摘要： A vent attachment facilitates attaching a coaxial air intake and exhaust vent of a tankless water heater to a Category I vent, such as B-vent. The vent attachment comprises a first end with a coaxial connector comprising a central exhaust pathway and a circumferential air intake pathway. The vent attachment also comprises a second end with a tubular exhaust vent connector in fluid communication with the central exhaust pathway. The vent attachment further comprises a frame that encloses the central exhaust pathway and comprises a mesh configured to provide fluid communication through the frame with the air intake pathway. Additionally, operation of the tankless water heater is modified to ensure that the exhaust generated is suitable for venting through a Category I vent. The tankless water heater maintains a high fuel consumption rate such that the temperature of hot water produced increases throughout each of a plurality of burner stages.

摘要： System and methods of operating a water heater receiving power from an electrical grid. The water heater includes a heating element, a controller, and a first control circuit. The first control circuit including an energizing terminal and a microprocessor. The method includes connecting an energizing terminal of the first control circuit between a power output terminal of the controller and the heating element, receiving driving power from the controller based on a temperature signal. The method also includes receiving a control signal from the controller based on electrical grid information, and selectively energizing the heating element, by the microprocessor of the first control circuit and through the energizing terminal of the first control circuit based on the control signal.

摘要： A hot water heating device includes a heating chamber with a water inlet for feeding water into the heating chamber and with a water outlet for removing hot water from the heating chamber. The water outlet includes an outlet duct with a suction opening arranged within the heating chamber at a distance to a bottom of the heating chamber and facing a top side opposite of the bottom of the heating chamber. The hot water heating device further includes a heating element arranged within the heating chamber for heating the water within the heating chamber. The water outlet further includes a steam bubble retention device that forms a water intake duct that runs into the suction opening of the water outlet and that prevents steam bubbles to flow through the suction opening of the outlet duct. The steam bubble retention device includes an intake duct with an intake opening and with a muzzle opening that runs into the suction opening of the outlet duct, whereby a cross-sectional area of the intake opening of the intake duct is larger than the cross-sectional area of the suction opening of the outlet duct.

摘要： A water heater control system comprising a temperature sensor, an anode rod, and a controller. The controller is configured to receive a signal indicative of a temperature from the temperature sensor and apply a voltage and/or current to the anode rod. A mounting bracket mates with a spud of a water heater and provides a conduit space for conductors providing connectivity among the controller, temperature sensor, and anode rod. The mounting bracket may provide mechanical support for the anode rod and the temperature sensor. The mounting bracket may comprise a housing mechanically supporting and surrounding the controller.

摘要： A water heater system includes a water tank and a flow-through heating assembly. The water tank contains heated water. The flow-through heating assembly may extend into the water tank and heats water as water is passed through an interior channel of the flow-through heating assembly. In one embodiment, the flow through heater assembly is a thermosiphonic heater having a hollow body and a heating element extending therein such that an annular recess is defined between an interior surface of the hollow body and the external surface of the heating element.

摘要： A water heater including a tank having a wall with an external surface and an internal surface defining an interior, and a circuit board mounted to the external surface of the tank. The circuit board including a thermal path for conducting heat through the circuit board, where the thermal path of the circuit board is thermally coupled to the external surface of the tank. An electronic switch is mounted to the circuit board and electronically coupled to a heating element, where the electronic switch is thermally coupled to the thermal path of the circuit board so that heat generated by the electronic switch is transferred along the thermal path. A temperature sensor is thermally coupled to the circuit board to sense a temperature of the thermal path relating to a temperature of the electronic switch and relating to a temperature of water stored in the tank.
