Low loss header, more efficient with temp sensor?

[c928jon]

I've got a Greenstar 8000 going through a low loss header feeding 3 circuits, two trad rads and one UFH. Will it increase efficiency by instaling a temp sensor on the header and setting the boiler settings accordingly?

I don't understand why you need the header in the first place on a 10:1 modulating boiler that size?
Wont the boiler set header temp anyway?
