SmartAir BOOST Radiator Fan

The SmartAir BOOST is the original. 

Give your heating a boost and save money year after year! Feel warmer quicker with the original, energy-saving SmartAir BOOST. The patent-pending, portable, heat circulator that re-directs the heat from your radiator into the room where you are, rather than into the walls or out the window!

It’s the patent-pending, compact, and portable multi-fan heat circulator designed to reduce energy wastage and save you money. This energy-efficient system improves the circulation of warm air, heating your living space faster and more efficiently. 

SmartAir BOOST is designed to improve heat circulation to speed up room warm-up times so your thermostat switches your heating off quicker, saving you money.  

• Cut your heating bills: circulate heat at living height, not ceiling height so your thermostat switches off quicker and saves you money.
• Save money year after year.
• Redirect warm air from your radiators: rather than letting all your heat rise to slowly heat your room from the ceiling down, SmartAir Boost redirects rising heat from the radiator and accelerates it forward, boosting and improving the heat distribution more effectively.  
• Patent-pending engineered design: four energy-efficient, axiel fans drive your radiator’s heat through sealed air-conducting funnels into your room where you want and need it. 
• Use either Manual mode for control or Automatic mode for maximum efficiency: easily change between the two modes with the flip of a switch.
• Use either Manual mode for control or Automatic mode for maximum efficiency: easily change between the two modes with the flip of a switch.
