Boiler Temperature

Pincher

It's basically what's the chance of catching salmonella if you brush your teeth with it, because you are not really supposed to drink from the hot tap any way.

My plumber has always set the cylinder stat at 65 degrees,
and I'm still salmonella free.

The question was boiler temperature, not cylinder temperature.

I have a Glow worm 30SX, which has the outdoor sensor and the Climapro, which overrides the boiler computer altogether. When heating hot water, it runs the boiler output at around 50 degrees, to maximise the condensation effect, but only initially when the cylinder is cold. When the returning water indicates the cylinder is near 50 degrees, the boiler output goes to 80 degrees. The final stage of getting the cylinder to 65 degrees is non-condensing, sadly.

So it doesn't matter what I set the boiler output to, the computer is playing an optimisation game and ignores me.

It would be instructive if the OP clarified which model of Vaillant....otherwise it is all speculation. Btw legionella is the potential hazard.;)

I don't know why, despite loads of coverage and multiple documentaries, I just can't take this word in. It's NOT a proper word!

Anyway, I was brought up in the tropics, where we boil our water before drinking, long before Leggy-Nellie ever killed some old veterans. Death by air-con, who would have thunk it.

I found a dead pigeon in our loft cold water tank, which could have been there for years! Having brushed my teeth for YEARS with water from that tank, my attitude to water has been even more disciplined thence. As far as I'm concerned, I'm killing bacteria, not any specific kind. I suppose you are going to say Leggy-Nellie is the last to die out of all the bacterias, so we might as well focus on that, which is fair enough.
