Using an electric heater on my electric bill?

I have a bet down on this one... I have a 'Holmes electric heater fan' I also have to pay the electric bill here at an apartment, so i'm thinking it uses alot of energy. When I turn it on, the lights dim for a sec, and brighten for a sec when off, kind of like a hair dryer. Does this use alot of electricity? noticably? the AC makes the electric bill sky high, but doesn't dim the lights...?
