Best Oil Filled Radiators to Keep You Warm This Winter (2021)

With its sleek, compact looks, the De’Longhi Dragon 4 will work well in most rooms and with a 2kW output, can create a decent amount of heat. And with its neat ‘chimney effect’ design, that heat gets distributed around the whole room. By channelling cold air through the hottest part of the radiator to accelerate heating, the result is an even heat that warms up faster than more traditional oil heater designs. 

You get a decent amount of tech spec for the mid to top range price, including an anti-frost device and 24-hour timer. You also have three heat levels and an adjustable thermostat to put you in control. Add in safety features including an overheat cut out, a cable tidy and sturdy wheels and you can use this radiator anywhere in your home. 

From an aesthetic point of view, the Dragon 4 looks good too, with its brilliant white finish and slim, elegant design. A great addition to any home that looks as good as it heats. 

For the price, this is a well-built and efficient oil filled radiator, which powers out plenty of heat, thanks to its 2500W rating. And the 11 fin panels ensure the heat is evenly generated to warm through your whole room. This is also a good-sized radiator that feels substantial yet is compact enough to have by your desk or chair. And the easy roll castors mean getting the Pro Breeze around is, well, a breeze! There’s a nice bit of temperature control too, as you get three heat settings plus a fully adjustable thermostat and for when you want your room warm when you get home, a handy 24-hour timer. It has the key safety features you would expect, including tip-over switch and automatic thermal shut off should things get too heated. All-in-all a solidly performing oil filled electric heater, although an extra handle would make it a little easier to move around. 

Compact and bijou is a good way to describe this mini oil filled radiator and its smaller size is perfect for smaller spaces. And, as it is a lower wattage – 650W – it is also a good choice for caravans and campervans as it works well with campsite electrical supplies.  

While it doesn’t push out sufficient heat for larger rooms, this neat heater is a nice addition for when you need to take the edge of a small room or as a back-up to boost the heat. It features five fins to evenly distribute the warmth it generates and has an adjustable thermostat to fine tune the temperature. And an overheat protection feature means you can be sure your oil filled electric radiator won’t get too hot. There are no wheels on this portable oil filled heater but there is a sizable top handle, and, at just over 2.6 kg, the whole unit is lightweight and easy to carry around. 

PureMate have come up with a substantial 2500W model with this 11-finned oil filled radiator, making it a versatile choice for any home. It is not the cheapest in our review, but you get a lot of decent heat for your money and it can also be used in a garage to keep the chill away on colder days. The design is slim and attractive and with four castor wheels and an end handle, you can easily move it around. There are three heat settings and an adjustable thermostat so you can fine-tune the warmth it generates. And you can set when it comes on or goes off, thanks to the easy to use 24-hour timer. You get the standard safety features too, including tip over switch, which is handy as this is a tall radiator, and an auto thermal shut off. At over 11 kg, this is one of the heavyweights in our best oil filled radiators review, but it looks and feels as if it has been built to last. 

The Russell Hobbs five fin oil radiator is another compact unit that is sized for smaller rooms and spaces of up to 10m2. And the sleek black design is attractive and should work with most decors. At 650W, this doesn’t have the biggest output but it is sufficient, and you get three settings so you can adjust the heat. There is also a thermostat, so the unit switches off once it reaches the desired temperature and the five fins help to radiate the heat where it is needed. This oil filled radiator requires some assembly, but the instructions are clear to follow. And once in place, the small castors work well, backed up by an integrated handle so you can easily move the radiator from room to room. 

Sized for spaces up to 20m2, this is a larger electric oil filled radiator that has a 1500 output and uses its seven slim fins to quickly distribute heat around your room. We think this radiator is smart enough for the office as well as the home and as it is portable, can go wherever you need an extra boost of heat. The three heat settings cover a 600-1500W range, and the adjustable thermostat means you can set your ideal room temperature. However, there is no timer which is a shame, as it would make this a really versatile oil filled radiator to own. But it does have the necessary safety features you would expect, including a tip over safety stich. For the size, this is a nice and lightweight portable electric heater, boosted by four castors so you can easily move it around and would make a good back up when you need a little extra warmth and cosiness in your home. 

The squat design of the De’Longhi Nano gives this small electric oil filled radiator a robust look and is sturdy enough to have under your desk or beside your favourite chair. And it has been designed to heat up rapidly, so you get the warm benefits sooner. As the smallest entry in our best oil filled radiator review, it also has the lowest wattage, coming in at 500W. But the manufacturer says this is suitable for rooms up to 15 cubic metres. But pop it into a smaller space and you will certainly feel nice and toasty. And should the temperature in your room drop to icy below 5 degree levels, then the anti-frost kicks in and the automatic thermostat will turn your mini oil filled radiator on. The thermostat is also adjustable so you can dial the heat up or down and thanks to its size and large carry handle, this is a radiator you can easily take on your travels to keep you warm. 

Coming in at near the top end of our best oil filled radiator review budget, the Dimplex is a powerful heater that is ideal for a bedroom as it has an almost silent operation. This model is sizeable, but the design keeps it slimline, and the radiator body is made from quality steel. This does add to the weight, but you do get four easy roll castor wheels and an end handle so you can safely move it around.

The Dimplex also has the functionality you would expect from an oil filled radiator in its price bracket, including an adjustable thermostat which includes a frost setting and a fully programmable 24-hour timer. There’s also a choice of two heat settings and a safety cut out should the unit start to overheat. As the radiator is on the tall, slim side, it is good to see a safety tilt switch to keep everything safe should the heater get knocked over. This model is also the best oil filled radiator when it comes warranty as it comes with a three-year guarantee as standard.
