kilowatt hour (kW·h or kw hr)
the commercial unit of electric energy. One kilowatt hour represents the
amount of energy delivered a rate of 1000 watts over a period of one hour.
Since the watt is 1 joule/sec and there are 3600 seconds in an hour, the

1 watt-hour = 3.412 BTUs. Note the time component.
So, if the element is rated at 1250 watts and is getting the rated voltage and
operates for an hour, it will produce about 4250 BTUs. Actual BTUs produced
will
depend on how much time the element is switched on, which is typically
controlle
