Avadon Posted November 4, 2009 Share Posted November 4, 2009 (edited) I run my brake drum forge with a hair dryer and I know others throughout the world most likely do the same. Did a little googling because I was worried it might be costly. If these estimates are correct, then for how much work the hair dryer does it's actually well worth the price!!How Much Does It Cost To Run A 1500 W Hair Dryer For 43 Minutes Each Day For One Month (30 Days) At A Cost Of 5 Per KWh? First you convert Watts to Kilowatts, which would equal 1.5 kW, then you find out what portion 43 minutes is of an hour, which would be 43/60, which then equals 0.716666667. Next you multiply 1.5 by 0.716666667 by 30 by .05, which equals 1.61. Here was another answer How much does it cost to run a 1400 W hair dryer 80 minutes each day for one month (30 days) at a cost of 8 ce Well it works out to 40 hours, so it uses 1400w (1.4Kw) then 40 x 1.4KW x 0.08 = $4.48 And another You have an 1800 watt hair dryer used 10 minutes a day at 9 cents per kilowatt hour of energy. cost per year? 1800 watts = 1.8 Kilowatts 10 minutes = 1/6 hour 9 垄 = $0.09 1 year = 365 days 1.8 Kw X 1/6 h X $0.09 = $0.027/day (2.7垄/day) $0.027/d X 365 d =$9.855/year Pretty cheap when you consider how much air it actually pushes and how handy it is. (Edited to add: Remember that these values are also for running the heating coils which I'd imagine has quite a bit more power draw then just running the fan of your hair dryer, thus electricity cost should even be significantly less) Edited November 4, 2009 by Avadon Quote Link to comment Share on other sites More sharing options...
