Benefits of technology
The system provides immediate and consistent temperature control, reducing the time for water to reach the set temperature during draw events and optimizing space usage by allowing smaller tank sizes while maintaining large volumes of usable heated water.
Problems solved by technology
Thus, the volume of heated water available at the predetermined temperature is generally limited to the volume of the tank.
However, large water heater appliances with large tanks occupy large amount of space within a residence or business.
In certain buildings, space is limited and / or expensive.
Thus, utilizing large water heater appliances can be impractical and / or prohibitively expensive despite needing large volumes of heated water.
For example, adjusting the ratio of cold water to hot water with the mixing valve takes time.

A water heater appliance includes an electronic mixing valve configured for adjusting a ratio of cold water from a cold water inlet conduit to hot water from a hot water outlet conduit at a mixed water outlet of the electronic mixing valve. A cold water bypass conduit extends between the cold water inlet conduit and the mixed water outlet conduit. A cold water bypass valve is on the cold water bypass conduit. A controller is configured to close the cold water bypass valve when a temperature measurement from a mixed water temperature sensor is less than a threshold temperature.
Description
FIELD OF THE INVENTION[0001]The present subject matter relates generally to heat pump water heaters and mixing valves for water heaters.BACKGROUND OF THE INVENTION[0002]Certain water heater appliances include a tank therein. Heating elements, such as gas burners, electric resistance elements, or sealed systems, heat water within the tank during operation of such water heater appliances. In particular, the heating elements generally heat water within the tank to a predetermined temperature. The predetermined temperature is generally selected such that heated water within the tank is suitable for showering, washing hands, etc.[0003]During operation, relatively cool water flows into the tank, and the heating elements operate to heat such water to the predetermined temperature. Thus, the volume of heated water available at the predetermined temperature is generally limited to the volume of the tank. According, water heater appliances are sold in various sizes to permit consumers to sele...
