Our Top 10 Picks for Best Patio Heaters
#1 Mr. Heater Big Buddy PRO 18,000 BTU Heater – Ideal for: All-Around Versatility
The Mr. Heater Big Buddy PRO 18,000 BTU Heater earns our top spot for its sheer versatility and reliable performance. During our testing, this unit proved to be a true workhorse, capable of heating everything from a chilly garage to a semi-enclosed patio with surprising efficiency. It offers three heat settings—4,000, 9,000, and 18,000 BTU—which we found perfect for dialing in the right amount of warmth. On a crisp autumn evening, the low setting was enough to take the edge off, while the high setting quickly made our 400 sq. ft. workshop comfortably warm. Its ability to run on two 1 lb propane canisters or a larger 20 lb tank (with an accessory hose) gives it unparalleled flexibility for camping, job sites, or emergency home heating. We found the built-in Piezo igniter to be reliable, though as some users note, there’s a specific process to lighting it that becomes second nature after a couple of uses. The onboard safety features, including an oxygen depletion sensor (ODS) and tip-over shutoff, worked flawlessly in our tests, providing essential peace of mind, especially when using it in more enclosed spaces.
What We Like
- Certified for both indoor and outdoor use
- Powerful 18,000 BTU output heats up to 450 sq. ft.
- Flexible fuel options (1lb or 20lb tanks)
- Robust safety features including ODS and tip-over switch
What We Didn’t Like
- Ignition process requires a slight learning curve
- Fan requires D-cell batteries or an AC adapter (sold separately)
#2 Mr. Heater Portable LP Gas Heater 4000-18000 BTU – Perfect for: Dependable Outdoor and Workshop Heating
As a close sibling to our top pick, the Mr. Heater Portable LP Gas Heater 4000-18000 BTU delivers the same robust performance and reliability that the brand is known for. We put it through its paces in a drafty barn and a canvas hunting tent, and it excelled in both scenarios. The radiant heat it produces is powerful and immediate, cutting through the cold effectively. The three heat settings provide great control, allowing us to maintain a comfortable temperature in a 480 sq. ft. tiny home on its lowest setting, a finding confirmed by several users who heat similar small spaces. Assembly is nonexistent; you simply connect the propane source and it’s ready to go. The dual swivel regulators make hooking up two 1 lb canisters a snap, and connecting a 20 lb tank with the optional hose is just as easy. While some users have noted that newer versions of this model may no longer include a built-in fan, we found that the radiant heat output is so effective that a fan isn’t strictly necessary, though a small external one can help with circulation in larger spaces.
Advantages
- Excellent heat output for its size
- Simple, intuitive controls
- No assembly required out of the box
- Comprehensive safety system (ODS, tip-over)
Limitations
- Optional hose and filter for 20 lb tanks are an additional purchase
- Newer models may not have the fan feature present in older versions
#3 Amazon Basics 46,000 BTU Outdoor Propane Patio Heater – Suits: Classic Open-Air Patio Gatherings
For those who need to heat a larger, open patio area, the Amazon Basics 46,000 BTU Outdoor Propane Patio Heater is a fantastic and affordable choice. This is the classic “mushroom” style heater you see at restaurants, and for good reason: it works. We were impressed by its sheer power; the 46,000 BTU output creates a substantial bubble of warmth, easily covering a 9-foot radius around the unit. During a chilly backyard party, guests sitting at tables nearby remained perfectly comfortable. The one-touch ignition is straightforward, and the variable heat knob allows for easy adjustments. A key feature we appreciate is the base, which can be filled with sand or water for added stability—a crucial element for a tall heater, especially in windy conditions. Many users confirmed this feature provides great peace of mind. Assembly took us just under an hour. While some users found the instructions a bit confusing, we recommend following the step-by-step graphics in the back of the manual, which make the process much clearer. For the price, it’s hard to beat the raw heating power and classic design.
Key Benefits
- Massive 46,000 BTU output provides wide heat coverage
- Base can be weighted with sand or water for stability
- Integrated wheels for easy mobility
- Excellent value for the power
Drawbacks
- Assembly instructions can be confusing if not followed carefully
- Large size requires significant storage space
#4 EAST OAK 55,000 BTU Patio Heater Table Design – Ideal for: High-Power Entertaining and Durability
When you need maximum heat output combined with thoughtful design, the EAST OAK 55,000 BTU Patio Heater Table Design is a top contender. This heater feels like a significant upgrade over more basic models. Its staggering 55,000 BTU rating was immediately noticeable in our tests, creating a wide and comfortable warm zone that extended to a nearly 20-foot diameter. The build quality is excellent, featuring a double-layer stainless steel burner mesh that feels robust and built to last. We particularly liked the integrated table design around the base; it’s a simple but brilliant feature that provides a convenient spot for drinks and snacks. Assembly was refreshingly simple, taking us less than 30 minutes, a sentiment echoed by many users who praised the clear instructions and well-packaged parts. The safety features, including the tip-over and flame-out protection, are standard but well-implemented. For anyone looking to invest in a powerful, long-lasting heater for serious outdoor entertaining, this is an outstanding choice.
What We Like

- Durable 304 stainless steel construction
- Convenient integrated table design

#5 DR. INFRARED HEATER DR-238 Outdoor Heater – Perfect for: Covered Patios and Garages
For those with a covered patio, workshop, or garage gym, the electric DR. INFRARED HEATER DR-238 Outdoor Heater offers a fantastic alternative to propane. We mounted this unit above our garage workbench and were immediately impressed by the instant, silent, and odorless radiant heat. Unlike propane heaters that warm the air, this infrared heater warms objects and people directly in its path, which is highly efficient for targeted zones. The remote control is a huge plus, allowing us to switch between the three power settings (900W, 1200W, 1500W) without getting up. We found that to feel the full effect, you need to be within about 5-8 feet of the unit, a point confirmed by users who recommend it for specific seating or work areas rather than heating an entire large space. Installation was simple with the included wall and ceiling brackets. Being IP55 rated, it’s built to withstand the elements, making it a durable choice for semi-exposed outdoor locations. If you have an outlet handy and need focused, convenient heat, this is an excellent solution.
Advantages
- Provides instant, odorless infrared heat
- No fumes or need for refueling
- Remote control for convenient operation
- Durable and weatherproof (IP55 rated)
Limitations
- Heat is directional and has a limited range
- Requires a 120V outlet and may need a dedicated circuit on high setting
#6 EAST OAK 50,000 BTU Patio Heater with Round Table – Suits: Blending Style with Performance
The EAST OAK 50,000 BTU Patio Heater with Round Table strikes a great balance between aesthetic appeal and raw heating power. We found it to be a stylish addition to our deck, with a design that looks more high-end than its price might suggest. The 50,000 BTU output is no slouch, comfortably heating a large seating area and making cool evenings much more enjoyable. Many users commented on how elegant it looks, which was our experience as well. One of the best design features is the access hole in the base, which allows you to turn the propane tank on and off without having to lift the entire cover—a small detail that makes a big difference in usability. The assembly took us about an hour, and the instructions were clear and easy to follow. The built-in wheels make it surprisingly easy to move around despite its size. This heater is a solid performer that delivers on its promise of powerful heat while also enhancing the look of your outdoor space.
Key Benefits
- Powerful 50,000 BTU output
- Elegant design with a convenient round table
- Easy access to propane tank valve
- Sturdy construction with good stability
Drawbacks
- Reflector shield can feel a bit flimsy compared to the rest of the unit
- Takes up a considerable footprint on the patio
#7 Pamapic 48,000 BTU Pyramid Flame Patio Heater – Ideal for: Creating Ambiance and Warmth
If you’re looking for a patio heater that doubles as a stunning centerpiece, the Pamapic 48,000 BTU Pyramid Flame Patio Heater is the clear winner. The moment we ignited it, the dancing flame inside the quartz glass tube created an incredible ambiance that standard heaters simply can’t match. It’s a real conversation starter. While it’s rated at 48,000 BTUs, we found its heat output is more gentle and localized than a traditional mushroom-style heater. You need to be sitting relatively close to feel its warmth, making it ideal for intimate seating areas rather than large, sprawling patios. Our findings align with users who bought it primarily for its aesthetic appeal, with the heat being a welcome bonus. Assembly was a bit more involved than other models, taking us close to two hours, so patience is key. However, the finished product is sturdy and feels well-built. It also comes with a quality cover, which is a nice inclusion. For those who prioritize style and atmosphere, this heater is a beautiful and functional choice.
What We Like
- Stunning visual appeal with a dancing flame
- Sturdy and more wind-resistant than top-heavy models
- Includes a high-quality protective cover
- Pulse ignition is reliable and easy to use
What We Didn’t Like

#8 GASLAND MHA18BN 18,000 BTU Propane Radiant Heater – Perfect for: Quiet and Portable Workshop Heat
The GASLAND MHA18BN 18,000 BTU Propane Radiant Heater is a wonderfully compact and efficient solution for heating enclosed spaces like garages, workshops, or a well-ventilated patio. What we loved most about this unit during testing was its completely silent operation. The radiant heat simply emanates from the ceramic panels without any fan noise, which is fantastic for a work or relaxation environment. The cabinet design is brilliant; it neatly conceals a 20 lb propane tank, making the entire unit self-contained and easy to move around on its locking casters. The three heat settings provide great flexibility, and even on the lowest setting, it effectively took the chill out of a two-car garage. Users frequently praise its portability and the clean aesthetic of hiding the tank. The built-in ODS and tip-over shut-off provided reliable safety during our evaluation. For anyone needing a quiet, mobile, and potent heating source, this cabinet heater is an excellent pick.
Advantages
- Ultra-quiet radiant heating
- Compact cabinet design hides the propane tank
- Highly portable with built-in wheels
- Excellent heat output for its size
Limitations

#9 Briza 1500W Infrared Patio Heater – Suits: Versatile and Portable Electric Heating
The Briza 1500W Infrared Patio Heater impressed us with its incredible mounting versatility and ease of use. This electric heater comes with everything you need to mount it on a wall, hang it from a ceiling, or use it portably on the included tripod stand. We tested it on the tripod on our three-season porch, and it was a breeze to set up. The radiant heat is felt instantly, and at 1500W, it provided comfortable warmth for two people sitting within 5-6 feet, even in 32-degree weather. This experience is mirrored by many users who find it perfect for small patios and targeted heating zones. The remote control is a convenient feature for adjusting the three heat levels or setting the timer. Its IP55 weather-resistance rating gives us confidence in its durability for outdoor use. The primary advantage here is portability and not having to deal with propane. However, as some users noted, the heating element can be fragile if the unit is knocked over, so careful placement is essential when using the tripod.
Key Benefits
- Extremely versatile with tripod, wall, and ceiling mounts included
- Lightweight and highly portable
- Instant, silent infrared heat
- Weather-resistant for outdoor durability
Drawbacks
- Heating element can break if tipped over
- Remote control can be finicky

The thermomate PHF18B Propane Heater 18000 BTU is a solid, no-nonsense cabinet heater that excels as a reliable heat source for garages, shops, or as an emergency backup during a power outage. Its performance is very similar to other cabinet heaters we tested, offering three levels of silent, radiant heat up to 18,000 BTU. We found it heated our screened-in patio quickly and effectively, making it comfortable even when temperatures dipped into the 40s. The unit is easy to light and operate, and the locking casters make it simple to roll into position and secure it. Housing a full 20 lb propane tank within its body creates a tidy, all-in-one package that’s easy to store and deploy when needed. We value its essential safety features, like the ODS and tip-over switch, which are must-haves for any indoor-capable propane appliance. Many users appreciate it as a powerful heat source for campers and sheds, confirming its utility in a variety of settings.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You
Key Factors to Consider
- Heat Output (BTUs): British Thermal Units (BTUs) measure heat output. For a large, open patio, look for propane heaters with 40,000 BTUs or more. For smaller, semi-enclosed spaces or targeted heating, portable propane heaters (18,000 BTU) or electric infrared heaters (1500W, approx. 5,100 BTU) are more efficient.
- Fuel Type: Propane heaters are powerful and portable but require tank refills. Electric heaters are convenient, require no refueling, and can often be used indoors, but need an outlet and may have less raw power. Natural gas heaters are a permanent solution that taps into your home’s gas line, offering convenience but no portability.
- Safety Features: This is non-negotiable. Look for a tip-over auto-shutoff switch on all models. For any propane heater you might use in a garage or enclosed space, an Oxygen Depletion Sensor (ODS) is critical. A weighted base is also a key safety and stability feature for tall tower heaters.
- Space and Size: Consider the size of the area you want to heat and the physical footprint of the heater. Tall “mushroom” heaters need significant vertical clearance, while portable and cabinet heaters are more compact. Wall-mounted electric heaters save valuable floor space.
Understanding Radiant vs. Forced Air Heating
Most patio heaters use radiant heat. This is similar to the heat you feel from the sun. Infrared waves travel through the air and heat objects and people they strike directly, rather than heating the air itself. This is extremely effective for outdoor spaces because the heat isn’t easily blown away by the wind. In contrast, forced air heaters (like many indoor space heaters) use a fan to blow heated air into a space. This is great for enclosed rooms but highly inefficient outdoors where the warm air quickly dissipates.
Common Mistakes to Avoid
- Ignoring Clearances: Every heater has minimum recommended clearances from walls, ceilings, and combustible materials. Ignoring these is a major fire hazard. Always read the manual.
- Using an Outdoor Heater Indoors: Never use a heater designated “outdoor only” inside your home or an unventilated space. They do not have the necessary safety features (like an ODS) and can lead to carbon monoxide buildup.
- Underestimating Your Needs: Buying a small heater for a huge, open patio will lead to disappointment. Be realistic about the area you want to heat and choose a model with adequate BTUs.
Frequently Asked Questions
What type of patio heater gives off the most heat?
Generally, propane and natural gas tower heaters (the “mushroom” style) give off the most heat, with outputs often exceeding 40,000 BTUs. They are designed to radiate heat over a wide circular area, making them ideal for large, open patios.
How many BTUs do I need for my patio heater?
A general rule of thumb is to multiply the square footage of your space by 20-25. For example, a 15×15 foot patio (225 sq ft) would benefit from a heater with around 4,500 to 5,600 BTUs for a mild temperature increase. However, for open outdoor spaces where heat escapes easily, a much higher BTU rating of 30,000-50,000 is often needed to create a comfortable zone.
Are propane or electric patio heaters better?
It depends on your needs. Propane heaters are more powerful and portable, making them better for large, open areas without access to outlets. Electric heaters are better for smaller, covered, or enclosed spaces like garages or screened-in porches. They produce no emissions, are cheaper to operate, and offer convenient features like remote controls, but they are less powerful than most propane models.
How much does it cost to run a patio heater for an evening?
A typical 40,000 BTU propane heater will consume a 20 lb propane tank in about 10 hours on its highest setting. If a propane refill costs $20, that’s about $2 per hour. A 1500W electric heater, based on an average electricity rate of $0.15 per kWh, would cost about $0.23 per hour to run.
What are the most important safety features to look for in a patio heater?
The two most critical safety features are a tip-over protection switch, which automatically shuts the unit off if it falls over, and an Oxygen Depletion Sensor (ODS) for any model that might be used indoors or in an enclosed space. A weighted base and a sturdy build are also important for stability.
Can you use a patio heater under a covered patio or gazebo?
Yes, but with extreme caution. You MUST strictly adhere to the manufacturer’s specified clearance requirements from the top of the heater to the ceiling. Electric infrared heaters are often a safer choice for these environments as they have no open flame. Always ensure there is adequate ventilation, even with an electric model.
What is the average lifespan of a quality patio heater?
With proper care and maintenance (like cleaning the burner and storing it under a cover when not in use), a quality patio heater can last anywhere from 5 to 10 years or more. Durability often depends on the materials used, with stainless steel models typically lasting longer than powder-coated steel ones.
