If only this were true. Chiller, maybe 5 amps? Big pumps for circulation and skimmer, 5 amps easy when you add 'em up. I never ran a chiller, but I can tell you my AC cost really went up when I had my 110, and that's a pretty small tank, relatively speaking. I had to keep the room at 77 just to keep the tank at 84 in the summer.
