Well engineered
Worth the wait for its availability. Throws out the heat from our alcove silently and warms the room well. Looks good and it’s a good conversation piece whether the stove is in use or not. I like the clear chamber so you can see the piston working – Alan UK

Excellent Product And Services
‘Great design and engineering! It works very well on my soapstone stove. Quick and polite response, and prompt delivery increases trust to the product. The logo of “Great Britain” on the top plate is shining!’ – Yoshiki Japan

Arrived after their long journey in excellent condition
‘Recieved my twinspeed and glasshopper stove fans last week. Arrived after their long journey in excellent condition, nice to see the packaging is recycled/recyclable materials.
The engineering and construction of these fans is second to none. Work like a dream and very quiet! Thoroughly enjoy watching them in action, almost mesmerizing.
????? from me.’ – Grant New Zealand

The fire makes more noise than the fan
‘I ordered this unit a little late for much use in the winter season here in Colorado, USA. Ordering was easy, and the item arrived faster than other packages from within the US. I’ve only used the unit a bit more than a dozen times, but it has worked flawlessly and is extremely quiet, the fire makes more noise than the fan. It looks to be well made and I expect to be using it for many seasons.
5 stars.’ – David USA

I have long hair and I can say with honesty that this fan is a better purchase than my hair brush!
‘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!’ – Phil United Kingdom

An improvement with warm air circulation
‘We’re extremely happy with our Warpfive wood stove fan. Having used a stovetop fan for many years and it needed to be replaced, we can certainly see an improvement with warm
air circulation now with our new fan. And the clever engineering is fascinating.’ – Ashley & Jenny United Kingdom

Delivered at warp speed
‘Delivered at warp speed! Set it up really simply and lit the fire. When warm, gave the blade a little nudge and away it went. Great. Not much evidence of a draft from it and wonder whether the blades are as aerodynamic as they could be … but it looks great.’ – Peter UK

Well done WarpFive and five stars from me
‘I am all for giving praise where it is due. The service I have received from ‘WarpFive’ has been exemplary from start to finish. Prior to ordering, I emailed WarpFive with a couple of questions regarding the Steelhead stove fan and they replied within minutes. I then went ahead and ordered the ‘Steelhead Stirling Engine Stove Fan’. From the moment I unpacked the fan it was obvious that it had been very well engineered and assembled. With Very minimal assembly on my part, I soon had it sitting pride of place on my wood stove. Within only a few minutes it started turning and as promised the fan ran smoothly and quietly. As well as being very efficient in circulating warm air, it is also intriguing to watch. All I can say is, Well done WarpFive and five stars from me.’ – Paul UK

Silently, efficiently, pushes heat into the room
‘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.’ – Ian UK

I absolutely love this little “ fan “
I absolutely love this little “ fan “. It is currently spreading harmony all around my home. I really like the scented beeswax candles, and could almost swear they are helping to clear my sinuses. I am a retired auto technician and can really appreciate the engineering and quality that went into this machine. BRAVO!!! WELL DONE. And it came in 3 days! Mesmerizing to watch also. THANK-YOU SOOOO MUCH. – Paul USA
Congratulations on a beautiful little machine
As the twinspeed fan was to be a Christmas present (for myself) and I had no idea of delivery time, it was ordered in plenty of time. It was delivered very promptly, so had to be kept under wraps for the best part of the month. It is beautifully crafted. I note that the fan is direct drive with a bigger fan rather than a geared-up belt drive as illustrated. I think this is more elegant and avoids the procurement of replacement drive belts. We have used a thermo-electric fan for some years. That is rather smaller and operates at lower temperatures, but is nothing like as interesting in operation. Placement of the Twinspeed is more critical because of its relative size but can be accommodated within the footprint of the stove top, fortunately there is no flue to beware of. I have yet to work out how to realistically compare the performance of the two fans, but the real beauties of the Twinspeed is its aesthetic appeal and as a demonstrator of the principle of the stirling cycle and, hopefully, a teaching aid for some of the laws of thermodynamics, I look forward to the grandchildren being old enough! Congratulations on a beautiful little machine. I look forward to many years of service. – Bob United Kingdom
Performance exceeds our expectations
We received our fan very punctually and were delighted with the quality and workmanship. We have already tried it out, the performance exceeds our expectations and our visitors are fascinated with the mechanism! The service is exemplary and we would not hesitate to recommend both the product and the company. – Andrew United Kingdom
The level of workmanship is superb
Just received my steelhead fan and I’m absolutely wrapped. It arrived in Australia two weeks after ordering and is more beautiful than it looked in the photos. The level of workmanship is superb and most importantly works as described. Mesmerising to watch; a welcome addition to our home. – Jim Australia
You made me very happy
You made me very happy with your really nice engine!!! And I was surprised when the postman came with your (very professional) packed engine already three day’s after my order- from the UK to me to Germany!!! The function is as perfect as the engine looks like. I also like to let it run if I don’t need to distribute the heat in my living room. I enjoy this engine every day if I enter my living room!!! Thank you very much indeed!!! – Gerhard Germany
Great present for the man who has everything
Thank You – Husband told me ages ago he wanted a stove top thermometer from yourselves so I remembered the name. Needless to say he was very happy. He said he loved the engineered piece of equipment! He is very pleased and it does look great. Arrived really quick as well. Great present for the man who has everything. – Carrie UK
Very pleased to add this engine to my collection
I have had my Windjammer for about three weeks now and it easily has over ten hours operating time. The build quality and materials used are A1! I have set my wick flush with the top of the burner neck and with this small flame the engine can be started within a minute. Once warmed up, the engine has a good speed with this small flame and no noise or vibration! Very pleased to add this engine to my collection! – Chris Canada
5 Star Fan
I just want you all to know that I’m extremely pleased with your product!!! Shipping to the USA was super quick-(4 days) with a tracking number so I knew when it would arrive. The quality and craftsmanship is more than I expected. This fan will pay for itself in about 2 years and will last for many years, probably generations. A YouTube channel called Wranglerstar showed, in detail this very same fan that he had in his shop, I was instantly interested and determined to get one. Thanks Again, from across the pond. – David USA
Impressive, precise and beautiful piece of engineering
Thank you for my Glasshopper Stove Fan. The product came very well packaged and no damage was incurred during transport. I appreciated getting updates on tracking progress. The fan is certainly a very impressive, precise and beautiful piece of engineering. I enjoy explaining to people how it works. Warpfive was very helpful in answering my queries. – Andrij Australia
Efficiently and gently wafts warm air
Our fan sits on top of the wood-burning stove in our lounge. It is very satisfactory: it is appealing to look at and it efficiently, and gently, wafts warm air across the room when the stove is in use. Keith UK
I'm delighted
I bought the Glasshopper fan recently (as a birthday present to myself; always safer to buy one’s own) and I’m delighted. It is a lovely piece of engineering, and beautiful piece of kinetic sculpture. Both my father (84) and daughter (10) are entranced by it. The fact that it works at lower temperatures is ideal for our stove which has a cooking section meaning it’s top does not get so hot. Well done Warpfive and well done Rev. Dr Stirling! – Antonio UK
I absolutely love it
Got the Windjammer 2 today. I absolutely love it. Thank you – good job! I have a fairly large collection of Stirling engines but no fan – until now. It’s a wonderful and much appreciated addition. I’ve been running it for the last half hour – it’s perfect. The workmanship is gorgeous. It will be frequently enjoyed for a very long time – Mark USA
Exceeded all expectations
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. – Simon United Kingdom
Couldn't be better
We are delighted with the red Steelhead engine we bought. It’s quiet with just a faint reassuring mechanical noise when going at full chat which adds to it’s charm. It is also noticeably effective in transferring heat more evenly around the house. Couldn’t be better! Thanks – Pat United Kingdom
Customer service is second to none
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!! – Adam United Kingdom
Technological art
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.’ – Dave UK
Fan is very quiet
I have been using a Warpfive Steelhead fan for two weeks, the build quality and design is superb, the detail engineering is so impressive. The fan starts quickly and creates a ’soft’ air flow without being intrusive, and really helps to create a uniform temperature throughout our large room (about 25 Sqm), it’s also an immediate talking point with guests. Is it noisy? our fire makes more noise than the fan and it’s quiet, the Warpfive fan is very quiet, down to precision of the engineering. Thrilled with the purchase highly recommend it to anyone. – Chris UK
We don't know which is the best feature
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.’ – Adrian & Denise United Kingdom
Great piece of industrial design
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 – Mike United Kingdom
Modern, stylish & effective
It is a beautifully made fan and its appearance is modern, stylish and effective. – Paul UK
A truly excellent experience in dealing with you
THANKYOU. Fast, accurate and a truly excellent experience in dealing with you from the first phone call to the delivery. The Twinspeed is everything your website and YouTube hinted at. A great addition to heating our house and it’s also good enough simply to stare at!! – Bill UK
