Description
The Glasshopper Stove Fan is a Stirling engine built with a clear glass Borosilicate cylinder which shows the internal workings of the engine.
This highly versatile design allows it to work on most stove surfaces with the exception of diesel and catalytic stoves.
The Glasshopper Stove Fan will start working at 105° C (221° F) and its extra long run down time means it is highly suitable for use on Soapstone surfaces.
Named the Glasshopper for its ‘hopping’ internal cylinder, you will receive endless hours of enjoyment from viewing the mesmerizing moving parts.
When you use this Stirling engine stove fan you can reduce your wood usage by up to 22% and heat your room up to 40% faster.
See our Quick Guide on how to choose a stove fan.
Stirling Engine Design
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 12dB.
Advanced materials (such as graphite) and low friction bearings ensure low maintenance, plus heat flow is optimised with a silver thermodynamic heat plate.
Stirling engine stove fans have a high power output and low start up speed so they move large volumes of warm air.
Every engine is hand-crafted, assembled and tested in Great Britain.

As advertised and very nice. Wish it moved more air at lower temperatures.

Delivered at warp speed! Set it up really simply and lit the fire. When warm, gave the blade a little nudge and away it went. Great. Not much evidence of a draft from it and wonder whether the blades are as aerodynamic as they could be … but it looks great.
