Boiler temps

[Fitfunfab]

Hi
I live in a house that was built in 1996/1997
I have the boiler serviced every year

i have an airing cupboard with what there is a tank/cylinder that’s is set to 60 degrees.

So I looked at the temp settings on my boiler and the water setting was less than 60 it was over 50 though so I turned it to 60 as I guess that’s what it needs to be? Minimum for safety? But now the water seems really too hot. I am reading conflicting information online And that some boilers now can be set lower in really confused ?
I think there may be something in the loft too as something leaked once but that may have something to do with the immersion heater that I never use I don’t know ??? I have a valiant 415 ecotec plus. Surely a boiler would have a sign or warning to say don’t set less than 60? The airing cupboard doesn’t have a sign either ?

Anyone ?

For economy reasons you want to set the hot water temperature to be hot enough to use, but not so hot that you have to add cold water to it. (as that's just madness!)

Thanks the gasman come to do the annual boiler check today and he said on my vallaint 415 ecotec boiler the water setting doesn’t do anything? However I’ve put that on 55

he said the radiator seating needs to be above 60. as the tank in my airing cupboard is 60
