Rointe electric radiators are manufactured with high-quality components and include extended guarantees for your peace of mind. The Sygma radiators are a competitively priced digital heating solution with 24/7 programming. It’s available in 10 sizes, including a reduced height radiator for smaller spaces and walls.


The Sygma electric radiator surrounds your home, hotel, residence or school with comfortable, even and efficient heat, thanks to its advanced technology – Optimizer Energy Plus. This patented technology consumes on average only 40% of its nominal power to maintain the temperature at 21ºC (according to independent tests). With this basic radiator range, you will benefit from greater energy efficiency, through a high-quality product at an affordable price.


The Sygma radiator offers unbeatable control over temperature and relative humidity, all within an economical product. Using infrared communication, it can be controlled using the Rointe AIR Control remote (sold separately) for easy programming. The Sygma wall-mounted radiator also includes a compact keypad with mechanical buttons and a 1.77″ TFT screen for quick and simple control.


The design of this advanced radiator, both in the standard and short version, is distinguished by its interior fins that favour natural convection for even warmth and a high-heat transfer thermal fluid (oil-filled). The quality and purity of the aluminium body allow the Sygma electric radiator to function at a lower surface temperature (43ºC once steady working rate achieved). With a modern design and 24/7 programming, the Sygma electric radiator is designed with you in mind.



Optimizer Energy Plus

Optimizer Energy Plus includes intelligent microprocessors to send the necessary amount of energy needed at each moment. It improves efficiency and consumption savings, keeping temperatures stable by using on average only 40% of the product nominal power (set at 21ºC over 24 hour period).

Infrared control

The Sygma heating range has infrared communication (send). It offers an easy way to program and schedule products in this range, as well as controlling the temperature or viewing the active modes of these products.

Temperature stability (only ± 0.25°C variation)


Includes template, installation kit and brackets

⁽¹⁾ In tests carried out in the Center for Testing Innovation and Services (CEIS) laboratory, the Sygma 1,430 W radiator with Optimizer Energy Plus was tested. These tests concluded that to maintain a room at 21ºC with a variation of only ± 0.25ºC for a period of 24 hours, this radiator needed an average of only 572 W or 40% of its nominal power. This percentage is what we define as the equivalent consumption coefficient. If we multiply the nominal power of the product by the equivalent consumption coefficient, we obtain the effective power.

Radiator installation recommendations:

  • Rointe radiators are designed to be wall-mounted, with fixings, brackets and a template supplied as part of the product.
  • Rointe radiators must be positioned vertically, but not under a window. This would affect the thermostat reading, potentially causing excessive consumption.
  • Rointe radiators sized for a particular room should not be installed in another unless the conditions (such as size, ceiling height etc.) are extremely similar.
  • Rointe radiators are best placed on a wall away from drafts like doors and with sufficient space so the radiator won’t be obscured by furniture. This allows the best natural convection cycle for even and efficient heat.
