1800w is about the same as many blow dryers and and most household space heaters.  At 120v it is just 15 amps which what most household outlets support.  You would not want a lot of other stuff running on the same circuit while you use it, of course, but if that is the excuse you need to put in another circuit I will back you up.  😀
