6 Best Patio Heaters Under $100 in 2026
Six budget patio heaters compared on wattage, coverage, heat settings and safety cutoffs, so you can warm a porch, garage or deck without overspending.
At a Glance
At the lowest budget tier, a patio heater is a very different product from the tall propane towers you see at restaurants. Almost every pick here is a plug-in 1500W fan-forced ceramic heater, with one entry-level standing gas heater included as the exception. That matters, because these heaters warm the air near you rather than blasting radiant heat across an open yard, and the right choice depends on how enclosed your space really is.
We evaluated six distinct models based on product specs and buyer feedback, skipping the duplicate listings that appear under several titles. We looked at wattage and heat settings, claimed coverage area, how fast the heating element reaches warmth, oscillation or angle adjustment, and the safety cutoffs each maker lists. Where a spec was not stated on the listing, we left it out rather than guess.
The honest framing at this budget is simple: these heaters shine on screened porches, in garages, in greenhouses and on covered decks with a nearby outlet. They are not a substitute for a gas heater in a windy, fully open patio. Use the sections below to match the right model to your space, and to see what spending more would actually add.
6 Criteria to Look For Before Buying a Patio Heaters Under $100
Key buying criteria so you get the right fit the first time.
Electric versus gas at this budget
The first decision is whether you need a plug-in fan heater or a gas tower, because they solve different problems. Electric 1500W units warm the air near them and need an outlet, which fits porches, garages and greenhouses. A gas heater such as the BALI OUTDOORS at 40,000 BTU is the only pick here that makes sense in a wide open yard. Before buying, measure the distance from your seating to the nearest outlet and decide whether your space has walls or a roof to hold warm air.
Wattage and the 1500W ceiling
Household circuits cap most plug-in heaters at about 1500W, so every electric pick here sits at that level and none will out-muscle another on raw wattage. What differs is how that power is delivered through fans, modes and oscillation. The HETRAROOT adds four modes and 70 degree sweep, while the Joanolga and SEEYANG offer three modes starting at 20W and 25W. Do not pay extra for a bigger wattage number, because above 1500W you are into gas or hardwired territory.
Claimed coverage and real coverage
Listings quote coverage as a square footage, but a fan heater only hits that number in a mostly enclosed room. The HETRAROOT claims 350 square feet, while both Buyplus models claim 200 square feet. As a rule of thumb, cut any claimed figure roughly in half for a screened porch and by more for open air. If your seating zone is a few chairs within about ten feet, any of these models is plenty.
Heat-up speed and modes
PTC ceramic elements reach warmth in seconds, and the listings range from one second on the HETRAROOT to two on the SEEYANG and second Buyplus, and three on the standard Buyplus and Joanolga. The difference is barely noticeable in practice, so do not weigh it heavily. Modes matter more: a 25W or 20W low setting, like the SEEYANG and Joanolga offer, lets you hold gentle warmth without running full power. Pick a model with at least three steps if you will use it for long sessions.
Safety cutoffs to confirm
Overheat protection and tip-over shutoff are the two features worth confirming on any heater you leave running. The Buyplus models list a self-resetting breaker that cuts power when the unit gets too hot, and the second listing mentions tip-over protection as well. Gas heaters add flame-out protection, and the BALI OUTDOORS listing names both a flame failure device and an auto shut off tilt device. Never leave any heater running unattended near fabric, and read the clearance distances in the manual before you set it up.
Weather exposure and placement
Budget plug-in heaters are generally designed for sheltered use, even when the title says outdoor, so keep them out of direct rain and standing water. A covered porch, garage or greenhouse is the right home for the HETRAROOT, SEEYANG, Buyplus and Joanolga. The BALI OUTDOORS is the one built for open-air placement, though it still needs overhead clearance for its 86.7 inch height. Always use an outdoor-rated extension cord if the outlet is far, and keep the plug off wet ground.
6 Best Patio Heaters Under $100 in 2026
HETRAROOT 24 Inch 1500W PTC Patio Heater
About this pick
The HETRAROOT is a 24 inch tall 1500W heater built around PTC ceramic technology, and the listing says it reaches warmth in about one second. It pairs the element with an upgraded DC motor and a reworked impeller that the maker says moves 120 percent more airflow than a standard unit. Four heating modes give you more steps than the usual low and high pair.
The feature that sets it apart in this lineup is the 70 degree oscillating head, which spreads warm air across a seating area instead of aiming one stream at one chair. The listing claims coverage of up to 350 square feet, the largest figure among the plug-in picks here, though a fan heater only reaches that in a reasonably enclosed space. In open air you should expect a smaller comfortable zone, and the heat is concentrated close to the unit.
Ownership is straightforward: plug it into a standard outlet, pick a mode and let it oscillate. Compared with the Buyplus 1500W at a claimed 200 square feet, the HETRAROOT claims nearly twice the coverage and adds oscillation, which the Buyplus does not offer. Compared with the BALI OUTDOORS at 40,000 BTU, it cannot match gas output, but it needs no fuel and no tank swaps.
Best for: A screened porch or covered deck where you want warm air spread across a whole seating group.
Check price on AmazonSpecs
- Wattage: 1500W
- Technology: PTC ceramic
- Heating modes: 4
- Oscillation: 70 degrees
- Claimed coverage: 350 sq ft
Pros
- +70 degree oscillation spreads heat across the seating area
- +Four heating modes give finer control than low and high
- +Largest claimed coverage of the plug-in picks at 350 sq ft
- +PTC ceramic element reaches warmth within seconds
Cons
- −Fan heat is strongly affected by breeze in open air
- −Needs an outlet within cord reach of the seating
BALI OUTDOORS 40,000 BTU Standing Gas Patio Heater
About this pick
This is the one true standing patio heater in the lineup, an umbrella style tower rated at 40,000 BTU and standing 86.7 inches tall with a 32.4 inch diameter reflector. The umbrella shape is meant to reflect heat downward over a seating area, which is how restaurant heaters warm open patios. An adjustable knob controls the flame, though the maker notes the output is fixed at a set maximum.
The tradeoff is size and setup. At nearly seven and a half feet tall it needs real overhead clearance, so it does not belong under a low porch roof or awning, and it needs a propane supply you must manage. The wheel assembly, with textured wheels rather than smooth ones, makes it easier to roll into position, but a tall gas heater is still something you place carefully and keep away from foot traffic.
If your patio is wide open and breezy, this is the pick that can actually make a difference, because 40,000 BTU dwarfs the 1500W electric picks. Compared with the HETRAROOT, you gain reach and open-air capability but lose plug-and-play convenience and indoor-adjacent use. The listing names both an auto shut off tilt device and a flame failure device, and says the hose and regulator are included but the gas cylinder is not, so budget for a tank.
Best for: A wide open patio or backyard where plug-in electric heat would simply blow away.
Check price on AmazonSpecs
- Heat output: 40,000 BTU
- Dimensions: 32.4 in dia x 86.7 in tall
- Style: Umbrella reflector
- Mobility: Wheel assembly
Pros
- +40,000 BTU output is far beyond any electric pick here
- +Umbrella reflector pushes heat down over the seating
- +Wheel assembly makes repositioning manageable
- +Adjustable knob lets you tune the flame
Cons
- −86.7 inch height needs generous overhead clearance
- −Requires propane supply and outdoor-only placement
SEEYANG 1500W Portable Electric Patio Heater
About this pick
The SEEYANG combines a 1500W PTC ceramic element with a 2600 RPM high speed fan, and the listing says it produces hot air in about two seconds. Three output modes cover natural air at 25W, low heat at 750W and high heat at 1500W. That natural air mode is useful because the same unit doubles as a simple fan in warmer weather.
The maker also stresses quiet operation, positioning it for peaceful nights on a porch or in a greenhouse. A fast, high RPM fan is a good thing when you want heat quickly, but it is also where noise comes from, so treat the quiet claim as a maker statement and check buyer feedback on the product page if you will sit near it.
This is a good value pick if you want proven simplicity rather than extra features. Next to the Joanolga, which also offers three levels, the SEEYANG heats a second faster by its listing and has a lower fan-only setting at 25W compared with 20W on the Joanolga. Next to the HETRAROOT, it has no oscillation, so you aim it rather than sweep it.
Best for: Someone who wants quick warmth in a small enclosed spot and a fan mode for the warm season.
Check price on AmazonSpecs
- Wattage: 1500W
- Heat-up time: 2 seconds
- Fan speed: 2600 RPM
- Modes: 25W / 750W / 1500W
Pros
- +Reaches hot air in about two seconds by the listing
- +Three modes including a 25W natural air setting
- +2600 RPM fan moves warmth quickly
- +Doubles as a simple fan outside heating season
Cons
- −No oscillation, so heat stays aimed in one direction
- −Coverage depends on an enclosed or sheltered space
Buyplus 1500W Portable Outdoor Heater, 3S Heat-Up
About this pick
The standard Buyplus is a 1500W PTC ceramic heater that the listing says heats up in three seconds and warms a space of up to 200 square feet. Its three modes are fan only, 750W and 1500W, selected by a simple control. A self-resetting heat breaker cuts power when the internal temperature gets too high and restores it after cooling.
The non-slip base is a small but practical detail, since a fan heater that creeps across a smooth garage floor is annoying. It is clearly designed around garages and workshops, and the product name even calls it a garage heater. On a patio it works best in sheltered corners rather than open seating areas.
Compared with the HETRAROOT at a claimed 350 square feet, the Buyplus claims 200, so it suits smaller spaces. Compared with the SEEYANG at two seconds, its three second heat-up is a touch slower on paper, though in practice that difference is hard to feel. It is a dependable, no-frills choice that lacks oscillation, which keeps it simple to operate.
Best for: Garages, workshops and small sheltered corners where simple controls matter most.
Check price on AmazonSpecs
- Wattage: 1500W
- Modes: Fan / 750W / 1500W
- Claimed coverage: 200 sq ft
- Heat-up time: 3 seconds
- Safety: Self-resetting overheat breaker
Pros
- +Self-resetting overheat breaker adds a safety layer
- +Non-slip base keeps it from creeping on smooth floors
- +Fan only mode doubles as a basic fan
- +Simple three mode control is easy to operate
Cons
- −Claimed 200 sq ft is smaller than the HETRAROOT claim
- −No oscillation, so it heats one direction
Joanolga 1500W Electric Greenhouse Heater
About this pick
The Joanolga offers three power modes at 20W low, 750W medium and 1500W high, using a PTC ceramic element that the listing says warms up in about three seconds. The maker markets it for greenhouses as well as patios, and it includes overheat protection. Its bright yellow finish is a distinctive choice that makes it easy to spot and hard to trip over in a dim space.
The listing claims it can warm spaces up to 160 square feet, which is smaller than the Buyplus claim of 200 and the HETRAROOT claim of 350. That makes it a small-space heater, best for a bench, nook or shed. The 20W low setting is the lowest heat level among the heaters here, which suits keeping a greenhouse bench or a small nook just above chilly.
Compared with the SEEYANG, it loses a second on heat-up and a few watts at the bottom setting, but it also has a gentler floor. Compared with the HETRAROOT, it has fewer modes and no oscillation. It is a reasonable alternative if the color or the very low setting appeals to you.
Best for: A small greenhouse, potting bench or shed that needs gentle, steady warmth.
Check price on AmazonSpecs
- Wattage: 1500W
- Modes: 20W / 750W / 1500W
- Heat-up time: 3 seconds
- Finish: Yellow
Pros
- +Lowest setting of the lineup at 20W for gentle warmth
- +Three clear power modes up to 1500W
- +Overheat protection included
- +Bright finish is easy to see in a dim space
Cons
- −160 sq ft claim limits it to small spaces
- −No oscillation or angle adjustment listed
Buyplus 1500W Heater with Adjustable Angle, 2S Heat-Up
About this pick
This second Buyplus model adds an adjustable heating angle to the same basic 1500W PTC ceramic recipe, and the listing says it reaches warmth in two seconds instead of three. It keeps the three modes of fan only, 750W and 1500W, and the same claimed 200 square foot coverage and overheat protection. The angle adjustment lets you tilt the output toward a chair or a workbench rather than only straight ahead.
The listing text is a little inconsistent about the exact angle range, so we would check the product page before relying on a specific degree figure. What matters in practice is that you can aim the heat upward or downward, which helps when you are seated low on a bench or standing at a table. It is still a fan heater and still best in sheltered spots.
Compared with the standard Buyplus at three seconds, this version heats a second faster on paper and adds aiming. Compared with the HETRAROOT, it sweeps nothing but gives you manual control over direction. If you will mostly sit in one spot, angle adjustment is arguably more useful than oscillation, because the heat goes where you are.
Best for: Heating one chair, bench or workstation where you want to aim the warmth.
Check price on AmazonSpecs
- Wattage: 1500W
- Modes: Fan / 750W / 1500W
- Heat-up time: 2 seconds
- Claimed coverage: 200 sq ft
- Aiming: Adjustable angle
Pros
- +Adjustable angle lets you aim heat at where you sit
- +Heats in about two seconds by the listing
- +Same fan, 750W and 1500W modes as the standard Buyplus
- +Overheat protection included
Cons
- −Listing is unclear about the exact angle range
- −Claimed coverage of 200 sq ft is modest
How We Evaluated These Patio Heaters Under $100
Each pick was assessed across 5 criteria weighted for real-world use.
Heat output and power delivery
We compared stated wattage and BTU on each listing and noted how the heat is delivered. Five picks are 1500W PTC ceramic fan heaters, while the BALI OUTDOORS is a 40,000 BTU gas tower. We gave extra credit to models with more modes, such as the HETRAROOT with four, because finer control makes a heater usable for longer sessions.
Claimed coverage and spread
We looked at the coverage claim and how the heat is directed. The HETRAROOT leads with a claimed 350 square feet and 70 degree oscillation, while the Buyplus pair claim 200 square feet. We discounted claims that rely on an enclosed room, and we rewarded oscillation or adjustable angle because they help one heater serve a group.
Safety features listed
We reviewed the safety cutoffs each maker lists, including self-resetting overheat breakers on the Buyplus models and overheat protection on the Joanolga. Gas heaters need flame-out protection too, and the BALI OUTDOORS lists a flame failure device and a tilt shutoff. The SEEYANG listing also states ETL certification, and we did not assume any certification that was not stated.
Ease of setup and use
Simple controls and plug-and-go setup matter at this budget. The electric picks need nothing more than an outlet, while the gas tower needs propane and careful placement. We favored the non-slip base on the standard Buyplus and the angle adjustment on the second Buyplus as practical touches.
Value and lineup positioning
We positioned the lineup so each pick leads on one thing: the HETRAROOT on coverage and oscillation, the BALI OUTDOORS on open-air gas heat, the SEEYANG on fast heat-up and quiet claims, the Buyplus models on garage simplicity and aiming, and the Joanolga on the lowest setting. Prices change often, so we judged value by features rather than quoting figures.
How to Choose the Right Patio Heaters Under $100
By Space Type
The kind of space you are heating decides almost everything at this budget.
| Your space | Best pick | Why |
|---|---|---|
| Screened porch or covered deck with outlet | HETRAROOT 24 Inch 1500W PTC Patio Heater | 70 degree oscillation and 350 sq ft claim spread heat across seating |
| Wide open backyard patio | BALI OUTDOORS 40,000 BTU Standing Gas Patio Heater | Only pick with gas output that works in open air |
| Garage or workshop | Buyplus 1500W Portable Outdoor Heater, 3S Heat-Up | Non-slip base and overheat breaker suit a work area |
| Greenhouse or potting shed | Joanolga 1500W Electric Greenhouse Heater | 20W low setting holds gentle warmth |
| One chair or workbench to warm | Buyplus 1500W Heater with Adjustable Angle, 2S Heat-Up | Aimable heat goes where you sit |
If a space has no walls or roof, a fan heater will disappoint you, so be honest about how enclosed your area is.
By Budget
Even within a tight budget, the picks fall into relative tiers.
| Tier | Pick | What you get |
|---|---|---|
| Entry | Buyplus 1500W Portable Outdoor Heater, 3S Heat-Up | Basic fan, 750W and 1500W modes with an overheat breaker |
| Entry | Joanolga 1500W Electric Greenhouse Heater | Three modes with a gentle 20W floor |
| Mid | SEEYANG 1500W Portable Electric Patio Heater | Faster heat-up and a 2600 RPM fan |
| Mid | Buyplus 1500W Heater with Adjustable Angle, 2S Heat-Up | Aimable output and a two second heat-up |
| Top of tier | HETRAROOT 24 Inch 1500W PTC Patio Heater | Four modes, oscillation and the biggest coverage claim |
| Top of tier | BALI OUTDOORS 40,000 BTU Standing Gas Patio Heater | Real open-air heat, with propane to manage |
Spending a little more generally adds sturdier construction, remote controls, infrared heating and better weather ratings, which are covered in the next budget tier.
Electric Fan Heat vs Gas Radiant Heat
These two heat styles behave differently once you sit down outside.
Electric fan heat
A PTC ceramic element heats air that a fan pushes toward you, so warmth is strongest close to the unit and drifts in wind. This is the style of the HETRAROOT at 1500W, the SEEYANG at 1500W, both Buyplus models and the Joanolga. They suit enclosed or semi-enclosed spaces, plug into a standard outlet and need no fuel. Pick this if your area has walls or a roof.
Gas radiant heat
A gas tower such as the BALI OUTDOORS at 40,000 BTU burns propane and uses an umbrella reflector to push heat down over a seating circle. It works in open air because the warmth does not rely on a fan, but it needs fuel, overhead clearance for its 86.7 inch height and careful placement. Pick this if you have a wide open patio and are comfortable managing propane.
Choose electric for sheltered, convenient warmth, and gas only when your space is truly open.
By Control Style
How much control you want over the heat is the second decision axis.
| Control priority | Pick | Detail |
|---|---|---|
| Most heat settings | HETRAROOT 24 Inch 1500W PTC Patio Heater | Four heating modes plus 70 degree oscillation |
| Lowest gentle setting | SEEYANG 1500W Portable Electric Patio Heater | 25W natural air mode, then 750W and 1500W |
| Gentlest heat floor | Joanolga 1500W Electric Greenhouse Heater | 20W low setting before 750W and 1500W |
| Aim without moving the unit | Buyplus 1500W Heater with Adjustable Angle, 2S Heat-Up | Adjustable heating angle |
| Simplest controls | Buyplus 1500W Portable Outdoor Heater, 3S Heat-Up | Fan only, 750W and 1500W |
More modes sound better, but a heater with three clear settings is often easier to live with.
For a Covered Porch Specifically
A covered porch is the most common place these heaters end up, and it has its own rules.
Look for
Look for oscillation or aimable heat so one unit can cover several chairs, a stated coverage figure so you can size it, and a base that stays put. Check cord reach to the nearest outlet, and make sure you have clearance from cushions and curtains. A porch with a ceiling and at least one wall holds the warm air best.
In this comparison
The HETRAROOT at 350 square feet claimed and 70 degree oscillation is the strongest porch fit, followed by the SEEYANG for fast heat-up. The Buyplus with adjustable angle works well if you sit in one spot. The BALI OUTDOORS is too tall for most low porch ceilings at 86.7 inches.
Keep any heater at least a few feet from flammable fabrics and follow the manual clearances.
When to Spend More
Moving up a budget tier adds specific features, so decide if you need them.
| Spend more if | Save if |
|---|---|
| You want gas heat for a big open patio, because the BALI OUTDOORS only gets you started on 40,000 BTU | Your space is sheltered and a 1500W HETRAROOT is enough |
| You want infrared heat that works in breeze, which these fan models cannot provide | You sit within a few feet and the SEEYANG or Buyplus will warm you |
| You want a remote control or timer, which none of these list | You are happy turning the knob by hand |
| You want a higher weather rating than these sheltered-use heaters carry | You keep the heater under a roof, like with the Joanolga in a greenhouse |
| You need to heat more than a few chairs with one unit | You only heat one seat, where the adjustable angle Buyplus suffices |
Moving up the budget ladder mostly buys gas output, infrared heat and remote features, not more wattage from a plug-in unit.
Frequently Asked Questions
Will a 1500W electric patio heater warm an open patio?
Not well. A 1500W fan heater warms the air close to the unit, and wind carries that warmth away. In a screened porch, garage or covered deck it can be very effective. For a wide open yard, a gas heater like the BALI OUTDOORS at 40,000 BTU is the more realistic choice.
Which of these should I pick if I can only buy one?
For most people with a covered or semi-enclosed space, the HETRAROOT 24 Inch is the best all-around pick thanks to four modes, 70 degree oscillation and the biggest coverage claim. If your patio is completely open, choose the BALI OUTDOORS instead. For a garage, the standard Buyplus is a simple and sturdy option.
How much space can one of these really heat?
Treat listing claims as best-case numbers. The HETRAROOT claims 350 square feet and the Buyplus models claim 200 square feet, but those figures assume an enclosed room. On a screened porch, plan on a comfortable zone of a few chairs within about ten feet of the heater.
Are these heaters safe to leave running?
They include safety features like overheat protection, and the Buyplus listings mention a self-resetting breaker, but no heater should run unattended. Keep a few feet of clearance from curtains, cushions and paper. Check the manual for exact distances and never cover the vents.
Do cheap patio heaters last?
Simple PTC ceramic heaters have few moving parts besides the fan, so the fan motor is the usual wear point. Keeping the unit dry, dusting the vents and storing it indoors in the off season will extend its life. Gas towers like the BALI OUTDOORS need periodic checks of hoses and connections as well.
Is a garage heater the same as a patio heater?
The technology is the same. Several of these, including both Buyplus models, are marketed as garage heaters and also called patio heaters. The label matters less than whether the space is sheltered and whether you can place the heater safely.
Can I use these indoors too?
Electric fan heaters are designed for use in enclosed spaces like garages, but you should read the listing and manual for the intended use of each model. Never use the gas BALI OUTDOORS indoors, because burning fuel creates carbon monoxide and needs open-air ventilation. Even the electric models should stay dry and be kept clear of flammable material.
