I agree that the proper term in almost all situations is just water heater. But to say there is no such thing as a hot water heater is incorrect. We used to need hot (100.4F) water flowing all day for our film processors. The only practical way to do that was three large water heaters run in series. The first one would warm the water, the second would get it hotter and the third would finally get it hot enough to blend with cold water to get a steady 100F. We had enough valves that we could bypass any one heater for a short time for replacement without stopping production. That was only possible if it was summer time. In the winter we had to have all three running.
And as my little know fact for the thread:
Kodak has stopped production of aerial film. Agfa makes all the world's areial film now. Even Japan, China & Russia just buy Agfa aerial film. One roll of film is 9 & 7/16th inch wide and 443 feet long and costs over $2,800.
