Portable radiant heaters typically use electric coil or quartz tube heating elements to heat small spaces quickly—almost instantly. During heating, electric radiant heaters send out infrared radiation (IR) heat waves—just like the sun—to warm nearby objects and people. Radiant heaters are good choices for spot heating because they deliver quick, focused warmth to areas within their line-of-sight. While these heaters can be used to warm entire rooms, they may take some time to create an evenly heated space. Consider using portable radiant heaters for comfortable warmth while you lounge in your favorite chair, sit at your desk, or work at a workbench.
