First invented and developed by DeLonghi, and now often imitated, an oil-filled radiator heater is a radiant heater, similar in many ways to any other radiator heater, but with an important basic difference in design which allows it to be very efficient and also to output a deeply warming and wonderful feeling heat, which somehow feels better than what you get from so many other radiant heaters.

DeLonghi TRD40615E is an oil-filled radiant space heater that will impress you not only by its heating capabilities, but also with its beautiful design, quality, usability, and as well as safety features. Overheat Protection: If the indoor temperature rises above the allowable limit, then the overheating function will shut off the device immediately. This is extremely useful to prevent unwanted incidents. A noticeable odor is coming from the heater when it is used for the first time, which is also a common issue for every new heater. The odor will disappear after the first or second time of use.

Like the DeLonghi TRD40615E, this heater also offers 3 different heating modes, as I already mentioned, it uses1500 Watts when it sets to work in high mode, 900 Watts in medium mode and 600 Watts in low mode. Keep in mind this model also offers an efficient Eco mode of operation that will save both your electricity and your budget in the cold winter days. It can deliver 5120 BTUs of heat, enough to effectively heat any room of small or large size. In addition, it is quiet, safe to use, it has great portability and at the same time with its built-in ECO mode, it will reduce your electricity consumption and your budget. The heater provides the best results if it is used for small and medium rooms with a maximum of 144 square feet.

Oil Filled Space Heater | DeLonghi

As someone that works from home, I don't want to heat the whole house when I'm only in one room, so using an electric heater is ideal. I tried various heaters before this one but none that really did the job. I loved the look of the Vornado Glide but it just didn't have the staying power to stave off that sub-zero chill from my window and the sound of many of the tower units was too distracting. This is absolutely the nature of radiant heaters, though, even the best full-room heaters like this one, and if you can be patient and allow them a few hours to fully radiate heat into the room, you will see what wonders they are actually capable of.

This gives you a great deal of freedom in controlling not only the temperature in the room, but also you have control over your electricity consumption. You also control your budget at the same time, which is really useful especially in winter. Feature-wise, the Dragon 4 is very similar to the DeLonghi Radia S Eco, with the exception being the chimney fin panel design. This design not only looks more stylish but it does heat the room faster. People tend to be fiercely loyal to DeLonghi as a company, and to their products, and the heaters are no exception. Indeed, we see more repeat customers for DeLonghi space heaters than maybe any other company – even more remarkable considering that customers tend to have them for many years!
