My water is set to 50 because my shower only goes that high, anything more would be a waste tbh the taps are mine at 50.
Did you gas man toggle your boiler to be in comfort mode so hot water is always readily available instead of the boiler manually calling for hot water when you turn the tap on? Mine is off. It adds to the bill considerably when on.
There's no efficiency while your boiler is set too high. The whole point of it is to steam inside, recycle the heat your boiler produces. Your boiler must be extracting a lot of heat through the exhaust pipe.

I've got a modern condensing boiler but it's also a system boiler because I kept my tank so I'm not really sure if the boiler temp just affects radiator temp because the tank has a dial on it for temperature under a screwed panel, I guess I'll find out in a few days.
Edit- I remember when I bought the house 28yrs ago I had to turn up the tank temperature because the hot water never got hot enough so I guess I have answered my own question.
