Choosing outdoor heaters for restaurants is less about picking a heater and more about picking a heating strategy. Patio heaters warm people directly with radiant heat rather than heating the air, and the right choice depends on your patio size, how exposed it is, and whether an electrician or gas fitter is part of the install.

Two patterns jump out of this table. Six of the ten are propane towers, which tells you where the bulk of restaurant demand sits. Three are plug-in or hardwired electric units, and they are all much smaller in output, sized for a table or a screened corner rather than a whole patio.
The one wall-mounted commercial unit on the list is also the one with the largest stated coverage, at 430.5 sq ft. That is not a coincidence: mounted radiant units sit above head height and project downward, so they lose less of their output to moving air than a freestanding flame tower.
1. Amazon Basics 46,000 BTU Portable Propane Patio Heater – Best Overall Freestanding Pick
Amazon Basics 46,000 BTU Portable Outdoor Propane Patio Heater with Wheels, Commercial & Residential, Easy to Use, with Water Tank, Havana Bronze, 32.1 x 32.1 x 91.3 inches
46,000 BTU propane
324 sq ft coverage
91.3 in tall, 40 lbs
Standalone with wheels
Pros
- Strong controllable radiant heat over 18 ft diameter
- One-touch ignition lights on the first try usually
- Built-in wheels for repositioning between service areas
- Water-fillable base adds wind stability
- Powder-coated finish that survives multiple seasons
Cons
- Assembly instructions are confusing and setup can take 1.5 to 2.5 hours
- Small base fill hole makes adding weight tedious
- Heat reflector is smaller than ideal so the warm zone is tighter than the rating suggests
This is the unit I keep coming back to. It sits in the middle of the restaurant band, and that is exactly why it is the workhorse: operators in hospitality forums talk about 40,000 to 50,000 BTU as the restaurant standard, and this lands in the middle of that range with 46,000 BTU across a stated 324 square feet.
Weighing in at 40 pounds on its own, and more with a full 20 lb tank, it is heavy enough to stay put in a gust but still movable on its built-in wheel kit. The water tank in the base is the detail I appreciate most for a patio with steady evening wind, because it lets you add ballast without dragging sand in from the car park.
The tilt safety auto shut-off valve is a real safety valve, not a marketing label, and it cuts fuel if the unit goes past its angle. One-touch ignition gets a server from the walk-in to a lit heater without a lighter, which matters when staff turnover is high. Owners report a genuinely wide, controllable heat band and praise the finish for holding up over multiple seasons.
The recurring complaint is not performance, it is assembly: unclear instructions, tedious packaging removal, and a base fill hole that is smaller than it should be.
What to check before you buy
Allow a full afternoon for the first build. Owners consistently report 1.5 to 2.5 hours with the instructions as supplied, so budget a staff member rather than your best technician. Plan where the tank change happens, because at 40 pounds plus the tank this is a two-person job on a busy site.
If your patio is under a pergola with a solid roof, this works well. If it is a fully open rooftop, the heat column on a flame tower is the weak point and you should be sizing for two units rather than one.
Where it falls short
The pole is fixed height at 91.3 inches, so you cannot drop the heat closer to seated guests on a cold night. Several owners also describe the heat radius as tighter than the 18-foot figure suggests, which is a fair warning for a large open deck.
Our advice: use it as the anchor heater and add a mounted infrared unit over the tables furthest from it. The combination of one strong freestanding unit plus directional overhead heat covers far more square footage than two flame towers fighting each other.
2. DR. INFRARED HEATER 4500W Carbon Infrared Wall Unit – Best Mounted Option
DR. INFRARED HEATER 4500W Electric Infrared Patio Heater, Wall/Ceiling Mount, IPX2 Weatherproof, 208V-240V, Remote Control for Patio, Workshop, Restaurants & Outdoor Dining
4500W carbon infrared
430.5 sq ft coverage
Wall or ceiling mount
Hardwired 208-240V
Pros
- Instant radiant heat with no warm-up time
- Silent with no fan noise
- fumes or open flame
- Remote control with three levels plus a 1-24 hour timer
- All mounting hardware included
- ETL safety certification
Cons
- Needs a hardwired 208-240V circuit rather than a standard outlet
- Highly directional so warmth is felt only within a few feet
- Much less effective on a fully open windy patio
This is the only hardwired commercial unit in our group and the only one rated for 240 volts, which changes the conversation from buying equipment to running an install. At 18.75 amps you are on a dedicated circuit, so budget for an electrician and check your panel capacity before you commit.
What you get in return is the cleanest heat in the category. There is no combustion, so no fumes, no flame, no CO concern and nothing to refuel. Operators running screened or semi-enclosed patios rate it well for that reason, and it also suits a smoking section where a flame unit would be a problem.
Coverage is stated at 430.5 sq ft, the largest on our list, and that figure is believable because the unit mounts above head height and throws heat down and out. Carbon infrared elements also hold their output far better in moving air than a quartz or open flame element.
The remote with three power levels and a 1 to 24 hour timer is the piece we would keep if we could only keep one. It means a manager can set the patio to warm itself before doors open and step it down as the last table clears.
What to check before you buy
Get the electrical scope done first. The unit is hardwired and no power cord is included, and the lower-power 120V variants in the same line are a different product with a different output figure. Confirm which voltage your panel can serve before the unit is on the wall.
Check mounting height and clearance carefully too. Owners note that the front grates and glass run very hot, so the install height has to respect the clearance the manual specifies, particularly over a patio where guests stand and talk.
Where it falls short
It is directional, full stop. Guests more than a few feet out report feeling little warmth, and on a fully open windy patio the shortfall is bigger. This is a covered or screened patio product, not an exposed rooftop product.
One more detail worth flagging: there is no power-state memory, so after any power interruption the unit has to be switched back on with the remote. A few owners also report LED flicker on shared circuits at lower settings because of how the output is regulated.
3. Pamapic 89 Inch Pyramid Patio Heater – Best for Patio Ambience
Pamapic 89″ Pyramid Patio Heater Outdoor, Propane Flame Tower with Quartz Glass Tube, Outdoor Heaters with Wheels & Cover for Deck, Porch, Backyard, Garden, Hammered Bronze
48,000 BTU propane
15 ft diameter coverage
89.4 in tall quartz glass tower
61.7 lbs with wheels
Pros
- Visible quartz glass flame column that doubles as patio lighting
- Good coverage across a 15-foot diameter area
- Tall profile throws heat down over seated guests
- Wheels and a weather cover included
Cons
- Heat concentrates high on the tower so seated guests need to sit close
- Nearly 62 pounds makes repositioning awkward despite the wheels
- Flame output less even than a conventional mushroom-style heater
If your patio sells atmosphere as much as warmth, this is the one. The visible quartz glass flame column is a genuine design element, and at 89.4 inches it reads as a piece of restaurant furniture rather than a box appliance.
Output is 48,000 BTU with coverage stated to 15 feet in diameter, which puts it in the same band as the other freestanding propane units here. Multiple finishes are available, including stainless steel and black, so it can be matched to the finish of the rest of the patio furniture.
The tall profile is the whole design. Heat concentrates at the top of the tower and disperses downward, which means guests seated underneath get warmth without the heater sitting in a walkway or against a table edge. Wheel and cover are included, which is more than many competitors offer.
Reviewers are split in one specific way, and you should know it before ordering. People who sit close love it. People at the outer edge of a 15-foot circle feel the heat late in the evening.
What to check before you buy
Measure the clear height above the unit and the clear radius around it. A tower this tall needs 89 inches of vertical space plus the tank, and the heater needs to sit where it does not obstruct a server’s path between the kitchen and the table.
Check the finish against your existing furniture and umbrellas. Owners consistently remark on how much the flame column contributes after dark, which is a stronger reason to choose this than raw output alone.
Where it falls short
At 61.7 pounds it is the heaviest unit on our list, and the wheels are not a substitute for a second pair of hands. Moving it across a patio takes planning, not improvising.
The flame itself is also reported as less even than a conventional mushroom reflector. If your priority is a broad, even heat field rather than an attractive flame, our value pick below is the more consistent performer.
4. Thermo Tiki Commercial LP Gas Patio Heater – Best Value Commercial Tower
Thermo Tiki Outdoor Propane Patio Heater – Commercial LP Gas Porch & Deck Heater – Black
38,000 BTU true rated
15 ft diameter coverage
7 ft 6 in steel and aluminum
ANSI, CE and CSA compliant
Pros
- Genuine commercial styling that matches heaters seen at bars and hotels
- Clear picture-led instructions with well labelled hardware
- Ceramic-glass element gives an attractive visible flame
- Tool-free covers come off quickly for tank changes
Cons
- Some reports of the ceramic glass tube discolouring or burning on one side
- 57 pounds plus the tank means a two-person move
- Sharp un-honed sheet metal edges during assembly
This is the unit that reads as restaurant equipment rather than garden equipment, and owners say so directly. The 7 ft 6 in commercial steel and aluminum tower, the ceramic-glass heating column and the protective mesh are all visual cues that guests read as professional.
Here is the number that matters for procurement: the peak output is quoted at 45,000 BTU but the true rated figure is 38,000 BTU. That distinction is exactly what an inspector or a utility conversation turns on, so quote the true rating in any sizing plan you write.
It is ANSI, CE and CSA compliant, carries a 90 day limited manufacturer warranty, and ships in build form with a heavy-duty regulator and a pre-attached flexible hose. The 20 lb tank is separate, as you would expect. Assembly is the easiest in this group because the instructions are picture-led and the hardware is labelled.
A built-in safety valve shuts off fuel if the unit is tilted, and a pilot light covers the gap between service periods. The rust, fade and corrosion-resistant finish is aimed at sun and salt air, which is the right call for a coastal terrace.
What to check before you buy
Check the flame column before first service and photograph it. A few owners report the ceramic glass discolouring or burning on one side over time, and having a dated reference image is what makes a warranty conversation straightforward.
Plan the tank change route. The covers come off without tools, which is genuinely good, but at 57 pounds the unit itself does not move one-handed. Budget a second person or a rated hand truck.
Where it falls short
Some buyers feel the radiant heat is weaker than the output figure implies for what it costs, and the raw sheet metal edges are sharp enough to mention during assembly. Email customer service has been reported as slow on warranty issues, which is a real factor if you depend on parts quickly.
This unit also has the widest rating spread in our group, with a meaningful share of one-star reviews alongside the majority of five-star ones. Treat the element durability as the one risk you are accepting in exchange for the commercial build.
5. SereneLife 1500W Carbon Fiber Infrared Tower – Best for Small Seating Areas
SereneLife Infrared Patio Heater, 1500W Electric Standing with Remote Control, IP44 Approved, Odorless, Three Power Settings, Indoor/Outdoor for Restaurant, Backyard, Garage, Decks
1500W carbon fiber infrared
25 sq ft coverage
120V plug-in, 12.5 A
57 in tower, 21.6 lbs
Pros
- Odorless and silent with no propane to store or refill
- Remote control with three heat settings
- Tip-over
- overheat and mesh guard protection
- Light enough at 21.6 lbs to move between areas
Cons
- Modest 25 sq ft coverage limits it to a single table or gazebo corner
- Directional infrared means guests need to sit within a few feet
- IP44 rating is still short of the IPX5 and IP65 units in this group
This is a table heater, not a patio heater, and understanding that keeps you from being disappointed. At 1500W and 25 sq ft of stated coverage, its job is to keep two to four guests comfortable at one table through a cool evening rather than to warm a deck.
What you give up is tank logistics entirely. It runs off a standard 120V outlet at 12.5 amps, so a hostess can plug it in at the start of service and unplug it at the end with no refuelling schedule and no propane storage question for your insurance.
The carbon fiber element is rated at 88 percent efficiency and ETL certified, and the aluminum alloy frame carries an IP44 weather rating with a stainless steel base cover. A 360-degree tip-over switch, overheat protection and a mesh guard are all present.
This is the lowest-rated unit in our group, and the reason is scope rather than quality. Owners are broadly happy with the heat; they are frustrated that they expected a patio heater and got a seat warmer.
What to check before you buy
Map your tables. One unit per one or two tables is the realistic ratio at this output, so a six-table patio needs a fleet of them, and each needs a nearby outlet. Check that a 120V circuit is genuinely available before committing to a layout.
Confirm the patio is sheltered. The directional throw is the limiting factor, so a semi-enclosed gazebo or a screened corner is the environment this unit is built for.
Where it falls short
Wind is the honest problem. Radiant heat needs line of sight, and a 25 sq ft unit outdoors in a breeze simply has too little output to push through moving air. The IP44 rating is also modest next to the IPX5 and IP65 units further down this list.
Eleven percent of its ratings are one-star, mostly for the same reason: expectation mismatch. If you need to heat a room, look at a mounted unit or a second propane tower instead.
6. Pamapic 50,000 BTU Round Table Patio Heater – Best for Service at the Table
Pamapic Outdoor Heaters for Patio with Round Table Design, Premium 304 Stainless Steel Burner, Triple Protection System Propane Patio Heater for Porch Garden, Residential & Commercial Use
50,000 BTU propane
20 ft diameter, 314 sq ft
Built-in round table top
87.8 in tall
Pros
- Fastest heat-up in the group with one-touch ignition in about five seconds
- 304 stainless steel burner is more durable than mesh burners
- Built-in round table is genuinely useful for drinks and phones in service
- Magnetic locking door makes tank changes fast
Cons
- Arrives in two boxes so assembly cannot start until both arrive
- Three different washer sizes must be sorted during assembly
- Output can feel lower than the 50000 BTU claim on an open patio
The round table is the idea that makes this different from every other tower in the group. Guests get somewhere to put a drink, a phone and a plate, and servers get a surface that stops the crowd forming an awkward ring around a bare pole.
That solves one of the most common complaints we heard from operators: people cluster around a single pole-mounted heater rather than sitting at their own table. Here the heater and the table are the same object, so the seating stays intact.
Output is 50,000 BTU across a stated 20-foot diameter, which is the second widest coverage figure in this group after the mounted 4500W unit. The 304 stainless steel burner is a step up from mesh-style burners, and the conical body is described as wind resistant.
Protection is the strongest package here: tip-over shutoff past 45 degrees, an automatic flame-failure device that closes the gas supply, and one-touch ignition that reaches a warm state in roughly one minute. It is CSA certified and a cover is included.
What to check before you buy
Order early enough for a two-box delivery. Assembly cannot begin until both boxes arrive, and the process involves sorting three different washer sizes, so give it a planned session rather than a gap between lunch and dinner.
Think about the table surface in service terms. A heat source with a tabletop built in needs a wipe-down routine, and on a high-volume patio you will want to assign that to a specific station.
Where it falls short
A handful of owners feel the felt output sits below the 50,000 BTU claim on a fully open patio, which is a recurring theme for any flame unit exposed to wind. Some also report flames burning unevenly on one side of the burner.
The magnetic locking door is a real convenience, but manufacturer contact details are missing from the paperwork. Get a support contact on file before the unit goes into service.
7. FOOWIN 48,000 BTU Propane Pyramid Patio Heater – Best for Compact Patios
FOOWIN Patio Heater 48,000 BTU Outdoor Propane Heater with Wheels
48,000 BTU propane
10 ft radius, 130 sq ft
Quartz glass tube
81.4 in tall, 50.7 lbs
Pros
- Best-looking pyramid design in the group
- Assembly takes around 50 minutes with included tools
- Quartz glass tube adds real ambience after dark
- Cover
- gloves and lifetime warranty service included
Cons
- Heat concentrates at the top of the tower so seated guests must sit close
- One heater may not be enough for a large patio in low temperatures
- Structural parts can arrive bent and included screws strip easily
Smaller footprint, same restaurant output. At 130 sq ft of stated coverage this is the tightest big-output unit here, and for a compact terrace or a narrow courtyard where a 20-foot circle would overhang the space, that is the feature rather than a limitation.
The bronze pyramid styling and quartz glass tube come up again and again in the reviews as the reason people buy it. Owners describe it as a clear visual upgrade from older mushroom-style units, and at 81.4 inches it is shorter than several rivals while keeping 48,000 BTU.
Safety testing is unusually thorough for this class. Every unit passed 10,000 automatic flame-out tests before leaving the factory, the auto shut-off triggers past 45 degrees of tilt, and the pipe is described as explosion-proof with protective netting.
Warm-up is about five minutes. The package includes a waterproof cover, operating gloves and lifetime warranty service, which is a fuller bundle than most rivals ship with.
What to check before you buy
Inspect the frame on arrival before you start assembly. Bent structural parts and soft hardware are the two assembly complaints that come up repeatedly, and both are easier to deal with before screws are in place than after.
Check that the footprint works with your seating. A 130 sq ft heat circle is a tight radius, so the tables need to sit close to the unit rather than being spread across the patio.
Where it falls short
Heat placement is the honest limitation, reported by multiple owners: warmth concentrates at the top of the tower, so seated guests need to be near it. The manual print is also small, which matters if your staff will be reading it rather than you.
If your patio is open and large, one unit will not carry it in genuinely cold weather. Use it as a table-anchored heater in a sheltered corner rather than as the only heat source on the deck.
8. EAST OAK 55,000 BTU Round Table Patio Heater – Best for Maximum Heat Output
EAST OAK 55,000 BTU Propane Patio Heater with Round Table & Stainless Steel Burner, Outdoor Heater with Wheels, Ideal For Large Patios, Gardens, Outdoor Events, and Commercial Use, Bronze
55,000 BTU propane
18 ft heating coverage
Double-layer stainless burner
86.6 in tall, 33.1 lbs
Pros
- Highest BTU rating in the group with furnace-like heat reported by owners
- Fastest setup at about 30 minutes from partly pre-assembled parts
- Patented round tank lid doubles as a table
- One-touch ignition lights in under five seconds
Cons
- Body panels can feel light or thin for the price
- Styling is described as functional rather than attractive
- Some units failed after about a season with the ignition knob losing the flame
This is the highest-rated unit in our group and the highest output, at 55,000 BTU from a double-layer stainless steel burner across a stated 18-foot spread. It is the number to aim at when your patio is large, exposed and needs serious heat rather than ambience.
It is also the lightest gas unit here at 33.1 pounds, and the setup time is the shortest we saw at roughly 30 minutes because the burner and igniter arrive pre-assembled with only three reflector pieces left to fit. For a team doing this across multiple sites, that difference compounds fast.
The patented round propane tank lid doubles as a table with a cut-out for the control knob, so it does the same job as the Pamapic unit above while weighing roughly half as much. One-touch ignition, an adjustable control knob, tip-over shutoff past 45 degrees and flame-out protection complete the package.
Two wheels make it the easiest of the big propane units to reposition, which matters when a server needs to move heat from a waiting area to a bar rail at 7pm.
What to check before you buy
Weigh the build against the output before you commit. Owners describe the body panels as light or thin for the price, and a handful report ignition knob failures after about a season of use, so plan for a possible burner or ignition replacement in year two.
On the other side, the after-sales service is described as exceptionally responsive, including complete replacement units and burner heads sent even beyond the warranty period. For an operator running a season every year, that support record may matter more than the finish quality.
Where it falls short
The styling is functional. If the patio is a customer-facing cocktail bar rather than a dining deck, the appearance may not earn the space it takes. The 4.6 rating also rests on a smaller number of reviews than the rest of this group, so treat it as a strong signal rather than a settled one.
It is a flame unit, so it carries the same wind caveat as every other tower on this list. Pair it with wind screening and do not expect it to heat a fully open rooftop alone.
9. SereneLife 1500W IP65 Infrared Patio Heater – Best for All-Weather Use
SereneLife Infrared Patio Heater 1500W Electric Heater Indoor/Outdoor Use, Portable Stand with Remote Control, IP65 Approved, 360° Tip-Over Safety Switch for Restaurant, Patio, Backyard, Garage, Decks
1500W carbon fibre infrared
20 sq ft coverage
IP65 waterproof, 120V
Height adjustable to 72.8 in
Pros
- No propane to haul
- refill or store
- Adjustable stand height aims heat at a table or a standing bar
- Silent odourless radiant heat
- IP65 sealing for genuine outdoor exposure
Cons
- Short usable cord length so an extension is usually needed
- Blue standby LED never fully powers down
- Stem is under-stressed relative to the heavy base and can bend
The IP65 rating is the headline here. Among plug-in heaters, that is the highest weather sealing in our group, and it is what lets this one sit out through a wet season rather than being wheeled inside after every service.
Height adjustment is the second reason operators like it. The stand adjusts so the element can be aimed at a seated table or a standing bar, which solves a real problem on a patio that serves both. Maximum surface temperature setting is 360 F, with remote control and an LED indicator.
Owners who switch from propane to this unit rarely go back. There is nothing to refill, nothing to store, and it weighs 23.4 pounds rather than 50 or more. A 360-degree tip-over switch, overheat protection and a mesh grille guard cover the basics.
The carbon fibre element warms people without pushing hot air around, and there is no gas line, no combustion and no CO question in an enclosed-adjacent space.
What to check before you buy
Look at the cord. Most of the length runs up the pole, which leaves only a couple of feet at the base, so in practice you will plan an extension and a drip-rated outdoor socket. On a wet-weather site that means a proper weatherproof connection, not a domestic extension reel.
Use the height adjustment. Set the element at head height for a bar rail and lower it toward table height for dining, and this unit is much more useful than a fixed 57-inch tower.
Where it falls short
Like every 1500W unit here, the throw is short. In genuinely cold weather the feedback is that it works best set low and close to the seating, which makes it a supplement rather than a primary heat source.
There is also a durability thread worth weighing: some owners report units cutting out after extended use, and one isolated report of a unit in its box catching fire. The stem-to-base joint is reported as under-stressed when the unit is moved, so lift it rather than drag it.
10. Encyclpo 1500W IPX5 Portable Tower Heater – Best for Portable Spot Heating
Encyclpo Patio Heater for Outdoor Use,1500W Infrared, 36 in Portable Tower Heater, 3 Levels, IPX5 Waterproof, Tip-Over&Overheat Protection for Garage, Indoor, Large Room, Backyard, Home
1500W infrared
3 settings: 600W, 900W, 1500W
IPX5 waterproof
36 in tall, 7.5 lbs
Pros
- Fastest heat-up in the group with warmth within seconds
- Only 7.5 lbs so one person can carry it between areas
- Slim 8 inch footprint leaves table and floor space free
- Truly silent with no fan or odour
- Adjustable thermostat from 40 F to 140 F
Cons
- Small outdoor heat radius and you need to be near it in cold weather
- Tip-over switch is so sensitive that brushing the unit turns it off
- Reported control knob cracking after a few weeks
At 7.5 pounds this is the only unit in the group that one person can carry between a front patio, a rear courtyard and a covered smoking area in a single evening. The 36-inch tower has an 8-inch footprint, so it disappears beside a table leg rather than occupying a corner of the seating plan.
Two high-efficiency carbon fibre wires bring warmth within about a second, with three settings at 600W, 900W and 1500W and a thermostat that runs from 40 F to 140 F. There is no fan, no odour and no combustion noise at all.
Safety features include tip-over auto shutoff, automatic overheat shutoff and a flame-retardant housing, with an IPX5 waterproof rating for indoor and outdoor use. The carry handle is a small thing that turns out to matter when you are moving it four times a night.
This is genuinely useful kit for a small cafe or a venue running several distinct outdoor areas, because it can follow the customers instead of asking them to move.
What to check before you buy
Confirm the outlet position. The power cord is short and the manual advises against extension cords, so this unit works best where a socket sits close to the seating rather than at the edge of a patio.
Position it out of the traffic path. The tip-over switch is very sensitive by design, and owners report that brushing the unit with a chair or a bag switches it off mid-service, which is a real interruption at a busy table.
Where it falls short
It is a spot heater and nothing more. Outdoors in genuinely cold weather, guests need to be near it, and one unit will not carry a dining patio. Treat it as a targeted supplement, not a patio solution.
There are also durability reports to weigh: control knobs cracking after a few weeks and some units ceasing to work after about five months, with replacement described as slow. For a permanent install position, choose a unit with a stronger warranty instead.
How to Choose Outdoor Heaters for a Restaurant Patio
Choosing outdoor heaters for restaurants comes down to four decisions in order: fuel type, output per square foot, wind exposure and install logistics. Get the first two right and the rest is detail. Get fuel wrong and nothing else matters.
Propane vs natural gas vs electric
Propane is the default for freestanding restaurant heaters because it needs no utility work. You can add or remove capacity without an installer, which matters when a patio season is still being planned. The cost is per-hour fuel burn and the logistics of tank swaps during service, and a visible flame that needs a clearance check.
Natural gas is the cheapest to run over a full season because there is no fuel handling at all once the line is in place, and a permanently mounted unit becomes part of the patio rather than part of the furniture layout. The trade-off is a fixed install cost, a permanent line and a longer approval path, so it suits a patio you know you will keep.
Electric infrared is the quiet option: no flame, no fumes, no CO, nothing to refill, and instant heat. It is the right answer for screened and partially enclosed areas, and for indoor-adjacent spaces. Its limits are output and installation, since a 240V hardwired unit needs a dedicated circuit and a plug-in unit tops out around 1500W.
One rule is absolute: never run a gas heater in a fully enclosed space. Radiant heaters of every fuel type work by warming people directly rather than the air, and the one configuration where that logic breaks down is a space that traps combustion products.
How many heaters and how much output
The working rule of thumb is 40,000 BTU of gas output for roughly 100 sq ft of patio, or about 1,500W of electric for the same area as a comfortable target rather than a guaranteed one. Heated patios extend a season into the shoulder months; they do not turn a 30 degree night into summer.
Plan for two heaters on any patio above about 200 sq ft rather than one bigger unit, because a single source leaves guests clustering at one end and cold at the other. On a rooftop, size up for wind, since heat loss is greater at height and the boundary layer at street level does not apply.
A common mistake is positioning heaters between tables rather than above or beside them. Guests need to be in the radiant path, so work from the seating plan outwards rather than dropping units on the patio and seeing where they fit.
Wind tolerance by heating element
This is the difference most buyers miss. Radiant heat travels in a straight line, and wind pulls that line apart.
Flame and quartz tube elements are the most wind sensitive, because the flame and the hot glass need undisturbed air to hold their output. A 50,000 BTU tower in a gust can deliver noticeably less than its rating, which is the single most common complaint operators report.
Carbon fibre, halogen and low-glare infrared elements are the least wind sensitive, and mounted units are more tolerant than freestanding ones because they sit above head height where moving air is slower. If your patio is exposed, weight your selection toward mounted infrared or mounted commercial gas rather than tall freestanding towers.
Whatever fuel you choose, wind screening is the cheapest upgrade available. Restaurant operators in hospitality forums describe pairing heaters with screens, side walls and canopies to hold heat in the seating area, and it works better than most people expect.
Propane runtime and tank swaps during service
A 20 lb propane tank on a 50,000 BTU setting burns through in roughly five to six hours of continuous high output, so a two-hour evening service on a single unit can consume a meaningful share of a full tank. Lower settings stretch that considerably.
Plan the swap. Because these units weigh 40 to 60 pounds before the tank, the swap needs two people and a clear path. Many operators schedule the change between seatings rather than mid-service, and the Thermo Tiki model here uses tool-free covers specifically to shorten that window.
One related risk to think about: run heaters in a single group rather than spreading them across the whole patio, so a fuel problem takes down one zone instead of the entire seating area.
Installation, listing and permit checklist
Work through this list before ordering anything, because a heater that fails inspection is downtime you have already paid for.
Check the listing. ETL, UL and CSA marks are what an inspector or authority having jurisdiction will ask about, and the propane units in this group variously carry ANSI, CE, CSA or none, so know which you have.
Check the weather rating and match it to exposure. IP44 suits a sheltered corner, IPX5 handles open-air service, and IP65 or above is what you want for units that stay out through winter.
Check clearances to combustibles and the required mounting height from the manual, then measure them. Flame units and quartz tube elements both run hot enough to matter to an overhead structure, and a fixed awning changes the required distance.
Confirm the electrical plan. A 4500W unit at 18.75 amps needs a dedicated 208 to 240V circuit and no power cord is supplied, so panel capacity and electrician scheduling belong in your timeline. A 1500W unit at 12.5 amps can sit on a standard 120V outlet.
Then confirm whether a permit is required in your jurisdiction, and whether a gas line connection needs its own approval. This is the step most often skipped and the one most likely to delay opening night.

Frequently Asked Questions
What are the best outdoor heaters for restaurants?
The best outdoor heaters for restaurants are commercial-grade radiant units rated between 40,000 and 55,000 BTU for propane and natural gas, or 1500W to 4500W for electric infrared. A freestanding propane tower is the standard for open patios, a hardwired carbon infrared unit is best for covered or screened patios, and plug-in 1500W towers suit single tables. Match the output to roughly 100 sq ft of patio per 40,000 BTU.
Which outdoor heater gives off the most heat?
BTU is the standard measure for gas patio heaters and watts for electric units. In this group the highest gas output is 55,000 BTU from the EAST OAK round table unit, while the highest electric output is 4500W from the hardwired wall-mounted carbon infrared heater, rated to cover 430.5 sq ft. The plug-in 1500W towers sit at roughly 5,000 BTU, so a 50,000 BTU propane heater delivers about ten times the raw output of a portable electric tower.
What is the most efficient outdoor heater?
Efficiency depends on whether you mean heat per unit of fuel or heat delivered to guests. Carbon fibre infrared units convert more of their input into usable radiant heat and lose nothing to combustion, so a 88 percent efficient carbon fibre tower such as the SereneLife unit delivers more usable warmth per kilowatt than any propane option. Over a full season, natural gas mounted units cost the least to run per hour of service because there is no fuel handling at all.
How many patio heaters do I need for my patio?
Use 40,000 BTU of gas output or 1,500W of electric as a target for every 100 sq ft of patio. That means one 50,000 BTU unit covers roughly 125 sq ft, and a 200 sq ft patio is better served by two units placed at opposite ends than by one large unit. On exposed rooftops, size up because heat loss is greater at height.
How long will a 20 lb propane tank last on a patio heater?
A 20 lb propane tank burns through in roughly five to six hours on a 50,000 BTU unit running at high output, so it may not last a full evening of continuous service at that setting. Running the control knob lower extends it considerably, and running heaters in one group rather than spread out also reduces consumption. Because these units weigh 40 to 60 pounds before the tank, plan the swap for two people between seatings.
Can you use a propane heater on a covered patio?
Yes, a propane heater works well on a covered or partially covered patio, and the cover actually helps by reducing wind loss. It must remain open on at least two sides, with the clearances to combustibles set out in the manual observed, and it must never be used in a fully enclosed space. Check the ceiling height and material against the required mounting distance before installation.
Do I need a permit to install a patio heater?
Requirements vary by jurisdiction. Propane heaters using a cylinder often need no permit, but permanently mounted natural gas units, a new gas line and hardwired 240V electrical circuits usually require one. An authority having jurisdiction or the fire marshal will want to see the heater listing mark, which is ETL, UL or CSA, plus evidence that clearances to combustibles are met. Confirm locally before ordering.
The Best Outdoor Heaters for Restaurants, Summarised
The best outdoor heaters for restaurants come down to one anchor and one supplement. Put a 46,000 to 50,000 BTU propane tower like the Amazon Basics model in the middle of a standard patio, then add mounted carbon infrared heat over the tables furthest away, or a couple of 1500W plug-in towers if the space is small.
That pairing solves the complaint every operator repeats: heat that is strong but uneven, leaving one side of the patio empty. Decide the fuel first, size at 40,000 BTU per 100 sq ft, and check the listing mark and clearances before anything is ordered.
