Our innovative Premium 4 Stove Fan is a uniquely engineered design. It's blades generate up to 70% more airflow than competitor products, giving you maximum benefit, whilst standing at just 199mm tall. The Premium 4 fan operates at a low starting temperature (approx. 50C), which means your living space will be toasty in no time. Simply place the Premium 4 onto the top of your wood-burning stove and feel the warm air distribute further into your room. The Premium 4 Fan requires no batteries or external power. The heat of the stove top is conducted though the base of the fan and converted to electricity which powers the fan motor. The fan automatically slows and stops as the heat from the stove reduces. With a durable, hard wearing black anodised finish, the 4 Blade Stove Fan not only looks the part but is designed for everyday use and long lasting performance. All Valiant heat powered stove fans are ideal for use on wood burning stoves in homes, narrowboats, or mobile homes, and can also be used on kitchen ranges and hobs.
