Long-lasting feel-good warmth

The fireclay storage core absorbs a lot of heat and releases it evenly over many hours. This keeps the room pleasantly warm, even when electricity rates are high.

Low heating costs thanks to favorable tariffs and PV

The room storage heater charges in defined time windows at low electricity prices and automatically adjusts the charging time to the heat demand. Ideal in combination with dynamic tariffs and your own photovoltaic system.

Comfort through smart control

The electronic, internet-enabled thermostat with weekly programs and app connectivity regulates heating output precisely. Features such as adaptive control, charge indicator, and open-window detection increase comfort and save energy.

Special features of partial storage heating

Constant heat, robust design, smart control

Uniform heat distribution – The spot-welded ribs ensure constant convection and improve heat emission across the entire surface of the device. At the same time, this process increases the stability and service life of the radiator.
Long-lasting storage effect – The integrated fireclay storage core absorbs energy and releases it evenly over several hours – even during intermittent power interruptions.
Convenient remote control – Temperature and schedules can be easily regulated via smartphone or desktop – ideal for individual use and efficient operation. This ensures maximum control – even when on the go.
