I'm not sure what "true power" or power factor corrected" mean, but I'll put up my numbers that are a bit out of line with yours.
My Kill-A-Watt shows a cumulative kilowatt-hour measurement. Today I measured consumption for a 24-hour period (including machine and grinder), and got 1.4 kWh - which means 1400 watt-hours total for the day. If I divide that by the 24-hour day it's drawing 58 watts on average at any given moment, but since it was really on for only 11 hours, it draws about 127 watts on average while it's switched on. I'm guessing you're calculating watts on average for the entire 24 hours, given you're way below my numbers and said the machine is only on a few hours during the week (did you mean a few hours a day?).
I noticed that at idle I'm using 6 watts, then about 1520 when the heating element switches on. The heating element is on 3 seconds out of a thermal cycle of 2 minutes, 49 seconds, so about 2% of the time.
I have a single boiler, insulated.
