About this product
If your radiators are working overtime but the heat keeps drifting up to the ceiling, the SmartAir Boost Fan Heater has a smarter approach. This clever little unit sits beneath your radiator and uses four energy-efficient axial fans to redirect all that rising warmth straight into your living space, so you feel the benefit sooner and your thermostat clicks off faster.
Designed for rooms up to 15 square metres, it runs on just 10 watts and weighs a portable 1.6kg, making it an economical way to improve heat distribution without cranking up the central heating. The freestanding design slots neatly under most radiators at 41cm wide, and the 1.8m cord gives you flexibility on placement. With two heat settings, thermostat control, and a built-in safety cut-out, it quietly gets on with the job of pushing warm air where you actually need it rather than letting it pool uselessly at ceiling height.

Effective radiator fan that improves room warmth and is good value. Some find it noisy and less powerful, with occasional fit and reliability issues.

A useful gadget to move the warm air.
The unit fits well on our old double radiator. Seems to circulate the warm air well. Does what I expected from it. A little on the noisy side when the fans are going full pelt.

Hi Kel.
SmartAir Boost Fan Heater:
Having checked the instructions, the Boost Fan will need to be in the ' ON' position on the switch. The fan will then automatically switch on/off when the desired heat has been reached.
Thank you for using Q&A.
Hello WeeAlzi,
I can advise the following for the SmartAir Boost Fan Heater:
Charging cable only, and no due to the heat of the battery being charged as well as the heat of the radiator could cause the battery to swell.
Thanks for using Q & A.
Hello Chell,

It is possible but it wouldn't be as secure as it would be on a double radiator.
