My copy is in our bathroom, so you can save yourself the long heating up on the heating. 5 min. At full power enough to get the bathroom relatively warm.
What moved me to buy this fan, was the promised "Silence" function that there is indeed. Unfortunately, these works almost too well, so it's already happened to me 2 times that I've forgotten to turn off the fan, because you just did not hear him. Yes, is my own fault and I chalk the device not to;) (I also have a vent in the bathroom, which drowned out the noise of the heater by far)
Otherwise there is not much to say. Performance is a maximum of 2000 watts, then you hear the fan working but clearly or in Silence mode with 1000 watts.
At the beginning of the good piece smelled something strange. But after a few days, sets the whole. Every now and then something comes smell every now and then from the device, but this is simply the accumulated dust of burns. Have another fan also.
Therefore, clear recommendation for people who like it warm and quiet.
