How it works

Powered from just heat!


The Vulcan stove fan does not require any electricity whatsoever! No batteries. No mains electricity. The Vulcan is self powered just from the heat of the stove. It utilizes a small, quiet Stirling cycle power plant built into the fan.

Stirling engine powered


The Stirling cycle power plant obtains its power from rapidly heating and cooling the same volume of air. When the air is heated, it expands, pushing a piston upward; when the same volume of air is rapidly cooled, it contracts, pulling the same piston downward, providing power. The same volume of air is heated and cooled very rapidly converting the heat energy to mechanical energy used to turn the fan blade. This expansion and contraction of air happens upto 7 times a second.

The hotter the faster


The Vulcan's fan speed increases relative to the temperature increase of its heat source. So, the hotter your stove, the faster the Vulcan will run and the higher the volume of air circulated. The Vulcan stove fan uses the latest and best technology, including borosilicate glass cylinder, graphite piston and ultra low friction demagnetised bearings to ensure it is completely maintenance free. You never have to oil it !
