The infrared is widespread in everyday life (industry, health, home). In this article we are going to focus only on the field of heating.
The so-called “infrared” heaters are electric radiant heaters. What distinguish them from classical radiant heaters is their performance.
Most heaters (and more generally heat emitters) produce heat mainly by convection. The air heats up in contact with the heat emitter then accumulates under the ceiling and progressively fills the volume of the room. The principle of the infrared is, instead, to minimise the convective effect and maximise the radiation effect. Read more about the convection.
Therefore the infrared heating is a radiant heating which performances allow to produce at least 50% of infrared (so 50% of convection).
But what is the radiation? It is the fact of transmitting the heat without contact. Well known is the principle of the sun in winter that heats you up while you are outside and the temperature shows 0°C – the heat reaches you without contact. This principle was discovered by physicist Herschel in the 18th century. The infrared heaters reproduce this principle based on electricity.
It is sometimes wrongly understood that if you cut the heating (thus the radiation)….
