Get cosy with this SmartAir Boost Fan Heater. Rather than letting heat rise from your radiators to the ceiling, it redirects warm air to the areas you actually use. Automatic mode springs into action when your radiator's surface heats to 33°C and powers down when it cools to under 33°C. Or just use the Manual mode to warm a chilly room. Good to know - It fits almost any type of radiator so you'll be able to use it in most rooms- It takes care of itself by automatically shutting off as soon as it reaches 70°C till it cools to 65°C - It'll only drive warm air into your room thanks to its intelligent heat sensor - With up to 14 hours of battery life, it'll last you for the entire night - Its lightweight and portable so you can easily move it from room to room
