A water heater system includes a water heater and a thermal mixing valve. The water heater includes a tank and a cap that each define interior volumes. The interior volume of the tank includes a heating element is the location where fluid is heated, whereas the cap includes a volume within which the thermal mixing valve may be disposed. The thermal mixing valve pulls cool and warm water from the volume of the tank, and then discharges a mixed stream of fluid at a user desired temperature via an outlet.

A water heating system can include a water heater having a tank, an inlet line, and an outlet line, where the inlet line provides unheated water to the tank, and where the outlet line draws heated water from the tank. The water heating system can also include multiple sensing devices, where each sensing device of the plurality of sensing devices measures a parameter associated with the tank. The water heating system can further include a controller communicably coupled to the plurality of sensing devices, where the controller determines an amount of heated water in the tank based on measurements made by the plurality of sensing devices.

A water heating system can include a water heater having a tank, and a first temperature sensor disposed toward a top end of the tank to measure a first temperature and a second temperature sensor disposed toward a bottom end of the tank to measure a second temperature. The water heating system can further include a controller communicably coupled to the first temperature sensor and the second temperature sensor, where the controller determines an amount of heated water in the tank based on a plurality of algorithms and measurements made by the first and second temperature sensors. The plurality of algorithms solves for at least one calculated temperature for at least one point between a first location of the first temperature sensor and a second location of the second temperature sensor, where the at least one calculated temperature is used to determine the amount of heated water in the tank.

Disclosed herein is a water heating system including a water heater having a tank, and a first temperature sensor disposed toward a top end of the tank to measure a first temperature and a second temperature sensor disposed toward a bottom end of the tank to measure a second temperature.

A method for operating a consumer appliance, as provided herein, may include detecting a preliminary first conversion value from a first sensor input pin electrically connected to an analog-to-digital converter (ADC) and detecting a preliminary second conversion value from a second sensor input pin electrically connected to the ADC in electrical parallel with the first sensor input pin. The method may further include determining a preliminary variation between the preliminary first and second conversion values is less than or equal to a predetermined preliminary threshold. The method may still further include activating a pull-up resistor in electrical communication with the first sensor input pin, identifying a fault state in response based on a conversion value variation following activating the pull-up resistor, and directing the appliance based on the determined fault state.

This disclosure is related to devices, systems, and techniques for controlling a temperature of water contained by a water tank. A controller includes a user interface configured to receive one or more user inputs indicative of a request to set a control parameter of the controller and communication circuitry configured to receive, from a user device, an electronic signal.
