Enhanced Dual-Fan Efficiency: Two PRO-5 fans deliver greater airflow coverage for radiators 1100 mm and wider, ensuring faster room heating.
Automatic Temperature Activation: Built-in thermostat and sensor start and stop both fans automatically for consistent heat distribution and energy savings.
Energy & Cost Reduction: Improves radiator performance, allowing lower thermostat and boiler settings while maintaining comfort.
Low Power Draw: Consumes just 3.3–6.6 W combined, offering high energy efficiency with minimal running cost.
Quiet Operation: Operates below 20 dBA, ideal for use in bedrooms, lounges, offices, and other occupied environments.
Fast, Tool-Free Installation: Magnetic mounting enables simple fitting to single, double, and column radiators without modifications.
Expandable System Design: Compatible with Radboost Extension accessories to increase airflow across extra-wide radiators.
The Radboost Radiator Booster Fan Double Pack enhances radiator efficiency and heat output using dual PRO-5 fans for increased airflow coverage. Designed for radiators 1100 mm or wider, this twin fan system circulates warm air more effectively, helping rooms heat up twice as fast while reducing energy use by up to 30%.
Each Radboost unit attaches magnetically to single, double, and column radiators with no tools required. The system installs in minutes using built-in magnetic mounts and can be configured for a range of radiator types, including most non-standard designs.
The integrated thermostat and external sensor automatically control both fans. When the radiator reaches operating temperature, the fans start automatically, distributing warm air evenly across the room. Once the radiator cools below 23 °C, the system shuts off to save energy.
By improving heat circulation, the Radboost Double Pack reduces reliance on high boiler settings and helps maintain comfortable indoor temperatures at lower energy costs. The whisper-quiet operation (<20 dBA) makes it suitable for living rooms, offices, classrooms, and commercial environments.
The Double Pack includes two Radboost PRO-5 fan units, a digital thermostat controller, temperature activation sensor, and UK mains power adapter. A connecting cable is also included for simultaneous operation of both fans. For extra-wide radiators, additional Radboost Extension accessories can be added to expand the airflow coverage.
