Block heater pulls 1000 watts. Multiplied times 8 hours, that is is 8000 watt hours per day.
Divide watt hours by 1000 to get the total kilowatt hours (Kwh). In this case, 8000/1000 = 8 Kwh.
Multiply 8 Kwh times the cost per each Kwh that your electric company charges (should be on your bill) to get cost per day. For example, my electric company charges $0.09891 per KwH. Multiplied times 8, that equals $0.79 (rounded off) per 8 hr day.
Some power companies also charge a monthly "customer charge" on top of actual power consumed. To figure your fair share of the bill, you need to divide your monthly Kwh by the total Kwh on the bill, then multiply the monthly customer charge by that percentage. For example, assume your monthly Kwh consumption is 160 (8 kwh per day times 20 days), the monthly customer charge is $10.00, and the total Kwh on the monthly bill is 1650. 160 divided by 1650 = 0.0969697, times 10.00 = $0.97 (rounded off). So, your share of the bill would be $15.82 + $0.97 = $16.79.
