Lämmityspattereita

Lämmityspattereita, often referred to as radiators in English, are a common component of central heating systems. Their primary function is to transfer heat from hot water circulating within them to the surrounding air, thereby warming the room. This heat transfer typically occurs through convection and radiation. Convection involves the heating of air that comes into contact with the radiator's surface, causing it to rise and circulate throughout the space. Radiation emits heat waves that directly warm objects and people within the room.

Lämmityspattereita are usually made of metal, most commonly steel or cast iron, due to their excellent heat conductivity and durability. They come in various designs and sizes to suit different heating needs and aesthetic preferences. Common types include panel radiators, which are flat-surfaced and often mounted on walls, and cast-iron radiators, known for their slow heat release and classic appearance. Underfloor heating systems, while not always visually represented as radiators, serve a similar purpose of distributing heat from a central source.

The operation of lämmityspattereita is typically controlled by thermostats, which regulate the flow of hot water to the radiators based on the desired room temperature. When the temperature drops below the set point, the thermostat signals the boiler to heat water and pump it to the radiators. As the radiators heat up, they warm the room. Once the desired temperature is reached, the flow of hot water is reduced or stopped, allowing the radiators to cool down. Proper maintenance, such as bleeding air from the system, ensures efficient operation.
