That drives us


Are you with us?

The world is on the move. Energy supply with fossil fuels is becoming uncertain and expensive in the long term due to scarcer and scarcer resources. As we look to the future, many questions preoccupy us:

  • What are the energy sources of the future?
  • What will we use in the future to heat our homes most efficiently and in the most climate-neutral way?
  • What will the heating and heating control of the future look like?
  • How do we as Thermotec best meet customer demands for comfort, efficiency, design and quality?

The fact is that electricity from renewable energy sources and thus heating with electricity is becoming increasingly efficient.
We have to use e-heat cleverly. That's what we want and that's what we are doing!
Our highly efficient and high-quality electric heaters shall be the convincing heating system for more and more people in the future. We constantly follow and take into account the latest trends:

Storage of resources

Heat storage and electricity storage systems will help us in the future to balance out fluctuations in energy supply and demand. Our specially developed firebricks in our surface storage heaters already have such a "buffer function". They store heat particularly well and keep the temperature of the radiator constant for a long time without having to reheat.

Networking & Smart Home

The control of an electric heating system must be comfortable, cover many functions, but also be intuitive and easy to use. It must also be controllable via app and smart phone. And if the internet or wi-fi does fail, then the control directly on the device must work just as well, so that there are no cold feet. All these features are combined in our FlexiSmart and FlexiComfortApp controls.

Focusing on the essentials with foresight


The main focus is on the continuous further development and improvement of our radiators. At the same time, we consciously look at the needs of the user:
How to make the control of the heater easier?
How can power consumption be further reduced?
How can the appearance of radiators be designed?
What multi-device control is more effective for large users?


We are constantly working on developing new products and innovations. In doing so, the aim is always to further increase the comfort of the living spaces used and to make the most efficient use of the resources of our environment. Our vision is a maximum feel-good climate with minimum energy consumption - all while maintaining the standard high quality of Thermotec.


Part of our development work is the research into new heat storage facilities. The heat storage facility is the basis for the efficient use of generated thermal energy. Especially when using alternative heat generators, the heat storage facility should ensure that energy is consumed when it is needed and not when it is being produced.


Everything in-house: quality, professionalism and implementation strength

Our experienced engineers, who have been working for us for many years, develop concepts and prototypes based on the ideas and requirements of our customers with highest professionalism and passion. The intensive exchange of information with external laboratories and development partners guarantees the best solutions. The entire product development process takes place in-house, right through to the production-related implementation. This means efficiency and quality for us.

As the quality is the same at every stage of product development: through the selection of the best materials and the use of the latest production processes and production-related tests. Another important factor is that with in-house developments, the know-how remains within the company. This gives us control over the project flow and reduces dependencies. All development projects are technically documented in a comprehensive manner by responsible designers. This is the basis for future projects and improvements.


Hand in hand towards the best results

Not all areas of our development projects can be implemented in our company, which is why Thermotec is also integrated into the development network with other companies, universities, research institutions and experts. The cooperation of various specialists and departments ensures that new, interesting products, materials or projects are examined and evaluated from every perspective. For us, the basis of cooperation is mutual trust and a common understanding of values.

Many of our innovative projects have been so interesting that we have been able to benefit from public funding for further development. We are proud of that! Because apart from a lot of information, knowledge and solutions that we have gained during the development work, we were also able to register many protected patents related to the material of the heat storage material.

We are also open to further cooperation and networks in the future in order to develop the best solutions for our customers.

The development of heat storage modules based on phase change materials

Together with Institut für Nichtklassische Chemie e.V. (Institute for Non-Classical Chemistry) at the University of Leipzig (INC), heat transfer from heat conducting structures to the special heat storage material (Phase Change Material, PCM) was tested and its cycle stability was proven. With this material we have already built the first prototype for an absolutely new type of storage heater. This development project is still ongoing.

The development of a test stand for testing the service life of thermostats

Together with the Institut für Elektrotechnik at the Hochschule Zittau, we have developed a test stand for simulating the service life of thermostats under stressful climatic conditions for 30 years. Each newly developed controller has to be tested on this stand and meet the high requirements. This is an innovative approach in our industry.

Thermotechnical investigation

On 8 January 2018, our AeroFlow® MIDI 1950 electric radiator was measured at the Hochschule Zittau/Görlitz. The following radiator parameters were determined:
- The share of infrared heat in the total transmitted heat flux is about 25%. Therefore, 75% of the total heat flux is transferred as convection heat.
- The measured maximum value of magnetic induction of 50 Hz is only 9 μT (microtesla), which is significantly below the maximum permitted value of 200 μT (maximum value from the “Regulation on electromagnetic fields - 26. BImSchV, Annex 1“ State of: 26.03.2018

Performance and economic comparison of AeroFlow heaters and infrared heaters

The expert, Dipl.-Ing Peter vom Ort, stated that the Aeroflow system has twice the heat output of conventional infrared heaters in terms of the surface area.
In addition, the heating-up times of the Aeroflow system are only half as long as with conventional infrared heaters due to the design of the radiator. When it comes to economic efficiency, the Aeroflow radiator has significant advantages, as it gives about 48% lower investment costs for heating surfaces when purchased and copes with lower surface temperatures during operation. Compared to conventional classic infrared heaters, the maximum temperatures on the Aeroflow system surface are 60°C, whereas surface temperatures on pure infrared heaters can reach over 90°C.

If you stop getting better, you stop being good.
