Rointe Sygma radiators are a competitively priced digital heating solution with 24/7 programming.

Sygma: economical radiators

The Sygma 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 Rointe Sygma radiators you will benefit from greater energy efficiency through a high-quality product at an unbeatable price.

Optimizer Energy Plus

Patented technology that optimises the energy consumption of the radiator. A non-consumption coefficient of 60% of the nominal power is achieved.

Innovative design

The design of the Sygma radiators, both in the standard and short version, is distinguished by its interior fins that favour natural convection for even warmth.

Low temperatures

The quality and purity of the aluminium guarantees the Sygma radiator functions at a lower surface temperature (43ºC once steady working rate achieved).

Extended guarantees

Customer satisfaction is important to us. That's why Sygma radiators include 10 years guarantee on the aluminium body and 3 years on electronic components.


Smart energy for maximum comfort.

Sygma radiators include Optimizer Energy Plus – a patented Rointe technology designed to maximise efficiency and keep temperatures stable. Studies have proved it only uses 40% of the product nominal power on average, set at 21ºC over a 24 hour period.


This specialised low consumption technology includes a state-of-the-art microprocessor that sends the necessary amount of energy needed for each moment, improving efficiency and consumption savings.


Optimizer Energy Plus stabilises room temperatures within a variation of only ±0.25ºC, compared to ±2ºC in other heating systems.


Individual control.

The individual control of Sygma radiators allows you to set the time and temperature of each unit individually, achieving maximum comfort whilst saving on your consumption.


You can schedule more Comfort mode hours in spaces such as the living room or kitchen, which has a higher level of daily activity. On the contrary, in other areas such as the bedroom, which are usually only used for a limited period at night, it is much smarter to set lower temperatures by activating the Eco mode.


The easy way to program your Sygma radiator.

The new access menu on the Sygma radiator has been designed by Rointe’s R & D department for easy programming. Using smart icons, you can access all the functions quickly to keep your heating perfectly programmed.


The Sygma radiator includes a compact keypad with mechanical buttons and a 1.77″ TFT screen for easier control.


Exclusive functions that help you save.

All Rointe radiators include energy-saving features that help you reduce consumption, such as Open Windows.


This function is activated when the product probe detects a decrease in ambient temperature of at least 4°C within a 30 minute time period. It then automatically activates the Anti-frost mode for a period of 2 hours, preventing excessive consumption.

Even and comfortable heat throughout.

The heat dissipation of a radiator is fundamental to maintain an optimum standard of thermal comfort.


To achieve maximum heat distribution, high-quality aluminium is used in Sygma radiators that has been specially designed using Computational Fluid Dynamics. This results in higher thermal conductivity, optimising natural convection for better product performance and faster heating times.


The special design of Sygma radiators (balanced heating elements with internal fins), facilitates efficient natural convection. This helps to reach the desired temperature quickly, providing stable and even heat throughout the entire room.



The AIR Control remote has been specially created to facilitate easy use and programming of Sygma radiators.


Using infrared communication, you can easily send commands to your product for quick programming 24/7. And with a transmitting range of up to 3m, you can lock your product remotely to prevent misuse, helping you save energy.

Discover the Rointe heating products and sizes you need for your installation in a few easy steps.

Reduced height for smaller spaces.

Within the Sygma range, we have designed a reduced height radiator (only 420 mm high) – a space-saving solution for smaller spaces and walls. The Sygma short is ideal for conservatories, balconies or walls where, due to its height, a radiator with normal dimensions cannot be installed.
