Second, In Alabama, the power co. (Alabama Power) and the gas co. (Alagasco) have a running feud. The gas co. will give you a gas water heater and install it for free if you currently have an electric water heater. And the electric co will give you an electric water heater and install it for free to replace a gas water heater. So check and see if the same climate exists in your locale.

Legionairs is in every body of natural water and I swim in lakes often, I have yet to contract legionairs.
True your shower vaporizes and spreads it around but if you aren't extremely compromised and sick legionella is in basically everything and few people ever get sick, except again very old, very young and generally people who are very sick.
So I guess thats my way of saying I could care less.
