TW> That statement got lost in this old Brain. cost of rinning an electric   
   TW> motor for an air compressor is a function of the horsepower of the   
   TW> motor. There is very little difference is electrical KW usage of runing

   TW> Now of course the 110 motor consumes twice the amps but that is cancled

   TW> The Kilowatt Metered usage onthe power company meter is the same

   Interesting..     
      
   When I had my hot tub, if I would have connected it 220v, it would have heated   
   up way quicker.  If that was the case, then it would have been less expensive   
   to go 220 - even if it was apples to apples since it would run less time.
