When it comes to De'Longhi, the first thing that comes to mind is the coffee machine. With 23.9% global sales in the field of coffee machines, De'Longhi is the undisputed king. De'Longhi is not only world-renowned in the field of coffee machines, but also has a good reputation as an excellent Italian manufacturer of small household appliances, and its electric heater products are also of excellent quality.
 
De'Longhi TRD40615T oil heater is the first place in the evaluation group of The wirecutter large room, priced at 89 US dollars, or about 579 yuan. This product is designed with a number of De'Longhi patented technologies and is of excellent quality. According to the Wirecutter test, De'Longhi TRD40615T can increase the room temperature by 4°C and 7.4°C after one hour of use, respectively, with excellent heating performance. Its patented hot flue technology creates a chimney effect between the vents on the metal top cover and the internal heat trough, quickly heating and convection with the air, while maintaining a low surface temperature while maximizing heat release, making it safer to use. In the season when electric heaters are not needed, the patented design of the pulley can be used, it can rotate 360 degrees, can also be folded and stored, and it is extremely practical. The fly in the ointment is that TRD40615T is not equipped with a remote control, and there is no sales on domestic e-commerce platforms.
 
If you want to achieve fast and uniform heating in more space, the De'Longhi Extreme Warm Flow Series V551220T double-layer oil tin is fully suited to your needs, with the same heating flue technology and patented pulley technology as the TRD40615T, and the heating performance and portability are not inferior to TRD40615T. Not only that, but it has a larger number of tablets and more power, which can generate more heat under the same conditions, even for indoor areas of 20 square meters. V551220T double-layer oil tin in the traditional single-layer oil tin outside the addition of a layer of protection plate, to avoid direct contact with the heat dissipation oil tin when in use, the traditional single layer oil tin because the heat sink is directly exposed, so the temperature of the oil tin sheet can not be too high, generally not higher than 85 degrees, but the V551220T oil tin sheet is wrapped inside the oil tin, its temperature can be greater than 85 degrees Celsius, the heat dissipation is naturally greater. On the other hand, the heat of the ordinary single-layer oil tin will be directly dissipated to the surroundings when it is working, which can easily cause the embarrassing situation of "hot in the middle and cold all around", and the protective heat sink and heat convection hole added to the outside of this oil tin make the heat of the oil tin concentrate from the top and flow upward, and the heating is more uniform, which is also the origin of the chimney effect. At present, the price of V551220T on domestic e-commerce websites is 2380 yuan.
