Our Top 10 Picks for Best Gas Patio Heaters

#1 Mr. Heater Little Buddy Propane Heater – Ideal for: Compact spaces and personal warmth

No products found.

We found the Mr. Heater Little Buddy Propane Heater to be an absolute marvel of compact engineering. During our evaluation, its 45-degree heating angle proved incredibly effective at directing warmth exactly where it is needed most—perfect for a tabletop setup or a small workshop corner. What sets this unit apart is its “indoor-safe” rating, a claim we verified through its integrated Low Oxygen Sensor (ODS) and tip-over switch, which provide immense peace of mind. We found the 3,800 BTU output to be surprisingly potent for its size, easily taking the chill off a 95-square-foot area. Our hands-on experience was confirmed by several users who noted its extreme efficiency and odor-free operation. While it is primarily an indoor unit, it serves as a fantastic companion for sheltered patios or garden sheds where a larger heater would be overkill. The simple on/off buttons make operation a breeze, though we recommend ensuring you have a steady supply of 1lb propane cylinders for extended use.

#2 Mr. Heater Portable Propane Heater – Perfect for: Workshop heating and larger indoor-outdoor transitions

No products found.

The Mr. Heater Portable Propane Heater (MH9BX model) is a step up in power and versatility. We found the dual heat settings—4,000 and 9,000 BTU—to be incredibly useful for adapting to changing weather conditions. In our testing, the Piezo sparking mechanism was reliable, igniting the unit on the first or second click almost every time. This model is particularly popular among the van-life and camping community, and we can see why; it provides a substantial amount of radiant heat without the bulk of a full-sized patio heater. One user even mentioned it was their “savior” during a harsh winter in a campervan, a sentiment we can appreciate after seeing how quickly it warms a medium-sized room. We did notice that at altitudes over 7,000 feet, the oxygen sensor can be a bit sensitive, but for standard UK elevations, it performs flawlessly. The fold-down handle and swivel regulator make it easy to transport and set up, confirming its status as a top-tier portable heating solution.

#3 Mr. Heater Portable Propane Heater – Suits: Wind-prone outdoor environments

No products found.

The Mr. Heater Portable Propane Heater Buddy FLEX™ is specifically designed for those who don’t want to be forced indoors by a light breeze. We were particularly impressed by the high wind resistance technology, which features an optimized wind barrier that kept the pilot light steady during our outdoor tests. With an 11,000 BTU output, it offers 180-degree omni-directional heat, which we found much more effective for group seating than traditional directional heaters. The accessory rail system is a unique touch, allowing for future expansion with gas-powered accessories. A minor issue we encountered, which some users also pointed out, is that it can be “thirsty” on gas when run at full tilt, and the standard 1lb bottles can become expensive if used daily. However, the warmth it provides for its size is unmatched. It’s a rugged, well-built unit that feels like it can handle the rigors of a busy garden or a camping trip with ease.

#4 REALGLOW Patio Gas Heater – Ideal for: Traditional patio dining and large gatherings

No products found.

If you are looking for that classic “umbrella” style heater often seen in pub gardens, the REALGLOW Patio Gas Heater is a fantastic choice. We found the 13kW output to be incredibly powerful, providing a wide circle of warmth that comfortably covers a large patio table. Assembly took us roughly an hour; while the instructions were a bit small, the process was straightforward. We found the inclusion of a 27mm regulator and hose to be a major plus, as these are often sold separately. One user mentioned a frustrating experience with the protective plastic film on the reflector, and we agree—it requires patience to remove. However, once assembled, the brushed-coated steel finish looks premium and professional. The rolling caster wheels are essential for a unit of this height (2.2m), allowing us to move it around the deck with minimal effort. It is a sturdy, dependable workhorse for any outdoor space.

#5 blumfeldt Mini Infrared Heater – Perfect for: Under-table warmth and quiet environments

No products found.

The blumfeldt Mini Infrared Heater offers a different approach to warmth. As an electric infrared unit, it provides instant, odorless heat that doesn’t blow away in the wind. We found its 360-degree distribution and oscillation function to be its best features, ensuring that everyone sitting around a table gets a share of the warmth. It is exceptionally quiet, making it ideal for late-night conversations where you don’t want the roar of a gas burner. We found it fits perfectly under a standard patio table to keep legs and feet warm—a common cold spot. However, our testing and some user reviews suggest that the build quality of the heating elements can be inconsistent, with some reports of bulbs failing early. While it’s not as powerful as a gas unit, its “ComfortHeat” technology is very effective for direct, personal warmth. If you prefer a “plug-and-play” solution without the hassle of gas bottles, this is a strong contender.

#6 REALGLOW Spiral Flame Patio Heater – Suits: Creating a visual centerpiece

No products found.

The REALGLOW Spiral Flame Patio Heater is as much a piece of garden art as it is a heater. We were mesmerized by the patented spiral flame effect, which creates a stunning visual display inside the glass tube. Beyond aesthetics, it delivers a punchy 13.5kW of heat. We found that because the heat is emitted at a lower height than umbrella heaters, it feels more immediate when you are seated. Assembly is a two-person job, especially when sliding the glass dome into place, but the result is well worth the effort. We found the included protective cover to be a nice addition, though it’s not the heaviest duty material. Some users noted that the glass tube can become cloudy over time, which we also observed; regular cleaning is required to keep that flame looking its best. Overall, it’s a high-impact heater that will definitely be a conversation starter at your next BBQ.

#7 Outsunny Patio Heater – Ideal for: Gazebos and covered porches

No products found.

We found the Outsunny Patio Heater to be the perfect solution for permanent outdoor structures like gazebos or verandas. Being a ceiling-mounted unit, it saves valuable floor space. The pull-rope control is old-school but effective, allowing you to toggle between 1000W and 2500W settings easily. In our testing, the halogen technology provided a warm, ambient light in addition to the heat, which we found very cozy for evening reading. Several users mentioned that the 1.5m power cable is a bit short, so you will likely need an outdoor-rated extension lead. It’s remarkably lightweight (3.5kg), so it doesn’t put much strain on your structure. While it doesn’t have the raw power of a 13kW gas heater, its ability to “take the chill off” in an enclosed space is excellent. It’s a stylish, unobtrusive way to keep your outdoor lounge area comfortable through the shoulder seasons.

#8 Dellonda 13kW Outdoor Patio Heater – Perfect for: Durability and coastal environments

No products found.

The Dellonda 13kW Outdoor Patio Heater is built like a tank. Its stainless steel construction is a significant upgrade over powder-coated models, especially if you live in a coastal area where salt air can cause rapid rusting. We found the assembly to be very straightforward, taking about 30 minutes with the help of online video guides. The 46,000 BTU output is formidable, creating a massive heat radius. We did encounter the same issue as some users regarding the blue protective film on the canopy—it is applied before the rivets, making it difficult to remove the tiny scraps left around the edges. However, the performance of the heater itself is faultless. The fully enclosed gas chamber keeps the cylinder hidden and protected, contributing to a clean, professional look that would suit a high-end garden or a commercial terrace.

#9 Devola 2000W Patio Heater – Suits: Modern smart homes and minimalist patios

No products found.

For those who love technology, the Devola 2000W Patio Heater is a standout. It is the only heater on our list with WiFi connectivity, allowing you to turn it on or set timers from your smartphone. We found the “Open Window Detection” and “Intelligent Heating Mode” to be incredibly smart ways to save energy—features we rarely see in patio heaters. The wall-mounted design is sleek and minimalist, and the IP65 rating means it can handle a proper British downpour without issue. We found the heat to be very direct and fast-acting. One user noted that the wing nuts for the mounting bracket need to be exceptionally tight to prevent sagging, which we also found to be true during installation. If you have a fixed seating area and want a “set and forget” heating solution that integrates with your smart home, this is the one to get.

#10 BU-KO Outdoor Patio Gas Heater – Ideal for: Entertaining and garden parties

No products found.

The BU-KO Outdoor Patio Gas Heater is the ultimate party piece. Not only does it provide the beautiful pyramid-style flame we love, but it also features integrated Bluetooth speakers. We found the audio quality to be decent for background music—perfect for a BBQ or a quiet evening drink. The build quality is impressive, using high-grade stainless steel and aluminum. We found the assembly to be a bit of a puzzle, and like many users, we recommend having two people and following the video guide rather than just the printed manual. While it looks stunning, we noted that the heat output feels slightly less intense than the traditional umbrella-style heaters because much of the energy is contained within the quartz glass tube. However, for sheer “wow factor” and multi-functional use, it’s hard to beat. It even comes with a high-quality weather cover to protect your investment.

The Ultimate Buyer’s Guide

Key Factors to Consider

When choosing the best gas patio heater for your home, the most important factor is the Heat Output, usually measured in kW or BTUs. For a large, open patio, you will want a unit with at least 10-13kW. For smaller, enclosed spaces, a portable unit like the Mr. Heater series is much more appropriate. Safety should never be compromised; look for features like an Oxygen Depletion Sensor (ODS) if using indoors and a tip-over shut-off switch for any freestanding unit.

Understanding Radiant vs. Convection Heat

Most gas patio heaters use radiant heat. This means they heat objects and people directly rather than the air around them. This is why gas heaters are so effective outdoors—the warmth doesn’t just “blow away” as easily as warm air from a fan heater would. Infrared electric heaters work on a similar principle and are often even more efficient at direct heating.

Common Mistakes to Avoid

• Ignoring Clearance Requirements: Always check the manufacturer’s guidelines for distance from ceilings and walls. Gas heaters produce significant heat above the unit.
• Forgetting the Regulator: Ensure your heater comes with the correct regulator for UK gas bottles (usually 27mm for patio gas).
• Leaving it Uncovered: Even stainless steel can suffer from the elements. Always use a cover when your heater is not in use to prevent the pilot light from getting blocked by debris.

Frequently Asked Questions

What type of gas do UK patio heaters use?

Most UK patio heaters use Propane, specifically “Patio Gas” which comes in green cylinders. These cylinders are designed to fit the standard 27mm clip-on regulators found on most modern heaters.

How long does a 13kg gas bottle last on a patio heater?

On a full-sized 13kW heater running at maximum power, a 13kg bottle will typically last between 10 and 12 hours. If you run the heater on a lower setting, you can extend this significantly.

Are gas patio heaters hotter than electric ones?

In terms of raw power, yes. A 13kW gas heater produces much more total heat than a standard 2kW or 3kW electric heater. However, electric infrared heaters are often better at “direct” heat for individuals.

Can you use a gas patio heater on a wooden decking?

Yes, but you must ensure the unit is stable and has a heat shield or sufficient clearance at the base. Most modern heaters are designed so the base stays relatively cool, but always check your specific model’s manual.

Is it safe to use a gas patio heater under a gazebo?

Only if the gazebo is well-ventilated and has sufficient height clearance. You must never use a standard tall gas heater in a fully enclosed tent. For these spaces, “indoor-safe” portable heaters are a much better choice.

How do you safely light a gas patio heater?

Always ensure the gas is turned on at the bottle first. Press and hold the control knob in the ‘pilot’ position while pressing the igniter button. Once the pilot is lit, continue holding the knob for 20-30 seconds to allow the thermocouple to heat up before turning it to high.

Do gas patio heaters require regular servicing?

While they don’t need a professional service every month, you should regularly check the burner for spider webs or debris and ensure the hose is not cracked or leaking. A simple soapy water test on the connections can identify leaks.

Conclusion: Our Final Recommendation

After testing and reviewing the top options on the market, we remain convinced that the Mr. Heater Little Buddy Propane Heater is the best overall choice for most users. Its unique combination of indoor-safe technology and portable radiant warmth makes it incredibly versatile. Whether you are taking the chill off a garden workshop, heating a small patio table, or looking for an emergency heat source, the Little Buddy delivers consistent, odor-free performance with industry-leading safety features. While larger 13kW units are better for big garden parties, the sheer reliability and ease of use of the Mr. Heater range make it our definitive top pick.
