Has anyone actualy got legionares from a HW tank. Doesnt it need open
air to establish and breed.

yes it was in the sealed and pressurized water system in that hotel.
it grows in warm water.

they used repeated pure bleach to kill the bacteria

What hotel, the only hotel I heard of it was in stagnant water from AC
chillers or other AC equipment. I can understand non chlorinated, warm
pooled water growing anything, but chlorinated, sealed, moving,
pressurised systems, no I have not heard that as fact.

the old heater sounds like a ideal growing medium

Q. What water conditions are best for growth of the organism?

A. Warm, stagnant water provides ideal conditions for growth. At
temperatures between 20�C-50�C (68�-122�F) the organism can multiply.
Temperatures of 32�C-40�C (90�-105�F) are ideal for growth. Rust
(iron), scale, and the presence of other microorganisms can also
promote the growth of LDB.

OK an interesting point it was in the hot and Cold water of a
hospital, no hospital will heat under the 120f code, for a hospital
code is probably much higher, but explain the cold water contamination
and the fact they heat water very hot.

cold water in such a large building may get warm easy, people are
immune supressed, hospitals have labrinth of pipes, some water sources
may get litte use with long sit times for cold water to get warm

I'm wondering if the key word there might be "stagnant?" I don't know
how long water would have to be stagnant for????? Days? A week? A
few hours? I would think in a one family house that water would be
moving through the hot water system at least daily. Do you think you
would get anywhere close to 100% turnover in a hot water tank at least
every couple days depending on usage? In my tanks (tempering tank
included) the cold water inlet has a pipe extending down into the tank
nearly to the bottom so the cold water entering must rise upward to
exit the tank in the hot water outlet.

I just finished piping up my tempering tank yesterday evening. I
figured it would take at least overnight or longer to see a change as
our cold water is probably 50 degrees F and it took 52+ gallons to
fill. This morning when running hot water for the clothes washer, the
copper pipe with the tempered water going to the new water heater was
just cool to the touch (guessing about 80 degrees F water). The pipe
with the cold water that was entering the tempering tank felt icy
cold. I took a reading on our electrical service meter this morning
so I will be checking it for the next week or so.

I see them listed, but no details for some of them. The original
Legionnaires disease was from a Philadelphia hotel and it was the cooling
tower that was infected, not the water system.

One case mentioned in your list had it in both hot and cold water so the
temperature did not matter in that case. Another was a hot tub. Another
was a fountain. Seems to be may potential sources but cooling towers are
one of the biggest. From what I've seen, there is no sure way to eliminate
it, but much potential to cause spreading.

Another update: Looks like it just might be a winner....
After taking a couple more days of meter readings with normal hot
water usage and other electrical usages remaining fairly constant, I
figure we are using about 7 - 8 kwhs less per day. Tempered water
going to the new water heater is fairly close to 100 degrees F. I
think having the tempering tank near the wood stove with a recirc loop
actually piped over the wood stove makes the difference. I'm
considering one more piping change to the recirc loop which might
capture even more heat from the wood stove....

Happy New Year!
