Here is one of the papers I mentioned on the study of water temperature and electric water heaters in particular and the risk of Legionnaires disease.

Maybe more to the point than studies and Safe Kids Canada media campaigns, is what the codes say. In Australia, storage heaters have a minimum thermostat setting at 60, and tempering valves at 45 are required in all new construction. That has been the law for years and, somewhat ironically, I understand a lot of the research on which it is based came from Canada.
