4 Blade Cocoon Fan


Too cold on the couch? Too toasty by the stove? Well, you can fix that problem of uneven heat across the room by placing the Cocoon Fan on your stove, so the heat from and around your stove is pushed outwards around the room.  

4 Blade Cocoon Fan

Since hot air rises, most of the heat from your stove simply escapes directly above and gets lost. That means you aren’t feeling the full benefit of your stove. 

The Cocoon Fan operates at a low starting temperature (140°F), which means your living space will be toasty in no time. Soon, every part of the room will feel comfortably warm, not just around the fire. 

Using the Cocoon Fan is the most economical way to effectively circulate warm air. It uses no batteries so it can be used where there is no electricity. The heat of the stove is conducted through the base of the fan and converted into ‘free’ electricity which powers the fan motor. 

While standing at just 8 inches tall, the Cocoon Fan moves up to 210 cubic feet of warm air per minute thanks to its innovative blade design. 

Moreover, it lowers fuel consumption by increasing the efficiency of your stove. Some stoves save up to 10% of fuel. 

With its effective, cost-saving design, the Cocoon Fan will blow your cold spots away.

✔️ Self-powered by the heat of the stove itself

✔️ Cost-effective: Save up to 10% fuel

‘How does this work?‘

Physics! This fan uses an innovative thermoelectric device to generate electricity directly from the heat of the stove to run the fan. The electrical energy is generated from the thermal energy flowing through the device from the bottom (hot) portion of the fan stand to the top (fan-cooled) portion of the stand. But most of all—regardless of how it works—it is effective! 

‘I don’t have a wood stove. Will this work with my pellet, coal, barrel, propane, etc., stove?‘

Yes, it can! The fan works on any surface that gets hot enough to cause it to generate enough energy to power the fan motor. The base of the fan just needs to get to around 60°C to start spinning, though the hotter it gets, the more powerful the fan will be. If you have a grate, insulation, multiple layers on the top surface, it is less likely to be a good option, but you could measure surface temp (e.g., drip a drop of water on it at full temperature to see if it boils would be one easy way) to see if it’s a good solution.

 ‘How many fans should I get?‘

If you have a large space requiring more circulation power (more than 6m by 6m), you might consider getting two fans—though, it is not necessary. About 20% of our customers get 2 fans or more to spread the hot air best.

‘Where is the best place to get the highest performance from my Heatspreader Fan?’

Place the Heatspreader Fan at least 100 mm away from the flue, so that it does not pick up the radiant heat from the flue. This will cause it to run faster, and for a longer time when the fire is low. If you wish to distribute the heat from the flue across the room, point the fan slightly towards the flue so that the moving air picks up the flue heat as well. In our experience, placing the stove fan towards the back of the woodstove, and pointing it into the room, works best.

‘Do I still need to dry my laundry right in front of the wood heater?’

Not anymore. You can air damp clothes much further away from the wood heater, and they will still dry quickly and evenly.
