Thermoelectric Heat Powered Stove Fans
There are two ways in which heat powered stove fans work. The first is through thermoelectric energy conversion. This is a complicated name for a very simple process where the heat that the stove is generating is not only used to heat your room, but it is also taken in by the fan and converted into electricity which powers the fan. This is a great way to generate power to run the fan because you are already generating heat with the stove.
The other method that can power a stove fan is a method in which alternating hot and cold temperatures produce energy and that energy is then used to power the fan. This method is a little more complex than the thermoelectric process, but a stove fan that is powered this way needs to maintain a base contact with some heat source that is at least 85 degrees. Then top of the fan remains cool and draws in cooler air from behind. The rotation of the blade works in conjunction with the cold air and the heat source to produce a reaction that powers the fan.
Here's how the Stirling engine works.
Benefits of the Heat Powered Stove Fan
There are a number of benefits to having a heat powered log burner fan for your wood-burning stove. The main benefit was previously discussed and is probably the biggest reason that people choose to get one – the fact that it allows you to use the stove’s own heat that it is already generating to power the fan, circulating the warmth throughout your entire room and reducing the cold spots and hot spots that you get when a stove is used by itself. So, the benefits of the stove fan are that it makes using a wood burning stove practical and saves you money on electricity by allowing you to power the fan through the stove’s own heat generation. Finally, the fan improves the stove’s reach, which means that you may not even have to use your electric or gas heat.

Installation and Cost of a Heat Powered Stove Fan
Getting a heat powered stove fan is less than you think, and the cost of having one is truly an investment rather than a cost, because you’ll be saving money on your electricity bill for years to come. Installation isn’t difficult either and there really is no reason not to get one. If you have a wood burning stove and you’d like to improve the efficiency and heat up your home better, then you should definitely look into a heat powered stove fan.
