They come in a range of sizes and colours but are usually characterised by the metal fins that distribute heat. 

Ideal for most sized rooms and easily manoeuvrable, oil filled radiators are a solid choice to get you through the cold winter months.

Best Overall – De’Longhi Dragon 4 Oil Filled Radiator 

Check Price on Amazon Buy Direct

A significant upgrade from the already great Dragon 3, De’Longhi’s Dragon 4 Oil Filled Radiator is our top pick. 

It has a range of heat settings available. The lowest of which puts out 1100 watts, while the medium option is 1400W. The highest setting will not often be needed as it can put out a maximum of 2500W.

Although at full power this radiator will get up to temperature very quickly and create a huge amount of heat, it’s expensive to run when compared with the lower settings. 

Designed to work best in a room measuring 75m², the Dragon 4 uses an enhanced chimney effect to quickly heat the entire area.

The thermostat and power output are simple to set with the manual dials, while the 24-hour mechanical timer allows you to easily program the radiator’s on and off times. 

The Dragon 4’s power cable is only 1.37 metres which can make it a little challenging to position if you don’t have a conveniently placed plug socket but the 17.5kg radiator is easy to move thanks to the soft roll wheels and double carry handles. 

With its overheat shut off, it’s safe to leave this radiator on to keep you warm for hours on end. The anti-frost function can be used if you are planning on being out of the room for extended periods. 

De’Longhi have so much faith in their product that they offer a 10-year warranty as standard with the Dragon 4 Oil Filled Radiator!


  • 2500 watts maximum output
  • 24-hour timer
  • Inbuilt thermostat
  • 10-year warranty


  • Easy to move
  • Three different power settings
  • Heats a room quickly using its enhanced chimney effect


  • The power cable is a little shorter than the competition 

Bottom Line

The Dragon 4 Oil Filled Radiator from De’Longhi is a superb choice. It’s well built, reliable and comes with an amazing 10-year warranty. You’ll be hard-pressed to find a better option.

Runner Up – PureMate 2500W Oil Filled Radiator 

Check Price on Amazon

A great alternative oil filled radiator is the PureMate 2500W. It has a maximum power output of 2500W but there are also 1000W and 1500W settings which are far more economic to use.

The radiator includes a fully adjustable thermostat and 24-hour timer so you can get a room to your desired temperature. As well as this, the PureMate comes with a built-in overheat cut off and tip over shutdown so you can feel safe while using it!

As well as being able to heat a single room, this device is easily moveable thanks to the caster wheels and grab handles. It also weighs just 11kg.

The power cable is 1.5 metres long which is better than some of the competition but still a little short if you want to place the radiator in the middle of a room.


  • 2500W maximum output
  • 24-hour timer
  • Overheat and tip-over shut down
  • 12-month warranty


  • Three different heat settings

The seven fin version has a maximum power output of 1500W but can be turned down as low as 600W, which is much friendlier on your wallet.

Even used on its lowest setting, this oil filled radiator only takes a few minutes to start emitting heat and the inbuilt thermostat ensures the temperature doesn’t rise too high. In case anything goes wrong with the radiator, there is overheat and tip-over protection in place.

At less than 8kg, the Russell Hobbs radiator is easy to manoeuvre around the house using either the grab handles or smooth-rolling wheels. Its modern design is sure to fit in with your decor and it comes in two colour options: white or black. 

It performs best in rooms around 15m², so is ideal for smaller living rooms, bedrooms or offices.

As well as being available in two colours, this oil filled radiator is available in three size options, ranging from the small 5 fin version to the large 9 fin variant.

Designed for rooms around 20m² in size, this oil filled radiator works well in small living rooms, bedrooms or offices where the 1.5-metre cable is just long enough to not be too constricting. 

Although the manufacturer advises you don’t leave this radiator unattended for long periods, the automatic thermal shut off will stop it overheating while the inbuilt thermostat ensures it keeps a consistent temperature. 

Both the power output and temperature controls are easy to use by turning the dials to the appropriate position.

Coming with an inbuilt thermostat and overheat protection, this radiator can be used with confidence. It will keep a room to your desired temperature and will shut off should it get dangerously hot.

The timer allows the radiator to be switched on for a duration of up to 24hrs, after which it will automatically shut down. An eco-mode will moderate the heat to save power. 

The temperature can be set from 5C all the way up to 35C, which is suitable for all heating applications. Any previously used settings will be memorised for the next time the device is switched on.

Considerations When Buying an Oil-Filled Radiator


How you want to use your oil filled radiator will determine how portable you need it to be. If you plan on leaving it in one room then portability might not be something you’re worried about. However, if you want to move the radiator around your house, you’ll need to ensure it has wheels and decent grab handles.

The power cable length is also an important factor in how manoeuvrable your radiator is going to be. For example, if yours only has a 50cm cable attached, there will be very few places you can position it where it will still be close to a plug.


Realistically, unless a radiator fits in well with your current decor, you may find yourself hiding it away and not using it. With that in mind, it’s worth choosing a radiator that appeals to you aesthetically.

Some people will prefer the look of a slim radiator but it’s worth noting that different sized options come with pros and cons. Smaller oil filled radiators tend to heat up quicker than their larger siblings but also emit and retain far less heat.

Larger radiators can still produce a decent amount of warmth even after being switched off for 10-15 minutes. 

Power Output 

The power output of oil-filled radiators is measured in Watts. Anything less than 600W isn’t worth considering as they don’t put out much heat at all. Conversely, anything over 2000W can be expensive to use, especially if it’s turned up to the max. 

Small rooms or offices can usually be heated by a 600-800W heater whereas an average-sized living room would be better served by a 1500W machine. Large or particularly cold rooms will require a 2000W radiator but these can be pricey to run long term.

The most efficient way to use an oil-filled radiator is at a low setting. A 1500W heater used on its lowest setting is likely to be much more efficient than a 600W machine used on its highest. 


It’s possible to buy oil-filled radiators with programmable inbuilt timers. These allow you to set the radiator up once and as long as it remains plugged in, it’ll switch itself on and off at the desired times. These can come in the form of a digital screen or analogue dials but some radiators won’t have one at all. Keep this in mind when making your choice. 

Safety Features 

An important and often overlooked aspect of oil-filled radiators is their safety features. Ensure your radiator of choice comes with a well-rated thermostat and a good auto shut off feature to prevent overheating. 

A tilt switch, while not necessary, can be a great addition should you have kids or pets at home. This will automatically shut the radiator off should it be knocked over, preventing heat damage to the surrounding area as well as dramatically reducing the fire risk. 


While the De’Longhi Dragon 4 is certainly the best oil filled radiator we found, the PureMate 2500W is a close runner up. 

For the budget-conscious, the Russell Hobbs radiator is well priced and very reasonably priced to run. If you need to heat a large space, you won’t go far wrong with the Oypla radiator.
