Abstract
Hot water heater systems and methods for monitoring electronic mixing valves of hot water heater systems are provided. An electronic mixing valve provides a flow of water in a mixed output line. A method includes determining whether an output flow event is occurring, determining a first temperature value for water in the mixed output line when the output flow event is occurring, comparing the first temperature value to a setpoint temperature value to obtain a first temperature error value when the output flow event is occurring, and generating a failure signal when the first temperature error value is outside of a predetermined error range and the output flow event is occurring.
