Abstract: A water heating system is disclosed. The water heating system may include a sensor configured to detect an anomaly in the water heating system, and a timer configured to detect hot water usage time duration. The water heating system may further include a controller configured to obtain inputs from the sensor and the hot water usage time duration from the timer. The controller may be further configured to determine that a predetermined condition is met based on the inputs or the hot water usage time duration. Responsive to a determination that the predetermined condition is met, the controller may be configured to modify a water flow or an output water temperature for a predefined time duration to provide an alert signal to a user.

Abstract: A system for use with a fuel-burning water heater and a ventilation conduit is disclosed. The fuel-burning water heater is configured to burn fuel and generate gaseous exhaust and condensate from the burning of the fuel. The ventilation conduit is configured to remove the gaseous exhaust from the fuel-burning water heater. The system includes an input port configured to receive the gaseous exhaust and the condensate, a neutralizing material holder configured to house a condensate neutralizing material therein and to receive the condensate from the input port, a gas output port configured to provide the gaseous exhaust to the ventilation conduit, and a liquid output port configured to output condensate from the neutralizing material holder. The neutralizing material holder is disposed between the input port and the liquid output port.

Abstract: A system and a method for controlling twinned heating appliances are described. The system includes a first heating appliance and a second heating appliance. The first heating appliance includes a first blower and a first wireless communication unit. Further, the second heating appliance is operatively coupled with the first heating appliance as a twinned unit. The second heating appliance includes a second blower and a second wireless communication unit. The system also includes a primary control unit configured to receive speed data indicative of a speed of the first blower and speed data indicative of a speed of the second blower. The primary control unit is further configured to output a blower speed control signal to at least one of the first blower and the second blower to synchronize the first blower and the second blower.

Abstract: The disclosed technology includes systems and methods for controlling an air conditioning system. The method of controlling the air conditioning system can include receiving air temperature data from an air temperature sensor and determining that the air conditioning system should operate in a reheat mode based on the air temperature being less than a threshold air temperature. The method can include outputting a control signal to a first electronic expansion valve to close and thereby prevent refrigerant to flow through an outdoor condenser coil. The method can also include outputting a control signal to a second electronic expansion valve to open and thereby permit refrigerant to flow through a reheat coil.

Abstract: The disclosed technology includes systems and methods for reducing temperature overshoot of a heating, ventilation, and air conditioning (HVAC) system. The disclosed technology can include a thermostat having a temperature sensor and a controller. The controller can be configured to receive temperature data from the temperature sensor, determine whether a time since the heating cycle of the HVAC unit began is greater than or equal to a predetermined amount of time, and determine whether a current temperature is less than or equal to a low threshold temperature, the low threshold temperature being less than a target temperature. If the current temperature is less than or equal to the low threshold temperature, the controller can determine whether a capacity of the HVAC unit at the end of the heating cycle is greater than a threshold capacity and adjust a response setting of the thermostat by a predetermined adjustment amount.

Abstract: Systems and methods for improving efficiency in a heat pump system using redirected outflow air are provided. The heat pump may direct conditioned air, e.g., cooled air, into a duct for circulation throughout a room or building and may receive via ducting airflow from the room and/or building. The airflow received from the building may be closer in temperature to the air directed into the building than the air in the exterior environment. The air received from the building may be redirected using a conduit to condenser or evaporator coils for heat exchange with the coils. Using the air from the building instead of the air from the exterior environment may provide for more efficient heat exchange with the coils, e.g., evaporator coils, improving efficiency of the heat pump.
