A smart water heater system (SWHS) for a domestic water system having a plurality of fixtures has a water tank having a cold water inlet and a heat source configured to heat the cold water. The SWHS may also have a mixing valve to blend cold water with the hot water to produce blended water, wherein the blended water is directed to the domestic water system. The SWHS may have a controller in communication with the mixing valve configured to identify which fixture is being used when the domestic water system is drawing water from the water tank, determine an average water temperature utilized by each fixture, and adjust the mixing valve based on which fixture is identified such that a temperature of the blended water is generally equal to the average water temperature for the identified fixture.
