A heating element can be moved by a machine, such as a machine including a fan, an actuator, or a conveyor. The heating element can be attached to or embedded in a fan or an actuator. Or, the heating element can be attached to or embedded in a conveyor belt of a conveyor. A combination of a heating element and a mover machine can be further combined with a heat radiating wall. The heating element and the machine can be arranged behind the wall. And, when the heating element and the machine are powered on, the heating element converts electrical energy into heat, which increases the temperature of the wall, and the machine moves the heating element to be next to different areas of the wall. This allows for heat to be distributed more evenly to the wall than it would be if the heating element did not move.

A climate control system is operated by receiving climate information from climate control input devices at one or more plugin modules. The climate information is communicated from the plugin modules to a main control unit, which determines operating instructions for climate output devices and air inlets. When it is detected that the main control unit is not operational, the control system switches to a standby control unit if so equipped. The climate information is then communicated from the plugin modules to the standby control unit. The standby control unit determines operating instructions for the climate output devices and air inlets based on the climate information. When it is detected that the standby control unit is also not operational, the plugin modules switch to an autonomous mode such that operating instructions for the climate output devices and air inlets are determined by the plugin modules.

An electrical water heater that receives a load shedding request signal uses a temperature sensor that is positioned so as to measure a water temperature in a lower area of a tank of the water heater. A controller continuously determines a salubrity index of the water heater as a function of the temperature measured by the sensor and a time measurement The controller decides to interrupt an electrical power supply of the water heater through a switch so as to interrupt or not interrupt an operation of the water heater upon receipt of the load shedding request signal and only if the salubrity index meets a preestablished criterion.
