This article is written to give information on how to compare and choose a stove fan. In addition it will help you to establish which stove fan will best suit your requirements.

Frequently a room becomes overly warm close to the wood burner, but the the remainder of the room is cooler. A stove fan will assist in spreading the heat evenly and efficiently around the room. Consequently this will help to increase your comfort levels and save on your heating fuel.


In the image above, you can see how the heat rises directly above the stove without a stove fan - leaving the rest of the room unheated.


When you use a stove fan, the heat is circulated throughout the room - saving on heating fuel and making it more comfortable.

Different types of stove fans are available but if you want a stove fan that lasts a lifetime and compliments your home, you should consider a Stirling engine stove fan.

Stirling engine’s are fascinating eco-friendly devices that use only heat to work. Because they are very powerful, they move a great volume of air. They do not have any electrical components which will burn out so they are extremely reliable, as well as attractive.

A Stirling engine works by moving a sealed volume of air from the hot bottom plate to the cool top plate of the engine. As the air moves from the cool plate to the hot plate it is rapidly heated, it expands and pushes the piston up. As the air is moved from the hot plate to the cool plate it cools rapidly and contracts – this creates a vacuum which pulls the piston down. This same volume of air is rapidly heated and cooled many times per second. As the piston is connected to a crank shaft it causes the crank to rotate, and this produces the mechanical power to rotate the fan blades.

A Stirling engine stove fan will improve the heat circulation within your home, save heating fuel and provide a more comfortable living environment. It will quietly circulate the heat generated by your wood burner or multi-fuel stove throughout your home. Therefore you will benefit from increased heating efficiency, improved comfort and a reduction in your operating costs. A Stirling engine stove fan operates quietly and is totally free – simply add heat.

Stirling engines take time to build and enormous precision is required, for this reason there are very few manufacturers.

Warpfive Stove Fans manufacture and produce a variety of hand-built Stirling engines to suit different operating requirements. Here you can read about, compare and choose a stove fan that is ideal for your purposes.

First of all you need to determine which engine will work most efficiently in your environment, this is easily done by determining your average stove top temperature.
