An infrared heater heats all solid objects, such as walls, floor, ceiling and furniture, by direct heat radiation. This heat is stored in the objects and slowly and evenly released into the room. We also feel this warmth on our skin, for example in the sun, a tiled stove or a campfire.
The latter in particular is a good example of how an infrared supplementary heater works. At the campfire you are not cold despite the low temperature, the heat radiation of the fire makes sure of that. The same applies to infrared heaters as supplementary heaters. Simply set it up in a cool room and switch it on – you’ll be warm in no time. It is not even necessary to heat the whole room. All you have to do is position the infrared heater so that the heat is radiated to where you want it to be warm.
