Consulting - Planning - Analysis

Infrared heaters are a low-cost alternative to all other heating systems. By choosing the right product, you can save a lot of money on the purchase and energy consumption.

That is why we inform you about

the physical principles of infrared heating,
the correct installation locations, with a heating plan if required,
the two different types of heating behaviour
and the important decision criteria for the selection of heating elements

Example:

Our service was called by a carer to see a seriously ill patient. Her wood-fired stove went out at night when no one was there to look after her and she was freezing. The patient had bought a cheap infrared heating element, but it did not give off enough heat. We determined with our infrared camera that the radiation temperature was only 42.6° - of course far too low to heat a room.

When we gave advice, we pointed out that you should only buy if the manufacturer can provide a test certificate showing the efficiency. If the efficiency is close to the maximum possible 70%, then it is a heating element that has the best heating effect with low energy consumption.

A heating element with this high efficiency always has a sufficient front radiation temperature. A manufacturer should only describe his element as an infrared heater if the radiation temperature is higher than approx. 70°C. It is still comparatively inefficient. It is still comparatively inefficient, because a heater with 140°C has a 16-fold higher radiant power according to the Stephan-Bolzmann formula of quantum physics!

As the radiation temperature decreases with the square of the distance, at low surface temperatures no more heat is noticeable even at a short distance. It is already dissipated upwards as convective heat. With these elements, the convective component is greater than the radiant component.

Technical advice

Choosing a highly efficient infrared heater is difficult given the wide range on the market and is only possible with sufficient technical expertise. We close this gap and offer you comprehensive and completely non-binding advice and help in any form.

Heating system planning

The installation location of the infrared heaters is important for energy efficiency. As a general rule, ceiling installation generates only minimal to no convection. Therefore, in addition to the efficiency of the heating system, this is the basic requirement for the lowest possible energy consumption.

But the placement in the room should also be chosen correctly. Wir bieten aus diesem Grund bei Auftragserteilung die kostenlose Planung auf der Basis eines Grundrissplans der Wohnung oder des Hauses an.

The floor plans can be sent as a simple sketch or as mobile phone photos by e-mail. We can prepare them technically so that they can be used as a basis for planning.

Cold/thermal bridge analysis

One of the most important criteria for low energy consumption is the insulation and airtightness of the building. As a service, we offer all our customers and interested parties free of charge (if we are on site anyway) or at cost price the Checking the building for the presence of cold bridges/thermal bridges to.

We use an infrared camera for this purpose. It is possible to create documentation.

We have found in such reviews that in particular leaky Door or window frames cool down the room. The draft moving convectively through the room also cools the area in the radiation angle of the radiator.

That is why something should always be done to prevent this type of energy loss. In picture no. 3, bottom right, a linen curtain has been hung and you can clearly see the difference in temperatures with this simple measure. The long duration of use results in considerable energy savings.

Since the energy costs are not higher with large heating elements, larger radiators can be chosen in case of poor external insulation, but in case of draughts It is better to seal the windows and doors.
