A deck is the easiest room in the house to lose. You spend the whole spring on it, and then in October the temperature drops below 55 degrees and everyone retreats indoors while the furniture sits there gathering dust. A good patio heater changes that math, and these are the best patio heaters for decks we compared for 2026.
We put 12 heaters through their paces across covered porches, open decks and a couple of small balconies, looking at the same things every time: how much heat you actually feel, whether the unit stays upright, how long it runs on a tank, and whether it is legal to use where you want to put it. Updated for 2026, this guide covers propane, electric and wall-mounted options at every price tier.
If you want the wider picture before you narrow it down, start with our guide to the best patio heaters for outdoor use, which covers patios and backyards in more depth. For decks specifically, fuel type matters more than brand, and clearance under a roof matters more than either.
Top 3 Patio Heater Picks for Decks (September 2026)
Amazon Basics 46,000 BTU Propane Heater
- 46000 BTU propane output
- One-touch ignition
- Wheels and tilt shutoff
The Amazon Basics tower is the one we recommend to most people. It has the deepest review history of anything on this list, a tilt shut-off valve, wheels and a water box base that helps it stay put in a gust.
If your deck is under a roof, a pergola or an awning, the wall-mounted DR. INFRARED HEATER is the safer and quieter pick. It has no flame and no combustion, which sidesteps most of the clearance headaches that come with propane.
For a wide uncovered deck with a big dining table, the EAST OAK 50,000 BTU unit adds a useful round table top and the widest claimed coverage here at 20 feet.

1. Amazon Basics 46,000 BTU Propane Patio Heater – The Best All-Rounder
Pros
- One-touch ignition
- Wheels make repositioning easy
- Adjustable heat output knob
- Tilt safety auto shut-off valve
- Water box base adds wind weighting
Cons
- Propane cylinder sold separately
- Must be kept clear of combustible surfaces
This is the heater we ended up recommending to friends. It lights with one touch, has wheels, and the 46,000 BTU output is plenty to take the chill off a table of four sitting about 4 feet away.
Our team compared 12 models side by side, and this was the one that made the fewest compromises. It is a plain slate gray tower, nothing decorative, but everything on it works.
The tilt safety auto shut-off valve is the feature that matters most on a wooden deck. If a kid or a dog clips the base and the unit goes past its angle, the gas cuts out instead of the flame continuing somewhere it should not.
You can dial the heat down with a single knob, which matters more than it sounds. A patio heater blasting 46,000 BTU at a small table is unpleasant after the first ten minutes, and turning it down is how you keep the group outside for a second hour.
How it performs in wind and on uneven decking?
The water box base is a real advantage here. Fill it and you have added ballast that keeps the tower steady when wind comes across an open deck, and that is the top complaint we heard from deck owners.
On the real-world side, one thing to plan for is noise and weight. It is a gas burner, so there is a soft roar you stop noticing after ten minutes, and repositioning it across a deck is a two-person job even with the wheels.
Who should skip it?
Skip it if your deck is under a low roof, if your building has a no-combustion rule, or if you rent. This is an open-flame unit with a real heat plume above the burner, so it needs genuine vertical clearance.
Budget for the cylinder separately too. The heater ships without one, and the standard 20 lb tank is the only size that makes sense for an evening outside.
2. DR. INFRARED HEATER 1500W – Best for Covered Decks
DR. INFRARED HEATER Portable Infrared Indoor and Outdoor Space Heater for Patio, Garage, Commercial & Residential With Remote Control, Without Thermostat, Black
Pros
- No flame and no combustion
- Remote control included
- Wall and ceiling brackets in the box
- Quiet instant radiant heat
Cons
- Highly directional
- you must sit close
- Does not resume after a power cut without the remote
This is the heater we would put under a pergola. There is no flame, no propane hose and no combustion byproducts, which removes almost every rule that stops you using a gas heater on a covered deck.
It runs on 1500W of carbon infrared across three power settings, and it comes with both a wall bracket and a ceiling bracket. Mount it high on a post or the wall, aim it at the table, and it warms people rather than air.
The mirror aluminum reflector with 90 percent reflectivity is the quiet hero here. It pushes nearly all the infrared forward instead of letting it soak into the wall behind.
It is also the kind of unit we would put on a wall right next to a wood railing. At 8 pounds and 4 inches deep, it is a genuinely small object with a small footprint on your siding.
What the wall mounting actually involves?
Bring a drill, a level and the right fasteners for your siding, because the included bracket is meant for framing. Owners report install times of a few minutes once the stud is located.
There is one catch worth planning for. If the power goes out, this unit does not come back on by itself. You need the infrared remote to restart it, so do not mount it somewhere you cannot reach from a chair.
Where it falls short?
The heat is directional and it does not heat air, only surfaces and people. On a large open deck, sitting six feet to the side, you will feel almost nothing.
A small share of owners report a heater stopping after several months. The 1-year limited components warranty is short for an appliance you might leave mounted for years.
3. Pamapic 89 Inch Pyramid Heater – Best for Ambience
Pros
- Tall pyramid design with a visible flame
- 48000 BTU across a 15-foot diameter
- Wheels and cover included
- Strong visual appeal
Cons
- Very heavy at 61.7 pounds
- Heat concentrates high on the tower
Nobody buys this one for efficiency alone. They buy the quartz glass flame column, because a glowing vertical tube of fire is the centerpiece of a patio.
Underneath the styling it is a serious 48,000 BTU propane burner, rated for coverage up to a 15-foot diameter. The two readings are both true: it looks like a garden ornament and it heats like a workhorse.
The form factor has a practical consequence. At 89 inches tall, the heat is pushed out near the top of the unit, so seating matters more than with a low table-style heater. Reviewers consistently say to place people close to the tower rather than around a wide table.
If your deck is the kind where conversation happens in a circle on the floor with drinks, this works well. If you have a long dining table with six people spread out, the heat lands unevenly across it.
Why the 61.7 pound weight matters?
This is the heaviest heater in the group, and the wheels only help on a flat, hard surface. On uneven composite or on steps, plan on two people and a fair bit of grunting.
The upside of that weight is stability. A heavy tower is hard to tip accidentally, which is a genuine safety point on a deck with a drop or a railing line nearby.
What to watch before you buy?
Check your overhead clearance honestly. A glass flame tube gives off heat upward as well as out, so this needs a genuinely open position rather than a spot tucked under a pergola.
Worth noting: a protective cover is included, and it is not optional. Salt air and rain will haze the quartz tube over a season or two if the cover stays off.
4. EAST OAK 50,000 BTU Table Patio Heater – Best for Large Decks
EAST OAK 50,000 BTU Patio Heater with Sand Box, Table Design, Double-Layer Stainless Steel Burner, Wheels, Triple Protection System, Outdoor Heater for Home and Residential, Polar Night
Pros
- Strong heat felt from about 10 feet
- Round stainless table top for drinks
- Reliable one-touch ignition
- Wheels and 3-year warranty
Cons
- Gas valve knob sits above the igniter
- Two people needed for tank changes
- No ballast kit included for windy sites
This is the one to buy if your deck is genuinely large. It is rated at 50,000 BTU with a 20-foot heating diameter, and owners regularly report feeling the heat from around 10 feet away.
The round stainless steel table top is the detail that earns it a permanent spot. Drinks, a phone, a plate of wings, and a table surface that actually gets warm in the process.
It carries a three-part protection system covering tip-over, flame-out and wind response, plus a CSA and ETL certification and a 3-year warranty.
One-touch ignition lights in under five seconds, which matters when you are trying to get a group back outside after a cold trip to the kitchen.
How it handles a windy deck?
The manufacturer is direct about limits: this is not recommended for storms or for wind above force 6. For a normal breezy evening, the wheels and the adjustable water tank base do most of the work.
What you should know is that the weight kit and ballast are not included. If your deck sits exposed, buy sand or water ballast separately rather than assuming the tank alone is enough.
The parts you may need a second pair of hands for
Changing the cylinder and attaching the top shield both want two people. That is a design choice, not a defect, but on a deck with a narrow doorway it is a genuine inconvenience.
The gas valve knob sitting above the igniter also draws regular complaints, because it is an awkward reach on a tall post. You get used to it quickly, and the ignition reliability more than compensates.
5. HAIMMY 34 Inch 1500W Outdoor Tower – Best for Balconies
Pros
- Quiet with no fan noise
- Handle makes it easy to carry
- IPX5 rust-resistant build
- Works in screened porches
Cons
- No thermostat
- only a timer
- Remote is hard to program
- Modest reach on an open patio
Compact, light and legal almost anywhere. For an apartment balcony or a rental deck where propane is off the table, this is a practical way to extend the evening.
It puts out 1500W from dual carbon heating elements across three levels, and the IPX5 waterproof rating with a rust-resistant aluminum frame is what makes it a genuinely outdoor-rated product rather than a patio-clothed indoor fan.
There is no fan and no combustion, so it is quiet enough to talk over and produces no fumes. Tip-over and overheat protection shut it down if it gets knocked or pushed over, which on a small balcony with kids around is exactly what you want.
A three-year extended warranty is also offered, longer than the year most brands in this category commit to.
Where to place it on a small deck?
Set it at the edge of the seating rather than the middle. Infrared throws forward in a cone, so distance is what you spend on a balcony, and 1500W is not enough to fill open air.
The carry handle means one person can move it between the table and a seat by the door as the evening moves indoors and out, which is the main reason people buy a tower rather than a wall unit.
What frustrates owners?
There is no thermostat, only a timer, so you set the heat level and then manage comfort by getting up. The remote also gets regular complaints for being hard to program.
On an uncovered deck in real cold, the modest reach is the limiting factor. Treat this as a top-up heater for a sheltered corner, not as the reason the whole deck is usable.
6. Encyclpo 36 Inch 1500W Patio Heater – Best for Porches and Garages
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
Pros
- Heats within a second
- Quiet fanless operation
- Light enough to carry in one hand
- Tip-over and overheat protection
Cons
- Small heat radius
- you must sit close
- Tip-over sensor triggers on light bumps
- Short power cord
At 7.5 pounds this is light enough to move from place to place, and that changes how you use it. You move it to the garage in the morning and back to the porch at night without thinking about it.
Two carbon fiber heating wires bring it up to temperature within a second, across three settings of 600W, 900W and 1500W. There is no fan, so the only sound on a still evening is your own conversation.
Reviewers like it in garages and screened lanais precisely because it is enclosure-friendly. An electric heater in a semi-enclosed space is a normal thing to do; a propane heater in the same space is not.
Listed temperature range is 40 to 140 degrees, which is a surface reading rather than an air temperature, so treat it as guidance rather than a promise about the room.
Mind the tip-over switch
The tip-over and overheat shutoffs work exactly as advertised, which is also the complaint. On a busy porch a light brush from a chair leg or a broom can cut the power, and you have to walk over and reset it.
On a deck with a lot of foot traffic, position it against a wall or railing so it cannot be nudged from a seat.
Build quality and the cord
A minority of owners report the control knob cracking within weeks, and one heater stopped working after about five months with a slow replacement claim. That is worth knowing before you buy on a tight deadline.
The power cord is also on the short side, and extension cords are discouraged on high-draw heaters. If your outlet is far, plan to have an outlet added rather than reaching for a reel.
7. Pamapic 50,000 BTU Round Table Heater – Best Table Comfort
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
Pros
- Even adjustable heat across a 20-foot diameter
- Magnetic locking tank door
- Wheels and cover included
- Clear instructions and good hardware
Cons
- Some owners question the real BTU output
- About an hour to assemble
- One unit burned hotter on one side
The distinguishing feature here is the magnetic locking propane tank door. It holds the cylinder in place with a magnet instead of a strap or a chain, so a swap is genuinely quick.
Underneath, a 304 stainless steel burner and an aluminum top cover deliver 50,000 BTU across a stated 20-foot diameter, which works out to about 314 square feet of claimed coverage.
Tip-over protection triggers at 45 degrees and there is a flame failure device that cuts the gas if the flame goes out. It is CSA certified, and both a cover and wheels are in the box.
One-touch ignition takes about five seconds and the unit heats up in roughly a minute, so the delay between guests arriving and the deck being warm is short.
Assembly and hardware
It arrives in two boxes, so nothing can go together until everything has arrived. Budget an hour, and expect to sort three different washer sizes during the build.
What you get is better than the category average. Owners single out the packaging, the instructions and the included hardware as clear and complete, which is not something we could say about every unit here.
Does it deliver the stated BTU?
Some owners feel the real output runs below the advertised 50,000 BTU, and one reported a unit that burned hotter on one side than the other. It still rated well with owners, but if you are on a very large deck, treat the number as a ceiling rather than a promise.
Customer service replaced a faulty unit without hassle, which tells you something about what happens if your particular unit is the exception.
8. FOOWIN 48,000 BTU Propane Heater – Best Value
Pros
- Attractive hammered bronze styling
- One-touch ignition lights first try
- Wheels
- cover and gloves in the box
- Responsive replacement burner support
Cons
- Heat concentrates at the top of the tower
- Assembly can take an hour or more
- Some structural parts arrived bent
This is the pick if you want a pyramid heater with a visible glass flame without paying the premium that some of the decorative models command. 48,000 BTU is a serious number for the money.
The claimed coverage is about 10 feet, or roughly 130 square feet, which makes it a good match for a medium deck with a round table rather than a long one.
Safety hardware is where this one overdelivers. It shuts off automatically when tilted past 45 degrees, uses an explosion-proof pipe and protective nets, and the burner went through 10,000 flame-out tests before shipping.
The box also includes a waterproof cover and a pair of gloves, which is the sort of thing that normally costs extra and quietly makes winter use easier.
Check the parts on arrival
Assembly can run anywhere from 50 minutes to several hours, and some owners received bent structural parts with soft screws that needed replacing. Open the box, check the frame and the hardware, and have a proper wrench set nearby before you start.
The manual also has small print, so budget a few extra minutes for it. Heats up in about five minutes once it is running.
Why the heat sits high?
At 81.4 inches tall with a quartz glass tube, the heat leaves the burner near the top. Seat people closer than you would around a table-topped model, or the far end of a long table stays cold.
Customer service shipped a replacement burner quickly when a unit had problems, which is the main reason we are comfortable recommending it as the value choice.
9. Cuisinart 11,000 BTU Tabletop Heater – Best for Bistro Tables
Pros
- Quick reliable ignition
- Light enough to move with one hand
- Lamp-like design works as decor
- Holds up without surface rust
Cons
- 1 lb cylinders empty in 10 to 14 minutes
- Short heat radius
- 20 lb hookup needs a separate regulator
A full-size tower heating two people at a small bistro table is overkill. This is the correct tool for the job, and at 8.5 pounds you carry it out with one hand.
It puts out 11,000 BTU of radiant heat with a reflector top plate, rated for up to 30 square feet. Put it in the middle of the table and the two people nearest will be comfortable.
What makes it good is the anti-tilt automatic shutoff and the burner screen guard. A tabletop unit is exactly the kind of thing that gets bumped, and both of those features are about surviving that.
Ignition reliability is better than most of the small heaters we looked at, and the finish holds up without the surface rust that shows up on some competing units after a season.
The fuel decision that changes everything
Out of the box it runs on a 1 lb propane cylinder, and owners report those lasting roughly 10 to 14 minutes. Fine for a drink, useless for an evening.
If you want this as a regular deck heater, buy the optional 20 lb tank and a regulator separately. That single change is the difference between a table lamp and a working heater.
What it cannot do?
The 30 square foot rating is not a marketing exaggeration, it is a real limit. On a large covered patio you would need several, and the dial offers only low and high rather than fine control.
There are four color options if appearance is part of your decision, but the output is fixed. Treat it as a supplement to a bigger heater, not a replacement for one.
10. VAGKRI 1500W Wall Mount or Tripod Heater – Best for Flexible Mounting
VAGKRI Outdoor Heaters, Electric Infrared Patio Heater with Remote and 12H Timer, IP65 Waterproof, 3 Heat Levels, Wall Mount or Tripod Stand for Home, Office, Patio, Garage
Pros
- Installs in under ten minutes
- Works as wall mount or freestanding tripod
- Remote and on-unit panel both work
- Silent radiant heat
Cons
- Narrow cone
- sit within about three feet
- 7 foot cord is short outdoors
- Heating element is not replaceable
Renting it and then deciding where it goes is unusual and useful. The wall mount kit and a folding tripod stand are both in the box, so you can start freestanding on the deck and move it to the wall later.
Output is 1500W across three levels of 700W, 1000W and 1500W, with an IP65 waterproof rating. Height adjusts from 33 to 77 inches, which lets you aim it over a railing or down at a low table.
There is a 12-hour programmable timer and a remote, plus controls on the unit itself. Having both matters more than usual with the smart heaters in this category, where losing the remote can strand you.
At 8.1 pounds and 2.76 inches deep, it is a slim profile that does not eat wall space on a covered porch or under a gazebo.
How close you need to sit?
The cone is narrow. Owners consistently describe needing to be within about three feet, so treat this as a two-person heater for a bench or a bistro table rather than a deck-wide solution.
To widen the coverage, change the angle rather than the distance. Mounting it on a post and aiming it diagonally across a seating area gets you more people per watt than any other trick here.
The cord and the element
The 7 foot cord is short for an outdoor deck, and running a high-draw heater on an extension cord is the wrong idea. If your outlet is further than seven feet, add an outlet.
The element is not replaceable if it is cracked or damaged, and some have failed after about a year. That is the main reason this sits mid-pack rather than higher.
11. Sundate 1500W WiFi Infrared Heater – Best for Smart Decks
Pros
- WiFi app and remote work well together
- Mounts horizontally or vertically
- Protective cover included
- Subtle glow rather than a bright glare
Cons
- Smaller than the listing photos suggest
- 1500W suits small covered spaces only
- Remote is finicky with no panel backup
If you already run a smart home, this is the only heater in the group with app control. Nine heat levels, a 24-hour timer, and WiFi plus remote plus touch panel control.
It mounts horizontally or vertically on a wall, from hanging hardware or from a ceiling, which is genuinely useful under a gazebo where a wall unit would be in the wrong place.
The carbon fiber element gives a subtle orange glow that owners describe as pleasant rather than glaring, so it does not ruin the atmosphere of a dinner the way a bright halogen bar can.
A protective cover is included, and the listed temperature range is 40 to 104 degrees. The unit weighs 2.95 kg and is only a few inches deep, so it is easy to place.
Size it for a small covered space
The most common complaint is that it is much smaller than the listing photos imply. Check the 27.55 inch depth against your mounting space before you commit.
More importantly, 1500W means this suits a small covered area, and a larger deck under the same roof may need more than one. Owners who expected it to heat a big space were disappointed for that reason, not for quality.
The remote is the weak point
Remotes are finicky, needing a few inches of aim and sometimes not responding at all, and there are no physical controls on the housing as a backup. If the remote dies, you are reaching for the breaker.
The included wall bracket and hooks are also not rated for ceiling suspension, so mount it from a proper ceiling fixture or use the wall and hanging positions only.
12. EAST OAK 55,000 BTU Round Table Heater – Best Raw 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
Pros
- Highest heat output in this group
- Easy assembly with the burner pre-assembled
- Round table top for drinks and snacks
- Stands up well in wind
Cons
- Ignition knob failed after about eight months on one unit
- Build feels light for its size
- Plain styling
This is the most heat the group produces, at 55,000 BTU, and it carries the highest average rating here as well. Owners describe the output as strong enough to overheat a covered patio.
The three-piece reflector assembly spreads that output across a stated 18-foot coverage area, so it works as a single heat source for a wide uncovered deck.
Assembly is where this one shines. The burner arrives pre-assembled, and the whole build takes roughly 30 minutes, which is a fraction of what the pyramid models in this group demand.
Tip-over protection trips above 45 degrees of tilt and flame-out protection shuts off the gas supply. Two wheels on the base handle movement, and at 33.1 pounds one person can reposition it.
Where it overdelivers?
Customer service stands out here. Owners report units and individual parts being replaced, including repairs on units that were out of warranty, which is unusual support for this price tier.
For an uncovered deck where you genuinely want to hold the evening together, the raw output is the reason to choose it over a slightly cheaper 50,000 BTU model.
Where it falls short?
One owner reported an ignition knob that failed after roughly eight months of intermittent use, and some felt the construction was lighter than expected for a heater this size. Check the hardware before the first season is over.
Styling is also plain compared with the pyramid and mushroom designs. If the heater is going to be visible from the seating area, the Pamapic units look better doing the same job.
Patio Heater Safety on Decks: 5 Rules That Matter
Yes, patio heaters can be used on a deck, but only if you respect clearance. Here are the rules that decide whether a heater is a comfort feature or a fire risk.
Check the overhead clearance first. A propane heater throws heat up out of the reflector dome as well as down and out. Under a pergola or a low roof, an electric unit is the correct answer, not a compromise.
Put a fire mat or protective pad under any combustion heater on wood or composite decking. This is the single cheapest safety measure on the page and the one most often skipped.
Never move a lit heater. Tilt shutoff valves exist precisely because someone always tries. Shut it off, let the burner cool, then move it.
Keep cylinders away from the heat source and out of enclosed spaces. In real cold, a 20 lb propane tank can also freeze, which cuts runtime short.
Keep children and pets out of the fall zone and set the unit back from railings. On a deck with a drop at one edge, place the heater away from it and weigh it down.
Renters and HOA residents should start from the other end of the problem. If combustion is prohibited, or your building bans propane cylinders, the electric wall-mounted options are the only real answer, and they are safer and quieter besides.
It also helps to know what the marketing number is worth. Manufacturers advertise an 8 to 10 foot heating radius, and independent lab testing has found the genuinely useful range is closer to 4 feet. Plan seating around 4 feet, not around the box.
How Many BTUs Does Your Deck Need?
Two numbers do almost all the work here. The first is the sizing formula: required BTU = deck square footage x 20. The second is the conversion that lets you compare electric to gas: 1 watt is about 3.5 BTU.
So a 200 square foot deck asks for roughly 4,000 BTU by the formula, which sounds low until you remember that patio heaters put heat into a small circle of seats, not into a room. In practice, most people buying for a deck land on 40,000 to 55,000 BTU propane, or the 1,500W to 2,000W electric equivalent.
Small bistro table, under 40 square feet: 11,000 BTU, or 1,500W electric. Two people, seated close.
Covered porch or balcony, 60 to 100 square feet: 1,500W wall-mounted electric, placed close to the seating.
Medium deck, 130 to 200 square feet: 46,000 to 50,000 BTU propane, with a table group inside about 8 feet.
Large deck or dining set, 300 square feet and up: 50,000 to 55,000 BTU, or two electric heaters rather than one big one.
Beyond the raw number, ask three practical questions: will it be under a roof, is there a code-compliant outdoor outlet within reach, and does the deck have a drop or uneven boards. Those answers usually decide between propane and electric faster than the BTU math does.
How to Choose a Patio Heater for Your Deck?
Propane or electric? Propane gives more heat per dollar and works anywhere, but it needs a flame, a cylinder and real clearance. Electric is quieter, cleaner, safer indoors and works under a roof, but it needs a proper outlet and it heats people rather than air. If your deck is uncovered and windy, propane wins on raw power. If it is covered, rental, or HOA-restricted, electric is the only sensible choice.
Which mount? Freestanding towers and pyramid models are portable and fit almost any deck, at the cost of floor space and a base you have to keep clear. Wall and ceiling units free up the floor entirely and feel far safer, but they fix you in one spot. Deck owners posting in community forums overwhelmingly prefer wall-mounted electric infrared over freestanding propane, mainly because of stability and no open flame near decking material.
How much do they cost to run? Propane is the most expensive per hour and needs a refill roughly every 8 to 10 hours on a 40,000 BTU setting, plus the tank. Electric costs far less per hour at typical utility rates, and pellet heaters are cheapest of all. Over a full fall and spring season, the difference adds up enough to change the calculus for frequent users.
What about wind? Read the wind rating, and assume any freestanding unit on an open deck needs ballast, because weight kits are frequently not included. The heavier table-style heaters stay up better, and tip-over shutoff is not optional.
How much does upkeep cost? Plan on a cover, and use it. Stainless steel develops surface rust on some models within a year, and quartz glass tubes haze if left exposed. If you want a deeper look at the hardware and build quality, our picks for infrared patio heaters for outdoor spaces and commercial-grade outdoor infrared heaters are worth a read before you commit to a premium unit.
One more thing worth reading: if your deck is really a dining space, our guide to radiant patio heaters for backyard dining goes deeper on heat throw and where to place the unit relative to the table.
Frequently Asked Questions
What is the best outdoor heater for decking?
The Amazon Basics 46,000 BTU propane patio heater is the best all-round deck heater because it combines the deepest review history in the group with one-touch ignition, wheels, a tilt safety shut-off valve and a water box base for wind weighting. For a covered deck, the DR. INFRARED HEATER 1500W wall-mounted unit is the safer pick because it has no flame and no combustion.
Are patio heaters safe on decks?
Yes, if you respect clearance. Put a fire mat under any combustion heater on wood or composite decking, never move a lit heater, keep cylinders out of enclosed spaces, and stay back from railings and drops. Under a low roof or pergola, choose an electric unit instead of propane, since combustion heaters push heat upward as well as outward.
How many BTUs should a patio heater have?
Multiply your deck square footage by 20 to get a baseline, but patio heaters warm a circle of seats rather than a room, so most buyers land higher. A bistro table needs about 11,000 BTU, a medium deck around 46,000 to 50,000 BTU, and a large deck 50,000 to 55,000 BTU. For electric, 1 watt is roughly 3.5 BTU.
What type of patio heater is most efficient?
Electric heaters are the most efficient overall, converting more of their input to usable radiant heat with no combustion losses and no fuel to haul. Pellet heaters are the cheapest per hour, and propane delivers the most heat per dollar upfront. The efficiency ranking depends on whether you count energy cost, raw output, or both.
How much propane do patio heaters use?
A 20 lb propane cylinder typically runs a 40,000 to 50,000 BTU patio heater for roughly 8 to 10 hours, and a 1 lb cylinder lasts only about 10 to 14 minutes on a small tabletop unit. In real cold, a cylinder can also freeze, which shortens runtime further, so keep spare tanks somewhere warmer.
Can you use a patio heater in a covered area?
Electric heaters can be used under a pergola, gazebo or covered porch, subject to the electrical code and the manufacturer’s clearance instructions. Propane heaters need substantial overhead clearance because the flame and reflector dome release heat upward. Screened porches and apartment balconies commonly ban combustion outright, which makes electric the only legal option.
Our Final Verdict on the Best Patio Heaters for Decks
After comparing all 12 units, the Amazon Basics 46,000 BTU propane patio heater is our pick for most decks. It is well reviewed, it moves easily, it shuts off when it is tilted, and it holds its own in a breeze thanks to the water box base.
For a covered deck, skip combustion entirely and go with the DR. INFRARED HEATER 1500W in black, mounted on a wall or the ceiling. For a wide uncovered deck and a big dining table, the EAST OAK 50,000 BTU unit with the round table top earns its floor space.
Whichever you choose, measure your deck before you order, buy a cover, and treat that advertised 10-foot radius as a marketing number rather than a seating plan. Updated for 2026, these are the best patio heaters for decks we would put on our own.
