How do fans on wood stoves work?
Beside this, how does an Ecofan generate electricity?
Ecofan – Generates its own electricity. These fans generate their own electricity using the heat from a stove. The fan acts like a large heat sink, drawing heat from the stove up through the aluminium base. Half way up the base is a peltier cooler.
Also asked, are wood stove Fans effective?
Yes, they are effective as they help the home get warmer quicker and do not waste any electricity while doing so. They are also noiseless, so you do not have to worry about the fan being too loud. They can also ensure warmth 20% faster than having no stove fan.
Peltier devices are designed to move a given amount of heat when the hot side of the device is at a given temperatures and the cold side is at a given temperature. The cold side for the refrigerator will be around 2.7C for perishables. The hot side would be room temperature so about 21C.
