How much electricity does the average ceiling fan use?
Question:My wife insists on leaving ceiling fans on in the house day and night to circulate the air. How much do you think it costs for an average sized ceiling fan to run on low 24 hours a day?
Answers:
You will need to research the amperage of your ceiling fan. amps x volts (110) = watts / 1000 = percentage of kilowatt. check your utility bill to find what you pay per kilowatt. if you run your lights take the wattage from each bulb and add to the fan. Example 5 amp x 110 = 550/1000=.55 kilowatt @ $0.24/kilowatt = $ 0.13 per hour.
10 - 100 watt light bulbs left on (kids leaving on lights) = 1000 watts (1 kilowatt) = $0.24 per hour.
About 30W to 50W (without light bulbs). ~
24 hours about 1 KW/hr which depending on where you live could be anywhere from 6 Cents to 15 Cents. Check your electricity bill.
watts x time on in hours x cost per kwh / 1000
SO,
If the fan uses 50 watts
50 x 1 hr. x .06 (local cost per kwh) / 1000 = .003 per hour
3 to 5 amp is ceiling fan amp rage and Min :3amp x120v=360w per hours.
See your electric bill how much you pay for each KW or Mega watt per hours , multiply that times 24 hours plus tax
and other stuff will be your answer.
KW=1000W
