säteilylämmittimen
Säteilylämmitin, also known as a radiant heater, is a type of heating device that transfers heat through infrared radiation. Unlike convection heaters that heat the air, radiant heaters directly warm objects and people in their line of sight. This makes them particularly effective in spaces with drafts or high ceilings where air heating would be inefficient. The heat is emitted from a heated element, typically a ceramic or quartz tube, which glows red hot and radiates infrared waves. These waves travel through the air without significantly heating it, and are absorbed by surfaces they encounter, such as walls, furniture, and skin. This direct transfer of energy creates a feeling of warmth almost immediately.
Radiant heaters are commonly used for supplementary heating in homes, workshops, garages, and outdoor spaces like
