How Radialight SIRIO Swedish Convector Heaters Work

What is an electric convector heater

Electric convector heaters are innovative solutions for home heating, combining energy efficiency, elegant design and ease of use. Among the most reliable options, the SIRIO Swedish Convector Heaters by Radialight stand out for their advanced technology and low energy consumption.

The main component is a high heat-exchange aluminium heating element, positioned at the bottom of the convector, which quickly heats the surrounding air. The electronic control system regulates room temperature and modulates heat output — and therefore energy consumption — ensuring comfort and safety.

Operating principle of SIRIO Swedish convectors

SIRIO convectors operate based on natural convection:

• Cold air enters through the lower grille.
• The aluminium heating element warms the incoming air.
• Hot air, being lighter, rises and exits through the upper grille, spreading heat evenly and quickly.

This process ensures fast, silent heating, without fans or moving parts, making it ideal for residential spaces and offices.

Digital control and energy management

SIRIO convectors feature a digital thermostat with LCD display, allowing you to:

• Set up to four heating modes.
• Adjust the Comfort temperature up to 35°C.
• Program weekly schedules to optimise energy consumption and comfort.

Each convector operates independently, reducing heat output during absence and increasing temperature only when needed.

Advantages of SIRIO electric convector heaters

• Easy installation: wall mounting and simple plug-in connection.
• Lower costs: no need for professional installers.
• Silent operation: natural air movement without fans.
• Precise temperature control: maximum deviation of just 0.5°C.
• Energy monitoring: daily and weekly consumption data displayed.
• Faster heating compared to traditional water radiators.
