摘要： A fluid heating system including a burner unit is operated based on feedback control loops. The fluid heating system comprises a burner unit configured to heat a fluid, a sensor configured to sense a characteristic of the appliance, and a controller coupled to the burner unit and the sensor. The controller includes an electronic processor and a memory. The controller is configured to receive a first signal corresponding to the characteristic from the sensor, determine, based on the first signal, a first feedback loop control, control combustion of the burner unit based on the first feedback loop control, determine, based on the first feedback loop control, a second feedback loop control, and control combustion of the burner unit based on the second feedback loop control.

摘要： A water heater system includes a tank having internal capacity no greater than 1 gallon, a water inlet, and a water outlet. A flow of water into the tank through the water inlet and out of the tank through the water outlet is a downstream water flow. An absence of downstream water flow is a standby condition of the water heater. The water heater includes a heating element for heating water in the tank, a first temperature sensor positioned to sense a temperature of the water flowing into the tank, and a second temperature sensor positioned to sense a temperature of the water flowing out of the tank. The water heater further includes a damper upstream of the second temperature sensor to reduce fluctuations in the temperature readings of the second temperature sensor to reduce false detection of downstream water flow.

摘要： A method of operating a water heater receiving electrical power from an electrical grid. The method includes providing a water heater in a locked state. A digital key module may be communicatively coupled (for example, via wired or wireless communication) to the water heater and used to unlock the water heater placing the water heater into an unlocked state. Such unlocking of the water heater must only be done for such water heaters that are enrolled in a utility demand response program.

摘要： Systems and methods for dynamically collecting data from water heating appliances. A water heating system comprises a water heating appliance. The water heating appliance includes a controller having an electronic processor. The controller is configured to receive, in response to the water heating appliance being in a first operating mode, operational data of the water heating appliance at a first sampling rate. The controller is further configured to receive, in response to the water heating appliance being in a second operating mode, operational data of the water heating appliance at a second sampling rate.

摘要： A method of determining an abnormal condition in a water heater. The method including sensing, via a temperature sensor, a plurality of temperatures and filtering, using a first time constant, the plurality of temperatures to produce a first plurality of filtered temperatures. The method further including determining, via a controller, if at least one temperature of the first plurality of filtered temperatures crosses a first temperature threshold, and when at least one temperature of the first plurality of filtered temperatures crosses a second temperature threshold, filtering, using a second time constant, the plurality of temperatures to produce a second plurality of filtered temperatures. The method further including initiating, via the controller, a shutdown procedure when at least one temperature of the second plurality of filtered temperatures, crosses a third temperature threshold.
