Radiátory, often referred to as radiators, are heat exchangers designed to transfer thermal energy from a fluid, typically hot water or steam, to the surrounding air. They are a common component of central heating systems in buildings, providing warmth by radiating and convecting heat into a room.

The basic principle of a radiator's operation involves the circulation of a heated medium through its internal passages. As the hot fluid flows through the radiator's pipes or fins, heat is transferred to the metal surfaces. These surfaces then heat the air in contact with them. This heated air rises due to convection, while the surfaces also emit infrared radiation, further contributing to the room's temperature.

Radiators can be constructed from various materials, with cast iron, steel, and aluminum being the most prevalent. Cast iron radiators are known for their durability and slow heat release, maintaining warmth for a considerable time after the heating system is turned off. Steel radiators are often more lightweight and heat up faster, while aluminum radiators offer excellent thermal conductivity and efficiency.

The design of radiators has evolved over time, from the traditional column radiators to more modern panel radiators and decorative designer radiators that can complement interior aesthetics. The size and number of radiators required for a space are determined by factors such as room dimensions, insulation levels, and desired temperature. Regular maintenance, such as bleeding to remove trapped air, ensures optimal performance and efficiency.
