How is the temperature of a heated space typically maintained at the desired level?

Maintaining the temperature of a heated space at the desired level primarily involves controlling the heat supply effectively. This process includes using thermostats to regulate the temperature by modulating the amount of heat produced by a heating system, such as radiators, underfloor heating, or heat pumps. By turning the heating on or off or adjusting the intensity of the heat provided based on the temperature readings, one can ensure that the space remains comfortable and energy-efficient. Thus, controlling the heat supply is crucial for achieving and maintaining a stable and comfortable indoor environment.
