TECHNOTHERM Infrared Heater X1 RF B

Series Infrared Radiation Panel ISP-B 351 RF Black with Radio Control

The TECHNOTHERM X1 RF B infrared heater utilizes infrared radiant heat via a black front panel. The heated surface emits warmth to room surfaces, which store it and evenly release it back into the air. The room climate remains calm and dry. A heat-insulated back increases efficiency. Temperature control is ErP-compliant via radio or internet systems, depending on the model. The “RF” radio receiver is integrated.

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

Certified Safety: TECHNOTHERM products are regularly tested by TÜV Nord for GS conformity.

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

Pleasant, healthy warmth

ISP infrared heaters primarily emit radiant heat. They warm walls, floors, and furniture, which release this heat evenly into the room. This feels similar to the warmth of the sun, without drafts and with stable humidity; dust remains largely undisturbed.

Design object instead of a radiator

Frameless glass and metal fronts, mirror variants, Art-Line motifs, and LED versions transform the panels into visible design elements. Various sizes, colors, and motifs suit living rooms, bathrooms, offices, or practices. The panels are suitable for wall and ceiling mounting, horizontally or vertically.

Reliable control and Ecodesign compliant

All infrared heaters are delivered ErP-compliant. An industrial plug allows connection only in combination with a suitable temperature control, such as room thermostats or radio/smart home solutions. This ensures operation remains within Ecodesign specifications and prevents incorrect operation without control.
