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.
Small Heat Powered Stove Fan
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.

The 2021 / 2022 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
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.

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
My Warpfive Sidewinder arrived promptly, safely and has exceeded all expectations from the moment it came out of its packaging! It truly is a thing of beauty and has been photographed and shared numerous times already. The workmanship is fantastic and it could quite easily be put on display but not only is it beautiful to look at it also does its job perfectly! Once my stove is up to temperature all that is required is a gentle flick in a clockwise direction and off it goes, silent and efficient. Gradually building speed until it’s a full revs and moving nicely warmed air around, not only the living room but around the whole house! Just open the doors and you can feel the warmth circulating around the whole house. It may be a thing of beauty when it’s still but when it’s in motion it transfixes your attention! The stroboscopic effect of the fine machined nuts holding the fan and drive wheels in place are somewhat hypnotic and very relaxing to watch. If you’ve not gathered, I love my Sidewinder and would not hesitate to recommend anyone to buy. You will not be disappointed! Thank you Warpfive.
This is my second purchase. The first bought as a gift for my son two years ago. My recent purchase is for a Christmas gift. The engines are like a piece of technological art – as well as a functioning air distributor. I wouldn’t hesitate in recommending them to other people.
Just a few words to say how impressed we are with our new Sidewinder fan. Upon opening our new fan and thermometer the quality of the items are immediately obvious. As an Engineer it was easy to really appreciate the workmanship that has gone into both items, they are simply sublime. I can only say don’t waste your money on one of the cheap electric stove fans or the highly inaccurate thermometers you see on the big box online sellers they are not even comparable. Operation wise initially we were worried that our stove wouldn’t get hot enough for it to work but those fears were soon put to rest on first lighting of the stove. Once up to around 100 degrees C give the blades a gentle nudge and it starts off really slowly as the stove temp rises it runs silently and speeds up so that it’s really noticeable in the room. On a personal note we went for the sidewinder as it looks more “mechanical “ than the standard fan and reminds me of belt driven record decks from the day absolutely gorgeous. The thermometer is a high quality item also and simply sits on the stove top. Great idea to use the rivets to show the peak operating range. Great piece of industrial design. Just a note for prospective buyers it is made from a solid billet of aluminium and so don’t expect it to be magnetic it simply sits on the stove top. But then again why would you want to stick it on the side of the stove when it’s looks like a piece of art? Don’t hesitate just buy it you know you want too
I like nice things. So when I decided I wanted a stove fan, Warpfive was the only way to go for me. It’s a fantastic piece of kit, really substantial and looks just the part. It’s always a talking point when people see it for the first time. I love my log burner and the stove fan just as much. If you’re considering one of these I urge you to do it; there will be no regrets. Customer service is also second to none, a real pleasure to deal with. Makes a nice change in this day and age. Thank you Warpfive!!
