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. The design of this DeLonghi heater also features a carry handle that allows you easily and comfortably to carry off the heater to a designated place in your home. Oil-filled radiator heaters are non-directional in their heat, which means you don't feel their benefit instantly but they soon fill the room. 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. The fins on the radiator distributed the heat quickly, and perhaps more importantly, kept fingers away from the really hot parts between the radiator blades.

There is no way to set it to trigger at a certain time, though: it only works as an offset of the current time.

The DeLonghi Dragon 4 is larger than many of the basic six or seven fin oil-filled models, measuring around 14 inches long, 6. But neither of these things surprised us – when people are as happy with a purchase as folks seem to be with the Dragon, they simply find less to complain about.
