  • Fan heaters suck in cold air and blow it out hot again. So they can warm up a small area in no time.
  • Fan heaters are particularly useful in rooms with humid air: such as the bathroom.
  • The small fan heaters use a lot of electricity and are not suitable for continuous heating.

1. All hot air: when a fan heater makes sense.

To clear up with a misunderstanding in advance: fan heaters are not suitable for permanent heating. The fan heaters are perfect when a small area needs to be very warm for a short time, This can be for example a children's room in the apartment or a bathroom.

The small electric stoves blow warm air into the room.

Like a fan, they suck in the air and blow them in one direction - with the difference that they heat the air. Heating the air makes it very dry, In damp rooms, such as a bathroom, this is an advantage. In normally dry rooms, however, the mucous membranes of the eyes and nose can dry out uncomfortably.

In cold seasons, however, mold settles particularly fast in bedrooms and bathrooms. In 2013 Stiftung Warentest surveyed more than 4,000 people about mold in their homes. Many confirmed that bathing and sleeping rooms are vulnerable. In these cases, even a mini fan heater can achieve improvements.

Fan heaters can also be referred to as fan heaters, but should not be confused with a hot air blower. Hot air blowers are tools that heat workpieces at points and look very similar to hairdryers.

2. Ventilated secrets: buying advice for fan heaters

2.1. application

When buying a heater fan, pay attention to the IP protection standard: The second digit stands for the degree of protection against liquids: the higher the better.

The location is crucial when choosing a fan heater. If you want to use the outdoor fan heater on the terrace or in the bathroom, many devices will fall out. Not every fan heater is splash-proof, With at least one IPx2 certification, the manufacturer promises that splashes of water or water vapor will not cause a short circuit in the device.


There are also car-heater with 12 volts, which can be operated by cigarette lighter. However, they are only suitable for minimal premises such as the cab of a car. Battery powered models fall here, however, more in the field of curiosities.

On construction sites occasionally gas fan heaters are operated, which are optimally protected against rain and are thus also suitable for use in the garden. However, you always have to have a gas bottle at hand here.

Here is a brief overview of the most important types of IP protection for water:

IP digitmeaning
IP X0No protection against liquids.
IP X1Protected against vertically falling drops.
IP X2Protected against water spray that can run off.
IP X4All around protected against splash water.
IP X6Also withstands heavy rainstorms.

2.2. Performance vs. performance efficiency

Especially in the vicinity of shower or sink is worth a protected against splashing heater.

High wattages are not a guarantee for a powerful fan heater. The wattage is just an indication that the device can get very hot. High heating efficiency is more important than high wattagebecause if the heater fan is well designed, it can already give off a lot of heat with little power.

Although heating efficiency is the most exciting value for a fan heater, it is not indicated by all manufacturers. In this case, you have to be geared to the wattage.

Another indication of the heating capacity is the maximum room size: Unless you install the radiator in an old apartment, given room sizes provide a good decision-making aid. In old apartments with high ceilings, the heating output may be halved.

2.3. Filtered luck

Fan heater comparison 2018: heater

Replaceable filters improve the breathing air in the room.

What distinguishes a fan heater test winner from average fan heaters are built-in filters. Fan heaters also collect dust and grime with the air, which they heat up and blow into the room. A filter captures contaminants before we breathe them, Especially for allergy sufferers and children, the filter is important.

If such a filter is present, it should be removable. On some models, the filter can be washed in the washing machine or be replaced by new filters. Especially with cheap fan heaters, this useful feature is often missing.

2.4. From frost to overheating protection

Electric heaters or fan heaters with a so-called "frost protection" start independently with the heating. This is triggered by different events because Frost protection is not the same in all fan heaters: Either has the small "frost guard" in the garage a built-in thermostat, which turns on the heater above a certain temperature or in the electric fan heater is a timer installed.

The timer is a timer that turns on the electric heater at a pre-defined time. Usually this time is at night when temperatures drop.

Too much hot air

Even electric heaters can overheat. So if you plan to run the fan heater for a long time, the unit should have overheating protection. This circuit disables the device before it burns out.

Little guard: With electric heaters that get too hot, the built-in electronics may melt and cause a short circuit. Kurschlüsse lead quickly to fires. Overheating protection prevents this.

2.5. Cold Stage, Oscillation & Remote Control: A matter of comfort

Fan heater comparison 2018: 2018

A self-rotating fan heater distributes warm air optimally.

When a fan heater has a so-called "cold stage", it blows the air into the room without heating it. In that sense, it works like a fan.

If there is also "oscillation" on the packaging, the fan will swing back and forth independently. With this function, the air, whether cold or warm, is better distributed in the room.

Fan heaters with remote control can be operated comfortably from the sofa. Just when the heater is hanging above a wall-mounted fan or in the back of the room, you will enjoy the benefits of a remote control.

Since fan heaters are rarely quiet, the idea quickly comes up not want to sit next to the device. So you prefer the heat levels from afar.

3. What should be considered when heating ventilation:

Fan heater comparison 2018: heaters

The freer a fan heater is, the more efficiently it heats the air.
  • site
  • electricity costs
  • dry air vs. allergy

3.1 Site & Costs

If an electric fan heater is placed correctly, you will receive two advantages at once: better heat output and higher safety.

power consumption

The fan should be free on all sides. On the one hand, so that he can suck in air easily and on the other, so that he can blow it out just as easily. The more free air circulates through the device, the less effort it has and the fan heater remains moderate in power consumption. However, heating fans are not energy efficient compared to permanently installed radiators.

The principle of the fan heater relies more on quick heaters: They heat up a small area quickly and cost-intensive, If you want to save energy over a long period of energy, you should look for large radiators such as heating convectors. Water-carrying heating systems also help to distribute the heat in the house.

Textiles should not come too close to the fan as they may catch fire.

Whether Drahtheizwendel- or ceramic fan heater, in both everything is heated, which comes to the glow rods. Therefore lint burn there like crumbs in a toaster. If a curtain is too close to the fan heater, it can catch fire.

3.2. Dry air

In a damp bathroom, it may be very handy if a ceramic heater sucks in the moist air and dries. But in a baby room, this can be harmful to the child.

Similarly, house dust allergy sufferers will have little enjoyment of too dry air, because their nasal mucous membranes are often attacked and the blower sends even more dust than usual in the air. If you want to avoid dry air and too much dust, you should only use a fan heater to a limited extent and pay attention to washable filters.

3.3. More air

Even if a fan heater does a good job of fighting mildew in damp rooms, that's not all: Regular airing helps to improve indoor air quality, This is useful for both humid and dry air.

4. Frequently asked questions about fan heaters

Fan heater vs. radiators

Radiators emit heat as infrared radiation. Infrared radiation only heats objects that can reflect light. This means, Radiators heat up practically everything except the air.

Whether electric, gas or oil radiator: they emit all infrared radiation and are, so to speak, "heat wave heaters". Fan heaters, on the other hand, only heat the air.

4.1. What is a fan heater?

Fan heaters are like fans with integrated heating. So they heat the air similar to a hair dryer and are roughly categorized among the convector heater types.

"Convection" here means nothing else than that heat is transported through a medium. This "means of transport" can be air, water or oil.

A "convector radiator" (also convector heater) differs from an infrared radiator in that it does not radiate heat directly, but instead needs its "means of transport".

So oil, water or air is heated centrally in furnaces and directed to the individual convector heaters. These then heat the ambient air in the rooms.

Air as a heat supplierIn a vacuum, for example, a convector heater would not heat anything, as the means of transport "air" would be missing. However, an infrared heater would easily heat up objects in a vacuum because it heats with radiation - like the sun.

4.2. Why are fan heaters stinking?

Fan heater comparison 2018: heaters

If fan heaters smell strange, they are not necessarily broken: the smell vanishes. For older models, cleaning may be sufficient.

Since the fan heaters suck not only air, but also dust, lint and other dirt in their radiator, these small particles burn there and occasionally spread an unpleasant odor.

In addition, new heaters at the beginning almost always have a natural odorthat literally vanishes over time. This problem is independent of the quality of the product and can be found in many fan heaters tests again.

So do not be surprised if your new Ceramic Fan Heater smells a bit after buying.

4.3. How long can you run a fan heater?

A fan heater should only be operated under supervision, as there is always the risk that a piece of paper or fabric will catch in the fan and catch fire.

Apart from that, the mini fan heaters (and even larger models) can run for several hours. Here, however, the high power consumption should be considered. Potentially runs a heater without problems for several hours at a time, The best fan heaters have a built-in overheating protection, so that the electrical system does not get a short circuit.

4.4. How do I clean a fan heater?

When the small electric heater with blower begins to spread an unpleasant odor, it is time for a cleaning. Many models have a built-in filterwhich is easy to remove.

These filters can either be completely replaced or washed. If your model does not offer any of these options, you can also aspirate the device.
