“I was amazed to find that my furnace circuit accounted for 40% of my electricity usage. It turns out, I had inadvertently turned on the whole-house humidifier which is attached to the furnace, and it was sucking up energy like crazy. Now that the problem has been diagnosed and fixed, I am probably going to knock $70 off my bill for next month! Without the eMonitor, who knows how long it would have taken me to diagnose and correct the problem.”
