Turning the thermostat to 26 will make no difference to how much heat the
boiler will put out and thus no difference to how long it takes to heat the
room. It only affects at what degree of warmthness the CH turns off.

The only ways to get the room warmer earlier a
1. Turn the heating on earlier
2. Increase the heat output of the system by adding radiators if there is
spare boiler capacity, or increasing the size of the boiler

Assuming the boiler thermostat isn't already up full of course, and the
OP did say "increase the heater temperature" - which suggests it isn't
Albeit the effect of flow temp on warm up time depends on the Kw output
of the boiler, amount of water and number of rads in the system...
