How much energy will continuously running a furnace fan use?
So for every hour the motor runs, it will use 0.943 kilowatts of power. Total power/day = 0.598kWh * 24h Total power/day = 14.352kWh Total power/month = 14.352Kwh * 30 Total power/month = 430.56kWh Finally, if you multiply this number by the amount you pay per kilowatt hour. You'll see just about how much it costs to run the motor constantly.
