How Do Infrared Heaters Work?
Infrared heaters work differently from traditional convection heaters. Instead of warming the air, they emit invisible waves of heat that are absorbed directly by objects, walls, and people, just like natural sunlight, but without the harmful UV rays.
This means the warmth is felt faster and lasts longer, even when doors or windows are open. Because they don’t rely on circulating hot air, there’s no dust movement, no drafts, and no wasted energy heating unused space above head height.
Far infrared is especially gentle and effective. It penetrates just under the skin to provide a deep, lasting warmth that feels natural, comfortable, and efficient. It’s completely silent, safe, and perfect for both homes and commercial settings.
In short, infrared heating offers a smarter, healthier, and more economical way to stay warm — all while reducing your carbon footprint.
