The Sidewinder is a small heat powered stove fan which operates across a broad range of temperatures.
It’ll work on any medium to hot stove surface and starts operating at 110° C (230° F).
Named the Sidewinder for its dual pulley and belt operating mechanism – it has an intriguing Stirling engine design which is captivating to watch plus highly functional.
The stepped up pulley ratio increases the Sidewinder’s RPM and enables it to move an impressive 320 CFM (cubic feet per minute) of air.
When you use a Sidewinder stove fan you can reduce your wood usage by up to 22% and heat your room up to 40% faster.

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. Find out more here
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 28dB.
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.
The 2021/22 Sidewinder model includes the following design modifications –
- Solid stainless steel base with no uprights for improved thermodynamic performance
- Profiled fan blade for enhanced air circulation
- Light-weight composite crank for higher RMP
- Dust cover included

Beautifully finished fan, prompt delivery and a great product.
Looks fantastic and works perfectly, a great talking point with visitors.
The fan is whirring around as I write this review and I have to say it’s pretty impressive .
The well packaged fan arrived safe and sound together with tools and instructions etc.
The stove fan is certainly very well made and looks fabulous on the stove top.
Definitely deserves 5 stars for looks alone .Thankyou Warpfive .
I recently purchased my second Sidewinder - so the woodburner looks more symetrical!
Fabulous looking and efficient fan, very quiet too. Delivery was fast and the service from Warp Five was excellent especially in regard to a spare belt for my older fan as it differs slightly from the current Sidewinder iteration. Thank you very much.
Now my stove is warmer than ever but looks even more "cool" than it did before!
Despite the name, the product shipped at what must have been warp nine. Arrived in the US after 2 days perfectly intact. I'm impressed with the quality of design and how well it functions. I am a bit wary of the plastic dust shield- it seems to hold up after a typical use, but given how hard it is to accurately measure the temperature of clear plastic, and the possible mess it would make if it melts, I probably won't be using it during operation. It seems to move a fair amount of air, looks stylish, and is nigh silent. Being a nerd, I would have appreciated an info pamphlet explaining the mechanism, but otherwise very solid product.
I ordered the sidewinder after marvelling at how awesome and cool it looked. At that moment it didn’t matter if it worked or not! But it does work and that makes the happy feeling in my belly from earlier even better and bigger! It’s one of those purchases that just feels worth it. Everyone should have one, even if you don’t have a stove you could put it in your frying pan to push the magical smell of bacon around the downstairs of your house. I have long hair and I can say with honesty that this fan is a better purchase than my hair brush!
The stove fan is great thanks. It’s an intriguing and attractive engineering curiosity and silently, efficiently, pushes heat into the room. I’m recommending them to all my neighbours who have wood stoves
About two years ago, we purchased a Sidewinder for our wood burning stove (due to limited space), we have been extremely delighted with it and it has been 100% reliable. They are not the cheapest stove fans, but of those we tried, there is no comparison, this is a product that you absolutely get what you pay for. To be honest, we don’t know which is the best feature – the tremendous engineering, the silent operation, the simple beauty of it, the efficiency or … its discussion attraction with the interest of all who visit and see it – whether the stove is lit and the fan is working or whether it’s just motionless on top of the unlit stove! Oh, and a word about Warpfive’s customer service… it is excellent – we have experienced fast and clear answers to all questions. Ordering is very easy, delivery is fast and secure by reliable couriers. We have had no hesitation in now purchasing a Steelhead to join our soon to be installed stove cooker in another room in our home and we are expectant of the same superlative features! Thank you Warpfive
