Yeah, I've seen those heat hump heaters, and the first thing I thought as well was 'monitor top'. Expensive at first but SUPPOSED to save energy.
My philosophy has always been. The water coming in the heater is cold, thus coming out hot. So you could almost call it a COLD-water heater. That's redundant too. I just call it a water heater. My bro-in-law is from Boston (and we all know people from Boston are smarter than everyone else), and he calls it the "Haht Wahta Heetah". So there ya go.
