The Principle
At the heart of the AeroFlow® ceramic storage heater is an internal fireclay brick with heating elements running through it. Unlike conventional electric heaters, it is the stone that heats up, not the steel casing. The heat is transferred directly into the room via the fins, with cold air being drawn in from below and released as warm air at the top – this is known as convection heat.
When the heater reaches the desired room temperature, it switches off automatically, while the fireclay brick continues to emit heat – without additional power consumption. Thanks to the specially developed fins and the storage brick, the temperature of the heater remains constant, so reheating is often not necessary.

Efficient tiled stove heat thanks to a fireclay core
In conventional heaters, more heat often accumulates at the top than at the bottom, leading to uneven heat distribution. Our AeroFlow® electric storage heaters, however, have separate heating zones with different wattages, ensuring an even distribution of heat throughout the room.

Smart Control
Today's new buildings and modernized old buildings should be equipped sustainably, energy-efficiently, comfortably, and economically. Our heaters feature smart control, allowing for easy operation via a user-friendly app. This enables you to control the heaters even when outside of your Wi-Fi network. Among other things, the heating adapts optimally to your lifestyle through the use of heating programs. This way, you can enjoy pleasant warmth at all times while saving on heating costs.
Flexible for all applications
Whether you want to heat unused rooms without connected radiators or need to bridge a central heating system failure or weaknesses – electric heating offers a flexible solution for numerous applications.
In times of rising gas and oil prices, electric storage heaters are also an attractive alternative to conventional fossil heating systems. Especially if you own a photovoltaic system, it can be more economically advantageous to use the generated electricity directly on-site instead of feeding it into the grid.
Electric storage heaters like the Aeroflow Smart are ideal, for example, for rooms that are not used regularly. Thanks to their low acquisition and installation costs, they enable the economical use of such areas during the cold season.

Standard control on the device (FlexiSmart)
Standard control is directly on the device. Based on the functionality of the classic rotary control, you set the desired room temperature directly on the radiator using a digital thermostat. The built-in temperature sensor switches off the heating once the target temperature is reached.
Simple and straightforward – ideal for those who prefer direct control or want to use individual devices independently.
Perfect for those who...
- prefer simple on/off switching directly on the device without an additional remote control
- have no need for complex control systems or apps
- desire quick and uncomplicated adjustment of room temperature
- wish to maintain individual control over each radiator
- are looking for a straightforward solution for rarely used rooms

Smart control via app (FlexiSmart Pro)
With the FlexiSmartPro control, you can transform your heater into a smart home device that can be conveniently operated via smartphone or tablet. Simply connect your heater to Wi-Fi and you can control your radiators comfortably from anywhere, at any time, via the app. The Smartheat4U app, specially developed for FlexiSmartPro, offers a user-friendly interface that allows you to effortlessly program your heater and adjust the temperature as desired, even if the heaters are installed in multiple residential units.
By creating individual heating schedules, you can flexibly set temperatures according to the time of day to use energy efficiently. Simply connect the digital thermostat to your Wi-Fi module and enjoy full control.
You don't need any additional devices or interfaces to integrate the FlexiSmart Pro heater into your Wi-Fi network. Manage your heating devices effortlessly and customize them with just a few clicks on your smartphone. Enjoy the benefits of intelligent heating control without complicated installations or expensive additional devices. With FlexiSmartPro control, you have complete control over your heating system.
Perfect for anyone who...
- is looking for a flexible heating control system that offers both manual and smart options
- wants to install a smart heating solution without complex installations or additional devices
- wants to benefit from the advantages of convenient and flexible heating control via app
- wants to set up individual heating schedules for efficient energy use
