The infrared heating process operates in a similar way to sunrays. The heater emits heat that is absorbed by objects within your room. The heaters gently increase the temperature in the room by heating clothes furnishings, skin, and various other objects in the space. Infrared light is not visible as it's outside that visible spectrum. Infrared light can be compared as sunrays in the sense that it heats your environment instantly.
