A third wall borders nor to the hall, the with us on the ground floor and is quite cold in winter, because we have the front door almost directly in front of the nose and abkriegen the cold first. And among us is of course the cellar. (However, it also has benefits to live on the ground! ;-)) In really deep winter the bedroom is thus hardly really warm, even if the heating still so very thumps. It freezes himself under the covers even as a tailor. Since we had been looking for remedy, and this device is exactly what we needed: it is at once warm, the heat is pleasant and cozy and also very fast throughout the room felt, not only in the immediate vicinity of the heater.
During the first hours of operation you should install the server in a well-ventilated room, where you then best not staying for a while, because at first it developed some unpleasant odors. This is, however, very quickly. After that you have a really excellent and quiet heat dispenser, one can incidentally also be mounted on the wall. We have but apart from that, we also like to use it, as needed, sometimes somewhere other than the bedroom.
