Valiant Fun Valiant Radiator Fan | Rechargeable Heat Booster | For Single & Double Radiators

Make better use of the warmth produced by your central heating with the upgraded Valiant Radiator Fan, a rechargeable radiator booster designed to circulate heated air more effectively around your room. Its improved triple-fan ventilation system draws heat from the radiator and redirects warm air further into your living space, helping rooms warm more quickly and evenly rather than allowing valuable heat to simply rise above the radiator. Powered by a 5100mAh rechargeable battery, the Valiant radiator booster provides approximately 6 to 16 hours of cordless operation, depending on the selected fan speed. The supplied USB-C cable makes recharging straightforward, with a 5 V/2 A USB adapter recommended for faster charging. The fan can even operate while charging, although fan speed may be reduced. Choose between three manual fan speeds or let the intelligent automatic mode manage airflow according to radiator temperature. In Auto mode, the fan remains in standby below 28°C, operates at speed 1 between 28°C and 40°C, speed 2 between 41°C and 46°C, and speed 3 above 46°C. Once in standby, it automatically wakes when the detected temperature reaches 33°C. The redesigned top-facing digital display and controls make operation easy when the fan is positioned on top of your radiator. View real-time temperature, selected fan speed and remaining battery level at a glance, while the adjustable timer offers 2, 4, 6, 8, 10 or 12-hour settings. Installation is equally straightforward. Strong magnetic attachment provides secure placement on suitable steel radiators, while two mounting clips are supplied for secure installation on compatible single radiators. For optimum airflow, Valiant recommends positioning the fan on a flat-topped radiator with a grille. Measuring just 41.3 x 10.7 x 8 cm and weighing approximately 700 g, the sleek, sturdy design is compact enough to sit discreetly on your radiator. The improved system operates at a stated noise level of less than 38 ±5 dB, making it suitable for living rooms, bedrooms and home offices. An integrated high-temperature alarm provides additional reassurance, sounding if the detected temperature exceeds 70°C. Compact, rechargeable and intelligently controlled, the Valiant Radiator Fan is a practical way to improve warm air circulation and get more from your existing home heating.
