It's less than that, actually.  Total load is around 800 watts
(actually a bit less once it's warmed up IIRC), but that includes the
motor (probably not a big factor) and the "catalytic" heater, which is
something between 200 and 300 watts, I believe.  Wait a sec, that's
easy to check...

Nope, it's more than that.  Motor plus cat heater is around 350 watts. 
So the comparison of the bean heater is 500W to 1400W, more or less.
