Abstract

A hot water delivery system includes a water heater, a mixing valve that is coupled to the output of the water heater, and a plurality of loads that are coupled to the output of the mixing valve. A load set point temperature of each load that is representative of a maximum temperature of the hot water that is to be delivered to the respective load is set by a user. Responsive to detecting the occurrence of an event associated with a load of the plurality of loads, a controller of the water heater controls the mixing valve to adjust the temperature of the hot water from the water heater to the load set point temperature associated with the load, provided the load set point temperature of the load is different from a water heater set point temperature at which the water heater maintains the hot water therein.
