the heater is not really loud but audible emphatically.
He has only a constant speed and the fan will not quite round.
The visuals are very well done, but at times just the living room to heat up in some cold corner during watching TV, this is me definitely too loud.
To heat an adjoining room maybe ok, but not for living rooms because the noise is too intrusive.
For my idea not optimal since I tät` me look elsewhere. Now have a Rowenta with "Silence level".
Now that's an announcement, no comparison to Steba.
