INFRARED WARMTH The right solution for each application.


Compared to other heaters, infrared heating systems have a high end-energy efficiency. This is because they generate the required warmth directly where they are installed. An infrared heating system suffers none of the heat loss in water-borne heating systems while transferring the warm heating water from the boiler through the pipes to the radiators. Thanks to this improved use of heat energy, radiation heaters provide a permanent reduction in heating costs.

The direct heat radiation from infrared heating means that inhabitants believe that the room temperature is 2-3 degrees warmer than it actually is. As a result, infrared heating requires less heat output than other heating systems, while at the same time also ensuring shorter heating-up times. This offers the consumer not only fuel savings, but also the possibility of more sustainable, intelligent heating. Each temperature degree lower means a reduction in energy consumption of approximately six percent.


Infrared heating systems can be coupled with photovoltaic systems on the roof. The required current is no longer taken from the mains socket, as the solar cells provide energy into the infrared heating system. Building owners have become independent of the public power supply, and operate their radiation heating with their own, more or less free ecologically friendly power from the roof. New buildings are subject to the German Renewable Energies Heat Act (EEWärmeG) with regard to building heating. This defines the proportion of renewable energy to be used in heat generation. This is where connecting the photovoltaic system to your infrared heating makes sense.


the ideal replacement for night storage heaters ETHERMA infrared heating

More than 500,000 obsolete night storage heaters supplied German households with heat in September 2016. Due to the obsolete technology of this type of heating, however, homeowners and property owners consume more energy despite reduced night-time electricity rates than with modern heating systems - which is unnecessarily high heating costs. This is where savings can be made by replacing heating with modern and efficient infrared heating. High-quality infrared heating panels not only save energy and are environmentally friendly thanks to green electricity, they are also particularly efficient thanks to their innovative technology.

THE RIGHT PLANNING Get yourself an advantage!

It is also important that the infrared heater is properly planned and dimensioned. For this we always advise you to a professional advice, because it is crucial:

  • the optimal power (watts) of the infrared heaters
  • the exact positioning of the infrared panels
  • the number of required devices
  • a heating load calculation for each room

Otherwise it can be expensive quickly. This applies to under-dimensioning as well as over-dimensioning.
We at ETHERMA therefore always consider the individual case exactly. Contact us now and we will advise you!

Well insulated buildings When does an infrared heater make sense?

An infrared heater can not be recommended for every household, as they are powered by electricity and can therefore be a costly way of heating if they are not planned correctly. This often applies in old buildings, which have a high heat requirement per m² and do not have the necessary insulation of walls and windows. However, if the premises are adequately insulated and the heating demand in the area of a passive or low-energy house (or better), the use of infrared heating is efficient and economical. Especially since there are no maintenance and service costs or fuel is needed.

This shows that the structural requirements are an essential factor for the question of the costs of infrared heaters:

  • Insulation of the building and insulation of the windows
  • Number of external walls in the room to be heated
  • Room size

Renovation made easy!

While modern gas heaters or heat pumps require appropriate piping to transport the heating water, infrared heaters only require access to the outlet. Especially in older buildings that were supplied with heat in the past without water heating, heating pipes and heating circuit manifolds are not available and would have to be laid first. This structural effort is eliminated in an infrared heater, so that a heating modernization is done quickly, inexpensively and without dirt.

Compared to an infrared heater, water-based heating systems react more slowly to changing temperatures, since the heating medium (water) must first be heated before it can release its absorbed heat to the room. This process is eliminated with radiant heating.


The word "infrared" (infra, lat. = beyond) makes it quite clear that we are referring to a range of electromagnetic radiation which lies beyond the red end of the visible light spectrum and is therefore free from UV radiation.

ETHERMA creates visionary technical devices to make optimum use of the highly efficient infrared radiation as a source of heat. This is why we have the right ingenious warmth solution for every wave range.

The individual infrared ranges differ in terms of the length of their waves.
