A Heat Powered Stove Fan is a device that sits on top of your stove and uses the heat from the fire to power a fan that blows the warm air around the room. This way, you can get the most out of your stove and enjoy a more comfortable and pleasant environment. Some heat powered stove fans are noisy, slow or inefficient. This is why you need the Valiant Whirlwind Stove Fan. This fan is a new and innovative product that offers up to 70 per cent more air flow than competitor products. It has a unique design that creates a whirlwind effect that spreads the warm air faster and farther. And it has zero running costs, as it is totally heat powered, meaning there is no need for batteries or mains connection. This fan operates virtually silently so you can enjoy your fire without any annoying noise and features an inbuilt protection system that prevents overheating, as well as a starting temperature of just 45 Degrees Centigrade and can operate up to a maximum temperature of 340 Degrees Centigrade. The fan is designed and engineered in the UK using premium long lasting components featuring a hard wearing black anodised finish to complement your stove. The Valiant Moisture Meter is a handy accessory to your fireplace and ensures you get the best burn from your fuel. Our newest model not only has a backlight screen to illuminate the reading but the built in colour change technology indicates the moisture level of the firewood. Its an essential tool for any fireplace owner. Fuel quality is the single most important aspect of making a successful fire. To burn effectively the moisture content of firewood needs to be less than 20 per cent, whether its being used in an open fire or a stove. Freshly felled timber can have a moisture content of between 30 per cent and 60 per cent, which when burnt can cause dangerous creosote build up in chimneys. Using a moisture meter is a great way to check whether your wood will give you a safe and efficient burn, or if it needs further seasoning. The screen will glow green if your fuel contains less than 20 per cent moisture, indicating that its ready to go. Finally, the set includes a green magnetic thermometer which monitors your stove temperature to optimise performance and protect your stove from overheating. It clearly displays the temperature of your stove, enabling you to maintain a safe and efficient operating temperature and reduce fuel consumption. The thermometer attaches with a strong magnet and is best used to monitor stove or flue pipe temperature and performance. By using this you will reduce or optimise fuel consumption and optimise the stove temperature to reduce chimney deposits aswell as decreasing the risk of overheating damage.
