Beat the cold spots with the best wood stove fan!

Best Wood Stove Fan Guide

Isn’t it annoying to shift from that comfortable position because sitting next to the stove is too hot and you have to move back closer to the stove because sitting far is cold?

Well, after weeks of searching, you’ve bought what should be the best wood stove or pellet stove on the market, and you have paid good money for it. But, did you buy a wood stove fan alongside the stove?

If you don’t get the fan you will end up paying more for the wood fuel. As painful as it sounds, the stove leaves cold spots in the house because it will only heat up the surrounding air meaning you only feel the warmth sitting close to the stove and the furthest side of the room will feel colder than the rest of the room.

What does a wood stove fan do?

How Wood Stove Fan Works
Illustration: dhgate.com

As implied above, a stove fan which modulates hot air circulation in your living space, will increase the efficiency of the stove and heat up the whole house effortlessly.

There are different types of fans with, but they all result in warmer spaces. The best bit is that the right fan is easy to use, appealing, and easy to maintain.

But, warming your home is not all you can expect from the fan: a great fan enhances air circulation, its cost saving, and it boosts air flow, and enhances comfort.

How it works?

The fans are heat activated. What this means is that heat drives the fan. After you ignite the wood, the base of the fan must reach a specific temperature (varies with the kind of fan in use) for the conversion of thermal energy into electric energy using a thermoelectric motor that spins the blades.

The spinning of the blades results in the rotation of the fans which pull air in the process. As the blades spin, the heat radiates throughout the room, and it doesn’t just rise vertically or heat up the ceiling.

The best bit is that the fan will work automatically. Thanks to the fan, your stove’s output increases and you just might end up using less fuel because the whole room is warm enough.

Note that the temperature difference in a room easily forces more heat production and even with a thermostat, reaching the optimum temperature is harder when you have hotspots and cold spots.

No Electricity Needed – Yes, You Heard It Right

Best Electricity-Free Wood Stove Fan

Wondering if the fans are as effective as we are made to believe? Yes, they are.  Despite the small size of the fan, it’s powerful enough to move a substantial amount of air (cubic feet per minute) in CFM. The best bit is that the fans do not require any power source – no cables and no batteries.

How then do they work without a power source? The fans are powered differently using either TEG (Thermoelectric Generator) where the fans rotate from the power of the TEG module temperature differential or Stirling engines, the external combustion engines which are fuel by the heat from the stove.

So, all you need is burning wood to balance the temperature difference between the hot spots and the cold spots.

Below is a demo video how the stove fan is activated with heat.

Efficient in Room Heating

The efficiency of the fan will depend on the space available above the stove and the size of the room you intend to heat up. For bigger rooms, you need a higher air-moving capacity.

To boost the efficiency of the stove and for safety reasons, we recommend getting a stove top thermometer for optimal function. Note that the stoves operate well at a range of 150 °F or 65 °C and 650 °F or 345 °C.

At low temperatures or when there is little wood burning, the fan will slow down and eventually stop spinning if you don’t add more wood.

Characteristics of the Fans for Wood Stoves

  • CFM rate: This refers to the number of cubic feet of warm air circulated by the fan. If there is a big difference in the amount of air circulated by the fan, then the fan will warm a bigger part of the house.
  • Start-up temperature: What is the minimum temperature needed for the fan blades to move on their own? Do you run your stove at a lower temperature? If you do, you might have to get a fan with a low starting temperature, and if that is not the case, you might have to start the fan manually by spinning the blades.
  • Design: The design of the fan determines whether your stove looks great or terrible
  • Sensitivity: The fans will only work on stoves that can reach a specific minimum temperature because the fan must reach a certain temperature before the differential temperature at the bottom of the stove and the top is high enough for the blades to rise. While some stoves require low-temperature fans, others require very high temperatures.
  • Fanning ability: The fan only works best if there is enough space at the back because it will draw in cool air from behind for power. You need at least 15cm space behind the stove.
  • Quietness: The fans are fairly quiet even for the inexpensive and low-end models.
  • Automatic controls: The best fan for your stove comes with automatic controls, and you don’t have to manually switch it on and off when the desired temperature is reached. The controls also enhance energy efficiency.

Note that it doesn’t matter whether you are using a pellet or a wood burning stove, or if the stove is catalytic or non-catalytic.

Fan Safety

The fan has an inbuilt safety system which protects the motor from damage. When the surface temperature is above 250 degrees Celsius, the safety strip located at the base of the fan will slowly lift the fan away from the heat source. The strip also prevents overheating.  Once the maximum temperature of the fan is reached, the safety strip will lower the fan back down and closer to the heat source.

Safety Precautions Around the Fan

  • If you have young kids, keep them away from the fan because of the open blades and watch them closely especially when the fan is running.
  • Use a high-quality stove thermometer for your safety
  • Don’t touch the fan while it’s on use
  • Don’t set the fan on an unprotected surface when it is not and if you have to carry it, use its extendable handle wearing gloves.
