The Twinspeed Stirling engine 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.
It’ll 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 Stirling engine 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. Find out morehere
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 am a fan (sorry about the pun) of Stirling engines. The Twinspeed is my third and the largest I have to date. I did not purchase the unit for air movement but more as an enhancement of our wood stove. The quality is excellent and it worked right out of the box. The other two Stirling engines required assembly and I was happy to simply unpack and use. The Twinspeed is so quiet and that is testimony to the quality.
Our wood stove is too big for the size of the house and we don't have to keep a hot fire going all the time. As a result the stove top regularly drops below the minimum for the Twinspeed to operate. The downside of Stirling engines is they don't self start. When I put wood in during the night I don't stay up long enough for the stove to heat up and I can start the engine so it is not running for a good part of the day. I expect the engine would run continuously on a smaller wood stove.
Stainless steel turns a bronze colour with heat. The base of the Twinspeed has taken on a wonderful bronze hue that adds to its beauty.

Very cool!
Received my fan right on time, and used it right away. It runs very smooth and quite. I use it along with a couple of electric fans which seems very loud, but I feel is necessary to move the wood stove heat to where it’s needed. We recently had a power outage and only used the Warp5 fan, and it did a great job by itself!
It is a very high quality and everyone who sees it is always drawn to it!

Precision engineering
Received my Warpfive Twinspeed fan a week ago but couldn't try it out as was wanting to give the wood burner a clean and reseal around the flue connection. Got that completed today and tried out the fan, really impressed with how smooth it is. I would recommend this fan to anyone, precision engineered and worth every penny.

Quality built Stirling fan
Received the Twinspeed today. When I was unboxing it, I could immediately feel the quality craftsmanship. I was hoping to receive it before it started to get cold. Shipping was very fast! Received the tracking number, and received it in 4 days (US).
Haven’t tried it yet, but when I do, I feel it will circulate the warm air in my living room.
If I may make a suggestion for the dust cover. Maybe make a cover out of high-temp pyrex, or plastic that could withstand a hotter temperature. I think I have enough space on top of my wood-burning stove to position it so the temperature won’t affect the cover.
I will update my review after it has run a few night.

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.

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.
