Thermodynamic Fans = Simpler than they Sound

So, I’m not sure how many of you use a wood stove, but I’m going to post this anyway. We use a wood stove at my little homestead, so I generally spend a little time every now and then looking into wood stove-centered goods (pokers, fans, etc). During my searching, I’ve stumbled upon this cool little fan that answers a lot of my self-sufficiency problems with one fell swoop. Not only does it help me to circulated warm air from my wood stove around the room to help cut down on the wood that I burn, but it does it all with little to no input from me.

It’s called the EcoFan AirMax, and it packs a heck of a punch for a relatively small pricetag. Before I get into exactly HOW it works, let me tell you a bit about what you use it for.

See, when you use a wood stove, you need to go out of your way to get the heat around your home. After all, it’s really unsafe to try and add a bunch of pipes to your wood stove to take that heat to other rooms. Carbon monoxide and all that.

With this little fan, you can easily circulate that heat around your home. You don’t plug it into anything, and you just sort of let it do all the work for you without lifting a finger. Now that you know what it is, what it does, here’s how it works.

See, when you have a major heat differential in a room, it creates something called a thermal draft. When the differential is very great (say, between a cold room and a 400 degree wood stove), it creates enough of a draft to push the blades of a fan. As the blades move, it disperses the heat throughout the room, in a really nifty little experiment of thermodynamics.

As with any other cool eco-friendly addition to your home, it’s very easy to use and it doesn’t require much off a setup to get moving. If you’re looking for a way to make your wood stove more efficient, this is definitely the way to go.
