 What is the best patio heater type?  

Most patio heaters you can buy are electric. They need to be plugged in, but they heat you with infrared light which is more efficient because it heats objects directly instead of the air in the immediate surrounding area. Gas patio heaters are more portable because they have fuel on-board, but because they’re convective they are less energy efficient. 

They won’t heat you directly but instead heat the air around you. For the best patio heater for you, keep on reading, and when you’re done, take a look at the best chimineas

Specifications
Best for: Infrared
Type: Freestanding
Power: 2000W
Fuel: Electric
Heat type: Infrared
Reasons to buy
+Powerful+Minimal design+Energy efficient+Five power levels+Remote control
Reasons to avoid
-Design isn’t 360-An expensive choice

Packing 2,000W of power, the OPRANIC 2KW Electric Patio Heater is energy efficient and safe. This electric heater uses infrared to heat you directly, instead of heating the area around you, which is an energy-efficient feature that will cut down on costs and wasted heat.

Other great features include the column design, which will warm you you from top to bottom, and the remote control. That means there's no need to get up and switch off the heater when you're all warm and toasty. You’ll find that it’s great for evenings where you’re sat outside because it’s perfectly sized to warm up your entire body when you’re seated, including legs. 

This heater is a metre tall, but it doesn’t heat 360-degrees around it. For smaller groups where you can all position yourselves in front of the OPRANIC 2KW Electric Patio Heater, it's a good choice.

Type: Portable
Power: 800w
Fuel: Electric
Heat type: Carbon lamp
Reasons to buy
+Designed to be portable+Compact frame+Three heat settings
Reasons to avoid
-Not the most powerful

While 800w isn't as powerful as some of the best patio heaters in this guide, the Herschel Havana Portable Electric Patio Heater is a perfect choice for seated events, under tables or even on tabletops. 

It's 65cm high and has one heat setting, which is fine because 800 watts is about the right temperature for most events, but not as versatile as some of the more expensive options in our guide.

4. Dellonda Freestanding Gas Patio Heater

Best gas patio heater: a powerful freestanding choice

Specifications
Best for: Gas
Type: Freestanding
Fuel: Gas
Heat type: Direct
Reasons to buy
+Variable controls+Portable+2.27m tall
Reasons to avoid
-Gas is inefficient

Many prefer a gas patio heater to the best electric options. This is largely because they're cordless, meaning you can place the heater right at the foot of the patio without worrying about tripping over cords. 

The Dellonda Propane Gas Pyramid Patio Heater is a freestanding and generously sized option. Storage when not in use could be tricky as it's over two metres tall, but if you have the space it's a top choice. 

Safety features include a variable heat outlet and a tip-over switch that automatically turns off the heater if it tilts. The metal reflector directs the heat downwards and towards you.

Best for: Overhead
Type: Freestanding
Power: 2000W
Fuel: Electricity
Heat type: Infared
Reasons to buy
+Discreet design+Adjustable head and height+Three heat settings
Reasons to avoid
-Corded

The Heatlab 2kW Outdoor Freestanding Electric Quartz Bulb Garden Patio Heaters is a great choice for most gardens. It can be adjusted to run at 650W, 1350W, or 2000W, meaning you can leave it running in the background for some added warmth without overheating if you wish. 

This patio heater is freestanding, and it comes with a sturdy base that’s designed to protect you from accidents such as tipping. The head can also be adjusted by 45 degrees and the height can be adjusted from 5ft 8 to 6 ft 10. 

It’s not the most versatile in terms of all-around coverage, and if you’re entertaining a large group then some may feel the warmth of this patio heater more than others because it doesn’t offer a 360-heat or any rotating features.

-Not the most powerful

Unique among our picks is this wall mounted patio heater, a clever space-saving solution for small patios, decks or balconies. That it’s electric also means you don’t run the risk of ending the party early by running out of power, as can happen with gas patio heaters – unless there’s a power cut, of course! The remote control function is very useful here – no need to try and reach the switch if you've mounted it higher up. We do wish there was an instruction manual included, although installation is fairly straightforward even without one.

How to buy the best patio heater

Our recommended retailers for the best patio heaters

When it comes to choosing the best patio heater to suit your outdoor space – as well as your requirements – there are a few factors worth bearing in mind. These include:

Size

If you only have a small area to heat, such as a petite patio or small balcony, then you don’t have to go for a large freestanding model. Try, instead, a tabletop patio heater, which looks a little like a bedside lamp and doesn’t give out as much heat so you won’t cook in close quarters. 

Owners of small gardens will also be cheered, no doubt, to hear that wall-mounted patio heaters are another viable and surprisingly adaptable option, letting you direct the heat upwards or downwards by adjusting the vent.

The flipside of this, of course, is the aforementioned freestanding patio heater. It will take up more space, but if you have a large patio or deck that offers enough space for it, chances are there’s a lot more area to heat, so you’ll need the extra power they can dish out. 

Fuel type

The main difference between gas and electric patio heaters is how clean they run. Electric heaters pack less of a punch than their gas alternatives, but they do so with a far more modest carbon footprint thanks to their infrared technology. Electric patio heaters aren’t an option for everyone though, because many of them need to be plugged in.

The final consideration you need to make is the type of fuel your patio heater will use. While the easiest way to fuel a patio heater is with electricity, you may not have an external outlet at your disposal, or be nervous about the plug being exposed to the elements. The other options are natural gas and propane, the latter being the most common.
