It’s a heater to make hot water. As opposed to a space heater, which is a heater used to heat a space and a food heater that is a heater used to heat food to serving temps and a floor heater which is a heater to warm up a floor.
But a water heater is going to produce hot water, right? That’s what it does. It’s redundant to call it a hot water heater, unless you have multiple water heaters for different temperatures, then you’d need to specify, like the lukewarm water heater. I’ll note that we don’t call them hot food heaters, warm space heaters, or warm floor heaters, because we know that’s going to be the result.
