The SmartAir Boost XL, a portable multi-fan heat circulator priced at £69.99 on the Yimbly website, is designed to improve heat distribution around the home, helping rooms warm up faster and potentially reducing energy waste.
The patent-pending device circulates warm air at living height rather than allowing it to rise towards the ceiling. By distributing heat more effectively, it can help a thermostat reach its target temperature sooner and switch heating off earlier.
How the SmartAir Boost XL works
Its axial fans channel warm air through specially designed air-conducting funnels. Users can choose between manual and automatic modes at the flick of a switch. The built-in heat sensor activates the fans when the radiator reaches 33°C, directing warm air into the room. When the radiator cools below 33°C, the fans switch off to avoid circulating cold air.
The device is described as energy-efficient, with running costs claimed to be less than half a penny per hour (running costs may vary depending on electricity tariff). It weighs 2.4kg and measures 81cm x 10.6cm x 11.5cm.
Shopper reviews and other deals
One shopper said: "Wish these were on the market years ago, could have saved a fortune on energy bills. Rooms heat up much quicker, fabulous product."
Another review read: "Fantastic product, has made a cold room warm again. Recommended for anyone looking to radiate heat from a lukewarm radiator."
A third said: "I've had one of these for a couple of years, it's a excellent product, it does exactly as described. I'm more than satisfied with this item."
A fourth added: "This is amazing, I have my sofa against the radiator in my lounge Which blocks out most of the heat. The fan now directs the heat over the top of my sofa and I have a warm room again. Wish I had bought one a long time ago."
At the time of writing, the only negative review reflects a delivery issue. The SmartAir Boost XL is available for £69.99 on the Yimbly website.
