Guide: Questions you should ask yourself before buying a stove fan
What is a stove fan?
Maybe you've had the idea of putting a normal fan on the stove. The principle is already good, but it is certainly not optimal. After all, the fan makes a certain amount of noise and the heat is not the best for the cold air fan either.
If you are wondering how to solve this problem, you should consider buying a stove fan.
Such a stove fan is placed on the chimney and as soon as the stove is lit, it does its work all by itself. It distributes the warm rising air from the stove throughout the room through the individual blades.
How does a stove fan work?
The way a stove fan works is quite simple. It is based on the principle of thermoelectricity, which means that you do not need electricity or a battery. A thermocouple is built into the bottom of the stove fan. As soon as the stove burns and thus generates heat, this thermocouple heats up.
The result is that the lower part of the fan is much hotter than the upper part. In addition, both areas are equipped with a different material so that a temperature difference can be created.
This temperature difference is used to create heat conduction through electrons. This means that there are many electrons with high energy at the bottom of the fan. At the top end, it is logically the other way round. The electrons with a lot of energy want to go up and the electrons with little energy want to go down. This interaction creates a voltage inside.
This tension is now responsible for the wings moving. These wings, on the other hand, ensure that the rising heat from the stove is distributed in your living room. The more hot air there is, the faster the blades turn and the better the heat is distributed throughout the room.

Which stoves can I use a stove fan with?
The other requirement is that the stove fan must be able to stand freely in the room. After all, it must be possible for you to place the fan on top of the stove so that it can distribute the heat in the room. The stove fan is therefore not suitable for permanently installed stoves without such a support surface.
In the following, we have compiled a table that shows you which stoves you can use a fan for.
|Fireplace stove||Yes||Up to 300°C is reached at the stove pipe|
|Tiled stove||No||Only 50°C - 90°C is reached|
|Open fireplace||No||Most of the heat is given into the room|
|Pellet stove||Yes||Up to 300°C is reached at the stove pipe|
|Storage stove||No||Only 50°C - 90°C is reached|
|Radiator||No||Max. 35°C is reached|

Decision: What types of stove fans are there and which is the right one for you?
What distinguishes a Seebeck effect stove fan and what are the advantages and disadvantages?
The Seebeck effect is the most popular way of operating a stove fan. The thermocouple built into the base of the fan is heated by the correct location, which is on the stove, and so the electrons at the base of the stove fan have a very high energy.
The electrons in the top of the fan, which must be made of a different material or the heat will be conducted, have a low energy. The electrons from above want to penetrate downwards and the electrons from below want to penetrate upwards. The interaction generated in this way creates a voltage inside the fan that causes the rotor blades to start moving.
However, for all this to happen, a certain minimum temperature is required, which can vary from model to model.
What are the characteristics of a Stirling engine driven stove fan and what are the advantages and disadvantages?
A Stirling fan is a hot-air fan that generates mechanical energy through thermal expansion of the air. In terms of general construction, Seebeck and Stirling engine devices are very similar.
The only difference is that the Stirling engine modifies the Seebeck effect a little. The fan now converts the heat into mechanical energy with the help of a working gas. This gas, which is enclosed in the fan, is heated and fed into the engine and then the energy is transferred to a flywheel, which serves to operate the propeller.
Due to the design with several small parts on the fan, it is more sensitive to dust and may not be able to start by itself when the minimum temperature is reached.
Buying criteria: Use these factors to compare and evaluate stove fans
In the following, we would like to show you which factors you can use to compare and evaluate stove fans. This will make it easier for you to decide whether a particular stove fan is suitable for you or not.
We have tested the following criteria for you:
- Operating temperature
- Number and diameter of rotor blades
- Material and weight
The operating temperature is one of the most important features when buying a stove fan. It indicates the temperature at which the fan starts working.
When the oven is first heated, the temperature is still low and the fan turns very slowly. In addition to the initial temperature, the manufacturers usually also specify the optimum operating temperature at which the fan will rotate at its full capacity. This is usually between 100 and 120 degrees.
In the following, we have compiled a small table that shows the temperatures at which most oven fans perform their work.
|Temperature||What does the oven fan do?|
|Below 65°C||It's too cool for most, they don't spin|
|Between 65°C - 150°C||It's hot enough for some fans, the blades spin|
|Between 150°C - 345°C||Hot enough for all fans, the blades spin|
|Above 345°C||Too hot for all oven fans, there is a risk of damage unless the model has overheating protection|
Number and diameter of rotor blades
At first glance, you would probably think that the more rotor blades the better the fan. But this is only partly true. The more blades a stove fan has, the more air it can move at a low speed, but this also requires more energy.
So it depends a lot on your stove. If the temperature on the stove is already very hot, you can go for a fan with 6 blades. But if your stove only just reaches operating temperature, then you should buy a stove fan with only 2 blades.
The length of the blades also plays an important role. It is said that the length of the blades in centimetres corresponds to the maximum square metre size of the room.
Material and weight
In most cases, the casing of a fireplace is very hot. Therefore, the stove fan must also be heat-resistant accordingly.
Most stove fans are made of steel or aluminium. These materials have a very high melting point and are therefore ideally suited for the fireplace. Despite this fact, many operating instructions state that you can use a stove fan up to a maximum temperature of 350 to 450 degrees. So if your fireplace surface gets very hot, you should pay attention to these maximum temperatures when buying.
The weight is usually between 0.5 kg and 1 kg.
Another important criterion is the noise level of the fan. Most stove fans are almost silent.
The basic rule is that the more blades there are, the quieter the fan. Most of the time, the noise level is indicated and for most of them it is 25 dB or less. The noise is so minimal that you almost don't notice it.
Facts worth knowing about the topic of stove fans
How do I place my stove fan correctly?
First of all, make sure you have a surface directly above the stove. Then you should wipe this surface clean with a damp cloth. When placing the fan, it is important that the bottom of the fan is directly above the heat source.
If you place the fan on the back corner of the fireplace for aesthetic reasons, this has several disadvantages and is useless.
Make sure that you place the stove fan on the front edge in the middle of the stove without it falling over. The propeller head should point to the centre of the room.
There are also models that you don't have to set up, but attach to the stove pipe. But don't get the nonsensical idea of drilling a hole in the pipe. Depending on the manufacturer, there may be heat-resistant adhesive tape or a strap included in the delivery, with which you can easily attach the stove fan to the stove pipe.
How do I care for my stove fan properly?
It is recommended that you clean your stove fan regularly. This is because although most smoke and soot are carried through the stove pipe, small amounts also pass through the door to the outside and thus onto the blades of the stove fan. This makes them heavier, which in turn leads to increased energy consumption.
Cleaning every 3 to 6 months is recommended.
You don't have to pay much attention to the cleaning itself. You can remove the fan and clean it in the sink under running water with washing-up liquid. Just make sure that you do not use any aggressive detergents or steel wool, as these can damage the material.
If dirt has accumulated on the turning screw, you can clean it with a toothpick or cotton swab.
During the summer months, you will not need the fan, so it is advisable to store it in a box and protect it from moisture.
How can I build a stove fan myself?
A stove fan can also be built yourself with a certain amount of craftsmanship. Due to the generally low price of these fans, we advise you not to do so.
However, if you really want to build a fan yourself, we have selected a video that shows you the necessary steps to build your own stove fan.
