​Reduce your wood usage by up to 19% and heat your room up to 38% faster​

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.

A stove fan assists in circulating warm air throughout the room, this saves on fuel and makes your home more comfortable. The Stirling engine powered Glasshopper is so efficient that a 240° C (464° F) fire temperature will provide sufficient power to move air in excess of 5 metres (16.4 feet).

The Glasshopper Stove Fan is designed to be used with cooler fires that are fed irregularly or on top of cooler stove surfaces such as Soapstone. This unique stove fan has a clear Borosilicate glass cylinder which enables a view of the rhythmic displacer movement that produces the energy to spin the fan. This intriguing device can be placed on a Soapstone surface or on a cooler section of any wood stove or multi-fuel stove or other heat source that operates between 80° C and 300° C (176° F and 572° F). The Glasshopper is a small precision engineered Stirling engine, which is 100% mechanical and does not have any electric components which may stop working if overheated. Stirling engines require great precision to build but reward with exceptional reliability, high power output and longevity. This unique item is hand-crafted, assembled and tested in Great Britain.
