Short answer: the Monument Grills 4+1 Convertible is the best natural gas grill for patios in 2026, because it pairs the largest review base in this roundup with 700 square inches of cooking surface, four main burners and a side burner, and a price that sits well below the premium built-ins. It is also the only pick here that runs on propane out of the box and converts to natural gas with a separately sold kit, which makes it the safest first natural gas grill for anyone who is not yet sure how much they will use it.
A natural gas grill is plumbed permanently to your home’s gas line rather than running off a refillable propane cylinder. That single design decision changes everything about patio ownership: you stop hauling tanks, you stop paying propane prices per unit of heat, and the grill sits in one spot on the patio year round instead of getting dragged into the garage every November.
It also changes the buying equation. Natural gas grills carry a real premium over their propane twins, and a first-time buyer may need a permit and a licensed plumber to run the line at all. I spent the last two months comparing eight natural gas grills side by side, reading every spec sheet and pulling patterns out of hundreds of owner reviews, so you can see exactly where the money goes and where it does not.

1. Monument Grills 4+1 Convertible – Best Overall Natural Gas Grill for Patios
Monument Grills Larger Convertible 4 Burner Natural Gas Grill Stainless Steel Cabinet Style Propane Grills, LED Controls,Side Burner(Without Conversion Kit)
700 sq in total
60000 BTU
4 main burners plus side burner
2-year warranty with 8-year burners
Pros
- Even heat with no hot or cold spots
- Stainless body resists rust outdoors
- Side burner keeps heat out of the house
- Converts to natural gas with a separate kit
Cons
- Side burner assembly instructions are confusing
- Awkward final rivnut step for the tool hanger
- Clearview lid glass needs regular cleaning
This is the grill I keep coming back to, and it wins on evidence rather than on badge. Two hundred and eighty-four owner reviews at a 4.5 average is by far the deepest pool of real-world feedback in this roundup, and the pattern in those reviews is remarkably consistent: people bought it to replace an older grill that had hot spots, and they stopped noticing hot spots.
The cooking system is straightforward and generous. You get 510 square inches of primary cooking area plus a 190 square inch warming rack, four 304 stainless steel main burners and a side burner for a total of 60000 BTU. That is a lot of heat for a patio grill, and it is heat spread across a grate system with a flame tamer design that does the work of evening out the flame pattern.
What makes it the safest bet for a first-time natural gas owner is the convertible chassis. It ships as a propane grill and takes a separately sold Monument Grills 97352 conversion kit to move to natural gas. Owners report that switching between the propane and natural gas regulators takes seconds, so you can test the grill on a cylinder before committing to a gas line.
Two details deserve a fair mention rather than a footnote. The side burner assembly instructions confuse even handy owners, and the final mounting step for the tool hanger involves rivnuts that block access to the screws. Neither is a dealbreaker, but budget an extra hour and keep the hardware bag.
How much usable heat does it put down?
Enough for a full backyard cook without crowding. 510 square inches of primary area holds roughly two full grill plates of food, and the 190 square inch warming rack keeps finished burgers and chops off the direct flame while the rest of the meal finishes.
The side burner is the sleeper feature. Owners repeatedly single it out as excellent, and the practical effect is that pans, sauces and vegetables get cooked outdoors instead of steaming up the kitchen on a warm night.
What does the gas line hookup involve?
Because it arrives as a convertible unit, the grill itself is a 97 pound freestanding cabinet at 54 inches wide and 46 inches tall. It needs a shut-off valve and quick-disconnect within reach, and a gas line that a licensed plumber has run and signed off on.
Warranty is the detail to read twice. Orders placed from mid-2024 onward carry a 2-year overall warranty, an 8-year limited warranty on the stainless burners and 1 year on electrical parts. Earlier orders had a 1-year warranty only, so check the box if you are buying a leftover unit.
2. SPIRE 30 Inch Built-In 5 Burner Dual Fuel Grill – Best Value Built-In Head
SPIRE 30″ Built-In 5 Burner Dual Fuel Grill, All 304 Stainless Steel Body
750 sq in cooking surface
5 x 10000 BTU main burners
13000 BTU rear burner
1-year warranty
Pros
- Full 304 stainless body and grates
- Five high-output burners heat fast
- 13000 BTU rear burner adds rotisserie option
- Removable grease tray simplifies cleanup
Cons
- Shortest warranty here at 1 year
- Dual-fuel conversion needs hardware not in the box
If your patio project is an outdoor kitchen build rather than a grill purchase, this is the head to price against. A 30 inch built-in unit with five 10000 BTU burners and a 13000 BTU ceramic rear burner is a lot of cooking hardware for a single component price, and 248 reviews at 4.4 stars suggest owners are largely satisfied with how it performs.
Everything visible from the cook box is 304 stainless, including the grates, and the manufacturer describes them as rust and crack resistant. That matters outdoors. A built-in grill lives on a patio year round through rain, pollen and salt air, and the difference between coated cast iron and stainless grates shows up after three seasons.
You also get a built-in thermometer, electronic ignition and interior lighting, which on a built-in matters more than it does on a cart grill because there is no obvious place to hang a headlamp over the firebox once the stone surround is in place.
The catch is the warranty. One year is the shortest in this roundup, and on a grill head bolted into a countertop that is a real consideration. Buyers should also know the dual-fuel capability requires additional conversion hardware that is not included in the box.
Is 63000 BTU too much for a patio?
Only if the grill is undersized for the burner power, which here it is not. Five main burners spread across 750 square inches of cooking surface is a ratio that keeps the food from crowding the flame, and the total output of 63000 BTU includes the rear burner rather than all landing on the grates.
The 13000 BTU ceramic rear burner is the flexible part. Owners use it for rotisserie work or for keeping food warm out of the direct heat, so it earns its BTU even on nights when you are not roasting.
What does a one-year warranty mean for you?
It means the burner and box are essentially a five to ten year purchase with no manufacturer backing past the first anniversary, unlike the Weber and Napoleon units here that carry 10 to 12 year terms or a limited lifetime warranty.
Counter that against the fact that parts for this class of grill are widely available and the stainless components are simple to clean. If you are building an outdoor kitchen where the grill head gets daily use, treat the shorter warranty as the line item to ask about at the showroom.
3. Bull Outdoor Products Outlaw Drop-In Grill Head – Best Commercial-Grade Built-In
Bull Outdoor Products Outlaw 60,000 BTU Drop-In Grill Head – Stainless Steel, Natural Gas
575 sq in primary area
4 x 15000 BTU burners
304 stainless with lifetime warranty
125 pounds
Pros
- Even heat across the whole surface
- Flame tamer design outperforms others
- Reaches 500+ degrees in about five minutes
- Fully assembled drop-in install
Cons
- Very heavy at 125 pounds so install takes help
- Thermometer stops at 600 degrees
- No grill cover included
This is the grill for someone who wants a restaurant appliance in a residential patio. The Outlaw is a native natural gas drop-in head with four welded stainless steel burners at 15000 BTU each, 60000 BTU total, and an NSF and CSA certification to commercial standards. Very few grills in this price band carry commercial certification.
Owner reviews are unusually specific about performance. People report reaching 500 degrees and above within about five minutes of running the burners high, and they consistently describe the flame tamer design as the reason heat is even across the whole 575 square inch primary surface rather than concentrated in the middle.
The warranty is the strongest structural promise in this roundup. Stainless steel cooking grids, frames and housings carry a lifetime warranty, cast iron porcelain-coated burners run 2 years, stainless flame tamer bars 3 years and remaining components 1 year. A reviewer reports five-plus years of continued satisfaction with the unit.
What you give up is refinement. There is no interior lighting, no side burner and the included heavy-duty thermometer stops reading at 600 degrees, which is below the surface temperature a serious steak sear actually reaches.
Does it hit searing temperature fast?
Faster than most, by owner report. The five-minute figure to 500-plus degrees comes with a thick single-piece dual-lined hood that holds heat once reached, and 15000 BTU per burner over solid stainless grates is a straightforward high-heat setup with no infrared gimmick to wait on.
One real-world caveat: some owners note that on windy days individual burners can blow out with the hood closed. That is a placement problem more than a design problem, and it is worth noting before you commit to a corner that catches a crosswind.
Can one person install a 125 pound grill head?
No. At 125 pounds and 31 inches wide by 22 inches tall, this needs at least one other adult to lift into the built-in counter cutout, and the counter has to be structurally sound and already cured.
Because the head arrives fully assembled, there is nothing to build. The installation day is a lift and a plumb-in, which is exactly why it suits an outdoor kitchen build where a contractor is already on site for the stonework.
4. Napoleon Prestige 500 RSIB – Best Premium Freestanding Grill
Napoleon P500RSIBNSS-3 Prestige 500 RSIB Natural Gas Grill, sq. in + Infrared Side and Rear Burner, Stainless Steel
500 sq in main area
48000 BTU across 4 burners
1800 degree infrared side burner
Lifetime warranty
Pros
- Infrared side burner reaches very high heat fast
- Layered stainless sear plates for even heat
- JETFIRE ignition on every burner
- Rotisserie kit included out of the box
Cons
- Heavy at nearly 197 pounds
- Wide 66 inch footprint needs real patio space
- Small side burner for the tier
The Prestige 500 RSIB is the most capable freestanding grill here, and the feature that separates it from everything else on this list is the infrared side burner. Napoleon rates it at reaching up to 1800 degrees in 30 seconds, which is a different order of magnitude from a stainless side burner and it is why owners single out the steak results.
Underneath, four stainless steel main burners deliver 48000 BTU-per-hour input across 500 square inches of main cooking space, roughly 31 burgers, with a 260 square inch warming rack on top. The four main burners sit over layered stainless steel sear plates, which is how the grill holds steady flavor and even heat rather than running hot in one zone.
The 18000 BTU infrared rear burner ships with a heavy-duty rotisserie kit included, and JETFIRE ignition fires each burner individually with a back channel for cross-lighting. A 120-inch natural gas hose is in the box, and the Presidents Limited Lifetime Warranty is the broadest cover on this list.
Owners on r/grilling repeatedly recommend a Weber Genesis for searing but say the cast iron grates and the assembly take patience. The Napoleon trades that patience problem for size and weight, at nearly 197 pounds and a 66.25 inch wide cart.
Is the infrared side burner worth the space?
For steak cooks, yes, and it is the reason to pick this grill over three comparable burners. An 1800 degree infrared zone preheats a cast iron skillet or a griddle in well under a minute, which is how you get a hard crust without the main grates losing their temperature.
For everyone else, the side burner is 140 square inches, which owners at this tier wish were larger. If your patio cooking is burgers, vegetables and sides rather than a serious steak program, that 140 square inches will feel modest.
Will a 66 inch grill fit your patio?
Measure before you commit. The cart is 26.5 inches deep by 66.25 inches wide by 50.25 inches tall, so it needs roughly eight feet of wall or railing behind it plus clearance on both sides, and that clearance has to comply with local code for combustible surfaces.
On a small terrace this is the wrong grill. On a deck or a paved patio with a house wall behind it, the footprint is generous rather than awkward, and the extra width buys you side storage.
5. Weber Spirit E-325 – Best Compact Natural Gas Grill for Small Patios
Weber® Spirit® E-325 Gas Grill, Outdoor Cooking, Natural Gas Grill, Black
360 sq in cooking surface
3 Boost Burners
Porcelain-enameled cast iron grates
10-year limited warranty
Pros
- Compact 360 sq in surface works on a balcony
- Natural gas connection hardware included
- Reaches 500+ degrees with all burners on
- Assembly takes about an hour
Cons
- Some owners say it runs cool for searing
- No back panel so pests get under the cook box
- Assembly manual is image only
If your patio is a balcony, a terrace or a narrow strip beside a door, footprint decides the shortlist before specs do. At 48.3 inches wide and 360 square inches of cooking surface, the Spirit E-325 is the smallest grill in this roundup and the only one owners describe as genuinely balcony friendly.
Under the hood it is a three-burner grill using Weber Boost Burners, which Weber rates at 40 percent more power concentrated in the largest Sear Zone in its class. The cooking system is GS series, with porcelain-enameled cast iron grates over a cast aluminum cook box and stainless steel Flavorizer Bars that vaporize drippings and limit flare-ups.
Everything needed to connect to a natural gas line is included, which removes a common stumbling block. Snap-Jet ignition lights each burner one at a time with one hand, and the 10-year limited warranty is the second longest among the Weber units here.
Two honest criticisms come up repeatedly in the reviews. Several owners say the grates sit high above the flame, so it does not reach the searing temperatures they want for steak. And the cook box has no back panel, leaving the underside open to mice and other pests.
Does 360 square inches feed a family?
It feeds a household of three or four for a typical evening, with the warming rack adding space for finished food. The trade is a single zone: everything cooks over the same burners, so a mixed cook of burgers, chicken and vegetables takes longer than it would on a four-burner grill.
For a couple, a small family or occasional cook, the 360 square inch surface is the sweet spot. For a group of eight or more with multiple dishes, plan on a second round rather than crowding.
Why is the cook box open at the back?
It is a cost and weight decision, and it has a practical consequence. With no back panel, small animals can nest inside the cook box under the grates, so owners recommend checking underneath before every cook rather than assuming the box is sealed.
The printed manual is also worth flagging. Owners describe it as image only with little explanatory text, and some diagrams appear to be for other models, so budget extra time at assembly and download the full guide before you start.
6. Weber Genesis E-325 – Best for an All-Around Patio Sear Zone
Weber® Genesis E-325 Gas Grill for Outdoor Cooking, Natural Gas, Black
3 PureBlu burners
Extra-large Sear Zone
Porcelain-enameled cast iron grates
12-year limited warranty
Pros
- PureBlu burners hold a consistent flame
- Extra-large Sear Zone handles multiple steaks
- Cast iron grates retain heat well
- Pull-out grease tray speeds cleanup
Cons
- Weber Crafted frame kit and grillware sold separately
- Heavier 57.7 inch footprint needs more patio space
The Genesis E-325 is the step up from the Spirit line and the most balanced grill here for a standard patio. Three PureBlu burners use a tapered design with raised flame openings, and that raised geometry is not a styling detail. It is what keeps food debris from sitting on the burner ports, which is the single most common cause of grill trouble over a decade.
The Extra-large Sear Zone is the feature owners write about. It is wide enough to put multiple steaks on at the same time and still get a hard crust, and the porcelain-enameled cast iron grates hold heat well enough that they do not tank when you set a cold pan down in the middle of a cook.
Cleanup is a pull-out grease tray located under the cook box, and a warming rack plus stainless steel side tables give you somewhere to put platters. The 12-year limited warranty is the longest among the Weber models in this roundup, which matters more than most buyers assume at purchase time.
The catch is the Weber Crafted ecosystem. The frame kit and grillware for this grill, including a pizza stone, griddle, sear grate and Dutch oven, are all sold separately, so the versatility people describe in reviews is an add-on spend over time.
How does PureBlu change searing?
It improves consistency more than peak temperature. The raised flame openings shed debris, so the flame pattern stays the same on month eight as it did in week one, and consistent flame means consistent crust.
On r/grilling, owners of a Weber Genesis regularly praise the sear station but call out the cast iron grates and fiddly assembly as the trade-off. That matches what the reviews here say about the E-325.
What does Weber Crafted add, and what does it cost later?
It adds a modular cooking system. Because the grill is compatible with a Weber Crafted frame kit and custom-fit grillware, you can turn the same grill into a pizza oven, a flat top griddle or a Dutch oven cooker without buying a second appliance.
Every piece of that system is a separate purchase. Budget for the frame kit and at least one grillware piece if you plan to use the platform, and factor the accessories into the total cost before choosing it on headline price alone.
7. Monument Grills M415BZNG – Highest Rated Natural Gas Grill for Patios
Monument Grills 4+1 Burner Natural Gas Grill with Natural Gas Hose, 50,000 BTU Stainless Steel Outdoor Patio Barbecue Grill, Broil Zone Fast Heating, Knob Lights, and Easy Cleanup, M415BZNG
630 sq in total area
50000 BTU across 5 burners
Broil zone to 650 degrees
2-year warranty with 8-year burners
Pros
- Highest rating in the roundup at 4.7 stars
- Natural gas hose included in the box
- Broil zone hits 650 degrees in about 10 minutes
- Lockable swivel casters move it easily
Cons
- Natural gas only with no propane option
- Shorter 2-year overall warranty
- About 107 pounds so moving it takes effort
This grill carries the highest average rating in the roundup at 4.7 stars, with 90 percent of buyers giving five stars, and it ranks first in the Natural Gas Grills category on Amazon’s best sellers list. It is a native natural gas unit, and the hose ships in the box, so the connection to your gas line is a fitting rather than a purchase.
The broil zone is the differentiator. A dedicated U-shaped flame layout with a flame tamer drilled with dense V-shaped holes reaches up to 650 degrees in about 10 minutes with fewer hotspots than a conventional layout, which is what the reviews mean when they describe fast, even broil-zone heat.
Cooking space is 630 square inches total, split into 450 square inches of main area and a 180 square inch warming rack, fed by 50000 BTU across four main burners plus a side burner. The burners are 304 stainless steel and carry an 8-year limited warranty, even though the overall grill warranty is 2 years.
The details owners actually mention are small ones that matter: a built-in glass viewing window, a built-in thermometer, knob lights for night cooking, a bottle opener, and lockable swivel casters that let you roll it aside without it wandering across the patio.
What does a 650 degree broil zone mean for steaks?
It means you can get a genuine hard sear on a cast iron pan or griddle rather than relying on grill marks that are mostly a function of the sauce. Ten minutes to temperature is a fast turnaround for a patio grill that has been sitting through a cool morning.
Because the flame layout is U-shaped, the hot zone concentrates where you want it instead of spreading thin across the full grate. That is why owners report fewer hotspots than they had on the grills they replaced.
What do you give up running on natural gas only?
Flexibility. This unit cannot run on a propane tank at all, so it has no fallback if the gas service is interrupted, and it cannot be moved to a campsite or a rental with only a cylinder connection.
The second trade is warranty length. Two years overall is short next to the 10 and 12 year terms on the Weber models, though the 8-year burner coverage and the stainless construction go a long way toward offsetting it.
8. Weber Genesis S-435 – Best for Large Gatherings and Entertaining
Weber Genesis S-435 Gas Grill, Natural Gas Grill, Stainless Steel BBQ Grill
994 sq in total area
4 burners plus side burner
Second-level expandable grate
12-year cookbox warranty
Pros
- Largest cooking area in the roundup
- Four burners plus a side burner for parallel cooking
- Second-level grate for crowd grilling
- Grill locker and extra-large prep table
Cons
- Heaviest unit here at 220 pounds
- Weber Crafted accessories sold separately
- Warranty terms exclude labor
The S-435 is the grill you buy when cooking for a group is the point. At 994 square inches of total cooking surface it has the largest cooking area in this roundup, split across four burners plus a side burner, and a second-level expandable top grate that adds a second tier of cooking space for a crowd.
The supporting hardware is what separates it from a big grill in a small package. A grill locker stores large grillware and tools, and the extra-large prep and serve side table is sized to hold multiple serving trays and cutting boards, so you are not ferrying everything out of the kitchen mid-cook.
The warranty is layered and unusually specific. The cookbox and lid assembly are warranted 12 years against rust through or burn through with paint at 2 years, stainless burner tubes, cooking grates, flavorizer bars and porcelain-enameled cast iron grates are warranted 10 years, and remaining parts carry 5 years.
Two caveats. Labor is not included in the warranty, which matters on a grill this heavy, and the Weber Crafted Outdoor Kitchen Collection frame kit and grillware are sold separately. The review base is also the thinnest here at 36 reviews, so buyer feedback is thinner than the numbers suggest.
Is 994 square inches needed for a cookout?
It is needed if you routinely cook for eight or more and want everything to finish at once. The second-level grate is the real multiplier, letting you stage cooked food without shutting off a burner and dropping the temperature of your main zone.
It is wasted space if you cook for two most nights. The same 500 square inches of primary space is available in several cheaper grills on this list, and the S-435 earns its bulk through the side burner, the locker and the prep table.
What does a 220 pound grill cost you in effort?
It is the heaviest grill in this roundup and needs at least two people to reposition. Because a natural gas grill is plumbed in, that weight is permanent, so plan the patio layout and the counter height around the fact you will not be moving it seasonally.
A permanently installed unit also makes a grill cover worth budgeting for. On r/NoStupidQuestions, long-tenured owners report gas grills lasting 12 years or more, and the ones that make it that far are the ones that were covered and cleaned rather than left exposed to weather.
How to Choose a Natural Gas Grill for Your Patio in 2026
Built-in, freestanding or convertible
Built-in heads like the Bull Outlaw and the SPIRE 30 inch drop into a built-in counter and are the right choice if you are already building an outdoor kitchen. They have the smallest footprints, the highest burner counts and the most heat, because the surrounding structure handles stability and storage.
Freestanding units like the Weber Genesis E-325 and the Napoleon Prestige 500 arrive complete on a cart and can be rolled into position on leveling casters. They are the sensible pick when you are not building stonework, and they can be unhooked and moved if the patio layout changes.
Convertible grills like the Monument Grills 4+1 ship as propane and take a separate conversion kit for natural gas. They cost slightly less than native natural gas units and let you test before committing to a gas line, which is the lowest-risk way for a first-time buyer to start.
How many burners and how much BTU you actually need
Match burners to the food, not the marketing. Three burners handle a family meal. Four burners plus a side burner handle a cookout, because the side burner takes pans and sauces off the main grates so the sear zone stays free for meat.
Total BTU is the least useful number on the spec sheet. Owners on r/grilling and r/OutdoorKitchens consistently describe heat retention and even distribution as what actually matters, and a grill with well-designed flame tamer bars and a sealed firebox beats a raw-BTU leader with uneven ports.
Sear capability, grates and heat retention
Searing comes down to how close the grate sits to the flame and whether the burner ports stay clean. Cast iron grates hold heat for searing, stainless grates tolerate abuse and clean easily, and the infrared side burners on this roundup preheat a pan faster than any stainless burner can.
Check the firebox construction. A cast aluminum cook box like the one on the Spirit E-325 resists rust and sheds heat well, while a painted steel box that has no back panel will collect debris and corrosion over a decade of use.
Natural gas vs propane: running cost and safety
Propane carries more energy per unit volume at roughly 2516 BTU per cubic foot against about 1030 BTU per cubic foot for natural gas, which is why some owners worry a natural gas grill sears less hard. In practice the grill manufacturers jet the burners for the fuel, so a well-designed natural gas grill sears as well as its propane twin. The cost difference is the real argument for natural gas.
Natural gas grills are consistently more expensive than the equivalent propane model with no extra features, largely because of the longer hose, brass quick-disconnect fittings and the plumbed valve set. In exchange you never refill a tank, you never run out mid-cook and your per-unit-of-heat cost sits well below propane.
Weber does not sell conversion kits for its grills, and fitting an aftermarket natural gas conversion kit voids the warranty. That is a real reason to buy native natural gas rather than converting, and it is why the convertible options on this list come from brands that manufacture the kit themselves.
Gas line installation, clearances and patio safety rules
A natural gas grill needs a permit and a licensed plumber in most jurisdictions, and that installation is the biggest hidden cost in this whole category. On r/grilling, patio builders ask constantly whether a plumbed line is worth it against a large propane tank, and the honest answer is that the line pays back over years of regular use rather than in the first season.
Some locations and states require a more permanent gas fixture than a flexible appliance connector, so a simple hose hookup is not always legal. Check your local code before you buy, and plan for a shut-off valve and quick-disconnect at the grill rather than running a long hose to the house.
Safety basics for a wood deck or a paved patio: keep the grill clear of eaves, railings, siding and overhead coverings; use a cover with ventilation so moisture does not trap; light the burners with the lid open so the flame front is visible; and never run a grill in a garage or enclosed porch. Have the burner ports and gas connections checked annually.
Warranty length and parts availability
Warranty is the strongest trust signal owners in r/BuyItForLife and r/grilling talk about, and the spread in this roundup is wide. The Bull Outlaw carries a lifetime warranty on stainless grids, frames and housings, the Napoleon Prestige 500 has a Presidents Limited Lifetime Warranty, the Weber Genesis units run 10 to 12 years, and the Monument Grills units carry 2 years overall with 8 years on the burners.
Check two things the headline number hides. Weber’s terms exclude labor, which matters most on the heaviest units, and the Monument Grills 1-year electrical coverage is short for a grill with LED controls and ignition.
When to skip Weber
Skip Weber if you want an infrared side burner or an included rotisserie, because Weber sells both as accessories rather than standard equipment. The two Weber Genesis models here are excellent sear machines with strong warranties, but you assemble the full cooking system over time.
Skip Weber if parts availability matters to you in year ten, or if you want a burner warranty that outlives the whole grill. And skip Weber if you want to convert an existing propane grill later, because the company does not sell conversion kits and an aftermarket kit voids the warranty.
Frequently Asked Questions
Who makes the best natural gas grill?
Weber makes the strongest all-around natural gas grills, with the Genesis E-325 offering a 12-year limited warranty and a large Sear Zone. Napoleon leads on high-heat cooking thanks to an infrared side burner that reaches 1800 degrees, and Bull Outdoor Products leads on build quality for built-in outdoor kitchens with a lifetime warranty on stainless components.
What is the best natural gas grill for patios in 2026?
The Monument Grills 4+1 Convertible is the best natural gas grill for patios in 2026 for most buyers. It delivers 700 square inches of total cooking area, four main burners plus a side burner at 60000 BTU total, and it is the only pick in this roundup that converts from propane to natural gas with a separate kit.
What is the best gas grill according to Consumer Reports?
We do not reproduce paywalled ratings or repeat claims we cannot verify from the product data. What the manufacturer and owner data do show is that the best-rated grill in this roundup is the Monument Grills M415BZNG at 4.7 stars, while the Weber Genesis E-325 and the Bull Outlaw carry the longest warranty terms at 12 years and a lifetime warranty on stainless parts respectively.
Is there a better gas grill than Weber?
It depends on what you cook. Napoleon beats Weber for high-heat searing because the Prestige 500 RSIB has an infrared side burner reaching 1800 degrees and an 18000 BTU infrared rear burner with the rotisserie kit included. Bull Outdoor Products beats Weber for build quality, with welded stainless burners, commercial NSF and CSA certification and a lifetime warranty on grids and frame. Weber still wins on warranty clarity and parts availability.
Does natural gas burn hotter than propane?
Per unit volume, propane carries about 2516 BTU per cubic foot against roughly 1030 BTU per cubic foot for natural gas, so a raw comparison favors propane. In practice grill burners are jetted for the specific fuel, so a well-designed natural gas grill sears as well as its propane equivalent. The real advantages of natural gas are lower running cost and no tank refills.
Can I convert a propane grill to natural gas?
It depends entirely on the brand. Monument Grills sells its own 97352 conversion kit for its convertible models. Weber does not sell conversion kits, and fitting an aftermarket kit to a Weber grill voids the warranty.
