Does turning up water heater make hot water last longer?

When you raise the water heater temperature, the tempering valve will automatically reduce the volume of hot water in the mix to prevent scalding. Thus, the rate of consumption DOES depend on temperature. The lowered rate WILL make the hot water in the heater “last longer”.

Why does my hot water run out so fast?

Sediment is formed from loose minerals that are found naturally in water. When they settle at the bottom of the tank, it causes your tank to run out of hot water quickly.
