Valid point, Jerry.
Had a call last year about this time from a medical billing company. They want(ed) to be able to have a "little" space heater in each one of the cubicles.
After trying in vain to explain to them the scope of what they were asking, I asked why they couldn't just turn the thermostat up a few notches?
No, they'd rather run 24 1500W heaters all winter long...
Lessee: 1500W x 24 units x 12 hours per day x 20 days per month / 1000 to convert to KWh x $0.08 per KWh...
*)that's uh, $691.20 per month in Power not counting the sub-panel, receptacles, and all the other work involved... (If I got the math right...)
Oops! I Did it again!!
