Ive noticed units that are 115 v. at high EER's (energy efficiency ratio) such as 10.5 but they draw higher amps . And ive noticed 230 v. units of the same capacity at a lower EER such as 9.5 ... yet they draw as much as half the running amps that comparable 115 v. units do. Its my understanding that its amps that spin the electric meter, so, since i have both 115 and 230 volts available as a power source, which is going to use the least electricity in the example above ? thanks.
