How it works
The principle of infrared heating
Infrared panels produce that exact part of infrared radiation needed to create a comfortable and warm feeling without harmful kinds of radiation.
INFRARED HEATINGg is the type of radiant heating i.e. transmission of energy from a heat source into the heated area where the source first heats the nearby objects (and people) and building structures and subsequently heating the air in the room. In comparison – conventional warm water heating first heats the air and only then the nearby objects (people) and building structures. While the air in the room has a tendency to stratify vertically – being the coldest at the bottom and warmest at the top.
Temperature distribution in the room – a comparison:
The flow of “heat” from the heater in the room – a comparison:

With conventional heating, With conventional heating, the heating element (HE) is placed under the window mainly due to better flow of the heated air from it towards the room, while not an insignificant proportion of the heat passes through the building structures into the external environment – behind the HE through a peripheral wall and over HE through the window – fig. 1a).
NB .: It should be noted that every correctly built window should provide “micro ventilation” for minimum air exchange in the room (this is also subject to humidity in the room, etc.) so heat losses through the building structure cannot be totally prevented. Most of the heated air flows into the room of fig. 1 b) and when it conveys heat, cooled air drops to the floor and is again heated by HE.
With infrared heating the heating element (HE) may be located anywhere, when appropriate on the ceiling – Fig. 2b) or walls – Fig. 2), while minimizing loss through the external wall of the room. And no heat transfer from HE to the heated area is that it first heats the nearby objects (and humans), and building structures, and only then it heats the air, which represents a further saving and advantages over the conventional heating.
NB.: It is generally true that each building structure has its own thermal properties, which are given by the constant heat loss – may any type of heating be used.
