How much hot water do you use?

Water heaters are multiplying grounds for nasty things (which is why
one should never ingest hot water).

If you use only a small amount, try draining the water heater to
fill it with fresh. Find some way to inject a spoonfull of bleach
into the newly-filled tank.

And whatever you do, DO NOT run it as low as 145F. A water heater
needs to be HOT to be safe, particularly on well water
(non-chlorinated)

Good point, but if you don't ingest any of the water from the heater, you
should be (mostly) okay with a lower temperature. Meanwhile, a lower
temperature will reduce your fuel bill and, more importantly, save the earth
from natural resource depletion, global warming, and other assorted ills.

It's for the children.
