Its slim design also fits nicely in tighter spaces like under desks.

Oil radiators typically produce minimal sound, which makes this heater suitable for bedrooms or workspaces. The size and weight mean it is not the lightest heater on the market, so it may be less ideal for those seeking an ultra-compact or very lightweight option. For typical home or office use, this model strikes a good balance between power, safety, and portability. This Pro Breeze model suits those who want a dependable, easy-to-use heater that provides even warmth over time without worrying about safety, and who value energy efficiency and the option to move the heater around as needed.

You can easily control the warmth thanks to its adjustable thermostat and three heat settings (1000W, 1500W, and 2500W). The built-in 24-hour timer is a nice touch for saving energy by scheduling when the heater runs.

Safety is well covered with features like tip-over protection, overheat shutoff, and built-in heat protection, so it’s suitable even for rooms with children or bathrooms where safety is crucial. The heater is also designed to be portable despite its size, with four wheels, a carry handle, and cable tidy, making it easy to move between rooms and store away.

Weighing about 9.3 kg and having a slim profile, it fits easily in smaller spaces like under a desk or in a corner. For steady, low-maintenance heat with good safety and energy-saving options, this radiator is a dependable pick. If you need very fast heat or outdoor use, you might want to consider other types of heaters.

The De'Longhi Dragon 4 TRD41025T is a well-regarded oil-filled radiator ideal for indoor use, offering efficient heating with its 2.5 kW heat output. Users can choose from three heat settings, including a medium setting of 1400 watts and a minimum of 1100 watts, which allows for flexible temperature control.

A standout feature is its portability, thanks to pre-assembled easy wheels and a carry handle, making it simple to move between rooms. This device is designed with safety in mind, though specific safety features aren't detailed, the long 10-year warranty suggests durability and reliability. The elegant white design is aesthetically pleasing, allowing it to blend seamlessly with various home decors.

However, the radiator's substantial weight of 17.52 kg may make it less convenient for some users when moving it, despite the wheels and handle. As an indoor-only unit, it lacks versatility for outdoor use, which might limit its appeal for those seeking a multipurpose heater. Furthermore, while the noise level is not specified, oil-filled radiators are generally quiet, benefiting users looking for a heater that doesn’t disturb their environment.

In conclusion, the De'Longhi Dragon 4 is well-suited for indoor spaces needing a powerful, flexible heating solution with easy portability, though its weight and single-purpose usage might be points to consider for potential buyers.
