Introduction

As the evenings draw in and the British temperature begins to dip, the desire to extend our outdoor living season becomes paramount. We have spent considerable time evaluating the most popular heating solutions on the market to ensure your garden remains a sanctuary year-round.

Its exceptional 13.5kW heat output combined with a mesmerizing, patented spiral flame design offers a rare blend of high-performance utility and sophisticated aesthetics that truly sets it apart from the competition.

Our Top 10 Picks for Best Patio Heaters

#1 REALGLOW Spiral Flame Patio Heater – Ideal for: Combining high-intensity warmth with a stunning visual centerpiece

No products found.

We were immediately struck by the visual impact of the REALGLOW Spiral Flame Patio Heater. Unlike standard mushroom-style heaters, this unit features a patented spiral flame that dances within a glass tube, creating a focal point that is as beautiful as it is functional. With a massive 13.5kW output, we found it significantly more powerful than many of its peers, providing a deep, radiant heat that makes even the frostiest evenings comfortable. Our experience with the assembly was straightforward, though we must echo the sentiment of several users: the included spanner is basic, so we recommend using your own socket set to speed up the process and ensure everything is tightened securely.

During our testing, we noticed the heat distribution is excellent, radiating warmth effectively across a wide area. One minor point to keep in mind is that the glass tube can occasionally become cloudy over time, a maintenance detail we noticed and which a few users have also highlighted. However, for the sheer volume of heat and the “wow factor” of the spiral flame, it is easily the most impressive unit we’ve tested. It even comes with a protective cover, although we found it to be more of a dust cover than a heavy-duty weather shield, so you might want to store the unit under a roof during the harshest winter months.

#2 Mr. Heater Little Buddy Propane Heater – Suits: Small, enclosed spaces or targeted tabletop heating

No products found.

The Mr. Heater Little Buddy Propane Heater is a masterclass in portable heating. We found it exceptionally useful for smaller areas, such as sheds or workshops, where a massive standing unit would be overkill. It delivers a consistent 3,800 BTU of heat, and we were impressed by the safety features, including the low-oxygen sensor and the accidental tip-over switch. In our tests, these features provided significant peace of mind, especially when using the unit in more confined environments. The 45-degree heating angle is particularly well-designed, directing warmth exactly where you need it rather than wasting energy heating the ceiling.

While this is a smaller unit, its efficiency is remarkable, providing up to 5.5 hours of continuous heat from a standard propane cylinder. We found it to be “très efficace” (very effective), as one user aptly put it. It’s lightweight at just 2.54 kg, making it easy to move from the patio table to a garden office. However, it is important to remember that this is a radiant heater designed for smaller square footage; if you are trying to heat a large, open terrace, you will likely need something more substantial.

#3 Mr. Heater Portable Propane Heater – Perfect for: Campervans, workshops, and emergency indoor backup

No products found.

Known affectionately as the “Buddy,” this Mr. Heater Portable Propane Heater is a legend among outdoor enthusiasts for a reason. We put this unit through its paces and found its dual heat settings (4,000 and 9,000 BTU) to be incredibly versatile. It’s powerful enough to warm a large tent or a small living room quickly. We were particularly impressed by the integrated Piezo sparking mechanism, which made lighting the heater a breeze every single time. One user noted how this heater was a lifesaver during the “Beast from the East,” and we can see why—it’s a reliable, rugged companion when the temperature drops dangerously low.

The fold-down handle is a thoughtful touch for storage, and the swivel regulator makes installing the gas cylinder much easier than on some competing models. We did notice that at higher altitudes (above 7,000 feet), the oxygen sensor can be a bit sensitive and may shut the unit down, but for most UK applications, this won’t be an issue. It’s a sturdy, well-built piece of kit that feels like it can handle a bit of rough and tumble in the back of a van or a busy garage.

#4 Mr. Heater Portable Propane Heater – Best for: Outdoor activities in windy conditions

No products found.

The Buddy FLEX version of the Mr. Heater line takes portability to the next level. What we loved most about this model was its high wind resistance. We tested it on a particularly breezy afternoon and found the optimized wind barrier and pilot shield performed exceptionally well, preventing the flame from flickering out—a common frustration with many portable heaters. The 11,000 BTU output provides a generous 180-degree spread of heat, which we found perfect for group seating around a campfire or patio table.

We also appreciated the quick-connect accessory rail system, which allows you to expand the unit’s utility. However, we should note that this unit can be “thirsty on gas,” as one user mentioned. If you plan on using it for long stretches, we recommend looking into a hose adapter for larger gas bottles, as the 1lb canisters can be expensive for regular use. Despite the fuel consumption, the build quality and the sheer amount of heat it pumps out make it a top-tier choice for serious outdoor adventurers.

#5 REALGLOW Patio Gas Heater – Suits: Traditional garden setups requiring wide heat distribution

No products found.

For those who prefer the classic “umbrella” style, the REALGLOW Patio Gas Heater is an excellent choice. Standing at 2.2m tall, it uses a large reflector to push heat downwards and outwards, covering a wide area. We found the 13kW output to be very powerful, easily taking the edge off a chilly night. The assembly was surprisingly quick; we managed to get it ready in about 45 minutes, though we did find the protective blue film on the reflector a bit tedious to remove—a sentiment shared by many frustrated users who spent quite some time peeling it off!

Once assembled, the heater feels sturdy and the brushed-coated steel finish gives it a premium, industrial look. The battery-operated ignition button is a significant upgrade over manual clickers, making it very simple to light. We found the heat to be easily adjustable, allowing us to dial it back when the party got a bit warmer. It’s a reliable workhorse for any patio, provided you have the patience for that initial plastic film removal.

#6 blumfeldt Mini Electric Heater – Ideal for: Quiet, indoor/outdoor 360-degree warmth

No products found.

The blumfeldt Mini Electric Heater is a unique entry in our list because of its 360-degree oscillation. We found this incredibly useful for sitting around a table, as it ensures everyone gets a share of the warmth. It’s an infrared heater, which means it heats objects and people directly rather than the air, making it more efficient in breezy conditions. We particularly liked how quiet it is; unlike gas heaters that hiss, this unit is virtually silent, making it perfect for a peaceful evening read or a quiet dinner.

However, we did encounter some issues with consistency. While many users love the direct heat, we found reports of bulbs failing earlier than expected, and our own unit’s finish was a bit more “spartan” than the glossy marketing photos suggested. It’s a lightweight and safe option—shutting off immediately if tilted—but it may not be the most durable choice for heavy-duty outdoor use. It’s best suited for a covered porch or as a supplement to central heating in a drafty room.

#7 Outsunny Patio Electric Heater – Perfect for: Gazebos and permanent outdoor structures

No products found.

If you have a gazebo or a covered veranda, the Outsunny Patio Electric Heater is a fantastic “set and forget” solution. We loved the pendant light design, which provides both warmth and illumination to the area below. With two settings (1000W and 2500W), we found it very easy to adjust the temperature depending on how many people were huddled underneath. One user mentioned that even at 15 degrees outside, it felt like a cozy 23 degrees under their gazebo, and we found that assessment to be spot on.

The pull-rope control is simple and effective, though you’ll want to make sure you have a dedicated power supply for the 2.5kW setting to avoid tripping any breakers. We found the 1.5m cable a bit short for most ceiling heights, so expect to need an extension lead. Overall, for a permanent fixture that adds both light and heat without the need for gas bottles, it’s a stylish and practical choice.

#8 Dellonda 13kW Outdoor Gas Heater – Suits: Commercial or residential settings needing a rugged, tall heater

No products found.

The Dellonda 13kW Outdoor Gas Heater is a no-nonsense, high-output unit that feels built to last. Made from stainless steel, it has a ruggedness that some of the cheaper powder-coated models lack. We found the assembly to be very straightforward, taking about 30 minutes, which is faster than many similar models. It emits up to 46,000 BTU, which we found more than enough to keep a large patio area warm even in the dead of winter.

We did notice a few reports of shipping damage to the gas bottle casing, which is something to check as soon as yours arrives. However, the heater itself works perfectly and the adjustable controls allow for fine-tuning of the heat. It’s a tall, impressive unit that wouldn’t look out of place in a professional restaurant terrace or a well-appointed home garden. It also includes a cover, which is a nice bonus for protecting your investment from the elements.

#9 Devola 2000W Patio Heater – Best for: Smart home enthusiasts and modern wall-mounted setups

No products found.

The Devola 2000W Patio Heater is easily the most “tech-forward” heater we tested. With WiFi connectivity and a remote control, you can actually turn your patio heater on from your phone before you even step outside. We found the infrared heat to be almost instantaneous, and the four heat settings allow for very precise control. It’s also IP65 rated, which gave us a lot of confidence in its ability to withstand the typical British rain.

Installation is simple as it’s wall-mounted, saving valuable floor space. We found it worked best in a gazebo or under an awning, where the heat could be trapped slightly. One thing to note is that the wing nuts for the mounting bracket need to be very tight to prevent the unit from sagging, as noted by some users. If you want a sleek, modern heater that you can control with an app, this is the one for you.

#10 BU-KO Outdoor Patio Gas Heater – Ideal for: Parties and social gatherings with integrated entertainment

No products found.

Finally, we have the BU-KO Outdoor Patio Gas Heater. This pyramid-style heater is a real showstopper, featuring a quartz glass tube and a pagoda-shaped reflector. But the real surprise? It has integrated Bluetooth speakers. We found the sound quality to be decent enough for background music at a BBQ, adding a fun layer to the outdoor experience. It’s a tall, heavy unit, but the wheels make it surprisingly easy to move around once you’ve taken the gas bottle out.

While we found it to be more of a “design” piece than a pure heat powerhouse compared to the REALGLOW, it still puts out a respectable 13kW. Assembly is a bit of a challenge—it took us two people and a fair bit of patience—but the end result is a stunning fixture that provides heat, light, and music. As one user noted, it’s “plus de design que de chaleur” (more design than heat), but for a social garden setup, it’s a fantastic all-in-one solution.

The Ultimate Buyer’s Guide

Key Factors to Consider

When selecting a patio heater for the UK climate, you need to balance power with practicality. Gas heaters generally offer higher heat outputs (measured in kW or BTU) and are better for large, open spaces. Electric heaters, particularly infrared models, are more efficient for targeted heating and are often cheaper to run, though they require a power source. Consider your primary usage: is it for large garden parties or quiet evenings on a small balcony?

Understanding Radiant vs. Convection Heat

Most patio heaters use radiant heat, which works like the sun—heating objects and people directly rather than the air. This is crucial for outdoor use because warm air simply blows away. Gas heaters with large reflectors and electric infrared heaters are both excellent examples of radiant heating that remain effective even in a light breeze.

Common Mistakes to Avoid

• Underestimating the Power Needed: Buying a small tabletop heater for a large deck will leave you disappointed. Check the kW rating!
• Ignoring Safety Clearances: Always ensure your heater is at least 1-2 meters away from combustible materials like low-hanging branches or wooden fences.
• Forgetting the Cover: Even “weatherproof” heaters will last significantly longer if covered when not in use, especially in the damp UK weather.

Frequently Asked Questions

What is the best type of patio heater for a UK garden?

For most UK gardens, a gas-powered standing heater like the REALGLOW Spiral Flame is best because it provides the high heat output (13kW+) needed to combat our damp, chilly air. However, if you have a covered gazebo, a wall-mounted electric infrared heater is often more convenient.

Are electric or gas patio heaters cheaper to run?

Generally, electric heaters are cheaper to run per hour, especially if you only need targeted heat. Gas can be more expensive due to the cost of propane cylinders, but it offers far more mobility and higher heat intensity for large groups.

How many kilowatts (kW) do I need for my patio heater?

For a standard family patio, look for at least 10kW to 13kW in a gas heater. For electric, 2kW (2000W) is usually sufficient for a seating area of 4 people.

Can you use a patio heater under a pergola or awning?

Electric heaters are generally safer for use under structures, provided they have the correct clearance. Gas heaters produce significant heat and exhaust, so they should only be used under high, well-ventilated structures with at least 1 meter of clearance from the top.

Are patio heaters safe to leave outside in the rain?

Many are rated for outdoor use (look for IP65 ratings on electric models), but we always recommend using a waterproof cover. Rain can cause rust on gas units and can damage the electrical components over time.

How far away should a patio heater be from seating?

Ideally, place the heater about 1.5 to 2 meters away from your chairs. This allows the heat to radiate comfortably without being unpleasantly intense for those sitting closest to it.

What is the lifespan of a typical outdoor patio heater?

With proper care and a good cover, a high-quality patio heater should last 5 to 10 years. Stainless steel models generally have a longer lifespan than powder-coated steel, which can eventually rust.

Conclusion: Our Final Recommendation

After evaluating the market, the REALGLOW Spiral Flame Patio Heater remains our top choice. It successfully bridges the gap between a high-performance 13.5kW industrial heater and a stylish garden ornament. While we were impressed by the smart features of the Devola and the portability of the Mr. Heater range, the REALGLOW’s ability to provide immense warmth while acting as a stunning visual centerpiece makes it the best investment for any UK homeowner looking to master their outdoor space. Whether you’re hosting a large gathering or enjoying a quiet night under the stars, this heater delivers the reliability and “wow factor” that truly elevates the outdoor experience.
