Re: Deadly Amoebas Found in Tankless Water Heater said by Bob:said by Jack_in_VA:There is no rational reason to exceed the CDC recommendation of 120 degrees for the the setting. Or maybe there is: said by CDC :
Households with water heater temperatures <=125°F were significantly more likely to harbor nontuberculous mycobacteria (NTM) compared with households with hot water temperatures >=130°F...
NTM disease cases number less than 4,000 per year, and the -vast- majority of those cases are from environmental airborne exposure.
Since, you know, you have to inhale them to contact disease from them. A hotter shower is actually much more dangerous of a risk exposure because of that.
