Buy from Amazon.co.uk

De'Longhi Dragon 4 TRD41025T Oil Filled Radiator

The De’Longhi Dragon 4 TRD41025T Oil Filled Radiator boasts a new cell design that guarantees to warm a room up 25% faster than the traditional fin-designed models. This stainless steel radiator has a power output of 2.5kW and this is adequate to heat up large rooms of up to a very impressive 75m2. Larger rooms than this will require two or more of these radiators to warm up the space effectively, that being said, a 75m2 room is a big room, even in a large detached house. Its stainless steel frame is durable and it has been given a white finish that will easily blend in with your décor.

In order to use the radiator through the different seasons, adjustable heat settings are important. You can regulate how much heat is dispersed throughout the room by adjusting the dial. You can use the lowest heat setting (which has a power output of 1100W) during summer or use the maximum output for cold winter/autumn days. An interesting feature of this model is the Eco-function. This feature allows the radiator to automatically adjust the heat according to the surrounding environment, therefore, saving energy.

The 17.5kg radiator comes with a thermostat and a 24-hour timer. The thermostat keeps the room at a consistent temperature while the timer allows you to set what time you want the radiator to run. This oil filled radiator also possesses a frost protection feature that prevents the temperature from dropping too low. You will find that the wheels and handle are convenient when you move the radiator from one room to the next or move to storage over the summer. 

If the model is not in use, you can coil the cord around the cord storage provided and wheel it into storage. This good quality model operates silently and it comes with a very generous 10-year guarantee. That is adequate time to see if the radiator measures up to your standards and is longer than any other model we review. How’s that for peace of mind?!

The subtle elegant design and white finish of the radiator blend in easily with the surroundings.

This model would not only be suitable for large rooms but for small rooms as well. It is heavy to move around, but at least it comes with wheels. With time, the plastic smell the radiator produces on maximum heat will die down.

Overall, this is a quality radiator, it may have a few flaws but the performance is commendable. It comes with a 10-year guarantee and hence a large amount of confidence in the quality of the product.

The black coloured model produces enough heat to cover an area of 28m2 and this makes it perfect for small to medium-sized rooms.

You can set the temperature that you want by adjusting the thermostat which ranges from 5°C to 35°C.

Our recommendation

This model possesses 13 fins instead of 11 and it comes with an LED display which is a nice touch. Both models function well but this one has an edge in terms of a few features, like the display and the longer 6ft cable.

Performance-wise, this model is not bad at all. It has a few flaws but none that affect the overall performance of the radiator. For someone who needs a radiator to use occasionally, this model will do perfectly fine. It is not the most durable radiator you can purchase but it is reliable if well maintained.

Buyer’s Guide

Oil filled radiators have evolved over the years from the old models that we knew because they are less chunkier and some can even be mounted on the wall. Buying an oil filled radiator is not rocket science, in fact, it is pretty straightforward. This section shows the considerations you need to make to select the best oil filled radiator. These simple considerations will help you weed out the bad products from the outstanding ones. 

Area of coverage

The size of the room that needs heating will determine the right size of the radiator to buy. Manufacturers indicate the maximum size of the room the radiator can heat effectively so always confirm before purchase. A model like the De’Longhi Dragon 4 TRD41025T Radiator is the best oiled filled radiator for large rooms because it heats an area of 75m2.

Temperature settings & thermostat

Finding the right temperature is important for comfortability. A model that offers different heat settings gives the user more control over the heat produced according to seasonal weather. Radiators always come with a thermostat to help in temperature regulation. An accurate thermostat together with heat settings gives you the chance to find the perfect temperature for your house without running a huge electric bill.


A timer is an important feature if you need control over when the radiator is supposed to be active. The best oil filled radiator with timer functions is suitable, especially for those with conservatories. Many models on the market come with a 24/7 timer and some are more detailed than others. Select a radiator that has a timer that is easy to set up whether during the day or at night. You can know if the radiator you want is easy to set up by going through the product’s customer reviews.


The display in the control centre needs to be sizeable to prevent frustration when working the settings. A sizeable display that is backlit makes it easier for both the elderly and the young to set their preferred temperature. If you have eye problems then a sizeable display will be convenient during the day and at night. Also, confirm if the display light can be dimmed out for those who are sensitive to light at night.

Safety features

Safety features like overheating protection and a tip-over switch are crucial in preventing accidents. Overheating protection is a common feature in all types of heaters because, without it, the radiators might just melt from the heat they produce. If you have children and pets running around, the tip-over switch prevents the radiator from working when knocked over. This safety feature prevents harm to the user and the device itself.


Your budget controls the quality of the radiator that you will get. If you spend little money then you will have to bear the consequences of a cheap radiator which is usually a quality issue and has fewer features. While we are not saying that you spend your entire savings, we are saying that you need to make a considerable investment if you want a durable heater. If you just need a heater for temporary use then you can spend as much as you can spare. Those who want radiators for everyday use will have to cough up more money to get a reliable model.


Are you sensitive to noise or do you have a baby around? If you don’t want a loud radiator disturbing your child’s sleep then you need a quiet running model like the Mill 99407 Oil Filled Radiator Heater. Radiators that remove loud clicking noises can be used in areas like the conservatory where there is no one to disturb. Alternatively, you can let the radiator run during the day and shut it off at night so that you can get an undisturbed sleep.


Sleep better knowing that the money you spent did not go down the drain. A warranty assures you that the product will at least work effectively for some years. If you buy a product with a warranty you are guaranteed solutions just in case the radiator has manufacturing flaws. If you get a model like our best pick that offers a 10-year warranty, you can relax for the years to come.

Mobility & storage

Oil filled radiators are not as light as the convection heaters and because of this wheels are needed. Wheels and a handle make it easier to move the radiator around from room to room. Some models lack handles which will force you to use up muscle power in moving the radiator without it toppling over. 

Final Conclusion

Have you spotted an oil filled radiator that you like? If so we are glad. If not, then worry not because there are thousands of heaters on the market. Take your time and eventually, you will get the best oil filled radiator for large rooms if that is what you are looking for. 

Before you go, you might want to check the De’Longhi Dragon 4 TRD41025T Oil Filled Radiator again. This model will not fail you and there are plenty of positive customer reviews to prove so. It effectively warms both small and large rooms and it has a long 10-year warranty.

If that model is too large for you then consider the VonHaus 2500W/2.5KW Oil Filled Radiator which is smaller and costs less.

With that being said, we hope that you at least have an inkling of what to look for in a suitable oil filled radiator. We wish you all the luck as you navigate the marketplace.
