About Our Stirling Engine Stove Fans

Warpfive stove fans are small precision engineered Stirling engines, which are 100% mechanical and do not have any electric components which may stop working if overheated. Consequently they are extremely reliable and with care will last a lifetime. 

Every engine is precision engineered and hand built with durable materials like stainless steel, aluminium, brass and Borosilicate glass.  As a result they operate quietly – typically 36dB.   Additionally advanced materials (such as graphite) and low friction bearings ensure low maintenance. Furthermore heat flow is optimised with a silver themodynamic heat plate

Stirling engine stove fans have a high power output and low start up speed.  For this reason they move large volumes of warm air.  

Simply place your Stirling engine stove fan on top of your log burner or multi-fuel stove – operation is entirely free. In fact you will heat your room up much faster and you will save money by reducing the amount of fuel you use. 

Warpfive Fans are individually hand-crafted, assembled and tested in Great Britain and come with a  3 year manufacturer’s warranty.

Stirling Engine Reliability Test

Stirling engines are incredibly reliable.  The engines on the Warpfive test bed have exceeded 20 years of normal use (and still counting).  During this time period they’ve been oiled only three times with no other maintenance.

Quick Guide – How to Choose a Stove Fan

  • Firstly you need to establish your average stove top surface temperature. The heat on your stove surface will power your Stirling engine. Stirling engines are fueled by heat, so the more heat that enters the base of the engine – the greater the thermal transfer.   

  • Once you’ve established your average stove top temperature, examine the start up temperatures for each of the Warpfive Stove Fans. Also think about where you will use your stove fan.  For instance if it is a very large room, the Twinspeed will be the best choice.  However if your stove surface is Soapstone or if you feed your fire irregularly, the Glasshopper is an ideal choice.  Smaller spaces are best suited to the Sidewinder which has an overall height of 225mm (8.8 inches).  The Steelhead is a classic style which suits most applications. 

  • Finally make your choice and if you need any further assistance, please contact us.  We are here to help.

TIP:  If you don’t have a stove top thermometer – place a drop of water on the surface.  If it bubbles away instantly you’ll know it is above 100C (212F)

How a Stove Fan Works?

A stove fan is an innovative device that will help you to get maximum warmth from your stove.   When you use a Warpfive stove fan you will heat your room up to 40% faster and reduce your wood usage by up to 22%.

Without a stove fan the heat rises and warms the area directly above and nearby the stove. The area close to the stove is very warm while further away the room is insufficiently heated.

Using heat generated from your wood stove, a stove fan will circulate the warm air throughout your room.  Stirling engine stove fans are extremely powerful and able to move large volumes of air.  This saves on fuel and makes your home more comfortable.

Whilst designing Stirling engine stove fans, our engineers use FLIR cameras to optimise thermodynamic design.   In this footage you will notice the colour differential on the working Stirling engine. The base is bright yellow where it is hottest and then changes to purple / blue where it is coolest. The goal in Stirling engine design is to have the greatest thermal difference between the base and the top of the engine. This results in optimum performance and maximum power output.
