(Excerpt from a lecture by Dr. Aron Flickstein)

Infrared radiant heat is a wave of the electromagnetic spectrum that encompasses energy of all wavelengths. It is an energy form that uses a conversion process to directly heat objects without heating up the surrounding air. Radiant heat is also called infrared energy (IR). The infrared portion of the electromagnetic spectrum is divided into three different wavelengths, measured in microns (μm):

0.07 – 1.50 = low IR-A waves
1.50 – 5.60 = medium IR-B waves
5,60 – 100,00 = long IR-C wave

In everyday life, for example, the sun is a source of radiant energy.

What happens when the sun disappears behind clouds?

Although the ambient temperature cannot drop as quickly, you will quickly feel cooler temperature. Since the clouds shield the sun’s infrared rays, it is immediately sensible that the heat radiation / infrared radiation is missing here. When the sky is clear, the wavelength of the IR radiation moves between 7 – 14 μm IR, where the IR radiation reaches the earth’s surface. The earth itself radiates infrared energy, but reaches max.10 microns.

For its stimulation the skin absorbs IR radiation selectively.
The infrared radiant heat in thermal systems is usually the same as what the human body produces and radiates. It also corresponds to the sun’s, however, without the proportionate UV radiation.
The discovery or the proof of the infrared radiation succeeded for the first time in 1800 by the German astronomer William Herschel through heating a blackened surface, which was illuminated with the IR portion of the spectrally decomposed solar radiation. The ability to heat substances is still used to detect infrared radiation.


Modern infrared heaters work according to the natural principle of the sun. Almost 100% of electrical energy is converted directly into infrared heat radiation by means of a heating element. It heats not the air directly, but the objects.
Remember the day you go out on a cold sunny day: it is pleasantly warm in the sun, but in the shadow you will feel immediately cold – even though the air temperature is the same.
This means you can keep the temperature in your rooms 2 – 3 degrees lower to have the same heat impact as from a conventional heater. This will save you a lot of energy!
With infrared heaters you have two sources of heat:

  • The indirect heat generated by the walls and furniture
  • The direct radiant heat of the infrared heater, which you can still feel up to 3 – 4 meters away.

As the infrared heat radiation also hits the walls and is absorbed by them, the walls dry, insulate better and no mold fungus can develop.
Achieving energy efficiency and thus saving on heating costs is our endeavor!


Conventional heaters work by heating water with fuel (oil, gas, pellets). The hot water passes through the pipes, where part of the heat is lost. Water is heated inside a radiator, which in turn heats the surrounding air.
The heated air rises upwards, which causes the air on the other side of the room to be pushed down over the floor until it is reheated by the radiator and rises again. The air in the room starts to circulate.
This system creates not only undesirable thermal coating (the upper part is warm, the lower part cold), but also the dust on the floor is stirred up and makes life difficult for allergy sufferers.
This technology is therefore very ineffective, no matter how efficient the boiler is and how well insulated the heating pipes are. You always have a heat loss on your way to the radiator and you always have the thermal coating.



The conventional water-based heating system consists of:
– heating, combustion or heat pump
– control for boiler
– chimney
– domestic hot water storage
– pump station & pump
– membrane expansion vessel
– pressure gauge
– countless valves
– infinite number of pipes
– radiator
– extra space for technology
– rotatable thermostats
– safety valves
– thermosyphon
– plumber
– infinite number of sensors
In the end you have very expensive planning for the heating system.


The modern trend-setting independent infrared heating system consists of:
– solar cells
– inverter
– battery storage
– electricity meter for supply and feed
– infrared radiators
– electronic thermostats
– hot water treatment (water heater or boiler)
– power lines
