Our Top 10 Picks for Best Patio Heaters

#1 Mr. Heater Big Buddy PRO 18,000 BTU Heater – Best for: Overall Versatility and Portability

In our tests, the Mr. Heater Big Buddy PRO 18,000 BTU Heater quickly established itself as the go-to solution for nearly any heating need. Its performance is simply outstanding for its size. We used it to take the bite out of a cold morning in a two-car garage, and within an hour, the space was comfortable enough to work in a t-shirt. The radiant heat is direct and effective, warming objects and people rather than just the air. The three heat settings (4,000, 9,000, and 18,000 BTU) provide excellent control, allowing us to dial it down for smaller spaces or crank it up for larger, draftier areas. We found the Piezo ignition to be reliable, though it does require a specific sequence to light correctly, a minor learning curve echoed by some users. Once you have the process down, it’s a breeze. Fuel flexibility is a huge plus; the dual regulators for two 1 lb. propane cylinders make it incredibly portable for camping or tailgating, while the option to connect a 20 lb. tank (with a separate hose) makes it an economical choice for extended use on the patio or in a workshop. The built-in safety features, including the tip-over switch and low-oxygen sensor, worked flawlessly in our tests, providing essential peace of mind.

#2 Mr. Heater Portable LP Gas Heater 4000-18000 BTU – Best for: No-Frills Power and Reliability

The Mr. Heater Portable LP Gas Heater 4000-18000 BTU is a close sibling to our top pick, offering the same robust heating capabilities in a slightly different form factor. We found its performance to be identical in terms of heat output, quickly and efficiently warming our test spaces. It’s a true workhorse. In a poorly insulated 12×12 shed, we were able to create a comfortable work environment on a chilly day, an experience confirmed by many users who rely on it for garages, workshops, and even emergency home heating. Assembly is nonexistent; it’s ready to go right out of the box. We appreciate its straightforward, rugged design focused purely on delivering heat. Like its counterpart, it features three heat settings and can be powered by either small canisters or a larger tank, offering great flexibility. The safety shutoffs for tip-over and low oxygen are non-negotiable features for us, and they provide the same level of security here. While some users noted that newer models may not include a fan, we found that the radiant heat is so effective that a fan isn’t strictly necessary, although adding a small external one can help circulate warmth in larger spaces.

#3 Amazon Basics 46,000 BTU Outdoor Propane Patio Heater with Wheels – Best for: Classic Patio and Outdoor Entertaining

For classic, top-down radiant heat for a patio or deck, the Amazon Basics 46,000 BTU Outdoor Propane Patio Heater with Wheels is a fantastic value. This is the style of heater you see at restaurants, and for good reason—it’s incredibly effective at creating a wide circle of warmth. We set this up on a cool evening and found it comfortably heated our entire outdoor seating area, with guests sitting up to 8 feet away feeling the warmth. The 46,000 BTU output is powerful and makes a significant difference. The one-touch ignition fired up consistently for us. Assembly took about an hour, and we’d recommend following the step-by-step graphics in the back of the manual, a tip confirmed by several users to be the clearest path. Peeling the protective film off the reflector panels was the most time-consuming part. We appreciated the stability features, particularly the water box in the base, which we filled with sand for extra heft against the wind. The built-in wheels make it surprisingly easy to move this tall unit around the patio for repositioning or storage. While replacing the tank requires lifting the main housing, it’s a minor inconvenience for the powerful, widespread heat it provides.

#4 EAST OAK 55,000 BTU Patio Heater Table Design – Best for: High-Output and Commercial-Grade Stability

When you need serious heating power combined with thoughtful design, the EAST OAK 55,000 BTU Patio Heater Table Design steps up. The 55,000 BTU output is no joke; we felt a noticeable difference in both heat intensity and coverage area compared to standard 46,000 BTU models. It effectively warmed a 20-foot diameter, making it ideal for larger patios or commercial spaces. We were particularly impressed with the build quality and stability. The sand box in the base is a brilliant feature, adding up to 27 lbs of ballast that kept the unit firmly planted, even in breezy conditions. Assembly was straightforward, taking us under 30 minutes, a sentiment shared by many users who found the instructions clear and the process simple. A unique feature we loved is the integrated drinks stand on the tank lid—it’s a small touch that proves surprisingly useful for holding a beverage or phone while you’re enjoying the outdoors. The triple protection safety system, including tilt and flame-out shutoffs, provides confidence during operation. This isn’t just a heater; it’s a well-engineered piece of outdoor furniture that performs exceptionally well.

#5 DR. INFRARED HEATER DR-238 Outdoor Heater – Best for: Wall-Mounted Garage and Workshop Heating

The DR. INFRARED HEATER DR-238 Outdoor Heater is our top choice for anyone needing a fixed, electric heating solution for a garage, workshop, or covered patio. Unlike propane heaters that heat the air, this infrared unit heats objects directly, which we found to be incredibly efficient. We mounted it over a workbench in a chilly garage, and the radiant warmth was immediate and focused, making tasks much more comfortable without having to heat the entire space. It’s also completely silent. The three power settings (900W, 1200W, and 1500W) are easily managed with the included remote. Installation was simple using the provided brackets, though we agree with some users that the brackets could feel a bit more robust. One important note: running this on its highest setting (1500W) requires a significant amount of power. We found it best to have it on a dedicated 15-amp circuit, especially if you plan to use more than one, to avoid tripping breakers. Its IP55 rating means it’s built to withstand the elements, making it a durable choice for semi-exposed outdoor areas.

#6 EAST OAK 50,000 BTU Patio Heater with Table – Best for: Stylish Design with High Performance

The EAST OAK 50,000 BTU Patio Heater with Table strikes an excellent balance between powerful performance and elegant design. We found its 50,000 BTU output to be more than sufficient for a standard patio, providing a wide, comfortable bubble of warmth on cool evenings. It feels and looks substantial, a step up from more basic models. Assembly took us about an hour, and we found the instructions to be well-written and easy to follow. The standout feature is the round table design integrated into the tank housing. It’s not just for looks; it’s a practical spot to rest drinks and snacks, enhancing the social aspect of your outdoor space. We also liked the convenient access holes in the base, which allow you to operate the propane tank valve without lifting the entire cover—a thoughtful design choice. The build quality, featuring a double-layer stainless steel burner, feels durable and built to last. For those who want a heater that is both a powerful appliance and an attractive centerpiece for their patio furniture, this is an outstanding option.

#7 Pamapic 48,000 BTU Pyramid Flame Patio Heater with Cover – Best for: Ambiance and Visual Appeal

If you’re looking for a heater that’s as much about atmosphere as it is about warmth, the Pamapic 48,000 BTU Pyramid Flame Patio Heater with Cover is a showstopper. The central quartz glass tube houses a mesmerizing dancing flame that becomes an instant focal point on any patio. We found it created a wonderful ambiance for evening gatherings. In terms of heat, it’s different from traditional “mushroom-top” heaters. The heat radiates outward from the column, so you need to be sitting closer to feel its full effect. It’s perfect for seating arrangements clustered around the heater. We found the assembly to be a bit more involved than other models, taking around an hour and a half, a process some users simplified by following video tutorials. Once built, the unit feels very sturdy and wind-resistant due to its low center of gravity. The pulse ignition worked reliably, and the included cover is a high-quality addition that protects the unit when not in use. While it may not throw heat as far as a conventional tower, its unparalleled visual appeal makes it a top choice for style-conscious homeowners.

#8 GASLAND MHA18BN 18,000 BTU Propane Radiant Heater – Best for: Quiet, Indoor-Safe Emergency Heating

The GASLAND MHA18BN 18,000 BTU Propane Radiant Heater excels as a quiet, efficient, and mobile heating solution. Its cabinet design neatly conceals a 20 lb propane tank, creating a tidy and self-contained unit that’s easy to roll around on its casters. We were most impressed by its completely silent operation. With no fans, it’s perfect for spaces where noise is a concern, like a home office or a quiet workshop. The radiant heat is potent, and the three ceramic heating panels allow for adjustable output up to 18,000 BTU. In our tests, it heated up an office space above a garage remarkably quickly, a finding confirmed by many users who praise its efficiency. The non-electric operation makes it an excellent choice for emergency preparedness during power outages. Setting it up was simple, and the safety features, including the ODS and tip-over shutoff, provide crucial peace of mind for indoor use in ventilated areas. For anyone needing a powerful, silent, and easily movable heater that hides the tank, this is a top contender.

#9 Briza 1500W Infrared Patio Heater – Best for: Portable and Versatile Electric Heating

The Briza 1500W Infrared Patio Heater offers incredible versatility for an electric model. Out of the box, we were impressed with the multiple setup options: it can be mounted to a wall or ceiling, or used portably with the included tripod stand. We opted for the tripod, which was sturdy and easy to adjust. This flexibility makes it a great solution for renters or anyone who doesn’t want a permanent installation. The carbon infrared technology provides instant warmth. We used it on a three-season porch on a 57°F evening and felt comfortably warm sitting 5-6 feet away. This is a common experience among users who find it perfect for taking the chill off smaller, defined spaces. The remote control is a handy feature, allowing you to adjust the three heat levels without getting up. Its IP55 rating gives it solid protection against dust and rain, making it a reliable choice for outdoor use. The tip-over sensor is another key safety feature that worked as advertised, shutting the unit off instantly when we nudged it over. For targeted, portable, electric heat, the Briza is hard to beat.

#10 thermomate PHF18B 18000 BTU Propane Heater – Best for: Budget-Friendly Mobile Heating

The thermomate PHF18B 18000 BTU Propane Heater is a solid, budget-friendly option that shares many of the best qualities of higher-priced cabinet heaters. We found it to be highly effective, delivering substantial radiant heat across its three adjustable settings. It did a great job making our screened-in patio comfortable on a cool morning when temperatures were in the 40s. The design is compact and highly portable, thanks to the five locking casters that make it easy to roll into position and secure. Like the GASLAND model, it operates silently and is great for emergency use since it doesn’t rely on electricity. The ODS and tip-over protection are essential safety features that give confidence when using it in workshops or garages. While we found the ignition dial to be slightly imprecise—the panels lit up at points not perfectly aligned with the markings—it was a minor quirk that didn’t affect performance once we got used to it. For anyone seeking the convenience of a mobile, tank-in-cabinet propane heater without a premium price tag, this thermomate unit delivers excellent value and performance.

The Ultimate Buyer’s Guide: How to Choose The Right Product for You

Key Factors to Consider

• Heat Output (BTUs/Watts): For propane heaters, this is measured in British Thermal Units (BTUs). A small portable unit might be 4,000-18,000 BTU, while a large tower can be 40,000-55,000 BTU. For electric heaters, look at wattage (typically 900W-1500W). More BTUs or watts mean more heating power and a larger coverage area.
• Fuel Type: The most common choices are propane and electric. Propane offers high heat output and great portability but requires refueling. Electric heaters are convenient for areas with an outlet, produce no emissions, and are often safer for semi-enclosed spaces, but they may offer less raw heating power.
• Heating Method: Radiant heaters (like infrared and most propane models) heat objects and people directly. They are great for open, breezy spaces. Convection heaters warm the air, which then circulates. These are less effective in windy outdoor conditions.
• Safety Features: This is non-negotiable. Look for an automatic tip-over shutoff, which cuts power or gas if the unit is knocked over. For propane heaters used in enclosed spaces like garages, an Oxygen Depletion Sensor (ODS) is critical.
• Portability and Size: Consider where you’ll use the heater. Will it stay in one place or do you need to move it? Large towers often have wheels, while smaller units have carry handles. Wall-mounted electric heaters are great for saving floor space.

Understanding BTU and Heating Coverage

A BTU, or British Thermal Unit, is a measure of heat energy. One BTU is the amount of heat needed to raise the temperature of one pound of water by one degree Fahrenheit. In practical terms, a higher BTU rating means a more powerful heater. However, the manufacturer’s claimed “heating coverage” (e.g., 450 sq ft) is often an ideal-case scenario. Real-world effectiveness depends heavily on ambient temperature, wind, and whether the space is open or enclosed. In an open patio on a windy night, even a powerful 46,000 BTU heater will have its effective range reduced. Conversely, an 18,000 BTU heater in a closed, insulated garage will feel incredibly potent.

Common Mistakes to Avoid

• Underpowering Your Space: Buying a small, 1500W electric heater and expecting it to warm a large, open deck will lead to disappointment. Match the heater’s power to your space and expectations.
• Ignoring Safety Clearances: All heaters specify a safe distance required from combustible materials (walls, furniture, ceilings). Ignoring these is a serious fire hazard.
• Using Indoor Heaters Outdoors: Never use a heater outdoors unless it is specifically rated for outdoor use. Outdoor models are built to withstand moisture and have different safety mechanisms.
• Forgetting Ventilation: Propane heaters consume oxygen and produce carbon monoxide. Never use them in a completely unventilated space. Always crack a door or window as recommended by the manufacturer.

Frequently Asked Questions

How much electricity does an electric patio heater use?

An electric patio heater’s consumption depends on its wattage. A common 1500-watt heater running for one hour will use 1.5 kilowatt-hours (kWh) of electricity. You can calculate the cost by multiplying the kWh by your local electricity rate. For example, if your rate is $0.15 per kWh, running a 1500W heater would cost about 22.5 cents per hour.

Are electric patio heaters safe to use in the rain?

Only if they have an appropriate IP (Ingress Protection) rating. Look for a rating of at least IPX4, which protects against splashing water. A higher rating like IP55 (as seen on the Briza and DR. INFRARED HEATER models) offers protection against low-pressure water jets and dust, making them much safer and more durable for exposed outdoor environments.

Do electric patio heaters need to be professionally installed?

Most plug-in electric patio heaters, including portable and tripod models, do not require professional installation. You simply assemble them and plug them into a suitable outlet. However, for hardwired, permanently mounted units, it is highly recommended to hire a licensed electrician to ensure the wiring is safe and up to code.

What is the difference between an infrared and a standard electric heater?

Standard electric heaters typically use a convection method—they heat an element, which in turn heats the surrounding air that then circulates. This is inefficient for outdoor spaces. Infrared heaters use radiant heat, emitting infrared rays that travel through the air and directly warm any objects or people they strike, similar to the sun’s warmth. This is far more effective for outdoor or drafty environments.

Can you use an electric patio heater indoors?

Yes, most electric patio heaters are safe for indoor use, provided you follow all safety clearances from flammable materials. They don’t produce emissions like propane heaters, making them a safe choice for garages, workshops, or even chilly rooms in the house.

How effective are electric patio heaters in cold weather?

Electric patio heaters are most effective at taking the chill off cool evenings, typically when temperatures are above 45-50°F. In very cold, windy weather, a 1500W electric heater will struggle to provide significant warmth unless you are very close to it. For true cold-weather performance, a high-BTU propane heater is generally more effective.

What are the benefits of a wall-mounted vs a freestanding electric heater?

A wall-mounted heater is a permanent solution that saves valuable floor space and eliminates the risk of being tipped over. It’s ideal for targeted heating in a workshop or over an outdoor seating area. A freestanding heater offers portability and flexibility. You can move it exactly where you need the heat, making it perfect for versatile spaces or for those who don’t want a permanent installation.
