About this deal

























- Redirect warm air from your radiators with our SmartAir Boost fan that prevents heat from instantly rising to the ceilings. It accelerates the warm air forward, boosting and improving the heat distribution, keeping the warmth at living height.
- This product is energy efficient with four axiel fans driving the radiator's heat through sealed air conducting funnels and into your room. The versatile design can be used corded or cordless. Run it off the mains power or charge the built-in power bank for up to thirteen continuous hours of cordless use.
- SmartAir Boost is a great way to heat your home. It fits on virtually any radiator, making it very versatile. It is engineered to be 41cm long, efficiently heating your whole room in no time so that your thermostat switches off quicker.
- Use either Manual mode for control or Automatic mode for maximum efficiency. With the flip of a switch you can choose between Manual and Automatic mode. In Automatic mode when your radiator’s surface heats to 33°C SmartAir Boost will spring into action, redirecting warm air into your room. When your radiator cools down to under 33°C the Boost will turn off so it’s never driving cold air into your room.
- Easy to transport to different rooms of your house depending on where you need it most. Move it from your home office in the day to the living room in the evening then to your bedroom at night. It doesn't require any installation, simply place it on top of your radiator and enjoy the added warmth. The Intelligent autoshut-off safety system means that if your radiator gets too hot and reaches 70°C then SmartAir Boost will turn itself off until your radiator cools to 65°C.
