SmartFan | SmartFan Mini - Temperature Range 65°C - 330°C

The SmartFan is a self-powered, clean, silent and efficient device that greatly improves heat circulation from your solid fuel burning stove. The device is powered by a thermoelectric generation module (TEM) which uses the hot surface of the stove to generate an electric current to propel two fan blades. Heat, instead of rising immediately to the ceiling, is propelled directly into the living space and provides an increased level of comfort and greater fuel efficiency.

The device works on a simple principle; the hotter the bottom and the colder the top, the more electricity is generated. In order to maximise its output, the unique design incorporates an axial fan on the top section which keeps this part cooler and projects hot air into the living space. By utilising this fan on the top section and by incorporating an aerodynamically designed front fan blade, the SmartFan can move air up to a rate of 360 Cubic Meter per hour (200 Cubic Feet per minute).

SmartFan LT | SmartFan Mini LT - Temperature Range 60°C - 190°C

The Low Temperature SmartFan is a self-powered, energy saving, silent and efficient stove fan, which was designed for stoves with an external surface temperature of maximum 190°C. The device is working on the same principle like SmartFan; the hotter the bottom and the colder the top, the more electricity is generated.

How it works

When an electrical conductor has two different temperatures applied to it, the conductor allows for the transfer of heat to the hotter side. In this process of heat transfer, the thermal energy also moves charge carriers within the conductors. This is the process (also known as the Seedbeck effect) that generates the electrical current in the SmartFan. However, in this process, the charge in each individual pellet is very small. To increase the output voltage, it is necessary to use complimentary conductor pellets (P and N). Applying two dissimilar conductors, one positively doped (P) and one negatively doped (N) allows for the electrical current to flow block to block. These blocks can be considered to be in series, meaning that each block adds a certain amount of electrical current. It can then be considered that the output voltage s equal to the charge per block multiplied by the number of blocks.

How it works

By using two fans, the SmartFan has been designed to maximise this effect. The main fan is used to propel hot air into the living area, while the auxiliary (side) fan is used to keep the top section as cool as possible while also circulating geated air into the living area. this has resulted in efficient, cost effective and environmentlly friendly product and means that, in effect, the higher the temperature of the stove or hot plate, the faster the blades on the SmartFan will turn

Making the most of a solid fuel or wood burning stove

Heated currents of air naturally ascend. Due to this, a solid fuel stove generally creates a small envelope of heat in its immediate surrounding area. This effectively means that to heat the living area of a room, it is necessary to use a quantity of solid fuel that is relative to its lenght, width and height. The SmartFan effectively provides direction for this heated air and allows for a greater fuel economies than a solid fuel stove acting alone. the SmartFan, when placed on top of a lighted stove or hot plate automatically starts and creats two gentle convection currents. As a direct result, warm air is, without creating a draught, propelled into the living area and the room heats up much more quickly. The greater the heat output of the appliance, the greater the speed of the fan blades and consequently the greater the circulation of warm air. Conversely, as the surface temperature cools down, so too does the speed of the blades and the warm air circulation. Just as it starts automatically, it also stops automatically and in both cases, gradually. The motor themselves are very low torque, which allows the fan blades to be easily stopped and do not present a safety hazard.
