Electric water heater crud build up verus temperature
Ashton Crusher wrote:
I've noticed that setting my electric water heater on "really hot" seems to cause a lot of crud build up. On "normal" or a little lower it doesn't seem to build up nearly as much crud. This seems backwards to me. Hotter water should be able to hold more dissolved stuff so why does more of the dissolved minerals seem to come out at higher temps?? Hmmm, Do you ever flush the tank? |

But with the hot setting I flushed it when it was about 18 months old and it was jammed with crud. Did it again about a year later when the lower element burned out and it was full of crud up to the element. Set the temp lower and haven't flushed it since (at least 4 years) and since the element has not burned out again I'm assuming it's not buried in crud this time. |

What is set temp. on the thermostat? |

What is set temp. on the thermostat? Yes, we have pretty darn hard water. Setting is just below "normal", probably about 130 degrees. |

Yes, we have pretty darn hard water. �Setting is just below "normal", probably about 130 degrees.- Hide quoted text - - Show quoted text - 130 is plenty hot for all uses provided the tank is large enough. lower temp ON gas tanks equals less thermal stress and longer tank life |
