摘要： A water heater including a cabinet having an inlet, an outlet, and a flow path disposed between the inlet and the outlet and having a plurality of upper and lower junctions to redirect the flow path. Each lower junction includes a drain port. A flow rate sensor measures the flow rate of the fluid through the flow path, an inlet temperature sensor measures an inlet temperature, an and outlet temperature sensor measures the outlet temperature. Heating elements are disposed along the flow path between the inlet and outlet temperature sensors, and intermediate temperature sensors are disposed adjacent respective heating elements to measure an intermediate temperature within the flow path. A controller operates the heating elements to heat a fluid within the flow path to a predetermined set point temperature based on the measurements of the flow rate sensor and temperature sensors.

摘要： A thermostat including bi-metal element configured to be activated at a maximum dial setpoint temperature manually set on the thermostat and a switch coupled to the bi-metal element and configured to open upon activation of the bi-metal element. The thermostat also includes a temperature sensor positioned to sense temperature, a thermostat heating element positioned to heat the bi-metal element to the maximum dial setpoint temperature, and a controller coupled to the temperature sensor and the thermostat heating element and storing a desired controller setpoint temperature. In response to determining that the desired controller setpoint temperature is sensed, the controller controls the thermostat heating element to heat the bi-metal element to the maximum dial setpoint temperature, thereby activating the bi-metal element and opening the switch.

摘要： Disclosed is a water heater that has a water storage tank, a first pass flue tube extending from a top of the water storage tank to a bottom of the water storage tank, a down-fired burner assembly positioned to direct combustion gases into the first pass flue tube, a plurality of second pass flue tubes extending from the bottom of the water storage tank to a top of the water storage tank, and an expansion chamber positioned below the bottom of the water storage tank. The expansion chamber receives the combustion gases from the first pass flue tube and delivers the combustion gases to the second pass flue tubes. The water heater operates with a non-positive vent static pressure and with a vent gas temperature that avoids or reduces excessive condensate production in an exhaust vent connected to receive combustion gases from the water heater.

摘要： A water heater system, including a water storage tank, an electrical heating element, a power switch, and a controller. The controller is configured to store a number of heating cycles completed to heat water in the tank. When electric power is applied to the water heater system, the controller controls the power switch to turn OFF power to the electrical heating element in response to the number of heating cycles being less than a threshold number of heating cycles, and controls a user output interface to output the indicator indicating that the controller is inhibiting operation of the electrical heating element, and control the power switch to turn ON power to the electrical heating element in response to receiving user input through a user input interface requesting power to be applied to the electrical heating element, and a sensed temperature of the tank being less than a setpoint temperature.
