Is there anyone out there who has installed a Waterfurnace Series 7 with the "home energy" system? Looking for someone to compare runtime and KW/hrs with. As you can see in the attachment for the month of November the total KW is 0.4. I am told this is a monthly average for November. If that is true then; 0.4KW X 30 days = 12 KW/hrs. Now, 12 KW/hrs X .13cents/KWH = $1.56 cents for 423 hours of runtime. I am having a really hard time believing that.
