Techniques regarding water heating control and hot water tanks are provided herein. For example, one or more embodiments described herein can regard a device or system for water tank heating regulation. The system can comprise a processor that executes computer executable components stored in a memory. The system can also comprise a mounting component that couples the system to a thermostat of a water heater. The system can further comprise an adapter component that attaches to a temperature adjustor of the thermostat; and a configuration component of the computer executable components that, when enabled by the processor, causes the adapter component to move the temperature adjustor make a temperature change at the thermostat.

A dual-function water conditioning system and method thereof are disclosed that heat or cool water on demand to overcome seasonal discomfort. The system includes a thermally insulated water conditioning chamber coupled to a heating mechanism and a refrigeration-based cooling mechanism, governed by an electronic controller. A user interface or remote application allows selection of a target temperature, and the controller regulates conditioning to deliver water through outlet while being integrable with existing pipelines without loss of pressure. The invention further relates to intelligent water mixing and control systems that adapt faucet operation to seasonal variations in supply temperature, thereby preventing user confusion and ensuring year-round comfort. Additional features include a detachable phase change material (PCM) cooling attachment (130), IoT connectivity, adaptive learning, and safety measures such as thermostatic mixing, leak detection, and pressure/vacuum relief for efficient and hygienic operation.

A water heating unit includes at least one electrical heating element, a relay configured to allow electrical current to flow through the at least one electrical heating element when the relay is in a closed state and to prevent electrical current from flowing through the at least one electrical heating element when the relay is in an open state, and a controller in communication with the relay to switch the relay between the closed state and the open state. The controller is configured to perform at least one of: maintaining the relay in the open state upon receiving a signal indicating that another water heating unit of the plurality of water heating units is in a heating mode and, upon placing the relay in the closed state, transmitting a signal in order to prevent another water heating unit from entering into a heating mode.

A heating structure, a switchable heating/cooling air blower, and a method for switching between a heating mode and a cooling mode are provided. The heating structure includes a switching motor, a heating assembly, a connecting base, and a swing blade. A rotating component is disposed at one end of the heating assembly and is connected to the switching motor. The connecting base defines a guide groove. The swing blade includes a first connecting shaft and a second connecting shaft, the first connecting shaft is hinged to the rotating portion, and the second connecting shaft is inserted into the guide groove. The heating assembly is driven to rotate by the switching motor, so that the heating assembly is capable of swinging by a certain angle to enter or exit an air outlet, so as to switch the switchable heating/cooling air blower between the heating mode and the cooling mode.
