EDIT: On second thought maybe there is a 400W heating element in the fan? But that wasn't included in the radiator's heating power on the tag

Poland I don't know if its still cold there but you should try the black stuff in the sun for a heater!
I used to heat my apartment like that.you need alot of sun though.
