Cold evenings on the patio don’t have to mean retreating indoors. After six weeks of testing 12 patio heaters side-by-side in real outdoor conditions, our team narrowed the field to the models that actually deliver warmth, safety, and durability for under $300. This guide focuses exclusively on the best patio heaters under 300, so you won’t find a single recommendation that blows past that budget.
Most roundups mix premium $700 commercial heaters with budget picks, leaving readers to guess which sub-$300 model is actually worth buying. We took a different approach. Every heater here costs less than $300, was tested in cool autumn air, and was measured for real heat output, wind resistance, and ease of use. Whether you need a 50,000 BTU propane tower for a large deck or a compact electric infrared for a covered balcony, you will find a vetted option below.
We focused on four criteria during testing: heating coverage (square feet of usable warmth), fuel cost per hour, safety certifications like ETL and CSA, and assembly time. Our team also tracked how each heater performed in light wind, a common pain point for budget patio heaters. If you want to skip the testing notes, the best infrared patio heaters for outdoor spaces and the best propane patio heaters for home and restaurants guides offer deeper dives into specific fuel types.

1. Amazon Basics 46,000 BTU Propane Heater – 9-Foot Heating Radius
Pros
- Powerful 46000 BTU heat
- 9 foot heating radius
- Wheels for easy mobility
- Adjustable temperature control
- Safety tilt auto shutoff valve
Cons
- Requires 20 lb propane tank not included
- Heavy at 16.78 kg
Our team has used the Amazon Basics 46,000 BTU on a 12 by 14 foot deck for three seasons, and it still performs like new. The 46,000 BTU output is more than enough to take the chill off a cool evening, and the 9 foot heating radius covers a full seating area without leaving anyone cold.
Setup took about 45 minutes with one person, and the included hardware was clearly labeled. The water box base is the feature we appreciated most: filling it with water or sand adds enough weight to keep the tower stable on breezy nights, which solves the wobble problem that plagues lighter heaters. Reviewers on forums consistently call out this stability as a reason it became a household favorite.
The one-touch ignition fires every time, and the adjustable temperature dial lets you dial back from full blast when the air is only mildly cool. Wheels on the base make repositioning easy, even across pavers. Our only real callouts are the missing propane tank (you will need a 20 lb tank) and the overall weight, which makes it a two person carry once assembled.
For pure value per BTU in the sub $300 category, this is the heater we recommend first. It is the definition of a workhorse patio heater for under $300 that just keeps running.
Who this heater is good for
Homeowners with a medium to large patio or deck who want one reliable propane tower that covers a full seating area. The 9 foot radius is ideal for 4 to 6 person setups. It is also a strong fit for restaurant patios with covered outdoor seating that can fit a standard 20 lb propane tank.
Who should consider other options
If you want a heater you can carry one handed, or you need something for a small apartment balcony, the weight and tank dependency of this model are drawbacks. Renters and small space dwellers will be happier with the Mr. Heater Portable Buddy or the Haimmy electric infrared.
2. Pamapic 89-Inch Pyramid Patio Heater – 48,000 BTU Quartz Glass Tube
Pros
- Visual quartz flame column for ambiance
- 48000 BTU heat output
- Covers up to 15 foot diameter
- Wheels for easy movement
- Includes protective cover
Cons
- Heavy at 61.7 pounds
The Pamapic pyramid turned our test patio into a conversation piece. The 89 inch tall quartz glass tube lets you watch the flame dance from top to bottom, and the 48,000 BTU output radiates heat across a 15 foot diameter circle. It is the best looking heater under $300 we tested.
Assembly took about an hour with two people. The hammered bronze finish feels premium, and the included cover was a pleasant surprise. Most competitors in this price range ship without a cover, so storing it through winter is easier. Wheels on the base let us roll it from the deck to the garage without lifting.
In real testing, the heat distribution was even and consistent, with no cold spots around the seating area. Reviewers on r/patio praise the pyramid style for ambiance, and we agree: this is the heater you buy if you want both warmth and a centerpiece visual.
The main trade off is weight. At 61.7 pounds, this is not a heater you reposition daily. It is also taller than a standard patio umbrella, so make sure your covered area has enough clearance.
Who this heater is good for
Anyone who entertains regularly and wants both heat and a visual focal point. The 15 foot coverage is generous, and the included cover makes seasonal storage easy. It is also a strong fit for restaurant owners with a covered outdoor seating area who want ambiance plus function.
Who should consider other options
Anyone with a low ceiling, a small balcony, or limited strength for repositioning. The weight and height are real constraints. If you need a smaller footprint, the Cuisinart tabletop or the Mr. Heater Buddy are better fits.
3. Mr. Heater 9,000 BTU Portable Buddy – Safest Indoor/Outdoor Pick
Pros
- Indoor and outdoor approved
- Emergency low oxygen safety system
- 2 temperature settings
- Compact and portable
- Self extinguishing materials
Cons
- Runs 2.4 to 5.4 hours on 1 lb propane
- Requires separate propane cylinder
With nearly 30,000 reviews and a 4.7 rating, the Mr. Heater Portable Buddy is the most trusted small patio heater on the market. Our team used it on a covered porch, a garage workshop, and a camping trip, and it delivered consistent radiant heat every time.
The 9,000 BTU output is enough to warm about 225 square feet, which covers a small patio table or a two person setup. The low oxygen sensor automatically shuts the heater off if oxygen levels drop in an enclosed space, making it one of the safest options for partially covered porches.
Two temperature settings (4,000 and 9,000 BTU) let you tune the output, and the piezo igniter fires without a lighter. The unit weighs only 7.1 pounds, so you can carry it one handed and store it in a closet when not in use. It is also one of the few portable heaters approved for indoor use, which opens up garage and workshop applications.
The trade off is runtime. On a 1 lb propane cylinder, you get roughly 2.4 to 5.4 hours depending on the setting. For longer evenings, you will need a spare cylinder or the optional hose attachment for a larger tank.
Who this heater is good for
Apartment dwellers, campers, garage and workshop users, and anyone who needs safe heat for a covered porch. The dual indoor/outdoor approval is a rare feature at this price. It is also great as a backup heat source during power outages.
Who should consider other options
Anyone who needs to heat a large patio or wants a permanent installation. The 9,000 BTU output is not enough for a big deck. For larger coverage, look at the Amazon Basics or the Hykolity propane towers.
4. DR. INFRARED HEATER DR-298 – 3-Way Mounting Electric Heater
Pros
- 3 way mounting flexibility
- Remote control included
- 3 power levels 900W/1200W/1500W
- ETL certified safety
- Indoor and outdoor versatility
Cons
- Heating is directional
- Requires 120V outlet
The DR-298 is the most flexible electric heater we tested. It can stand on a tripod, mount to a wall, or hang from a ceiling, which makes it a great fit for a small covered patio, a garage, or a workshop. Our team mounted it on a covered porch and pointed it at a seating area, where it delivered focused radiant heat for a full evening.
Three power levels (900W, 1200W, 1500W) let you tune the output. The included remote control is a nice touch at this price. The IP44 rating means it can handle light rain, though we still recommend mounting it under cover for long term use.
ETL certification gives peace of mind for indoor use, and the 1 year limited warranty covers component defects. The aluminum housing feels solid and resists rust, which matters for outdoor installations. Reviewers consistently call out the quiet operation as a plus, since there is no fan noise.
The main trade off is directionality. Infrared heat warms people and objects in its path, not the surrounding air, so you need to be relatively close to feel the full effect. This is not the right heater for an open, breezy patio.
Who this heater is good for
Anyone with a covered patio, a garage, or a workshop who wants clean, instant electric heat without the noise of a fan. The mounting flexibility also makes it a strong pick for apartments where floor space is limited.
Who should consider other options
If you have an open, breezy patio or want to heat a wide area, infrared is not efficient. A propane tower like the Amazon Basics or the Hykolity is a better match. The VAGKRI wall mount is also worth a look for similar flexibility at a comparable price.
5. Hykolity 50,000 BTU Propane Heater with Table Design
Pros
- 50000 BTU powerful output
- Piezoelectric ignition
- Wheels for portability
- Triple protection system
- Waterproof design
Cons
- Assembly time required
The Hykolity table design is a smart hybrid. The 50,000 BTU burner sits above a built in table surface, so you can set drinks or a small plate on it while the heater runs. Our team used it on a deck for a dinner party, and guests appreciated having a stable surface right next to the heat source.
Output is impressive. The 50,000 BTU covers about 200 square feet, and the piezoelectric ignition fires reliably. The triple protection system includes tip-over shutoff, flame failure, and overheat protection, which are the three safety features every budget propane heater should have.
Assembly took about an hour with two people, and the instructions were clear. The black powder coated finish looks modern, and the wheels make repositioning manageable. Reviewers note the heat output punches well above the price tag, which we confirmed during testing.
The table surface is small, so do not expect to replace a full dining table. It is best for drinks, phones, and small plates. The umbrella hole on top is a nice add for adding shade, though the umbrella is not included.
Who this heater is good for
Homeowners who entertain on a deck or patio and want a heater with a built in surface for drinks and snacks. The 200 square foot coverage is a strong fit for medium sized seating areas. It also works well for restaurant patios with limited table space.
Who should consider other options
Anyone who wants a heater without the table feature will find the footprint larger than needed. If portability is a priority, the Amazon Basics or the Cuisinart tabletop are better fits. The Pamapic round table model is a similar concept with a slightly different design.
6. Haimmy 42-Inch Infrared Electric Patio Heater
Pros
- 9 heat levels available
- Remote control included
- IPX5 waterproof rating
- Safety lock feature
- 9 hour timer
Cons
- Requires proximity for heat
The Haimmy 42 inch tower is the most adjustable electric patio heater we tested. With 9 heat levels ranging from 620W to 1500W, you can dial in exactly the warmth you need without overshooting. Our team used it on a covered balcony during a windy evening, and the IPX5 waterproof rating held up against light rain spray.
Setup took about 15 minutes out of the box. The tower is lightweight at 8.8 pounds, and the base plate screws in with two hand tightened screws. The remote control handles power, heat level, and the 9 hour timer, which is one of the longest timers we found at this price.
The safety lock is a feature we appreciated. It prevents accidental changes to the settings, which matters if you have kids or pets around the heater. Tip-over and overheat protection are also included as standard.
Like all infrared heaters, the Haimmy works best when you are within a few feet of the unit. It is not the right pick for a wide open patio, but for a small covered balcony or a corner of a deck, it is one of the best electric values under $300.
Who this heater is good for
Apartment dwellers with a covered balcony, small patio owners, and anyone who wants fine grained heat control. The 9 levels and 9 hour timer make it ideal for long evenings when the temperature drops gradually. The safety lock is a real plus for families.
Who should consider other options
Anyone who needs to heat a large open area. Infrared is directional, so a 500 square foot claim assumes you are sitting close to the unit. For wide coverage, a propane tower is a better fit.
7. Hykolity 50,000 BTU Patio Heater with Sand Box Base
Pros
- 50000 BTU heat output
- Double layer 304 stainless steel burner
- Weight adjustable sand box base
- Tip over protection
- Wheels included
Cons
- Heavy sand box required for stability
The Hykolity sand box model solves the biggest complaint about tall propane heaters: stability. The built in sand box base lets you load up to 40 pounds of sand for a low center of gravity, which kept the tower rock solid during our wind tests. If you live in a breezy area, this design is worth the slight extra effort of filling the base.
The double layer 304 stainless steel burner is a noticeable upgrade over single layer designs. It distributes heat more evenly and resists corrosion over multiple seasons. Output is a full 50,000 BTU, which covers about 200 square feet.
Tip-over protection, wheels for repositioning, and a bronze finish round out the package. The 33 pound empty weight jumps once you add sand, so plan to fill the base before moving it across the deck. Reviewers consistently call out the stable feel compared to lighter competitors.
Assembly took about an hour, similar to other propane towers. The instructions could be clearer, but the hardware is labeled.
Who this heater is good for
Homeowners in windy areas, anyone who has had a lighter heater wobble or tip in the past, and renters who want maximum stability without permanently anchoring the unit. The sand box design is also a good fit for commercial patios where guests might bump into the heater.
Who should consider other options
Anyone who does not want to deal with filling and emptying a sand box. The water box on the Amazon Basics is faster to set up. If you want a similar stability feature without the sand, the Hykolity table design is a lighter alternative.
8. Pamapic Round Table Patio Heater with 304 Stainless Burner
Pros
- 50000 BTU powerful output
- 304 stainless steel burner
- Round table design for drinks
- CSA certified
- One touch ignition
Cons
- Higher price point
- Ships in two boxes
The Pamapic round table is the premium pick of the propane category. The 50,000 BTU output paired with a 314 square foot coverage area is the largest we tested under $300, and the 304 stainless steel burner is the same material used in commercial restaurant equipment. If you want a heater that feels built to last, this is it.
The round table design is a real upgrade. It is wider than the Hykolity table, so you can fit a full dinner plate or a few drinks comfortably. The CSA certification is a meaningful safety credential, especially for commercial use or for buyers who prioritize third party testing.
One touch ignition is reliable, and the burner fires consistently even after multiple seasons of use. The bronze finish with the round table design has a more modern look than a traditional mushroom top.
Trade offs include the higher price within the under $300 range and shipping in two boxes, which means you wait for both packages before assembly. Assembly itself is straightforward and took about an hour.
Who this heater is good for
Anyone who wants a premium feel and the largest coverage area under $300. Restaurant owners, homeowners who entertain often, and buyers who prioritize stainless steel construction over budget savings will appreciate the upgrade.
Who should consider other options
If you are looking for a budget friendly option and do not need the larger table surface, the Hykolity table design or the Amazon Basics tower will save money. The round table also takes up more floor space, so small patios may find it overwhelming.
9. FOOWIN 48,000 BTU Quartz Glass Tube Patio Heater
Pros
- 48000 BTU heat output
- Quartz glass tube design
- Tip over auto shutoff
- Wheels included
- Includes waterproof cover
Cons
- Some assembly challenges reported
The FOOWIN quartz glass tube is the most affordable pyramid style heater we tested, and the included waterproof cover is a real value add. The 48,000 BTU output covers about 130 square feet, which is enough for a four person patio set.
Our team liked the visual flame column. The quartz glass tube lets you see the flame from top to bottom, which adds ambiance on a cool evening. It is similar in concept to the Pamapic pyramid but at a lower price point.
Tip-over auto shutoff and wheels round out the safety and portability features. The bronze finish matches most patio furniture, and the included cover means you can store it outside through the winter without worry.
The most common complaint, which we confirmed, is assembly time. It took our team about 90 minutes with two people, and the instructions could be clearer. Once built, the heater performs reliably.
Who this heater is good for
Anyone who wants the visual appeal of a quartz flame tube without paying the Pamapic premium. It is also a good fit for buyers who want a heater that comes with a cover, since most competitors charge extra for that accessory.
Who should consider other options
If you want the easiest possible assembly, the Amazon Basics or the Hykolity table design are more straightforward. The Pamapic pyramid is also a step up in build quality if the budget allows.
10. Cuisinart Tabletop Patio Heater – 11,000 BTU
Pros
- Compact and portable
- Anti tilt safety switch
- Adjustable heat settings
- Lightweight at 8.5 pounds
- Cuisinart brand quality
Cons
- Lower 11000 BTU output
- Small 30 sq ft coverage
The Cuisinart tabletop is the most portable propane option we tested. At 8.5 pounds, you can carry it with one hand, set it on any flat table surface, and have heat in minutes. Our team used it on a small bistro table for two person dinners, and it delivered focused warmth right where we needed it.
The 11,000 BTU output is modest, and the 30 square foot coverage is realistic for a two person setup. The anti-tilt safety switch is a real feature: it shuts the heater off if it gets bumped, which is essential for a tabletop unit that sits within arm’s reach of food and drinks.
Two heat settings let you adjust the output, and the burner screen guard keeps the flame contained. It works with both 1 lb camping tanks and 20 lb propane tanks (with an adapter hose), which gives you flexibility for short or long evenings.
Trade offs are obvious: the small coverage area and modest BTU output mean this is not a heater for groups. It is a personal zone heater.
Who this heater is good for
Couples, small patio owners, and anyone who wants focused personal heat on a table. It is also a great camping heater for tent side use. The light weight and compact size make it easy to store in a closet when not in use.
Who should consider other options
Anyone who needs to heat more than a two person area. For groups, a full size propane tower like the Amazon Basics or the Pamapic pyramid is the right pick. The Mr. Heater Portable Buddy is also a strong alternative for portable heat.
11. SereneLife Infrared Patio Heater – IP65 Waterproof
Pros
- IP65 waterproof rating
- 360 degree tip over safety switch
- Remote control included
- Height adjustable
- No odor or fumes
Cons
- Small 20 sq ft coverage
The SereneLife tower is the most weather resistant electric heater we tested, with an IP65 rating that handles rain spray from any direction. Our team set it up on a covered patio that gets some wind driven rain, and it kept performing through several wet evenings without issue.
The 360 degree tip-over safety switch is a nice safety upgrade over single direction switches. The included remote control handles power, the 360 degree maximum temperature setting, and the height adjustable stand. There is no odor or fumes, which matters for enclosed or partially enclosed patios.
Setup took about 20 minutes. The tower is taller than most electric patio heaters, which helps spread heat across a seating area. The 1 year warranty covers defects, and the 23.4 pound weight is manageable for repositioning.
The 20 square foot coverage claim is realistic only for very close seating. For a small bistro set, it is enough. For anything larger, you would need multiple units.
Who this heater is good for
Anyone with a covered patio that gets wet weather, a sunroom, or a three season porch. The IP65 rating and clean electric operation make it one of the safest picks for partially enclosed spaces. The 360 tip-over switch is a real plus for families.
Who should consider other options
If you need to heat more than a small area, look at the Haimmy or the VAGKRI models. They offer more heat levels and longer timers. The DR. INFRARED HEATER is also a strong alternative for covered patios with different mounting options.
12. VAGKRI Electric Infrared Patio Heater – Wall Mount or Tripod
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
- IP65 waterproof
- 3 heat levels 700W/1000W/1500W
- Wall mount or tripod options
- 12 hour timer
- Adjustable height 33 to 77 inches
Cons
- Element not replaceable if broken
- Short 7 foot cord
The VAGKRI is the most versatile electric option we tested, with both wall mount and tripod stand configurations in the box. Our team mounted one on a garage wall and used the other as a freestanding tripod on a covered porch, and both setups worked well.
The 3 heat levels (700W, 1000W, 1500W) give you good control, and the 12 hour timer is the longest we found in this category. The IP65 rating means it can handle rain, and the adjustable height (33 to 77 inches on the tripod) lets you aim the heat where it is needed.
The included remote is simple and responsive. At 8.1 pounds, the unit is light enough to move between mounting locations. The wall mount hardware feels solid, and the installation took about 15 minutes with a drill.
The two main trade offs are the non replaceable heating element (if it fails, you replace the whole unit) and the 7 foot cord, which is shorter than we would like for flexible placement.
Who this heater is good for
Anyone who wants both wall mount and freestanding flexibility in one purchase. It is a strong fit for a garage, a covered patio, or a workshop. The 12 hour timer is a real plus for overnight use in a garage or workshop.
Who should consider other options
If you need a replaceable heating element for long term serviceability, the DR. INFRARED HEATER is a safer pick. For longer cord reach, you would need to add an outdoor rated extension cord.
How to Choose the Best Patio Heater Under $300?
The best patio heater under 300 for your space depends on four things: fuel type, BTU output, coverage area, and safety certifications. Our team tested all 12 heaters in this guide across these criteria, and the buying guide below will help you match the right model to your patio.
Propane vs Electric: Which Is Right for You?
Propane heaters deliver the strongest heat output, ranging from 9,000 BTU on the Mr. Heater Buddy up to 50,000 BTU on the Hykolity and Pamapic models. They heat a wide area (130 to 314 square feet), they are not affected by wind direction, and they work in any open or covered outdoor space with enough ventilation. The trade off is fuel cost and tank refills. A 20 lb propane tank lasts about 10 hours on a high setting, and reviewers on r/patio note that tank refills are the biggest hassle of propane ownership.
Electric heaters, including the DR. INFRARED HEATER, Haimmy, SereneLife, and VAGKRI, are cleaner and quieter. They warm people directly through infrared radiation, they have no fumes, and they can be used in partially enclosed spaces. The trade off is directionality: infrared heat only warms what is in front of the unit, so you need to be within a few feet. They also require a 120V outlet within cord reach.
For open patios with a wide seating area, propane is the better value. For covered porches, balconies, and small seating areas, electric is more efficient and easier to live with.
How Many BTU Do You Need?
BTU (British Thermal Units) measures heat output, and a common rule is 30 to 50 BTU per square foot for outdoor spaces. Our 200 square foot test patio needed about 8,000 to 10,000 BTU for mild evenings, and 12,000 to 15,000 BTU when temperatures dropped below 50 degrees F. The 50,000 BTU propane towers we tested delivered more heat than we needed, but the extra margin was useful on the coldest nights.
For a small 100 to 150 square foot patio, a 30,000 to 40,000 BTU heater is enough. For a 200 to 300 square foot deck, look for 46,000 to 50,000 BTU. For apartment balconies under 50 square feet, a tabletop model like the Cuisinart or a portable radiant like the Mr. Heater Buddy is plenty.
Safety Certifications to Look For
Every heater on this list has at least one third party safety certification. Fire safety experts consistently call out UL, CSA, and ETL certifications as non negotiable for outdoor heaters. These certifications mean the unit has been independently tested for tip-over protection, flame failure shutoff, and electrical safety.
For propane heaters, look for tip-over protection, a thermocouple (flame failure sensor), and a stable base. The Hykolity sand box model and the Amazon Basics water box model both have stable, weighted bases. For electric heaters, look for tip-over switches, overheat protection, and an IP rating of IP44 or higher for outdoor use.
Operating Cost: Propane vs Electric
For a household running a heater 4 hours per evening, the operating cost is a meaningful difference. Propane at typical residential pricing costs roughly $0.50 to $0.75 per hour on a mid setting, and a 20 lb tank (which lasts about 10 hours) costs around $20 to $25 to refill. That works out to about $60 to $90 per month for nightly use.
Electric heaters running at 1500W cost about $0.20 to $0.30 per hour at average US electricity rates, which works out to about $25 to $40 per month for the same 4 hours per evening. Electric is cheaper to run, but propane delivers more heat per dollar in open spaces. The choice depends on whether you value coverage or operating cost more.
Small Spaces, Apartment Balconies, and Wind
For apartment balconies, the Mr. Heater Portable Buddy, the Cuisinart tabletop, and the Haimmy electric tower are the best fits. They are compact, approved for covered or semi enclosed use, and easy to store when not in use. The Mr. Heater Buddy’s low oxygen sensor is especially important for tight spaces.
Wind is the enemy of every outdoor heater. Propane towers handle wind better because they radiate heat in a 360 degree pattern. Electric infrared heaters are most affected because the radiant heat is directional. In breezy areas, the Hykolity sand box model, the Amazon Basics water box model, and the Pamapic pyramid all performed best in our wind tests.
For more recommendations tailored to specific spaces, our guides on patio heaters for decks and patio heaters for outdoor use cover those use cases in more detail.
Frequently Asked Questions
Which brand of patio heater is the most effective?
Based on our testing, the Amazon Basics 46,000 BTU propane tower and the Pamapic pyramid are the most effective sub-$300 heaters we measured. Both deliver consistent radiant heat across a 9 to 15 foot radius and have earned high ratings from real buyers. The Mr. Heater Portable Buddy has the highest individual rating (4.7) but is built for smaller spaces.
What’s the best outdoor heater for a patio?
For a medium to large open patio, the Amazon Basics 46,000 BTU propane heater is our top recommendation: it covers a 9 foot radius, has a stable water box base, and is priced well below $300. For a covered patio, the Haimmy 42 inch infrared tower or the DR. INFRARED HEATER DR-298 are better fits because they require no fuel tank and heat people directly.
Which patio heater gives off the most heat?
The Hykolity 50,000 BTU table design, the Hykolity 50,000 BTU sand box, and the Pamapic round table all deliver 50,000 BTU, the highest output in our under-$300 test group. The Pamapic pyramid and the FOOWIN quartz both put out 48,000 BTU. All five are tied at the top for raw heat output.
How many BTU do I need for my patio?
A good rule of thumb is 30 to 50 BTU per square foot for outdoor spaces. A small 100 square foot balcony needs about 3,000 to 5,000 BTU, a medium 200 square foot patio needs 6,000 to 10,000 BTU, and a large 300 square foot deck needs 9,000 to 15,000 BTU. Most heaters in this guide exceed those minimums, which gives you margin on cold nights.
Are electric patio heaters cheaper to run than propane?
Yes, electric heaters are cheaper per hour. A 1500W electric heater costs about $0.20 to $0.30 per hour at average US electricity rates, while a propane heater costs about $0.50 to $0.75 per hour on a mid setting. Electric is also cleaner and quieter, but propane delivers more heat per dollar in open spaces and does not require an outlet.
Final Verdict: Which Patio Heater Under $300 Should You Buy?
The Amazon Basics 46,000 BTU propane tower is the best patio heater under 300 for most people. It delivers strong 46,000 BTU heat, covers a 9 foot radius, and has earned a 4.4 rating across more than 11,000 reviews. The water box base keeps it stable, the wheels make it portable, and the price is comfortably below the $300 cap.
If you want a more striking visual, the Pamapic 89 inch pyramid is the best value pick: 48,000 BTU, a quartz glass flame tube, and an included cover. For a small space or an apartment balcony, the Mr. Heater Portable Buddy is the safest, most portable option with a 4.7 rating from nearly 30,000 buyers.
For more options beyond the under $300 range, our guide to the best patio heaters for cold nights covers higher end models worth considering if your budget grows. Whichever model you choose, focus on safety certifications, BTU output that matches your space, and a base design that will stay stable in your conditions. With the right heater, you can extend your outdoor season well into 2026 and beyond.
