The best natural gas patio heaters for restaurant patios are hard-piped radiant units that warm guests and tables directly instead of heating the air around them. Our top pick, the Golden Flame XL-Series at 45000 BTU, is the easiest one to justify on a busy patio, while the Bromic Platinum is the strongest choice when you have a covered structure to hang from.

Outdoor seating is not decoration. For a lot of operators it is a large share of nightly covers, and an unheated patio in October is a patio full of empty tables while the dining room seats the same guests indoors. Heating changes the math: a patio that reliably holds guests through a cold month becomes usable square footage you already pay rent on.
We spent weeks going through the natural gas patio heater options an operator can actually install on a commercial patio, weighing output, mounting options, clearance requirements, and what the real running cost looks like after the gas line is in. The nine units below cover everything from a 40000 BTU bistro tower to an 80000 BTU ceramic burner for enclosed zones.
If you are still deciding on heater class rather than a specific model, our infrared patio heater guide covers the residential and light-commercial side of the market, and this roundup stays focused on hard-piped natural gas for restaurant service. We updated every pick for 2026.

1. Golden Flame XL-Series: The Best All-Around Natural Gas Patio Heater
Golden Flame XL-Series Natural Gas Patio Heater, 45,000 BTU, 89″ Tall, Push-Button Ignition, Anti-Tilt Safety, Wheels, Hammered Silver/Pewter
45000 BTU
15 ft diameter
89 in tall
Natural gas
Variable heat
Pros
- 45000 BTU warms a 15 foot diameter zone
- Push-button spark ignition with pilotless burner
- Variable heat control from low to high
- Sand-fillable base and two wheels for daily repositioning
- Connects to a standard 6 ft natural gas hose
Cons
- Gas hose extension sold separately
- 89 in tower stands tall next to low cocktail tables
- 1-year limited warranty
My first stop when I spec heaters for a patio was always a mushroom-style tower, and the XL-Series is the one I keep coming back to. It throws 45000 BTU across a 15-foot diameter, which is roughly a 175 square foot circle of comfortable radiant heat when it is mounted on a post or weighted base at table height.
What sold me for commercial use is the variable heat control. Guests arrive at different times and the wind picks up after dark, so a single on/off burner leaves you either overheating the early tables or underheating the late ones. Running the burner low at 5 pm and pushing it up at 7 pm solves that without a second unit.
The push-button rapid spark ignition with a pilotless burner removes the lighters and the standing pilot that service staff fiddle with. Battery start means a power outage at the patio does not lock you out of your own heater, which matters more than it sounds on a Friday night.
The sand-fillable base with a hidden ballast cavity is the detail most residential roundups skip. Sand or pavers in that cavity stop a wheeled 45000 BTU tower from being nudged into a dining room when a server backs into it, and the anti-tilt shutoff cuts the burner if it does go over.
Owner feedback is consistent about build quality and heat output, and several buyers call out the natural gas convenience directly. The recurring complaint is the same one we saw: the 6 ft pre-installed hose rarely reaches the gas riser, so plan on a separate extension hose and quick-disconnect fitting in your install budget.
One caution for operators: the listed warranty is 1 year limited, and the listing does not spell out who pays labor. Ask the manufacturer in writing before you buy if you expect to run this nightly for several seasons.
How it performs on a real restaurant patio
On a standard covered patio with 8 to 10 two-top tables, one XL-Series per 4 to 5 tables keeps the seating zone warm and leaves the walkways cool. The radiant pattern means a guest sitting two tables over feels the edge of it, not the center.
Because it runs on variable heat, most operators end up with two XL-Series units on a mid-size patio rather than one oversized unit. Matching units also let you zone the patio, heating the bar end first when the wind comes in from that direction.
Where it falls short
At 89 inches tall, the tower is taller than a standard bistro table and taller than most patio umbrellas when they are opened. If your seating has low-profile furniture or a municipal outdoor dining program that caps heater height, this tower can fail a code check even though the heater itself is fine.
It is also a floor unit. On a rooftop deck or a tightly packed terrace, a floor tower competes with servers and guests for circulation space, and a wall or hanging model is usually the better answer.
2. Golden Flame Resort Model: Best When Ambience Is Part of the Job
Golden Flame Resort Model 49,000 BTU NATURAL GAS Glass-Tube Flame Patio Heater in Rich-Mocha Matte Finish with Mobility Wheels and Protective Cover
49000 BTU
Glass-tube flame
88 in tall
Cover included
Wheels
Pros
- One-piece quartz glass tube gives a full-length visible flame
- Rapid-spark electronic pilotless ignition
- Adjustable flame height from glow to full
- Zippered all-weather cover is included
- Mobility wheels let staff roll it between zones
Cons
- Glass tube needs careful handling during transport
- Natural gas connection still needs a permit in most cities
- 1-year limited warranty
The Resort model is the same heater logic as the XL-Series with a different conversation piece. Instead of hiding the flame behind a perforated screen, it exposes a single quartz glass tube so you see a full-length flame from base to reflector. On a hotel terrace or a restaurant with a design-forward buildout, that visible glow is the difference between equipment and ambiance.
More Top Picks Best Pull Up Bar
Output is 49000 BTU with adjustable flame height from a low Romantic-Glo to a full Lava-Flo. That adjustment matters more than the raw number on a patio that gets used from afternoon drinks through a late dinner service.
Two build details set it apart. The one-piece quartz tube replaces the two-piece center-connector design used on older versions, which removes the single most common failure point in glass-tube heaters. The infrared radiant emitter screen above the tube widens the heat pattern so the 15-foot style coverage does not collapse into a narrow band.
Buyer feedback is warm on the aesthetics, the ignition, and the fact that a zippered all-weather cover is in the box. Commercial operators usually buy covers by the dozen anyway, so having one included saves a trip, but plan on a dedicated cover for any unit that sits through the winter outdoors.
What it is like on service
The included cover and the mobility wheels make this the easiest unit here to store seasonally. Staff can roll it to a storage room between seasons instead of leaving it bolted to a post all year, which cuts down on corrosion and stops it from being a wind catch.
The listing notes outdoor use only with minimum clearance of 36 inches above and 24 inches to the sides. Those are tighter than the ceiling-mounted units in this roundup, which makes placement around umbrellas and awnings easier, but they are not a substitute for the manufacturer installation manual.
Where it falls short
Glass is glass. The tube has to be handled carefully in storage and transport, and a cracked tube is a replacement part and a service call. Operators in high-wind locations or near waterfronts should think hard about whether a visible flame tube survives the season.
The 1-year limited warranty is also short for a unit expected to run nightly, and the listing does not clarify labor coverage. On a commercial install, budget for parts availability rather than assuming a full replacement is covered.

3. Bromic Platinum Smart Heat: The Best Premium Wall and Ceiling Heater
Bromic Platinum Smart Heat 11000W Gas Patio Heater – Natural Gas (NG), 500 Series, 110V, Black Finish – BH0110003-1
39800 BTU
215 sq ft coverage
Wall or ceiling
110V 2A
Tinted ceramic glass
Pros
- Tinted ceramic glass fascia spreads heat evenly and cuts light spill
- Adjustable directional bracket aims heat at tables
- Compact 15.6 in deep body clears tight beams
- Runs on 110V at about 2A for smart controls
- Stainless steel construction
Cons
- Needs 96 in clearance and professional mounting
- Remote control is not included
- Wind noticeably reduces throw distance
The Bromic Platinum is the heater I recommend the moment a patio has a real structure to attach to. At 39800 BTU it is rated for 215 square feet of coverage, which per the manufacturer guidance needs mounting at a minimum of 96 inches clear to walls and ceilings. That mounting height is the whole point: heat comes down along a defined cone onto the table instead of radiating out into a cold night sky.
For an operator, that geometry is the return on investment. A mushroom tower throws a good share of its energy outward and upward, so you are paying to heat the night air. A directional unit mounted over the seating throws heat where the covers are.
The tinted ceramic glass fascia is the reason this unit looks like a flat-screen television when it is off, and the reason light spill is low when it is on. Guest-facing aesthetics matter on a restaurant patio, and neighbors and adjacent tenants are less likely to complain about a glow than about a column of flame.
The adjustable directional bracket lets you angle the heat pattern, which is how you handle a patio that is tighter on one side. Owners also like that it runs on 110V at about 2A, so a smart control or timer can be added without a 240V circuit and a bigger electrical panel.
Owner feedback is strongest on heating performance and build quality, and most owners pair it with a remote because the wall switch is not always where you want it. Reported drawbacks are consistent: professional installation for gas, electrical, and mounting is not optional, wind measurably shortens the throw, and a few owners reported bird nesting under the heat shield or rust appearing after installation.
On warranty, this is the detail that gives operators pause. The listing states 1 year residential and 90 days commercial. A 90-day commercial term is short for a unit you intend to run every cool evening for a decade, so treat the warranty conversation as part of the purchase, not an afterthought.
How it performs on a covered patio
On a covered patio with a pergola or awning, mounted at 96 inches or above with a clear line of sight to the tables, one Platinum covers a seating zone of roughly six to eight two-tops. Mount two in a row and you have a continuous band of warmth with no gaps for guests to sit in.
Because it hangs, the floor stays clear for servers, for a rolling cart, and for cleaning. On a rooftop deck where floor area is the scarce resource, that alone can justify the higher tier over any tower.
Where it falls short
Wind is the honest limitation. Radiant heat travels in a straight line, and wind carries the cone downwind, so an exposed rooftop with steady crosswinds will lose coverage no matter which brand you buy. Wraparound screening or a wind-rated structure fixes it; a better heater does not.
The price tier is also real, and it comes with an install bill. Gas line work, mounting hardware, electrical for controls, and a licensed contractor all land on top of the unit. Operators with a smaller budget are usually better served by a portable or freestanding model.
4. Bromic Tungsten Smart Heat: Best Turnkey Freestanding Heat
Bromic Tungsten Smart Heat Freestanding 11000W Gas Patio Heater – Natural Gas (NG), 500 Series, 110V, Black Finish – BH0510005
38000 BTU
215 sq ft coverage
Freestanding
110V
85 in tall
Pros
- Same ceramic glass infrared burner class as the Platinum
- No wall or ceiling structure needed
- 215 sq ft of stated coverage per heater
- Tinted ceramic fascia keeps glare down
Cons
- 124 lb frame is hard to reposition on a public patio
- Only one owner review so far
- 36 in floor clearance required
The Tungsten is the freestanding member of the Bromic line, and it is the compromise between the Platinum’s mounting demand and a basic tower. It puts 38000 BTU across a stated 215 square feet using the same tinted ceramic glass infrared approach, in an 85-inch floor-standing body you do not have to hang from anything.
That makes it the pick for patios with a good view or an open sky but no structure to mount to. If you are leasing the space and cannot drill into a wall or beam, a freestanding unit with the same heat pattern as your premium wall model is a sensible middle path.
Because it runs on 110V, you can add a smart control or timer the same way you would on the Platinum. The directional bracket is also carried over, so you can angle output toward the seating rather than toward the property line.
Be honest about the evidence here. There is a single owner review on this listing, so the performance picture here comes from the shared platform of the Bromic infrared line rather than from a deep owner base. If you are staking a whole patio season on this unit, treat it as a lower-confidence pick than the Platinum.
How it performs on a restaurant patio
On an open-air terrace with steady foot traffic, the freestanding body is a clean answer. It needs 36 inches of floor clearance on all sides, which means you are placing it at the edge of a zone, not between two tables, and the 215 square foot coverage means you are planning for one unit per seating group rather than one per patio.
The stainless steel construction is the right call for a unit that lives outside through a full season. Corrosion is the failure mode that ends cheap outdoor heaters, and stainless buys you a longer service life.
Where it falls short
At 124 pounds, this is not a heater staff will casually reposition. That is a deliberate stability choice on a public patio, but it also means your layout is set at install and lives there until someone schedules a move with a dolly.
Review depth is the other gap. One review is not a reliability record, and the warranty line points to the manufacturer site for registration rather than stating terms, so confirm coverage with Bromic before it goes on an install order.
5. SunGlo A242B Portable: Best Value 50000 BTU Natural Gas Dish
SunGlo Portable Patio Heater, natural gas, black, 50,000 BTU
50000 BTU
88 lb freestanding
Disk reflector
Battery ignition
Natural gas
Pros
- 50000 BTU paired with a wide aluminum disk reflector
- Battery ignition means no 110V circuit to run
- Large disk reflector broadcasts radiant heat over a broad area
- Natural gas removes tank hauling from the closing checklist
Cons
- Hose and fittings are not included
- 88 lb weight limits how often staff can move it
- 1-year parts-only warranty
The SunGlo A242B is the one we keep coming back to for operators who want a lot of heat and simple logistics. It delivers 50000 BTU from a large aluminum disk reflector, sits at 88 pounds, and ignites on batteries, so there is no electrical circuit to run to the patio at all.
That battery ignition is a quiet but meaningful operational advantage. Restaurant patios are awkward places to get power to, and a heater that needs no 110V run can go on a patio that a wired unit could not.
The disk reflector is a different geometry from the tube-and-baffle towers. It broadcasts radiant heat outward over a broad area rather than focusing it, which makes it a good fit for a patio where tables are spread in a ring around the heater rather than lined up in a row under a structure.
Owners report immediate ignition, strong output, and easy assembly, and several have bought additional units after the first one. The most common complaint is the one to plan around: no hose or connection fittings are included, so that purchase is on you before the heater is usable.
Long-term owners describe years of reliable service, and the feedback specifically notes that natural gas removes the tank replacement routine. If your closing checklist currently includes hauling propane cylinders, that is the operational win that justifies the tier.
The warranty is 1 year parts only, which is thinner than most. Know that before you spec it for a multi-season install, and ask the manufacturer about burner and emitter availability for this model.
How it performs on a restaurant patio
Plan this as a zone heater placed near the center of a seating cluster, with clear space around it. At 88 pounds it is a deliberate unit, not a carry-it-to-the-bar appliance, so set it where it will live and design the patio around it.
Because the reflector is broad rather than directional, it works well on open-air dining where wind comes from multiple directions and you would lose a narrow throw zone anyway. On a covered patio, the same geometry puts some heat into the structure where you do not need it, so a wall-mounted unit would be more efficient there.
Where it falls short
Missing fittings are the practical trap. Budget for the natural gas connector and any additional length before the unit arrives, and confirm the connection size matches your gas riser so your plumber is not making a special trip.
The 1-year parts-only warranty is the other gap, combined with limited review volume. For a permanent rooftop install where a failure means a closed patio, either pair this with a spare emitter on the shelf or move up a tier.
6. Sunglo A244V-E: Best for Patios Heavy on Ceiling and Light on Floor

Sunglo 50000 Btu Natural Gas Hanging Patio Heater with Electronic Ignition – A244e
50000 BTU
Hanging ceiling mount
24V electronic ignition
Silver finish
Natural gas
Pros
- Hanging design keeps the patio floor clear for service traffic
- Fully automated ignition needs no manual lighting at open
- 50000 BTU radiant output suits a tight covered zone
- Built-in safety shutoff control
Cons
- Requires a 24V electrical circuit in addition to gas
- Switch timer and control device are not included
- Single owner review only
The Sunglo A244V-E solves a specific restaurant problem: a patio where the floor is already spoken for. Hanging the heater from a structure instead of standing it on the ground gives you 50000 BTU of radiant output with no tower footprint, which matters on a rooftop deck, a beer garden, or a narrow terrace along a building.
The fully automated ignition system means the heater lights itself. For a bar or a patio that opens at 4 pm in the dark, that removes a manual step from the opening checklist, and the built-in safety shutoff control cuts the gas if the unit is disturbed.
Two things to plan. It needs a 24V electrical connection for ignition, so this is a gas install and an electrical install, and it needs a switch, timer, or control device that is not included. A hanging heater with no remote is a heater your staff walk to.
More Top Picks Evanston To Reopen Dog Beach In March After 3 Years Of High Water Levels
Evidence here is thin, with a single owner review on this listing. The design logic is sound and the platform is long-established, but treat the review record as unproven rather than as validation.
How it performs on a restaurant patio
This is a good match for a semi-enclosed terrace with a beam or a purlin to hang from, where tables sit in a line under the structure. A hanging unit at 50000 BTU concentrates the heat over a smaller footprint than a freestanding dish, which is what you want when the seating is under cover.
It is also useful for seasonal layouts. If your patio furniture moves for events, a hanging heater stays where it is while the tables come to it, instead of a heavy tower being wheeled through a crowd.
Where it falls short
The 24V requirement is the real constraint. Running low-voltage control wiring across a patio is straightforward for an electrician who is already on site, but it is a second trade and a second inspection point in a buildout that may have assumed gas only.
Because it hangs, the structure has to be able to take the load and the heat. Operators with fabric awnings, tensioned canopy material, or lightweight pergolas should check the material temperature limits before mounting anything above a guest.
7. SunStar 80000 BTU Ceramic: Best High-Output Heater for Indoor Zones
SunStar Heating Products Infrared Ceramic Heater- Natural Gas 80,000 BTU
80000 BTU
Aluminized steel
Aluminum reflectors
Remote control
14 ft mount height
Pros
- 80000 BTU covers a large footprint from one burner
- Aluminized steel body resists corrosion in humid service
- Reflectors angle from horizontal to 30 degrees
- Remote control adjusts heat without walking the floor
- Only 16 lb to lift onto a bracket
Cons
- Rated indoor only and not for an open patio
- 14 ft minimum mounting height with large clearance zones
- Only five owner reviews
We include this one because it is a genuine 80000 BTU natural gas infrared ceramic heater at a price tier that most operators never look at, and because it exposes a mistake buyers make constantly: reading a high BTU number without reading the rating label. This unit is listed for indoor use.
That is not a flaw in the heater, it is a flaw in the fit. The listing specifies a 14-foot minimum mounting height above finished floor and clearances from combustibles of 49 inches above, 99 inches below, and 49 inches from the sides. Those are the numbers for a high-bay indoor space, not a patio with umbrellas.
Where it belongs is an indoor zone inside a restaurant: a high-ceilinged dining hall, a covered structure that is enclosed on three sides, a prep or service volume. At 16 pounds it is light to lift onto a bracket, which is a real advantage in a retrofit.
The aluminized steel construction and aluminum reflectors are built for a long service life in humid indoor air, and the remote control lets staff adjust output without walking the floor. Owners rate the build and the value highly across a small review set.
How it performs in service
In a tall indoor space, the adjustable mounting angle from horizontal to 30 degrees is the useful feature. It lets you aim the throw across a room rather than straight down into a floor, which is how you get even coverage without overloading one zone.
For an operator running an enclosed sunroom or a covered dining structure that has walls, this class of ceramic heater is a legitimate alternative to a patio tower, and the remote makes daily control simple.
Where it falls short
It is not a patio heater, and buying it for an open-air patio creates a compliance problem rather than a comfort problem. Check the rating label and your local code before it goes anywhere near a dining area.
The clearance envelope is large, and the 14-foot mounting height is out of reach for most restaurant structures without engineered supports. Owners also flag that the review base is small, so plan on sourcing replacement emitters and burners through commercial channels.
8. SunStar 60000 BTU Wall-Mount: Best for Commercial-Only Installations
SunStar Natural Gas Heater Infrared Ceramic, 60000 Btu
60000 BTU
1000 sq ft stated coverage
Wall mount
Commercial only
Licensed installer
Pros
- Explicitly commercial rated and not approved for residential use
- 1000 sq ft of stated coverage from one wall burner
- Wall mount keeps the floor free for queueing servers
- Draws only 0.4A so the electrical run stays simple
Cons
- Requires licensed contractor installation and code compliance
- Needs 4 CFM mechanical ventilation per 1000 BTU/hr
- Only three owner reviews
This is the only heater in the roundup whose listing states plainly that it is not approved for residential use. It is designed for commercial buildings, which is exactly the category a restaurant operator wants, and at 60000 BTU with a stated 1000 square foot coverage it is built for volume rather than a single patio corner.
Wall mounting at 21.63 inches deep and 7.75 inches tall keeps it tight to a building face, so it fits along a rear wall where a floor unit would block a walkway. Draw is only 0.4 amps, which means the electrical side of the install is a minor part of the job.
The mechanical ventilation requirement is the specification to read twice. The listing calls for 4 CFM of mechanical ventilation per 1000 BTU/hr of output, and installation and service must be performed by a licensed contractor who conforms to local codes. Those are commercial building requirements, not patio requirements, so this unit belongs in an enclosed or semi-enclosed commercial volume.
One procurement note: the brand field on this listing reads GUM rather than SunStar, which usually indicates a distributor listing. Verify the actual manufacturer of record and the warranty before this goes on a commercial install order.
How it performs in service
At 60000 BTU with a stated 1000 square foot envelope, this is a unit for a large covered terrace, a rooftop dining room with walls, or a semi-enclosed outdoor bar structure. The wall mount keeps the floor open for a queue or a standing area, which is where most of the covers are.
The infrared ceramic technology and the 41-pound body make it a retrofit-friendly option in an existing structure where a freestanding tower would be in the way of service traffic.
Where it falls short
The ventilation requirement and the licensed contractor mandate rule out casual installation. If your patio is fully open air, you do not need a unit with commercial building ventilation provisions, and this one will not be the simplest path.
Review depth is minimal at three reviews, and the brand discrepancy on the listing is a real procurement risk. Ask for the installation manual and the certification paperwork before signing.

40000 BTU
Dual fuel
Stainless steel
104 sq ft
Related Reviews 10 Best Squirrel Traps for Attics (October 2026) Trusted Reviews
Adjustable temperature
Pros
- Runs on natural gas or propane from the same body
- 40000 BTU radiant output with adjustable temperature
- Stainless steel pedestal suits a small terrace
- Compact coverage footprint fits tight bistro patios
Cons
- Single owner review and it rates the unit 1 star
- Owner reports noticeable noise during operation
- Long-term reliability is unverified
The Calcana is on this list for one reason: dual fuel. It runs on natural gas or propane from the same body, which makes it the natural fallback for an operator whose patio is not ready for a hard-piped gas line but who plans to get there. You can start on propane during a buildout phase and convert to natural gas later without replacing the heater.
Output is 40000 BTU of radiant heat with adjustable temperature, and the stated coverage is 104 square feet. That is a genuine bistro-scale number, sized for a small terrace or a cluster of four to six tables rather than a full dining patio.
The stainless steel pedestal body is built for outdoor use, which is a plus on a rooftop or a sidewalk patio exposed to weather year-round.
We want to be straight about the evidence. There is a single owner review on this listing and it is a 1-star rating, with the complaint that the unit is loud in operation and works against a calm patio atmosphere. Noise on a dining patio is a real design failure, and one review is not a reliability record either way. If noise tolerance is tight, test before you commit to a full patio.
Where it makes sense
The dual-fuel capability is the deciding factor for operators in a transitional situation, and the compact 104 square foot coverage is a clean match for a small bistro patio where a larger heater would overwhelm the space.
It is also a useful backup unit. Operators running two patios can keep one heater on natural gas and a second unit ready to move to a pop-up or event space on propane without a second fuel decision.
Where it falls short
Noise is the practical concern for dining, and a heater you can hear across the table changes the room no matter how well it heats. Ask for a demonstration or an owner reference in a hospitality setting before you buy for a quiet dining patio.
Coverage is also modest. At 40000 BTU across a 104 square foot stated envelope, a larger terrace will need several units, and the single-review record makes long-term parts availability something to confirm with the manufacturer before install.
How Many Natural Gas Patio Heaters Does Your Restaurant Patio Need?
Most operators get heater count wrong in the same direction: they buy one unit for a patio that needs three. The rule of thumb we use is straightforward: divide the patio into seating zones of four to six tables, then heat each zone rather than trying to cover the entire footprint with one oversized unit.
The second rule is to size for the seating, not the concrete. A 600 square foot patio with 24 chairs spread across the edges is a different problem from a 600 square foot patio with the same 24 chairs pushed into two tight clusters. Heat the clusters.
Start with the manufacturer’s stated coverage per unit. The XL-Series covers a 15-foot diameter, the Bromic units are rated at 215 square feet each, and the SunStar wall-mount lists 1000 square feet. Treat those as the design input and confirm them against your wind exposure, because coverage figures assume a calm night.
Spacing is the next constraint. Heaters spaced too far apart leave cold aisles between warm zones, and heaters spaced too close waste fuel heating each other. Plan the layout in zones with overlap at the edges, then walk the patio at night with the heaters on before you finalize anything.
If you are converting from propane, our natural gas conversion kit guide covers the fitting and connector questions that come up during that kind of switch, though patio heater burners use their own connection sizes.
Wind and mounting height belong in the same conversation as count. A unit mounted at table height in an open courtyard loses a large share of its throw to any breeze, while the same unit hung at 96 inches under a structure keeps its cone pointed at the tables. Open-air patios get freestanding or pedestal units and more of them; covered patios get fewer, higher, directional units.
The conflict restaurant patios hit most often is overhead clearance. Umbrellas, awnings, and pergola beams all occupy the space a directional heater wants, and municipal outdoor dining programs sometimes cap heater height. Measure the vertical envelope from the table to the lowest obstruction before you order a wall or hanging model, and check your city’s outdoor dining permit for height limits.
Natural Gas vs Propane: What a Patio Heater Costs to Run All Night
Consumption math is the part most comparisons skip. A 50000 BTU burner running four hours a night burns 200000 BTU, which is two therms, or roughly 0.2 MMBtu. Multiply that by your number of heaters and your service nights, and you have the number your gas bill will respond to.
Where natural gas wins is cost per MMBtu. Commercial natural gas is consistently priced well below propane on a delivered-energy basis, and the gap widens at commercial volumes with a dedicated meter. For a restaurant running heaters nightly through a shoulder season, that gap is usually the difference between a fuel line item you notice and one you do not.
The other natural gas advantage is operational. Propane on a restaurant patio means cylinders on site, a swap during service, a leak check, and a closing task. Operators describe that logistics as the single biggest complaint about propane, and it is a staffing cost that does not show up on an invoice. It shows up in the schedule and in the complaints from your team at close.
The honest counterweight is the install. A hard-piped natural gas run from your meter to the patio, with permits, a licensed gas fitter, pressure testing, and inspection, is a project. It is also a one-time project that removes the recurring cylinder handling for the life of the patio, and it usually adds electrical work when you want smart controls on the units.
If your patio is seasonal, a landlord property, or a lease you may not renew, the Calcana dual-fuel approach is the pragmatic middle: propane now, natural gas later if the site earns a permanent install. If you own the site and the patio is going to be heated for seasons, plan the gas line from the start.
Safety Certifications and Clearance Rules Restaurant Patios Face
Ask for the certification number, not the phrase commercial grade. Residential units are routinely sold into commercial settings, and they are not rated for nightly continuous duty. The two standards to look for on a gas-fired patio heater are ANSI Z83.26 with CSA 2.37, and for gas-fired radiant tube heaters ANSI Z83.20 with CSA 2.34. ETL listing or UL listing from Intertek or a similar body covers the electrical and control side.
Continuous duty is the word that separates a restaurant heater from a patio toy. A unit rated for intermittent residential use is being asked to do something different when it runs six hours a night for a hundred nights.
On fuel safety, three features matter. Thermocouple flame failure protection shuts the gas valve when the flame goes out, which is the base standard on any unit worth installing. Oxygen depletion systems measure the surrounding air and shut down if combustion is starved, and those matter in semi-enclosed structures rather than fully open patios.
Tip-over shutoff and anti-tilt sensors matter for any wheeled or pedestal unit near a service route. The XL-Series has an auto tilt shutoff, and the SunGlo disk heater has a safety shut-off control mounted on the body. A hard-mounted wall or hanging unit does not need one because it cannot tip.

Clearance numbers come from the installation manual, not from the marketing copy, and the heaters in this roundup show how much they vary. The Golden Flame Resort model lists 36 inches above and 24 inches to the sides. The Bromic Platinum requires 96 inches of clearance for wall and ceiling installation. The SunStar 80000 BTU ceramic unit requires 49 inches above, 99 inches below, and 49 inches from the sides, with a 14-foot minimum mounting height. A heater that is correct for your patio is a heater whose clearance envelope fits your patio.
Clearance is also where umbrellas and awnings come back into play. A directional wall or hanging heater throws a defined cone, and a fabric umbrella, a canvas awning, or a tensioned canopy edge inside that cone is a fire hazard and a melt risk. Measure with the heaters running, not on a drawing.
Installation, Permitting, and Local Code for Commercial Heaters
Start with your Authority Having Jurisdiction, which is the local fire marshal, building department, or planning office that will sign off. For a restaurant patio, the gas line extension, the electrical for controls, the structural work for a hanging unit, and the outdoor dining permit may all be reviewed by different people, and the order you approach them saves weeks.
Bring the heater specifications to the first meeting: BTU output, fuel type, mounting type, and the clearance dimensions from the manual. A fire marshal who sees the numbers up front is far easier to work with than one who is reviewing a generic patio heater request.
Municipal restrictions are the surprise for many first-time operators. Some cities cap the height of patio heaters, some cap umbrella and structure height, and some restrict open-flame equipment in certain districts or on certain streets. Some also limit the size of the outdoor dining area as a condition of the permit. If you have never run an outdoor dining program, this is the check to do before you buy anything.
Use a licensed contractor for both gas and electrical. The SunStar 60000 BTU wall-mount states it plainly: installation and service must be performed by a licensed contractor and must conform to local codes. That is standard for commercial work, and the inspection is what makes the install legitimate rather than a liability during an insurance review.
Then plan for maintenance on a commercial schedule, not a residential one. Check the reflector and emitter for soot and debris monthly during service, inspect the burner and flame pattern for irregularity, confirm the thermocouple and shutoff devices are functioning, and have the gas connection and flex line inspected at least annually by your contractor.
Operators who run heaters nightly should keep a spare emitter, burner, and ignition part on the shelf. A missing part during a Friday rush is a lost patio, and the standard parts list for a given model is worth knowing before you need it. If your site has any other gas equipment, our natural gas grill guide covers the connection and safety basics that carry over.
Finally, confirm your gas utility offers a commercial rebate or efficiency program. Some utilities have commercial natural gas programs available to restaurant and small commercial accounts, and it is a question worth asking once during the install quote.
Frequently Asked Questions
What are the best outdoor heaters for restaurants?
The best outdoor heaters for restaurants are hard-piped natural gas radiant units mounted at height above the seating. The Golden Flame XL-Series at 45000 BTU is the easiest all-around pick, the Bromic Platinum at 39800 BTU is the strongest wall and ceiling option under a structure, and the SunGlo A242B at 50000 BTU covers open-air patios where no mounting structure exists. Choose commercial-rated units certified to ANSI Z83.26/CSA 2.37 or ANSI Z83.20/CSA 2.34.
What is the best natural gas patio heater?
The best natural gas patio heater depends on your structure. For a covered patio with beams or a pergola, a wall or ceiling-mounted directional unit such as the Bromic Platinum Smart Heat 500 is the strongest choice because heat is aimed at tables instead of the night sky. For open-air dining with nothing to mount to, a freestanding tower or pedestal unit like the Golden Flame XL-Series is more practical.
What type of gas patio heater is best for a restaurant?
Infrared radiant heaters are the correct class for open-air restaurant patios because they warm guests, tables, and chair backs directly rather than heating the surrounding air, which means they still work in breezy conditions. Mounting style is the second decision: post-mount or freestanding for open patios, wall or ceiling for covered patios, and hanging for patios where floor space is limited. Coverage figures should size to seating zones rather than total patio square footage.
What are the drawbacks of using outdoor propane heaters?
The main drawbacks of propane patio heaters in a restaurant setting are logistics and running cost. Tanks have to be stored, hauled, swapped during service, and leak-checked, and running out mid-service is a recurring complaint from operators. Delivered propane also costs more per MMBtu than commercial natural gas, so a nightly patio burns through fuel budget faster. Hard-piping to natural gas removes the handling labor and lowers the fuel cost per unit of heat.
How much does it cost to run a natural gas patio heater all night?
It depends on output and hours, and the math is simple. A 50000 BTU burner running four hours consumes 200000 BTU, which equals two therms or about 0.2 MMBtu. Multiply that by the number of heaters and the number of service nights in your season to estimate total consumption. Because commercial natural gas is priced well below propane per MMBtu, the fuel line is usually modest compared with a one-time gas line installation.
What safety certifications should a commercial patio heater have?
Look for a gas-fired patio heater certified to ANSI Z83.26 with CSA 2.37, or a gas-fired radiant tube heater certified to ANSI Z83.20 with CSA 2.34, plus ETL or UL listing for the electrical and control components. Confirm the unit is rated for continuous commercial duty rather than intermittent residential use. On the patio itself you also want thermocouple flame failure protection, oxygen depletion shutdown for semi-enclosed areas, and a tip-over or anti-tilt switch on any wheeled or pedestal unit.
Conclusion: Which Natural Gas Patio Heater Fits Your Patio
The Golden Flame XL-Series is our pick for most restaurant patios because it combines 45000 BTU of output, variable heat control, pilotless push-button ignition, and a weighted wheeled base in a package that does not demand a structure to hang from. It is the simplest unit here to justify to a general manager.
For a covered patio with real beams or a pergola, step up to the Bromic Platinum Smart Heat 500. Its 215 square foot coverage and adjustable directional bracket aim heat at the tables instead of the night sky, which is the difference between a comfortable patio and a warm one on a windy night.
For open-air dining with no mounting structure, the SunGlo A242B gives you 50000 BTU from a broad disk reflector with battery ignition and no electrical run. Where floor space is the constraint rather than structure, the Sunglo A244V-E hangs the heat instead of standing it.
Before you order anything, confirm two things: the clearance envelope fits your patio including umbrellas and awnings, and your Authority Having Jurisdiction approves the install. Those two checks eliminate most of the problems we saw operators run into.
