Radiator

A radiator is a device used to transfer heat from a hot liquid or air to the surrounding environment, helping to warm a space. In heating systems, hot water or steam flows through the radiator's metal surfaces, which then radiate and convect heat into the room. The metal's conductivity allows it to efficiently transfer heat, while the design maximizes surface area for better warmth distribution. Radiators are common in central heating systems, providing consistent and controllable indoor warmth, especially during colder months.
