It is generally the case that you will use less gas with the boiler temperature turned up.
This is because oil/gas boilers are at their most efficient running at a higher temperature (the implication of this is that a greater proprtion of heat generated disappears up the flue at a lower temperature).
Bearing in mind that the majority of gas used in the winter services the demand for the CH (not domestic hot water) running the boiler temperature at the higher figure will result in less boiler cycling (means when the boiler keeps going on and off in short intervals).
That is the logic.
