TECHNOTHERM Semi-Storage Heater S LT60 RF

Series Semi-Storage Heater TT-KS 700 S LT RF 60°C Surface with Radio Receiver

The TECHNOTHERM Semi-Storage Heater S LT60 RF is an electric direct heater with an integrated fireclay storage core, short heat-up time, and large storage volume. The surface temperature is limited to a maximum of 60°C, making it safe for use in social institutions. It provides an approximately half radiant, half convective heat output and is particularly suitable for permanently used living and working spaces. An RF series radio receiver is integrated. An external thermostat is required for control. Internet-enabled controls allow convenient programming, remote access, and integration of self-generated power. The devices are available in various sizes, protection classes, and color variants and can be installed either as a wall-mounted unit or a mobile freestanding unit. Wall mounting is standard.

High-quality technology – developed and manufactured in-house by TECHNOTHERM in Germany.

TÜV-tested: Our devices bear the GS mark for “Tested Safety” according to German standards.

Safe and EU-compliant: Our systems meet all European safety and environmental requirements.

Pleasant, long-lasting warmth

The semi-storage heater warms internal fireclay storage bricks. Once the target temperature is reached, the power supply switches off, and the storage unit releases heat over an extended period. This ensures consistent room temperatures and a blend of radiant and convection heat, which is perceived as particularly comfortable.

Efficient operation and smart control

Thanks to the storage concept, the device does not run continuously but heats in intervals. With TECHNOTHERM, an integrated digital thermostat with timer functions and app or cloud connectivity precisely controls the energy supply. TECHNOTHERM also highlights proven energy efficiency in a study from England. This reduces electricity costs and increases comfort by maintaining the desired temperature accurately. User argument ‘3: Flexible installation and ideal for modernization. The devices 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. Various power levels and RAL colors allow the heater to match the room and furnishings. Variants with low surface temperature are available.

Flexible installation and ideal for modernization

The devices are available for wall mounting or mobile use on feet or castors. Connection to a standard Schuko socket or via permanent connection is possible. Many power ratings and RAL colors adapt the heater to the room and decor. Variants with low surface temperatures are suitable for kindergartens, schools, and social facilities. Internet-enabled controls and energy managers can integrate self-generated electricity from photovoltaics upon request.
