    摘要: A water heater system includes a controller configured to integrate control of both recovery and recirculation operations of a recovery pump and a recirculation pump. As such, a separate device, installation location, and power source (e.g., available outlet) is not needed with the controller. Because a single controller is configured to control both recovery and recirculation operations, additional control functions are available. The controller may be in communication with an internal controller of the water heater and configured to receive an error notification upon abnormal operation of the water heater. The controller can stop recovery and recirculation operations in response to an error notification, unlike with traditional water heating systems which may otherwise continue to function. The recovery and recirculation operations are based on a setpoint temperature of the water heater such that changes made to the setpoint temperature will automatically adjust in the recovery and recirculation operations.

    摘要: A building management system (BMS) gateway comprises a BMS router and a water heater hub configured to be communicatively coupled to a plurality of water heaters. The BMS router facilitates communication of status and control data between a BMS and the water heaters connected to the water heater hub. Connecting multiple water heaters to a single BMS gateway provides simplified installation and networking requirements. For installations with more water heaters than are able to be coupled to the water heater hub, additional BMS gateways may be installed. Local controls for water heaters managed by the BMS are typically disabled or overwritten by the BMS to prevent changes to settings. A local BMS user interface (UI) is configured to connect with the BMS gateway(s) and facilitate secure access, display, and/or adjustment of water heater status and control data for the plurality of water heaters connected to the BMS gateway(s).

    摘要: Various implementations include a hot water heating system having a spine and two or more water heating units. The spine includes a top surface defining one or more top openings, two or more coupling areas, and cold water, hot water, and fuel manifolds. One or more top openings provide access to a cold water manifold inlet, a hot water manifold outlet, and a fuel manifold inlet. At least one of the coupling areas is located above another coupling area when the spine is oriented with the top surface facing upwardly. The water heating units are coupled to coupling areas such that a cold water inlet of the unit is fluidically coupled to the cold water manifold outlet, a hot water outlet of the unit is fluidically coupled to the hot water manifold inlet, and a fuel inlet of the unit is fluidically coupled to the fuel manifold outlet.

    摘要: A hybrid water heater incudes a storage tank, a first temperature sensor, a tankless heater fluidly coupled to the storage tank, and a controller configured to determine a target output temperature range for the tankless heater based on a temperature setpoint, measure a temperature of hot water stored in an upper portion of the storage tank using the first temperature sensor, determine whether the measured temperature of the hot water is less than a first minimum temperature setpoint, generate an adjusted target output temperature range for the tankless heater based on a determination that the measured temperature is less than the first minimum temperature by increasing a value of both the lower threshold and the upper threshold, and control the tankless heater to produce the heated water according to the adjusted target output temperature range.
