Thermotec AeroFlow - Electric Radiators

AeroFlow® electric heater with fireclay storage core

Surface storage heaters with a fireclay storage core combine the advantages of classic storage heating with those of direct heating. They heat up quickly and maintain heat without the need for electricity.

The heart of our AeroFlow® surface storage heater is the specially developed internal firebrick. It in turn contains the heating conductors. In contrast to conventional electric heaters, it is not the steel jacket that is heated but the stone.

The heat enters the room directly via the slats above. At the same time, the warm storage stone draws in cold air from below, heats it up, and releases it back into the room at the top – so-called convection heat.

When the desired room temperature, which you enter via the thermostat, is reached, the radiator switches off and the firebrick continues to emit heat without consuming electricity.

Thermotec AG

For more than 20 years, Thermotec AG has been developing and producing the most modern electric heaters for worldwide use in the heart of Europe. Thermotec AG engineers aim for the highest possible efficiency and the technicians for the highest quality processing.
  • Future-oriented development team
  • Quality without compromise
  • 100% Made in Germany
  • Long-term manufacturer guarantee
  • Company of the year 2015

At the Thermotec AG headquarters in Vierkirchen, Germany, they manufacture every electric heater from A to Z. That means they cut the fully galvanized steel into precisely fitting pieces and thus form the surface with the flow-optimized fins from one piece. The same happens with the side panels and radiator covers. The individual parts are then powder-coated in a specially developed process.


Thermotec AG was awarded the Entrepreneur’s Prize in 2015.
