Gas and wood burning stoves can provide a huge amount of heat for your home, and newer designs like pellet fuel stoves are tremendously efficient as well. So what could help a good idea work even better? The Ecofan helps distribute all that warmth around a room, powered only by the stove’s residual heat.
Intended for freestanding stoves and fireplace inserts (not regular fireplaces), the fan absorbs heat into its base when positioned directly on the stove. Through a process called the Seeback effect, the temperature differential causes tiny semiconductors within the case to generate an electrical current to spin the fan. (Click here for the manufacturer’s more technical description of the process).
The device is designed to operate on stove surfaces ranging from 150 to 650 degrees. The hotter the stove, the faster the fan moves; depending on the model, an Ecofan can move up to 150 cubic feet of air per minute. The manufacturer estimates that by distributing a stove’s heat more evenly, a homeowner could reduce wood consumption by 14%. Over the course of just one winter, that could add up to substantial money savings and a big reduction in emissions, while still enjoying a room that feels just as warm.
Manufactured in Canada by Caframo, there are three different models available: the Ecofan Original and Ecofan Airmax for wood stoves, and the Ecofan GS designed for the lower heat of gas stoves. Prices start around $79.
