What is the best temperature to keep the boiler on? What do you keep it
on?The maximum 82 degree or 60-65?
High temp = more gas but lees time to heat the house.
So how do you find it best to set?

I have the heating on near max ~70 (75 max)
I have the tap water on ~50 since it is very hard water and it keeps the
scale down.
Combi - I get to choose both.

as will any other system with a hot water
tank that has a stat on it.

You turn the temp up enough to get the heat output you need. lower is more
efficient at fuel use, higher is more efficient at heating the house!

Nope. He has full independent control of CH & DHW. With a cylinder stat the
CH rad temperatures can't be less than what the DHW requires. Unless you
put in a diverter system (easy to do or convert from a non-diverter system)
with a pipe stat on the boiler flow or return for CH rad temp, controlling
the boilers temp. Then the boiler can be left on full meaning a fast warm up
fro CH.
