Overview
- The SmartAir BOOST XL is sold on Yimbly for £69.99, and Yimbly is owned by Reach PLC, which publishes the outlets covering the product.
- The brand markets the fan as boosting warm‑air circulation to heat rooms faster and as costing less than a penny per hour to run, though these claims come from listings rather than independent testing.
- Articles report automatic start/stop tied to radiator surface temperature, citing a 33°C activation and a 65°C cool‑down cutoff, with the differing figures not reconciled.
- Customer reviews quoted from Yimbly and Amazon often praise quicker room warming and portability, while several note noticeable fan noise.
- Features listed include corded or cordless use, a 2.4kg weight, and an LED display showing fan speed, battery level and radiator temperature, with alternative heaters from Amazon and Debenhams also flagged.
