Radboost PRO-5 Radiator Booster Fan – Magnetic Fit Radiator Fan with Auto Temperature Sensor – Heats Rooms 2x Faster, Save up to 30% – Single Pack | Double Pack | Extension Set
Your radiator is wasting heat. This fixes it.
Radiators lose much of their warmth to the wall behind them and the ceiling above while the room stays chilly. The Radboost PRO-5's five-fan bar sits discreetly underneath and circulates that trapped warm air out into the room where you actually feel it. The room heats faster, your boiler works less, and you can turn the thermostat down without losing comfort.
Key Features:
- Heats rooms up to twice as fast – Five whisper-quiet fans per unit circulate warm air throughout the room
- Save up to 30% on heating costs – Lower your thermostat and boiler temperature while staying just as warm
- Fully automatic – The built-in temperature sensor switches the fans on when your radiator warms up and off when it cools
- Near-silent operation – Under 20dB, quieter than a whisper; fine for bedrooms and living rooms
- Fits all types of standard radiator – Built-in magnets attach in minutes to single and double panel, column and most non-standard radiators, with multiple installation methods in the included manual
- Adjustable thermostat controller – Fine-tune activation for maximum comfort
- Low running cost – Sips power via the included USB-C UK mains adapter
- Expandable system – Start with a single or double pack and add Extension Sets for wider radiators
Which pack do I need?
