The heat is now because so within approximately one minute. While my wife earlier in the morning the heater started in the bathroom and then first went for a coffee, she now turns the device that hangs at shoulder height on the wall and immediately felt comfortable, simply because the warm radiation heats it immediately and do not wait must, until the whole room is warm. Since the device on the back barely heated, a wall mounting is not an issue.
The same is true for me in the study. Where previously generated the heater at 2000W right herb lies, this distributed in space dust, causing noise and an uncomfortable dry air, I now have a setting enough to 500W and I have it instantly warm. In the study, the device is in use 16 hours a day (two exterior walls, a wall to an unheated space) and as the very well-functioning temperature setting affects positively and energy saving.
The third device is the guest room in the attic, is so rarely used and should rather bring the room to a comfortable temperature for sleeping. Here the Duracraft needs naturally longer and should be more attuned to the 1500W-stage. But that creates the unit, although not quite as fast as a fan heater. You have to know for what you want to use that machine halt.
Important before start: In the first hour of the new device stinks quite unpleasant, so best let evaporate for 60 minutes in an unused space / garage at level 2 (1000W) in front of use in residential areas first.
