This innovative fan increases the output of a wood stove by circulating the warm air it generates directly into your living space. By preventing heat from escaping directly into the roof, the amount of fuel required to achieve a room temperature is reduced, giving increased comfort at lower running costs. It also reduces the impact of burning solid fuel on the environment, especially as it requires no power itself.
How it works
In 1821 Thomas John Seebeck discovered the thermoelectric effect, (now commonly known as the Seebeck effect). He discovered that an electrical pulse is generated when two dissimilar metals at different temperatures meet.
The thermoelectric module in this fan harnesses the technology that has developed from this law. As the base of the fan heats up, the metal in the bottom of the unit warms along with a heat sensitive spring. Meanwhile, the temperature of the different metal in the unit’s top surface is kept down by the fans cooling fins.
When the heat sensitive spring reaches a sufficient temperature it tilts the unit forward, bringing the two layers of metal together. This creates the electrical pulse that turns the blade on the fan.
The greater the differential in temperature of the metals, the greater the electrical output, meaning that your fan turns faster the more the stove (and therefore the base of the fan) heats up.
The unique anodized blades on this stove fan have been designed to deliver a very broad thermal current as opposed to a small cone of concentrated air. As the blades are manufactured from anodised aluminium they will not rust or corrode.
As it starts automatically and adjusts speed according to the stoves temperature, the fan works harder as your stove does. It runs faster to move more air into the room as the stove heats up and automatically slows down and stops as the stove cools.
Placement of the fan is critical to optimum performance. It should be positioned at the rear of the stove. This allows heat to be absorbed into the base and upwards, whilst ensuring that the cooling fins can draw cold air from above.
It is this combination of hot and cold on the thermo conductor that triggers the reaction required to generate the electricity that rotates the fan. The fan should not be placed at the front of the stove or near the stovepipe as there is insufficient cold air in these areas.
The stove fan is designed for usage on freestanding stoves with a normal surface temperature of between 205 degrees and 345 degrees Celsius. Temperatures above this range may damage the fan and the electricity generating units and invalidate your warranty. Good stove safety practice includes the use of a stove thermometer.
Never handle the base of the stove fan when hot. To move or carry the fan, always use the extendable handle. Never set the stove fan down on an unprotected surface when hot.
