I received this radiator there a while, but I expected the cold comes to an opinion. So, contrary to the critics read above, there was no misunderstanding about the model or its characteristics. I was on the delonghi site for detailed specifications, and no surprises. The heater: its appearance is good, he is sober, and the thermostat / Wheels party does not fake. Orders: a graduated thermostat knob and two buttons control the two resistors, a 1000w, 1500w one. Once the heat reached the room, we quickly find the desired setting for the volume to be heated. Given the volume of the radiator, the heat dissipates.
Simply put: I think all radiators oil bath "walk" all the same (resistance, Joule heating, heat transfer fluid), but the quality of materials and the simplicity of this model makes it a good choice. If I remember correctly, it was announced to 70m3.
