Suppose I was to tell you there exists a tankless water heater you could install on the hardest of hard water that would never, ever have to be descaled and that its heat exchanger’s water pathways would look almost as clean as the day it was born. You’d think I’d gone off my meds — right?
At every AHR trade show, I look for the one product that is a true game-changer. One that stops me dead in my tracks, grabs my attention and doesn’t let go. There were literally hundreds of contenders, as there are at every AHR show, but the new A. O. Smith X3 tankless technology is, without question, a stunning achievement that once and for all eliminates the No. 1 enemy of tankless water heaters — scale buildup.
