Description
The Twinspeed Stove Fan is the best fan for large rooms because it has an exceptionally high air output – in excess of 442 CFM (cubic feet per minute) of air.
The Twinspeed Stove Fan will work on any medium to high heat wood stove or multi-fuel stove surface and has a start-up temperature of 120° C (248° F).
Named the Twinspeed for its twin piston cylinders, it provides high performance with maximum airflow.
When you use a Twinspeed Stove Fan you can reduce your wood usage by up to 22% and heat your room up to 40% faster.
If you are the owner of a diesel or catalytic stove, please read advice on the FAQs page.

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.

Fan too noisy and doesn’t push warm air from stove. I returned but told I would not receive full refund due to discolouration of the metal from exposure to heat. This would polish out but deducted £75 being genuine I returned the item and did not
Polish it out before hand. I’ve asked for the base to be returned to me if I’m forced into purchasing it. No use apparently because it cannot be resold.
Overall conclusion, expensive ornament, I would not personally purchase this item again, nor anything similar.
