摘要： A water heater system includes a gas burner configured to selectively produce flue gases, and a heat exchanger for heating water in the water heater system. The water heater system is operable in a heating mode, and a standby mode. An exhaust assembly is in communication with the heat exchanger, and includes a condensate collector configured to receive the flue gases and condensate. A first temperature sensor is positioned to sense a temperature of the condensate within the condensate collector. The first temperature sensor is configured to detect a rate of temperature change of the condensate. A controller is configured to determine a leakage when the rate of temperature change adjusts from a first state to a second state when the water heater system is in the standby mode after the water heater system was in the heating mode.

摘要： A water heater includes an inner water tube coil and an outer water tube coil separated by a drum baffle. The inner and outer coils extend above a top edge of the drum baffle by at least a full turn of each coil. A flue gas bypass path is defined between a top edge of the drum baffle and a top insulation layer above the inner and outer coils. Flue gases flow radially though the inner coil, up along the drum baffle, through the flue gas bypass path, and downwardly over the outer coil to heat water flowing through the inner and outer coils. The water flows into the outer coil at the bottom of the coil, winds upwardly through the outer coil in countercurrent flow with respect to the flue gases, then down through the inner coil.

摘要： A method of operating a water heater, the method including determining a predicted variation of a hot water consumption rate variable over a future time period and calculating a total required operating time of the water heater over that time period. The method further includes determining multiple possible operating profiles of the water heater that provide the total required operating time, and calculating a minimum hot water reserve for each profile. One of the profiles is selected based at least partially on that profile providing a minimum hot water reserve that is not less than a predetermined desired reserve capacity and the water heater is operated over the time period using that profile. The selected profile may be the profile that is calculated to have the lowest operational cost.

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： The present disclosure discloses a proportional valve body, a proportional valve and a manufacturing method for a proportional valve body. The proportional valve body comprises a body extending in an axial direction, the body being provided with a first cavity and a second cavity penetrating therethrough in the axial direction and isolated from each other; the body being further provided with a first through hole penetrating through an outer wall of the body, the first hole being communicated with the first cavity and isolated from the second cavity. In the present disclosure, the first cavity and the second cavity of the proportional valve body penetrate through the body in the axial direction, thus the general structure of the proportional valve body can be obtained by means of extrusion molding. Extrusion molding has the advantages of easy operation, high productivity, and high utilization ratio of raw materials. And the proportional valve body obtained by means of extrusion molding has favorable structural and mechanical properties.

摘要： A tankless water heater includes a scale control module (SCM). The SCM is mounted inside or outside of a cabinet which encloses a heat exchanger and source of heat of the water heater. The SCM may include a connector and a cartridge removably attaching to the connector or may only include a cartridge permanently affixed to the tankless water heater. The tankless water heater includes a continuous water pathway inside the cabinet to supply water to all components of the tankless water heater, including the SCM. The tankless water heater receives supply water at its inlet, treats the supply water in the SCM to generate treated water having reduced scale-forming characteristics compared to the supply water, and heats the treated water in the heat exchanger to generate heated treated water.

摘要： An atmospheric gas water heater includes a burner assembly. The burner assembly includes a burner having a body, and a screen member coupled to the body. A conduit is fluidly connected to the body. The conduit has an open end configured to receive gas and air. The flow of gas and air from the open end through the conduit to the body and past the screen member is defined as a downstream direction. The screen member defines a zone of combustion. The gas and the air is 100% premixed together upstream of the zone of combustion. The body of the burner has a first segment extending between a first end and a second end, and second and third segments extending from the first segment. The second segment and the third segment extend parallel to and spaced apart from each other to form a U-shape.
