Claim 0:
1. A hot water delivery system comprising:
a load identification sensor installed in one of a hot water distribution pipe or a cold water distribution pipe of a water supply system, the hot water distribution pipe being configured to deliver hot water to a first load, and the cold water distribution pipe being configured to deliver cold water to the first load;
a mixing valve comprising a first inlet that is coupled to an outlet of a water heater, a second inlet that is coupled to the cold water distribution pipe, and a valve outlet that is coupled to the hot water distribution pipe;
a temperature sensor that is coupled to the hot water distribution pipe at the valve outlet of the mixing valve; and
a controller associated with the water heater and configured to:
determine, based on data received from the load identification sensor, that hot water is being directed to the first load;
determine a first load set point temperature associated with the first load, wherein the first load set point temperature is representative of a maximum temperature of the hot water that is to be delivered to the first load;
cause, based on first feedback from the temperature sensor, the mixing valve to adjust a maximum temperature of the hot water that is delivered from the water heater to the first load from a water heater set point temperature at which the hot water is maintained in the water heater to the first load set point temperature;
determine, while hot water is being directed to the first load, that a second load is switched on and hot water is to be directed to the second load at a second load set point temperature;
determine that the first load set point is different than the second load set point; and
cause, based on second feedback from the temperature sensor, the determination that the second load is switched on, and the determination that the first load set point is different than the second load set point, the mixing valve to modify the maximum temperature of the hot water that is delivered from the water heater to a value between the first load set point temperature and the second load set point temperature.
