These ingenious stovetop fans are completely silent and cost nothing to operate. Their operation is based on a phenomenon known as the Seebeck effect, using thermocouple technology to generate an electrical current by exploiting the temperature difference between the stovetop and the ambient air.

The fan speed on each varies with the temperature difference (greater difference, greater speed), quietly moving warm air from the stovetop. Made largely from anodized aluminum, they are an efficient way to disperse heat.

Intended for wood-burning stoves, the medium-size model can produce up to 125 cfm of air movement, stands 9" tall, has an 8" diameter brass blade, and operates on surface temperatures between 212° and 650°F (100° to 345°C); the large model can produce up to 175 cfm of air movement, stands 10" tall, has a 9" diameter brass blade, and operates on surface temperatures between 185° and 650°F (85° to 345°C).

The Ecofan GS is specifically for gas stoves. It has a base designed for greater heat conduction and two thermoelectric modules (the others have only one) to create enough electricity to run the motor. 6 1/2" tall, it has a 9" diameter brass blade. Operates on surface temperatures between 167° and 392°F (75° to 200°C) and circulates up to 140 cfm. Cannot be used on wood stoves (the high heat causes an overload switch to trip).

These make great gifts for anyone with a wood or gas stove.

Made in Canada.
