Sam Jones, a reviewer, has tested the SmartAir Boost XL Radiator Fan (£69.99) and found it significantly improves how quickly a room warms up. The fan directs warm air from the radiator into the room rather than letting it rise to the ceiling, reducing wasted energy and potentially cutting heating bills.
Jones previously tried SpeedComfort radiator fans and was impressed, but considers the SmartAir fan superior due to its sloped design that fits even near windowsills. The fan operates automatically, turning on when the radiator temperature exceeds 33°C and off when it drops below, and can run cordlessly for up to 14 hours on a full charge.
The main drawback is noise; the highest setting is too loud for some, but the low setting is effective and less noticeable in busy rooms. Jones notes that the fan costs less than half a penny per hour to run, making it an economical choice for those looking to reduce energy costs.
