The centerpiece of our AeroFlow® ground-source heat pump is the specially developed internal chamotte stone. In it, the heating conductors are located. Unlike conventional electric heaters, therefore, the steel casing is not heated, but the stone itself. The heat is transferred directly into the room via the panels above it. This way, the heater draws cold air from below, warms it up, and then transfers it back into the room – the so-called convection heat.
When the desired room temperature you have entered via the thermostat is reached, the heating element shuts off and the shale stone continues to release heat without consuming any electricity.
Direct radiant heat, convection, and heat dissipation without a permanent power supply
A specially developed manufacturing process has improved the heat transfer of the heating elements to the housing. This means that the heater heats up particularly quickly and evenly. Furthermore, the streamlined ribbed surface of the AeroFlow® electric heater emits more radiant heat than devices with a flat surface.
All together, our ground-source heat pump ensures pleasant room temperatures and helps to save on energy costs: The specially designed blades heat up quickly and evenly without creating dust, and our chamotte stone stores the heat particularly well, allowing the temperature of the heating unit to remain constant for a long time and preventing the need to heat up again.
Under normal circumstances, more heat is generated in the upper area of a heater. This then causes an uneven distribution of the heat throughout the room. However, to ensure that the heat is distributed evenly throughout your home, the AeroFlow® surface-storage heater has separate heating zones with different heating outputs at the top and bottom.
Each heating segment has its own temperature switch
FlexiSmart Pro – manual control, heating plan control on the device or via app control
FlexiComfortApp – Radio control

All the workpieces and elements we use are of the highest quality and tested to ensure durability and safety. We give you a 30-year manufacturer’s warranty on them. We can do this with a clear conscience, because we manufacture the radiators in our production facility in Saxony – from the bending of the steel to the powder coating and final assembly – in a cast mold.
