Referring to the graph, the baseline energy use with most everything in the house tuned off is somewhere between 300 to 400 watts. Occasionally, the refrigerator compressor will come on adding about 200 watts to this for ten minutes or so. In the graph you can spot the ‘surge’ as the three phase motor kicked in. This unit uses sensor to step down the heat as it senses that the humidity on the dryer goes down.
I began the run at 11:17 AM and it finished at 11:43 for a total of 26 minutes. As you can see the unit used about 3 kilowatts of power over this time which still only amounts to about 30 cents worth of electrical power.
