Kontax Stirling Engines designs and manufactures a wide range of low temperature and high temperature differential Stirling engines, thermo acoustic engines and wood burning stove fans. All are designed, manufactured and assembled in our purpose built workshop in the beautiful Thames Valley in southeast England.

Our outstanding reputation has been built on high quality and attention to detail. Customers range from individual enthusiasts all the way up to corporate multi-nationals. If you want a unique gift for a friend or relative or need a high quality corporate promotional item then you have come to the right place.

We also offer laser engraving.

We also manufacture the Vulcan stove fan and Mini Vulcan stove fan. If you have a wood burning stove you can put this Stirling engine powered fan on it and it will circulate the warm air from the stove around the room using only the heat from the stove.
