radiant heating panels
Principle of infrared heating
Whereas in convection heating the air is warmed by a convector
and then transfers heat as it fl ows over the objects that are to be
heated (walls, furniture), radiant heating panels transfer heat
mainly through radiant energy. Upon encountering objects (walls,
furniture, fl oor), radiant energy is partly refl ected (approx. 15%),
but most (approx. 85%) is absorbed by the objects. This radiant
energy is converted to heating energy as it raises the temperature
of the objects, which then transfer heat to the cooler air by convection.
Thus, the air is heated by the warmer objects.
Thanks to unique technology Silicating, hight temperature radiant
panels reach high emissivity up to 0,98.
The principles mentioned create
the following advantages:
• the surface of the radiant panel radiates a fl ow whose
spectrum lies mostly in the band of wavelengths
greater than 5 micrometers, and is thus absorbed
to a large degree by the human body: people are
thus heated in a manner similar to objects.
• when the radiant fl ow heats objects up to a level
of 20–22 °C, heat comfort can be achieved
even with air temperatures of 18–19 °C, and this
leads to energy savings of at least 18–24 %.
• radiant panels make temperature distribution in a room
vastly more vertically balanced – only a –1 to –2
degree difference between the fl oor and the ceiling
(for convection heating, meanwhile, the difference
is given as 1 °C per mere 30–50 cm of height).
• there is less fl ow (whirling) of air in the heated space, so dust
particles also whirl less, thus reducing the risk for a number
of illnesses—asthma, mucous membrane infection, etc.
• a higher wall temperature means a lower possibility for
surface condensation; room humidity is not lowered.
• glass is not “transparent” (we might say “transthermant”)
when it comes to radiation with wavelengths over 3 and
thus the radiant fl ow is not lost through windowpanes.
• the panels do not need any maintenance
Unique technologies
Fenix uses unique, state-of-the-art technologies for fi nishing panel surfaces (Thermoquartz and Thermocrystal for low temperature panels and
Silicating for high temperature panels).
