De’Longhi’s Oil Column Heaters, with their tunnel construction design, ensure exceptional heating efficiency and performance. The unique setup features electric elements immersed in oil, producing radiant and convective heat that is not only effective but also enduring. This method guarantees a long-lasting warmth, making these heaters a standout choice for maintaining a comfortable room temperature.

The Dragon 4 model, in particular, showcases an exclusive fin design that significantly enhances the heater's radiant surface. This design promotes a chimney effect, which accelerates airflow and ensures even heat distribution throughout the room. The result is powerful warmth that transforms any space into a cosy haven.

Moreover, De’Longhi has integrated smart technology into these heaters to allow for efficient consumption and customisable comfort. The ECO Plus function optimises energy use by adjusting the heating output to the current room temperature, providing a greener solution to home heating. The user-friendly digital LED panel offers complete control over the heater’s operations, including temperature setting, power levels, and a 24-hour timer, ensuring that your heating preferences are met with precision and ease.

This a very effective heater
This Delonghi Dragon 4 oil heater is a very effective heater in a very large open area. Living in southern Victoria near the coast and its cold here and much colder than Melbourne for example. It’s an oil heater so takes some time to heat up but this is a large three room open area of 10 x 14 meters and it takes the chill off for sure. When the temperature drops the Aircon is the next option I prefer this in the interim. Good value for the benefits in my opinion.

Effective but noisy
This heater was awesome to start with, and still works really well but it’s become very noisy after a few weeks of use, it creaks and pops almost constantly.
