~Here in Houston, they like to put the hot water tanks in the attic.
Free heat! Rather than heat loss, ambient heat creeps IN to the water!
I have seen electric hot water heaters in Puerto Rico right on the roof, exposed to the elements. [Solar hot water heaters there are a plastic drum that sits on the roof and feeds the water output into the hot water heater].
I was flabbergasted to see a 20 gallon 110v heater (small with slow recovery) for a whole house. But then again the INLET water temperature is very high in that tropical climate, so it's sufficient.
