Can solar hot water systems be prone to Legionnaires disease?


I was discussing with my Father-in-law his new car and he mentioned that he’d read somewhere that 1 in 5 cases of legionnaires disease is caused by stagnant water in a cars windscreen washer bottle.

And it makes perfect sense really…. warm conditions, a bottle always topped up so any dregs infected mix with the fresh water.

It’s then squirted onto the windscreen and the vapour in the air is sucked through the air fan and blown into the car’s sealed environment.

Funny that we were discussing that only the other day when I came across a blog post regarding legionella and bacterial infections in solar hot water systems.

More on that in tomorrow’s post.

TTFN.
