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 patios. They can be found in various forms, including portable electric units, wall-mounted panels, and even larger industrial heaters. Some models are designed for specific applications, such as bathroom heaters or patio heaters. The intensity of the heat can often be adjusted, allowing users to control the temperature and comfort level. Due to their direct heating method, radiant heaters are considered energy-efficient for targeted heating applications, as they don't waste energy warming unoccupied air.
