Yeah, that was a sneaky one on my part.

One thing I learned from the video was how do water heaters get away with giving higher capacity numbers than they actually have. Well, apparently, kind of like air, hot water also rises and the heater keeps working while in use and it also has secondary heater element it can switch to, so it can follow the cold-hot water separation line.
