An instant inline water heater can certainly add to the heat

your fill time.

An instant online heater will have no effect until the tank is empty and
then won't have enough power to heat any flow of water unless 10kW or more.

Instant heating can run while the cylinder fills the bath. It gets you 2 hot supplies at once, one stored & one via the cold tap. Result: more hot water available. But it's moot, just turn the temp up a little.
