We don't need no stinkin' 'lectrician.frostyra said:Do you work anywhere that there are maintenance electricians? Have one of them check the current draw when the heater is plugged in. If it draws less than 1/2 amp, you might have a problem. Then again, I don't know the rated wattage for the unit -- but it would surprise me if it were more than 100 (maybe 200) watts [or about 1 or 2 amps].
Just buy this cool device Watts Up?. It is a monitoring tools that will show the instantaneous current draw, cumulative kwh (has built in timer) and cost to operate. It's around $90 and one of the cooler Father's day presents I've ever received (ok, I admit that's pretty geeky)
