VonHaus 4 Blade Stove FanIncrease the efficiency of your stove oven or wood/ log burner with the VonHaus 4 Blade Fan.There’s no need to turn up the heating or switch on an electric radiator to heat your home up - this manual fan creates its own energy and is powered entirely by heat. This means no need to constantly fork out for expensive batteries or worry about running up a sky-high electricity bill.How It WorksThe science behind this fan is simple but highly effective. The fan comes fitted with a thermoelectric module which acts as generator to power the fan’s motor – this starts up once the module detects a minimum temperature of 60°C, at which point it begins circulating warm air around the room.Automatic Regulating HeatThanks to a rapid fan speed of 1200rpm max., which circulates between 150 - 190 CFM (cubic feet air/ minute) you’ll feel the benefits in no time at all. Self-regulating design automatically adjusts depending on the temperature in the room – speeding up as the temperature rises and slowing down as it begins to drop.Plus, the temperature gauge included allows you to monitor and optimise stove fan efficiency to avoid damage by overheating (max. operating temperature: 350°C)Premium Black AluminiumPremium black aluminium construction features four large blades for maximum airflow, plus a carry handle for hassle-free portability.Extremely quiet – won’t disturb the household when in use.No installation required.Suitable for use with most styles of freestanding stoves and wood/ log burners.Simply position on top of your stove as far away from the flue pipe as possible, and do not operate in conditions exceeding the maximum working temperature of 300°C – incorrect use of the stove fan could damage the product.SpecificationAir Flow: 150 – 190 CFMWorking Temperature: 50 - 350°CBlade Size: 8 X 7.5cmSKU: 14-079
