Stirling Engine – Vulcan Stove Fans £149.99
Heat from the stove body is used to power a two piston Stirling engine. The engine directly drives a large powerful fan.
This beautiful Stove Fan will sit on top of your wood or coal stove and gently and efficiently circulate warm air around the room. Increase efficiency, don’t run the stove blazing hot just to warm the cooler parts of your room.
The Stirling Engine in this device is remarkably efficient, and will operate on a stove as cool as 150°C and as hot as 450°C. The fan will spin at about 200rpm at 200°C, increasing to about 350rpm at 450°C.

Caframo Ecofan 812 Airmax & 810 UltrAir Wood-Stove Fan £149.99
The Caframo Ecofan is a heat-powered fan designed to circulate the warm air created by a wood or coal stove. Operating over a wide range of stove top temperatures; between 65°C and 345°C. These fans do not use batteries or mains power, instead they generate electricity from heat absorbed from the stove
body. A heat differential across the fan generates electricity via a Peltier Element.
Left – Ecofan AirMax 812
Right – Ecofan 810 UltrAir
Warm air is circulated directly into the living area rather than having most of the stoves heat rise immediately to the ceiling, thereby increasing the heating efficiency of your stove.
Unique Blade Design:
The unique anodised gold or nickel coloured blade has been specifically designed to deliver a very broad cross section of gentle air movement instead of a small cone of concentrated air.
Ecofans start automatically and adjust speed with the stove’s temperature. As the stove heats up the Ecofan runs faster to move more air into the room. As the stove burns down and cools, the Ecofan automatically slows down and stops.
