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： An aircraft water supply system supplies water to a water discharge port in an aircraft. A cold water flow path supplies cold water to the water discharge port. A hot water flow path supplies hot water to the water discharge port. A first control valve adjusts the flow rate of cold water flowing through the cold water flow path. A second control valve adjusts the flow rate of hot water flowing through the hot water flow path. A temperature sensor detects the water temperature at any point up to the water discharge port. A flow control unit controls the opening/closing state of the first control valve and the second control valve based on the water temperature detected by the temperature sensor.

摘要： A heating system is configured to optimize the speed and accuracy of the system in achieving various ambient air temperature setpoints, by modulating the heated water supply water setpoint to optimize the slope of the system's response curve. Optimized response curves are automatically determined by analyzing differences between ambient air temperatures over time in response to modulated supply water temperatures as they are reset upward or downward to achieve response times prioritized for improved occupant comfort. The controller of the heating system calculates a temperature slope, and adjusts the supply water setpoint to increase/decrease the speed of ambient temperature rise to achieve a desired slope.

摘要： A water heater appliance includes a tank storing water, a first temperature sensor, a second temperature sensor, and a heat source. A method of operating the water heater appliance includes determining a temperature set point of the water within the tank; obtaining a first temperature of the water within the tank via the first temperature sensor; obtaining a second temperature of the water within the tank via the second temperature sensor; determining a heat depletion level of the water indicating a temperature reduction of the water within the tank based on the temperature set point, the first temperature, and the second temperature; and activating the heat source based on the determined heat depletion level.

摘要： Systems and methods for gas valve adjustment of a water heater are provided. A controller of the water heater may be provided with logic that is configured to automatically adjust the water heater unit to the necessary conditions (for example, blower fan speed, tank temperature, etc.) for an installer to verify an offset setting of a gas valve. The controller may also cause instructions to be presented on a display of the water heater unit. The instructions may guide the installer through the step-by-step process of adjusting the offset setting of the gas valve while simultaneously maintaining optimal operating conditions of the water heater unit.

摘要： Provided are systems and methods for managing a level of heat provided by a processing module and a heating mechanism. In one example, a method includes determining, by a system such as a management control system, that a demand for water from a hot water reservoir is increasing. The hot water reservoir may serve as a heat sink for a processing module and may include a heating mechanism adapted to provide heat to the hot water reservoir separately from the processing module. A determination may be made as to whether the processing module is able to produce enough heat to meet the demand. If the processing module is not able to produce enough heat to meet the demand, the heat output of the heating mechanism may be increased to provide additional heat to the water in the hot water reservoir.
