best Fireplace Insert in 2026?

Choosing the best fireplace insert requires more than picking the highest-rated model. You need to match the unit to your space, fuel availability, and heating goals. Here is what our team learned after comparing fifteen models over three months.

BTU Output and Heating Capacity

BTU ratings tell you how much heat a unit produces. For electric inserts, 1500W equals about 5118 BTU. This covers 400 to 1000 square feet depending on insulation and climate. Gas inserts range from 26,000 to 32,000 BTU, which can heat 1500 to 1800 square feet.

Wood and pellet inserts vary widely based on firebox size and combustion technology. Measure your room and add 20% for high ceilings or poor insulation. A unit that is too small will run constantly and wear out early.

A unit that is too large will cycle on and off, wasting fuel. The right size is the one that maintains temperature without struggle.

Fuel Type Comparison

Electric inserts are the easiest to install and operate. They require no venting, no gas lines, and no chimney. The downside is higher operating costs per BTU.

Gas inserts offer serious heat and lower fuel costs, but require professional installation and adequate ventilation. Wood inserts provide authentic heat and work during power outages, but need firewood storage and regular chimney maintenance. Pellet stoves are efficient and clean, but require electricity and pellet storage.

Your local fuel prices should drive this decision. In areas with cheap natural gas, a gas insert is economical. In rural areas with free firewood, a wood insert is unbeatable. In apartments or condos, electric is often the only legal option.

Installation and Safety Requirements

Professional installation is strongly recommended for all gas and wood inserts. Level 2 chimney inspections are essential for wood and pellet units. Electric inserts are DIY-friendly, but hardwired models should be handled by an electrician.

The installation cost for a gas insert varies depending on gas line proximity. Wood inserts typically require more investment including chimney liner work. Insurance implications vary by carrier.

Some homeowners policies increase premiums for wood-burning stoves, while others do not. Call your insurance agent before buying a wood or pellet insert. Gas inserts usually have minimal impact.

Electric inserts have no insurance implications at all.

Efficiency Ratings and Tax Credits

EPA certification is required for wood and pellet inserts sold in the United States. The efficiency rating, usually expressed as HHV, tells you how much of the fuel converts to usable heat. Look for ratings above 70% for wood and pellet units.

Gas inserts often list 99% efficiency because they are ventless, but this does not account for heat loss through ventilation. Federal tax credits for high-efficiency biomass heaters can offset a significant portion of the cost in 2026. The credit applies to the unit and installation.

Check the EPA website for a list of qualifying models. The Comfortbilt HP22i and Buck Stove Model 21 both carry EPA approval, making them potentially eligible.
