Wood stoves have been around forever – almost literally, and the very first wood-fired stove in basically the form we know today was patented in Germany more than four and a half centuries ago. In recent times the humble wood stove has rapidly regained popularity, and today they are really all the rage.

This is easy to understand, with high fuel prices and utility bills, concern about the economy and a general trend towards a more simple and basic life and lifestyle.

Why do I Need a Heat-Powered Wood Stove Fan?

But while wood stoves have many advantages, they have always had one problem – circulation. They take a long time to heat up a room and don’t always keep the air warm all throughout the space.

But this is where a heat-powered wood stove fan can help. 

An amazingly simple idea, the heat-powered wood stove fan sits on top of your wood stove and blows the hot air throughout the room, heating the area more quickly, making sure much more of the space is warmed and decreasing wood consumption – a lot!

How does a  Heat-Powered Wood Stove Fan work?

All heat-powered wood stove fans work by using heat from the stove to turn a high-efficiency fan, which moves the hot air from around the stove throughout the room. They don’t require batteries or any other power supply – just the heat from your stove.

There are two basic types of heat-powered wood stove fans:

  • Thermoelectric Generator: This uses the difference between the stove’s heat and the fan’s cooler temperatures to create a tiny amount of electrical current, which drives the fan.
  • Stirling Engine: This type of engine creates no electricity at all, but simply uses the movement of heated air from a small, compressed space into a larger space in order to move the mechanism which turns the fan.

Both methods are ingenious and quite effective, but the Stirling engine is more expensive, and thermoelectric generators are much more common.

What are the Advantages of a Heat-Powered Wood Stove Fan?

Heat-powered fans are becoming incredibly popular, and if you have ever felt their effects you can understand why. For all of their simplicity, they offer numerous advantages, including:

  • Heat powered stove fans are quite inexpensive
  • They have absolutely no running costs
  • They help your stove heat a room faster
  • They distribute heat all throughout the room
  • Heat powered wood stove fans will dramatically reduce your wood consumption (20 Percent or more!)
  • They are whisper quiet, or even silent
  • They are a great conversation piece

Are there any Downsides to Heat-Powered Wood Stove Fans?

Not really, although you do have to be careful with your fingers (they are open fans), and they will get very hot, as they sit on top of the woodstove. As such, you have to exercise caution with children – although it has to be said that if your kids are that close to the wood stove you have bigger problems than a little fan.

How do I Choose the Best Heat-Powered Wood Stove Fan?

Don’t worry, we’ve taken care of it for you.

Heat-powered fans are incredibly popular, and as a result, there are hundreds of different models on the market, many quite good and some pretty poor.

What is the Best Stirling Engine Heat-Powered Wood Stove Fan in 2021?

Warpfive Steelhead Heat Powered Stirling Engine Stove Top Fan

The Warpfive Steelhead is an expensive fan, and the question inevitably arises: is it really worth the money?

We would have to say yes, without a doubt!

For one thing, it is easily the most beautiful wood stove fan we’ve ever seen, with a level of fit and finish even Ecofan can’t quite match – hand made in the UK of aluminium, brass and stainless steel, and with a prideful individual serial number laser etched onto each fan’s base.

More importantly, it is the best-performing heat powered wood stove fan we’ve found and works better than any other on our list.

The Warpfive Steelhead will operate safely up to an extreme top temperature of 842 degrees Fahrenheit, and puts out over 320 cubic feet of hot air per minute – more than most politicians!

But, in the final analysis, we may just love the Steelhead because of the remarkable technology involved.

Indeed, the Stirling engine is so amazing, so efficient and innovative, that today scientists and engineers in many different areas are using Stirling engines in their most advanced applications – a full 200 years after Robert Stirling first came up with the idea.

And the simple heat transfer process – unlike the thermoelectric generators used in other heat-powered wood-fired stove fans – makes or creates no electricity, using only the movement of air to spin the fan.

Yet we really aren’t ones to praise or recommend tech just for tech’s sake and should mention that the amazing Stirling engine isn’t just exceedingly cool – it is also responsible for the Warpfive’s best-ever performance and extreme reliability.

And that is what our 2021 buyer’s guide and review of best wood stove fans are all about – finding the heat-powered fan that works the best, will save the most money and will keep you warmest. And, in ever count, the answer is Warpfive!

So, the Warpfive Steelhead Heat Powered Stirling Engine Stove Top Fan is a beautiful fan, a teaching piece, conversation starter and wonderful curiosity, is extraordinarily well made, and is the most effective wood stove fan we’ve ever found – our choice Best Stirling Engine Heat-Powered Wood Stove Fan in 2021, and recommended without reservation!

Do Heat-Powered Wood Stove Fans Really Work?

It is easy enough to explain the technology behind a heat-powered fan, and even easier to spout off specifications and manufacturers’ claims, but perhaps a bit harder to really relate just how much of a difference one can make.

You see, it’s not just in how much air it moves, how silent it runs, how much it may increase the temperature or how big of a room it works in.

It is about how you will feel in that room. You will be amazed at how much more quickly the air is warmed and comfortable, and you will move around without that familiar chill that comes from moving out of the stove’s effective zone – suddenly the whole room is the effective zone!

Getting warm faster and being able to move around without losing that warmth, and knowing that everybody in the room can feel the warmth, these are great feelings. But let’s not forget the other warm feelings – saving money, and not having to go outside as often to chop wood!

We hope you’ve enjoyed our detailed report – Best Heat-Powered Wood Stove Fans: 2021 Guide – and we hope that you love your new fan as much as everybody here loves ours!
