Hi All,
I was talking to a customer today who works for Rentokil, his job involves him going round hospitals and schools testing water tanks for Legionnaires' disease.
I asked him about heating water in my tank as per immersion heater, and he doesn't advise it.
He says the bacteria breeds in water between 20 and 45 degrees and it's optimum at 38 degrees. He also says that Wfp disperses water the same as aerosol effect which makes the bacteria airborne and is dangerous.
He says either use below 20 degrees or above 50 out of the brush and drain the tank each day.

Has he ever cleaned windows for a living?

[Dave Willis]

Yep, it's well known on this forum. Trouble is everyone has decided to turn a blind eye whilst the immersion tank fever takes hold

No I don't think he has cleaned windows, this is advice from someone who tests bacteria in water on a daily basis and sends people in to clean tanks.
It's up to you if you take advice or not!! Only trying to help.

In stagnent water! Water thats not moving. You replace it every day, its really NOT a concern in my eyes.

did you explain to him the water is in the tank for a very short period of time and is constantly being changed with fresh water.

[jr windows]

Yes, I said I use nearly all my tank every day, the bacteria can breed in hours apparently. Like I said in my last post it's advice, only trying to help. Wouldn't want to read on here about anyone contracting Legionnaires' disease!!

fair enough thanks

what about fish tanks have they got it, the water is never changed in them is it

[windiewasher]

lol love these posts.
its pure water 38 degrees is boiling point so kills any bacteria!
your washing windows not drinking it.
ro systems are for drinking water!
isnt kettles a water tank.
plastic drinking bottle of water a tank?how long till you drink it?months!

boiling point is 100 c

your washing windows not drinking it.

That is exactly the point.  Breathing in the mist is what matters, not drinking it.

Do fish tanks have an airbourne spray? I think the problem is when the bacteria leaves the tank and gets sprayed, then humans breathe the air.
I have bought an immersion but don't think I will use it.

[windiewasher]

right you mean a airbourne spray like a fountain,or the sea or a sprinkler or a hose pipe pressure washer?
were all doomed,time to give up now!
if you go swimming please make sure noboddy splashes water or jumps in!

you are talking rubbish, read what he put, How the bacteria forms, and at what temps. How it is dispersed. Its is a very real threat.
Matt on his forum has discussed it with a legionnaires expert, He was very worried about the use of immersion heaters this way.
Its ok if you heat as you use, but when you heat and store then there lies the risk. He heats his water to 16 degrees which is cold enough to stop bacteria forming and warm enough to prevent freezing all day (his words,not tried it myself).

[jr windows]

If people read my post properly it states Below 20 degrees or over 50.
I was going to heat my water to aprox 40 degrees so by the time it hits the window it's at 30 degrees. I am concerned about spraying 50 degrees or above on to glass at this time of year.
I shall go back to this customer and tell him he's talking out of his backside.

[clearlyclean]

I wouldn't use water above 20oC in fear the glass shatters with temperature shock.Did this expert give any advise on how often we should disinfect our tanks and I would say these bacteria would have to be present after passing through an R/O and DI unit to breed and they are in a closed unit till it comes out the brush unlike cooling towers where must cases have been.

I shall go back to this customer and tell him he's talking out of his backside.

while your there tell him to watch out for the spray from the sea, and the boiling 38 degrees water
