lämmitysradiaattorit

Lämmitysradiaattorit, often referred to simply as radiators, are heat emitters used in central heating systems. Their primary function is to transfer heat from a boiler or other heat source to the surrounding air in a room, thereby warming the space. The most common type of radiator is the hydronic radiator, which circulates hot water or steam from a central heating unit. As the hot fluid flows through the radiator's passages, it heats the metal surfaces. These surfaces then radiate heat into the room and also heat the air through convection, which rises and circulates.

Modern radiators come in various designs and materials, with steel and cast iron being the most prevalent. Steel radiators are typically lighter and more efficient at heat transfer, while cast iron radiators offer excellent heat retention. The shape and surface area of a radiator are crucial to its heating capacity. Larger surface areas allow for more efficient heat dissipation. Installation typically involves plumbing connections to the central heating system and often includes valves that allow for individual room temperature control. Thermostatic radiator valves (TRVs) are a common feature, enabling users to set specific temperatures for each room and optimize energy usage. Radiators are a fundamental component of many residential and commercial heating systems, providing a reliable and effective method of maintaining comfortable indoor temperatures.
