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.

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.

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.

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.

Wattage

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.

Size

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.

Timer

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.

Thermostat

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.

Display

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.

Portability

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.

Conclusion

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.
