Pleasant, long-lasting warmth

The partial storage heater heats internal fireclay storage stones. Once the target temperature is reached, the power supply switches off and the storage releases the heat again over a longer period. This ensures even room temperatures and a mix of radiant and convective heat, which is perceived as particularly comfortable.

Efficient operation and smart control

Due to the storage concept, the device does not run continuously but heats in intervals. At TECHNOTHERM, an integrated digital thermostat with timer functions and app or cloud connectivity controls the energy supply very precisely. TECHNOTHERM also highlights proven energy efficiency in a study from England. This reduces electricity costs and increases comfort because the desired temperature is maintained accurately.

Flexible installation and ideal for modernization

The units are available for wall mounting or as mobile units on feet or castors. Connection to a standard Schuko socket or via fixed wiring is possible. Many output sizes and RAL colors adapt the heater to the room and interior. Internet-enabled controls and energy managers can integrate self-generated electricity from photovoltaics on request.

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.

Instant heat & storage effect

Direct heating technology and the storage core work together for fast, long-lasting heat.

Even indoor climate

The combination of radiant and convective heat ensures comfortable temperatures without drafts.
