Is this not a good way to use a water heater, assuming it stores enough hot water to meet all demands?

The best way to set the thermostat on a 40 gallon water heater would be to leave it at 10 degrees Fahrenheit above body temperature until laundry day and then temporarily raise it for the laundry to "instant scalding" temperature (155 degree Fahrenheit). When laundry is done turn it back to 110 Fahrenheit.
