Through two outer walls a room is simply not heated hot enough. This rollable radiator (filled with oil) is the solution. It is my view of the construction ago rather harmless (also TÜV ... but should still be supervised in the instructions), practical to use and well finished - at a fair price (38 EUR). The radiator can be quickly rolled to the desired location (and the roles could be quite easy to grow). He is at a high level quickly hot and later after stopping the unit keeps the heat for a while. In between, the unit turns off, unless a specific heat intensity has been reached, and will later also from alone again. Due to the current high cost of electricity I have ensured that the device can also be operated with "only" 600 Watts. You can adjust the temperature continuously and also select three strength levels. An indicator light provides a visual reminder, if you have the device not completely issued (this one must turn to 2 Set to zero: the temperature selector and the heating stage). Downstairs there is for the cord still reeling when you have not the equipment. A really good acquisition - finally pleasant living warmth in the winter !!
