The heater has a cover (splash guard) and can therefore be used even in the bathroom, which makes sense because large or high rooms you can not heat it. Who, for example, lives in an old apartment, and therefore want to heat in a cool autumnal September transitional phase, is then reached with this heater is not much. For the power is then too expensive.
In the bathroom but perfectly usable> with the small heating stage. The large stage one does not need it.
