vuokaissäteilijä

Vuokaissäteilijä is a Finnish term that translates to "flow radiator" or "convection radiator." It refers to a type of heating device designed to efficiently distribute heat through convection currents. Unlike radiant heaters that primarily transfer heat through electromagnetic waves, a vuokaissäteilijä circulates air, warming it and then releasing it into the room.

These devices typically consist of a heating element enclosed within a casing that facilitates airflow. Cold air enters the lower part of the radiator, passes over the heating element, becomes warmer, and rises to be expelled from the top. This continuous circulation creates a gentle flow of warm air throughout the space, providing a more uniform temperature distribution compared to some other heating methods.

Vuokaissäteilijät are often found in residential and commercial buildings, particularly in areas where consistent and comfortable heating is desired. They can be electric, powered by hot water from a central heating system, or even fueled by gas. Their design prioritizes quiet operation and energy efficiency, as they leverage natural convection principles. The term emphasizes the method of heat transfer – the radiator's function is to create a "flow" of heated air.
