Helps to distribute the heat generated by your stove more evenly and quickly around the room meaning you can enjoy a warmer and more comfortable environment without waiting too long. Reduces the hot and cold spots in your room so you can avoid overheating or underheating certain areas of your room and have a more consistent temperature throughout. Minimises the stove heat requirement and therefore the fuel cost allowing you to save money and energy by using less fuel to keep your stove running and also reduce the amount of CO2 emissions into the environment. The unique design of the Valiant Whirlwind fan offers up to 70% more air flow than competitor products with zero running costs as the fan is totally heat powered meaning there is no requirement for batteries or mains connection. The fan operates virtually silently and features an inbuilt protection system that prevents overheating as well as a starting temperature of just 45°C and can operate up to a maximum temperature of 340°C (Optimum operating temperature 80-250°C).
