1. De’Longhi Dragon 4 TRD40820T (Editor’s Choice)

DeLonghi Dragon 4 TRD40820TIf you need a fast and effective heater for a medium-sized room, up to 60 metres cubed, then take a look at this De’Longhi Dragon 4 model.

It is 2,000 watts, ideal for average-sized household rooms, with three heat settings allowing you to keep your room heated just as you like it while reducing power consumption. Note that unlike some other Dragon 4 models, this one does not feature an eco setting. However, it does benefit from the Dragon 4 “chimney” effect design with large fins that channel cold air through the hottest parts for rapid heating.

This heater’s dimensions are 44 x 16 x 65 cm. Complete with an adjustable thermostat and a manual 24-hour timer, this radiator has everything you need to keep your surroundings cosy and warm all winter long or during any cold snap. Just be aware that it does smell quite strongly when new, although this will eventually fade. Also, the power cord could be longer.

However, with its integrated carry handgrip and easy-roll wheels, you won’t have any difficulty relocating this portable radiator near your power sockets.


  • 2,000 watts
  • Three heat settings
  • “Chimney” effect accelerated heating

The Warmlite 2000 Watt oil filled radiator comes in both a white and off white colour. With dimensions of 40.5 x 62 x 24 cm, it has 3 power settings so you can choose between 800, 1200, or 2000 watts of power usage. In addition, it has an adjustable thermostat with precise temperature indicators located on the front enabling accurate temperature regulation.

The base of this Warmlite radiator features rolling castor wheels for easy manoeuvrability. A 24-hour timer and an overheat shutoff function allow you to feel confident about safety during use. The timer also allows you to sleep with it on. It comes with a 1-year warranty but if you register it online you can extend it to two years.

Unfortunately, the Warmlite 2000 Watt oil-filled radiator is not designed for larger spaces but it will perform well in smaller spaces. Also, it will most likely emit an unpleasant odour initially so you may want to run it for a few hours in the garage or an unused room before heating a common area.

This portable oil filled radiator also features easy-roll wheels and a carry handgrip, so you can move it around as needed without any difficulty. It would be something that you may need to do more than with other models since the power cord is fairly short. This heater gives off a fairly unpleasant smell when new and, unfortunately, the instructions are rather poor.

It also has three heating power settings so you can reduce its electrical consumption when temperatures are milder. Its dimensions are 51.9 x 21.8 x 64 cm.

Unfortunately, the power cord is a little short, something that is exacerbated by its location on the unit. Also, there are no batteries included for the remote control, so be sure to order some with your purchase. While the timer is an extremely useful function, bear in mind that it cannot be used to set specific times in the day to come on and off.

However, thanks to its remote control operation and useful child lock function, this model stands out from others available on the market and makes a great choice for homes with young children.

To help ensure safety, an emergency cut off activates if the device ever accidentally tips over or overheats. The Schallen Fin 6 also features a 1.5-metre power cable and comes with a 1-year warranty backing the product’s craftsmanship.

Its dimensions are 37 x 13.7x 28 cm.

While this mini heater is recommended as being suitable for rooms up to eight metres cubed, you may find that at just 800 watts, that it is not powerful enough for all but the smallest of spaces. Also, while it is easy to pick up, bear in mind that it does not have any wheels, so you will need to be able to pick it up to change location.

The round the clock timer is highly practical, allowing you to set your heater to come on at the times when you need it. You can also use the adjustable thermostat to keep your surroundings at your desired temperature. Its dimensions are 50 x 24 x 62 cm.

On the downside, this heater’s wheel mounting brackets are a little thin and may not stand up to years of heavy use. The timer is a little complex to set up, although, with practise, it becomes easier. Also, the provided instructions are overly complicated and don’t offer much assistance.

If you are looking for an oil filled radiator that is easy to move around, this makes a great choice. It has a slim design for easy storage.

Are Oil Filled Radiators Economical?

man warming up his hand on oil heaterIf you are considering purchasing a new radiator, you are probably wondering, are oil filled radiators efficient?

Unlike bar or fan heaters, oil-filled radiators are much more economical to run. They transfer 100% of electricity into heat and make use of convection to warm your entire room, so no energy is wasted. What’s more, they also continue to radiate heat after being turned off.

Quick to heat up, with a fin design that makes for accelerated airflow, oil-filled radiators are a low-cost and efficient way to heat your home. Depending on your rates, an oil-filled radiator could cost as little as 13p an hour to run.

How to Choose The Best Oil Filled Radiator

When choosing a new oil-filled radiator, there are various features that you need to look out for to ensure that you pick the very best model for your needs.

Here are some of the main features to bear in mind.


Always pay attention to the wattage of your oil-filled radiator.

The higher the wattage, the more electrical power your radiator will be able to convert to heat. Higher wattage radiators are more suitable for larger rooms, whereas low wattage radiators will be more suitable for smaller rooms and will use less electricity.

If you are looking for an oil-filled radiator to use in various differently sized rooms in your home, purchasing one with multiple heat settings is the best option. It’s a great way to reduce running costs in smaller rooms while retaining maximum wattage for larger rooms. 2,500 watts is a popular wattage for medium to large rooms.


When reading through our oil filled heater reviews, pay attention to the number of fins and the size of each model.

The greater the surface area, the larger the fins, the more air that can be heated simultaneously. This means that your room will heat up faster at no additional cost.

For larger rooms, bigger radiators with more fins are the best oil heater to go for.


The best oil heaters have timers. These are an extremely useful function to have, allowing you to set your heater to come on or to turn itself off without requiring your intervention. Before purchasing, pay close attention to the type of timer that is available for your model.

Some feature 24-hour timers that can be programmed to come on for specific periods, for example, between six and eight am. This kind of timer allows you to preset your radiator to heat your room at a time when you know that you will want to have it on.

Other types of timer feature a countdown system, where you set your timer to turn itself off after so many hours, or to come on after so many hours. Consider which system would be of most use to you before making your final decision.


Thermostats are a great way to save energy and money. Set your thermostat to a comfortable temperature, and your oil filled radiator will turn itself on and off as needed to reach and maintain that temperature.

Some thermostats can be set to a specific temperature displayed in degrees. Others use a dial with graphics representing various levels of heat.

Heat Settings

The best oil filled radiators have several different settings, such as eco, anti-frost, or fast heating.

In most cases, you can often set your radiator to run similarly without a specific setting. However, having a dedicated mode does make it much more convenient and saves you from having to alter multiple settings.


Modern radiators often feature LED screens. They can be useful for easy to read information such as the temperature and whether you have a timer or thermostat activated.

However, some people prefer manual controls and dials, so it comes down to a matter of personal preference.


Some oil filled radiators can be fairly heavy. If you need to move your oil filled radiator between rooms regularly, you should check that your model comes with castors and carry handle for extra portability.


After reading our reviews, you should have a clear idea of which model is the best oil filled radiator for your needs.

All the models we have seen are great options to keep your home warm and comfortable, but our overall favourite is the De’Longhi Dragon 4 TRD40820T.

With an adjustable thermostat and a 24-hour timer, you will easily be able to keep each room of your home at your desired temperature. Meanwhile, the ‘chimney’ effect means it heats up faster just in case you forget to set it to come on for when you get home. We love that its stylish design, carry handle and wheels, will not only make this radiator look great in any room of your home, but means you can easily get it there, too.

Thanks to its 2kW power output, it is capable of heating rooms of up to 60m³ so is perfect for most rooms in your home and there’s really no reason why this shouldn’t be the top pick from the ones we have looked at today.
