Ever wonder why we call it a "hot water" heater when its function is to heat "cold water"?
I have. :)
Obviously because it's function in heating the cold water (which soon ceases to be cold water, becoming lukewarm, warm, and finally hot) is to make hot water. It distinguishes it from other heaters, I guess.
I have an oil-fired hot air furnace in my house. It isn't a cold air furnace; and if for some reason it becomes one, I need to phone a repairman pronto or suffer the consequences. I guess it doesn't bug me in the least that a hot water heater is similarly named.
