Fan heater purchasing guide


Choosing the right fan heater for your particular needs is challenging and requires some prior knowledge. Below you will find some tips as well as a list of facts to help you with the purchase of the ideal heater.

Room size

Not all fan heaters are appropriate for all room sizes. Find out prior to purchasing which heater is appropriate in your case. Generally speaking, manufacturers work on the basis of a 2.5 m room size.

Intended use

A heater is suitable for many areas. For example, in your living room, children's room, kitchen, bathroom, study, garage, hobby room, recreational vehicle, gazebo or in the event of a failure of your central heating system. Please note that IP21 protection is imperative when using a heater in the bathroom.


There are different types of fan heater technology: PTC ceramic heaters, fan heaters, quartz heaters, oil-filled radiators or infrared heaters. The respective technology is chosen according to individual well-being. That is why testing the different technology types at an approved retailer is recommended.

Power consumption

Power consumption is only very high if attention is not paid to the time and the level at which the fan heater is running. Exactly as much power is consumed as is stated for the performance (power in Watts) of the fan heater. Consequently, heaters are by no means power guzzlers as they produce the same amount of energy as heat as they consume.


With fan heater, it is not only the decibel level that is to be observed as this involves a consolidation of different frequencies. A frequency can, therefore, be very disturbing even though the decibel level is within the tolerance range. It is therefore recommended that you hear what the fan heater sounds like in operation in a quiet environment in the shop prior to making the purchase.

Technical equipment

Nowadays, great importance is placed on technical equipment. With regard to fan heaters, this manifests itself in the number of heat levels, whether there is an integrated thermostat, or whether the fan heater even regulates the heat levels automatically, as is the case with Adaptive HeatTM in the fan heater Paul. There are even fan heaters that come with a remote control.

  1. Room size

    Room size is an important factor as not all heaters are suitable for large rooms, or it can take too long to heat a room. For this reason, we recommend measuring the room size first of all and then selecting the right heater.

  2. Overheat protection

    Make sure that your heater has overheat protection so that you can leave the room without having to worry.

  3. Tip-over protection

    Thanks to tip-over protection, the fan heater stops heating automatically as soon as the appliance tips over. This protection is especially important if children knock the fan heater over.

  4. Noise level

    Find out about the noise level prior to making the purchase. Decibel levels alone are not sufficient. It can also be the case that noises occur at a low decibel level which can be subjectively perceived as disturbing. It is best if you listen to an appliance at an approved retailer.

  5. Performance per Watt

    Note the performance of the fan heater. Some are very powerful (approx. 2'000 W) while others are rather weak (approx. 500 W). The more heat energy required, the more powerful (higher Wattage level) the heater should be.

  6. Power consumption

    Power consumption is an important topic when it comes to fan heaters. The fan heater consumes exactly as much power as it ultimately reproduces in heat output. For example, a 500 W heater consumes precisely this amount in power (Watts). Consequently, heaters are by no means power guzzlers as they produce the same amount of energy as heat as they consume.

  7. Temperature control

    Ideally, you switch on your fan heater once and it will regulate itself independently from that point on. Ensure that your fan heater has temperature control (integrated thermostat). This means you won't spend much time constantly making manual adjustments to the temperature by turning the heater on and off.

  8. Heat levels

    Find out about the heat levels available prior to making the purchase. This will allow you to regulate your fan heater precisely as and when you need to.

  9. Transition period (spring / autumn)

    The transition to spring and autumn can be made more pleasant with a heater. The heater serves as a very good complement to your central heating system if this has not already been switched on or has already been switched off.

  10. Frost protection

    Ensure that your chosen heater has a frost-protection function, for example, in order to prevent frost formation in your holiday apartment or gazebo. Frost can be prevented if the heater sustains a uniform temperature over a longer period of time.
