The image on the Amazon site does not match the stated reference (missing the fan that you see on the manufacturer's website). In fact, it corresponds to the model Delonghi KH770925 (without "v"). The technical information in this site is rather curious: First, it shows the power of 2500W, 2000W then, and a little lower "maximum power: 2000-3000 W" while the manufacturer mentions with 2000 W, for its product KH770925 V in English "Fan heating element 500 W". Therefore, to indicate 2500W KH770925 version that does not contain this element seems abusive. Where does "the maximum 3000W power" remains a mystery. Amazon's site mentions 9 elements while on the KH770925 model I received there are 11. 9 elements correspond to KH770920 model. The dimensions given by Amazon on this page are not the same as another offering the same product (more expensive); ie = UTF8 & qid = 1382529108 & sr = 1-12 & keywords = DeLonghi These incomplete information and inconsistencies probably come from the manufacturer who provides the unit with information delivered could not be more basic. Only printed in Turkish, added to the fact, mentions the make and model radiator (!) On the other language versions such data is not. They are on the packing box, but largely only on the sticker indicating that the unit has been manufactured in China (which neither Delonhgi or Amazon do not specify). The packaging, he says - in German - a guarantee of 7 years, but I have seen anything like this on the websites of Amazon and Delonhgi or invoice Amazon says no warranty. The brochure mentions and shows the image of a timer for setting the operation of the device, but that timer is on "select models" that I did manage to find nowhere. The instructions on the operation of the device are limited to one A5 page (the second relates to the mounting of wheels that is already done in the factory and maintenance of the unit). There is no reason why there are three powers I, II and III, or how many Watt they correspond, or how the selection of one or the other influences the operation. The thermostat to the desired temperature is very confusing: "When the desired temperature is reached, slowly turn the thermostat counterclockwise to clockwise until the LED séteigne (or to 'click' indicating the position, but not beyond. ") It's nice, but how does one know when one has reached the desired temperature? The appliance thermometer reads positions from January to May, without specifying how many degrees they match. Could it 5,10,15,20,25 and 30 degrees Celsius? Nor is there said if the adjustment is final or whether to start over each time you have turned off or unplugged the appliance; nothing not explain what to do if we want to change this setting. As this is an extra heating, "the desired temperature" should match the one you want to have in the first room heated by another radiator fixed. The adjustment may take some time because it is then necessary that the room is at the desired temperature, and then we send down the power a bit to adjust the additional heat ... Finally, the electric heater will turn on when the room temperature goes down even if nobody is there and if we would be satisfied with a lower temperature. Certainly, the heaters in general and especially the combustion heaters should be equipped with a timer.
