Is it possible that just running the fan on my furnace is using 1 kW·h per hour? Last night before I went to bed, I checked the meter and let the fan run all night. To my surprise, 8 hours later the meter moved 8 kW·h.
I know we have other appliances that draw some energy when they are off (DVRs, computers, etc.), but I was surprised by this.
If it consumes this much energy just to run the fan on my furnace, I may end that practice altogether.
