Are heat powered stove fans worth it?

Quick answer: Wood stove fans are worth it, but only for smaller rooms. They will help distribute the hot air a little but are more of a toy and nice to look at as a design item. If you seriously have to distribute heat in your home, you should use an electric floor fan.

How do stove fans generate electricity?

The Peltier device generates electricity by having one side hot and the other side cooler (known as a ‘thermal difference’). This temperature difference creates a ‘potential difference’ (a voltage) in the circuit. This voltage powers the motor, which in turn drives the fan.

Are stove fans a gimmick?

Designed to rapidly improve the circulation of heat from the stove, and therefore reduce hot and cold spots throughout the house, stove fans aim to not only improve comfort but also improve the stove’s efficiency and reach.

How much air does a stove fan move?

Fan Size and Quality A range hood fan should move a minimum of 100 CFM of air for every 12 inches of stove width. This means that if you have a stove that is 30 inches wide then you need a range hood with a fan that rotates at least 250 CFM of air.

What is a heat powered fan called?

Stove fans are small fans that are usually set on top of a wood-burning stove, although they can be put on top of anything warm, like an oven. A stove will slowly radiate heat into the surrounding room, but it can take a long time for this to warm up a room.

What temperature do stove fans work?

Wood stove fans will typically only be able to work within a certain temperature range, and the hotter the stove is running the more air can typically be distributed by the fan. For example, our stove fans are designed to work within the 175-650 F (80-345 C) temperature range.

Where should you put your stove fan?

The stove fan is effectively an engine that uses the heat differential between the base of the unit and the top of the fan to drive the motor which in turn, turns the blades. Place your fan on one side at the back edge of the stove. In this position, it will draw cooler air from the back of the stove area.
