lämpöpatteris

Lämpöpatteris, commonly known as radiators in English, are devices used for heating buildings. They function by circulating hot water or steam, which then transfers heat to the surrounding air through convection and radiation. The hot water or steam is typically generated by a central boiler. As the hot fluid flows through the radiator's internal channels, it heats the metal fins or surface of the radiator. This heat is then released into the room. Convection occurs as the air near the radiator is warmed, becomes less dense, and rises, while cooler air from the room sinks to take its place, creating a continuous circulation of heated air. Radiation also plays a role, with the hot surface of the radiator emitting infrared energy that warms objects and people in the room directly. Lämpöpatteris are usually made of metal, such as cast iron, steel, or aluminum, chosen for their durability and heat conductivity. They come in various designs, from traditional column radiators to more modern, compact panel radiators, allowing for aesthetic integration into different interior styles. The temperature of a lämpöpatteri can be controlled by adjusting the flow of hot water or steam to it, often through a thermostatic valve.
