How much to run that space heater?
How many watts does your space heater use?
Here’s the correct formula:
A kilowatt hour (kWh) equals 1,000 watt hours, and our residential energy rate is $0.08798/kWh.
• Watts X hrs used = Total watt hours
• Total watt hours divided by 1,000 = Total kWh used
• kWh used X $0.08798 = daily cost
So… If your heater uses 1500 watts and you run it 12 hours each day:
• 1500 watts X 12 hrs/day = 18,000 watt hours
• 18,000 watt hours /1,000 = 18 kWh/day
• 18 kWh X $0.08798= $1.58364 each day running it 12 hours a day
• $1.58364 X 30 (days in a month) = $47.51 per month
