Any system that mists water can broadcast bacteria into the air. I remember reading some article about a different disease caused by fungi living in water pipes - problem was cased by inhaling water during showers.

Here is my five cent summary of the information gathered so far:
1) 115 degrees F is an excellent temperature for legionella bacteria to reproduce. So turning your water heater down to this temperature is a really bad idea. A good temperature for a hot water heater is 140 degrees F.
2) 85% of pneumonia cases are caused by legionella bacteria.
3) many solar hot water systems make excellent legionella bacteria incubators. When considering solar hot water designs, make sure your design mitigates legionella issues.
4) To save energy with a hot water heater: Use less hot water; insulate your hot water heater; when your current water heater dies, replace it with a smaller hot water heater; insulate your hot water pipes, so that people using a sink/shower will get hot enough water sooner; turn off your hot water heater when you leave for more than a day.
Any of this less than accurate?
And so what is the temp of the water at the outlet?
Legionella in small domestic water tanks is not a worry. Ships domestic H2O systems and air handlers have vastly different contamination issues.

Crazy question: why not just heat water on the stove and sponge bathe?
While I can't speak for others, I can say that my daughters, darlings though they are, don't appreciate coming downstairs in the morning to see their dad naked in the kitchen touching himself.
Strange, I know, but what can you do? Kids nowadays...
