Good performance in mind, but electricity costs

The warm air flows in Level 1 really out of only the right half of the top slots. Nevertheless, the heating power is quite good. In my 20sqm space can be felt after some time the heat in the lowest level.

I have measured the power consumption: Level 1 approx 750W, level 2 about 1100W, level 3 about 1750W. In Level 1 that are perfect for me at present about 20Cent per kWh 15 cents per hour, therefore at level 3 already about 50 cents an hour.

So with the heat output I am very happy for the cheap price of the device. The electricity costs should be doing but still not lose sight of. If I use two devices in the home, some Euros come together quickly as a day.
