Abstract: Systems and methods are provided for adaptive flow across multiple water heaters. The system may include a plurality of water heaters provided in a cascaded arrangement, with each of the water heaters including a valve. The valves may be, for example, motorized isolation valves that may be automatically closed and/or opened by one or more controllers associated with the water heaters. This may allow for the system to automatically regulate the flow rate through each of the water heaters to provide for optimal usage of the cascaded water heaters. For example, if it is determined by the one or more controllers (based on sensor data from the water heaters) that a flow rate has decreased below a threshold value for a giving water heater firing rate, one or more valves may be closed such that fewer water heaters are used and the flow rate is increased.

Abstract: The disclosed technology includes systems and methods for operating a pool water heating system. The pool water heating system can include a heat pump, a supplemental heat source, a water temperature sensor, and a controller. The controller can be configured to receive water temperature data and, in response to determining that the temperature of the water is less than a threshold temperature, output a control signal to activate the heat pump. The controller can further determine an expected heating time that can be indicative of an amount of time required for the temperature of the water to be greater than or equal to the threshold temperature. The controller can also generate a heating schedule based at least in part on the expected heat time and a predetermined time of use. The heating schedule can be indicative of a heat pump operation time and a supplemental heat source operation time.

Abstract: Systems and methods for detecting a power imbalance in a three-phase electric fluid heater and selectively deactivating heating elements to maintain functionality in a reduced power state are provided. Methods include detecting a faulty or malfunctioning heating element in a three-phase electrical connection, determining counterpart heating elements in non-faulty legs of the three-phase electrical connection, deactivating select heating elements in each non-faulty leg of the three-phase electrical connection, and maintaining output of the electrical heater at a reduced power setting. Similarly, heating elements in each leg may be selectively deactivated to reduce power consumption in a fluid heater system in response to reduced demand or grid requirements.

Abstract: Disclosed are systems and methods for automated hybrid pool heating unit configurations. An example method may include determining, by a processor, a first input parameter associated with an operation of a pool heating system comprising a first pool heating unit and a second pool heating unit, wherein the first pool heating unit is a first type of pool heating unit and the second pool heating unit is a second type of pool heating unit. The example method may also include sending, using the processor, based on receiving the first input parameter, a first signal to enable the first pool heating unit to heat a first pool. The example method may also include determining, by the processor, a second input parameter. The example method may also include sending, using the processor, based on receiving the second input parameter, a second signal to enable the second pool heating unit to heat the first pool.

Abstract: The present disclosure addresses systems, media, and methods of configuring a heating system comprising a plurality of combustion-type heating devices fluidly coupled to a vent system. Configuring the heating system includes receiving operating pressure data from one or more pressure sensors in a flue of one of combustion-type heating devices and the vent system. The operating pressure data from the one or more pressure sensors is indicative of a pressure at a corresponding location in the vent system. Configuring the heating system further includes comparing the operating pressure data to stored operational pressure data indicative of operational pressure ranges indicative of permissible operating parameters associated with preventing backflow of flue gases into the one of combustion-type heating devices and outputting instructions for a damper to at least partially open or at least partially close based at least in part on the operating pressure data and the stored operational pressure data.

Abstract: The disclosed technology includes a controller configured to control an output of one or more boilers to reduce temperature overshoot of the boiler system. The controller can receive temperature data, a threshold temperature value, and a maximum temperature value, and determine whether the temperature of the water in the boiler system is greater than or equal to a threshold temperature. The controller can also determine a number of operating boilers that were operating when the threshold temperature was reached and determine a temperature increment value based on the threshold temperature, the maximum temperature, and the number of operating boilers. The controller can output a control signal to a boiler to reduce an output of the boiler based on the temperature increment value and the temperature data to reduce overshoot of the boiler system.
