this heater maxes the amount of heat you can get from a standard receptacle.  So dont try to operate something else like a hair dryer on the same circuit, or u will trip a breaker.  The unit is well designed, and heat does radiate around the coils better than I expected.   No loud fan like you are jused to, instead, just heat.  No super hot spots on the heater.  Delonghi engineers really know how to design a good looking product, as it appears quite high tech, but yet has old school mechanical controls.  
Excellent heater
