I consider my hot water heaters (my home has two) to be a part of my emergency water storage. They each hold 40 gallons so that is 80 gallons of water that is always getting refreshed and rotated. In an emergency, I can shut off the main and drain the tank with the spigot on the side of each one. For that reason, I'd probably never go to a tankless. In my area, when the power goes out, we still have running water. With the hot water tank, it takes awhile for it to cool off so we still have hot /warm water flowing from the tap for another day after the power goes out.
