Lämpöparistojen

Lämpöparistojen, commonly known as radiators, are heat emitters used in hydronic heating systems. They transfer thermal energy from hot water circulating within them to the surrounding air, thereby warming a room. The fundamental principle behind a radiator's operation is convection. As water, heated by a boiler, flows through the radiator's internal channels, it warms the metal surfaces. These heated surfaces then warm the air in direct contact with them. This warmer, less dense air rises, and cooler, denser air from higher in the room descends to take its place, creating a continuous convective current that distributes heat throughout the space.

Radiators are typically constructed from metal, such as cast iron, steel, or aluminum, chosen for its good thermal conductivity and durability. They come in various designs, from traditional column radiators to modern panel radiators, each offering different aesthetic and heating performance characteristics. The surface area of a radiator is a key factor in its efficiency; larger surface areas allow for greater heat transfer to the air. The water temperature within the system also directly influences the heat output. Higher water temperatures result in hotter radiators and thus more heat emission. While primarily used for heating, some radiator designs can also incorporate features for drying clothes or acting as decorative elements within a room.
