Check Price on Amazon

The Peterson Real Fyre G46 set is the gold standard for vented gas log realism. The ANSI-certified dual-flame burner produces a layered fire with a tall front flame and a broad, wrapping rear flame that engulfs the steel-reinforced ceramic logs. The hand-painted split oak texture is dense with bark detail, and the glowing ember bed with silica sand muffles the gas flow for a quieter burn.

At 55,000 BTU, this unit heats a large living area effectively. The variable-flame remote allows precise adjustment from a low flicker to a roaring blaze, and the auto-safety pilot valve shuts off the gas if the pilot goes out. Buyers report that the logs look disturbingly real—guests often don’t realize it’s gas until they look closely. The minimum fireplace opening for centering is 30 inches wide at the front and 17 inches tall, so measure carefully.

The weak point is that the remote system requires the pilot to be lit constantly, which consumes a small amount of gas. A few owners noted the burner can develop a defective thermocouple, but vendor customer service (Mr Patio) resolved those issues quickly with replacement parts. For a top-tier, lifelike flame with maximum heat output, this is the set to beat.

This is a vent-free log set, but it earns its place here for its charred split-oak aesthetics and the robust G10 burner that delivers 19,000 to 37,000 BTU. The logs are hand-painted with a charred texture that mimics aged firewood, and the ANSI-certified burner includes an oxygen-depletion sensor (ODS) for safe indoor operation. The variable-flame remote lets you dial in the heat without standing up.

The complete kit includes glowing embers, Bryte Coals, lava granules, a flexible gas line, and a damper clamp for vented use if you choose. Owners report a big, realistic flame that produces zero soot and no odor when properly installed. The set fits a minimum firebox of 34 inches front width and 14 inches depth, making it suitable for both standard and deep hearths.

Some buyers wish the maximum flame height was a bit taller—the G10 burner is great for even heating but lacks the dramatic vertical leap of a dual-flame burner. Also, the pilot flame is a bit loud for a few seconds after shutting down. For those who want a beautiful charred log look with safe, vent-free operation, this set delivers.

The Rinnai EX38DTWN is not a log set—it’s a direct-vent wall furnace that acts as a primary heating source. With a 38,400 BTU modulating burner, it uses forced air to heat up to 1,600 sq ft. The modulating technology adjusts the flame size to match the room’s heat loss, maintaining a consistent temperature without short cycling. The cool-to-the-touch cabinet and self-diagnostic electronics make it family-safe and easy to troubleshoot.

Installation involves cutting a hole in an exterior wall for the concentric vent, but owners report it’s manageable for a moderate DIYer. The built-in programmable thermostat and Wi-Fi connectivity allow you to control the temperature from your phone. In real-world use, homeowners say it heats a 1,200 sq ft house from 10°F to comfortable in under 15 minutes, and the forced-air fan distributes heat evenly without cold spots.

The main drawbacks: the thermostat cannot be set below 60°F, which may be inconvenient for a workshop or garage where you want a lower temperature. It also requires a 120V electrical connection for the fan and electronics. For whole-home supplemental heating, this Rinnai is the most efficient choice.

The Empire DVD36FP30N is a 36-inch direct-vent firebox—the building block for a custom fireplace installation. It runs on a millivolt system, meaning it requires no household electricity to operate the gas valve. The contour burner produces a clean, yellow flame, and the 20,000 BTU output is ideal for a 260 sq ft room or as a zone heater in a larger space.

The firebox ships with a solid glass front and requires the purchase of a barrier screen or door set separately. It does not include a mantle, brick liner, vent pipes, gas hose, or blower, so you have full control over the aesthetics. Owners have used this as a base for custom stone surrounds and built-in cabinetry. A powered blower can be added later to improve heat circulation.

The most common complaint is that at the default setting, the flame is more blue than yellow—some users found the fire less visually satisfying than dual-flame units. The finish on the glass panel can also have minor powder-coating defects. If you plan to build a custom fireplace from the ground up, this is a solid, code-ready foundation, but budget for the extra components.

The DFS-400R-2AC is a stand-alone ventless fireplace with a furniture-grade oak mantel, making it a drop-in solution for rooms without an existing fireplace cavity. The dual-fuel burner accepts either natural gas or liquid propane, and the 32,000 BTU output covers up to 1,500 sq ft. The remote control offers both manual and thermostat modes.

The mantel comes in an Auburn Cherry finish with double doors and a sprayed brick liner that adds a traditional hearth look. Owners who installed it in their living rooms report that it heats a 675 sq ft area easily, even with wood floors. The piezo ignition starts the pilot with a single push, and the battery-powered remote means no electrical outlet is needed near the unit.

Reliability is a mixed bag. Some units have developed pilot issues after a few months—the flame shuts off after 5-10 minutes and the company’s warranty service is reportedly difficult to navigate. The unit is heavy at 88 pounds and requires two people to move. When it works, it delivers great heat and a handsome appearance; the defect rate is higher than average.

The Comfort Glow Montreal is a complete ventless fireplace system with a Pewter Oak mantel that brings a rich, furniture-like aesthetic to the room. The burner outputs 33,000 BTU, enough to heat up to 1,200 sq ft, and the dual-fuel design lets you switch between natural gas and liquid propane. The remote control conceals inside a discreet compartment in the mantel.

Assembly is straightforward—the mantel comes in several panels that bolt together. Buyers note the unit is sturdy and well-built. In use, the flame is adjustable from a low simmer to a full gas-powered blaze. The unit runs without electricity, making it a good backup heat source during power outages. An optional blower (sold separately) improves heat distribution.

The thermostat remote can be slightly confusing to program; some owners never fully figured out the mode switching. The fireplace is ventless, so the flame is shorter than a vented unit, but the heat output is genuine. For someone who wants a pre-built hearth solution for a large room at a reasonable price, this is a strong contender.

The Real Fyre Split Oak Designer Plus is a match-light log set that produces a staggering 90,000 BTU. This is not a unit for a small bedroom—it’s designed for large, open fireplaces where raw heat output matters. The G45 dual-pipe burner creates a front flame that wraps over the ceramic logs, with a deep ember glow that mimics a wood fire’s coal bed.

The hand-painted refractory logs are steel-reinforced for durability. The kit includes a custom grate, glowing embers, sand, connector, clips, and damper clamp. Since it’s match-light, you operate the flame via your existing wall-mounted gas key. No remote or safety pilot is included, but you can purchase those kits separately.

Owners love the realism and sheer heat output. Many replaced wood-burning fireplaces with this set and reported that the logs look extremely convincing, especially with a Bluetooth speaker playing crackling fire sounds. The downside: the logs are heavy (78 pounds) and can arrive broken if the packaging is mishandled. A few buyers received broken logs and had to work with the seller for replacements. Worth it if you want high heat and don’t mind using a wall key for control.

This is the same Peterson Big-Stack log design as the top pick, but paired with the G45 dual-flame burner and the SPK-26 auto-safety pilot valve. The G45 burner still delivers a rich front flame and ember glow, but the control is a basic on/off safety pilot rather than a variable-flame remote. You light it with a piezo igniter or a long lighter, and the flame is adjusted manually at the valve.

The log set includes six hand-crafted ceramic logs, a custom grate, glowing embers, silica sand, a damper clamp, and a flexible gas-line connection kit. It operates on natural gas only. The 55,000 BTU output is substantial for a 24-inch set, providing strong radiant heat once the logs warm up. Owners consistently praise the realistic look and the solid construction.

The primary limitation is the lack of a variable flame control. You get a single flame height, which some users find either too tall or too low for their preference. The SPK-26 valve is not safety-pilot certified for all jurisdictions, so check local codes. For a straightforward, durable log set with excellent aesthetics, this is a great middle-tier option.

The Empire DV-215-SGLP is a compact direct-vent wall furnace designed for off-grid use or as backup heat in a small room. At 15,000 BTU, it’s intended for spaces like bedrooms, studies, or small cabins. It runs entirely on propane with no electricity required—the millivolt system uses the pilot flame to generate enough voltage to open the gas valve. The beige, textured cabinet blends into most walls.

Installation requires mounting on an exterior wall with a direct vent opening. The furnace comes with a piezo ignition, but some users note it’s easier to light with a long lighter. An optional blower (sold separately) can help circulate the heat. Owners who replaced 20+ year old units found the new version performed significantly better, heating an entire small house effectively.

The reliability record is mixed. A few owners had the gas valve stick after a few months of limited use, requiring repeated banging to engage. The manufacturer’s warranty support is non-existent for direct consumers, so you rely on the seller or an authorized dealer. It’s a solid product when it works, but the quality control on the valve assembly is suspect.

The Empire DV215SGXLP is essentially the same core unit as the DV-215-SGLP but sold under a different SKU as a furnace-only package (no thermostat). It’s a 15,000 BTU direct-vent propane wall furnace with a cast iron burner and piezo ignition. The unit is designed for small rooms and off-grid applications, using the millivolt system to operate without external power.

The unit is slim—9.5 inches deep, 20.25 inches wide, and 25 inches tall—fitting into tight spaces. The beige painted cabinet is utilitarian but not unattractive. Owners who installed it in ice fishing shacks and small cabins report that it heats effectively. The unit requires a minimum wall depth of 4.5 inches for venting and a 6.25-inch diameter vent hole.

Several owners reported the same gas valve sticking issue as the sibling model, with the pilot light refusing to stay lit. The manufacturer’s support is absent for direct buyers, so warranty claims must go through an authorized dealer. That said, many units work perfectly for years. For a budget-friendly propane wall furnace, this is the entry point, but be ready to deal with potential valve issues.

The Duluth Forge FDI32R is a ventless gas fireplace insert designed to be fitted into an existing wood-burning fireplace opening. The 32,000 BTU burner runs on either natural gas or liquid propane, and the 99.9% efficiency means almost all the heat stays in the room. The remote control with LCD screen allows you to turn the unit on/off and adjust the flame.

The nine hand-painted ceramic logs sit on an iron grate inside a polished black housing. The insert measures 33.27 inches wide, 18.38 inches deep, and 36.38 inches tall, so it fits into standard fireplace openings. Owners who installed it in their living rooms report that it looks stunning and can heat the entire house. The piezo push-button ignition is simple to use.

Some buyers found the installation more difficult than expected, especially if the existing fireplace opening had unusual dimensions. A few units arrived with cosmetic imperfections or minor damage. The ventless design means the flame is shorter than a vented unit, and some users miss the taller fire effect. For a plug-and-play ventless insert that delivers serious heat, this is a solid option.

The Country Living Glenbrook is an electric fireplace mantel package designed to provide a decorative focal point without the need for gas or venting. The cast stone river rock surround and oak mantel shelf create a rustic, organic look. The 28-inch electric firebox produces up to 1500W (about 5,000 BTU) of supplemental heat for a 400 sq ft room.

It features smart digital control via the Tuya Smart App or Alexa, allowing you to set a timer, adjust flame brightness, and control the heater remotely. The flame effect uses resin logs with a glowing ember ashbed—realistic enough for ambient use, but it does not produce a real flame. The mantel shelf can hold TVs up to about 50 inches.

The unit is very heavy (181 pounds) and the assembly requires at least two people. Some owners felt the faux rock finish looks a bit plastic from up close. The fan noise from the heater is noticeable. This is not a vented gas fireplace, but for a decorative mantel with supplemental heat and smart features, it’s a complete package that matches the aesthetic of real stone.

The LegendFlame 72-inch is a smart electric fireplace insert that can be wall-mounted or recessed into a wall cavity. It features a dual-color flame system that combines an orange main flame with 8 other accent colors, plus 8 colors for the fuel bed. The flame effects are independent from the heater, so you can enjoy the visual when it’s warm outside.

The 1500W heater (5,000 BTU) provides supplemental heat for up to 500 sq ft. It works with Alexa and Google Assistant through the Tuya app, and the remote controls the flame brightness, crackling sound, and thermostat. The unit is CSA certified and built to last. Owners with 2000+ sq ft homes report that it helps maintain a comfortable temperature when run continuously.

The design is modern and minimalist, with a slim 7.8-inch depth that looks flush when recessed. The included logs, crystals, glass chips, and pumice give you options to customize the fuel bed aesthetic. The only downsides are that the fake wood/rocks are difficult to position behind the glass, and the unit is an electric fireplace, not a real flame gas unit. For a smart, versatile electric insert with stunning light effects, it’s a standout.
